==Background==
===''Hobbyist's Guide''===
The development of the [[Guide: Defiant and Valiant|''Defiant'' and the ''Valiant'']] had created a significant pool of expertise and skill among the international construction teams. [[Earth]] still lacked the resources to mass-produce warp explorers, but the teams wished to push on with development of more practical warp drives and more useful exploration vessels. The national pride that had driven earlier space programs was
replaced by a combination of professional pride and competitive spirit, with the frighteningly advanced [[Vulcans]] as the opposing players.

In [[2052]], during the final stages of the econo-technological race against the [[ECON]], the [[United States|US government]] had begun to construct a large defensive space cruiser, tentatively christened the ''[[Guide:Seneca|Seneca]]'', for challenging ECON orbital supremacy in the 800-4000 km region. The vessel was in many ways just an enlarged copy of the ''[[Guide:Keldysh|Keldysh]]'' design, and something of a departure from the classic [[USAF]] spacecraft lineage. Indeed, the more traditional, less ambitious ''[[Guide:Guardian (USAF)|Guardian]]'' series of large manned combat spacecraft remained the budgetary favorite, and work on the ''Seneca'' was aborted before the outbreak of the war. In [[2064]], the ship was floating dead on a decaying orbit within the shrapnel cloud that had been [[Freedom Assembly Berth 02]] prior to the war. The warp development teams promptly attached a tug onto the hulk and towed it to the ''Valiant'' construction berth.

Within a year, the ship sported two 30,000 ton warp coil assemblies in hexagonal protective nacelles fashioned out of the lateral fuel tanks, and a three-chamber fusion powerplant with huge radiator surfaces bolted astern of the centerline tank. Her old national insignia were retained, but the registry and name were painted over to give room for the national symbols of the rest of the teams. Instead of the rather martial names chosen for the first warp explorers, the ship proudly carried the words “Bonaventure – the dream is alive” on her hull. Still, the ship was far from being a purely pacifist science project, as the financial backers of the project did not wish to see their interstellar envoy appear defenseless to the unknown dangers of space. Two laser emitters were installed on the arrowhead-shaped forward hull, and a full range of missile warning systems and glass bead emitters covered the propulsion modules and nacelle assemblies.

Since the ship was primarily intended to explore strange new planets, she required landing craft and remote mapping gear, neither of which was provided for in the original cruiser design. Two former USAF sentry platform maintenance shuttles were hauled from Earth and bolted onto the ventral surface of the fuel tank, and a selection of telescopes crowded the forward hull. A completely closed-circuit life support system was also installed for a maximum endurance of six years, representing a quantum leap over the primitive systems aboard the ''Valiant/Defiant'' ships.

The gigantic vessel fared better than the two initial survey cruisers: her second operational warp sortie under the command of Captain [[Hadrian Huckleby]] took her to [[Tau Ceti]] and, more significantly, back. Mankind’s first two-way interstellar journey had been completed in just eight years. During the following decade, the successful ''[[Guide:Columbus series|Columbus]]'' sublight explorers would also return to Earth, but too late to claim the honor. It mattered little that the ''Bonaventure'' went missing on her third mission, to [[Sirius]] – Earth had been firmly established as capable of interstellar exploration now, and would continue to expand its efforts in the upcoming years.

While the capability of Earth to construct something the size of the ''Bonaventure'' was severely limited in the postwar environment, scavenging of existing space structures would help Earth equip for its warp exploration spree. The basic structure demonstrated by the ''Defiant'', the ''Valiant'' and the ''Bonaventure'' would remain popular in early purpose-built warp vessels as well. A central fuel tank and reactor compartment flanked by two nacelles and mounting reaction engines and fusion powerplant aft, and an angular habitation compartment forward: all this would see service well into the mid-[[2100s]], although the amount of onboard fuel required would gradually decrease and thus free internal space for other applications.

[[Image:Bonaventure orbit.jpg|center|900px]]

The most direct successors of the ''Bonaventure'' would be the ''[[Guide: Messier|Messier]]'' class heavy cruisers, Earth’s first true interstellar warships that in the [[22nd century]] would be drafted to serve in the desperate struggle against the Romulans. However, the course of Earth warp technology was far from charted in [[2064]], and at least two major competing basic configurations would soon emerge. It is a matter of
some specieist pride to [[Human]]kind that the native ''Bonaventure'' configuration would persevere where the alien-influenced competitors would not.

===Delta Dynamics===
During the lead-up to the [[Third World War]] ([[2052]]-[[2053]]) on [[Earth]], the [[United States Air Force]] engaged in the development and construction of varying series of warcraft for the 800-4000 km orbital region. The vanguard of a large defensive space cruiser class was begun with the prototype ''Seneca'' at [[Space Station Freedom]]'s assembly berth 02. The ship was essentially an enlarged version of the Eurasian Confederation's ''[[Guide: Keldysh|Keldysh]]'' cruiser class. However, construction was halted late in the process in favor of the more traditional (and less ambitious) ''[[Guide:Guardian (USAF)|Guardian]]'' series of large manned combat spacecraft, due to budgetary constraints. By the post-First Contact period of [[2064]], the ''Seneca'' hull was in the dead-center of a shrapnel cloud in a decaying orbit. The international warp development teams tugged her into the now-vacant ''[[Guide: Valiant|Valiant]]'' construction berth, to become a more robust survey cruiser for the planet newly starstruck by a galactic manifest destiny.

The ''Seneca'''s lateral fuel tanks provided the protective structure for two 30,000-ton warp coil assemblies, with intra-system propulsion dependent upon the tried-and-true three-chamber fusion powerplant bolted to the stern of the centerline main fuel tank. Cooling was provided via the relatively large radiator surfaces of the main propulsion channel. The phrase "Bonaventure – the dream is alive" proudly broadcast the change in name and ''raison d'être''; the existing American pennant was joined by the pennants of the other partner nations. Despite the scientific and exploration mission, two Sorac 1.2 Plus class lasers were installed, along with suites of missile warning systems and glass bead emitters (for defense versus lasers), to demonstrate Earth's capacity for self-defense. Two former USAF sentry platform maintenance shuttles were mounted on the respective attachments bolted to the central fuel tank; they could only be crewed following a spacewalk from the command section, but they provided a means to approach natural bodies, such as asteroid belts of alien systems, without directly endangering the safety of the ship. Various optical and electronic telescopes were crammed into the various spaces of the main hull.

The ''Bonaventure'' first entered service with a three-month shakedown cruise outside the [[Sol]] system in [[2065]], before departing to [[Tau Ceti]] in [[2066]]. She was 206.1 meters in length, 63.4 meters wide, and 66.7 meters high (when the radiator was deployed in the open position). She massed about 79,400 metric tons. Her warp assemblies allowed for a speedy warp 2 for cruising, with a maximum speed of warp 2.5; her mission endurance was a very impressive six years. She was equipped with one general purpose laboratory, and one dedicated to planetary sciences. The ship's hull was mottled with hexagonal three-dimensional scanned telescopic arrays and one port-side electro-rigidized deployable radio antenna. Two (previously mentioned) shuttles were bolted to the ventral side of the central fuel tank and two shuttlepods for extravehicular maintenance were stored in the aft cargo bay of the command hull. The ship was crewed by 45 specialists with a gamut of areas of expertise and nations of origin.

The ''Bonaventure'' was not Earth's first ship to attempt a two-way interstellar journey, but she was the first to complete it, beating the three surviving pre-warp ''[[Guide:Columbus series|Columbus]]'' ships (''Icarus'', ''Hector'', and ''Prometheus'') home by about a decade, with her return from Tau Ceti. She would go missing on the third trip out, to [[Sirius]] in [[2077]], but not missing from her place in history.

==Missions==
* Mission [[2065]]: Three-month shakedown cruise outside the [[Sol]] system
* Mission [[2066]]: Exploration of the [[Tau Ceti]] system
* Mission [[2077]]: Exploration of the [[Sirius]] system (craft lost)

==Notes==
* The canon image of the ''Bonaventure'' (included in the gallery) is—unfortunately—not being used here, as it does appear to fall outside the design scope of both the article description and the lineage of early warp ships from [[Earth]]. I'd love to find a way to make it game-canon, maybe even as the described ''Seneca'', but because of the warp nacelles, it clearly is a post-2063 ship.

The late [[2060s]] saw a swift rebirth of industrial networks across and above the surface of the [[Earth]]. In consequence, the proliferation of warp technology and its adaptiveness to existing ship configurations enabled almost any organization with access to space to equip a warp-powered explorer. Literally hundreds of different ships exploded out of the solar system in search of new life, civilizations, raw materials, explanations and answers of all kinds – or just for the fun of it. The surviving governments of the time were determined to get their piece of the action as well, and in [[2073]], the first series-produced interstellar spaceship class, the '''''Verne''''' survey cruiser, was fielded to serve under the [[United Earth]] flag. The story of the ship class had begun much earlier, however, in the form of the final major nationalistic spacecraft program under [[NUN]] colors.

The original ''Verne'' ships were built jointly by the countries that had survived the devastation of [[WW III]] with the least damage – mainly the larger North American nations that were protected well enough, and South American and African nations not worthy of having been nuclear targets. They featured a hull taken from the promising ''[[Guide:Guardian (USAF)|Guardian]]'' series of [[USAF]] prewar near-Earth warships, a huge cone similar to the postwar ''[[Guide:Liberty|Liberty]]'' hulls yet technologically less ambitious and consequently more robust. Modifications to this design had been on the drawing boards for some time, and had held back prewar series production. Now these plans helped speed up the conversion of the ''Guardians'' into warp explorers that would give the West an edge over Terran competition.

In [[2064]], three ''Guardian'' hulls were available in orbit, but none were originally deemed salvageable. Instead, a completed but previously unlaunched hull lifted off from the reinstated [[Edwards Space Force Base]], bearing the name ''Jules Verne'' alongside its NUN livery. Launches of three flat, monoelement Korngold-McHale warp nacelles soon followed. These were mated to the aft hull at 120 degree intervals, not in the style of the Cochrane experiment but in the configuration of the USAF plans from the early [[2050s]]. A warp power source of three Singh-derived fusion reactors replaced half the fuel tankage as well as all the particle cannon from the original blueprints. As long planned, the fission NTR reaction engines from the late [[2040s]] were replaced by fusion NTR propulsion that utilized a single gigantic nozzle. Alterations to hull form were minimal, and did not attempt the kind of endurance increases the truly international ''[[Guide:Defiant and Valiant|Defiant/Valiant]]'' and ''[[Guide:Bonaventure (survey cruiser)|Bonaventure]]'' programs had aimed for. Instead, much of the original martial nature of the design survived. For example, the bow cone retained the original two missile tubes while gaining some protrusions necessitated by extended life support systems.

A successful sublight test flight in October [[2064]] paved way for the first warp run, initiated safely outside the orbit of [[Uranus]] on December 14th, [[2065]]. The ''Jules Verne'' reached warp 1.02 under the close supervision of a [[Vulcans|Vulcan]] chase ship. Never mind that the test run proved incorrect most of the USAF calculations, resulted in terminal damage to the nacelles, and was greeted by the Vulcans as "a most irresponsible and ill-advised act of experimentation", an apparent cussword in Vulcan science circles. Nor did the [[Sparon-DeSoto Treaty|Sparon-DeSoto]] clamp-on that squashed the original political goals of the program deter the participating nations. They still granted funding for the re-engining of the ''Verne'', completion of three more vessels out of unlaunched components, and conversion of the orbital derelicts to operational warp explorers.

By [[2075]], eighteen ''Vernes'' had been constructed, seventeen of them had attained warp capability, and sixteen had been launched on missions of exploration, to [[Epsilon Eridani]], [[Altair]], [[Arcturus]] and [[Sirius]]. In [[2073]], the nations operating the ''Verne'' ships promised to make all their findings public through the [[UESPA|UE Space Probe Agency]] (a promise only partially kept), and in [[2089]] relinquished control of their ships to the [[United Earth Stellar Navy|UE Stellar Navy]] (a more honest show of idealism). Little of this mattered to the ships and crews themselves, typically underway on decades-long journeys. Unlike the long-shot ''Defiant'' and ''Valiant'' missions, the ''Verne'' ships systematically surveyed the homeworlds of the newly encountered races and estimated their resources and military strength, charting nearby space for possible expansion. A top speed of warp 2.7 allowed the ships to outrun many private warp vessels
and thus to attain certain leverage over such entrepreneurs. The limited range of the ''Vernes'' often forced them to seek replenishment from the worlds they explored, leading to rudimentary trade agreements and improvised diplomatic overtures.

[[Image:Amity approaches Vulcan.png|left|300px|thumb|On the first [[Human]] diplomatic-scientific expedition to ''[[Vulcan|Vulcania]]'', ''USS Amity'' approaches 40 Eridani A, with the innermost planet of the system visible off port bow. The two orbit-to-surface craft, modified from Patriot transorbital interceptors, have already undocked; the photograph is taken from one of them, just prior to the craft engaging its rather formidable reaction drive for an independent rendezvous with planet Vulcan. The show-off maneuver was in fact necessitated by an embarrassing drive malfunction aboard the ''Amity'', leaving the mothership stranded on a circumstellar orbit. Vulcans were led to believe that the approach maneuver had ceremonial roots, while the crew of the ''Amity'' performed frantic and ultimately successful repairs.]]

Back on Earth, the ''Verne'' project initially faced stiff criticism from many nations struggling with the post-war horrors. Terrorist attacks frequently threatened the launches of components, and funding was hard to come by. But the rapid recovery of infrastructures in the [[2060s]] and [[2070s|70s]] made it possible to start fighting the rampant poverty and hunger and the environmental devastation. The recovery owed as much to the continuing space program as it owed to the Vulcan beneficiaries. Asteroid mining and weather and communications satellite networks were widely advertised as essential to Earth’s recuperation, and in the [[2070s|late 70s]] the public opinion had turned in favor of space exploration and exploitation. In the [[2080s|80s]], less than 20% of Earth’s population suffered from hunger and poverty—a feat never before attained. The remaining distress would disappear thanks to space resources and interstellar trade, promised the new world government.

The ''Verne'' ships frequently made the news with intriguing scientific discoveries and daring recovery operations of old sublight colonization ships. Dozens of colonies sprung up around distant stars and Earth’s solar system bustled with activity once again. But there were many setbacks in the space program as well. Most notably, it was found out that contacts with hostile alien cultures were quite possible, and that Earth would have to be ready for violent encounters. ''USS Mercury'' and ''USS Banshee'' were the first vessels of the class to be lost in deep space in [[2077]]. No official explanation was ever found for the losses, and the [[Vulcan High Command]] strongly discouraged such solo missions, at least until better communications networks would be in place. Existing Vulcan military networks were strictly off limits, however, presenting UESPA with a chicken-and-egg problem: contact with deep space explorers could only be maintained after extensive exploration of deep space.

On the other hand, nobody was left in the dark when ''USS Fletcher'' exploded and scattered debris to the upper atmosphere after a warp drive failure in Earth’s gravity well in [[2086]]. The early warp drives were notoriously unreliable anywhere near gravity gradients, and the three-lobed fields of the ''Vernes'' far more so than the Cochrane-style ones. Indeed, the ''Fletcher'' explosion factually spelled the end of the Korngold-McHale style of warp propulsion, leaving the Cochrane and Tellarite multicoil drives and the Vulcan ring-engine drive as the only serious competitors on the field. ''Verne'' vessels back in the [[Sol]] system at the time of the accident were assigned sublight duty and a destroyer designation, assisting the ''Liberty'' class in guarding Earth’s front yard against the next alien intrusion.

In [[2089]], ''USS Scythe'' briefly brought back to public view the ''Verne'' class for the last time as she accidentally fired her lasers at sister destroyer ''USS Hammer'' and the more modern ''USS Emnity'' in training maneuvers, resulting in significant casualties. The class was withdrawn from both combat and training use soon thereafter. No vessels of this type survive today, as the decommissioned destroyers were efficiently used for target practice.

==Notes==
* The original references to the UE Starfleet and [[Earth Fleet]] have been changed to [[United Earth Stellar Navy]], as the UESF was not founded until [[2133]]. Similarly, UESPA is made the target of the "chicken-and-egg problem", as [[2077]] was too early for the UESN's acquisition of the class.

* The infobox must still be updated with Timo's named ships (only). (Remove this when complete.)

* Aaaah: the [[2089]] transfer of the class to the UESN was due to the loss of the ''Fletcher'' in [[2086]], marking a mission change from exploration to defense.

==Background: ''The Hobbyist's Guide''==
The story of the dramatic rebirth of [[Earth]]’s spaceflight capability after [[WW III]] typically concentrates on three near-legendary elements: the warp breakthrough of [[2063]], the arrival of the staggeringly advanced [[Vulcans]] and their technological assistance, and the proliferation of peaceful Earth interstellar exploration and colonization vessels through refitting of prewar designs with warp drive. In surveys made throughout the [[23rd century|23rd]] and [[24th century|24th centuries]], well-educated Earth citizens frequently express the belief that all military space activity around Earth came to a halt with the destruction of the last active orbital weapon platforms in WW III, and that Earth’s defenses in the latter half of the [[21st century]] hinged on the presence of intimidatingly powerful Vulcan voidships. However, this belief has little basis in fact. As early as [[2058]], the [[United States of America]] was building its first postwar transorbital warships. And even though the global collapse of infrastructure slowed down the national re-escalation, by the late [[2060s]] the ''Liberty'' class system defense cruisers were Earth’s main line of defense against both interstellar intrusion and indigenous spatial conflict.

The ''Liberty'' ships were by most accounts very conservative vessels. These conical warships were built around fusion NTR engines with exhaust accelerators and petal-like radiator surfaces. Carrying plasma cannon, rockets, and fusion-tipped missiles, they were intended to fight enemies both large and small at close, medium and long insystem ranges alike. They could in theory reach one-third lightspeed at constant acceleration but lacked the fuel reserves, protective systems, and astrogation gear necessary for interstellar journeys. Yet they should not be mistaken for cheaply cobbled-together efforts by a dying civilization: the level of technology represented by the vessels is impressive by the standards of comparative interstellar history. From the very beginning, the ''Liberty'' program was intended to be the first step in [[Human]]ity’s reconquest of its native star system, and to rapidly surpass the achievements of the [[2000s]]-[[2040s]]. Had [[Zephram Cochrane]] not succeeded in his audacious private warp experiment – or had the [[USAF]] been able to proceed with the planned [[2055]] launch of its own ''WD-1'' faster-than-light test vehicle—Earth’s spaceflight history might have taken a very different form, with the ''Liberty'' class as its inspiration.

Fusion-powered NTR drive was made possible mainly through the perfection of compact reactors combining tokamak-style magnetic confinement and laser energizing. This form of fusion technology was ideal for spaceflight due to its low mass compared with reactors using combined magnetic confinement and energizing, or heavy e- or n-beam energizers. It did require large radiators to dissipate cyclically produced excess heat. In the ''Liberty'' design, the radiators were coupled with field guides for the exhaust accelerator system, forming a petal-like arrangement astern – an engineering solution peculiar to Earth, one out of many.

The rest of the defense cruiser was mundane engineering. Six biconical fuel/propellant tanks surrounded the reactor. Forward of a radiation shield, crew facilities featured standard zero-gee accommodation with provisions for ±2.5 g acceleration in standard flight mode. In combat mode, the crew would board liquid-filled acceleration stations, to allow the cruiser to perform 80 g maneuvers that would bring to bear the four steerable bow plasma cannon, the twin rocket launchers, or the long range fusion missile racks. Alternately, the enemy could be burned to cinder with the drive plume hundreds of thousands of kilometers long.

[[Image:Liberty arrives Ganymede.png|left|300px|thumb|Two sunrises on [[Ganymede]]. The drive plume of ''USS Liberty'' easily bests [[Sol]] in brightness, and nearly equals the radiation flux of [[Jupiter]] in deadliness, as the spacecraft establishes orbit around the moon and above the former mining colony. The ''Liberty'' vessels were not equipped for landing or carrying of orbit-to-surface auxiliaries, yet were elemental in re-establishing [[Human]] presence in the Jovian system and indirectly in bringing back online the mines and refineries. Bases around [[Saturn]] would have to wait a bit longer, being reactivated mainly with [[Vulcan]] help once Terran economies had stabilized in the early [[22nd century]].]]

The first ''Liberty'' ship gradually attained nominal drive capacity by [[2062]], but the USAF could not afford to perform an immediate test run due to the [[2060]] closing of the surviving [[White Sands]] spaceport and loss of heavy spacebus launch capacity. Construction crews did not finish orbital installation of armament until early [[2064]]. By that time, though, six new ''Liberty'' hulls had been launched to orbit for installation of systems, in a desperate bid to show teeth in front of the Vulcan expeditions. And by [[2070]], there were no fewer than 51 of these "baby teeth" in operation—but not in USAF hands. Vulcans had stepped in during the [[2065]] diplomatic expedition, and the Sparon-DeSoto Treaty that was forced upon the national militaries now dictated international crewing of all armed spacecraft within 5,000 AUs of [[Sol]].

The humblest of the visiting Vulcan vessels could naturally have blown the entire ''Liberty'' fleet out of the sky with minimal risk, had such an act of violence become necessary. But Vulcans insisted that the chances of a military confrontation within the [[Sol Transient Social Acclimatization Zone]] (far too intransient to the tastes of many a bitter Human) were less than 2.3% unless the Humans themselves provoked a crisis. Yet the Vulcans with their characteristic equanimity also insisted that there was no Vulcan blockade of the Sol system, and that visitors from the outside would be just as welcome to Sol as the Humans were free to leave the system.

True enough, in [[2073]] the remains of the pre-war defense net of Earth eventually detected an intruder: a small vessel of unknown configuration entered a [[Neptune|Neptunian]] approach corridor claimed by both [[Texas|Texan]] and [[Central African States|Central African]] gas mining corporations. A task force of ten ships led by the [[Nigeria]]n ADM [[Abel Niwen]], [[UESN]], aboard ''USS Bonhomme Richard'' of ''Liberty'' class intercepted the craft without waiting for orders from [[United Earth Space Central]], and enraging several nations. The remaining nuclear and biological missiles in their silos were readied, and for the last time in mankind’s history, the defense net stood by to explode unto itself, as soon as it was ascertained which nation was responsible for the intrusion. But to the astonishment of everybody, the ship turned out to be a somewhat lost alien explorer-merchantman carrying a crew of [[Tellarite]]s, a race contacted at their homeworld [[61 Cygni IV]] by warp surveyor ''SS Leif Eirickson'' only days before. As Earth studied the captured Tellarite ship, the radio transmissions of the ''Eirickson'' sped towards home to relay the news of the discovery, of the worldwide panic the "sneak attack" of the ''Eirickson'' had caused on [[Tellar]], and of the peaceful solution to that panic by the hand-and-hoofshake of Captain Anders and monarch [[Gartov]]. But the transmissions would not arrive for another [[2084|eleven years]], and the public was far more inclined to believe the rumors that hideous aliens were preparing for an invasion of Earth.

Despite the best efforts of doomsayers, no invasion force followed in the footsteps of the Tellarites. Nor did the Vulcans intervene in any manner military or diplomatic—an amazing degree of restraint that convinced most [[UE Defense Pact]] members that Earth still retained sovereign control of its star system and foreign relations. Disarmament of national militias, effectively stalled as a counter-reaction to the Sparon-DeSoto Treaty, now proceeded with vehemence and sincerity unimaginable back in the [[2060s]] or early [[2070s]]. In the end, the de-escalation also spelled the end of ''Liberty'' operations, and the large family of planned successor designs failed to materialize. A warp-powered successor did emerge, in the form of ''[[Guide: Verne|USS Jules Verne]]'' and her seventeen sisters, but this path proved a dead end as well.

By [[2087]], the remaining ''Liberty'' class vessels had been refitted with proper inertial damping. Following the establishment of the [[UESN Academy]] in [[2091]], they were employed primarily as training vessels. Built to embody a now-obsolete doctrine, the ships had little remaining operational value and were retired by [[2093]].

==Ships==
''Liberty'' class ships operating prior to the [[2069]] formation of the [[United Earth Stellar Navy]] had no prefixes, a continuation of the naming method used by the [[USAF]]. Once the ships were transferred into the UESN's rosters, they were assigned ''UES'' prefixes. USAF hull numbers (prefixed by CDH, for "heavy cruiser") were retained and applied to newbuilds.

* In order to not have the ''[[Guide: Columbus series|Columbus]]'' series craft as too fast (arriving at destinations pre-First Contact), all max speeds have been drastically reduced, (except for the DY-50).

* Timo's updated ''Guide'' replaced the ''Liberty''<nowiki>'</nowiki>s lasers with plasma cannon. However, the Construction Rules introduce those cannons in [[2106]], well past the class' operational period, so I'm leaving it with the lasers.''

* Admiral Niwen's service has been changed from [[UEDP]] to [[UESN]]. Additionally, the non-word "profilic" has been removed, as a proper context cannot be determined.

* In this article, Timo had the [[UEDP]] disbanded in [[2087]]; while SFC has it retain its existence as a unified [[Earth]] government until superseded by the formation of the [[United Earth]] government in [[2130]].

And by [[2070]], there were no fewer than 51 of these "baby teeth" in operation—but not in USAF hands. Vulcans had stepped in during the [[2065]] diplomatic expedition, and the Sparon-DeSoto Treaty that was forced upon the national militaries now dictated international crewing of all armed spacecraft within 5,000 AUs of [[Sol]].

The humblest of the visiting Vulcan vessels could naturally have blown the entire ''Liberty'' fleet out of the sky with minimal risk, had such an act of violence become necessary. But Vulcans insisted that the chances of a military confrontation within the [[Sol Transient Social Acclimatization Zone]] (far too intransient to the tastes of many a bitter Human) were less than 2.3% unless the Humans themselves provoked a crisis. Yet the Vulcans with their characteristic equanimity also insisted that there was no Vulcan blockade of the Sol system, and that visitors from the outside would be just as welcome to Sol as the Humans were free to leave the system.

True enough, in [[2073]] the remains of the pre-war defense net of Earth eventually detected an intruder: a small vessel of unknown configuration entered a [[Neptune|Neptunian]] approach corridor claimed by both [[Texas|Texan]] and [[Central African States|Central African]] gas mining corporations. A task force of ten ships led by the [[Nigeria]]n ADM [[Abel Niwen]], [[UESN]], aboard ''USS Bonhomme Richard'' of ''Liberty'' class intercepted the craft without waiting for orders from [[United Earth Space Central]], and enraging several nations. The remaining nuclear and biological missiles in their silos were readied, and for the last time in mankind’s history, the defense net stood by to explode unto itself, as soon as it was ascertained which nation was responsible for the intrusion. But to the astonishment of everybody, the ship turned out to be a somewhat lost alien explorer-merchantman carrying a crew of [[Tellarite]]s, a race contacted at their homeworld [[61 Cygni IV]] by warp surveyor ''SS Leif Eirickson'' only days before. As Earth studied the captured Tellarite ship, the radio transmissions of the ''Eirickson'' sped towards home to relay the news of the discovery, of the worldwide panic the "sneak attack" of the ''Eirickson'' had caused on [[Tellar]], and of the peaceful solution to that panic by the hand-and-hoofshake of Captain Anders and monarch [[Gartov]]. But the transmissions would not arrive for another [[2084|eleven years]], and the public was far more inclined to believe the rumors that hideous aliens were preparing for an invasion of Earth.

Despite the best efforts of doomsayers, no invasion force followed in the footsteps of the Tellarites. Nor did the Vulcans intervene in any manner military or diplomatic—an amazing degree of restraint that convinced most [[UE Defense Pact]] members that Earth still retained sovereign control of its star system and foreign relations. Disarmament of national militias, effectively stalled as a counter-reaction to the Sparon-DeSoto Treaty, now proceeded with vehemence and sincerity unimaginable back in the [[2060s]] or early [[2070s]]. In the end, the de-escalation also spelled the end of ''Liberty'' operations, and the large family of planned successor designs failed to materialize. A warp-powered successor did emerge, in the form of ''[[Guide: Verne|USS Jules Verne]]'' and her seventeen sisters, but this path proved a dead end as well.

By [[2087]], the remaining ''Liberty'' class vessels had been refitted with proper inertial damping. Following the establishment of the [[UESN Academy]] in [[2091]], they were employed primarily as training vessels. Built to embody a now-obsolete doctrine, the ships had little remaining operational value and were retired by [[2093]].

==Ships==
''Liberty'' class ships operating prior to the [[2069]] formation of the [[United Earth Stellar Navy]] had no prefixes, a continuation of the naming method used by the [[USAF]]. Once the ships were transferred into the UESN's rosters, they were assigned ''UES'' prefixes. USAF hull numbers (prefixed by CDH, for "heavy cruiser") were retained and applied to newbuilds.

==Notes==
* In order to not have the ''[[Guide: Columbus series|Columbus]]'' series craft as too fast (arriving at destinations pre-First Contact), all max speeds have been drastically reduced, (except for the DY-50).

* Timo's updated ''Guide'' replaced the ''Liberty''<nowiki>'</nowiki>s lasers with plasma cannon. However, the Construction Rules introduce those cannons in [[2106]], well past the class' operational period, so I'm leaving it with the lasers.''

* Admiral Niwen's service has been changed from [[UEDP]] to [[UESN]]. Additionally, the non-word "profilic" has been removed, as a proper context cannot be determined.

* In this article, Timo had the [[UEDP]] disbanded in [[2087]]; while SFC has it retain its existence as a unified [[Earth]] government until superseded by the formation of the [[United Earth]] government in [[2130]].

Dan: /* 8.9 Sensor Systems */

__toc__
==8.9 Sensor Systems==
Sensors are a starship’s “eyes”. They allow it to detect not only phenomena visible to humanoid sight, but an enormous number of electromagnetic and physical phenomena which humanoid senses cannot perceive. Every starship has many different types of sensors (Explorers, Scouts, and Research/Laboratory vessels tend to have more or better sensors, for obvious reasons), divided into four types: long-range; lateral (or short-range); navigation; and specialized. Sensors are rated for three characteristics: the '''range''' over which they work accurately; their “'''gain'''”, or efficiency relative to their power input (represented in game terms as a bonus to Shipboard Systems (Sensors) Test Results); and their '''strength''', or ability to overcome interference.

Caveat: Standard Star Fleet sensor technology, as extremely sensitive as it is, does not detect some 15,000 substances. The regular sensor settings do not include certain unusual, rare, and/or exotic materials. It excludes these from the standard analysis routines because they occur so infrequently that it’s inefficient to search for them all the time. Crewmembers can re-calibrate sensors to detect many of these substances, but this usually requires them to “blind” the sensors to something they normally register. Detecting the other types of exotic particles requires special sensor equipment and/or analysis programming.

'''Active and Passive Sensing''' 
An important distinction between different types of scans involves active versus passive sensor use. Active scans require the ship to project some form of energy, then read what happens to that energy (how it reflects back to the ship or dissipates) to locate and track objects and phenomena. Active scanning gives a ship control over what it’s detecting (or trying to), but reveals the ship’s position to other ships. Passive scans, on the other hand, involve receiving and analyzing forms of energy or other phenomena which come to the ship on their own—the energy projected by a star, for example. Ships have less control over what a passive scan can detect (if the target of the scan is not emitting any radiation, the ship can’t perceive it), but don’t run the risk of detection just for sitting there with their “eyes and ears” open.

Active sensor scan pulses typically travel at Warp 9.9997. At this speed, it takes about 45 minutes to perform a long-range scan at 17 light-years.

''House rule:'' Use the long-range package’s listed high- and low-resolution range bands for either active or passive sensing. Passive detection requires suitable emissions from the target to reach the receiver; being within a listed range does not itself make the target detectable. For the Starship Tracker app, this means the Passive Range value matches the Active Range.

'''Exceeding a Sensor's Range''' 
All sensors have a maximum effective range. For ease of game play, it is assumed that beyond that range, a sensor’s effects or readings become so attenuated or vague or contradictory that they’re useless. If they prefer, Narrators may instead impose substantial Test Result penalties for scans beyond a sensor’s maximum range: -5 for every 0.25 light-years beyond maximum for long-range sensors; -20 or greater for other sensors. The further beyond the sensor’s range an object is, the greater the penalty to Tests made to detect it, and the more vague the data recovered.

===8.9.1 Long-Range Sensors===
'''(Required)''' 
'''Cost:''' Varies (see tables) 
'''Power Requirement:''' 5 Power per round of use; ''1 for pre-subspace sensors''

The long-range sensors, located in a series of eight instrument bays behind the deflector dish, include narrow- and wide-angle active electromagnetic scanners, a parametric subspace field stress sensor, a gravimetric distortion scanner, a variable frequency electromagnetic flux sensor, a lifeform analysis instrument cluster, a passive neutrino imaging scanner, a thermal imaging array, and a (2+ meter) gamma-ray telescope.

Long-range sensors usually involve active scanning. They work better at high resolution (+10% to Crew Skill Test Results), but this limits their range to five light-years (as of [[2273]]). Their maximum range (at medium-to-low resolution) is typically in the 14-17 light-year range. The arc of detection is usually about 45 degrees in front of the ship, though this narrows slightly at longer ranges.

Beginning in [[2271]], significant advances in sensor technology, coupled with similar advances with navigational deflectors, offered dramatic leaps in effective capabilities and the nomenclature system was altered to reflect the changes.

'''Coverage:''' Standard ship sensors cannot detect about 15,000 substances and effects unless they’re calibrated for them. However, a ship can reduce this number by -1,000 substances for every 3 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). ''TOS''-era ships using the Mark series cannot detect about 23,000 substances and effects unless they’re calibrated for them. However, it can reduce this number by -1,000 substances for every +4 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). See '''Table 8.9.1d: Sensor Coverage''' for specific coverage exclusion ranges.

The accompanying table indicates the range, gain, strength, and SU cost for long-range sensor packages. Range includes '''Point Blank, Short, Medium''', and '''Long''' for high and low resolution use of the sensors (high resolution provides a better “picture” and more information). The base Difficulties to detect an object at those ranges are 97 / 92 / 58 / 17 ''(for the Mark series: 92 / 83 / 42 / 8)'', respectively, and are enhanced by the Strength Package. Many circumstances (interference, the size or quality of the target, and so forth) may modify this Difficulty. (If the rules give a standard Difficulty for performing a task with sensors, such as detecting a cloaked ship, use that Difficulty or the Difficulty for range, whichever is higher.) For every 0.25 light-year beyond Long range, increase the Difficulty to detect a target by -10%.

'''Note:''' The Pre-Warp long-range sensors have been replaced by Pre-Subspace sensors that operate via radiated energy limited to the speed of light. Based on my calculations, a sensor system that predates the use of subspace for detection would have a maximum effective range of approximately 407,000 kilometers. This assumes a 45-minute round-trip signal time: 22.5 minutes for the emitted signal to reach the target and another 22.5 minutes for the return signal to reach the originating vessel, the time allowed for a long-range scan conducted by modern subspace sensors. The base Difficulties to detect an object at those ranges are 72 / 58 / 17 / -.

===8.9.2 Lateral Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Lateral Sensors - Strength table); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Lateral sensors, so called because their sensor pallets are usually located along the edges or sides of various parts of a ship, are short range systems which can detect a wide range of phenomena from any direction around the ship. The individual sensor pallets are located all over the ship’s hull to maximize signal gain and system flexibility, and to provide redundancy in case some pallets are damaged. On most starships, standard Star Fleet sensor packages occupy the majority of a ship’s lateral sensor pallets, but the remainder are open for mission-specific sensor packages. The standard Star Fleet science sensor array consists of six pallets, each containing one to six specific sensory devices, which include the following:

* Pallet #1
** wide-angle EM radiation imaging scanner
** quark population analysis counter
** Z-range particulate spectrometry sensor

* Pallet #2
** high-energy proton spectrometry cluster
** gravimetric distortion mapping scanner

* Pallet #3
** steerable lifeform analysis instrument cluster

* Pallet #4
** active magnetic interferometry scanner
** low-frequency EM flux sensor
** localized subspace field stress sensor
** parametric subspace field stress sensor
** hydrogen-filter subspace flux scanner
** linear calibration subspace flux sensor

* Pallet #5
** variable band optical imaging cluster
** virtual aperture graviton flux spectrometer
** high-resolution graviton flux spectrometer
** very low energy graviton spin polarimeter

* Pallet #6
** passive imaging gamma interferometry sensor
** low-level thermal imaging sensor
** fixed angle gamma frequency counter
** virtual particle mapping camera

Lateral sensors are both active and passive. Among their many uses, they are employed extensively in combat situations to monitor enemy movement and activities. Their maximum active range is approximately one light-year; for every 0.25 light-year beyond maximum range, increase the Difficulty by -20. Their gain depends on the gain package taken (see table). The SU cost for the gain package adds to the base cost of the lateral sensors, as indicated by the '''Lateral Sensors - Strength''' table.
----
'''Planetary Facility''': The general (non-scientific) sensors installed on a planetary facility are rather similar to the ones that comprise a ship's lateral sensors. A facility may also have long-range sensors or scientific ones, depending on its mission.

===8.9.3 Navigational Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Navigational Sensors - Strength tables); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Navigational sensors, which help the flight control officer steer the ship in the proper direction and avoid space debris, include a quasar telescope, passive subspace multibeacon receivers, stellar graviton detectors, a Federation timebase beacon receiver, wide-angle IR source tracker, narrow-angle IR-UV-gamma ray imager, high-energy charged particle detectors, galactic plasma wave cartographic processor, and stellar pair coordinate imager. The ship’s guidance and navigation (G&N) relay handles the flow of sensor data and converts it into usable information with three- and four-dimensional flight motion software which feeds directly into the flight control system.

The accompanying table indicates the strength, gain, and SU cost of navigational sensors. The gain bonus applies to Shipboard Systems (Sensors) or (Flight Control) Tests to detect an object in a vessel’s flight path, determine where the starship is located, chart a course, or the like.

__toc__
==8.9 Sensor Systems==
Sensors are a starship’s “eyes”. They allow it to detect not only phenomena visible to humanoid sight, but an enormous number of electromagnetic and physical phenomena which humanoid senses cannot perceive. Every starship has many different types of sensors (Explorers, Scouts, and Research/Laboratory vessels tend to have more or better sensors, for obvious reasons), divided into four types: long-range; lateral (or short-range); navigation; and specialized. Sensors are rated for three characteristics: the '''range''' over which they work accurately; their “'''gain'''”, or efficiency relative to their power input (represented in game terms as a bonus to Shipboard Systems (Sensors) Test Results); and their '''strength''', or ability to overcome interference.

Caveat: Standard Star Fleet sensor technology, as extremely sensitive as it is, does not detect some 15,000 substances. The regular sensor settings do not include certain unusual, rare, and/or exotic materials. It excludes these from the standard analysis routines because they occur so infrequently that it’s inefficient to search for them all the time. Crewmembers can re-calibrate sensors to detect many of these substances, but this usually requires them to “blind” the sensors to something they normally register. Detecting the other types of exotic particles requires special sensor equipment and/or analysis programming.

'''Active and Passive Sensing''' 
An important distinction between different types of scans involves active versus passive sensor use. Active scans require the ship to project some form of energy, then read what happens to that energy (how it reflects back to the ship or dissipates) to locate and track objects and phenomena. Active scanning gives a ship control over what it’s detecting (or trying to), but reveals the ship’s position to other ships. Passive scans, on the other hand, involve receiving and analyzing forms of energy or other phenomena which come to the ship on their own—the energy projected by a star, for example. Ships have less control over what a passive scan can detect (if the target of the scan is not emitting any radiation, the ship can’t perceive it), but don’t run the risk of detection just for sitting there with their “eyes and ears” open.

Active sensor scan pulses typically travel at Warp 9.9997. At this speed, it takes about 45 minutes to perform a long-range scan at 17 light-years.

''House rule:'' Use the long-range package’s listed high- and low-resolution range bands for either active or passive sensing. Passive detection requires suitable emissions from the target to reach the receiver; being within a listed range does not itself make the target detectable.

'''Exceeding a Sensor's Range''' 
All sensors have a maximum effective range. For ease of game play, it is assumed that beyond that range, a sensor’s effects or readings become so attenuated or vague or contradictory that they’re useless. If they prefer, Narrators may instead impose substantial Test Result penalties for scans beyond a sensor’s maximum range: -5 for every 0.25 light-years beyond maximum for long-range sensors; -20 or greater for other sensors. The further beyond the sensor’s range an object is, the greater the penalty to Tests made to detect it, and the more vague the data recovered.

===8.9.1 Long-Range Sensors===
'''(Required)''' 
'''Cost:''' Varies (see tables) 
'''Power Requirement:''' 5 Power per round of use; ''1 for pre-subspace sensors''

The long-range sensors, located in a series of eight instrument bays behind the deflector dish, include narrow- and wide-angle active electromagnetic scanners, a parametric subspace field stress sensor, a gravimetric distortion scanner, a variable frequency electromagnetic flux sensor, a lifeform analysis instrument cluster, a passive neutrino imaging scanner, a thermal imaging array, and a (2+ meter) gamma-ray telescope.

Long-range sensors usually involve active scanning. They work better at high resolution (+10% to Crew Skill Test Results), but this limits their range to five light-years (as of [[2273]]). Their maximum range (at medium-to-low resolution) is typically in the 14-17 light-year range. The arc of detection is usually about 45 degrees in front of the ship, though this narrows slightly at longer ranges.

Beginning in [[2271]], significant advances in sensor technology, coupled with similar advances with navigational deflectors, offered dramatic leaps in effective capabilities and the nomenclature system was altered to reflect the changes.

'''Coverage:''' Standard ship sensors cannot detect about 15,000 substances and effects unless they’re calibrated for them. However, a ship can reduce this number by -1,000 substances for every 3 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). ''TOS''-era ships using the Mark series cannot detect about 23,000 substances and effects unless they’re calibrated for them. However, it can reduce this number by -1,000 substances for every +4 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). See '''Table 8.9.1d: Sensor Coverage''' for specific coverage exclusion ranges.

The accompanying table indicates the range, gain, strength, and SU cost for long-range sensor packages. Range includes '''Point Blank, Short, Medium''', and '''Long''' for high and low resolution use of the sensors (high resolution provides a better “picture” and more information). The base Difficulties to detect an object at those ranges are 97 / 92 / 58 / 17 ''(for the Mark series: 92 / 83 / 42 / 8)'', respectively, and are enhanced by the Strength Package. Many circumstances (interference, the size or quality of the target, and so forth) may modify this Difficulty. (If the rules give a standard Difficulty for performing a task with sensors, such as detecting a cloaked ship, use that Difficulty or the Difficulty for range, whichever is higher.) For every 0.25 light-year beyond Long range, increase the Difficulty to detect a target by -10%.

'''Note:''' The Pre-Warp long-range sensors have been replaced by Pre-Subspace sensors that operate via radiated energy limited to the speed of light. Based on my calculations, a sensor system that predates the use of subspace for detection would have a maximum effective range of approximately 407,000 kilometers. This assumes a 45-minute round-trip signal time: 22.5 minutes for the emitted signal to reach the target and another 22.5 minutes for the return signal to reach the originating vessel, the time allowed for a long-range scan conducted by modern subspace sensors. The base Difficulties to detect an object at those ranges are 72 / 58 / 17 / -.

===8.9.2 Lateral Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Lateral Sensors - Strength table); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Lateral sensors, so called because their sensor pallets are usually located along the edges or sides of various parts of a ship, are short range systems which can detect a wide range of phenomena from any direction around the ship. The individual sensor pallets are located all over the ship’s hull to maximize signal gain and system flexibility, and to provide redundancy in case some pallets are damaged. On most starships, standard Star Fleet sensor packages occupy the majority of a ship’s lateral sensor pallets, but the remainder are open for mission-specific sensor packages. The standard Star Fleet science sensor array consists of six pallets, each containing one to six specific sensory devices, which include the following:

* Pallet #1
** wide-angle EM radiation imaging scanner
** quark population analysis counter
** Z-range particulate spectrometry sensor

* Pallet #2
** high-energy proton spectrometry cluster
** gravimetric distortion mapping scanner

* Pallet #3
** steerable lifeform analysis instrument cluster

* Pallet #4
** active magnetic interferometry scanner
** low-frequency EM flux sensor
** localized subspace field stress sensor
** parametric subspace field stress sensor
** hydrogen-filter subspace flux scanner
** linear calibration subspace flux sensor

* Pallet #5
** variable band optical imaging cluster
** virtual aperture graviton flux spectrometer
** high-resolution graviton flux spectrometer
** very low energy graviton spin polarimeter

* Pallet #6
** passive imaging gamma interferometry sensor
** low-level thermal imaging sensor
** fixed angle gamma frequency counter
** virtual particle mapping camera

Lateral sensors are both active and passive. Among their many uses, they are employed extensively in combat situations to monitor enemy movement and activities. Their maximum active range is approximately one light-year; for every 0.25 light-year beyond maximum range, increase the Difficulty by -20. Their gain depends on the gain package taken (see table). The SU cost for the gain package adds to the base cost of the lateral sensors, as indicated by the '''Lateral Sensors - Strength''' table.
----
'''Planetary Facility''': The general (non-scientific) sensors installed on a planetary facility are rather similar to the ones that comprise a ship's lateral sensors. A facility may also have long-range sensors or scientific ones, depending on its mission.

===8.9.3 Navigational Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Navigational Sensors - Strength tables); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Navigational sensors, which help the flight control officer steer the ship in the proper direction and avoid space debris, include a quasar telescope, passive subspace multibeacon receivers, stellar graviton detectors, a Federation timebase beacon receiver, wide-angle IR source tracker, narrow-angle IR-UV-gamma ray imager, high-energy charged particle detectors, galactic plasma wave cartographic processor, and stellar pair coordinate imager. The ship’s guidance and navigation (G&N) relay handles the flow of sensor data and converts it into usable information with three- and four-dimensional flight motion software which feeds directly into the flight control system.

The accompanying table indicates the strength, gain, and SU cost of navigational sensors. The gain bonus applies to Shipboard Systems (Sensors) or (Flight Control) Tests to detect an object in a vessel’s flight path, determine where the starship is located, chart a course, or the like.

Dan: /* 8.9.2 Lateral Sensors */

__toc__
==8.9 Sensor Systems==
Sensors are a starship’s “eyes”. They allow it to detect not only phenomena visible to humanoid sight, but an enormous number of electromagnetic and physical phenomena which humanoid senses cannot perceive. Every starship has many different types of sensors (Explorers, Scouts, and Research/Laboratory vessels tend to have more or better sensors, for obvious reasons), divided into four types: long-range; lateral (or short-range); navigation; and specialized. Sensors are rated for three characteristics: the '''range''' over which they work accurately; their “'''gain'''”, or efficiency relative to their power input (represented in game terms as a bonus to Shipboard Systems (Sensors) Test Results); and their '''strength''', or ability to overcome interference.

Caveat: Standard Star Fleet sensor technology, as extremely sensitive as it is, does not detect some 15,000 substances. The regular sensor settings do not include certain unusual, rare, and/or exotic materials. It excludes these from the standard analysis routines because they occur so infrequently that it’s inefficient to search for them all the time. Crewmembers can re-calibrate sensors to detect many of these substances, but this usually requires them to “blind” the sensors to something they normally register. Detecting the other types of exotic particles requires special sensor equipment and/or analysis programming.

'''Active and Passive Sensing''' 
An important distinction between different types of scans involves active versus passive sensor use. Active scans require the ship to project some form of energy, then read what happens to that energy (how it reflects back to the ship or dissipates) to locate and track objects and phenomena. Active scanning gives a ship control over what it’s detecting (or trying to), but reveals the ship’s position to other ships. Passive scans, on the other hand, involve receiving and analyzing forms of energy or other phenomena which come to the ship on their own—the energy projected by a star, for example. Ships have less control over what a passive scan can detect (if the target of the scan is not emitting any radiation, the ship can’t perceive it), but don’t run the risk of detection just for sitting there with their “eyes and ears” open.

Active sensor scan pulses typically travel at Warp 9.9997. At this speed, it takes about 45 minutes to perform a long-range scan at 17 light-years.

'''Exceeding a Sensor's Range''' 
All sensors have a maximum effective range. For ease of game play, it is assumed that beyond that range, a sensor’s effects or readings become so attenuated or vague or contradictory that they’re useless. If they prefer, Narrators may instead impose substantial Test Result penalties for scans beyond a sensor’s maximum range: -5 for every 0.25 light-years beyond maximum for long-range sensors; -20 or greater for other sensors. The further beyond the sensor’s range an object is, the greater the penalty to Tests made to detect it, and the more vague the data recovered.

===8.9.1 Long-Range Sensors===
'''(Required)''' 
'''Cost:''' Varies (see tables) 
'''Power Requirement:''' 5 Power per round of use; ''1 for pre-subspace sensors''

The long-range sensors, located in a series of eight instrument bays behind the deflector dish, include narrow- and wide-angle active electromagnetic scanners, a parametric subspace field stress sensor, a gravimetric distortion scanner, a variable frequency electromagnetic flux sensor, a lifeform analysis instrument cluster, a passive neutrino imaging scanner, a thermal imaging array, and a (2+ meter) gamma-ray telescope.

Long-range sensors usually involve active scanning. They work better at high resolution (+10% to Crew Skill Test Results), but this limits their range to five light-years (as of [[2273]]). Their maximum range (at medium-to-low resolution) is typically in the 14-17 light-year range. The arc of detection is usually about 45 degrees in front of the ship, though this narrows slightly at longer ranges.

Beginning in [[2271]], significant advances in sensor technology, coupled with similar advances with navigational deflectors, offered dramatic leaps in effective capabilities and the nomenclature system was altered to reflect the changes.

'''Coverage:''' Standard ship sensors cannot detect about 15,000 substances and effects unless they’re calibrated for them. However, a ship can reduce this number by -1,000 substances for every 3 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). ''TOS''-era ships using the Mark series cannot detect about 23,000 substances and effects unless they’re calibrated for them. However, it can reduce this number by -1,000 substances for every +4 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). See '''Table 8.9.1d: Sensor Coverage''' for specific coverage exclusion ranges.

The accompanying table indicates the range, gain, strength, and SU cost for long-range sensor packages. Range includes '''Point Blank, Short, Medium''', and '''Long''' for high and low resolution use of the sensors (high resolution provides a better “picture” and more information). The base Difficulties to detect an object at those ranges are 97 / 92 / 58 / 17 ''(for the Mark series: 92 / 83 / 42 / 8)'', respectively, and are enhanced by the Strength Package. Many circumstances (interference, the size or quality of the target, and so forth) may modify this Difficulty. (If the rules give a standard Difficulty for performing a task with sensors, such as detecting a cloaked ship, use that Difficulty or the Difficulty for range, whichever is higher.) For every 0.25 light-year beyond Long range, increase the Difficulty to detect a target by -10%.

'''Note:''' The Pre-Warp long-range sensors have been replaced by Pre-Subspace sensors that operate via radiated energy limited to the speed of light. Based on my calculations, a sensor system that predates the use of subspace for detection would have a maximum effective range of approximately 407,000 kilometers. This assumes a 45-minute round-trip signal time: 22.5 minutes for the emitted signal to reach the target and another 22.5 minutes for the return signal to reach the originating vessel, the time allowed for a long-range scan conducted by modern subspace sensors. The base Difficulties to detect an object at those ranges are 72 / 58 / 17 / -.

===8.9.2 Lateral Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Lateral Sensors - Strength table); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Lateral sensors, so called because their sensor pallets are usually located along the edges or sides of various parts of a ship, are short range systems which can detect a wide range of phenomena from any direction around the ship. The individual sensor pallets are located all over the ship’s hull to maximize signal gain and system flexibility, and to provide redundancy in case some pallets are damaged. On most starships, standard Star Fleet sensor packages occupy the majority of a ship’s lateral sensor pallets, but the remainder are open for mission-specific sensor packages. The standard Star Fleet science sensor array consists of six pallets, each containing one to six specific sensory devices, which include the following:

* Pallet #1
** wide-angle EM radiation imaging scanner
** quark population analysis counter
** Z-range particulate spectrometry sensor

* Pallet #2
** high-energy proton spectrometry cluster
** gravimetric distortion mapping scanner

* Pallet #3
** steerable lifeform analysis instrument cluster

* Pallet #4
** active magnetic interferometry scanner
** low-frequency EM flux sensor
** localized subspace field stress sensor
** parametric subspace field stress sensor
** hydrogen-filter subspace flux scanner
** linear calibration subspace flux sensor

* Pallet #5
** variable band optical imaging cluster
** virtual aperture graviton flux spectrometer
** high-resolution graviton flux spectrometer
** very low energy graviton spin polarimeter

* Pallet #6
** passive imaging gamma interferometry sensor
** low-level thermal imaging sensor
** fixed angle gamma frequency counter
** virtual particle mapping camera

Lateral sensors are both active and passive. Among their many uses, they are employed extensively in combat situations to monitor enemy movement and activities. Their maximum active range is approximately one light-year; for every 0.25 light-year beyond maximum range, increase the Difficulty by -20. Their gain depends on the gain package taken (see table). The SU cost for the gain package adds to the base cost of the lateral sensors, as indicated by the '''Lateral Sensors - Strength''' table.
----
'''Planetary Facility''': The general (non-scientific) sensors installed on a planetary facility are rather similar to the ones that comprise a ship's lateral sensors. A facility may also have long-range sensors or scientific ones, depending on its mission.

===8.9.3 Navigational Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Navigational Sensors - Strength tables); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Navigational sensors, which help the flight control officer steer the ship in the proper direction and avoid space debris, include a quasar telescope, passive subspace multibeacon receivers, stellar graviton detectors, a Federation timebase beacon receiver, wide-angle IR source tracker, narrow-angle IR-UV-gamma ray imager, high-energy charged particle detectors, galactic plasma wave cartographic processor, and stellar pair coordinate imager. The ship’s guidance and navigation (G&N) relay handles the flow of sensor data and converts it into usable information with three- and four-dimensional flight motion software which feeds directly into the flight control system.

The accompanying table indicates the strength, gain, and SU cost of navigational sensors. The gain bonus applies to Shipboard Systems (Sensors) or (Flight Control) Tests to detect an object in a vessel’s flight path, determine where the starship is located, chart a course, or the like.

Dan: /* 8.9.2 Lateral Sensors */

__toc__
==8.9 Sensor Systems==
Sensors are a starship’s “eyes”. They allow it to detect not only phenomena visible to humanoid sight, but an enormous number of electromagnetic and physical phenomena which humanoid senses cannot perceive. Every starship has many different types of sensors (Explorers, Scouts, and Research/Laboratory vessels tend to have more or better sensors, for obvious reasons), divided into four types: long-range; lateral (or short-range); navigation; and specialized. Sensors are rated for three characteristics: the '''range''' over which they work accurately; their “'''gain'''”, or efficiency relative to their power input (represented in game terms as a bonus to Shipboard Systems (Sensors) Test Results); and their '''strength''', or ability to overcome interference.

Caveat: Standard Star Fleet sensor technology, as extremely sensitive as it is, does not detect some 15,000 substances. The regular sensor settings do not include certain unusual, rare, and/or exotic materials. It excludes these from the standard analysis routines because they occur so infrequently that it’s inefficient to search for them all the time. Crewmembers can re-calibrate sensors to detect many of these substances, but this usually requires them to “blind” the sensors to something they normally register. Detecting the other types of exotic particles requires special sensor equipment and/or analysis programming.

'''Active and Passive Sensing''' 
An important distinction between different types of scans involves active versus passive sensor use. Active scans require the ship to project some form of energy, then read what happens to that energy (how it reflects back to the ship or dissipates) to locate and track objects and phenomena. Active scanning gives a ship control over what it’s detecting (or trying to), but reveals the ship’s position to other ships. Passive scans, on the other hand, involve receiving and analyzing forms of energy or other phenomena which come to the ship on their own—the energy projected by a star, for example. Ships have less control over what a passive scan can detect (if the target of the scan is not emitting any radiation, the ship can’t perceive it), but don’t run the risk of detection just for sitting there with their “eyes and ears” open.

Active sensor scan pulses typically travel at Warp 9.9997. At this speed, it takes about 45 minutes to perform a long-range scan at 17 light-years.

'''Exceeding a Sensor's Range''' 
All sensors have a maximum effective range. For ease of game play, it is assumed that beyond that range, a sensor’s effects or readings become so attenuated or vague or contradictory that they’re useless. If they prefer, Narrators may instead impose substantial Test Result penalties for scans beyond a sensor’s maximum range: -5 for every 0.25 light-years beyond maximum for long-range sensors; -20 or greater for other sensors. The further beyond the sensor’s range an object is, the greater the penalty to Tests made to detect it, and the more vague the data recovered.

===8.9.1 Long-Range Sensors===
'''(Required)''' 
'''Cost:''' Varies (see tables) 
'''Power Requirement:''' 5 Power per round of use; ''1 for pre-subspace sensors''

The long-range sensors, located in a series of eight instrument bays behind the deflector dish, include narrow- and wide-angle active electromagnetic scanners, a parametric subspace field stress sensor, a gravimetric distortion scanner, a variable frequency electromagnetic flux sensor, a lifeform analysis instrument cluster, a passive neutrino imaging scanner, a thermal imaging array, and a (2+ meter) gamma-ray telescope.

Long-range sensors usually involve active scanning. They work better at high resolution (+10% to Crew Skill Test Results), but this limits their range to five light-years (as of [[2273]]). Their maximum range (at medium-to-low resolution) is typically in the 14-17 light-year range. The arc of detection is usually about 45 degrees in front of the ship, though this narrows slightly at longer ranges.

Beginning in [[2271]], significant advances in sensor technology, coupled with similar advances with navigational deflectors, offered dramatic leaps in effective capabilities and the nomenclature system was altered to reflect the changes.

'''Coverage:''' Standard ship sensors cannot detect about 15,000 substances and effects unless they’re calibrated for them. However, a ship can reduce this number by -1,000 substances for every 3 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). ''TOS''-era ships using the Mark series cannot detect about 23,000 substances and effects unless they’re calibrated for them. However, it can reduce this number by -1,000 substances for every +4 SUs (thus making its sensors better), or increase it +1,000 substances for every -2 SUs (thus making them worse). See '''Table 8.9.1d: Sensor Coverage''' for specific coverage exclusion ranges.

The accompanying table indicates the range, gain, strength, and SU cost for long-range sensor packages. Range includes '''Point Blank, Short, Medium''', and '''Long''' for high and low resolution use of the sensors (high resolution provides a better “picture” and more information). The base Difficulties to detect an object at those ranges are 97 / 92 / 58 / 17 ''(for the Mark series: 92 / 83 / 42 / 8)'', respectively, and are enhanced by the Strength Package. Many circumstances (interference, the size or quality of the target, and so forth) may modify this Difficulty. (If the rules give a standard Difficulty for performing a task with sensors, such as detecting a cloaked ship, use that Difficulty or the Difficulty for range, whichever is higher.) For every 0.25 light-year beyond Long range, increase the Difficulty to detect a target by -10%.

'''Note:''' The Pre-Warp long-range sensors have been replaced by Pre-Subspace sensors that operate via radiated energy limited to the speed of light. Based on my calculations, a sensor system that predates the use of subspace for detection would have a maximum effective range of approximately 407,000 kilometers. This assumes a 45-minute round-trip signal time: 22.5 minutes for the emitted signal to reach the target and another 22.5 minutes for the return signal to reach the originating vessel, the time allowed for a long-range scan conducted by modern subspace sensors. The base Difficulties to detect an object at those ranges are 72 / 58 / 17 / -.

===8.9.2 Lateral Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Lateral Sensors - Strength table); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Lateral sensors, so called because their sensor pallets are usually located along the edges or sides of various parts of a ship, are short range systems which can detect a wide range of phenomena from any direction around the ship. The individual sensor pallets are located all over the ship’s hull to maximize signal gain and system flexibility, and to provide redundancy in case some pallets are damaged. On most starships, standard Star Fleet sensor packages occupy the majority of a ship’s lateral sensor pallets, but the remainder are open for mission-specific sensor packages. The standard Star Fleet science sensor array consists of six pallets, each containing one to six specific sensory devices, which include the following:

* Pallet #1
** wide-angle EM radiation imaging scanner
** quark population analysis counter
** Z-range particulate spectrometry sensor

* Pallet #2
** high-energy proton spectrometry cluster
** gravimetric distortion mapping scanner

* Pallet #3
** steerable lifeform analysis instrument cluster

* Pallet #4
** active magnetic interferometry scanner
** low-frequency EM flux sensor
** localized subspace field stress sensor
** parametric subspace field stress sensor
** hydrogen-filter subspace flux scanner
** linear calibration subspace flux sensor

* Pallet #5
** variable band optical imaging cluster
** virtual aperture graviton flux spectrometer
** high-resolution graviton flux spectrometer
** very low energy graviton spin polarimeter

* Pallet #6
** passive imaging gamma interferometry sensor
** low-level thermal imaging sensor
** fixed angle gamma frequency counter
** virtual particle mapping camera

Lateral sensors are both active and passive. Among their many uses, they are employed extensively in combat situations to monitor enemy movement and activities. Their maximum active range is approximately one light-year; for every 0.25 light-year beyond maximum range, increase the Difficulty by -20. Their gain depends on the gain package taken (see table). The SU cost for the gain package adds to the base cost of the lateral sensors.
----
'''Planetary Facility''': The general (non-scientific) sensors installed on a planetary facility are rather similar to the ones that comprise a ship's lateral sensors. A facility may also have long-range sensors or scientific ones, depending on its mission.

===8.9.3 Navigational Sensors===
'''(Required)''' 
'''Cost:''' Varies (see Navigational Sensors - Strength tables); gain additions add to cost 
'''Power Requirement:''' 5 Power per round of use; 1 for pre-subspace sensors

Navigational sensors, which help the flight control officer steer the ship in the proper direction and avoid space debris, include a quasar telescope, passive subspace multibeacon receivers, stellar graviton detectors, a Federation timebase beacon receiver, wide-angle IR source tracker, narrow-angle IR-UV-gamma ray imager, high-energy charged particle detectors, galactic plasma wave cartographic processor, and stellar pair coordinate imager. The ship’s guidance and navigation (G&N) relay handles the flow of sensor data and converts it into usable information with three- and four-dimensional flight motion software which feeds directly into the flight control system.

The accompanying table indicates the strength, gain, and SU cost of navigational sensors. The gain bonus applies to Shipboard Systems (Sensors) or (Flight Control) Tests to detect an object in a vessel’s flight path, determine where the starship is located, chart a course, or the like.

Build:Warp Propulsion System

2026-10-11T10:01:32Z

Dan: /* Recovery from maximum warp */

__toc__
==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Operating between Sustainable and Maximum speeds====
: '''''Note:''' this is a house rule.''

For endurance, recovery, and overrun damage purposes, operation at any speed above Sustainable warp counts as operation at Maximum warp. The ship receives no endurance extension for travelling below its Maximum rating. Operation above Standard warp but at or below Sustainable warp neither consumes nor restores endurance. Operation at or below Standard warp restores an equivalent amount of time of Maximum warp endurance, up to the ship’s rated allowance.

====Recovery from Maximum warp====
: '''''Note:''' this is a house rule.''

To regain its full Maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at Maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.

If operation at Maximum warp resumes before recovery is complete, the ship’s available safe Maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.

: ''Example: The USS Memphis, rated for eight hours at Maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe Maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Operating between Sustainable and Maximum speeds====
: '''''Note:''' this is a house rule.''

For endurance, recovery, and overrun damage purposes, operation at any speed above Sustainable warp counts as operation at Maximum warp. The ship receives no endurance extension for travelling below its Maximum rating. Operation above Standard warp but at or below Sustainable warp neither consumes nor restores endurance. Operation at or below Standard warp restores an equivalent amount of time of Maximum warp endurance, up to the ship’s rated allowance.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule.''

To regain its full maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.

If operation at maximum warp resumes before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.

: ''Example: The USS Memphis, rated for eight hours at maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Speeds between Sustainable and Maximum speeds====
: '''''Note:''' this is a house rule.''

For endurance, recovery, and overrun damage purposes, operation at any speed above Sustainable warp counts as operation at Maximum warp. The ship receives no endurance extension for travelling below its Maximum rating. Operation above Standard warp but at or below Sustainable warp neither consumes nor restores endurance. Operation at or below Standard warp restores an equivalent amount of time of Maximum warp endurance, up to the ship’s rated allowance.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule.''

To regain its full maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.

If operation at maximum warp resumes before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.

: ''Example: The USS Memphis, rated for eight hours at maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

'''Note:''' It is important to understand that the values listed ''on this table'' are in the [[Warp_Scales#Glossary|TNG scale]], which was adopted in [[2312]]. However, when these multiphasic nacelles were first introduced ([[2305]]), the OCU scale was still in effect and the nacelles were noted to achieve lightspeed multiples aligned with the OCU warp factors.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Speeds Between sustainable and maximum speeds====
: '''''Note:''' this is a house rule.''

For endurance, recovery, and overrun damage purposes, operation at any speed above sustainable warp counts as operation at maximum warp. The ship receives no endurance extension for travelling below its maximum rating. Operation above standard warp but at or below sustainable warp neither consumes nor restores endurance. Operation at or below standard warp restores an equivalent amount of time of maximum warp endurance, up to the ship’s rated allowance.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule.''

To regain its full maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.

If operation at maximum warp resumes before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.

: ''Example: The USS Memphis, rated for eight hours at maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Speeds Between sustainable and maximum speeds====
: '''''Note:''' this is a house rule.''

For endurance, recovery, and overrun damage purposes, operation at any speed above sustainable warp counts as operation at maximum warp. The ship receives no endurance extension for travelling below its maximum rating. Operation above standard warp but at or below sustainable warp neither consumes nor restores endurance. Operation at or below standard warp restores an equivalent amount of time of maximum warp endurance, up to the ship’s rated allowance.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule, as indicated by the italics.''
''To regain its full maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.''

''If operation at maximum warp resumes before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.''

: ''Example: The USS Memphis, rated for eight hours at maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Speeds Between sustainable and maximum speeds====
: '''''Note:''' this is a house rule, as indicated by the italics.''

For endurance, recovery, and overrun damage purposes, operation at any speed above sustainable warp counts as operation at Maximum warp. The ship receives no endurance extension for travelling below its Maximum rating. Operation at or below Sustainable warp neither consumes nor restores endurance while warp propulsion remains engaged.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule, as indicated by the italics.''
''To regain its full maximum warp endurance, a ship must operate at or below Standard warp for a period equal to the time spent safely operating at maximum warp. Recovery time may be divided into separate periods, combining time with warp propulsion at or below Standard warp. Travel above Standard warp does not count as recovery.''

''If operation at maximum warp resumes before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each unit of time with warp propulsion operating at or below Standard warp restores an equivalent unit of time of endurance, up to the ship’s rated allowance. Restarting the system or changing speed does not reset this allowance.''

: ''Example: The USS Memphis, rated for eight hours at maximum warp, operates at that speed for five hours, then travels at Standard warp for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed 
: '''Note:''' The ship's maximum warp factor should be used for budgeting the ship's mandatory power requirements. 
'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Speeds Between sustainable and maximum speeds====
: '''''Note:''' this is a house rule, as indicated by the italics.''

For endurance, recovery, and overrun damage purposes, operation at any speed above sustainable warp counts as operation at Maximum warp. The ship receives no endurance extension for travelling below its Maximum rating. Operation at or below Sustainable warp neither consumes nor restores endurance while warp propulsion remains engaged.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule, as indicated by the italics.''
''To regain its full maximum warp endurance, a ship must disengage its warp propulsion system for a period equal to the time spent safely operating at maximum warp. This recovery time may be divided into separate periods; travel at any warp speed does not count as recovery. Disengaging warp propulsion does ''not'' require shutting down the warp core.''

''If warp propulsion is reengaged before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each hour with warp propulsion disengaged restores one hour of endurance, up to the ship’s rated allowance. Restarting the system does not reset this allowance.''

: ''Example: The ''USS Memphis'', rated for eight hours at maximum warp, operates at that speed for five hours, then disengages warp propulsion for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

However, when these multiphasic nacelles were first introduced ([[2305]]), the OCU scale was still in effect and the nacelles were noted to achieve lightspeed multiples aligned with the OCU warp factors.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====Recovery from maximum warp====
: '''''Note:''' this is a house rule, as indicated by the italics.''
''To regain its full maximum warp endurance, a ship must disengage its warp propulsion system for a period equal to the time spent safely operating at maximum warp. This recovery time may be divided into separate periods; travel at any warp speed does not count as recovery. Disengaging warp propulsion does ''not'' require shutting down the warp core.''

''If warp propulsion is reengaged before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each hour with warp propulsion disengaged restores one hour of endurance, up to the ship’s rated allowance. Restarting the system does not reset this allowance.''

: ''Example: The ''USS Memphis'', rated for eight hours at maximum warp, operates at that speed for five hours, then disengages warp propulsion for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

__toc__
==6.1 Warp Propulsion System==
'''Cost:''' varies

The following information—up until the nacelles entry—is provided as information on the roles of the various parts of the warp propulsion system.

The heart of any starship is its matter/antimatter reaction (M/AMR) engine, more commonly known as its warp propulsion system or warp drive. Put simply, a warp propulsion system works by annihilating antimatter with matter in a lithium- or dilithium-controlled reaction which is channeled for power. A warp propulsion system has three main parts: the matter/antimatter integrator (or matter/antimatter reaction assembly in the [[24th century]]), the power transfer conduits and the warp nacelles. In developing the warp propulsion system, the nacelles and power transfer conduits are "bought" first, with the warp drive considered during the Power portion.

Matter/Antimatter Integrator (M/AMI) (Pre-[[2303]]): Basically, early model warp propulsion systems work the same as [[24th century]] ones. Both annihilate matter and antimatter in a reaction controlled by lithium or dilithium crystals to produce sufficient power to propel a starship at speeds far in excess of the speed of light. However, the technology of the earlier warp drives suffers from certain limitations and restrictions which later drives do not—most notably an inability to safely attain warp speeds higher than warp 8.0 (Warp 6.5 on the [[Warp_Scales#Glossary|TNG scale]]).

On early starships, the matter/antimatter reaction occurs in a matter/antimatter integrator (M/AMI; also called an intermix chamber or warp core). Located in main engineering, the M/AMI consists of a long horizontal chamber in most ships of the era. Beginning in [[2271]], Star Fleet discovered it could achieve a more efficient reaction with a chamber containing both horizontal and vertical sections. (Later advances in materials science and warp engine dynamics in the [[2300s]] —specifically [[2303]]—allowed Star Fleet to discard the less-efficient horizontal chamber in favor of wholly vertical warp cores, except in those designs, such as the ''[[Guide: Danube|Danube]]''-class runabout, where the size or configuration of a ship required a horizontal core.)

The dilithium crystal converter assembly (DCCA), part of the M/AMI, holds the dilithium crystals in place. Most DCCAs hold four crystals, and use a dilithium sequencer to control the flow of power through them. (If anyone removes any crystals, reduce the ship’s ability to attain warp speeds proportionately.) If something fuses or damages a ship’s DCCA, the ship cannot attain warp speed or derive any power from the warp propulsion system until the engineers repair it. Special structures known as baffle plates cover the DCCA to contain the massive energy generated there and channel it into the plasma transfer conduits (PTCs) that carry it to the warp nacelles. If the baffle plates become warped or damaged, they cannot properly contain the reaction, resulting in extensive damage to the engineering section (and possibly the destruction of the ship).

The wider the engineers open the integrator, the greater the flow of matter and antimatter into the chamber, and thus the faster the ship moves. In the event the flows become too great, which could destroy the ship via an uncontrolled reaction or excessive speed (see below), the emergency overload bypass engages almost instantaneously. The bypass possesses great durability; fusing it shut so that it can’t engage would require all the power in the main phaser banks. But if it is fused, or malfunctions, the engines run wild, with a “maximum overload” (resulting in destruction of the ship) in no more than 15 minutes. (The 15-minute figure applies to ships of the [[2260s]] and beyond. For every full 20 years prior to [[2260]], reduce the time by one minute.)

If the integrator does not mix the matter and antimatter in the proper ratio, an “engine imbalance” results. An imbalance of too much antimatter typically destroys the ship, since the excess antimatter contacts matter and explodes. An imbalance of matter can create a “wormhole,” a sort of “tunnel” in space that traps the ship (and possibly other objects, with which the ship may collide). Dropping to impulse speeds causes the wormhole to disappear. If a ship fails to get out of a wormhole before reaching its end, the wormhole’s terminus could put the ship at virtually any place in the galaxy, at any point in time. The plasma produced by a [[23rd century]] M/AMI must maintain a constant temperature between 4,000o and 4,400o Celsius, or else safety margins are violated. If the temperature exceeds 5,500o C, a reaction could result which overheats the engines and destroys the ship in a tremendous explosion.

Ships built prior to [[2303]] cannot eject their warp cores.

Matter/Antimatter Reaction Assembly (M/ARA) (Post-[[2302]]): The matter/antimatter reaction assembly is where the matter/antimatter annihilation takes place. It has three parts: the reactant injectors; the magnetic constriction segments; and the matter/antimatter reaction chamber. These pieces are organized in a columnar fashion. At the bottom and top of the column are the reactant injectors — the matter reactant injector (MRI) sits on the top and uses deuterium; the antimatter reactant injector (ARI) sits at the bottom and uses antimatter. The two work in approximately the same way, but the ARI is adapted for magnetic suspension fuel tunnels, since the antimatter cannot be allowed to touch matter, lest a catastrophic explosion occur. The MRI and ARI inject their treated materials into the magnetic constriction segments (MCSs), which align the materials for combining within the matter/antimatter reaction chamber (M/ARC). The M/ARC consists of two bell-shaped cavities joined together to direct the flow of the materials. Where the two halves are joined, there is a dilithium crystal articulation frame (DCAF) which holds a dilithium crystal. An armored hatch allows access to the DCAF when it’s time to replace or adjust the crystal.

For reasons not fully understood, dilithium is the only substance known not to react with antimatter when subjected to a high-frequency electromagnetic field. The matter and antimatter both pass through the crystal’s structure without touching it, come into contact with each other, and are annihilated in a reaction which produces an enormous amount of energy. That energy, in the form of plasma, is directed by the dilithium crystal towards the power transfer conduits (PTCs).

Power Transfer Conduits and Warp Nacelles: The Power Transfer Conduits (PTC) split the plasma into one stream for each nacelle a ship has and use magnetic constriction to force the stream(s) toward the warp nacelle(s). Along their length there are three electroplasma system (EPS) taps which siphon off power to run the ship’s systems. The PTCs terminate at the warp nacelles. The nacelles have three primary parts: plasma injection system; warp field coils; and the emergency separation system. They also have maintenance docking ports.

At the nacelle end of each PTC, the plasma injector systems (PISs) injects the plasma into the warp field coils (WFCs) as a burst of energy. The WFCs, which are split toroids made of tungsten-cobalt-magnesium and verterium cortenide, use the energy to create an intense, multilayered warp field which allows the ship to travel through space at superluminal speeds. The coils shift the energy frequencies carried by the plasma deep into subspace, creating the warp field. The sequential firing of the coils presses the warp field layers upon each other, thus making the vehicle move. Because two warp nacelles create a precisely balanced interacting warp field, most ships have that many nacelles; however, advances in warp field theory and mechanics have made ships with one, three, or four nacelles possible. Odd number nacelle designs require the designers to precisely align the odd nacelle along the X-Y plane of the ship, and in the case of three nacelles to precisely align the third one between the other two nacelles, to prevent warp field misalignment.

The nacelles also include Bussard ramscoops at their forward end. A ship can use these to “sweep” interstellar space with a magnetic field to gather stray hydrogen atoms in the event of a fuel shortage. If necessary, other gases (such as metreon gas) can be collected. By making a Routine (3) Propulsion Engineering Test, the crew can “backflush” the ramscoops, ejecting the collected gases forward or aft.

The emergency separation system (ESS) allows the crew to eject a nacelle in the event of catastrophic failure of a PIS. The computer controls this function; no Test is required for characters to activate it. In the event of a computer failure, characters can make a Moderate (6) Systems Engineering or Shipboard Systems (any Specialization) Test to perform the ejection — assuming, of course, the ejection system hasn’t malfunctioned...

Lithium and Dilithium: Warp propulsion systems use a controlled matter/antimatter reaction explosion to generate the massive amounts of energy needed to transcend the speed of light. Early warp engines, such as the one invented by Zefram Cochrane, typically used laboratory-created lithium crystals to control the reaction, but they proved unstable. Experiments conducted in the late [[2240s]] and early [[2250s]] with a new substance, dilithium, determined that it functions more efficiently and safely than lithium, and by approximately [[2264]] it had replaced lithium in almost all warp propulsion systems. The Federation and comparative societies cannot manufacture dilithium; they have to mine it. That makes sources of the mineral, such as the planets [[Coridan]] and [[Troyius]], or the Klingon asteroid of [[Rura Penthe]], enormously valuable (and often the sources of galactic political tension).

Dilithium is sturdy, but not invulnerable. A wide variety of phenomena, ranging from physical force to various energy and subspace fields, can cause dilithium crystals to warp, crack, or deteriorate past the point of usefulness (they also wear out through use, of course). If this occurs, the engineering department must replace them immediately or risk the destruction of the ship due to an uncontrolled matter/antimatter reaction. The engineers cannot replace the crystals without shutting down the warp propulsion system entirely. In [[2286]], Captain Spock of the [[USS Enterprise (NCC-1701)|''USS Enterprise'' ]] devised a method of recrystallizing dilithium using high energy photons from fission reactors which greatly extended the usable life of an individual crystal.

Because dilithium is both rare and expensive, ships often have difficulty keeping enough of it in supply, prior to 2286. A starship typically carries enough dilithium for one year of routine operation. Whenever it has to exceed Standard speed, activates shields or other power-intensive systems, it uses up more than it would by engaging in routine operations for the same period of time. Eventually the ship must obtain more dilithium. The same useage rules apply to lithium, though it is much more common.
----
'''Cardassian:''' The [[Cardassian Union]] uses a unique form of warp drive technology. Because Cardassian industrial processes cannot produce antimatter as pure and refined as that manufactured by the [[Federation]] or [[Romulans]], Cardassian warp drives use a magnetic latticework focused by a mineral called ladarium to help purify the antimatter before it interacts with the matter. Without ladarium, a Cardassian ship risks catastrophic warp core breach, since it cannot fully regulate the matter/antimatter reaction and resultant power flow. Cardassian ships carry ladarium as part of their consumables, but as with dilithium and crucial spare parts, always seem to run out at inopportune moments, which gives rise to difficulties and adventures.

The maximum speed attainable by Cardassian vessels as of [[2376]] is Warp 9.7. Using technological information obtained from the [[Dominion]], the Cardassians may learn how to exceed this speed, once they solve their current political troubles and can concentrate on such research again.
----
'''Klingon:''' The [[Klingons]] use standard matter/antimatter warp propulsion technology and impulse propulsion systems. They have conducted a few experiments with transwarp drive and other advanced forms of superluminal travel, but have never even come close to developing practical working models of such technology.

The maximum speed attainable by Klingon vessels as of [[2376]] is Warp 9.8.

===6.1.1 Nacelles===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' 1 Power for every 0.2 of warp speed

'''Available:''' [[2063]]

There are two different designation systems for nacelles used by Star Fleet and its preceding agencies: the first was used up until [[2312]], when nacelles were redesignated according to how they performed under the TNG Warp Scale (this was done retroactively, in some cases). The first system labels the nacelles by Mark, while the latter system uses Type. Nacelles from one system are different than those used under the other, as the latter type began incorporating the third-generation knowledge of warp mechanics.

Decide how many nacelles your ship has, from one to four. The base number you choose doesn’t matter or affect the <strike>SU</strike> mass cost—four nacelles cost as many as one or two, and the number chosen has no particular effect on gameplay. The Nacelle Table indicates the types available, their <strike>SU</strike> mass cost, and the Standard / Sustained / Maximum warp speed each can attain. Standard velocity (''aka'', '''cruise speed''' in ''Timo's Guide'') is the speed at which a ship commonly cruises through space. Sustainable velocity is the highest speed it can maintain without stressing the ship or its engines. Maximum velocity (''aka'', '''max speed''') is the highest speed it can attain (see also Plasma Injection System, below).

Warp travel costs 1 Power for every .2 of warp speed (or fraction thereof), or 5 Power for every full warp factor. For example, a ship moving at Warp 5 must spend 25 Power per round to do so; one moving at Warp 7.5 spends 38 Power. (Since combat rarely takes place at warp speed, this cost usually does not come into consideration during play.)

Ships designed prior to [[2269]] almost always have two nacelles—no more, no less—because warp field theory had not yet advanced to the point where Star Fleet technology could reliably generate a stable warp field with one, three, or four nacelles. One-nacelle arrangements became available in [[2269]], with three- and four-nacelle arrangements in [[2284]].

Retractable nacelles (+3 SU) became available in [[2337]].

Variable-geometry nacelles (+5 SU) became available in [[2371]], as part of the efforts to overcome the Warp 5 speed damage effect on local subspace. This reduces the Power cost for Sustainable and Maximum warp speed by 2. Variable-geometry nacelles cost +5 SUs; it takes 5 Power and one round to alter the nacelles’ position.

Embedded nacelles can only be installed on Cardassian and Klingon vessels (to date) of Size 5 or larger, but they do help make shields stronger, because the shield radius becomes smaller (increase Threshold by 10 and Protection by 100 for no additional Power cost). The cost, however, is that the warp field is slightly less efficient (reduce Standard, Sustainable, and Maximum speeds by 0.1 each) and the embedding also costs 4 x Size. Star Fleet has not yet adopted fully embedded nacelles because it dislikes the loss of speed entailed and is concerned about the health and safety implications they might have for a ship’s crew, but has employed some of the principles to design ships such as the ''Saber'' and ''Steamrunner'' classes with partly embedded nacelles.

Note: Speeds listed with the Mark series are according to TOS (“The Original Scale”), also known as the Cochrane Scale. The Type series, first introduced in [[2313]], is listed in the TNG (“Terrance-Neltorr Graduated”) Scale, which was adopted in [[2312]]. TOS factors are marked with a lower-case "w"; TNG factors are indicated by a capital "W".

====Special Note Regarding Nacelle Mass (versus SU)====
SFC moves away from using SU to define the “cost” of nacelle sets. Timo makes [[Guide:A_Word_Or_Two_From_The_Author|a compelling argument]] that nacelles constitute a substantial proportion of a vessel’s total mass—something ''Spacedock'' does not model especially well.

Instead, SFC determines the mass assigned to each nacelle set (regardless of how many individual nacelles the set contains). The vessel’s standard warp speed—the speed at which it is expected to cruise most often—accounts for the largest share of that mass cost. The technologies required to achieve sustained and maximum warp speeds add comparatively less. Enhancements that raise any of these speed ratings, applied to successive nacelle sets, increase their required mass accordingly.

The vessel’s target mass determines the metric-ton mass represented by each SU. Multiplying the target mass by the applicable nacelle-mass percentage produces the mass allocation, in metric tons, for that nacelle set. The equivalent SU value should be displayed alongside the tonnage.

Nacelle attributes—such as retractability or variable geometry—continue to use their original ''Spacedock'' SU costs.

====Tables====
'''Note:''' Designations, mass cost, warp speeds, and the year of availability have all been changed from those originally provided by ''Spacedock'' and ''Ship Recognition Manual v4: The Original Series''; additional nacelles have been added as well.

===6.1.2 Warp Drive Systems Upratings/Downgrades===
'''Cost:''' Varies 
'''Power Requirement:''' Adjusted with the [[Build:Warp_Propulsion_System#6.1.1_Nacelles|nacelles]]' power requirements

The bonus provided by the upratings packages adds to any one category of warp speed (Standard, Sustainable, Maximum), but Maximum cannot be increased beyond Warp 9.982 as of [[2376]]. A ship may install as many uprating packages as it has space for and its designers desire. It is represented by increased warp drive equipment (''i.e.'', more required SU space) to account for the increased capability. A downgrade reduces any one category of warp speed. A ship may downgrade its systems as much as its designers desire, though Star Fleet is not likely to allow more than a 0.3 reduction to any category of warp speed for efficiency reasons. This is achieved by miniaturization of the equipment (itself a viable reason for the downgrade).

If a ship gets overhauled with newer technology warp engines, the packages must also be re-installed and re-calculated (if installation is even desired).

===6.1.3 Plasma Injector System===
('''Required''' for most FTL vessels) 
'''Cost:''' Varies 
'''Power Requirement:''' none

The quality and efficiency of a ship’s Plasma Injector System (PIS) indicates how long it can maintain its Maximum warp speed. For every minute of travel beyond the listed time, a ship with the Class series of PIS takes 10-60 (1d6 x 10) SUs of damage as the ship begins to shake itself apart (no defense applies; determine the location of the damage randomly). Additionally, there is a 40% chance the warp propulsion system suffers additional damage; the PIS loses 25% of its SUs, which reduces the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage the PIS sustained.

Starting in [[2271]], new warp theories began to rapidly manifest as new warp realizations and PIS technology began to bound ahead in capability. This increase in plasma injection efficiency led to the adoption of a new nomenclature series. Since the release of the Type J PIS in [[2279]], no significant increases have been made.

For ships with the Type series of PIS installed, a roll of 2d6 should be made for every 10 minutes of travel beyond the listed time; on a result of 2, 3 or 4, the warp drive system suffers damage. Reduce the ship’s Standard, Sustained, and Maximum ratings by 25%. Repairs take one hour to one day per SU of damage as if the PIS had lost 25% of its SUs.

====''Recovery from maximum warp''====
: '''''Note:''' this is a house rule.''
''To regain its full maximum warp endurance, a ship must disengage its warp propulsion system for a period equal to the time spent safely operating at maximum warp. This recovery time may be divided into separate periods; travel at any warp speed does not count as recovery. Disengaging warp propulsion does ''not'' require shutting down the warp core.''

''If warp propulsion is reengaged before recovery is complete, the ship’s available safe maximum warp duration equals its rated endurance minus its unrecovered operating time. In other words, each hour with warp propulsion disengaged restores one hour of endurance, up to the ship’s rated allowance. Restarting the system does not reset this allowance.''

: ''Example: The ''USS Memphis'', rated for eight hours at maximum warp, operates at that speed for five hours, then disengages warp propulsion for three hours. Two hours of operating time remain unrecovered, leaving six hours of safe maximum warp available.''

===6.1.4 Coaxial Warp Drive ===
'''Cost:''' Varies (see table) 
'''Power Requirement:''' Varies (see table) 
'''Available:''' [[2374]]

Coaxial warp drive systems operate on different principles than standard warp drives. Instead of creating a warp field and manipulating that to create propulsion, a coaxial warp drive creates a warp field and then “folds” space (perhaps in a manner similar to the folded-space transport posited by the Elway Theorem). This allows a ship to travel immense distances instantly. Furthermore, due to the technique used, a ship runs no danger of accidentally colliding with space objects, since it’s not actually traversing normal space.

A coaxial warp drive can fold space each round. This translates into velocities far in excess of Warp Factor 9.9. (See below table for exact speeds.) To build a coaxial warp drive, buy a warp engine (i.e., M/ARA) as normal for your ship. Then buy a coaxial warp drive system from the accompanying table, which also indicates SU cost. That cost includes the cost of nacelles and other components found in a normal warp propulsion system.

Because coaxial warp drive is still an experimental and unproven technology which is prone to overload due to particle instabilities, characters must make a Challenging (10) Propulsion Engineering (Coaxial Warp Drive) Test every round to use it successfully. Failure indicates the drive breaks down; the ship cannot use it again until engineers make repairs (this takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Coaxial Warp Drive) Test). Dramatic Failure indicates that the drive catastrophically breaks down. This destroys the ship, kills everyone aboard, and collapses space in an area with a billion-kilometer radius around the ship.

To stabilize the coaxial warp drive, a ship can establish a symmetric warp field. This requires a Moderate (8) Propulsion Engineering (Warp Drive) Test. If the Test succeeds, the field is established; it costs 10 Power per round and reduces the Difficulty for the Test to operate the coaxial warp drive correctly to Moderate (8). If the Test fails, the ship cannot establish the field at all (further Tests are not allowed) for one day. If it’s Dramatically Failed, the effects are as per failure, plus subspace stresses result which cause 4d6 damage to the ship (only the structural integrity field protects against this).

(''To be re-written with the chosen roll rules.'')

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

('''Romulan''': The Romulans have conducted experiments with coaxial warp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.5 Quantum Slipstream Drive ===
'''Cost:''' 80 
'''Power Requirement:''' 120 Power per round 
'''Available:''' [[2374]]

Quantum slipstream drive (QSD), like a coaxial warp drive, allows a ship to move at velocities far exceeding standard warp drive—approaching the upper Warp 9.999 range. The system routes energy from the quantum drive to the main deflector, which creates a “slipstream” in subspace through which the ship travels. Due to the slipstream’s size, a ship without a QSD can enter it and travel along behind the vessel generating the “tunnel.” The instabilities created by a quantum slipstream pose significant dangers to a ship, in that it places enormous pressure on the ship’s SIF and hull, and can rupture the latter. Furthermore, maintaining the slipstream is difficult, and if it collapses, it can damage or destroy the ship(s) inside it.

Using a quantum slipstream drive requires a Challenging (9) Shipboard Systems (Flight Control) Test every round. If the Test fails, the instabilities cause 120+8d6 damage to the ship (only Resistance and the SIF protect against this damage) and the ship drops out of the slipstream. If the Test results in a Dramatic Failure, increase the damage to 200 x 1d6. If the Test succeeds, a QSD allows a ship to travel at the rate of 300 light-years per hour (just under half a light-year per round).

A QSD requires 80 SUs and includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to act as a backup for the QSD; if so, it must buy all necessary parts for such a system.

Not readily available to Star Fleet, the technology was first encountered in [[2374]].

===6.1.6 Soliton Wave Propulsion ===
'''Cost:''' none 
'''Power Requirement:''' none 
'''Available:''' [[2368]]

This form of propulsion, first tested in [[2368]] by Dr. [[Ja’Dar]] of [[Bilana III]], uses a soliton wave (a nondispersing wavefront of subspace distortion) to “push” a starship through space in much the same way a wave of water pushes a surfboard. To function, it requires soliton wave stations at either end of the space traveled (for example, the two planets forming the hubs of a trade route). When it works properly, ships are propelled quickly between the two points. However, the wavefront has so far proven difficult to control, and when out of control can damage the ship using the system.

Using a soliton wave propulsion system requires a Moderate (5) Shipboard Systems (Flight Control) Test from the pilot of the ship, and one or more Moderate (7) Propulsion Engineering (Soliton Wave Propulsion) Tests from the person operating the equipment. If either Test is failed, the ship takes 12d6 damage (only the SIF protects against this damage) and drops out of the wave. For Dramatic Failure, increase the damage to 20d6. If both Tests succeed, the ship travels at Warp 9.0 at no Power cost. Soliton wave propulsion requires no SUs on a ship using it.

('''Romulan''': The Romulans have conducted experiments with soliton propulsion, but—like the Federation—they have yet to develop a practical working model.)

===6.1.7 Transwarp Drive===
'''Cost:''' 15 x Size 
'''Power Requirement:''' (15 x Size) Power per round 
'''Available:''' [[2369]]

Used by, among others, the [[Borg]], transwarp drives allow a ship to create a “corridor” in space-time from one place to another. A ship using the corridor travels at Warp 10, a velocity unattainable with standard warp drives. A transwarp drive does this by emitting tachyons which breach the subspace barrier and allow the ship to create a transwarp corridor (similar in many ways to a wormhole) by “folding” subspace.

The [[Federation]] began experimenting with transwarp drives in the [[2280s]], with the ''[[USS Excelsior]]'' serving as a testbed for the prototype. Unfortunately, the trials were a failure, in that Star Fleet could not determine how to exit the transwarp corridor at a predefined point (the desired destination). Theories also posit that transwarp travel could cause disfiguring mutations in humanoids. However, encounters with the Borg beginning in [[2369]] showed that they had solved these problems and developed a transwarp drive at least 20 times faster than conventional warp drives.

Assuming the difficulties were overcome, a transwarp drive would work as follows. It occupies 15 x Size in SUs. This SU cost includes all parts needed to operate the system; the ship does not have to buy nacelles or the like. However, it may wish to buy a warp propulsion system to generate Power or to act as a backup for the transwarp drive; if so, it must buy all necessary parts for such a system. If it has normal nacelles, it must establish a depolarization matrix around the ship’s fuselage to prevent the transwarp velocity differential from tearing the fuselage away from the nacelles.

When activated, a transwarp drive creates a transwarp corridor which allows a ship to cross distances as if traveling at 20 times its normal Maximum warp speed.

Operating a transwarp drive requires a Challenging (10) Propulsion Engineering (Transwarp Drive) Test. Success means the ship travels the desired distance. Failure means the drive breaks; it takes 1d6 hours and a successful Moderate (8) Propulsion Engineering (Transwarp Drive) Test to repair it. Dramatic Failure indicates that the drive malfunctions, taking the ship an enormous distance off-course (the Narrator determines exactly how much; 1d6 x 100 light-years is a good rule of thumb). It then breaks, requiring 1d6 days and a successful Challenging (9) Propulsion Engineering (Transwarp Drive) Test to repair.

After a transwarp drive is used, the transwarp corridor remains open for 1d6 rounds. Other ships can enter it with a Routine (4) Shipboard Systems (Flight Control) Test during that time and make use of its properties even though they lack transwarp drive—but when the corridor shuts, they’re stuck on the other end.

('''Romulan''': The Romulans have conducted experiments with transwarp drive, but—like the Federation—they have yet to develop a practical working model.)

===6.1.8 One-Way Warp Propulsion===
'''Cost:''' 60 
'''Power Requirement:''' none

Some species, most notably the Romulans, develop a more limited form of warp propulsion technology before proceeding to true warp drives. Known colloquially as one-way warp propulsion, this drive allows the ship to travel at warp speeds—once. When the ship shuts off its warp drive, or it runs out of fuel, it must limp back home on impulse (a journey of months or years).

A one-way warp drive typically consists of a single-use magnetic bottle towed behind a ship. The bottle contains superdense plasma. To achieve superluminal speed, the ship detonates the plasma, creating a short-lived, controlled black hole that propels the ship to a designated destination within 300 light-years. Once used, the system cannot function again until it can have the bottle reinstalled and the superdense plasma resupplied at a properly-equipped space station.

Activating a one-way warp propulsion system requires a Moderate (6) Propulsion Engineering (Warp Drive) Test to ensure the bottle is properly calibrated to send the ship to the desired destination (anywhere within 300 light-years). If the Test fails, the ship ends up at the wrong destination (typically 1d6 light-years off-course per point the Test failed by); Dramatic Failure destroys the ship in a massive explosion. The trip takes one minute per light-year traveled.

A ship with a one-way warp propulsion system must buy an IDF (with Strength 6) at half the normal cost. Ships with one-way warp propulsion systems typically have very primitive ion power generation systems that occupy 50 SUs and generate 150 Power per round. They may also have impulse engines and solar power generation.

===6.1.9 Ion Propulsion (Advanced)===
'''Cost:''' 60 
'''Power Requirement:''' Varies (see table)

Some advanced civilizations, such as the [[Eymorg]] under the influence of the Teacher, use a form of propulsion and power generation known as ion propulsion. More sophisticated than Federation, Romulan, or Klingon technology, ion propulsion of this nature provides greater speed and more power than comparative Star Fleet engines (see accompanying table). Ships with ion propulsion systems do not need standard power generation or warp propulsion systems, but must buy a standard PIS system. The below table provides warp speeds in the Cochrane Scale.

===6.1.10 Taurhai Gravity Induction Drive===
'''Cost:''' Varies 
'''Power Requirement:''' Varies (see table)

As described on page 96 of ''Book One'' of the ''Way of D’era'' boxed set, the [[Taurhai]] use a gravity induction drive (also referred to as a “subspace funnel”) to create what amount to “micro-wormholes” (though they don’t necessarily function identically to naturally-occurring wormholes found in space). Their ships then “fall” or “slide” through these funnels in subspace, crossing light-years in mere seconds. Though the use of a gravity induction drive creates a graviton wavefront and wake which other ships can detect, once the ship enters subspace via its “funnel” other ships cannot detect it, allowing it to “appear” seemingly instantaneously in position to make devastating surprise attacks.

Activating and using a gravity induction drive requires two full rounds of effort by most of the ship’s engineering crew per jump (one round to prepare the drive, one round to activate it). During normal travel, simply use the “LY Per Minute” column in the accompanying table to determine how fast the ship travels with its ongoing series of jumps. In combat situations or other crises, the “Maximum Jump Length” column may come into play, giving the Romulans a slim chance to catch a Taurhai ship before it escapes them completely.

Taurhai ships have matter/antimatter cores to generate power on their ships — large ones, given the power requirement of their gravity induction drives. They buy them using the normal ''Spacedock'' rules. They do not buy nacelles or other warp propulsion system elements to drive their ships directly with M/AM power.

The accompanying table provides details on gravity induction drives, including the maximum length of the “jump” the ship can make, and the maximum number of light-years the ship can cross
per minute using the drive.

Typically a ship can only use its Gravity Induction Drive for about two to three hours per day total, either continuously or spread over the course of the day; this means a maximum of 1,080 jumps per day. More than that poses a severe risk of breakdown. For each jump beyond 1,080, the Narrator rolls 1d6; on a roll of 1, the engine breaks down and requires 2d6 x 4 hours to repair.

Help:Ship Class page

Dan:

A '''Ship Class''' page is an article that depicts a class of ship (and often it's flights & sub-classes, but not variants, as defined below) as it is used within the game. It will often ''not'' match the same class's historical article in ''Timo's Guide'', nor may it necessarily follow the historical events that were originally intended for that class in the game.

: 1. Cut & paste the following code into the blank ship class article; if a field is unknown, leave it blank.
::* Classification: the class category (from the vessel's Guide article)
::* Affiliation: governing authority
::* Ordered: quantity originally ordered
::* Completed: quantity eventually constructed
::* Operational: years of operation
: 2. For the '''image''' field, just the name of the image is sufficient. e.g., ''Example.jpg'', ''Example.png'', etc.
: 3. For the '''costs''' field, review the [[Purchase_and_Maintenance_Costs#Purchase|Purchase rules]].
: 4. Save new article.
: 5. Add the text of the article between the sidebar template and the index.

Dan:

A '''Ship Class''' page is an article that depicts a class of ship (and often it's flights & sub-classes, but not variants, as defined below) as it is used within the game. It will often ''not'' match the same class's historical article in ''Timo's Guide'', nor may it necessarily follow the historical events that were originally intended for that class in the game.

: 1. Cut & paste the following code into the blank ship class article; if a field is unknown, leave it blank.
::* Classification: the class category (from the vessel's Guide article)
::* Affiliation: governing authority
::* Ordered: quantity originally ordered
::* Completed: quantity eventually constructed
::* Operational: years of operation
: 2. For the '''image''' field, just the name of the image is sufficient. e.g., ''Example.jpg'', ''Example.png'', etc.
: 3. For the '''costs''' field, review the [[Purchase_and_Maintenance_Costs#Purchase|Purchase rules]].
: 4. Save new article.
: 5. Add the text of the article between the sidebar template and the index.

Help:Ship Class page

2026-10-10T20:06:40Z

Dan:

A '''Ship Class''' page is an article that depicts a class of ship (and often it's flights & sub-classes, but not variants, as defined below) as it is used within the game. It will often ''not'' match the same class's historical article in ''Timo's Guide'', nor may it necessarily follow the historical events that were originally intended for that class in the game.

: 1. Cut & paste the following code into the blank ship class article; if a field is unknown, leave it blank.
::* Classification: the class category (from the vessel's Guide article)
::* Affiliation: governing authority
::* Ordered: quantity originally ordered
::* Completed: quantity eventually constructed
::* Operational: years of operation
: 2. For the '''image''' field, just the name of the image is sufficient. e.g., ''Example.jpg'', ''Example.png'', etc.
: 3. For the '''costs''' field, review the [[Purchase_and_Maintenance_Costs#Purchase|Purchase rules]].
: 4. Save new article.
: 5. Add the text of the article between the sidebar template and the index.

==''Valiant'' Flight Configuration==
* identical to ''Defiant'', with the exception of cargo holds with 26 additional SU, leaving no full SU remaining

==Production==

==Notes==
* The ''Defiant'' was originally built as the ''Akademik Fedorovich Ioffe'' (AOS-11033) and the ''Valiant'' as the ''Akademik Sergey Vavilov'' (AOS-11031), both of the [[ECON]]'s [[Akademik Mstislav Keldysh class|''Akademik Mstislav Keldysh'' class]] cruisers.
