In the [[2140s]], the enemy stalking [[Earth]]’s transports and lone patrol vessels remained as faceless as
ever, yet was beyond any doubt a formidable one. A military confrontation was a distinct possibility,
yet few measures were taken to prepare for a full-scale war this early on – for a good practical
reason. From the viewpoint of the [[24th century]], it is easy to forget that a [[22nd century]] ship built for
offensive military action would be unsuited for hunting pirates or protecting colonies, let alone
performing missions of exploration or diplomacy. Harsh choices thus had to be made concerning
Earth’s limited resources; certain mission categories had to be ignored to allow others to receive
equipment. Instead of a generic warfleet, the [[UESF]] desired at least a dozen high profile cruisers to bluff
its way to interstellar respect. What little remained had to be allocated to defensive rather than offensive forces – and the defenders would have to be able to cover both the star system and deep
space battlefields.


The first type of combat theater was familiar enough to the UESF. The aerodynamically shaped
''[[Guide:Emmette|Emmette]]'' destroyers provided a sturdy template for a system defender. Adding of recent innovations
in armaments and defenses would result in a capable in-system combatant with minimal expenses.
Out-system duties would be a wholly different challenge, though. The ''Emmettes'' could be considered
‘warp-augmented’ at best; the new destroyer would have to mount practical deep space engines of
full warp three performance. This would be a major investment in R&D, construction and systems
integration alike.
There was one final ‘border condition’ defining the new destroyer. Military tradition suggested
organizing the harassed transports into convoys protected by escorting spacecraft – yet as space was
vast and the number of transport runs needed to support interstellar colonies quite staggering,
hundreds of escort vessels would be needed to effectively secure Earth’s commerce. The UESF thus was
forced to specify an austere design that could be fitted with various sensor and weapon
combinations as the situation warranted. This decision was truly serendipitous, considering that any
fixed equipment standard initially considered for the escort mission would have been quite useless
in the actual wars that followed.

Experimental modifications on available ''Emmette'' spaceframes began almost immediately after the
[[2141]] issuing of the relevant Fleet Requirement. Based on these, [[Empress]] and [[Vickers]] yards at Earth
and [[Mars]] began construction of actual flight articles, somewhat larger in overall size and generally
streamlined and simplified to facilitate modern armoring. The after half of the hull was expected to
see the greatest changes, as outdated power and propulsion systems would be supplanted by
completely differently dimensioned modern counterparts. The two competing entries were presented
by the end of the year, with Empress offering a narrow-hulled design with a swappable combat bow,
and Vickers going for a more conventional flying delta.
Certain key features were dictated to appear on both entrants. Two twin reaction engine nozzle
assemblies were to be mounted astern on extended, swiveling structures that allowed their use in
lifting as well as forward propulsion tasks. Between them was the main reactor, ejectable in extreme
emergencies but mainly mounted this far abaft due to center-of-mass considerations. Atop the
reactor assembly would sit an IMRF stabilizer serving the two broadly outriggered, 80,000 ton warp
nacelles. In combination, the propulsion system would provide full access to and from terrestrial
planets, linear accelerations up to 800 gravities, warp two sustained and warp three flank speeds,
and sufficient maneuverability in all three operational realms.
The Vickers design was selected in February [[2142]], its conservatism the obvious winning point.
Internally, the ship was divided into ten decks, most of which were taken up by massive fuel tanks
and power generation subsystems. The bridge dome at the bow, mere six meters across, was
equipped with armor-shuttered windows opening directly into space for situational awareness in the
close-quarters fights expected in convoy service. The level below housed a quartet of navigational
deflectors and a sensor array forward, and main command and control facilities beneath the
navigation bridge. Crew quarters and various support systems were clustered within the lifting body
hull in a manner that paid little heed to ergonomy or safety. Major systems breaching the polarizable
hull armor included aft ventral semi-recessed berthing for one twenty-person atmospheric shuttle,
six ventrally mounted twin lifting engines and four landing gear bays, a centralized computer
system, and a ventral domed array of medium range sensors.
Primary armament in two ventral banks just below the bridge structures was clustered with the
associated targeting sensors, resulting in two rectangular points of weakness. All-new 600 MW
main lasers were developed by Lockheed; these were intended to be carried only on select missions
due to their complexity and power requirements. Normally, the stations were to be fitted with 45
MW laser emitters and/or plasma guns. Secondary ventral weapons stations were crammed in next
to the aftmost lift engine pairs, each capable of holding one plasma cannon or light laser turret. A
single dorsal station was available aft of the bridge. In addition, two sets of three mine tubes astern
could spew up to 150 thermonuclear mines for system defense, or for discouraging pursuit in
convoy escort duty.

The first six ''Ganges'' units were launched in [[2146]] and equipped with four 450 MW lasers and two 2
GW plasma cannon turrets. After barely two months of validation trials, operational testing was
initiated: ''USS Erie'' and ''USS Keflov'' were sent to escort a group of medium freighters carrying
weapons components, including orbital fortress and space tank modules and much-needed excitator
coils for system defense vessel laser emitters, to [[Earth Colony Six]]. The results were nothing short of
tragic. Somehow, Romulans had found out about the delivery, and mounted a raiding party that
penetrated into nominally Earth-patrolled space and engaged the convoy. The lasers of the
destroyers worked as planned, cutting to pieces one alien missile boat per minute – but in less than
three minutes, the ships had been overrun and their relatively light armor peeled open by superior
numbers of attackers. There were no survivors aboard the destroyers, and only one of the freighters
managed to escape into high warp. Until [[2164]], the raid was labeled the work of Nausicaans, until
sensor data from the surviving ''SS Tupac Amaru'' was properly reanalyzed to reveal classic Romulan
duplicity.
Even the initial post-mission analysis called for a stepping up of response, though. Not only had the
rate of fire of the destroyers been found insufficient, but the range of engagement with the
secondary lasers was too close for the safety of the convoy. The heavy 600 MW laser was clearly
needed even against adversaries as puny-looking as pirate missile boats.
Subsequent deployments of ''Ganges'' escorts eventually resulted in all ships carrying the maximum
weapons load, with a 50/50 balance of lasers and plasma turrets on the secondary mounts. Still, the
first truly efficient combat fit had to wait until [[2152]] and the introduction of phased particle beam
weaponry. A pair of Type A phase cannon at the bow was the initial fit, followed by a Type B
cannon on the dorsal mount; mines and most plasma cannon were omitted. The shuttlecraft was
disembarked, as in its exposed position it presented an explosion hazard for little practical return. A
Mk I transporter was soon added in compensation, its emitter array positioned in the shuttle berth.
A total of 49 ''Ganges'' were built during the period when random Romulan raids changed into
systematic interception of transports in preparation for a major attack. Several of the destroyers saw
initial service in anti-Xindi and anti-Klingon operations in the [[Sol]] system, based off Mars where the
ships could operate from surface bases. Moving of operations out to deep space began after the
delivery of the tenth unit, gradually, haltingly: the [[2149]] Nausicaan scare and again the [[2151]] Klingon
incidents made Starfleet hesitate, but shipping protection ultimately received the majority of the
''Ganges'' force.
Homogeneous spreading of the destroyers to interstellar space would have been folly. On the most
endangered shipping lanes, convoying was in [[2156]] changed from constant escort to relay tactics. A
group of destroyers followed a convoy for two to three lightyears, then handed it over to the next destroyer group; random links of the relay chain were watched over by a cruiser, but most were left
completely unprotected. The tactical aim was to keep the Romulans guessing, and to be able to
confront them with decisive force when they guessed wrong. This enormously demanding system
taxed the ''Ganges'' fleet to the extreme, but at least kept the forward colonies and outposts from
becoming totally isolated. A downside was the complete unavailability of escort vessels for any of
the secondary trade routes.
As the Romulans began their main attack, the front lines nevertheless faced a siege of
overwhelming force. The low warp speeds of the ''Ganges'' no longer mattered, as they were pressed
to system defense service and began to fight their battles under impulse power. While the cruiser
and modern destroyer fleets fought in deep space hunting Romulan carriers, ''Ganges'' teams were
used to ambush raiding parties and to wear down assault forces before they entered planetary
bombardment range. Starfleet’s efforts to boost planetary defenses were still hampered by
Romulans constantly intercepting shipments of material intended for this purpose, and there no
longer were destroyers to spare for convoy escort; ''Ganges'' production was terminated in favor of the
more affordable ''[[Guide:Daedalus|Daedalus]]'' corvettes.
[[Image:No Photo Available.jpg|left|200px|thumb|The wreckage of ''USS Tripoli'' being surveyed by the destroyers ''Cooper'' and ''Maryland''. The battle at [[Altair VI]] was the first in the Romulan War where Starfleet managed to send modern destroyers to augment the deep space cruiser force. Compensating for each other’s severe deficiencies, the jointly operating elements managed to reduce casualties, making Altair VI the first engagement in which no stopgap ''Daedalus'' vessels were lost. Planetary defense and assault remained an ''Ganges'' forte throughout the war.]]
Desperate tactics of providing lone freighters or small convoys with single-pilot escort fighters had
no practical effect. Popularly called ‘cochranes’, the dartlike fighters usually consisted of nothing
more than a cockpit and a handful of laser or plasma cannon scabbed onto a bulky warp sustainer
feeding from the warp field of the freighter. Some four hundred were produced between [[2147]] and
[[2159]], but a stupefying 289 lost during the first year of operation. While a 1940s CAM pilot might
have felt close kinship to a ‘cochrane jockey’, the majority of UESF personnel considered this
suicidal method of fighting fit only for saints or fools. It well reflects the desperation of the times
that the line of people waiting for their chance to climb into a cochrane cockpit only grew longer
with each incoming casualty report.
[[Image:No Photo Available.jpg|left|200px|thumb|Two ''[[Guide:Arrow/Galliant/Dagger|Galliant]]'' and two ''Arrow'' class cochranes travel in the wake of ''USS Baikal'' of ''Ganges'' class, in protection of convoy XR-72 to [[Earth Colony Six]]. The destroyer was somewhat ill fitted to serve as a battle control center, lacking in sensors and command and communications facilities. It was therefore typical for one of the transports to be rigged for command duty, with a ranking UESF officer aboard to liaison with the civilian Convoy Commodore, leaving the destroyers and cochranes to concentrate on actual fighting. Such a team could be a deadly opponent to raiders, but usually the cochranes had to make do with partners lesser than ''Ganges''.]]
Despite such bravery, by [[2158]] it began to seem that almost a hundred of the forward colonies and
outposts would have to be abandoned and new defense lines formed closer to Earth. Clearly, a
purely defensive strategy would finally lead to complete destruction.
When Earth’s long-awaited move to the offensive came, it was not merely system- or theaterwide,
but simultaneously affected every single UESF unit involved in the fighting. As is typical of
fledging interstellar powers, both combatants still thought in terms of lines of battle, and the
Romulans thus could not conceive of the kind of free-roaming operations that would retain the
initiative on the defending force. Instead, they mirrored Earth’s desperation from the preceding
years and withdrew from their challenged forward positions to what they considered a defensible
line. By classic Earth doctrines, this called for the uprooting of all UESF defenses and their
utilization for ceaseless assaults that would prevent the Romulans from ‘digging in’. Thus, the
''Ganges'' destroyers were mainly used as perimeter guards for battle fleets in the final phase of the
war.
Still, even in retreat, the Romulans were a threat to colonies and mining outposts: a Romulan unit
cut away from a main force was likely to perform a suicide run at an enemy planet rather than try
and fight its way back to Romulan-controlled space. Local defense missions could thus still be of
essence, and for example the mining colony of [[Lalande 8]] can thank ''USS Tanganyika'' (NDD-1047)
for its continued existence. The ''Tanganyika'' was used as a decoy, luring a suicidal Romulan
auxiliary carrier into ramming an abandoned mining station instead of an inhabited one, as well as
for rendering harmless twelve fightercraft launched by the carrier. ''USS San Esteban'' (NDD-1021)
was the only UESF ship lost with all hands in the final Romulan plunge at [[a Omega B]] in [[2161]],
taking with her two Romulan stormwings but unable to prevent the massacre of more than 20,000
people on the planetary settlement.


In the shadow of the cruisers that dictated the outcome of the war, the story of the ''Ganges'' was one
of forgotten glory. Dull patrol duty along the newly established Neutral Zone awaited [[Starfleet]]
combat forces after the signing of the peace. The compact destroyers were less than ideal for
standing the long vigil far away from planetary surfaces or other fixed assets. A handful were
pressed to intra-Federation traffic protection duties, another few kept for system protection – but as
with many ship types of the Romulan War, no specimen were preserved for posterity. Instead, the
last ''Ganges'' serving under the Federation Starfleet flag were in [[2179]] grounded at colonial starports,
never to be reactivated. As the main threat changed from Romulans back to Klingons in the [[2220s]],
even the best preserved ''Ganges'' were only fit for swift recycling into construction material.

The original destroyer proposal and its competition. Both proposals were designed around the same propulsion system, with the more conventional Vickers destroyer ultimately winning on aerodynamic merits of arguably low relevance.



Note

  • This is referred to as the Neptune class in some fan-canon. In Enterprise, there is an unseen Neptune type survey ship in the UESF, but the images used here match the Warp Delta (so called because of production notes) seen in three Enterprise episodes. Timo originally named the class Iceland; however he updated his Guide to re-name the class Ganges.
