Another SV from me, this time a fixed wing aircraft. For those that might recognize it my Frog is based on the US DoD Advanced Tactical Transport. I can't get my drawing of the Frog to work so if you want to see it it is posted over on the CBT boards here ==>http://forums.classicbattletech.com/index.php/topic,13856.0.html


Fire team leader Corporal André "le Buef" LeBeau glanced up when the cabin lights suddenly shifted from white light to red.

Won’t be long now. Thank goodness. After three hours in that cramped cargo bay CPL Le Beau was ready to jump.

About ten minutes later the Amber Light flashed once then stayed lit. Within seconds the Jumpmaster was on his feet and gave the stand up signal for everyone else to do the same; it was much too loud in the aircraft’s cargo bay to be heard shouting down its whole length.

Almost in perfect unison the troops stood up. That’s when it would have become clear to any outsider why "the Bull" was called "the Bull." CPL Le Beau was almost a head taller than everyone else in the bay, and half again as wide. He was easily big enough to wear battle armor.

Then, like a well choreographed ballet, cliché though it was, the jump troopers began one final equipment check before the jump. CPL Le Beau checked the front of Private Benjamin, his Number One Rifleman, going over her gear and harness quick but carefully. She then did the same for CPL Le Beau, standing almost on her tiptoes to check his shoulder straps. Then she turned around so CPL Le Beau could check her back. After the back check CPL Le Beau slapped her on her right shoulder, signaling "inspection satisfactory" and did an about-face so she could check his back. The inspections took about a minute.

A minute or so later the Amber Light flashed twice, signaling the Jumpmaster, Assistant Jumpmaster, Aircraft Loadmaster and Aircraft Crew Chief to walk down the length of the bay to the jump doors: Jumpmaster and Loadmaster on the port side, Asst. Jumpmaster and Crew Chief on the starboard. As they went the jumpmasters were getting the Ready-to-Go signal, the universal thumps up, from everyone as they walked by.

Once the quartet reach the jump doors the Crew Chief and Loadmaster both hooked up their safety harnesses to anchor points near the jump doors; after all it wouldn’t do to have an over exuberant soldier drag either one of them out the door. They then opened the jump doors as the jumpmasters signaled for proper line up for jump, as if anyone needed to be told.

Seconds later the Amber Light flashed once then went out. Ten seconds. CPL Le Beau watched, in a half crouch, ready to bolt for the door as the Crew Chief, and doubtless the Loadmaster on the other side of the bay, signaled the countdown. Five. Four. Three. Then the Red Warning Light joined the countdown. One flash. Two. And three times. Go! Go! Go! CPL Le Beau could actually hear they jumpmaster yell "Go!"

But he had scant time to realize it as he headed for the door and jumped. The jump pack’s gyros then kicked in, helping him stabilize his flight. CPL Le Beau didn’t give the Super Frog transport a second thought as he prepared for the coming fight.



The Federated-Boeing SA-8 Frog Small Tactical Transport

Conventional fixed wing aircraft, though much rarer in terms of absolute numbers than ground vehicles, have always been very important to military operations, at least since their invention. Even when the aerospace craft that would eventually be known as small craft and DropShips came on the scene conventional fixed wing aircraft did not entirely disappear from military operations. They were simply too inexpensive compared to their aerospace brethren to ignore completely, so when the Succession Wars era came to the Inner Sphere many manufacturers still had the engineering expertise, and facilities to manufacturer them.

Given that, it is no surprise that Federated-Boeing, a firm founded originally to design and build fixed wing aircraft, is still one of the largest, and most well regarded firms in a rather crowded market offering designs for just about ever niche one can imagine.

One of Federated-Boeing’s best selling designs is its SA-8 Frog, which is roughly a quarter the size of their SA-10 Swallow. The Frog, named for its rather ungainly takeoff and landing profile is built specifically as a military small tactical transport although it is used more often in civilian transport service than military service. The Frog is designed around a 20-ton cargo load with the intention of moving it on short hops of a few hundred up to a thousand kilometers. It is designed to use the most basic, rough airfield facilities as well, being equipped with a tilt-wing VSTOL system and a reinforced airframe capable of absorbing enormous punishment.

Although it is rather commonplace today Boeing refined the original tilt-wing concept centuries ago. The wing actually pivots to a maximum of 45 degrees to maximize the thrust pushing down, lifting the aircraft. One characteristic of many fighter aircraft and aerospace craft, but unique to Boeing fixed wing transport aircraft is its lack of a vertical stabilizer or horizontal elevators. Their transports utilize sophisticated redundant control systems, as well as highly refined aerodynamics to keep the aircraft in flight. Boeing’s safety record over the years have proven repeatedly that the design concept is sound and reliable even though some people still find it a little disconcerting to fly on an aircraft that doesn’t look right.

The Frog’s wide body and wide cargo bay allows the Frog to carry much greater volume of stores or equipment than many of its competitor designs, although the Frog is still nestled within the 20-ton carrying capacity niche. The bay measures a full 12 meters long and 5 meters wide with a 3 meter ceiling, can easily accommodate up to 105 jump infantry or paratroopers and is designed and frequently used for theater airdrops thanks to jump doors towards the rear of the bay on either side. The aircraft is also equipped with a rear ramp so vehicles and cargo can easily be driven in, or out. Pallets of cargo can even be dragged out while in flight. In fact, one of the Frog’s specialties is the drogue chute low altitude deployment technique to deliver cargo. Basically a small parachute drags a pallet out of the aircraft as it flies a scant 3 meters above the ground, just above stall speed, the cargo actually drops the 3 meters as the chute is just used to arrest the pallet’s forward motion. The maneuver can be dangerous but is very useful for resupply operations.

Although the Frog is enthusiastically used throughout the AFFS by march and planetary militias, and not a few regular army units, the majority of Frog transports are flown by civilian air freight services throughout the Federated Suns and neighboring realms as their are no export controls on the demilitarized Frog model Air freight companies that most frequently use the Frog service remote communities that are not well connected to ground transportation infrastructures. Most military Frogs are used for mundane air freight duties, just like their civilian counterparts, and are generally assigned to garrison units. Most airdrops conducted by Frogs, and similar aircraft, were therefore defensive in nature. However during the Fourth Succession War several airdrop missions and many, far more numerous air freight missions were conducted by Frogs on captured worlds, post initial planetary assault. The aircraft were shipped in to free up more aerospace assets for space-based transport and assault duties.

The current production models of the Frog are the SA-8-700C & 700M. These models were introduced in 3020 and improved on the 600 series by adding new engines, with longer life expectancies, switching to a newer composite armor, more useful against bird strikes than weapons, and revised the trailing and leading edge flap designs so they can use more commonly available parts.

Without doubt the SA-8 Frog is an excellent example of Boeing engineering, even if it loses the limelight to more sexy aerospace craft.

Hey Boilerman, I like these SV's you're posting. Where did you get the SV rules from to create them?

Thanks Jimmy. The Support Vehicle Construction Rules are in Combat Equipment and also will be in TechManual, along with some corrections and clarifications to the construction rules.

Doc pointed out a problem with the VSTOL chassis and control modification on a Th2/3 aircraft, so I switched the Frog to a STOL chassis and control modification.
