The cybertronian spacecraft relevant to Transformers: Salvation.
The proverbial crown jewels of the Decepticon navy were four massive vessels designated "Fleetcarriers". At approximately twenty miles long each, the Fleetcarriers were the largest spacecraft ever constructed by cybertronain kind, and could- as their name suggested- carry a small fleet of ten more traditionally-sized warships within the immense hangars in their undersides. Add to that ability their vast and powerful arsenals, and the Decepticons had a weapon that only the most daring Autobot leaders would face in battle.
Two of the Fleetcarriers- the Adversary and the Indomitable- were destroyed before the cease-fire was called- the former by the Wreckers, and the latter by Omega Supreme on Junkion. Of the remaining two, Nemesis was the flagship of the Decepticon navy, and when the map to the Omega Lock was discovered, Megatron offered to have the other, Invincible, modified to become a ship that could carry a crew of explorers off into the unknown to find the machine. For roughly three years, both the Autobots and the Decepticons worked together to retrofit the Invincible, combining their technologies, engineering, and craftsmanship. Upon the completion of all the modifications, she was fittingly renamed the Cybertronian Fleetcarrier Salvation.
Signifying the newfound union between factions, Salvation retains the overall silhouette of a Decepticon Fleetcarrier, however the pointy and angular design aesthetics favored by the Empire have been eschewed in favor of the Autobot's considerably less-intimidating and more utilitarian styles. Her black and violet livery has also been exchanged for a sand-colored hull accented by bright red. She is vaguely rectangular in shape, with two downward-angling "fins"protruding from her top to cover her sides somewhat. These fins travel down roughly two-thirds of Salvation's length, before blending into her aft section, which is slightly wider. Though her main hangar has been sealed, Salvation still possesses thirty-two more, of varying size, which house transports, combat spacecraft, and personal spacecraft of various crewmembers. Most of these are located aftward, with the largest, hangars thirty-one and thirty-two, found adjacent to each other at the back of the ship, their apertures facing a wide flight deck that sits almost directly atop her six massive engines. A traveling merchant from Junkion, named Thrift, has set up a small shop in hangar thirty, from which he sells his curios. Salvation's bridge can be found atop a short, wide tower extending from her top, near her bow.
Within Salvation's hull are twelve main decks (identified as Decks 1-12, from the bottom up), each with a few sublevels between them. Each main deck has a plethora of hab-suites to house crew members, a medical bay, a security station, gunnery stations to man some of the Fleetcarrier's weapons in battle, common areas for rest and recreation, and a training facility in which crewmembers can spar either with themselves or drones, or practice their aim on a shooting range. Salvo, the Autobot quartermaster, sells weapons to her fellow crewmembers from an armory beside deck eleven's training room, and Forcep, the Salvation's chief medical officer, can often be found in deck three's sickbay. Most of Salvation's laboratories can be found on deck six, such as the one shared by the ship's head science officers, Sprocket and Grommet. Some of the sublevels also have unique features- sublevel two of deck one, for example, contains a cargo hold converted into a house of worship for particularly devout followers of the cybertronian faith.
As mentioned earlier, Salvation's main hangar has been permanently sealed, and a small population center has been built within it, with towers extending from both the floor and ceiling, roadways, and a few techno-organic parks. Pale lights in the ceiling illuminate this miniature city, which the crew have dubbed "Little Iacon". Its towers hold mostly hab-suites, though a few training rooms and recreational centers can also be found within. Two bars serve as popular hangouts: the Antillian Sunrise, owned by a cheerful nonaligned bot named Halfrunner, and the Peace and Tyranny, run by Lurch, a Decepticon who will only serve members of his faction.
Salvation also boasts a cavernous engineering bay, almost the size of Little Iacon. The Fleetcarrier's main reactor and transwarp drive- which allows her to travel faster than light- hang suspended in its center, branching out to connect to the inner workings of the main engines, which sink into the far wall of the chamber. Gargantuan machinery covers the walls and floor, and catwalks run between it all for the benefit of Salvation's engineers, who reside in towers extending from the ceiling. The chief engineer, Greasemonkey, can often be found in Engineering, tending to the transwarp drive.
An expansive network of maintenance tunnels runs throughout most of Salvation. These are dimly-lit, and retain much of the Invincible's Decepticon architecture. The tunnels have very little security, and as such it is a popular residence for the Fleetcarrier's stowaways, such as Facelift, who makes a living selling his services as a specialist in body modifications, and a small hive of insecticons. Salvation also possesses multiple cargo holds which store energon, ammunition, and other supplies and materials.
Both the Autobots and the Decepticons took the liberty of using Salvation as a test case for many experimental technologies, such as the transwarp drive. It grants her FTL capabilities by allowing her to travel through the void between dimensions, though it must be shut off periodically to cool down and reset; continuous travel through transwarp is sadly impossible. A few of Salvation's weapons are also prototypes, like the forward-facing foldspace warhead batteries underneath her fins, which weaponize the technology of the transwarp drive by ripping open a temporary portal to transwarp space upon detonation, sucking in anything within range. Some of Salvation's other weapons include turrets sporting ion cannons, energon beam emitters, and coilguns. The crux of her arsenal is a massive warp cannon built into her prow. Devised by the likes of Ironhide, Wheeljack, and Triggerhappy, its destructive capabilities are currently unknown, though undoubtedly immense. Salvation's pilot, Flyby, has yet to find a situation in which to put the cannon to use, though when that chance comes, it is likely to be a great spectacle.
For a better visual reference for Salvation, imagine a cross between the Nemesis from Transformers: Prime and Halo's Spirit of Fire, with the details described above. The overall silhouette is similar to that of the Nemesis, with the Fire's influences added to remove most of the "pointy bits" and make her look less threatening/evil.
The Inquisitive Savant is- or was- a deep-space research vessel, one of many built by the Knights of Cybertron in their ongoing commitment to exploring the universe. While its few weapons outclass many found on modern cybertronian military craft due to their advanced design, Savant's true strengths lie in her scientific equipment. Her sensory suite makes Salvation seem blind by comparison, and the Fleetcarrier's laboratories, refineries, and other related facilities are woefully primitive next to those aboard Savant... if Savant was still functional, that is.
Unfortunately, long-lasting though Golden Age technology may be, it is not immune to the effects of the elements and the march of time. Savant has spent the better part of one hundred million years drifting within a small binary star system, and has suffered extensive damage throughout her frame. Barely a fraction of her equipment and datatrax are currently accessible, and it seems unlikely that Salvation's crew will be able to enact significant repairs to remedy that.
All the same, Inquisitive Savant may yet be of some use to our heroes. The navigational data recovered from her computers will surely unveil many points of interest to investigate as the quest to retrieve the Omega Lock continues, and some of her equipment may still be salvageable. Knight vessels are also known for their numerous secret rooms and passages, and were also reputed to contain advanced AI- a science largely lost following their mysterious disappearance- though it is currently unknown if Savant possessed one of her own.
The Inquisitive Savant can be found docked within hangar thirty-one of the CFC Salvation, and all are free to explore and see what they can find. Sprocket, a specialist in Golden Age technology, will surely reward handsomely anyone who brings him something of interest from the derelict.
The Twenty-sixth Decepticon Fleet
The Twenty-Sixth Decepticon Fleet is one of the largest and most formidable in the Decepticon Empire's navy, and has fallen under the leadership of Bludgeon in his bid for the Omega Lock and its divine power. Technically, though, it is still under the command of Thunderblast, who assumed the position after the previous incumbent tragically lost his life in a "freak accident".
Thunderblast commands from the Vigilant, an immense and heavily-armed warship which resembles the Animated cartoon's depiction of the Nemesis. It is roughly three miles in length, and possesses three fusion cannons protruding from its back half, in addition to other weapons. It carries swarms of fighters and a hefty compliment of airborne Decepticons, and can deploy ground forces to be commanded by Obsidian and Strika.
Five supply ships maintain the Twenty-sixth's reserves of energon, ammunition, and other important resources. They collect resources that the heretic Decepticons find while pursuing Salvation, and possess refineries, manufacturing plants, and laboratories. They are each roughly a quarter the size of Salvation, and are armed almost exclusively for defending themselves from attack- said armaments include four small fusion cannons situated around the bridge. They each resemble the Decepticon ship Leviathan from the Universe online game.
Ten assault ships constitute most of the Twenty-sixth's might. Each is armed to the proverbial teeth and built specifically to engage enemy warships in combat. While individually they may be no match for Salvation's weaponry, together they may very well pose a threat to her. They resemble one of the movieverse's Nemeses as depicted in the tie-in comics.
Seven carriers contain the bulk of the heretic Decepticon's ground forces. They are each two miles in length- their size mainly being for housing troops, weapons, and vehicles- and are armed similarly to the assault ships. They resemble Fall of Cybertron's Nemesis.
Eight mercenary vessels of varying size, arsenals, and designs bolster the Twenty-sixth's numbers, their crews hired by Bludgeon with the help of Banzaitron and Lockdown. The most notable of these is the Death's Head, the personal starship of the infamous Lockdown. Only he is privy to its specifications, though rumors from the plausible to the preposterous are abound concerning its history, weapons, and other capabilities.
Finally, Bludgeon's own Super-worldsweeper, the Armageddon, accompanies the Twenty-sixth's on its treacherous mission. Nearly ten miles long, the Armageddon bears the silhouette of a traditional Worldsweeper, though is much larger and possesses more devastating weapons- such as a beam cannon built into the prow that can slice up a traditional warship like a cake. It bears predominantly blood-red armor, with copper highlights and orange exterior lights. It resembles IDW's Worldsweepers in design.
