Historia Hyperion: The Most Wanted Battlecruiser.
Flush with cash after the Guild Wars, the Confederacy began investigating a series of upgrades for the splendidly well served Behemoth-class Battlecruiser, which would culminate ten years later with the first Yamato canon prototypes. Because this project was very experimental however, a testbed ship was needed, and the under-construction Behemoth General Lee was selected for upgrades and structural reinforcement to supply it with the durability and backup power supplies needed for an experimental ship. Confederate graft and corruption soon made the procurement of the General Lee's components a matter of some disagreement and, while the exact reasons have been lost, the ship was fitted while under construction with a Warp Drive of unusual design and power was made central to the design. While almost every other feature of the new battlecruiser was made modular, this one key piece was locked in more solidly than normal, and indeed, the ship's structure was arranged so that the warp drive couldn't be removed without first cutting the ship's main structural spine in half. The warp drive itself was the first and only one of it's kind ever built, the J-5700. The Confederacy had taken a great risk on this engine type, designed by a team of ambitious scientists rather than the normal procurement channels, based entirely on their promise of it's capability. According to it's makers, the J-5700 would be the first warp drive to drastically improve over the drives used by the old colony ships, giving the Battlecruiser the ability to jump much deeper inside gravity wells, and to navigate much more accurately, opening up tactical use of the warp drive. As the Ship underwent fitting out, this feature, above all others, dominated the ship's scuttlebutt and the focus of attention.
Unfortunately for the Confederacy, the ship's first captain, one Commodore Arthur Smythe, was a strong believer in the power of his new ship, and eager to demonstrate it with a 'rock and roll' cruiser through Umojan space where he would violate sovereign territory and invite reprisal with impunity. Smythe's first jump was towards the Umojan asteroid colony UMS-3984K, and upon exiting warp the Battlecruiser collided directly with the asteroid, smashing the bridge and instantly killing Commodore Smythe thanks to both the sudden stop as his head slammed into the rocks, and the total lack of air. Incredibly, the misjump had not shattered the battlecruiser into a thousand pieces strewn across the surface of the asteroid, and had instead come *almost* to a complete stop, *mostly* intact. Umojan salvage teams swiftly moved in and were able to both effect rescue operations and begin the process of towing the bent, but not broken battlecruiser back into their shipyards. The crew's survivors were well fed and pumped for information over several months, as the Umojans patched up and further upgraded with damaged ship. The ship's navigation lieutenant, Pollock Rimes, provided a partial account of the ship's warp drive and final jump-Rimes hadn't been on the bridge but had lost his front teeth and gains several nasty scars in the accident. At the same time, the Confederacy declared the entire 2000 man crew MIA, when in fact, only 300 were dead and the reamander were trying to get back from Umoja or accepting new jobs in the Protectorate.
The Protectorate Naval Service however, found that they were ill-equipped to tend to a Behemoth-class Battlecruiser, especially one so experimental. There was much to learn from the ship, but it was also a hodgepodge of graft, corruption and simply non-functional systems. As she was found, the ship had no weapons able to fire at an exactly flat broadside, she always had to roll her hull so the top or bottom turrets could bear on the target. The cavernous interiors were also somewhat sparse once you left officer country, with no less than 12 major landing bays. The ship had no role in Umojan doctrine, though their navy was eager to learn what it could. When that was tapped out, the ship was offered, along with the crew who had not taken other jobs, to a visiting Arcturus Mengsk. It was in fact, to obtain his new flagship, that Arcturus brought much of the Korhal treasury to Umoja with him when the planet was destroyed-and a sale became an indefinite loan to the Sons of Korhal. Mengsk re-named his ship Hyperion for an ancient titan who was a father of gods, fitting his own classical mythological taste in names for ships. Over the next nine years, Mengsk employed Pollock Rimes as the ship's flag captain, giving him broad instructions but generally avoiding fights. The J-5700 engine was given only rare workouts during this time, as the Sons of Korhal didn't have the documentation to repair it and also didn't trust it after it's first disasterous test. Famously, in one clash with the Norad II, Pollock Rimes let himself get blocked by the other battlecruiser, unable to jump to warp without ramming the other ship and destroying both of them. Shortly thereafter however, Rimes was outed by Sarah Kerrigan as a confederate mole, who had been passing data on the Sons to the Confederate military in exchange for potential clemency and generous benefits to his family.
After 2500, the Hyperion actively, though rarely participated in the Great War, as the Terran Confederacy began to break down under Zerg attacks and the Sons' actions. At Mar Sara, it engaged briefly a Confederate Blockade group to clear the way for escaping colonists, while at Brontes, the Hyperion was damaged by the Norad II's Yamato cannon and lost 150 crew, but managed to limp away due to the sturdy Umojan refits, and was out of combat for the Antiga Prime Campaign, where Norad II was lost due to Scourge attacks that overwhelmed it's lasers and missile pods. With the final assault on Tarsonis beginning, Mengsk brought the fleet to Tarsonis in good order, with the Hyperion coming along mostly as a command post instead of a combat vessel. As the Psi Emitters were being placed, one of Mengsk's scavengers found a set of new experimental equipment for Battlecruisers, and a hastily built dock just large enough for a single ship to undergo refits in. As the Protoss and Zerg entered the system, Mengsk took the time to have his flagship dock with the orbital platform and begin to take on all the lovely toys it had never before been equipped with-rapid fire lasers designed to deal with Scourge, heavier laser batteries for improved combat ability, and a Yamato Cannon of his very own. There were even technical manuals, over twelve years old, for the Hyperion's temperamental engines. For the time being however, this meant that the Hyperion lost it's status as flagship while Mengsk transfered his command to the Norad II.
Command of the Hyperion under her refit was confused and a recently arrived Matt Horner was able to secretly move members of Raynor's Raiders into place on the ship while the rest of the group hit the Ion Cannon. By the time the Raiders destroyed the cannon, however, Norad II and the rest of the fleet were moving to pin them in, as Hyperion finally moved out of dock-and flicked her IFF from Dominion Red to Raider Blue. Confident in his ability to take Hyperion again, General Duke moved Norad II to block it's escape as he had done almost a decade earlier. Matt Horner was not like previous captains of the Hyperion however, and as the raider's transports moved into dock, he slowed the drive and began a slow, erratic fire to drive off Wraiths and other pursuers while he lined up his thesis. Rather than attempt to escape directly, Lieutenant Horner, a navigator by training, and precise by his natural inclination, lined up the J-5700 for an unprecedented in-system jump. What has come to be known as Horner's Doughnut saw the Hyperion jump into a twisted abortive warp-jump that landed him firmly *behind* the Norad II, with his new Yamato cannon firmly pointed up the aft of the other ship and neutralizing one of it's engine clusters in a single shot before breaking off and escaping. Unlike every other commander of the ship to date Matt Horner has firmly embraced the possibilities of the J-5700 and makes frequent use of it in combat, jumping much closer to planets on raids, and much more accurately into combat situations. The Raiders have since used the Hyperion to raid the Dylarrian shipyards ahead of the Dominion establishing control there, to launch their own invasion of Char, and most astonishingly of all, have taken their ship to the Protoss Homeworld, thousands of light years away from the Koprolu sector, making the Hyperion the most-traveled ship in modern Terran history.
Emperor Mengsk offers a 30 million credit bounty for the return of his once and hopefully future flagship.
