Aramadia - class thrustship The " Aramadia " - class thrustships , also called T - types or Fat Men by the New Republic Defense Fleet , were the main combat vessels of the Yevetha n space forces . Characteristics . The Aramadia class was a 240 meter diameter spheroid with six Aradian pulse - lifter s arrayed in an inverted triangle at its stern . It was from these pulse lifters that the ship earned its designation as a " thrustship " . The ship was armed with eight turbolaser batteries mounted on an internal shift - track spaced around the ship . Advanced targeting systems allowed for up to four batteries to link their fire and concentrate it on a single target . Despite the punch the link batteries could provide , its major combat payload laid in its projectile launching capability . It carried three proton torpedo launchers , a centrally mounted gravity bomb launcher with four bombs per load , and four ten - tube missile batteries . Overall , the weapon systems earned it a grade of medium cruiser . The Aramadia class also benefited from superior shielding . The ship ' s spherical shape enhanced the shield generators ' ability to provide smooth coverage , allowing for maximum shielding with minimal power . These ships carried 40 Yevethan D - type trifoil fighter s . History . The thrustship designs were developed by the Yevetha of the planet N ' zoth . Their early designs consisted of sub - light vessels which they used to form the Duskhan League and consisted of twelve colonies before the Galactic Empire enslaved the race . After the Battle of Endor , the Yevetha rose against the Imperials and managed to capture the entirety of the Black Sword Command . Using the Star Destroyer designs , they supplemented the Black Fleet with their own thrustships which they built hundreds of in order to wage a campaign against the alien inhabitants of the Koornacht Cluster for the purpose of eradicating them . As the technical skill of the species advanced , the Duskhan League modified their thrustships thus providing them with the means for hyperspace travel . One such thrustship , known as the " Aramadia " was used as Viceroy Nil Spaar ' s personal transport during a diplomatic meeting with the New Republic on Coruscant . The negotiations were , however , only a ploy for Spaar to determine the strength of his foes and orchestrate a political incident in order to turn the political system of the New Republic against Chief of State Leia Organa Solo . This included the Aramadia blasting off from Coruscant in order to give the appearance of " " escaping " " from the tyranny of Princess Leia . Hundreds of thrustships were later used by the Yevetha during their secretive Great Purge of the Koornacht Cluster . Such ships were used to exterminate alien populations and colonize them with Yevethan settlers . After the capture of General Han Solo , Nil Spaar attempted to persuade the Corellian to convince Leia Organa Solo of the futility of further conflict by showing hundreds of thrustships under construction on N ' zoth by the Nazfar Metalworks Guild . He further stated that further such vessels were constructed on the other worlds in the Yevethan Protectorate and that the Yevetha would not relent in their actions , but this failed to dissuade General Solo . Later , as conflict began to grow between the Duskhan League and the New Republic , the thrustships were used as a primary warship during the Black Fleet Crisis until the Yevetha ' s defeat at the Battle of N ' zoth . After their defeat , the Yevetha began their attempts at rebuilding their fleet which included countless new thrustships in their forces . However , during the Yuuzhan Vong War , the extragalactic Yuuzhan Vong were alerted to the threat of the Yevetha by the Fia from Galantos . This led to the brutal invaders attacking and eliminating the Yevetha forces , annihilating the species and leaving countless hulks of burning thrustships in orbit around N ' zoth .
