Vengeance ( Vengeance - class ) The Vengeance was a slender , black KDY Super Star Destroyer that served as the flagship of the Dark Jedi Jerec in the years before and after the Battle of Endor . It was commanded by Captain Sysco . Characteristics . Dimensions . The " Vengeance " was based on the standard Super Star Destroyer design , the " Executor " - class . As such , the " Vengeance " was approximately 19 kilometers long , and was named after the Dark Jedi ' s old Star Destroyer , which he commanded some time prior to the Battle of Yavin . In addition , because of its dimensions , it sometimes possessed the standard classification of a space station The most striking feature of the ship was its slender frame , which was more narrow than standard Star Destroyers , almost sword - like in comparison to the usual dagger shape . The " Vengeance " height contrasted its length , which was little more than 150 meters and with downward sloping armor dominating most of the dorsal frame . The ship ' s bridge was extensive , but also covered much of the command tower , unlike most other KDY warships . It is known that it was one of the larger Super Star Destroyers of the Imperial era , and its length ( exceeding 5 , 000 meters ) put it firmly in the Star Dreadnought category . Offensive and defensive systems . The " Vengeance " was only shown defeating a small , probably unmanned CR90 corvette , but it had armaments similar to Star Dreadnoughts of the " Executor " - class . Propulsion systems . The " Vengeance " had a cluster of engines , consisting of three primary engines , two secondary engines flanking the vessel and six auxiliary engines clustering around the primary ones . Complement . Little is known about the capabilities of the " Vengeance " , except that it carried a number of TIE / LN starfighter s and assault shuttles . Command bridge . The " Vengeance " was unique in that it lacks the standard Kuat Drive Yards - style wedge shaped command bridge tower . Instead , the command bridge is located on a small square ridge near the stern of the ship . History . To accommodate Jerec ' s increasingly large ego , he had a personal warship built to be his new command ship . The vessel began construction some time before the Battle of Hoth , as Jerec donated his " Vengeance II " to Admiral Kendal Ozzel ' s Death Squadron while waiting for the larger vessel to be finished . Jerec used the " Vengeance " as a meeting place for him and his Dark Side Elite in the following years . The ship also served as flagship for the Vengeance Battle Group , an Imperial military formation which aided Jerec in his search for the Valley of the Jedi . Some time after the Battle of Endor , Jerec used it to travel to the planet Dorlo . There , he sent down a task force led by his Dark Jedi underlings to find and capture the fugitive Jedi , Qu Rahn . The ship was last seen orbiting Ruusan , the location of the Valley of the Jedi . The battle group it led seemed to represent a relatively common force composition , judging from the reaction of New Republic operative Alfonso Luiz Obota , who observed the group during the Mission to Ruusan in 5 ABY . Three " Vengeance " - class dreadnoughts , mass - produced versions of Jerec ' s flagship , participated in the retaking of the Core Worlds and the subsequent Imperial Civil War . In 10 ABY , various " Vengeance " - class dreadnoughts were seen near Byss , during Emperor Palpatine ' s Operation Shadow Hand campaign . Behind the scenes . In " The Essential Guide to Warfare " , there was a mention of the " Vengeance " - class dreadnought as well as the " Javelin " . Although artwork of it was never shown , the name of the ship class suggested a connection to Jerec ' s flagship of the same name . A post made by Paul Urquhart on the TEGTW forum for TheForce . Net revealed that the similarities and connections between the ship class and Jerec ' s ship was intentional .
