Vengeance - class dreadnought The " Vengeance " - class dreadnought was a dreadnought - scale warship in the Imperial Navy . Characteristics . Dimensions . The " Vengeance " - class was based on the standard Super Star Destroyer design , the " Executor " - class . As such , the ship class was approximately 19 kilometers long . In addition , because of its dimensions , the ship class sometimes possessed the standard classification of a space station In contrast with the " Executor " - class , the " Vengeance " - class ' s frame was supplied with a slender build , more narrow than standard Star Destroyers , almost sword - like in comparison to the usual dagger shape . The " Vengeance " - class ' s height contrasted its length , which was little more than 150 meters and with downward sloping armor dominating most of the dorsal frame . The ship class ' s bridge was extensive , but also covered much of the command tower , unlike most other KDY warship classes . 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 the ship class it belonged to had armaments similar to Star Dreadnoughts of the " Executor " - class . Propulsion systems . The " Vengeance " - class 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 " - class , except that they carried a number of TIE / LN starfighter s and assault shuttles . Command bridge . The " Vengeance " - class 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 . It shared this trait with the " Praetor Mark II " - class battlecruiser . History . The " Vengeance " - class was one of several heavy capital ship classes made after the " Executor " - class Star Dreadnought . The flagship of the Dark Jedi and Imperial Inquisitor Jerec was a dreadnought of this class named the " Vengeance " . It was used from some time before the Battle of Endor to the time of his death in 5 ABY . Several " Vengeance " - class dreadnoughts were apparently utilized by the Byss Defense Fleet . Three " Vengeance " s anchored massive task forces sent from the Deep Core to reconquer the Core Worlds in 10 ABY . One of which , the " Javelin " , was destroyed during the subsequent Imperial Civil War when its captain steered it into a Torpedo Sphere that guarded Chasin . Behind the scenes . The " Vengeance " - class dreadnought first appeared in " The Essential Guide to Warfare " , alongside a ship within its class , 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 .
