The Vengeance-class dreadnought was a dreadnought-scale warship in the Imperial Navy. 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. Based on the original Executor Super Star Destroyer design and customised to meet the specific requirements of Inquisitor Jerec, construction of the Vengeance, named after the Dark Jedi’s former command, began shortly before the Battle of Hoth. Although the same length as the more common Executor the Vengeance was easily recognised by its strikingly slender frame and almost sword-like appearance which contrasted strongly with the dagger-shape standard on most Star Destroyers. Originally believed to be unique to the Inquisitor several other examples of this class were later identified as part of the Reborn Emperor’s Byss fleet.
