Other Types
Victory-class Star Destroyers appear as early as Brian Daley's 1979 book Han Solo's Revenge, and since then have appeared in Expanded Universe books and games. Designed by Rendili StarDrive in the Star Wars universe, the Victory-class is 900 meters long and features fewer weapons and cargo space than an Imperial Star Destroyer.
Venator-class Star Destroyers, also known as "Republic attack cruisers", appear in Revenge of the Sith and in the Expanded Universe. The ship's design is meant to bridge the appearance of the Acclamator-class transports in Star Wars Episode II: Attack of the Clones and the Imperial class in the original trilogy. While the ships first appear with a red and grey Republic color scheme, the Venator at the movie's end is gray and white; this lack of color signifies the Empire's rise to power.
