||The Executor-class Star Dreadnought, colloquially known as the Executor-class Super Star Destroyer, Executor-class Star Destroyer or simply Super Star Destroyer, was a heavy warship class in the Star Dreadnought league, often used as command ships and flagships in the Imperial Navy. At their prime, they were among the largest vessels in the galaxy, and were almost invincible in combat, although they were costly to operate. Like most KDY-style warships, the ship's overall shape was pointed, although unlike the Imperial-class, the Executor-class was closer to dagger-shaped. It also retained the KDY-style command bridge and possessed a massive cityscape on the top and, to a certain degree, at the aft. Its primary colors were dark gray and white for the main hull, and black for the cityscape sections, although the various lights aboard the vessel combined with operating in deep-space environments at times gave a more cerulean appearance to its hull. The Executor-class measured 19 kilometers in length and was 100 times more massive than the ubiquitous Imperial-class Star Destroyer. 280,734 Imperial Navy officers, gunners and enlisted men were said to have crewed each vessel.
Though several variants of the Executor-class existed, all followed similar design attributes in terms of structure. In terms of length, it was also tied with the Vengeance-class dreadnought as the largest ship class within Star Dreadnoughts or Super Star Destroyers.
