The Imperial-class Star Destroyer (ISD) known generally as the Imperial Star Destroyer, was a product line of massive dagger-shaped capital ships of the Imperial Navy and later the Navy of the First Order. It consisted of two variants, the Imperial I-class Star Destroyer and the Imperial II-class Star Destroyer.
At the height of its power, the Galactic Empire operated over 25,000 of these ships. The distinctive profile of the Imperial-class instilled fear into the soldiers of rebelling factions, and the name of a Star Destroyer could be preceded by the ship prefix ISD (for Imperial Star Destroyer). In a report to an admiral, Senior Commander Alecia Beck referred to the ISD Vehement.
Roughly thirty years after the Battle of Endor, the new Resurgent-class Star Destroyer would be constructed to replace the aging Imperial-class by the Empire's first successor state, the First Order, and would borrow design philosophies from the highly respected ship.
