At the height of its power, the Empire operated over 25,000 Star Destroyers. The distinctive profile of the Imperial-class instilled fear into the soldiers of rebellious factions, and the name of a Star Destroyer could be preceded by the ship prefix ISD (standing 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 Destroyers were constructed to replace the aging Imperial-class by the Empire's successor state, the First Order, and would borrow design philosophies from the highly respected and coveted ship.
