Imperial-class Star Destroyer

The Imperial-class Star Destroyer (ISD) known generally as the Imperial Star Destroyer or as an Impstar, was a product line of massive dagger-shaped capital ships of the Imperial Navy of the Galactic Empire and later the naval branch of the First Order. The successor vessel to the Venator-class and Imperator-class Star Destroyers, it consisted of three designs: the Imperial I-class, the Imperial II-class, and the Interdictor-class.

At its height, the Empire operated 25,000 Star Destroyers, with twenty-four assigned to each of the Empire's 1,024 Sector Groups. The Imperial-class became the backbone of the Imperial Navy, hunting down Rebel Alliance task forces, blockading unruly worlds and serving as launch bases for planetary assaults.
