The predecessor of the fearsome and ubiquitous Imperial-class, the Victory-class Star Destroyer saw the height of its production in the beginning of the clone wars, filling the need of the Old Republic for a capital ship capable of fulfilling multiple combat roles. The unique, dagger-shaped design of the Star Destroyer allows the Victory-class to concentrate nearly all of its weapons on its front firing arc. This ingenious design has since been copied in every subsequent design of the Star Destroyer by the Empire.
While only little more than half the size of the Imperial-class, the Victory-class Star Destroyer mounts 120 turbolasers and 20 proton torpedo launchers, giving it more offensive punch than its larger cousin. Both troop berths and hangar space were sacrificed in order to mount the additional weapons on the hull, making the Victory-class Star Destroyer a dedicated ship-to-ship combat vessel whereas the Imperial-class is able to serve many more functions in the Imperial Navy.
After seizing galactic power after the fall of the Old Republic, the Galactic Empire kept the Victory-class in service and even continued to build the vessel, updating and refitting its secondary systems as necessary. In addition to the Empire, several other governments and even some private citizens are known to have acquired some of the fearsome vessels which made their way out of the Republic Navy during its transition to the Empire.
