A Star Destroyer was a dagger-shaped type of capital ship that were used by the Galactic Republic, the Galactic Empire, the First Order, and the Sith Eternal.

Notable examples of Star Destroyers include the Imperial-class Star Destroyer and its predecessor the Venator-class Star Destroyer.

According to Everi Chalis, Star Destroyers were the most resource-intensive ships the galaxy had ever seen, and only Kuat possessed shipyards that were capable of supporting and maintaining more than a handful at a time.

Thirty years after the Battle of Endor, the barren surface of Jakku was still littered with the wreckage of countless Star Destroyers. These derelict starships were regularly targeted by scavengers such as Rey. The First Order, a remnant of the Old Empire, was also known to utilize Star Destroyers as part of its fleet, such as the First Order’s Resurgent-class Star Destroyers, which were inspired by the dagger-shaped design of the Old Empire’s vessels.
