The Imperial I-class Star Destroyer was a model of Imperial-class Star Destroyer in the service of the Imperial Navy. A wedge-shaped capital ship, it bristled with weapons emplacements, assault troops, boarding craft, and TIE line starfighters. In the era of the Galactic Empire, its command bridge was staffed by the finest crewmen in the navy.

At first, Star Destroyers were deployed to sectors and systems caught in the aftermath of the Clone Wars, where they would crush any signs of sedition. During the Galactic Civil War the Destroyer’s role changed to hunting down high value Rebel targets and bases. They fought in notable battles such as the Battle of Hoth and the Battle of Endor. The Imperial II-class Star Destroyer was a derivative of the Imperial I-class.

The Resurgent-class Star Destroyer, also known as the Resurgent-class Battlecruiser, was an iconic model of battlecruiser and Star Destroyer built by Kuat-Entralla Engineering. It saw service in the First Order Navy in the Unknown Regions after the signing of the Galactic Concordance. Based on the Imperial-class Star Destroyers of the Galactic Empire, it featured advanced weaponry and extreme size and represented the might of the emergent First Order throughout the galaxy. The First Order Star Destroyer was still considered a new model by 34 ABY.
