The Imperial-class Star Destroyer Mark II, also known as the "ImpStar Deuce", is a Star Destroyer model that was derived from the Imperial-class Star Destroyer. The class began with the prototype Imperial II known as Empire, commanded by Admiral Feyet Kiez. The first operational ships of this class began to appear in service several months after the Battle of Yavin. Several Mark I's have been upgraded into Mark II's since their introduction.
