The Imperious-class Star Destroyer, also known as Advanced Star Destroyer,[1] was the designation given to the Imperial Star Destroyer Imperious, which was built during the Second War for the Imperialist Navy and later the Federal Navy. The Imperious-class was designed to make use of several especially large thrusters and sported a 'tailfin' similar to those of the Star Destroyers of the Galactic Republic. The class' command bridge was very similar in design to those of most Kuat Drive Yards warships, while spaced in pairs on its sloped superstructure were several towers of unknown purpose.
