As an Imperial-class Star Destroyer, the Conquest was 1,600 meters long. It was additionally equipped with two deflector shield generator domes on the command tower, a communications tower between them, three Destroyer-I ion engines, and four secondary Gemon-4 ion engines.
The Conquest served in the Imperial Navy of the Galactic Empire during the Galactic Civil War. In 3 ABY, Project Swarm was initiated by the Imperial Death Squadron to locate the Rebel Alliance's main base. When a probe droid discovered the base on the ice planet Hoth, Death Squadron was located in the near Qeimet in the Juris sector. The Conquest was part of the squadron, alongside the Star Destroyers Avenger, Devastator, Stalker, and Tyrant, which were all led by Darth Vader and Admiral Kendal Ozzel from their flagship, the Executor-class Star Dreadnought Executor. The squadron was then deployed to the Hoth system, with the Avenger, Devastator, Stalker, Tyrant, and the Star Destroyer Ultimatum participating in the Battle of Hoth and its direct aftermath, which included the squadron chasing the Millennium Falcon through the Hoth asteroid belt. The pursuit resulted in destruction of the Conquest, as well as the ISD Ultimatum, and the Falcon successfully escaping to the nearby world of Bespin.
