The Executor-class Star Dreadnaught are the largest warships built for service in the Galactic Empire during the Galactic Civil War. The first ship, the Executor, is Darth Vader's flagship of the Galactic Empire. It carries millions of stormtroopers, officers, and gunners. It has over a million Turbolasers, and laser cannons as well as a tractor beam, and it holds a complement of millions of TIE Fighter, Interceptors, Bombers, Boarding Crafts, Landing Crafts and Shuttles.
The Executor was only one of several ships of this class built. Other ships include:
- Lusankya - Built as Palpatine's escape ship, used as a private prison for Ysanne Isard, and later became Isard's flagship during the Bacta Wars. It was captured and became Wedge Antilles' flagship until it was destroyed during the Yuuzhan Vong War.
- Annihilator - A ship serving in the Kuat system under the command of Admiral Gaarn. It was destroyed by the Zann Consortium in a battle shortly after the Battle of Endor.
- Reaper - The flagship of Grand Moff Ardus Kaine, the leader of the Pentastar Alignment (an Imperial splinter faction formed in the years following the Battle of Endor). It was destroyed at the Battle of Celanon.
- Brawl/Iron Fist - Warlord Zsinj's flagship. It was destroyed by Han Solo and the Hapan Royal Navy at Dathomir.
