The Executor-class Star Dreadnought Executor was the personal flagship of the Dark Lord of the Sith Darth Vader and one of the largest and most powerful Imperialvessels ever constructed. Under Vader's command, the Executor led the Death Squadron following the Battle of Yavin and oversaw the Imperial assault on the Rebel Alliance's Echo Base during the Battle of Hoth. While serving as the Imperial command ship during the Battle of Endor under Admiral Firmus Piett, the Executorwas destroyed after a wayward Rebel A-wing starfighter piloted by Arvel Crynydcrashed into its bridge, causing the Super Star Destroyer to lose control and smash into the Death Star II.
