The Executor was an Executor-class Star Dreadnought and personal flagship of the Dark Lord of the Sith Darth Vader. 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 Executor was destroyed after a wayward Rebel A-wing starfighter piloted by Arvel Crynyd crashed into its bridge, causing the Super Star Destroyer to lose power and collide with the DS-2 Death Star.
