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 II Mobile Battle Station.

One of the largest and most powerful Imperialvessels ever created, the Executor was 19,000 meters long, eclipsing its escorting Imperial-class Star Destroyers, and boasted more than 5,000 turbolasers and ion cannons. The center of her arrowhead-shaped hull was covered by a city-like superstructure, while the underside hosted most of the engineering systems. The aft end of the Executor was marked by a trapezoid command tower crowned by two geodesic communication and deflection domes; at the bottom end of the hull were thirteen thrusters responsible for moving the vessel.

As in the Imperial I– and Imperial II-classes, the bridge of the Executor featured two elongated pits set below floor level, and a walkway where the superior officers stood. One notable difference was that, around 3 ABY, the pit consoles were aligned parallel to the walkway, instead of perpendicular. However, by 4 ABY, the arrangement of the consoles had been altered to match that of smaller Destroyers.
