La Nave Insignia de Darth Vader

In a military sense, the Super Star Destroyer was somewhat impractical, since a smaller ship could fulfill its mission duties. Rather, the Super Star Destroyers represented the Emperor's unlimited power and resources. The Imperial Star Destroyer frightened worlds into submission; the Super Star Destroyer terrorized them beyond the capability for resistance. At over five times the length of a standard Star Destroyer, it could conquer without firing a shot, and so win the battle before engaging the enemy.
Bristling with over a thousand weapons, including turbolasers, concussion-missile tubes, tractor beam projectors, and ion cannons, Super Star Destroyers wielded awesome firepower. They held two full wings of TIE fighters, for 144 ships, as well as 200 other combat and support ships. For ground assaults, Super Star Destroyers maintained a full corps of stormtroopers, 38,000 ground troopers, three prefabricated Imperial garrison bases, and enough walkers to decimate any Rebel base.
The Executor was built at the starship yards of Fondor after being designed by Lira Wessex, designer of the Imperial Star Destroyer. Upon its completion, the ship was presented to Lord Vader as a headquarters ship for his quest to find the Rebel Alliance's command base. It was originally commanded by Admiral Ozzel, but after his unfortunate death, Admiral Piett was given command of the vessel by Lord Vader.
The Executor was destroyed at the Battle of Endor. After its shield generators were destroyed, Rebel fighter pilot Arvel Crynyd smashed his A-wing fighter into the Executor's bridge. With the ship crippled and damage control crews unable to sieze command using the auxiliary control centers, the Death Star's gravity pulled the Executor into the immense battle station. The Executor exploded on impact with the Death Star, also causing significant damage to the incomplete battle station. Many of the Empire's best young officers were killed in that incident, making the New Republic's eventual victory over the Empire far easier.
While only four Super Star Destroyers were in service by the Battle of Hoth, it is known that several more were under construction. It is unknown how many of these ships were completed before the Battle of Endor, but several are thought to be in the hands of rogue Imperial warlords.
The first of four Super-class Star Destroyers in service before the Battle of Hoth, the Executor was Darth Vader's command ship while he hunted down the main Rebel Alliance base. At 8,000 meters long, it was the largest traditional starship constructed by the Imperial Navy - only the Death Stars and torpedo spheres were larger. Super Star Destroyers were Imperial Navy command ships and were assigned only to the most important and prestigious missions. Being assigned to the Executor was regarded by Navy officers as the fast track to promotion.
