The Annihilator was commanded by Admiral Gaarn shortly after the Battle of Endor. The combined forces of the Zann Consortium were eventually able to destroy the Annihilator and the remaining Imperial ships, allowing Zann to safely access the Eclipse 's data archives.

However, the Super Star Destroyer focused its assault on its primary target, the Eclipse, and attempted to destroy the massive warship before it fell into enemy hands. The Annihilator began assaulting the forces of the Zann Consortium with turbolaser and ion cannon barrages, and launched starfighter squadrons from its hangar. The Annihilator and its fleet dropped out of hyperspace above Kuat shortly after the Eclipse 's superlaser, recently hijacked by Zann's forces, malfunctioned. The Annihilator, under the command of Admiral Gaarn, led a small fleet of three Imperial-class Star Destroyers to assist the already thinning group Imperial forces spread out above the planet. Shortly after the Battle of Endor, the crime lord Tyber Zann launched an attack on the Imperial shipyards at Kuat in an attempt to capture the half-constructed warship Eclipse. The ship was propelled by thirteen engine units and was protected from enemy fire by deflector shields emitted from two generator domes placed along the ship's command tower. It housed numerous squadrons of TIE Series starfighters, including fighters, bombers, interceptors, and Defenders. The warship was also armed with several concussion missile and proton torpedo launchers. The Super Star Destroyer boasted many turbolaser, ion cannon emplacements and tractor beam projectors. The Annihilator was a 19- kilometer-long Executor-class Star Dreadnought in the service of the Galactic Empire.
