The Eclipse-class dreadnought, also known as the Eclipse-class Super Star Destroyer, was a class of Imperial Super Star Destroyer manufactured by Kuat Drive Yards and mainly used around six years after the Battle of Endor. Like the Sovereign-class, they were regarded as a new generation of Super Star Destroyer.
The Eclipse-class vessels were among the largest dreadnought-scale ships/Super Star Destroyers ever to be fielded within Galactic history. Although technically dwarfed in length by both the Executor-class Star Dreadnought and the Vengeance-class dreadnought by 1.5 kilometers, the Eclipse-class nonetheless exceeded even the Executor-class in terms of overall mass and volume. Its size was large enough for it to be classified as a space station.
