The Eclipse-class vessels were among the largest dreadnought-scale ships/Super Star Destroyers ever to be fielded within Galactic history. Although technically being dwarfed in length only by both the Executor-class Star Dreadnought and the Vengeance-class dreadnought by 1.5 kilometers, the Eclipse-class nonetheless outranked even the Executor-class in terms of overall mass and volume. Its size in addition was also large enough for it to also be classified as a space station.
