The most deadly weapon carried by Eclipse-class ships was an axial superlaser, similar to but significantly less powerful than one of the component beams used in the Death Star's superlaser. Its size in addition was also large enough for it to also be classified as a space station.
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. The Eclipse-class vessels were among the largest dreadnought-scale ships/Super Star Destroyers ever to be fielded within Galactic history.
