Star Destroyer
According to in-universe "Star Wars" sources, the "Executor" was the lead ship of a new class of Star Dreadnoughts; the term "Super Star Destroyer" is a colloquialism applied to any ship larger than a standard Imperial Star Destroyer. At long, the ship bristles with thousands of turbolasers, ion cannons, missile launchers and tractor beams. It similarly carries more than a thousand ships including TIE Fighters.
