Executor-class Star Dreadnought

Executor-class Star Dreadnoughts, also known as Super-class Star Destroyers or simply Super Star Destroyers, were some of the largest and most powerful Imperial starships ever created. Along with other classes of massive Imperial capital ships, they were also referred to as Super Star Destroyers, although they were technically classified as Star Dreadnoughts. The most distinguished Super Star Destroyer was the Executor, flagship of the Dark Lord of the Sith, Darth Vader.
