Super - class Star Destroyer The " Super " - class Star Destroyer was a fictional Star Destroyer model invented for budgetary reasons , whose name later became a popular military colloquialism for heavy warships of the Galactic Empire and successor - governments . Characteristics . The " Super " - class was described as 8 , 000 meters long , armed with 250 turbolaser batteries , 250 heavy turbolaser batteries , 250 ion cannons , 250 concussion missile tubes , and 40 tractor beam projectors . It would carry twelve TIE squadrons ( including two TIE Interceptor squadrons ) and more than fifty other small craft . For ground operations , it would carry a full corps of ground troops , apparently mixing stormtrooper legions with regular Army personnel , plus 25 AT - ATs , 50 AT - STs , and three prefabricated garrison bases . It would have been crewed by 280 , 734 . A single ship of this class would be considered the equal of ten or twenty " Imperial " - class Star Destroyers , and they were meant to be used as command ships by many of the most important Sector Fleet s in the Empire . History . The name " " Super " - class Star Destroyer " was invented by Imperial Navy officials and used in its budget requests to the Imperial Senate during the design and construction phase of the " Executor " - class Star Dreadnought . This ruse was made to hide the true nature of the class , even going so far as to understate its size and armament , so that oversight committees would not discover its true role . By the time the first vessel , " Executor " , was operational , the official designation had been changed to its original intention , but Super Star Destroyer and " Super " - class Star Destroyer had stuck in people ' s minds and was applied to other models , like the " Sovereign " - class and " Eclipse " - class . One of these budget requests which included the " " Super " - class " and several other capital ship designs was sent to Palpatine ' s advisors on budgetary affairs . This document found its way into the hands of the Rebel Alliance , where it was used as a primary source regarding the Empire ' s capital ship capabilities by Arhul Hextrophon . The Empire publicly revealed that four " Super " - class Star Destroyers , specifically " Executor " - class vessels , were completed by the Battle of Hoth . Circa 1 BBY , Imperial gunner Tenn Graneet hoped he would be assigned to one of them . Legacy . Even into the time of the New Jedi Order , both the terms " Super Star Destroyer " and " " Super " - class Star Destroyer " were still in use , and over the decades came to refer to several distinct designs . The " Megador " , a Super Star Destroyer with sixteen ion engines , was also referred to as a " Super " - class Star Destroyer during the Battle of Uroro Station . Behind the scenes . Since 2004 , the " Executor " - class were described as Star Dreadnoughts at 19 kilometers in length . The issue had some controversy , as many older sources described the " Executor " as either an 8 - or 12 . 8 - kilometer - long " Super " - class Star Destroyer . On March 9th 2006 , the Wizards of the Coast " Star Wars " Q & A section reiterated that the " Executor " was 19 kilometers , " as are all Super Star Destroyers of the same class . " This kept the 8 - kilometer " Super " - class as a possibility , as such ships could belong to a different class from " Executor " . However , with the " Starship Battles Preview 1 " preview article on October 19 , 2006 , the " Super " - class was retcon ned as explicitly fake , being used to hide the much larger " Executor " Star Dreadnought class . On November 16 , 2007 , the official Databank updated the " Executor " article , pointing out that the term " " Super " - class Star Destroyer " was only used unofficially , alongside " Super Star Destroyer , " with " " Executor " - class Star Dreadnought " being the ship class ' s real designation . The updated edition of " Starships of the Galaxy " repeated the information , even adding more Super Star Destroyer variants to the mix and using both " Super Star Destroyer " and " " Super " - class Star Destroyer " interchangably as general descriptions .
