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.[1]

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.[1]

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 Fleets in the Empire.
