The first of the ships, the Sovereign, was still under construction at the shipyards of Byss by the time of Operation Shadow Hand. Other planned ships in the class included the Autarch, Despot, and Heresiarch.
A Super Star Destroyer variant measuring fifteen thousand meters long, the Sovereign-class was classified as a dreadnaught under the Anaxes War College system. The Sovereign-class hosted a crew of 601,670, with 4,075 gunners, and required a skeleton crew of at least 86,000. It could carry up to 400,000 metric tons of cargo and hosted a complement of 35 TIE/IN interceptor squadrons, five TIE/sa bomber squadrons, and 75 All Terrain Armored Transports.
A Sovereign-class Super Star Destroyer carried five years' worth of consumables and could carry 130,100 troops. Like the larger Eclipse-class dreadnought, the Sovereign-class featured an axial superlaser on par with the Death Star. It also hosted five hundred heavy laser cannons—200 to the front and 150 to the left and right—which each required two gunners, and five hundred turbolaser batteries—150 front, 100 to the rear, and 125 each on the left and right.
In addition, the Sovereign-class possessed seventy-five ion cannons split equally between the front and sides, and 100 tractor beam emplacements, wth 55 to the front, 5 to the rear, and 20 each to the left and right. Five gravity well projectors rounded out the vessel's armament.
