The Ruma-pattern light carrier[3] (UNSC three-letter classification: DDS-class carrier)[1], is a heavy warship within the now-defunct Covenant fleet that served as a force deployment and occupation warship.[1]

Design details[edit]

Superstructure and hull[edit]

The DDS-class carrier, unlike the larger and more powerful CAS-class assault carrier, is a less frequently encountered, but powerful, warship within the Covenant fleet. The primary role of the DDS-class carrier is to support fleet actions in space, or as an infantry deployment platform. The DDS-class carrier has three bulbous sections; its swollen center boasts a total of thirteen launch bays on both sides of the ship.[6] It is used for command and control of large numbers of deployment waves of space fighters, dropships, and interceptors.[1] Like all warships, these ships come in a variety of classes and sizes, though military observers note there are variance of weaponry, length, and estimated tonnage.[7]

The carrier's hull is reinforced with over thirty meters of nanolaminate hull plating and equipped with energy shielding.[8] A single plasma torpedo is capable of causing several layers of the hull to boil away. The shieldless hull of a DDS-class carrier is capable of withstanding heat of up to three hundred degrees Celsius, with no actual damage done to the carrier's structure.[9] Only at extreme temperatures of over seventeen hundred degrees Celsius does minor hull tearing and conduit melting occur.[10] However, at such high temperatures, the superstructure of the vessel becomes considerably softened.[11]

Complement and crew[edit]

The DDS-class carrier boasts three hundred Type-31 Seraph starfighters,[2] divided into three different squadrons,[12] two hundred Type-26 Banshees, and thirty-four dropships—either Dextro Xur-pattern Spirits or Ru'swum-pattern Phantoms—that can be launched at any given moment from the thirteen launch bays located along the center sides of the ship.[2][13]

The DDS-class carrier holds a crew of three to four thousand Covenant infantry,[13] most of which were Huragok in the case of Ascendant Justice, with a light company of Unggoy and only a hundred Sangheili.[14] The crew was available for deployment on a moments notice via the ship's gravity lift when close to a world's surface.


Like other ships within the Covenant fleet, the DDS-class carrier boasts a vast array of energy weapons. The DDS-class carrier is armed with seven plasma torpedo launchers, numerous pulse laser turrets, and anterior plasma cannons.[13][1] The "S", or Salvation, in the carrier's three-letter classification code, "DDS", indicates that the DDS-class carrier is a dedicated warship.[15]

Service history[edit]

DDS-class carriers participated in the invasion of Reach and subsequent destruction of the planet.[citation needed] At least one, Ascendant Justice, was assigned to the Fleet of Particular Justice and pursued UNSC Pillar of Autumn to Installation 04 after the battle.[16][15] Following the Battle of Installation 04, Ascendant Justice was captured by UNSC forces and captained by Vice Admiral Danforth Whitcomb,[17] until its destruction during Operation: FIRST STRIKE.[18]
