Sh'wada-pattern supercarrier

The CSO-class supercarrier is a powerful Covenant capital warship, primarily designed for command and control duties for fleets, as well as support for occupation forces. Such vessels are typically deployed only during invasions of worlds with high strategic value. It is the largest known ship seen in the Human-Covenant War.

Design
The supercarrier is an extremely large and well-equipped capital ship, easily dwarfing most other Covenant starship classes. The vessel looks nearly identical to the, sharing the smaller ship's design of several bulbous sections and a hook-like prow, albeit painted purple instead of white.

Classification

The "O", or Ordained, indicates that the CSO-class supercarrier is not a mission type and has been improved upon with Forerunner technology.

Operational history
During the Fall of Reach the supercarrier Long Night of Solace spearheaded the Covenant invasion of Reach as the flagship of the Fleet of Valiant Prudence, deploying numerous ground assets to the surface of Reach via teleportation spires and destroying the.

During Operation: UPPER CUT, Spartan Jorge-052 transported an improvised slipspace bomb toward Long Night of Solace aboard the corvette Ardent Prayer while SPARTAN-B312 locked course with the supercarrier. After SPARTAN-B312 was jettisoned from the hangar, Jorge manually detonated the bomb, destroying both the corvette and the supercarrier at the cost of his own life.

Sublime Transcendence served as the flagship of the Combined Fleet of Righteous Purpose. It was destroyed when one of the Unggoy on board, Kwassass, inadvertently triggered a voice cue in a databox, thereby arming a NOVA Bomb they recovered from Reach: after playing a message by Admiral Whitcomb, the detonation was caused by a group of Huragok, who reinserted the databox inside the bomb itself, despite Kwassass's efforts to prevent them from doing so after realizing the threat.
