Human-Covenant War[2]




The CSO-class supercarrier is a powerful Covenant supercarrier 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.[3]



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 Kerel-pattern CAS-class assault carrier, sharing the smaller ship's design of several bulbous sections and a hook-like prow, albeit painted darker.[2]


The "S", or Salvation, in the supercarrier's three-letter classification code, "CSO" indicates that the carrier is a dedicated warship. The "O", or Ordained, indicates that the CSO-class supercarrier is not a mission type and has been improved upon with Forerunner technology.[4]

Along with the CAS, the CSO is designated a Class-Five flagship carrier by the UNSC due to their use as a flagship of Covenant fleets.[3]

Operational history[edit]

Fall of Reach[edit]

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 UNSC Grafton.[5]

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.[6]
