Crassus-class supercarrier

The aircraft carrier is a seaborne warship in service with the United Nations Space Command, presumably by the Navy. Such a vessel is capable of carrying multiple D77-TC Pelicans and F-99 Unmanned Combat Aerial Vehicles.

At least two such aircraft carriers took part during the Battle of Mombasa on October 20, 2552. These vessels deployed F99 UCAVs to provide surveillance and air strikes against the Covenant, supporting scattered UNSC Marines and New Mombasa Police Department personnel. Their ultimate fate following the glassing of the city is unknown.
