Phoenix-class colony ship
From Halopedia, the Halo wiki
The Phoenix-class Colony Ship is a ship classification within the United Nations Space Command.
The only Phoenix-class starships known to date are the UNSC Spirit of Fire, which is a modified Phoenix converted for Wartime-use and the UNSC Skidbladnir. It will be the main ship in Halo Wars. The name Phoenix is likely a nod to Bungie's cancelled game of the same name. Template:UNSC Ships
