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 starship known to date is the UNSC Spirit of Fire , which is a modified Pheonix converted for Wartime-use. It will be the main ship in Halo Wars. The name Pheonix is likely a nod to Bungie's cancelled game of the same name. Template:UNSC Ships
