A Phoenix-class Colony Ship, The Spirit of Fire
The Phoenix-class starship are often modified into warships, such as the UNSC Spirit of Fire, which is a modified Phoenix converted for Wartime-use. It will be the main ship in Halo Wars. The name Phoenix is likely a nod to Bungie's canceled game of the same name.
