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. The Spirit of Fire, as speculated by the Halo Wars trailer, carries vehicles and troops. It alos carries the resources neccessary to build bases. 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.
