The Unkown transport craft is a Nova space marine ship. Their main purpose appears to be a troop transport, however it is also seen engaging a Volterite transport craft in Homecoming, meaning that it can also serve as an fighter ship.

N.O.V.A. 3Edit

The Unkown transport craft first appears in  Homecoming where it fights a Volterite transport craft. It later appears in Ice and Fire where it takes Kal Wardin to the Volterite Home world. 


A crashed transport craft appears in the map Lost World however it just serves as scenery and cannot be driven.
