Courage was a Thranta-class War Cruiser and the sister ship of Valiant and Fidelity. Manned by droid crews, the three ships served as the escort of the Alderaanian War Frigate Another Chance, which was carrying all of Alderaan's leftover weapons after that world disarmed in the wake of the Clone Wars. When the Another Chance was located by Rebel sympathizers and its weapons given to the struggling Alliance in the wake of the Battle of Derra IV, Courage was left to wander the Alderaan system. It is assumed that the ship continued its vigil for many years afterward.
