UNSC Redoubtable
From Halopedia, the Halo wiki
The UNSC Redoubtable was a UNSC frigate. In 2552, it was stationed at Earth during The First Battle of Earth. The Paris descended near New Mombasa to help in the fight taking place there, and was one of four ships fast enough to follow the UNSC In Amber Clad into slipspace with the Assault Carrier commanded by the High Prophet of Regret. The Redoubtable was faster than the Dusk, and sped out of their sensor range in slipspace. The ultimate fate of the Redoubtable, UNSC Paris, and Coral Sea is unknown.
