The Glamorgan was sent by the Office of Naval Intelligence to investigate the remains of Onyx at Zeta Doradus. It picked up a transponder signal from SPARTAN Kurt-051's armor, confirming that he was killed in action. Admiral Margaret Parangosky's artificial intelligence, Black-Box, left a fragment of himself on the ship in case anything else was found.
