UNSC Commonwealth

The UNSC Commonwealth was a United Nations Space Command Frigate commanded by Captain Wallace. In 2525, the Commonwealth ferried the Spartans and Dr. Catherine Halsey to the Damascus Testing Facility on planet Chi Ceti IV. There, during the Battle of Chi Ceti, the Commonwealth successfully engaged (what is thought to be) a Covenant frigate and, with the assistance of the Spartans and their new MJOLNIR Mark IV Armor, destroyed it. The Commonwealth, however, was severely damaged.
