UNSC Commonwealth

The UNSC Commonwealth was a United Nations Space Command Frigate commanded by Captain Wallace. In 2525, the Commonwealth ferried the Spartan II's and Dr. Catherine Halsey to the Damascus Testing Facility on the 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 Spartan II's and their new MJOLNIR Mark IV Armor, was able to destroy it. The Commonwealth, however, was severely damaged in the battle.
