UNSC Commonwealth

The Commonwealth (FF-225) was a Paris-class frigate of the UNSC Navy. In 2525, its commanding officer was Captain Phillip Wallace.
== History ==
In 2525, the Commonwealth ferried the Spartan-IIs along with Lieutenant Catherine Halsey to the Damascus Testing Facility on the planet Chi Ceti IV. There, during the Battle of Chi Ceti, the Commonwealth successfully engaged the Imperial frigate Liberator. During the engagement, the Commonwealth was able to fight off the Imperial ship long enough to perform a flyby orbit of Chi Ceti IV to deploy its crew onto the planet, intending to then return to a point in space twenty million kilometres from the planet to make repairs and act as bait in the event that the vessel returned. While the crew were on the ground, Commonwealth continued to engage the ship, sustaining heavy damage.
Ultimately, with the assistance of the Spartan-IIs' boarding party, and their new MJOLNIR Mark IV armor, the Commonwealth was able to destroy the frigate. The Commonwealth, however, was severely damaged in their first engagement against the Empire and shortly thereafter rendezvoused with the UNSC Persian Gate to transfer the Spartans and Lt. Halsey to the ship.
Despite the damage incurred, the Commonwealth was able to return to Reach for repairs and subsequently returned to service against the Empire's advances among the Outer Colonies. Sometime prior to the Fall of Reach, the ship sustained irreparable damage, being finally decommissioned and sent to the Sinoviet HM shipbreaking yards in Aszod for disassembly.
