The ship was refitted with three Magnetic Accelerator Cannons and other armaments to serve as a warship. Directly after Alexander's retirement, the vessel was requisitioned by the UNSC and scheduled for refit in order to better prepare it for the combat operations in which it would participate. The last civilian Captain of the Spirit of Fire was a man named Alexander, who had retired from active duty on July 20, 2520, after visiting the world of Verent. Īlmost fifty years after being constructed, it was recommissioned and refitted for military service prior to the period of history known as the Human-Covenant War. During this period, the Spirit of Fire was directly involved in setting up infrastructure on the nascent colonies of Arcadia and Verent. The Spirit of Fire was originally a colony ship, transporting colonists as well as equipment such as hydroponics, atmosphere generators, and prefabricated schools, in the UNSC's expansion efforts. While Serina perished during the journey as per her limited lifespan as a smart AI, the Spirit of Fire gained a new shipboard AI in Isabel, the only survivor of the Banished's attack on the UNSC outposts on the Ark. After 28 years of drifting through space, the Spirit of Fire was mysteriously transported through a slipspace portal to the Ark where the crew was forced into a conflict with the occupying Banished. After the crew sacrificed her slipspace drive to destroy the Forerunner shield world known as Trove, the Spirit of Fire was forced into a slow return trip back to human space at sub-luminal velocities and was officially declared "lost with all hands" in 2534. In 2531, her commanding officer was Captain James Cutter and her primary shipboard AI was Serina. Built in 2473, the Spirit of Fire is a heavily modified colony ship. UNSC Spirit of Fire ( hull classification symbol CFV-88) is a Phoenix-class support vessel in service with the UNSC Navy.
