UNSC Musashi
From Halopedia, the Halo wiki
The UNSC Musashi was a UNSC Carrier. In August 2552, the Musashi was at Reach. When 314 Covenant ships attacked the system, the Muashi was involved in the ensuing Battle. The Musashi fell victim to a Covenant Assault Carrier, as it moved to cover the orbital MAC platforms. The Musashi was hit with a needle thin beam of Covenant plasma which severed the vessel midship. The aft section of the ship, engines still intact, continued to thrust forward and probably crashed into the fore section of the ship, causing the carrier to completely burn up in orbit.
