Sanctity of Purification
From Halopedia, the Halo wiki
In April 2552, the Sanctity of Purification was part of a Covenant invasion force sent to attack the colony of Fumirole. During the resulting Battle of Fumirole, the Sanctity would hold position over a city on the planet during a pitched battle between UNSC Army forces and the Sanctity's troop complement, using its gravity lift to move troops and supplies onto the planetary surface.
To assist in defending the planet, NOBLE Team were deployed to the ground under a plan devised by Kat-B320 to deliver a Fury tactical nuclear weapon into the heart of the cruiser. The team would be succesful in pushing on the cruiser, though a well-placed fuel rod air strike by a Type-26 Banshee would ultimately hit Kat, rendering her unable to complete the mission. Due to this, Spartan Thom-A293 would take the nuke with only a small amount of time left until detonation, and proceed to use his Series 8 jetpack to fly into the gravity lift and enter the hangar bay of the battlecruiser and throw the nuke into the middle of the Covenant deployment.
Ultimately, the Sanctity of Purification would be consumed in the detonation of the nuke, destroying the battlecruiser and Thom in the process. The explosion would be visible from orbit.
