UNSC Leviathan was a Marathon-class heavy cruiser in service with the UNSC Navy and commanded by Vice Admiral Michael Stanforth.

Operational HistoryEdit

It was a veteran vessel, having seen numerous engagements, including the Battle of Sigma Octanus IV, where it took a Plasma Torpedo to its bow starting fires in its foredecks.[1] After the Battle at Sigma Octanus, Leviathan returned to Reach. It was destroyed during the Fall of Reach, with Admiral Stanforth among the crew that perished in the battle.


  • The ship may have been named after the Leviathan, a gigantic sea beast of Hebrew legend.
