Marathon-class heavy cruiser

Marathon-class Cruiser The Marathon-class Cruiser is a classification of United Nations Space Command warship.

Description
These starships were the replacement for the aging. These behemoths, ranking in at 1192 meters, are over two times the length of a UNSC Frigate. They are also known for their heavy armor - they can survive multiple plasma torpedo impacts, far greater damage than any UNSC Frigate or UNSC Destroyer can sustain.

Appearances
Due to their diminishing numbers and the onslaught of the genocidal Covenant, further numbers of these great cruisers have been reassigned to the defense of the Inner Colonies. Marathons were seen at the Battle of Sigma Octanus IV, the Battle of Reach, the First Battle of Earth, and the Battle of Onyx. Eight or more Marathons battled in the First Battle of Earth under the command of Fleet Admiral Harper. Yet another was within Battle Group Stalingrad in the Battle of Onyx. It is very likely if not certainly due to their sheer power that these cruisers also participated in the Second Battle of Earth.

 * The name Marathon comes from Bungies Pre-Halo Marathon series of games.
 * They bear a resemblance to the older Halcyon-class cruisers.
