Marathon-class heavy cruiser

Marathon-class Cruiser The Marathon-class Cruiser is one of the most powerful warship in the UNSC fleet. They were the replacement for the aging Halycon-class Cruiser. However, due to their diminishing numbers, further numbers of these great vessels have been retrograded to the Inner Colonies. Now, there are only 20 or so such monsters in the UNSC fleet (though there is evidance to say there are many more because if you watch throught he windows on the cairo station you can see more than 23 at some points so there must be large numbers of them)

These behemoths, clocking in at 1192 meters, approximately two and a half times the length of a UNSC Frigate, sport at least three Magnetic Accelerator Cannons (according to an outline of the Marathon classification), probably amongst other armaments. They are also known for their heavy armor - they can survive multiple plasma torpedo impacts, far greater damage than any UNSC Frigate, UNSC Halycon class cruisers or UNSC Destroyer can sustain.

Marathon-class cruisers were seen at the Battle of Sigma Octanus IV, the Battle of Reach, the First Battle of Earth. Eight or more Marathon-class cruisers battled in the First Battle of Earth under the command of Fleet Admiral Harper. It is very likely that these cruisers also participated in the Second Battle of Earth.
