The '''''Marathon''-class heavy cruiser''' ([[hull classification symbol]]: '''CA'''){{Ref/Reuse|h2a}} is a classification of [[cruiser]] in service with the [[UNSC Navy]]. Built as a replacement for the {{Class|Halcyon|light cruiser}}, the ''Marathon''-class is nearly 1.2 kilometers long, heavily armored, and equipped with two [[Magnetic Accelerator Cannons]] and an impressive arsenal of missiles.{{Ref/Reuse|ENC}}

These vessels were most often deployed in attack and defense roles, serving as the backbone of UNSC fleets, though they were also popular among high-ranking [[UNSC]] officers for use as [[Flagship|command ships]],{{Ref/Reuse|EVG}} and were even deployed in rare instances in a [[Carrier|light carrier]] configuration.<ref name="fb125">'''[[Halo: Fleet Battles]]''', ''Core Rulebook - page 125''</ref> They were primarily used during the [[Human-Covenant War]], though their numbers were heavily diminished and only very few remain in service in the conflict's aftermath alongside their successor vessel, the [[Autumn-class heavy cruiser|''Autumn''-class heavy cruiser]].<ref name="H4VG">'''[[Halo 4: The Essential Visual Guide]]''', ''UNSC Cruiser, page 191''</ref> However they continue to serve in the UNSC fleet with effectiveness and distinction 

==Design details==
===Superstructure and hull===
[[File:HFB-UNSCLeviathan.png|thumb|250px|left|The {{UNSCShip|Leviathan}}, [[Vice Admiral]] [[Michael Stanforth]]'s [[flagship]].]]
At {{Convert|1192|m|ft|sp=us}} long,{{Ref/Reuse|EVG}} ''Marathon''-class heavy [[cruiser]]s are more than twice the length of a typical [[UNSC frigate|frigate]]. Despite their size, ''Marathon''-class cruisers are dwarfed by most [[Covenant cruiser]] classes.{{Ref/Reuse|ENC}} As the successor to the ''Halcyon''-class cruiser, these vessels have a similar profile, with a forward 'head' and large engine segment protected by armor cowlings, yet are not not identical and feature a streamlined inwards-slanted underside. The class also sports a thick 191-centimeter hull of [[Titanium-A armor]], enabling it to withstand substantial amounts of fire even from [[plasma]] weaponry.{{Ref/Reuse|ENC}} By [[2552]] the ''Marathon'' was considered to be one of the more powerful [[warship]]s ever built by [[human]]ity,<ref name="for188">'''Halo: The Fall of Reach''', ''page 188'' (2010)</ref> outclassing its predecessor in virtually every respect.{{Ref/Reuse|ENC}}

Like all warships of the UNSC Navy, ''Marathon''-class heavy cruisers have a degree of operational flexibility that is achieved through the use of modular mission packages and reconfigurable [[hangar bay]]s. Though a rare configuration, these cruisers could be modified and equipped to function as a [[Carrier|light carrier]], sacrificing [[missile]] pods and all of its cargo bays for additional hangar capacity.{{Ref/Reuse|fb125}}

===Crew and complement===
''Marathon''-class heavy cruisers feature a standard complement of one thousand personnel, and are typically commanded by a [[captain]] or [[Admiral|rear admiral]], often being reserved for [[admiral]]s to use as [[Flagship|command ships]] due to their characteristic durability and firepower.{{Ref/Reuse|ENC}} They are also known to have the capacity to carry [[UNSC Marine Corps|Marine]] contingents as well as accompanying [[dropship]] transportation.{{Ref/Reuse|TFoR23}}

Cruisers of the ''Marathon'' class are fitted with at least two hangar bays.<ref name="Genesis">'''[[Halo Wars: Genesis]]'''</ref><ref name="fb">'''Halo: Fleet Battles''', ''Stats''</ref> A large deployment bay containing numerous [[Single Occupant Exoatmospheric Insertion Vehicle]]s, referred to by [[Orbital Drop Shock Troopers]] as "Hell's waiting room", is located amidships.{{Ref/Reuse|ODST}} Space aboard a ''Marathon'' is optimized to maximize the amount of heavy weapons and armor equipped on each ship, preventing the cruisers from carrying more [[space fighter]]s; despite this, ''Marathon''-class heavy cruisers can carry two dozen [[GA-TL1 Longsword]]s.{{Ref/Reuse|ENC}}{{Ref/Note|As this is a very large number of fighters, and it has been stated that UNSC cruisers specifically trade fighter-carrying capacity for armaments and armor, it is likely that this number represents the carrying capacity of the ''Marathon''-class when in its converted light carrier configuration instead of in its standard form.}}

===Armaments===
''Marathon''-class heavy cruisers are mounted with two [[Magnetic Accelerator Cannon]]s as their primary armament,{{Ref/Reuse|universe}}{{Ref/Reuse|EVG}} supplemented by a missile delivery system{{Ref/Reuse|universe}} with 1,800 [[Archer missile]]s and five [[fusion rocket]]s.{{Ref/Reuse|ENC}} In addition, the ''Marathon''-class utilises a network of [[point-defense gun]]s.{{Ref/Reuse|universe}}

==Service history==
[[File:HWG SecondBattleOfHarvest.png|thumb|250px|Several ''Marathon''-class heavy cruisers engaging the {{Pattern|Rasus|interdictor}} at Harvest.]]
The ''Marathon''-class heavy cruiser was commissioned and built as a replacement for the {{Class|Halcyon|light cruiser}},{{Ref/Reuse|ENC}} a smaller and more lightly armed cruiser which suffered from excessive production costs and a lack of tactical viability.{{Ref/Reuse|EVG}} After a brief era of service,{{Ref/Reuse|universe}} most ships of the ''Halcyon''-class were decommissioned, which led to the ''Marathon''-class rising to prominence. By [[2525]], the ''Marathon''-class was the most popular line of [[cruiser]] in service with the Navy.{{Ref/Reuse|EVG}}
===Human-Covenant War===
{{Main|Human-Covenant War}}
Several ''Marathon''-class heavy cruisers served in [[Battle Group X-Ray]] under [[Preston Cole|Vice Admiral Preston Cole]] during the [[Battle of Harvest]]. Throughout the early years of the [[Human-Covenant War]], ''Marathon''s continued to serve in Cole's [[Third Fleet]]. Several ''Marathon''s from the fleet, including {{UNSCShip|Prophecy}}, participated in the [[Harvest campaign]].{{Ref/Reuse|Genesis}}<ref name="Timeline">'''[[Halo Wars]]''', ''[[Halo Wars Timeline Events|Timeline]]''</ref> At least one ''Marathon''-class heavy cruiser, {{UNSCShip|Dresden}}, participated in the [[Battle of Biko|Battle]] of [[Biko]], where it was destroyed by the [[Covenant]].{{Ref/Reuse|tug}}

[[File:Fifth Fleet - H2A.png|thumb|250px|left|Numerous ''Marathon''s hold position over Earth.]]
As their numbers were diminished by the onslaught of the Covenant, many ''Marathon''s were reassigned to the defense of the [[Inner Colonies]] and [[Earth]] during the later years of the Human-Covenant War.<ref name="page162">'''Halo: The Fall of Reach''', ''page 162''</ref> As of [[2552#July|July 2552]], only 20 cruisers remained within the UNSC fleet, possibly at least among the [[FLEETCOM Sector One]].{{Ref/Note|See [[UNSC Leviathan#Notes|here]] by regarding the number of remaining cruisers as of July 2552}} [[Vice Admiral]] [[Michael Stanforth]]'s [[flagship]] [[UNSC Leviathan|''Leviathan'']] of the [[Battle Group Leviathan]] was present at the [[Battle of Sigma Octanus IV]] in [[2552#July|July 2552]] and was severely damaged during the battle.{{Ref/Reuse|for188}}<ref>'''Halo: The Fall of Reach''', ''page 224'' (2010)</ref> Numerous ''Marathon''-class heavy cruisers participated in the [[Fall of Reach]], many of which were destroyed, including ''Leviathan''.{{Ref/Reuse|ENC}}{{Ref/Reuse|fb}}<ref name="fs206">'''Halo: First Strike''', ''page 168'' (2003), ''page 206'' (2010)</ref>

At least eight ''Marathon''-class cruisers (including {{UNSCShip|Canberra}}{{Ref/Reuse|h2a}} and [[UNSC Say My Name|''Say My Name'']],<ref name="waypoint">[http://halo.xbox.com/en-us/intel/related/gallery/unsc-say-my-name/87da73b5-cede-44fd-906e-c3d1f57abf44 '''Halo Waypoint''': ''UNSC Say My Name''] (defunct, backup on [https://web.archive.org/web/20110424040357/http://halo.xbox.com/en-us/intel/related/gallery/unsc-say-my-name/87da73b5-cede-44fd-906e-c3d1f57abf44 Archive.org])</ref> assigned to the [[Fifth Fleet]], a part of the [[UNSC Home Fleet]]) were present at the onset of the [[Battle for Earth]]. Led by [[Joseph Harper|Fleet Admiral Joseph Harper]] aboard ''Canberra'' and supported by sixty-seven {{Class|Stalwart|light frigate}}s, these ships formed a defensive perimeter around the [[orbital defense platform]] cluster over the Mediterranean to prevent the [[Fleet of Sacred Consecration]] from reaching Earth's surface.<ref>'''Halo 2''', campaign level ''[[Cairo Station]]''</ref> [[Carl Patterson|Admiral Carl Patterson]]'s [[Battle Group Omicron]], drawn from the Home Fleet, contained one ''Marathon''-class heavy cruiser that participated in the [[Onyx Conflict]], where she was destroyed with the rest of her [[battle group]].<ref>'''Halo: Ghosts of Onyx''', ''pages 292, 333''</ref> Several ''Marathon''-class cruisers of the Home Fleet were presumably destroyed over the course of the Battle for Earth, particularly after the final wave of Covenant reinforcements arrived.<ref>'''[[Halo 3]]''', campaign level ''[[Crow's Nest]]''</ref>

===Post-war===
Most remaining ''Marathon''-class heavy cruisers were decommissioned after the {{Class|Autumn|heavy cruiser}} was introduced, with only a handful staying in service.{{Ref/Reuse|H4VG}} The ''Autumn'' class became slated to serve as the core of the reconstituted UNSC Navy's fleet, a role the ''Marathon'' class had previously fulfilled.{{Ref/Reuse|universe}} A ''Marathon''-class heavy cruiser served as the flagship of Admiral [[Graselyn Tuwa]] during [[Operation: JOVIAN WHISTLE|an operation]] on [[Gao]] in [[2553]]. The presence of the cruiser prevented [[Arlo Casille|Minister of Protection Arlo Casille]] from taking naval action against the UNSC, realizing that the cruiser could easily decimate his entire fleet of [[patrol corvette]]s.<ref>'''[[Halo: Last Light]]''', ''page 71''</ref>

==Non-canon and dubious canon appearances==
===''Halo: Fall of Reach - Boot Camp''===
Several ''Marathon''-class heavy cruisers participated in the [[Operation: TREBUCHET]] over [[Eridanus II]] against the [[Insurrectionist]]s in [[2513]] during the [[Insurrection]].{{Ref/Comic|Id=hfor|Comic=Halo: Fall of Reach|Story=[[Halo: Fall of Reach - Boot Camp|Boot Camp]]|Issue=[[Halo: Fall of Reach - Boot Camp#Issue 1|#1]]}}{{Ref/NoteReuse|service}} One of these cruisers threatened the [[United Rebel Front|URF]] [[Human starship|vessel]] ''[[Gateway (ship)|Gateway]]'', which experienced difficulties with its [[Shaw-Fujikawa Translight Engine|slipspace drive]], until it was later ripped apart by [[Robert Watts]] using towing cables on his {{Class|Charon|light frigate}}, ''[[Iliad]]'',  and he sent the cruiser's debris into a collision course with another UNSC vessel, destroying both ships, alongside a ''Halcyon''-class cruiser.{{Ref/Reuse|hfor}}

==Trivia==
{{Linkbox|gallery=yes|gallerypage=Images of Marathon-class heavy cruisers}}
*Though in-universe the class is likely named for the [[Wikipedia:Battle of Marathon|Battle of Marathon]], in reality its name is a reference to [[Bungie]]'s ''[[Marathon]]'' trilogy and its eponymous ship, the [[marathongame:UESC Marathon|UESC ''Marathon'']].
*The ''Marathon'' class is featured in ''[[Halo: Fleet Battles]]''; although the {{Class|Halcyon|light cruiser}} was originally intended to appear instead, it was decided that the latter's appearance would not be canonically possible. The design for the ''Marathon'' class in the game was noted to have been difficult to sculpt, although the models created by [[Blur Studio]] for ''[[Halo 2: Anniversary]]'' aided in the process.<ref>[https://www.halowaypoint.com/en-us/news/canon-fodder-in-the-loop '''Halo Waypoint''': ''Canon Fodder: In the Loop'']</ref>
