The '''Mark 2488 Magnetic Accelerator Cannon''', formally designated ''' | The '''Mark 2488 Magnetic Accelerator Cannon''', formally designated '''15cm Mark/2488 1.1GJ MAC''', also known as the '''Onager''' and often referred to as a "'''[[mass driver]]'''", is a stationary [[Magnetic Accelerator Cannon]] used by the [[United Nations Space Command]] during the [[Human-Covenant War]].<ref name="stats">'''[[Bungie.net]]''' ''Halo: Reach'' game stats</ref> | ||
The | ==Design details== | ||
The Onager is capable of firing a 15 cm round with up to 1.1 gigajoules of kinetic energy.<ref name="stats"/> It has five linearly arranged magnetic coils, each of which needs to charge individually before each shot. The weapon needs to cool off after every shot, and does so by opening a radial vent on the upper portion of the barrel. The weapon is operated from a small booth on the left side of the cannon.<ref name="reach"/> | |||

The | ===Mark 2551=== | ||
The Mark 2551/25cm Portable uses a 25cm M6792 HV/FTHPP-AS round and developed by [[Misriah Armory]]. The {{UNSCShip|Infinity}} had a hull-mounted Onager in support of its larger shipboard MACs. The [[Ivanoff Station]] made use of several automated Onagers to protect it from space debris and later against several [[CRS-class light cruiser]]s when the station was [[Raid on Ivanoff Station|attacked]].<ref>'''[[Halo 4: The Essential Visual Guide]]''', ''page 75''</ref> | |||

[[Emile-A239]] manned the mass driver to fend off incoming Covenant [[Type-26 Ground Support Aircraft|Banshees]] and [[Type-52 Troop Carrier|Phantoms]] before the ''Autumn'' could take off.<ref name="reach">'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref> However, the SPARTAN was killed by a [[Sangheili Zealot]], prompting [[SPARTAN-B312]] to commandeer the cannon and successfully delay the Covenant assault on the ''Autumn'' by crippling an incoming [[CCS-class battlecruiser]] with a shot to its ventral [[energy projector]].<ref name="reach"/> | ||
The UNSC's postwar prototype flagship, {{UNSCShip|Infinity}}, is equipped with a number of dorsal turrets quite similar to the Mark 2488. During the initial skirmishes on the [[Forerunner]] [[shield world]] [[Requiem]] in [[2557]], these turrets were used to fend off the [[Didact]]'s [[Cryptum]], forcing the Didact to retreat.<ref>'''Halo 4''', campaign level ''[[Infinity (level)|Infinity]]''</ref> Several automated Onagers were mounted across [[Ivanoff Station]] and were used by the UNSC forces to defend the [[Composer]] from invading [[Covenant remnant]] forces under the command of the Didact himself.<ref>'''Halo 4''', campaign level ''[[Composer (level)|Composer]]''</ref> | |||
