The '''magnetic accelerator cannon'''{{Ref/Reuse|WFG}} | The '''magnetic accelerator cannon''',{{Ref/Reuse|WFG}} also referred to as a '''mass accelerator cannon'''{{Ref/Reuse|CH7}} or '''MAC''', is a type of heavy weapon system employed by [[human]]ity, primarily the spacecraft of the [[United Nations Space Command]]. Within the UNSC, MACs are defined as a heavy weapon that fires a sizeable ferric-tungsten round at supersonic velocities from the bow of a capital ship, [[orbital defense platform]] or mounted driver emplacement.{{Ref/Book|Id=EVG114|EVG|Page=114}}{{Ref/Book|Id=Enc22P384&385|Enc22|Page=384-385}}{{Ref/Site|URL=https://www.halowaypoint.com/news/the-new-halo-encyclopedia-is-out-today|Site=Halo Waypoint|Page=The New Halo Encyclopedia is Out Today|D=11|M=03|Y=2023}} MACs are coilguns employing Asynchronous Linear Induction Motor (ALIM) technology{{Ref/Reuse|EVG114}} and are typically used in military applications, though similar technology can be used in civilian [[mass driver]]s for industrial use. | ||

MACs are capable of firing a wide array of munitions, depending on bore and model.

Some MAC rounds are extremely dense and constructed of ferric tungsten,{{Ref/Reuse|EVG114}} noted by Captain [[Wallace]] of the frigate {{UNSCShip|Commonwealth}} as a "heavy round".{{Ref/Novel|Id=FOR12|FOR|Chapter=12}} In the case of the MACs fitted onto the refit-colony ship {{UNSCShip|Spirit of Fire}}, the rounds fired from its MACs are "low-mass"{{Ref/Book|Id=HWManual|Halo Wars Manual|Page=24}} or consist of three-hundred-ton depleted uranium slugs.{{Ref/Novel|Id=DW15|HDW|Chapter=16}} The MAC of the ''Spirit of Fire'' was later modified in a special project conducted by [[Ellen Anders]], resulting in a specialised MAC capable of firing rounds that emit an [[Electromagnetic pulse|EMP]] upon impact.{{Ref/Level|HW2|The Cartographer}} Other munitions that can be fired from MACs include semi-autonomous drone missiles{{Ref/Book|Id=WF32|HWF|Section=Destroyers|Page=32-33}} and for the larger 27 metre guns of {{UNSCShip|Infinity}}, even include cargo pods and small spacecraft.{{Ref/Book|Id=WF42|HWF|Section=[[UNSC Infinity|Infinity]]|Page=42-43}} A special kind of MAC round fired by the refit-{{UNSCShip|Pillar of Autumn}} was composed of a ferrous core and an outer layer of tungsten carbide, which allows the round to splinter on impact with an enemy vessel, similar to the [[shredder round]]s fired by an [[assault rifle]].{{Ref/Novel|Id=FOR29|FOR|Chapter=29}} | ||

Contrary to the aforementioned examples, the ''Halcyon''-class light cruiser does not employ a heavy MAC, but rather a light one - likely the cause of the ship being infamous for being undergunned within the UNSC fleet.
