Editing Magnetic Accelerator Cannon

{{Era|UNSC|HCW|Post}}

The '''Magnetic Accelerator Cannon''' ('''MAC'''), also known as the '''Mass Accelerator Cannon''',<ref>'''[[Halo: Contact Harvest]]''', Chapter 7, ''page 119''</ref><ref name="visual"/> is a weapon system employed by the [[United Nations Space Command]] on its warships and [[orbital defense platform]]s. Essentially large [[Wikipedia:coilgun|coilguns]], MACs serve as the primary armament of [[UNSC Navy]] warships and weapon platforms.

==Overview==
===Operational design===
The theory behind the operation of a Magnetic Accelerator Cannon is the same as that of a coilgun. The system is a linear motor consisting of a series of magnetic coils which accelerate a metal projectile through a barrel up to high velocity. This technology is not to be confused with that of a [[railgun]], in which a projectile is electromagnetically accelerated between two conducting rails.

===Firing operation===
[[File:Coilgun animation.gif|thumb|250px|The basic design of a coilgun.]]
The firing process uses [[wikipedia:electromagnetism|electromagnetism]] to fire a metal slug at high velocity. An extremely large amount of current is put through the first solenoid, (coil of conducting wire), which creates a strong magnetic field that attracts the slug. As the slug passes into the solenoid, the solenoid is quickly turned off and the second solenoid, which is closer to the muzzle, turns on, which attracts the now higher-velocity metal slug just like the first solenoid, and the process is carried on.

A shipboard MAC draws power from the ship's reactor and requires a charge of the weapon's magnetic coils in order to be fired. The time it takes to bring the MAC's systems to full charge on a UNSC vessel is the deciding factor during in-combat use. Thus, while a vessel may not run out of ammunition for a long time, (depending on the size/weight of the slugs and the capacity of the ship), a [[commanding officer]] has to carefully analyze the situation of a battle and use his shots strategically. The weapon could be fired even when not at full charge, but the velocity of the projectile will be greatly diminished.

[[Orbital defense platform]]s have the same firing process, though they launch much more massive projectiles, (3,000 tons), with greater frequency. At the moment a slug leaves an ODP-mounted MAC's muzzle, a pair of thrusters on the bottom side of the station fire for a few of seconds to counteract the acceleration imparted to the station.<ref name="Cairo">'''Halo 2''', campaign level ''[[Cairo Station (level)|Cairo Station]]''</ref>

===Ammunition===
Payloads used in the Magnetic Accelerator Cannon weapon delivery system alternates with the platform which the weapon is hosted; warship models tend to use ferric, ferrous, or [[depleted uranium]] cores whereas orbital platform models commonly use ferric tungsten rounds.<ref name="for283"/>

The standard [[UNSC frigate|frigate]]-based MAC fires a 600-ton slug around 30 kilometers per second. The high muzzle velocity provides the slug the kinetic energy and momentum necessary to damage a target and partially mitigates its unguided nature and its lack of maneuverability.<ref name="for108">'''Halo: The Fall of Reach''', ''page 108'' (2001 edition); ''page 130'' (2010 edition)</ref> A "Super MAC" mounted on one of the Reach orbital defense platforms<ref name="CanonFodder70"/> was capable of firing a 3,000-ton slug at nearly .04''[[wikipedia:speed of light|c]]'', or around 12,000 kilometers per second.<ref name="for283">'''Halo: The Fall of Reach''', ''page 283''</ref>

===Aiming===
The size of a Magnetic Accelerator Cannon is such that it is normally an integral component of a warship's structure. Orbital defense platforms are built around the massive weapon. A dedicated targeting computer or an AI is typically required to aim or fire the cannon,{{Citation needed}} as the projectiles are unguided.

==Types==
There are numerous variations of the MAC technology, grouped under several "Mark"-based designations. MAC systems are also sometimes roughly divided between "heavy coil" and "light coil" guns.<ref name="bul10"/><ref>'''[[Halo 4: The Essential Visual Guide]]''', ''page 191''</ref> All known frigate classes carry one MAC system, whereas the standard [[UNSC destroyer|destroyer]]<ref name="twomacs">'''Halo: The Fall of Reach''', ''page 139''</ref> and the {{Class|Marathon|heavy cruiser}} carry two MACs.<ref>'''[[Halo Encyclopedia]]''', ''page 251''</ref> The Navy's post-war flagship, {{UNSCShip|Infinity}}, is armed with four Magnetic Accelerator Cannons.<ref name="bul10">[http://blogs.halowaypoint.com/Headlines/post/2012/10/10/The-Halo-Bulletin-101012-.aspx '''Waypoint''': ''The Halo Bulletin: 10.10.12'']</ref>

===Frigates and destroyers===
[[File:Mac.jpg|250px|thumb|A squadron of UNSC frigates firing their MACs at the Covenant's [[Forerunner Dreadnought]].]]
A standard [[UNSC frigate|frigate]]-mounted MAC averages at {{convert|183|m|ft}}.<ref name="visual">'''[[Halo: The Essential Visual Guide]]''', ''page 114''</ref> It can fire a 600-ton ferric-tungsten projectile with a depleted uranium core at 30,000 meters per second, and takes several minutes to recharge to full capacity between shots.<ref name="for108"/> The large amount of energy needed to fire the weapon is particularly onerous on a warship, and the extended recharge time is a significant factor in combat against [[Covenant]] warships. As a result, MAC rounds are often fired at significantly below their maximum potential velocity by an order of magnitude or more. This results in the impacts being much weaker, but the MACs can be fired far faster and such firepower is still sufficient to destroy the shields of most Covenant warships after a few hits.<ref name="small MAC velocity" group="note">In every single space battle scene in the novels, including [[Halo: The Fall of Reach]] and [[Halo: Ghosts of Onyx]], MAC slugs are described as cleanly penetrating from one end of Covenant ships and out the other, as well as punching holes in whatever they hit. This would be impossible if the slugs were actually going at 30 kilometers per second on every occasion, as past around [http://www.sciencedirect.com/science/article/pii/S0734743X06001242 1.7 km/s], the tungsten slugs would create [https://en.wikipedia.org/wiki/Hypervelocity hypervelocity][http://www.esa.int/Our_Activities/Operations/What_are_hypervelocity_impacts impacts]. Therefore, the coilguns must be "dialed down", trading pure power and velocity for refire rate (as a point of comparison, a 600 ton object traveling at 1 km/s would impact with the force of 65 tons of TNT). This matches the depiction of MACs in the games, where they have a refire rate of only a few seconds and muzzle velocities of only a few kilometers per second at most (as in the last cutscene of [[Cairo Station]] in Halo 2: Anniversary). It also fits the velocity of the MAC slugs in [[Halo: The Fall of Reach - The Animated Series]], and the description of a MAC propelling slugs to [http://www.merriam-webster.com/dictionary/supersonic supersonic] (between 340 m/s and 1.7 km/s) velocities on pg. 264 of [[Halo: First Strike]].</ref> The standard Magnetic Accelerator Cannon is sufficient to destroy any human vessel or severely damage an unshielded Covenant vessel.<ref name="small MAC yield" group="note">The ''Halo Encyclopedia'' erroneously states that a typical shipboard MAC slug is fired at .4''c'' (40% the speed of light), which would probably cause the projectile to be atomized by its own acceleration. The weapon's explosive yield is listed as equivalent to 1.17 teratons of TNT. This would release an average of 21,667 times more energy than [[Wikipedia:Tsar Bomba|Tsar Bomba]], the largest nuclear device in history, which is generally agreed to have released between 50 and 58<!--The figure used is 54 megatons for simplicity's sake.--> megatons (210 to 240 petajoules) of TNT-equivalent energy.</ref>

===Specialized and modified versions===
The standard MAC can be enhanced with booster capacitors which allow the weapon to be fired three times per charge rather than once per charge. This improved technology was only known to be implemented with the {{UNSCShip|Pillar of Autumn}} prior to the [[Fall of Reach]].<ref name="for275">'''Halo: The Fall of Reach''', ''page 275''</ref> The modified weapon, known as the ''Mark II, Light Coil - 56A2D4/MAC'',<ref name="waypointarticle">[https://www.halowaypoint.com/en-us/universe/vehicles/pillar-of-autumn '''Halo Waypoint''': ''Pillar of Autumn'']</ref> charged faster than the standard version, though this is likely due to the ''Pillar of Autumn''<nowiki/>'s advanced reactors.<ref name="for275"/> Also exclusive to the ''Pillar of Autumn'' along with the modified MAC were newer and lighter MAC rounds that had less dense ferrous core, but a harder outer layer of tungsten carbide.<ref name="for275"/>

UNSC [[orbital defense platform]]s, {{Class|Punic|supercarrier}}s and the {{UNSCShip|Infinity}} mount larger and more powerful versions of the standard Magnetic Accelerator Cannon, nicknamed the ''"Super"'' MAC or the ''"big stick"''. An orbital defense platform's cannon is {{convert|802.2|m|ft}} long,<ref name="visual"/> with the platforms present in orbit of Reach, which were among the most powerful ever built,<ref name=CanonFodder70>[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-looking-glassed '''Waypoint''': ''Canon Fodder - Lookin Glassed'']</ref> being capable of firing a 3,000-ton ferric-tungsten rounds at .04''c'' or 4% of the speed of light, impacting with a massive amount of kinetic energy.<ref name="for283"/><ref name="big MAC yield" group="note">''The Halo Encyclopedia'' claims that a Super MAC slug is fired at .5''c'' (50% the speed of light), and that its explosive yield is around 9.98 teratons. This would result in an explosion with around 184,815 more energy than the aforementioned Tsar Bomba, or roughly one tenth of the energy released by the Chicxulub impactor which wiped out the dinosaurs 65 million years ago.</ref> Most UNSC and Covenant vessels are destroyed by this weapon, with shielded Covenant destroyers being shattered into "a million fragments" upon impact.<ref>'''Halo: The Fall of Reach''', ''page 297'' (2001 edition)</ref> However, these guns, even with assistance from the UNSC Home Fleet, were not powerful enough to pierce the shields of the [[Ur-Didact]]'s flagship, ''[[Mantle's Approach]]''. Only the {{UNSCShip|Infinity}}'s MAC guns managed to pierce ''Mantle's Approach's'' shields at a closer range and cause some damage and even then only after [[John-117]] managed to disable some of the ship's point-defense guns using an [[F-41 Broadsword]].<ref name="midnight"/>

By receiving power from [[Orbital defense generator|ground-based power plants]], orbital defense platforms could achieve recharge and reload times as short as five seconds.<ref name="Cairo"/><ref name="for283"/>

However, the ''Infinity'' had to get within relatively close range and needed [[John-117]] to disable some of the ''Mantle's Approach's'' point-defense guns to take the shot. Even then, ''Infinity's'' shot caused relatively minor damage that was quickly sealed by the powerful Forerunner ship. Notably however, these MAC guns were the only weapons to breach the Didact's shields at all with even the MAC guns of Earth's orbital defense platforms failing to do any damage.<ref name="midnight">'''Halo 4''', campaign level ''[[Midnight]]''</ref>

{{Main|Mark 2488 Magnetic Accelerator Cannon|Mark 2551 Magnetic Accelerator Cannon}}
The Mark 2488 Magnetic Accelerator Cannon, informally known as the Onager, is a relatively small Magnetic Accelerator Cannon used for static defense. A manned version was used to defend the ''Pillar of Autumn'' on Reach.<ref>'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref> The Mark 2488 fires a 15cm round with up to 1.1 gigajoules (0.25 tons) of kinetic energy. It is 32.6 meters long,<ref>'''[[Halo 4: The Essential Visual Guide]]''', ''page 75''</ref> making a standard frigate-mounted MAC 5.6 times larger by length and roughly 177 times larger by volume, assuming similar dimensions. After the war, a new automated variant, the Mark 2551, was used by the UNSC ''Infinity'' on Requiem.  [[Ivanoff Station]] was also equipped with several automated Mark 2551 Onagers.<ref>'''Halo 4''', campaign level ''[[Composer (level)|Composer]]''</ref> The setback of the new Mark 2551 however, it cannot be operated manually unlike Mark 2488. When the defense network is offline, the Mark 2551 MAC was rendered inoperable like how UNSC ''Infinity'' MAC network is offline while Mark 2488 can still manually operated without reliance on defense network.

==Related technologies==
===M68 Gauss Cannon===
{{Main|M68 Gauss Cannon}}
The M68 Gauss Cannon is a weapon mounted on the [[M12G1 Light Anti-Armor Vehicle]] as well as on stationary turrets. It utilizes the same coilgun technology used in MAC, but on a smaller scale.

===M92 Principle Gauss Cannon===
{{Main|M92 Principle Gauss Cannon}}
The M92 Principle Gauss Cannon is a weapon system of similar MAC mechanics that runs along the length of the [[Open Frame 92/Extra-Vehicular Activity]].

===M99 Stanchion Gauss Rifle===
{{Main|Model 99 Special Application Scoped Rifle}}
The M99 is a man portable anti-matériel and anti-personnel special application weapon using 5.4mm/.21 caliber rounds. Like the M68 Gauss Cannon, it utilizes the same coilgun technology as a MAC, only on an even smaller scale. Though smaller than conventional ammunition, these rounds are accelerated to speeds fast enough to travel long distances with almost no change in trajectory, punch through any obstructing materials, hit their target, and still retain significant kinetic energy.

===Mass drivers===
{{Main|Mass driver}}
The mass driver is an orbital launch assembly designed to propel low-weight payloads into orbit, otherwise known as orbital lifting, or to deliver them across a planetary system. The operating principle of the mass driver is essentially the same as that of the Magnetic Accelerator Cannon: it is a large coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload.
 
While not a purpose-built weapon like the Magnetic Accelerator Cannon, these platforms are still potent weapons of opportunity. While never formally incorporated as a weapon, mass drivers have been used at as defensive magnetic accelerator weapons at [[Harvest]], [[the Rubble]], and [[Reach]].

==Gameplay==
[[File:MAC Blast.JPG|thumb|right|The MAC Blast in use.]]
===''Halo Wars''===
{{Quote|Use the Spirit of Fire's awesome Mass Accelerator Cannon to incinerate enemy troops.|In-game description.}}
In ''[[Halo Wars]]'', the '''MAC Blast''' ability allows the player to use the {{UNSCShip|Spirit of Fire}}'s [[11A2R1 naval coilgun battery|point-defense MACs]] for pinpoint [[orbital bombardment]]. It is mainly used as a support weapon to help the UNSC penetrate heavy Covenant defenses and Covenant bases, and is a potent weapon against [[Type-47B Scarab|Scarabs]].

In [[Skirmish]] and multiplayer, the MAC Blast can only be used if [[Captain (Navy)|Captain]] [[James Cutter]] is selected as the player's leader character. In the campaign, the MAC Blast is available in several missions, most notably ''[[Dome of Light]]'', during which the player is granted access to forty rapid-fire MAC rounds to destroy a Covenant base that was located under a Covenant energy shield dome until part of the dome was overloaded using [[M145D Rhino|Rhinos]].
{{clear}}

===''Halo Wars 2''===
In ''[[Halo Wars 2]]'', the MAC Blast has been upgraded by [[Ellen Anders]] and [[Isabel]] into '''MAC Blast EMP''', which is very effective against all mechanical units. The EMP MAC is only available during the campaign mission "[[The Cartographer]]", where it is used to fire on a swarm of [[Aggressor Sentinel]]s defending a Forerunner conduit. In Multiplayer and Blitz Mode, the MAC Blast is exclusive to Isabel and [[Avery Johnson/Gameplay|Sergeant Johnson]]. Isabel uses standard MAC rounds, while Johnson uses EMP rounds.

===Changes from ''Halo Wars'' to ''Halo Wars 2''===
*MAC rounds can no longer can be upgraded via the Armory.
*Leader Points now can be used to upgrade MAC damage.
