A '''naval autocannon''', colloquially known as a '''naval coilgun''' and a '''[[Magnetic Accelerator Cannon|mini-MAC]]''', is an anti-ship [[coilgun]] turret mount which is installed on the [[warship]]s of the [[CMA Navy]] and [[UNSC Navy]]. They typically fire guided shells against long-range targets, and inert kinetic kill rounds at short-range.{{Ref/Book|HWF|Page=91}} As their name suggests, despite their massive size and calibre, naval autocannons are capable of fully-automatic fire when necessary. This allows them to be used in some limited capacity for the purposes of point-defence if needed,{{Ref/Level|HR|The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn|Detail=During the final defensive segment near the end of the level, the ''Autumn'' can be observed firing its two forward Spitfire coilguns at Covenant aircraft in the sky while the ship's point-defences are not firing at all. This level was created before the introduction of the naval coilgun concept in later written media, so may alternatively be considered simply an inconsistency.}} though this job is typically one left for the ship's [[point-defense gun]]s. Naval coilguns are generally installed inside turrets in configurations known as [[Wikipedia:Artillery battery#Naval usage|batteries]] - with between two and four individual guns in a single emplacement.{{Ref/Book|Enc22|Page=115}}

Naval autocannon turrets are most commonly found as the secondary armaments aboard the [[cruiser]]s of the CMA and UNSC - with these vessels generally being the only ones large enough to mount a large amount of the massive turret installations. UNSC [[battleship]]s do employ some autocannons though primarily focus on their much larger "super" MACs, while [[UNSC carrier|carriers]] may employ them in a limited capacity to augment their primary MAC in ship defence. Smaller ships such as heavier [[UNSC destroyer|destroyers]] and [[UNSC frigate|frigates]] may also mount a smaller number of naval coilguns, with some [[UNSC corvette|corvettes]] integrating them entirely into the raw spaceframe of the vessel. One such vessel, the {{Class|Lancer|fast-attack corvette|}}, has four [[LNT-450 naval coilgun]]s built into the basic superstructure of the ship in a manner similar to that of the keel-mounted primary [[Magnetic Accelerator Cannon]]s of larger vessels as opposed to the rotational turrets of its larger cousins. Naval coilguns are typically more prominent on the destroyers and frigates which do not see as much emphasis placed on their MAC systems - such as the {{Class|Diligence|light destroyer}}, {{Class|Hillsborough|heavy destroyer}} and {{Class|Strident|heavy frigate}}.

Naval autocannons had entered service by the late-24th century, with the {{Class|Mako|corvette}} equipping two and launched in [[2388]],{{Ref/Book|Enc22|Page=129}} and continued to see refinement throughout the next 150 years into the 26th century. By the 2560s, they have become a standard armament of human-made capital ships.

==List of naval coilguns==
Several lines of naval coilguns are employed in the naval forces of the [[Colonial Military Authority]] and [[United Nations Space Command]] - many of which have a number of models (usually denoted by "Marks" - eg the Mark 33 and Mark 40 Spitfire guns).

==Production notes==
On page 39 of ''[[Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo]]'', the {{Class|Strident|heavy frigate}}'s Mark 55 Castor NCG is referred to as a [[Railgun (fiction)|railgun]]. This is presumably an error, as the weapon itself is referred to on the same page and in other sources as a naval ''coil''gun. If this weapon does indeed canonically turn out to be a railgun, this may also indicate other "mini-MAC" artillery such as the [[Mark 2547 heavy railgun|Mark 2547]] and [[Mark 2555 heavy railgun|Mark 2555]] heavy railguns to also come under the naval autocannon schema.
