This is because the [[M12 Force Application Vehicle|Warthog]]'s machine gun turret uses .50 caliber rounds as well, but they are much less damaging. The GUA-23 Autocannon must use a 15mm or higher caliber round to be considered an autocannon. Hence, the GUA-23 seems to be a 25 or 30mm cannon. |

| ==Overview==
| |
| ===Design details===
| |
| The GAU/23 is a tri-barreled autocannon found equipped on many UNSC aircraft. It is capable of engaging a number of enemy units of various types, ranging from infantry, to armored vehicles and aircraft.{{Ref/Generic|[[Halo Wars Limited Edition]]|[[Personnel profile]] - [[Ellen Anders]]|LocalArchive=:File:HWDE Anders LeaderProfile.jpg}} The version mounted on Sparrowhawks can fire the full range of 20mm aircraft ammunition, though the standard loadout is either [[M718 SAPHEI]] or [[PGU-42/B API]], with a [[depleted uranium]] core.{{Ref/Site|Id=units|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-local-units|Site=Halo Waypoint|Page=Canon Fodder - Local Units|D=30|M=06|Y=2021}}
| |
| | |
| When mounted on certain variants of the AV-14 Hornet, the GAU/23 is mounted on the craft's chin as a rotary cannon. Two of the weapons can be mounted on the wingtips of the Sparrowhawk, while the AC-220 Vulture can host four wing-mounted guns.
| |
| | |
| ==Operational history==
| |
| During the early [[Human-Covenant War]], the GAU/23 was mounted on variants of the AV-22 Sparrowhawk, AV-14 Hornet and AC-220 Vulture gunships employed by the {{UNSCShip|Spirit of Fire}} during the [[Harvest campaign]], [[Battle for Arcadia]] and [[Battle of Trove]].{{Ref/Game|HW|In-game models}}
| |
| | |
| ==Notes==
| |
| There is discrepancy among sources as to the GAU/23's ammunition type. The ''[[Halo Wars: Official Strategy Guide]]'' makes note that the GAU/23 fires [[:Wikipedia:.50 BMG|.50 BMG]] ammunition, which would make it [[12.7×99mm Armor-Piercing]] ammo similar to that used by the [[M41 Vulcan]]. The later ''[[Halo: The Essential Visual Guide]]'' indicates the weapon to fire 30mm ammunition, while a later [[Halo Waypoint]] [[Canon Fodder]] post focusing on the Sparrowhawk identifies the ammunition type as 20mm.{{Ref/Reuse|units}} This article assumes the latter source as definitive information.
| |
| | |
| Additionally, the described properties of the GAU/23 as seen on the Sparrowhawk and Hornet in ''Halo Wars'' do not match the appearance of the weapon used by the Vulture gunship. The former two aircraft use the GAU/23 as a tri-barrelled autocannon for light targets, while the Vulture appears to only have one barrel per weapon firing at a slow rate of fire.
| |
| | |
| ==Trivia==
| |
| ''[[Dirt]]'' makes mention of a chin-mounted machine gun on a Hornet aircraft, though it is unconfirmed if this is the GAU-23.{{Ref/Anthology|Evo|Dirt|Page=113}}
