GAU-23/AW/Linkless Feed Autocannon

The GAU-23/AW/Linkless Feed Autocannon is a weapon used by the UNSC Marine Corps, mounted on AV-22 Sparrowhawks, AV-14 Hornets and AC-220 Vulture gunships.

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. 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.

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 during the Harvest campaign, Battle for Arcadia and Battle of the Etran Harborage.

Trivia
Dirt makes mention of a chin-mounted machine gun on a Hornet aircraft, though it is unconfirmed if this is the GAU-23.
