GAU-19/A Aircraft Armament - Externally Mounted Gatling Gun
The externally mounted version of the 12.7mm GAU-19/A three-barrel Gatling gun produced by General Dynamics Ordnance and Tactical Systems provides high-rate-of-fire firepower in a small, lightweight weapon system.
The weapon is effective in both air-to-air and air-to-ground missions. The GAU-19/A gun is installed within a fixed-forward mount that can be attached to standard 14-inch NATO stores racks or lightweight mount, which attaches directly to a universal stores pylon.
The GAU-19/A provides highly effective air-to-ground firepower against area suppression and point targets, such as light armored vehicles. Its high rate of fire, combined with the 12.7mm ammunition's short time of flight, permits reduced exposure time while the gunner is unmasked.
The system is ideally suited for scout or utility helicopters and light fixed-wing aircraft. It features an internal recoil system that reduces gun recoil to the airframe. This system can be coupled with a variety of linked ammunition feed systems that can, in turn, be tailored to fit a variety of applications.
The GAU-19/A has an automatic safing and clearing cycle. This ensures no live rounds are left in the gun and the firing mechanism is in a defeated position.
