GAU-19/B .50 Caliber Gatling Gun

lightweight, reliable, lethal

General Dynamics Ordnance and Tactical Systems manufactures the lightweight GAU-19/B Gatling gun for application on a variety of air, land and sea platforms, including helicopters, fixed wing aircraft, land-based vehicles, naval vessels and high-speed patrol boats.

With a rate of fire of 1,300 shots per minute, the .50 caliber
GAU-19/B provides superior firepower in a lightweight system. The total system weight of the three barrel GAU-19/B is neutral to that of a single barrel machine gun.

Three barrels, .50 caliber and 1,300 shots per minute all add up to one effective weapon system.

The simple, low-cost weapon system offers minimal maintenance and high reliability: GAU-19/B has an unmatched 40,000 mean rounds between failure. Initial scheduled maintenance begins at 35,000 rounds.

The GAU-19/B uses standard NATO .50 caliber M9-linked ammunition. The gun’s automatic clearing cycle ensures live rounds are not left in the gun. Low maintenance, light weight and devastating
firepower make the GAU-19/B the ideal weapon system for air, land or sea operations.

The GAU-19/B is effective in both air-to-air and air-to-ground missions. The weapon provides highly effective firepower against area suppression and point targets, as well as being ideally suited for utility, scout and attack helicopters and fixed-wing aircraft.

Mounted on armored personnel carriers or utility vehicles, such as the High Mobility Multi-Purpose Wheeled Vehicle, the GAU-19/B offers a high rate of fire in a simple, low-cost weapon system and produces devastating firepower against light vehicles
and ground forces. Installed as secondary armament on larger weapon systems, the GAU-19/B affords protection against close-in ground threats and provides air defense capability.

The GAU-19/B is ideal for use on a variety of surface navy ships and patrol boats. On light patrol boats, the GAU-19/B provides lethal suppressive firepower.
When installed on larger naval craft, the weapon system offers close-in protection against smaller seabased threats. Firing at 1,300 shots per minute, the GAU-19/B provides unparalleled firepower to counter both air attacks and high-speed surface threats.
