25mm GAU-12/U Gatling Gun

25mm GAU-12/U

Externally Powered Gatling Gun

The GAU-12/U 25mm gatling gun has significant muzzle energy and combat lethality. These factors, when combined with a maximum firing rate of 4,200 shots per minute, provide an effective weapon for a variety of combat missions.

Each of the GAU-12/U’s five barrels contain its own breech bolt assembly, which fires once per gun revolution. This ensures extended barrel life by distributing firing loads over all five barrels.

Continuous rotary motion reduces impact loads on gun components, providing extended parts life and high reliability.

The GAU-12/U provides air-to-air, ground-to-air and air-to-ground firepower for the U.S. Marine Crops AV-88 Harrier II aircraft, the Light Armored Vehicle – Air Defense (LAV-AD) and the U.S. Air Force AC-130U Gunship.
