F-22A 20mm Gatling Gun System

The F-22A fighter is armed with the M61A2 20mm Gatling gun system produced by General Dynamics Ordnance and Tactical Systems. The fixed-forward internal gun sys­tem provides maximum firing rate performance.

The F-22A armament system features the lightweight M61A2 20mm Gatling gun and linear lin­kless ammunition feed system. The M61A2 provides up to 10 times the reliability of single-barrel guns, fir­ing at 6,000 shots per minute and placing a controlled dispersion of projectiles in the path of the target.

The linear linkless ammunition feed system features state-of-the-art composite and unique gun-feed technologies to provide high reli­ability at minimum weight. GD-OTS ammunition storage and handling systems have been used in all mod­ern U.S. front-line fighter aircraft.

The F-22A linear linkless ammu­nition feed system is compatible with three GD-OTS loading systems, including the Universal Ammunition Loading System, the Ammunition Loading System and the Universal Delinking Loader. The ALS and UALS systems significantly reduce manpower requirements and aircraft turnaround time by eliminating the need for linked ammunition.
