M61A1/M61A2 20mm Gatling Guns
lightweight, highly lethal combat support
for a variety of air, land and sea platforms
The M61A1 and M61A2 produced by General Dynamics Ordnance and Tactical Systems are externally powered six-barrel 20mm Gatling gun systems that offer lightweight, highly lethal combat support for a variety of air, land and sea platforms.
The M61A1 and M61A2 increases multiple-hit probabilities when compared to single barrel guns operating at lower rates of fire. The M61A1 and M61A2 weapons are based on the proven Gatling principle of operation and provide reliability up to 10 times greater than single-barrel guns.
The M61A2 shares the same features as the M61A1, but is 20 percent lighter. The M61A2 will meet or exceed the M61A1 gun's reliability, maintainability and supportability features. It is now available for applications where weapon system weight reduction is critical.
