The General Dynamics GAU-22/U Equalizer is a four-barrel 25 mm Gatling-type rotary cannon, designed specifically for use on Lockheed Martin’s F-35 Lightning II. The CTOL version of the aircraft will carry the gun internally, while the STOVL and CV versions use it as an external podded gun. The GAU-22/A’s major difference is the use of four barrels, rather than the five barrels on the GAU-12/U. The GAU-22/A is lighter, has a reduced rate of fire of 3,300 rounds per minute and an improved accuracy of 1.4 milliradians as compared to the GAU-12. This system is undergoing intensive testing and qualification. The weapon is currently produced by General Dynamics Ordnance and Tactical Systems.
