WATCH: F-35B fires its gun for the first time

F-35B BF-01 completes the first ever aircraft-mounted test of the podded GAU-22/A cannon.

The GAU-22/A is the latest application of the GAU-12/U, which is a four-barrel version designed for use on the 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.

  1. I’m a big fan of the F-35, having followed the JSF programme for a few years.

    Will the external gun pod be shrouded with RAM?

    Also, will the internal gun will require the weps bay to open and then lower the gun to make it ready to fire?
