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

18

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.

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?

I don’t know why they’re showing an external pod. They showed a video of them test firing the f-35s gun, but it was internal on the left side behind a flap.

Hi, the F-35B uses an external pod.

Why just the ‘b’ varient?

Elliott Miller the C variant uses it too

Pod?

Just looked at the schematics for each varient, and it’s only the ‘a’ varient that has the internal gun. Why?

It’s likely got to do with the internal space being used for the lift fan, in the centre of the fuselage. However, I’m guessing.

I would agree relevant to the ‘b’. But why do you think the ‘c’? Weight perhaps (carrier launch weight)?

I think it is to do with weight and the option to have it or not. Also proberbly to aid in loading and safty on confined carriers. Improving sortie rate.

Inyerestingly the pod for the B and C variants carries more ammunition than the internal gun of the A.

And to answer another poster. The pod is stealthy yes. And allows the weapons and all other doors to function without interference.

I wonder how this bird will perform for close air-support? Also, I wonder how “brrrrrt” it sounds while strafing.

Extremely well with its sensors, especially SLAR and of course precision munitions such as Brimstone and Spear.

Loved the gun test video. I was impressed at the tight group that gat fires.
