Glad to be able to help Doug, I’m a huge fan of the A-10.
Sadly, the USAF need to pay for the F-35 so the Hog could be appearing more and more in this forum despite being capable until 2028!

Thanks everyone for the response.

The Hog has always had a problem with gun gases emitted by the GAU-8, during testing a pilot was forced to dismount after the engines stalled due to gun gas ingestion.
Nowadays a different propellant is used which reduces the effects of the gun gas.
However, in the early 80’s a contract was offered to anyone who could alleviate the problem.
The Battelle Company came up with a gun gas diverter , hence the different appearance in the photo.
It worked well but was discarded after stresses on parts of the aircraft including the gun mounts and longerons.

I seem to recall , possibly from the osprey colour series A10,that they may be gun gas deflectors ,They were aerodynamically shaped to push the gun gases away from the engines , to avoid stalling, I think they may have been experimental only, apologies if I’m wrong it’s been a few years since I’ve seen that book !

No idea what that is. Strange looking device.
