That was sort of the point for my asking the question about the ski-jump/ramp. US naval aviators don't have the benefit of it, but the Brits use it with their Sea Harriers. More than likely they would have had a VMFA detachment & just painted roundels on the jets. The pilot/aviators would be called "exchange pilots". No need for a shake & bake version of the AVG/Flying Tigers.
VMA. VMFAs have never been Harrier equipped.
