I think the AF was trying to control all FW flying, they tried and failed to seize naval aviation after WW-II. I think the AF controlled or tried to control RW also but the army threw the yellow flag on that.

The AF never really wanted the A-10, they did not want to be in the cas bidness at all...they only took it to keep others from getting a FW tactical jet. When budgets got tight after the cold war they tried to discard all of the A-10's in order to fund a few more pointy nose airplanes, o-clubs, and golf courses, but big DoD and congress canx that idea. Congress does occasionally display remarkable vision.

When the AF tried to shut it down, the marines were on the verge of taking some of the airframes...that would have been a good thing. Maybe next time.
