The real problem is the F 35. The USAF can’t afford the F35 without divesting other platforms. CAS has always been the lowest priority for the USAF so it is not surprising the only USAF platform that is dedicated to the CAS role is going to be on the chopping block
Unfortunately if the A10 was retired it won’t get replaced by an equivalent number of other aircraft. History has shown that it is always better to have more tools in the war fighters toolbox.
