If the AF leadership wasn’t so shortsightedly stubborn about the Army flying fixed-wing aircraft they’d have transferred the A-10s to Army aviation a long time ago - that’s a win-win proposition since they could retain depot-level maintenance of the iron and the training mission (in the whacky world of military budgeting those activities can generate “profits” - at least on paper which is all that counts there) while handing the operational and sustainment costs over to the Army.
But in the long run RPVs are going to replace aircraft like the A-10 and AC-130 (and conventional cargo aircraft for “the last tactical mile”). Lower costs (all the costs are lower for RPVs - development, acquisition, sustainment, employment, training, maintenance) plus the US military’s culture of casualty avoidance will push RPVs into CAS and logistics missions. Why risk multimillion dollar manned aircraft and their crews to put ordinance or pallets on targets in the battle zone when a “drone” can do it cheaper and safer?
I was lucky enough to spend some time at Myrtle Beach before it was shut down - watching the A-10s fly over the beach on their way to the offshore range was really cool. Plus the handful of times I watched them take-off at Kirkuk during my short time there was even better. The A-10 is an amazing plane but, for better or worse, soon to be obsolete.
