This is a limited program to lease some airplanes for a few specific customers. The A10 aint commin' back. Fairchild has long since shuttered their doors and Boeing wants to sell new airplanes, not parts for someone elses airplane. The OV-10 died the slow death because in order to get enough to do anything with one of the services would have to give up the sexy jets to get more of the ignoble prop planes. That of course means less money to boot. So which branch will be first in line to cut thier prestige and budget? Surprisingly there are no takers
Of course there is the US Army, but they cant get their head out of their collective buts long enough to get a new ARH when no one is trying to stop them. Their is no way the USAF would let them get another fix wing with ordinance, hell the USAF just back-doored them on the Spartan intra-theater transport!
