And as for replacing the A-10? I think not..!
As we on this side of the pond(s) discovered (and keep discovering since about 1989), there is no replacement for the A-10.
I seem to recall attempts just before Op Desert Storm to get the A-10 retired, all efforts coming from the USAF side, not the Army. (Nor the Marines).
The Warthog flies yet, and is a favorite of ground commanders.
