Ken, I will suggest that perhaps the A-10 mission, if it is to be taken over, will be assumed by rotary wing. There is a certain amount of doctrinal nonsense that somehow helicopter, airborne fires, don't provide close air support on the battlefield. Also, with the new guidance sysetms on weapons, that A-10 mission may not be delivered from comparatively low altitude, with a gun, should fixed wing be called on for close in fire support.
See also unmanned and armed aircraft. Reaper can bring you a 500 lb laser guided munition, among other things.
Think combined arms, in any case, and not just air superiority or purely air minded when establishing operational assumptions.
