So, time for a quick round-up of the results so far: we're stuck with the A-10C because WWI generals didn't adapt tot the changing reality that CAS should be performed in a COIN situation where millions die, often by 5.56 bullets that proved to be superior to the 7.62x39. A-10's came to the rescue of troops in contact after turning the tail to the republican guard because the Gulf war was erroneously started before the F-35 was fielded with its superior SDB I missile, that we should not confound with the SDB II that actually would fit in the cargo hold of the AC-130, which is by far the most superior CAS aircraft for conflicts that unfortunately turned obsolete when the F-22 came online.
Contrary to artillery, the F-35 has enough fuel and range to stay away from CAS, which is already overcrowded with all the jets, transports, bombers and drones overhead that compete to perform this task better than the A-10 that was never designed for it in the first place. Instead, given its stealth the F-35 can sneak away out of the conflict unharmed, not so bad for a plane inspired by the flight dynamics of an albatros!
