I'm talking about a peer fight also. Ground warfare is changing in unpredictable ways. The way we trained for the heavy fight for the last 75 years is obsolete. There are no magic ray beams to make drones go away.
The media focuses on small FPV attack drones, but the impact on ISR is more important. Both sides now have 24/7 omnipotent observation of the FLOT to a depth of 50km. Anything that moves is seen immediately, and anything seen gets hit with precision munitions within minutes. Operational level maneuver gets shut down before it starts.
The other big issue is long range missiles. China now has thousands of missiles capable of hitting any air base in the Pacific. Dispersion will be necessary for survivability.
IMO it makes sense to keep a platform designed for ground attack, as a hedge against the future. It also makes sense to keep an aircraft capable of operating from austere environments and less than pristine runways.
Annual sustainment cost for 3 squadrons of A10's is 350 million, including modernization. That would buy three F35's.
I love and admire the Air Force. But history proves their leadership occasionally has to be forced to commit resources to support the ground fight.
"You may fly over a land forever; you may bomb it, atomize it, and wipe it clean of life - but if you desire to defend it, protect it, and keep it for civilization, you must do this on the ground, the way the Roman Legions did - by putting your soldiers in the mud." -- TR Fehrenbach
