Yes, an interesting read. But, IMO, its an outdated theory. The A-10 is great at CAS because it can carry an impressive weapons load and can loiter for longer durations than an F-16 with a smaller load. But converting to a drone would take away it's one trump card. The gun. CAS is more than dropping JDAMs and LGBs. If you rewrite the mission to only include that weapon employment plan, you might as well save the money and stick with the current Predator and Reaper since they are already doing that very thing. Saturate the air with those and you don't need a $30Mil QA-10 that, oh by the way, still needs a tanker and other expensive support.
I just dont think our remote piloting programs are up to the challenge of engaging ground targets with all of what the A-10 brings to the fight.
