How about instead of paying ~$178M per plane for sexy and utterly stupid human-in-the-plane stealth concepts, we refit the existing A10s to fly as cheap, reliable, remotely piloted drones.
I'll do it for $10M per plane. If we refit all of the 238 existing planes in service, total cost would be $2.38 billion. Since I'll be a government contractor I'll up-charge $10 billion for the entire program, and it will still cost less than 1% of the F-35 program costs so far.
