I was really against the AF getting rid of the A-10; but after seeing this war in Ukraine, I'm beginning to think their day has passed, too. It looks a lot like the grunt's life is a lot less secure, and it's never been a safe occupation from day one. In contested airspace it looks like any close air support is risky, and I can't see anything like an F-35 filling in for what an A-10 could do.
It seems like we spend too much time on expensive, flashy military toys while less sophisticated enemies are obsoleting concepts with something literally developed from toys. Not enough people with a fresh look asking "what if". All too often it seems in both military and industry innovation loses out to concepts of modern management, and considering that was basically the battle that Billy Mitchell tried to fight, it's a pretty bad look. Seems like we are expending far too much thought on war in the air without considering why war in the air is important ... to support the war on the ground that takes ground.
