Interestingly, when what became the A-10 Warthog was in the planning stages, the Air Force was told it needed a prop plane for the mission requirements. AF was having nothing of it, and demanded a jet aircraft. I think this plane, with a variable pitch propellor, will have more flexibility than the A-10. We'll see how this plays out and if the AF gets more of the prop driven LAA. I don't get the impression that they are intending to replace the A-10, but more to supplement it.
