Re: A-10 is not a 1-service fighter
I expect that the USN and Marines did ask for a Navy version of the A-10 originally, but probably politics within the Pentagon stopped it. Turf wars among Flag Officers can be really nasty. I imagine the Corps wishes it did have its own version of the Stuka or Sturmovik, but the down side would have been that a Navy A-10 could not have flown CAP over the carriers.
