Regarding the Army/USAF turf wars, keep in mind how the A-10 came to be. After the 1966 Army/Air Force agreement restricting Army operation of fixed wing aircraft and USAF operation of rotary wing aircraft, Army developed the AH-56 Cheyenne helicopter. But there were two political problems: 1) the Cheyenne had eye watering performance and was going to be a fantastic aerial tank killer. USAF viewed aerial tank killing as their exclusive turf, never dreaming a helicopter could do that mission. 2) the Cheyenne was a compound helicopter with a pusher prop and small fixed wings, which USAF argued violated the 1966 agreement. The turf battle raged for years and was finally resolved when Army agreed to cancel the compound Cheyenne and develop the AAH pure helicopter tank killer, which ultimately became the AH-64 Apache, and USAF agreed to develop the fixed wing A-X tank killer, which became the A-10. The turf wars have calmed down considerably, but not enough for USAF to ever allow Army to operate F-35s. The F-35 operates on turf which USAF views as forever and always belonging exclusively to them.
