Someone must have made this meme to hurt nerds like me.
- Vought's F-8 Crusader was a Navy daytime fighter, fielded in 1955, and the first supersonic carrier-capable jet.
- Ling-Temco-Vought A-7 Corsair II was an attack aircraft, developed by the same company (after a merger) in response to a Navy requirement for a light attack aircraft to replace the A-4 Skyhawk. The design was heavily based on the older F-8. This was done in the early 1960s and the A-7A was flying in Sept 1965 and entered service with the Navy in 1967.
- The Air Force was forced by the Army to buy a slower aircraft that would be better at close air support than their F-100 and decided to get an A-7 as well. Their variant was called the A-7D, and the first prototypes flew in 1968.
So yes, the Air Force decided to buy their own version of the A-7, a jet that was built for carrier ops and already serving in the Navy (just like with the F-4 Phantom), but that has nothing to do with the older F-8 that only ever served in the Navy and looks a lot like the A-7.
To make it worse, both jets pictured are Navy jets. Aargh
