It's the only plane I could think of that was used by AF and carrier-based too.
Carrier landings are so hard on AC, need a plane designed specifically for that. Any other branch it's just extra weight
Bingo!
The other difference is that the Navy likes to have two engines in their fighter/attack aircraft, although several have been single engine - A-4, F-8, A-7, plus (obviously) all the piston fighter/attack aircraft.
