Same name, but many versions for interdiction, separate version, "Wild Weasle" for ground attack, different aviaonics, different airframes, different weapons, different structural mounting systems. Cannons are of limited use in interdiction missions, but necessary for ground attack versions. Air Force versions do not have tail hooks, or catapult launch capability, or strength in the frame to allow either. If an AF version ever managed to land on a carrier, it was into a net and, if it survived that, was probably lifted off by crane, or pushed overboard. I doubt it fits onto the elevator, or into the below deck hangers without wing folding capability. No AF or Navy version can really be considered to be the exact same aircraft, yet it makes a ton of sense to have similarities when such is possible and differences when not. The search for a universal platform starts and ends in the unicorn forest.
