“One Size Fits All” worked with the F-4 Phantom (Navy, Marines and Air Force) though. There were Photo Recon, ECM, fighter, interdiction and attack versions of the same airframe. Some of those aircraft are still being flown in foreign services. Same goes with A-4 Skyhawk.

Not quite designed as “one size fits all”.

The F-4 and A-4 were designed specifically as Navy carrier aircraft. It just ended up that they were such good solid all-round aircraft built for the stresses of Navy use that the other forces liked them. :^)

The F-4 Phantom - Proof that with a big enough engine you can make a barn door (actually the whole barn) fly... ;)
