The A and B were externally identical for all intents and purposes.
The D is and Air Force version and differs quite a bit
The E is a navalised version of the USAF. It differs visually from the A/B mainly in the cannon installation; one on either side of the intake on the A/B verse one Gatling gun on the E. Fujimi makes the best A/B in 1/72 and IIRC Superscale made decals for VA-155. As for 1/48 I'm not sure, Hasegawa makes a great E and Monogran used to have a dog of an A/B. HTH
