A fictional skin based on a blend of the Gull Grey/Insignia White hi-vis of the Royal Australian Navy VC-724 Squadron, and the US Navy of the 1970s, but with the hawk's head from the Brazilian Navy's AF-1 (A-4KU Skyhawk) and darker grey of the aircraft depicted here:

Totally Fictional and blatantly transposing the markings of one aircraft onto a totally unrelated one for no reason other than I think they go together nicely.
