F-4E, Royal Australian Air Force, 2 OCU, 3 Squadron, 75 Squadron, 76 Squadron, 77 Squadron
A fictional skin based on an adaptation 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) depicted here: https://www.defesaaereanaval.com.br/aviacao/plastimodelismo-af-1-com-pintura-comemorativa-dos-15-anos .
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.
