The McDonnell Douglas A-4G Skyhawk was a variant of the Douglas A-4 Skyhawk attack aircraft developed for the Royal Australian Navy (RAN). The model was based on the A-4F variant of the Skyhawk, and was fitted with slightly different avionics as well as the capacity to operate AIM-9 Sidewinder air-to-air missiles. The RAN received ten A-4Gs in 1967 and another ten in 1971, and operated the type from 1967 to 1984.
