In 1967, the Royal Australian Navy received the first of its 18 S-2E Tracker ASW aircraft. In 1976, 13 of these aircraft were written off or damaged in a deliberately lit fire in their hangar at the Nowra Naval Air Base in Australia in an act of sabotage. Those 13 aircraft were replaced with S-2G tracker aircraft purchased from the USN stocks in the United States. In 1980, the decision was taken to replace HMAS Melbourne with a new, larger carrier. In 1983, the decision was taken to update the S-2G to turbine engines, Pratt and Whitney PT-6 engines being chosen, to give the RAN an all turbine fleet, removing the necessity to carry two types of fuel onboard the carrier.

This is the Turbo Firetracker conversion kit to bring it up to a Turbo Tracker:
