The Lockheed P-2H Neptune was a land-based, maritime patrol and anti-submarine warfare aircraft. It was designed during WWII but never saw wartime service, the first flight of the type was on 15 May 1945 with deliveries to squadrons taking place from March 1947. It was produced in many variants for many different operators, including the Argentinian Naval Aviation wing who used their last two Neptunes during the Falklands War April - June 1982, which were instrumental in identifying and tracking the British destroyer HMS Sheffield, then directing attacks by Super Etendard aircraft which resulted in the sinking of HMS Sheffield.

The Neptune was unusual in that it had two standard radial engines, 2 Wright R-3350-32W Cyclone Turbo- compounds generating 3,700 hp / 2,759 kW) each; but it also had 2 × Westinghouse J34-WE-34 turbojet engines, delivering 3,400 lbf (15.1 kN) thrust each, providing boost power for fully-laden takeoffs and faster transit times to partol and loiter areas,
