The Lockheed P-2 Neptune was a maritime patrol and anti-submarine warfare (ASW) aircraft.
It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion.
Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched, stop-gap nuclear bombers that would have to land on shore or ditch.
The type was successful in export, and saw service with several armed forces.
