what is it?

The Lockheed P-2 Neptune (designated P2V by the United States Navy (USN) prior to September 1962) was a maritime patrol and antisubmarine warfare (ASW) aircraft. It was developed for the USN 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 few were converted and deployed as carrier-launched (using JATO assist), stop-gap nuclear bombers that would have to land on shore or ditch.

How to recognise it: 4 jet engines · retractable tricycle gear · 31.7 m wingspan

fun facts

  • First flew 81 years ago, in 1945.
  • Top speed is 4.5× a car on the Dutch motorway (130 km/h).
