The P2V Neptune series of aircraft was one of the more successful post-war designs for America, with service that spanned decades for a handful of American-friendly countries. The system was designed by Lockheed Corporation from the outset as a land-based maritime patrol and reconnaissance platform. The system proved so versatile and effective, that the base production model spawned a large series of variants in specialized roles.

The P2V Neptune was a twin engine high-wing monoplane design. Sporting various Wright-brand powerplants throughout its production run, the aircraft featured outstanding range. A most identifiable feature being the single large rudder on the empennage, though the overall gangly design of the nose was another memorable feature. The Neptune split time between the United States Navy and the United States Air Force, though it is widely remembered for its service with the Navy branch.

The Neptune got its start as early as 1944, where two XP2V-1 prototypes are delivered with 15 production P2V-1 models.
