Designed to achieve exceptional flight range and duration Plane P2V can trace their ancestry to the work done by the company "Vega» (Vega) (a subsidiary of "Lockheed"), and in particular the designer Makshortom, the aircraft, comprising the high aspect ratio wing, and then the two new radial engine R-3350. Due to the fact that the company has focused its efforts on other priority structures, such as the P-38 and "Ventura", the prototype XP2V-1 «N'eptun» (Neptune) flew only in the last month of the Second World War.

In addition to the qualities mentioned above, the aircraft also had large Fowler flaps to provide takeoff and landing characteristics on short runways, a large weapons bay and two defensive turrets. As if in confirmation of the point about the range the third serial plane P2V-1 installed in October 1946 the world record of the range of flight 18 077 km (11 235 miles). The first of the 838 "Neptune" aircraft was delivered to the US Navy in March of 1947 and continued to be used to combat submarines in many Western countries for the 1960-s inclusive. Produced in seven different versions, "Neptune" has turned into a magnificent sea patrol aircraft, which was also manufactured in a piston modification by the company "Kawasaki" in Japan.

In addition to its use in the various naval forces around the world, the modified aircraft 0R-2E "Elinta» (Elint), aircraft electronic intelligence, and AP-2N "flying artillery battery" is also very successfully used the Air Force and the US Army in Vietnam. Today, about 40 aircraft SP-2E / H, completely removed from the military service, beneficial use in North America as firefighters.
