洛克希德P-2海王星（1962年9月以前被美国海军指定为P2V）是一架海上巡逻和反潜战（ASW）飞机。它由洛克希德公司为美国海军开发，以取代洛克希德光伏-1文图拉和PV-2鱼叉，并依次被洛克希德P-3猎户座取代。海王星号被设计为陆基飞机，从未在航母上着陆，尽管少数飞机被改装并部署为航母发射的权宜之计核轰炸机，它们将不得不在陆地基地抛弃或回收。该类型在出口方面很成功，并与几支武装部队一起服役。

General Characteristics and Role
The Lockheed P2V Neptune was a cornerstone of Cold War maritime security, serving as the primary land-based anti-submarine warfare (ASW) and maritime patrol aircraft for the U.S. Navy before the arrival of the P-3 Orion. The P2V-5F variant represents a critical evolutionary step in the series, featuring a mixed-powerplant configuration to handle the increasing weight of advanced electronics and weapon systems. Designed for grueling, long-endurance missions, the Neptune was often referred to as the hunter in hunter-killer naval groups. Its ability to loiter for hours over vast oceans while monitoring for submerged threats made it an indispensable tool for global maritime reconnaissance.

| Entered Service | 1950 (P2V-5), 1953 (5F Modification) |
| 船员 | 7 to 9 (including pilots, navigators, and sensor operators) |
| 长度 | 27.8 m (91 ft 2 in) |

Powerplant and Mixed-Propulsion Performance
- Primary Engines: 2 x Wright R-3350-32W Duplex-Cyclone 18-cylinder radial piston engines, providing 3,250 hp to 3,700 hp each.
- Auxiliary Engines: 2 x Westinghouse J34-WE-34 turbojet engines mounted in underwing pods, providing 3,250 lbf (14.5 kN) thrust each.
- Fuel Synergy: To simplify logistics, the jet engines were modified to burn the same 115/145 Avgas as the piston engines, eliminating the need for a separate jet fuel system.
- Maximum Speed: Approx. 584 km/h (363 mph) with jets engaged.
- Search Endurance: Over 10 hours at economical cruise speeds using only the piston engines.
- Sensor Suite: Equipped with the AN/APS-20 surface-search radar in a belly radome and an AN/ASQ-8 Magnetic Anomaly Detector (MAD) in the distinctive stinger tail extension.
- Armament: Internal bomb bay for up to 8,000 lb of torpedoes, depth charges, or mines, plus underwing racks for 5-inch HVAR rockets.
Service History and Legacy
- Global Reach: Beyond the U.S. Navy, the P2V-5 was exported to numerous allies including Australia, Canada, the Netherlands, and Japan (where it was later license-built by Kawasaki).
- The Truculent Turtle: Early in the Neptune’s life, a modified P2V-1 set a world record by flying non-stop from Australia to Ohio—a distance of 11,235 miles—without refueling.
- Vietnam Combat: During the Vietnam War, Neptunes were utilized as gunships (AP-2E) and sensor-deployment platforms (OP-2E) for monitoring the Ho Chi Minh Trail.
- Cold War Sentinel: P2V crews were often the first to intercept and photograph Soviet warships and submarines during the height of the Cold War.
- Civilian Firefighter: After retirement from military service, many Neptunes were converted into highly effective air tankers for aerial firefighting, serving for decades dropping fire retardant across North America.
