The SP-2H, originally designated P2V-7, is the final production variant of the Lockheed P-2 Neptune, a long-serving maritime patrol and reconnaissance aircraft. This version, known for its dual power system, combined two piston engines (Wright R-3350) with two auxiliary jet engines (Westinghouse J34-WE-36) for increased takeoff performance and speed. The P2V-7 introduced design enhancements, including a bulged cockpit canopy and improved wingtip tanks, while maintaining its capability for anti-submarine warfare. It was foundational to Cold War operations and saw significant service, including surveillance missions during the Vietnam War.
Lockheed Martin, a global aerospace and defense leader, traces its history to the early 20th century. The aircraft’s direct predecessor, the Lockheed Aircraft Corporation, developed the P-2 Neptune in the mid-1940s as a replacement for older patrol bombers. The P2V-7 entered service in the late 1950s, representing a peak of piston-engine anti-submarine technology before the introduction of purely turboprop designs like the P-3 Orion. The P-2 Neptune series, built by Lockheed, proved its reliability worldwide and continued flying with various operators into the 1980s.
Access solutions are available for this aircraft to address detailed maintenance requirements. These products, such as platforms and stands, facilitate safe and efficient work on critical areas including the nose section, forward fuselage, landing gear, and the wing/engine pylon assemblies. Specialized equipment also supports inspection and servicing of the AFT fuselage and the tail section (empennage).
