Lockheed P-2 Neptune (P2V) — Flight Manuals, NATOPS & Technical Documentation Collection

The P-2 Neptune is a legendary twin-engine maritime patrol and anti-submarine warfare (ASW) aircraft. First flying in May 1945, its engineering documents highlight a highly versatile airframe that evolved from purely piston-driven propulsion into a unique mixed-powerhouse aircraft — one of the most capable sub-hunters ever to fly the long ocean watches of the Cold War.

7. Illustrated Parts Breakdown — Navy Model P-2E and SP-2E Aircraft
Reference: AN 01-75EDA-4 | (Date per cover scan)
Published under authority of the Secretary of the Air Force and the Chief of the Bureau of Aeronautics.
Covers the P-2E (P2V-5) and SP-2E (SP2V-5) variants with full illustrated parts breakdown for airframe, systems, and components.

Aerodynamic & Airframe Design

• Configuration: Mid-wing layout optimized for endurance over open water with low aerodynamic drag to maximize operational range
• Varicam Tail: Variable camber horizontal stabilizer mechanism acting as a super-elevator trim tab system, reducing aerodynamic drag during long patrols as fuel burned off and centre of gravity shifted
• Tip Tanks: Centre-mounted teardrop wingtip fuel tanks introduced on the P2V-4/P2V-5 to improve high-aspect lateral stability and extend patrol endurance
• Drop Clear: Aerodynamic spacing engineered to ensure heavy wingtip tanks fell perfectly clear of the airframe if jettisoned in emergency

Powerplant

• Piston Power: Two Wright R-3350 Cyclone turbo-compound radial engines — R-3350-32WA delivering up to 3,700 bhp at 2,900 RPM at sea level
• Jet Augmentation: Two Westinghouse J34 turbojet pods (standard from P2V-5F onward, standard fit on P2V-7) — J34-WE-36 providing 3,400 lbf thrust each for heavy combat takeoffs and emergency climbs
• Hybrid Philosophy: The unique mixed powerplant managed the weight demands of heavy maritime patrol configurations while preserving the endurance of the radial engines for long ocean watches

Handling & Stability

• Centre of Gravity Management: The Varicam mechanism specifically compensated for massive CG shift dynamics as fuel burned off during 10-to-13-hour patrols
• Asymmetric Thrust: Stability assessments focus heavily on single-engine safety procedures, utilizing jet pod assistance to override dead-stick radial engine drag
• Pilot Praise: Crews consistently praised the Neptune's responsive control surfaces over long missions — a critical factor in crew endurance on extended ASW patrols

Performance Data — P-2H / P2V-7

Engineering Bulletins & Modifications

• MAD Stinger: Bulletins directed replacement of tail gun turrets with long Magnetic Anomaly Detection (MAD) booms for submarine detection
• Observation Nose: Nose gun assemblies systematically replaced with clear-glass nose observation enclosures for extended visual patrol capability
• Firefighting Conversion: Post-military bulletins outlined removal of primary bomb bays to integrate 2,000–3,000-gallon retardant tanks for aerial firefighting roles — giving the Neptune a remarkable second career as an air tanker
