Lockheed P-2 Neptune / P2V

P2V-7 Neptune

The first US Navy contract for two XP2V-1 Neptune maritime-reconnaissance bombers was placed in April 1944. The first prototype flew in 1945. From then Lockheed received contracts for the P2V-1 to P2V-7 versions which were subsequently redesignated in the P-2 category.

Last versions in operational service were the P-2E (formerly P2V-5) which introduced the glazed nose, MAD tailboom, Julie/Jezebel ASW systems, etc, and later fitted with auxiliary underwing turbojets; SP-2E, as for the P-2E but with modernised equipment; P-2H, the first version to introduce auxiliary underwing turbojets and incorporating equipment and detail changes; and the SP-2H, as for the P-2H but with modernised equipment. These served with the Argentinian Navy (P-2H), Australian Air Force (SP-2H), Brazilian Air Force (P-2E), French Navy (P-2H), JMSDF (P-2H, and Kawasaki P-2J), Netherlands Navy (SP-2H), Portuguese Air Force (SP-2E) and the US Navy (SP-2H).
The P-2H Neptune was a variant used by the Maritime Patrol Command of the Canadian Armed Forces.

A small number of P2V-2 and P2V-7 Neptunes were in service with ski landing gear for operations in the Antarctic.


P2V-7 Neptune

Kawasaki developed from the Lockheed P-2H Neptune a new ASW and maritime patrol bomber which has the designation P-2J. First flown in July 1966, the P-2J -differed from the P-2H in having a lengthened fuselage, and 2,850 ehp General Electric T64-1HI-10 turboprops replacing original piston engines, plus underwing 3,085 lb st (1400 kgp) J3-1H1-7C turbojets.

Entering service with the JMSDF in 1969, the last of`82 production aircraft was delivered in 1979. Sixteen P2V-7 were supplied from the USA before Japanese production began. Armament of the P‑2J comprises up to 8,000 lb (3,628 kg) of bombs, depth charges, or tor­pedoes carried internally, and 16 5‑inch rockets underwing.

An approach in Vietnam was the monitoring of electronic sensors on the ground, the signals being received by the AP-2E Neptune.

Between 1945 and 1962, 1195 were manufactured.


Hawkins & Powers developed civil conversins of of C-130 and P2V-7 under TC A19NM, A30NM, and A34NM in the Restriced category as borate bombers for forest fire control.
