Lockheed P-2 Neptune / P2V
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.
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.
