Lockheed NEPTUNE

The Neptune was a medium range maritime reconnaissance aircraft originally design and equipped with reciprocating engines. In 1952, the Lockheed Aircraft Company developed an improved version of the Neptune known to the US Navy as the P2V-7 which satisfactorily met RCAF requirements for a medium range reconnaissance aircraft to partially replace the Lancaster in that role.

This improved variant was scheduled to come off the production line staring in 1954. In 1957, the decision was made to provide the aircraft with jet thrust augmentation by installing two Westinghouse jet engine pods. The additional thrust improved take-off, increased endurance by allowing higher weights of fuel and generally improved the overall performance of the aircraft.
