Lockheed P2V-7B/SP-2H Neptune
The P2V-7, Lockheed Model 726, was the last version, built by Lockheed of the Lockheed Neptune.
In 1954 the first flight was made. It differed from the previous version by the more powerful Wright R-335-32W radial engines of 3,700 horsepower each, and by the two Westinghouse J-34 W-36 jet engines.
The AN/APS-20 radar radome was moved forward. The bomb bay was enlarged and could carry a load of 10,000 lbs.
Furthermore, the canopy was revised and the cockpit was placed higher and finally also the smaller tip tanks of the last P-2V-5 versions were used.

The dorsal turret was finally replaced by a window.
