12/31/2007. Remarks by Bill Zimmerman: "I was a non-flying member of Fleet Aircraft Service Squadron (FASRON) 102 in Hanger SP-1. The squadron was formed to help service our P5M patrol seaplane squadrons, VP-44 and VP-56. Just how FASRON got a P2V-5F is still a mystery to me.

The aircraft was one of 23 Model 426-42-06 P2V-5 built, powered by two 3,250 hp Wright R-3350-30WA Turbo-Compound twin row, 18-cylinder, supercharged, air-cooled, radial engines. Due to marginal power most P2V-5’s were converted to P2V-5F’s, the R-3350-30WA’s were upgraded to 3,500 hp R-3350-32W’s and two 3,250 lb (1,474 kg) s.t Westinghouse J34-WE-34 turbojets were slung from the wings. The type was redesignated P-2E in 1962.

Lockheed had preformed structural static testing on the various P2V models, however, full scale fatigue testing was not performed as it was not required by the US Navy at the time of manufacturing. The Japanese Maritime Self Defense Force (JMSDF) used the P2V-7 aircraft and the JMSDF performed a full scale fatigue test of a P2V-5 airframe modified to a -7 configuration with the assistance of the USN.

Therefore the BuNo. 124870 was shipped to Japan in 1966, and modified as much as possible to a P2V-7 configuration. From May 1968 to March 1969 the full scale fatigue test frame simulated 12,990 flight hours, providing valuable data for the aging P-2 fleet."
