Excerpted from Wings at the Ready - 75 Years of the Naval Air Reserve.
Naval Air Station North Island, one of the navy's earliest aviation bases, hosted the arrival of a large reserve contingent in January 1970, when Naval Air Reserve Detachment North Island, (NARDET) was established to support VP-63L3 and other units moving from Los Alamitos. Like Pt. Mugu, NAS North Island was destined to develop into a major reserve training activity as aviation programs relocated following the transfer of the Los Alamitos base to the Air National Guard.
In the summer of 1970, the NARDET was designated Naval Air Reserve Training Unit (NARTU), North Island, and then became Naval Air Reserve Unit, (NARU) in December1972. The Command was designated NAVAIRES, San Diego in April 1983.
Winthrop A Jackson and the P2V-7 (P-2H) record cards for the aircraft of North Island agree that the designation of the North Island Neptune training unit was NARTD (Naval Air Reserve Training Detachment) from January 1970 to mid summer 1970. Winthrop has kindly supplied me with his recollection of tail and side numbers for the P-2s. These come both from photographs (movie stills) and his logbook. He also supplied me with flight schedules from five seperate dates, showing BuNos together with tail codes and side nos of the aircraft flying on those dates.
All of the BuNos agree with the individual aircraft record card data of the P-2Hs. I don't have that data for the earlier P-2s yet.
