Fifty years ago, NOAA’s newly acquired WP-3D Orion aircraft, N42RF, flew its very first mission into a tropical cyclone. On June 27, 1976, the aircraft took off from Acapulco, Mexico, to intercept Hurricane Bonny in the eastern Pacific.
The Department of Commerce purchased the aircraft the previous year to replace the aging DC-6 research planes that had been in service since 1960. The devastating impact of Hurricane Camille in 1969 drove the urgent need for a modernized fleet to better withstand storm conditions.
Because the Atlantic season was quiet and Bonny was a minimal, weak storm with winds just over 74 mph, it provided a relatively safe and accessible testing ground for the new aircraft. For six hours, the crew navigated the system, using nose radar, temperature probes and pressure sensors.
Half a century later, the NOAA P-3s remain integral to hurricane research and reconnaissance, improving forecast accuracy to save lives and protect property.
As the P-3 celebrates 50 years of service, original crew member Jim DuGranrut looks back on the aircraft’s legacy and shares what this milestone means to him.
