The P-3 Orion Research Group is a cooperation of Jaap Dubbeldam and Marco P.J. Borst. We both used to be "aircraftspotters" at the former RNLNAS Valkenburg in The Netherlands. Jaap's P-3 archives go back to the early seventies. Marco started to collect P-3 information in 1981 when the Royal Netherlands Navy received its first P-3C Orions. We started to cooperate as the "P-3 Orion Research Group" in January 1990 and today we consider ourselves as the world's leading experts on the Lockheed Martin P-3 Orion.
Since March 1990, we have published an "Orion News" section in the two-monthly magazine "Centerline" of the "Valkenburg Aircraft Spotters Association". In this news section we publish details on aircraft transfers to other squadrons and general news items on P-3 Orions around the world. We are also contributors to other magazines like “Scramble”.
Our first major project was the compilation of a booklet on the P-3 Orion which was published in February 1996. Marco P.J. Borst has also written numerous articles concerning P-3 Orion squadrons and their operations for international magazines like the former "Airborne LOG" (published by Lockheed Martin), "Maritime Patrol Aviation" (published by VP International), and "Air International".
The P-3 Orion Research Group (PORG) has published its second "P-3 Orion" booklet - which is an all-English version this time - in March 2001. This booklet features the same main chapters as the 1996 version (see our P-3 Orion Books section) but each chapter has been brought up-to-date. More information on this publication can be found in our P-3 Orion books section.
