| The US Navy made several attempts to gain the benefit of high over-target performance combined with long range by introducing mixed powerplant. The Martin Model 219 patrol bomber represented one of the results of such a specification, two XP4M-1 prototypes being ordered on 6 July 1944. The first was flown on 20 September 1946 as a cantilever shoulder-wing monoplane with retractable tricycle landing gear. Its powerplant comprised two 2218kW Pratt & Whitney R-4360-4 Wasp Major radial engines, but each nacelle also incorporated a 17,350kg thrust Allison J33-A-17 turbojet. After a protracted development programme 19 P4M-1 production aircraft were built, the first being delivered to US Navy Squadron VP-21 on 28 June 1950, and all served with this unit. Most of them were converted into P4M-1Q Elint aircraft, one being shot down.

| Jim Price, e-mail, 19.12.2014 05:54 I was in VQ-1 from 59-61. I worked in the ECM office and flew on many of the missions. I remember many of them. The WV-2's we started flying after the P-4's were bigger and roomier. Many years ago. reply | | Roy Wolfe, e-mail, 24.10.2014 20:03 Interested in contacting Mark Baker Jr. Flew with his dad during Port Lyautey deployment.roywolfe1322@comcast.net reply | | Willis E.Vanderberg, e-mail, 08.01.2014 21:13 The squadron in Port Lyautey was a VP not a VR.My error. reply | | Willis E. Vanderberg, e-mail, 08.01.2014 21:07 I was stationed in Port Lyautey French Morocco in 53-54 VR-24 was flying this type of aircraft.I was a member of the crash crew when one P4M landed with the gear up and smashed the radar dome all to pieces.Because of the J-33 in the Nacelles the landing gear was a long legged affair that folded outboard up aginst the wing bottom. We raised the old girl with a bunch of life rafts and lowered the gear. reply | |
| | John Ivory, e-mail, 23.10.2013 22:35 Looking for people who knew my Father JOHN E.IVORY. He flew out of Sangley Point and was a bow gunner on the P-4M's. I believe he was NAS Whiby Island as well, have a class or squadron photo with a P4M as the backdrop. reply | | Patricia Hampton Kinzie, e-mail, 07.09.2013 04:25 Do anyone have any information for me to include in my father's memoirs about the air crash on 19 Jan 1960 near Adana, Turkey? My father, LtCmdr Warren Jack Hampton, was co-pilot and died that day. I am gathering information for a family history. I don't understand the nature of the radar failure? reply |
| Jim Edixon, e-mail, 26.08.2013 04:18 Pilot - Flew with Hap Sweeten 1953 -1955. Flew 124362
when the left engine tore off - not something you would
care to have happen.Was flying '62 when it was attacked by
Migs April 1955.Had 124365 blow the right engine at 100 feet on take-off.
The P4M would climb 4000 ft /min at max gross weight on
take-off.
I enjoyed flying DC-9s and 727s later but the P4M remained
closest to my heart. reply | | stephen fontenot, e-mail, 17.06.2013 04:20 my dad J.Y. Fontenot left me a beltbuckle with 1952 P4M sangley point on it he talked about the plane and the phillipines quite a bit over the years. would love to hear from anyone who might have known him reply | | Norm Anderson, e-mail, 17.01.2013 22:54 I was in VQ-2 from 1957-1961 and flew as radar operator in the P4M-1Q many times. I was at Incirlic Air Base in Turkey the night one of our P4Ms flew into the side of a mountain on the way in from Spain. All 16 crewmen were killed including my best friend. Toward the end of the time we had them there were a lot of problems, fires, engines going out and were finally replaced with A3D and WV. The plane was fun to fly in, especially with a hotrod pilot. reply |

Hi Patricia. Did you ever find any further information about your fathers crash? I am researching this awful crash and trying to find a photograph of another serviceman also tragically killed on board that awful fateful day. His name is Marvin Radtke.
Thanks for any information anyone who reads this might have.
