ww2dbaseIn 1937, the Glenn L. Martin Company designed a new twin-engined flying boat meant to compliment the Consolidated PBY Catalina aircraft already in military service. On 30 Jun 1937, Martin received an order for a single prototype, followed by an order for an additional 21 examples on 28 Dec 1937. The prototype, XPBM-1, took flight on 18 Feb 1939. To defend itself, the design called for five gun turrets; meanwhile, the bomb bay was large enough for 1,800-kilograms of bombs. They first entered service on 1 Sep 1940, with the US Navy Patrol Squadron VP-55. They operated in neutrality patrol roles prior to the American entrance to the war. After the war began for the United States, they mainly operated in anti-submarine roles, sinking their first German submarine, U-158, on 30 Jun 1942. Throughout the course of the war, they were credited with ten German submarine sinkings. They were also used in the Pacific War, operating in forward areas such as Saipan and Okinawa after seaplane bases were secured. In additional to the US Navy, the US Coast Guard also operated PBM Mariner aircraft. In early 1943, the USCG acquired 27 PBM-3 aircraft. The number increased by 41 PBM-5 aircraft in late 1944, followed by another delivery in early 1945. They operated in patrols off the US coast during the war, and remained in service until 1958. After WW2, US Navy continued to operate PBM Mariner aircraft for patrol missions, including during the Korean War. The last US Navy PBM was taken out of service in Jul 1956.

ww2dbase32 PBM Mariner aircraft were leased to the British Royal Air Force, but they were not deployed operationally; some of them were later returned to the US Navy. 12 PBM-3R aircraft were transferred to the Royal Australian Air Force during the war; they served in transport roles during WW2.

ww2dbaseAfter the war, in late 1955, 17 PBM-5A Mariner aircraft were sold to the Royal Netherlands Navy; they were deployed to New Guinea. The Dutch examples remained in service until Dec 1959.

ww2dbaseDuring the production life of the design, a total of 1,366 PBM Mariner aircraft were built.

PBM Mariner Timeline

16 Sep 1941 5 PBM Mariner aircraft and 1 PBY Catalina aircraft received radar to help these American aircraft conduct their neutrality patrols.
1 Oct 1944 60 miles west of Palau, US Navy PBM-3D Mariner from Patrol-Bombing Squadron VPB-16 flown by Lt Floyd Wardlow launched a Mark 24 FIDO acoustic homing torpedo on the diving Japanese submarine I-177. The submarine was damaged severely and was sunk 2 days later in a Hedgehog attack from destroyer escort USS Samuel S. Miles.
21 Jan 1945 West of Ulithi, Japanese submarine I-48 with its deck loaded with four Kaitens was spotted on the surface by US Navy Lt Frank Yourek flying a PBM-3D Mariner. The patrol aircraft released two depth charges and one Mark 24 FIDO acoustic homing torpedo that severely damaged I-48. Two days later north of Yap, destroyer escorts USS Conklin and Corbesier made a Hedgehog attack on I-48 and the submarine was sunk with all 118 hands plus the four Kaiten pilots.

My father flew PBM's in the Solomon Islands in WWII. Was awarded several DFC's for bravery; we never knew the exact number. Neither the Army Air Corp or Navy recorded these medals. We only know the kind of work these pilots did took a huge toll on the squadrons. They were the "dustoff" pilots of WWII.

I flew in the PBM -5A, tn 5444 at the Coast Guard Air Station in Brooklyn, NY in the mid 50's. Saw them phased out sometime during that period.

My father was a tail gunner on a PBM in the Pacific theatre during WW2. He was flying missions over Saipan and Okinawa. He was also at Tokyo. Like Skip I had to pry information out of him. He did say they did bombing, surveillance and search and rescue. At Okaniwa and Japan after the surrender he said they flew patrols along the rivers looking for Japanese who had not surrendered.

My Uncle Fred served in the US Navy during WWII and after the war was involved in the collision of two PBM's near Corpus Christie TX in November, 1945. While he never talked about it, he was awarded a decoration for saving crew members in the resulting fiery crash, according to my grandmother. He had previously flown as an enlisted observer in SBD's. This he told me as I was building a Monogram model of a Dauntless in the early 1960's.

My dad was a PBM pilot operating off the East Coast during WWII. He was part of VP-215 also known as VPB-215. His name was LT(jg) Robert "Bob" Smith. If anyone out there knows of a relative who flew with my dad I would love to hear from you. I have pictures of my dad and his crew in front of their PBM but I don't know any of their names. Hope to hear from you.

I'm trying to find information on Patrol Bombing Squadron VPB-152, specifically about a PBM crew which flew a Saipan to Leyte Gulf route and participated in the 8/2/45 rescue of USS Indianapolis survivors by dropping rafts and supplies at approximately the same time as PB-538 Pilot Gwinn first spotted the wreckage. Call number for the flight on that day is K9244 but the pilot is listed as unknown in the record of flight operations. I am trying to track down the crew roster so I can learn more about how they assisted the rescue efforts - the PBM doesn't show up in many accounts of the rescue and they haven't been given much credit. Please email me at jimnrainey@yahoo.com - if you can provide any information or point me in the right direction it is much appreciated.
