The Martin PBM Mariner was a patrol bomber flying boat of World War II and the early Cold War period. It was designed to complement the PBY Catalina in service. 1,366 were built, with the first example flying on February 18, 1939 and the type entering service in September 1940.

Design and development

In 1937, the Glenn L. Martin Company designed a new twin engined flying boat to succeed its earlier Martin P3M and supplement the Consolidated PBY, the Model 162. It received an order for a single prototype XPBM-1 on 30 June 1937. This was followed by an initial production order for 21 PBM-1 aircraft on 28 December 1937.

To test the PBM's layout, Martin built a ⅜ scale flying model, the Martin 162A Tadpole Clipper with a crew of one and powered by a single 120 hp (90 kW) Chevrolet engine, this flying in December 1937. The first genuine PBM, the XPBM-1, flew on 18 February 1939.

The aircraft was fitted with five gun turrets and bomb bays that were in the engine nacelles. The gull wing was of cantilever design, and featured clean aerodynamics with an unbraced twin tail. The PBM-1 was equipped with retractable wing landing floats that were hinged inboard, like the Catalina. The PBM-3 had fixed floats, and the fuselage was three feet longer than that of the PBM-1.

Operational history

The first PBM-1s entered service with Patrol Squadron FIFTY-FIVE (VP-55) of the United States Navy on 1 September 1940. Prior to the outbreak of World War II, PBMs were used (together with PBYs) to carry out Neutrality Patrols in the Atlantic, including operations from Iceland. Following the Japanese Attack on Pearl Harbor, PBMs were used on anti-submarine patrols, sinking their first German U-Boat, U-158 on 30 June 1942. In total, PBMs were responsible, wholly or in part, for sinking 10 U-Boats during World War II. PBMs were also heavily used in the Pacific, operating from bases at Saipan, Okinawa, Iwo Jima and the South-West Pacific.

The United States Coast Guard acquired 27 Martin PBM-3 aircraft during the first half of 1943. In late 1944, the service acquired 41 PBM-5 models and more were delivered in the latter half of 1945. Ten were still in service in 1955, although all were gone from the active Coast Guard inventory by 1958 when the last example was released from CGAS San Diego and returned to the US Navy. These flying boats became the backbone of the long-range aerial search and rescue efforts of the Coast Guard in the early post-war years until supplanted by the P5M the HU-16 Albatross in the mid-1950s.

PBMs continued in service with the US Navy following the end of World War II, flying long patrol missions during the Korean War. It continued in front-line use until replaced by its direct development, the P5M Marlin, with the last USN squadron equipped with the PBM, Patrol Squadron FIFTY (VP-50), retiring them in July 1956.

The British Royal Air Force acquired 32 Mariners, but they were not used operationally, with some returned to the United States Navy. A further twelve PBM-3Rs were transferred to the Royal Australian Air Force for transporting troops and cargo.

The Royal Netherlands Navy acquired 17 PBM-5A Mariners at the end of 1955 for service in Netherlands New Guinea. The PBM-5A was an amphibian plane with retractable landing gear. The engines were 2,100 hp (1,566 kW) Pratt & Whitney R-2800-34. After a series of crashes, the Dutch withdrew their remaining aircraft from use in December 1959.

Survivors

United States Navy PBM-5A (Bureau Number (BuNo) 122071) is the only surviving Mariner. It is on loan from the National Air & Space Museum at Washington D.C., and is on display at the Pima Air & Space Museum in Tucson, Arizona. Operated by the USN between 1948 and 1956, it is is painted in the marking of Transport Squadron 21 (VR-21) and coded RZ 051 of the early 1950s.

Although only one complete Mariner aircraft exists another aircraft (PBM-5 59172) lies upside down under Lake Washington. It crashed on 6 May 1949 and after a number unsuccesfull attempts to recover the wreck over the following decades it is now used as a training site for divers.

The Model 162A (registered NX19168), the piloted quarter scale test aircraft, is on display at the Baltimore Museum of Industry.

Accidents and incidents

United States Navy PBM-5 (BuNo 59225) based at Naval Air Station Banana River, Florida was destroyed in a mid-air explosion in December 1945 off the coast of Florida near the Bahamas while searching for the missing TBF Avengers of Flight 19 from Naval Air Station Fort Lauderdale, Florida.
A US Navy PBM-5 crashed on Thurston Island, Antarctica on December 30, 1946 while supporting Operation Highjump.
On November 30, 1944 a US Navy PBM-5 crashed into Mount Tamalpais in Northern California killing 8 Naval Aviators and Naval Aircrewmen. The plane had taken off from Naval Air Station Alameda and was part of a larger flight headed for Hawaii when it developed engine trouble shortly after take-off.
