Martin PBM mariner

Hey folks, how about this seaplane for our virtual skies



Quote
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 Consolidated PBY Catalina in service. A total of 1,366 were built, with the first example flying on 18 February 1939 and the type entering service in September 1940

Quote
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 Japan's attack on Pearl Harbor, PBMs were used on anti-submarine patrols, sinking their first German U-boat, U-158 on 30 June 1942. PBMs were responsible, wholly or in part, for sinking a total of 10 U-boats during World War II. PBMs were also heavily used in the Pacific War, 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 U.S. 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 Marlin and the HU-16 Albatross in the mid-1950s.

PBMs continued in service with the U.S. 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 12 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 with retractable landing gear. The engines were 2,100 hp (1,600 kW) Pratt & Whitney R-2800-34. After a series of crashes, the Dutch withdrew their remaining aircraft from use in December 1959.

+1!  I love me some seaplanes... There's just something sexy about them... I guess maybe because you can stumble across some remote island and find a group of topless natives worshipping you and your airplane?  LOL!

Note:  While the early PBM's had retractable wing floats... And the newer PBM's had retractable amphibious landing gear.... The most widely used PBM in WWII was the PBM-5.... Which had neither... Making this a pretty straight forward airplane.... The only animation/coding it would need besides basic flight controls would be the two bomb-bays in the wing nacelles.

Sadly no, taken from Wikipedia

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

Awesome request!! This would be to the PBY as the SB2C Helldiver is to the SBD Dauntless. Faster, heavier bomb load and much cooler looking!!  ;D
