The story of Martin AM Mauler

Martin AM Mauler was designed in response to the needs of the US Navy during the critical mid-war period of World War II. It appeared in competition with three other designs proposed by Curtiss, Douglas and Kaiser-Fleetwings. At this point, the U.S. Navy required that the carrier-based single-seat, single-engine monoplane should have a dual role in its inventory to accept and surpass the then single-role dive bomber and torpedo bomber capabilities.

The aircraft will be powered by a Pratt & Whitney R-4360 Wasp Major radial piston engine. The U.S. Navy ordered two prototypes from the Glenn L. Martin Company on May 31, 1944, under development designation "XBTM-1".

On August 26, 1944, the prototype XBTM-1 completed its maiden flight. A second prototype was approved and additional flight tests were completed. This is followed by approximately 16 pre-production examples for formal evaluation and elimination of identified design flaws. However, the war in Europe ended in May 1945 with the Soviet occupation of Berlin and the surrender of Japan in August after dropping two atomic bombs, officially ending World War II. What was once a large purchase order of 785 aircraft was decisively reduced to a more manageable production prototype of 132 aircraft.

In 1946, the BTM-1 was renamed the AM-1 (commonly referred to as "Martin AM Mauler"). However, the AM-1 proved to be lucky, as many American aircraft programs were completely scrapped after the conflict ended.

Hindered by the end of the war and its inherently beneficial war industry, Mauler continued to fight as best he could. By the end of the war, Douglas had begun work on a similar - albeit smaller - carrier-based attack aircraft, the first flight of which was recorded on March 18, 1945.

Introduced as early as 1946 as the A-1 Skyraider, the aircraft posed a direct threat to Mauler's future. The U.S. Navy will end up buying about 3,180 Skyraiders compared to the much smaller number of Maulers.

Mauler had a rather limited lifespan due to threats to its expansion, and was eventually surpassed by Skyraider itself. Originally, Maulers served in the U.S. Atlantic Fleet before being downgraded to land-based service.

From there, the last Mauler units remained active in front-line service until 1950 when they were finally decommissioned in 1953, with 151 prototypes completed. Seventeen newly constructed units were commissioned as two radar countermeasures platforms (Electronic Countermeasures - ECM), alternatively designated "AM-1Q".

Martin unsuccessfully proposed to the U.S. Navy a carrier-based delivery (COD) version, the JR2M-1 Mercurythese would be transport aircraft dedicated to providing fresh supplies to the carrier at seaand has since taken over the dedicated role navy planes and helicopters.

In general, the Martin AM Mauler is used by US Navy squadrons VA-44, VA-45, VA84, VA-85, VA-174 and VC-4. The aircraft was later used by the reserve forces in the years when the vehicle was in decline.

The Mauler was never used in rage, even during the Korean War (1950-1953) when the A-1 Skyraider entered the arena of combat.

The original competing aircraft that met the requirements of the US Navy - the Curtis XBTC, Douglas XBT2D-1 and Kaiser-Fleet Wing XBTK-1 - differed in their respective service lives. XBTC produced only two prototypes before being scrapped, the XBT2D-1 became the legendary A-1 Skyraider of the Vietnam War, and the XBTK-1 failed after five prototypes.

By this standard, Martin Mauler's success behind the A-1 Skyraider is somewhat limited.
