M9 Gun Motor Carriage (3-inch Gun Motor Carriage T40)

History of the M9 Gun (3" T40 Gun)

As tensions increased between Imperial Japan and the United States during World War II (1939-1945), the U.S. military desperately needed a modern warfare system. This became evident in the anti-tank solutions sector, which led to the development of makeshift self-propelled vehicles using 3-inch anti-tank (AT) guns (basically the WWI-era M1918 anti-aircraft guns). M3 chassis and hull Lee/Grant medium tank.

The M3 was the primary American front-line vehicle in the war, and its useful chassis provided the basis for many vehicle forms of the new M4 Sherman line in 1942, as the war progressed and operations shifted.

The new tank destroyer became the 3" Gun Motor Carrier (GMC) T40, with the operational designation "M9". The vehicle retained the overall form and function of the M3 tank, but had a modified open octagonal body , which was added to match the length and height of the 3" gun. The gun also comes with its own mounting hardware, pitch/aileron controls, and recoil mechanism, but a lot depends on whether the entire vehicle is pointed in the direction of fire the driver sits on On the left front of the fuselage, the main gun assembly protrudes from the center of the front shroud. The M3 fuselage superstructure has a significantly lower profile on the T40, and the battlefield quality is good.

The landing gear retains the rear engine, front drive sprocket and rear roller .along each side of the hull are three two-wheeled bogies.

Baldwin Locomotive Works was commissioned to transform the M3 hull to the T40 design standard, work started in 1941. After the Japanese attack on Pearl Harbor in December 1941, the U.S. Army ordered about 1,000 locomotives of this type.

Despite the work the program lasted for most of early 1942, due to limited stocks of 3-inch guns and a shift in focus to the promising M10 Wolverine tank destroyer and T40/M9 projects, the program was launched in August A page that was shelved to history, that's all.

The M10 went on to become a classic American wartime tank, with more than 6,700 produced from 1942 to 1943.
