3 Inch Gun M5 - Development and Production History

Development and Production History

In 1940, the US Army just started to receive its first antitank gun, the 37 mm Gun M3. While it fitted the request of the Infantry for light, easy to manhandle anti-tank weapon, Artillery and Ordnance foresaw a need for a more powerful gun. This led to a number of expedient designs, such as adaptations of the 75 mm M1897 or towed variants of the 75 mm M3.

Late in 1940 the Ordnance Corps started another project - an anti-tank gun based on the 3 inch anti-aircraft gun T9. The barrel of the T9 was combined with breech, recoil system and carriage, all adapted from the 105 mm howitzer M2. The pilot of the weapon, named 3 inch Gun T10, was ready by September 1941. Although the subsequent testing revealed minor problems, it was clear that the gun, eventually standardized as M5 on carriage M1, presented major performance improvement over existing designs.

Production began in December 1942. In November 1943 a slightly modified carriage was standardized as M6. In this carriage a flat shield borrowed from the 105 mm howitzer was replaced by a new sloped one. In January 1944 AGF requested to upgrade the guns built with the early carriage M1 to carriage M6; consequently most of the guns that reached the frontline had the M6 carriage.

Famous quotes containing the words development, production and/or history:

    If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.
    Arthur Miller (b. 1915)

    To expect to increase prices and then to maintain them at a higher level by means of a plan which must of necessity increase production while decreasing consumption is to fly in the face of an economic law as well established as any law of nature.
    Calvin Coolidge (1872–1933)

    It takes a great deal of history to produce a little literature.
    Henry James (1843–1916)
