M-43 8-inch Howitzer Motor Carriage

The M-43 Howitzer Motor Carriage mounted the M1 or M2 8-inch howitzer in the M17 mount. This is the identical carriage to the M-40 that mounts a 155mm gun. Prototypes were produced late in World War II, were standardized as the M43 in November 1945, and saw service in Korea.

The carriage was developed from the M4 Sherman tank chassis. In development, this vehicle was designated T89. In addition to its armament, it carred 16 rounds of 8-in. howitzer ammunition. It was fitted with a rear spade and a folding crew platform behind the gun.

The manufacturer was Pressed Steel Car Company of Pittsburgh, PA.
