The 122 mm howitzer M1938 was a field artillery piece used by the Soviet Union during World War II. It was also employed by the North Korean Army during the Korean armed conflict and by the North Vietnamese Army in the Vietnam War. It was massively produced by the Soviet Union State-run Motovilikha factories between 1939 and 1955, with over 19,000 pieces built. It was used to develop the Su-122 self-propelled artillery.
The 122 mm howitzer M1938 was designed by Fyodor Petrov as a replacement for the 122-mm M1909 gun, which had been fielded during World War I. It is a reliable and practical design, easy to carry around as it was towed to the front line by truck. Fitted with a small, steel-plate shield, the howitzer was mounted on a two-wheeled split-trail carriage and employed a hydro-pneumatic recoil system. It fired either high explosive or fragmentation shells. The howitzer barrel liner was made of high-quality steel made to withstand wear.
