The Su-122 was an assault gun which used the hull of the T-34 tank and was the result of an April 1942 specification for assault guns aimed with guns of 122mm caliber or higher. The Su-122 was designed by the Uralsky Machine Building factory (UZTM). The first production SU-122s were built at the end of 1942, with a total of 25 vehicles being built.
The Su-122 did reasonably well in combat against the Wehrmacht, although the high explosive antitank (HEAT) round developed for its gun didn't perform up to expectations. Production continued from 1942 until the summer of 1944, with a total of roughly 1,150 vehicles built. Eventually, the Su-152 replaced most of the Su-122s still in service. Sold Out!
