The SU-122 was designed by the Uralsky Machine Building factory (UZTM). The first production SU-122s were built at the end of 1942, for a total of 25 vehicles.

Production continued from 1942 until the early autumn of 1943, for a total of roughly 1,150 SU-122s built.

Variants Towards the end of the production run, SU-122s were built with the same ball mantlet as the later SU-85s, but are easily recognizable by the thicker, shorter gun barrel of the 122-mm M-30 howitzer . The SU-122 had no variants that went into production, but there were several unsuccessful prototypes and minor variants. Various attempts were made to modernise and improve the SU-122, particularly in the area of simplification, to lower production costs. The first attempt to modernise the SU-122 resulted in the SU-122M, which was armed with the 122-mm U-11 howitzer instead of the M-30 howitzer of the SU-122 itself. To accommodate the new gun, the gun compartment was altered. Though this design showed some promise, trials showed numerous defects: the SU-122M was less reliable than the original SU-122, cost more and was overloaded. It was therefore not taken into production. The other attempt to create an improved SU-122 replacement was done by taking a SU-85SU-85 The SU-85 was a Soviet self-propelled antitank gun used during World War II, based on the chassis of the T-34 medium tank.... chassis and coupling it with the 122-mm D-6 howitzer, which was lighter and compacter than the U-11 howitzer. This again was not a success. Finally, there was a small series of SU-122s built on the chassis of the SU-100SU-100 Overview The SU-100 was a Soviet tank destroyer.... .
