SU-85 / SU-122
The¾SU-122¾(from Samokhodnaya Ustanovka 122) was a Soviet self-propelled howitzer or assault gun used during World War II. ¾The number –122” in the designation represents the caliber of the main armament, the 122mm M-30S howitzer. ¾The chassis was that of the T-34.
Initial design work of a prototype U-35 assault gun, armed with the 122mm howitzer and built on the T-34 medium tank, was completed in August 1942. ¾The project emphasized minimizing modifications to the platform and the howitzer. ¾It used the same chassis, superstructure, engine and transmission and was armed with a new 122mm M-30S howitzer. ¾The U-35 entered service with the Red Army as the SU-35 (later renamed SU-122).
SU-122 production began in December 1942 with 27 vehicles built that month. ¾The original plan for production beyond that point was to produce 100 SU-122s each month. ¾Production continued until the summer of 1944, by which time a total of about 1,150 SU-122s had been built.
The¾SU-85¾(Samokhodnaya Ustanovka 85) was a Soviet casemate-style self-propelled gun used during World War II, based on the chassis of the T-34 medium tank. ¾Earlier Soviet self-propelled guns were meant to serve as either assault guns, such as the SU-122, or as tank destroyers; the SU-85 fell into the latter category. ¾The designation –85” signifies the bore of the vehicleês armament, the 85mm D-5S gun.
Based on the SU-122 chassis, SU-85 entered production in mid-1943, with the first vehicles reaching their units by August. ¾When the up-gunned T-34/85 medium tank entered mass production in the spring of 1944, there was no point in continuing production of a tank destroyer without superior firepower, so SU-85 production was stopped in late 1944 after 2,050 vehicles had been produced. ¾It was replaced on the production lines by the SU-100 tank destroyer, armed with the more powerful 100mm D-10S gun.
