Early on during the production T-55s were fitted with the TSh-2B-32P sight. Starting in 1970 T-55s were being armed at Uralwagonzavod with either a 12.7 mm DShK 1938/46 or KPVT loader's anti-aircraft heavy machine guns. These tanks were known as Model 1970, or sometimes T-55AM. KTD-1 or KTD-2 laser rangefinders and R-123 or R-123M radio sets were fitted to older tanks starting in 1974 (Model 1974).[144][148] At the same time efforts were made to modernize and prolong the life of the drive train.[144]

SU-122-54 (Ob'yekt 600) (Samokhodnaya Ustanovka) – Self-propelled 122 mm gun, based on the T-54A and sometimes known as IT-122. Between 1955 and 1957, 77 vehicles were built with minor differences between production lots (different commander's cupola etc.). The SU-122-54 had a modified chassis, with small spaces between the first, second and fourth pair of wheels and a large gap between the third, similar to the T-62's; and a superstructure, built into the hull, housing the 122 mm D-49 L/48.4 gun for which the vehicle carries 35 rounds. The secondary armament consisted of two KPVT heavy machine guns, one mounted as an anti-aircraft machine gun near the commander's hatch and the other mounted coaxially with the main gun. The vehicle carried 600 rounds for the machine guns. The main gun has a fume extractor positioned right behind the muzzle brake, some vehicles did not have the fume extractor. Other variations included a different commander's cupola.[42]
