History of creation and combat usage

Development

The success of the T-54 tank in the early 1950s had the vehicle chassis used in many different variants for different roles. The roles range out from a self-propelled anti-aircraft gun, armoured recovery vehicle, bridge-layers, mine-clearers, flamethrowers, armoured personnel carriers, fire-fighting vehicles, and a self-propelled gun. The self-proplled gun, known as "Object 600", was a vehicle based off the T-54A design and carried the 122 mm gun infamous on the IS heavy tank series. The vehicle was known as the SU-122-54, but it has sometimes also be referred to as the IT-122 as well. The chassis was modified for the vehicle, with the large gap present between the first and second road wheels moved to between the third and fourth. The superstructure, like traditional designs, was built onto the hull and held the 122 mm gun. Secondary armament consisted of two KPVT heavy machine guns on coaxial and pintle-mount for anti-aircraft purposes. The general design was developed and built between 1955 and 1957, with a total of 77 units made with minor differences between each batches. Some batches had a fume extractor on the gun, some didn't. The designs also have various commander cupola designs with each production batch.

Cancellation

Not much of the SU-122-54 was known as it was rarely seen in the 1950s and 1960s until its existence is known sometime in the 1970s due to the Red Square parades. The SU-122-54 never saw widespread production aside from the 77 units created, despite testing with a more powerful 122 mm M-62S gun in the design.
