The SU-122V was a blueprint project of the mid-1950s for a tank destroyer that used hull traverse for horizontal aiming. Hydropneumatic suspension with the possibility to tilt the hull back or forth was designed for the vehicle, which additionally increased the gun elevation and depression angles. The transmission compartment was located in the front part of the TD. The gun was not rigidly fixed—aiming occurred across two planes; however, the horizontal aiming sector was limited. The project existed only in blueprints.
