The Object 268 was a casemate design, with a heavily armoured superstructure and powerful 152mm gun. The casemate reached 187mm of rolled homogenous armour (RHA) at the front, with 120mm RHA on the frontal hull. The sides of the casemate were 100mm thick, and the rear was 50-60mm thick. By the end of the design process, the vehicle weighed just under 50 tons, and coupled with the powerful V-12-6 engine, could reach a maximum speed of 48km/h.
