Pros and cons

Pros:

  • Very powerful shells cause extreme damage once it penetrates, often resulting in one shot kills.
  • Heavily sloped armor from the front with very few weakspots
  • Good top speed for a tank destroyer
  • Above average mobility

Cons:

  • HEAT penetration is relatively weak

Modules and improvements

History of creation and combat usage

Development

Work began on a new self-propelled gun in the Soviet Union started in 1952. Headed by P.P. Isakov, the design process began in Leningrad at the Kirov factory by the Special Technological Design Bureau (OKTB). Drafts were drawn up as early as 25 April 1952 for a vehicle with the weight specification: weighing under 50 tons. The initial design had the vehicle built on top of an Object 730 chassis with the compartments arranged in ways such as a rear fighting compartment akin to the Ferdinand and a turreted version. By the Summer of 1952, the vehicle's design was being finalized into blue prints and on July 2nd, the Council of Ministers approved of the project, with the vehicle named as the Object 268.[1]

By January 1953, the vehicle variants were submitted after redesigns for approval, but the GBTU (Scientific-Technical Committee and Ministry of Transport and Heavy Machinebuilding) rejected the design with recommendation on improvements. The GBTU did approve of a separate project, which would a V-12-6 engine into the design. This redesign was sent in by June 1953, with an accompanying 1:10 model for viewing. Object 268 was approved Colonel-General A.I. Radzievskiy on August 25th, but work continued on the design, such as the gun which was still being designed at the time of acceptance. Work finally began in early 1954 and ended with the 152 mm M-64 gun, which was derived from the 152 mm M-53 but had a shorter barrel while retaining the shell velocity, reducing the overall barrel protrusion over the chassis. Though the gun was not fully built until December 1955 and not arrive at the Kirov factory until February 1956, the Object 268 design was finalized in March 1955.[1]

Production & cancellation

The same time Object 268 was finalized, plans for procurement of the prototypes were made. The first one was due by the first quarter of 1956, with two more before the end of the year. The delays with the gun as aforementioned meant these prototype plans were not met until Fall 1956.[1] Object 268 was produced by Factory 174 by Omsktransmash at city of Omsk.[2] The factory trials for Obect 268 began at its production and completed at Spring 1957, with the vehicle's performance being similar to that of the T-10 heavy tank. The vehicle was then sent to Kubinka, where gunnery trials showed the M-64 gun being superior to the World War II ML-20S gun on the ISU-152 in rate of fire, muzzle velocity, and range.[1]

Unfortunately, Object 268 fell out of favour in the fast-paced nature of the arms race. New tank developments in 1955 showed that the 152 mm M-64 gun would no longer be feasible as an anti-tank weapon. In an infantry-assault role, the ISU-152 in Soviet inventory were simply modernized to increase their service life, thus eliminating the need of a new vehicle design with a new gun. Then there was the development of the T-10 heavy tank, which would be produced in Kirov factory and Chelyabinsk Tractor Plant that would also be involved in producing the Object 268. Finally, there was the advent of the anti-tank missiles, which had started production in 1956. As such, Object 268 was cancelled after its tests and the two other prototypes initially ordered were also cancelled. It is known that Object 268 was the last Soviet heavy assault gun.[1]

The one prototype of the Object 268 is currently held at the Kubinka NIIBT museum.[2] The vehicle is still in running order.
