Description

The Object 268 is a rank V soviet tank destroyer with a battle rating of 7.3. It was introduced in update Update 1.69 "Regia Aeronautica". The Object 268 is a self-propelled gun based on the T-10M heavy tank featuring a 152mm M-64 cannon.

General info

Survivability and armour

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?

If necessary use a visual template to indicate the most secure and weak zones of the armour.

The Object 268 is armed with a single 14.5mm KPVT heavy machine gun commanded by the commander. It is highly effective in dispatching lightly armoured vehicles and defending from air attacks. It can even potentially damage or destroy enemy gun barrels. However, this machine gun is loaded with 50 round belts, which only allows for a few short bursts punctuated with a lengthy reload.

Usage in battles

The Object 268 is an excellent single-direction brawler, as its frontal armour can withstand most kinetic shells at its BR, it is capable of locking down an entire street, which dissuades any enemy advances in the area. Although it is best used in urban maps as a brawler, it can also function as a mobile pillbox in rural maps, drawing enemy fire and covering a wide area of the map to deny enemy movements.

Pros and cons

Pros:

  • Excellent frontal protection, the armour is more than 250mm thick in most places and can deflect virtually any kinetic energy projectile at its BR with ease.
  • Single frontal weakspot is relatively small and easy to conceal with bushes.
  • Excellent firepower, with a fast-firing 152mm and a 14.5mm machine gun, which is perfect for dealing with light tanks and dissuading enemy air support.
  • Impressive mobility in a straight line.
  • All ammunition types remain effective at long ranges, solving an issue that persists with many Russian tanks at this BR.
  • Side armour of the casemate is an excellent 100mm. Which can afford you to engage targets from multiple directions without having to worry about exposing weaker side armour.
  • The original reload speed is retained with the loss of one loader.
  • Has access to a unlockable Rangefinder modification, increasing its already impressive performance at longer ranges.

Cons:

  • Large and boxy profile makes the Object 268 relatively easy to spot.
  • Unimpressive turning ability makes it difficult to deal with flanking enemies at closer ranges, and nearly impossible to counter targets directly behind the vehicle.
  • Large ammo racks on the sides and rear of the vehicle's casemate make flanking shots extremely lethal and usually unforgiving.
  • Firing the cannon kicks up a massive dust cloud, making the vehicle easy to spot when its firing from a concealed position.
  • The 14.5mm KPV machine gun cannot point directly to the vehicle's left side, as its traverse is blocked by the rangefinder and cupola.
  • Small weakspot next to the gun is a flat 187mm area, and is usually lethal if penetrated.

History

Development

The Object 268 self-propelled gun was one of the many derivative designs of the T-10 heavy tank. The concept began on 2 July 1952 at the Leningrad Kirov Plant on the order of the Council of Ministers USSR.[1] The Object 268 would follow in the same line of doctrine as had the earlier Soviet self-propelled guns of World War II, the SU-100, -122, and -152. This contrasted with the Western concept of a self-propelled gun being used as an artillery piece rather than the Soviet usage as a tank destroyer.[1] There had been earlier attempts at converting a heavy tank to a self-propelled gun, using the chassis of the IS-4 and IS-7, but those had not been fully developed and were cancelled. The IS-4 production was running too slowly and the IS-7 had been too complex to manufacture in large numbers.[2] The Leningrad Kirov Plant worked to produce an SPG on the T-10 chassis by combining it with the 152 mm M-48 cannon, which had high velocity and was much more powerful than earlier 152 mm cannons. Drawing work led to the Object 730 SPG which would be paired with the M-53 cannon, a parallel development to the M-48.[3]

The Object 730 SPG had five different variants drawn up with each one being unique. Version No.1 was a front mounted casemate design which would be developed into the Object 268. Version No.2 had a rear casemate with the main armament using a drum magazine at the rear of the fighting compartment and the engine at the front of the vehicle.[4] Version No.3 abandoned the casemate design and used a conventional turret with all ammunition being stored in the rear of the turret.[4] Version No.4 was a slightly modified No.2 with a lengthened hull, addition of a second loader (bringing the crew to five) and a new cupola with a rangefinder and machine gun.[5] Version No.5, likewise, was a reworked No.3 to also bring the crew to five and the addition of a 14.5 mm KPV machine gun, along with it using the same engine as would be used in the T-10M.[6] Versions No.4 and 5 were rejected due to being too drastic of changes to the base design, and it was decided to go with a slightly modified Version No.1 with the same engine as the T-10M.[7]

Final Design and Prototype

The final design for the Object 268 was presented to the committee in June 1953 using technical drawings and a scale model, which was approved on 25 August by A.I. Radzievsky.[7] This would be armed with the 152 mm M-64 cannon along with a 14.5 mm KPVT machine gun on the roof of the casemate, along with a stereoscopic rangefinder. While the crew was kept at five (having two loaders), it was intended to have a crew of four as soon as an automated loading mechanism could be made for the M-64 cannon.[7] The main armament was being slowly developed due to being lower priority than 122 mm development, but the M-64 was created by taking the M-53 cannon and slightly shortening it while still maintaining a muzzle velocity of 750 m/s.[8] The final drawings for the Object 268 were finalized in June 1954, reviewed in August and construction on prototypes had begun in March 1955.

Work continued on the M-64 cannon, with the prototype being completed in December 1955 and one being sent to Leningrad for installation into the Object 268 in February 1956. The prototype Object 268 was finally completed in March 1956 and was also still modified from the final drawings, as it was decided to use flat steel plates for the roof and rear of the casemate rather than the originally planned rounded plates as well modifications to allow the main armament to be installed and removed.[9]

Completed Vehicle and Cancellation

The completed Object 268 prototype was armed with the 152.4 mm M-64 cannon, built at the Leningrad plant, using the TSh-2A "Sharik" sight for direct fire and the ZiS-3 panoramic sight.[10] A TKD-09 stereoscopic rangefinder was mounted on the roof of the casemate along with a 14.5 mm KPVT heavy machine gun in a rotating ring above the gunner's hatch.[10] Full ammunition load was 35 rounds, with AP and HE-FRAG being available. The range at which a target could be engaged in direct fire was 900 meters with a maximum indirect fire range of 13,000 meters.[10] The hull of the Object 268 was 120 mm thick of RHA and the casemate was 187 mm. The engine used was the V-12-6 generating 750 HP, as well as using the same transmission as the T-10. Weight of the tank was 50 tonnes with a maximum speed of 48 km/h.

The Object 268 was ultimately cancelled, largely due to internal problems associated with the development of Soviet tanks. By the time the prototype was completed and trials had finished it was approaching the end of 1957 and even further development had been done. These designs had specifications and characteristics that were more advanced that the Object 268 and would have been so well protected that the M-64 cannon would have difficulty in taking them out.[11] It was expected that the Western tank development would also be able to defend against the Object 268, and the T-10 heavy tank had already begun production which could have caused issues if tank plants were made to manufacture a different version at the same time. In addition, a major shift in Soviet doctrine to incorporate more usage of anti-tank guided missiles, which had just been created in the Soviet Union in 1956.[11] The Object 268 was not accepted for mass production and further development of the Object 268 was halted, with only the single prototype having been made. It remains in the Kubinka tank polygon and museum.
