Heavy tank IC-6

Heavy project tank IS-6 (object 252, 253) was developed at the pilot plant No. 100 in Chelyabinsk in the first half of 1944. The main feature of this combat vehicle was the use of an electromechanical transmission on it.


In accordance with the decision of the State Defense Committee, the order of the People's Commissar of the tank industry from 8 June 1944, Uralmashzavod, together with the plant No. 100, was entrusted with the production of drawings and the production of prototypes of the heavy tank EC-6. The main design work has already been completed by the plant number 100, a significant part of them fell to the share of the designers of Uralmash, since the production of working drawings was made here.


The production of prototypes was carried out by both plants with the assembly and debugging of tanks at Uralmashzavod. In the autumn of 1944, after factory testing, the IS-6 tank, together with the second set of parts and a spare hull, was sent to Kubinka for comparative testing of new heavy tanks made by tank factories.


The heavy tank EC-6 had a classic layout with the hull and turret shape close to the tank EC-4. The 122-mm D-30 tank gun was paired with the Goryunov machine gun. The DShK anti-aircraft machine gun was installed on the turret roof on the turret. The ammunition of the tank consisted of 30 shots of separate loading, 1200 cartridges of caliber 7,62 mm and 500 cartridges of caliber 12,7 mm for anti-aircraft machine gun. Scope TBSH - telescopic, tank.

Anti-aircraft machine gun supplied with collimator sight K8-T. At the disposal of the commander, the driver, the gunner and the loader there was one viewing device MK-4.


Engine B-12U power 750 l. with. housed in the aft of the tank. The electromechanical transmission included the main generator DK-305А with power 385 kW and weight 1740 kg, installed coaxially with the engine. In the same block with the main generator on a common shaft there was a synchronous generator of a three-phase current SG-1А, designed to power the motors and fans of the cooling system of traction engines and diesel, as well as to drive the sub-battery. Two small G-73 DC generators were mounted on the diesel engine, which fed the excitation circuits of the DC-305A and SG-1A generators.

The traction electric motors DK-302А and DK-302Б of reverse action were connected to the driving wheels of the tank via onboard transmissions. The thrust force was adjusted by changing the excitation of the main generator. The operating current reached 960 A, while driving on the highway it was 490 A, on the ground - 740 A. The voltage in the circuit reached 500 B.


The chassis of the EC-6 with six support and three supporting rollers on board was similar to the chassis of the EC-2. Individual suspension, torsion bar.

The tank was installed radio 10-P and intercom TPU-4bis F. Another sample of the tank EC-6 (252 object) with a mechanical transmission of the type EC-3 was made. Apparently, for its manufacture used the second set of parts and spare armored hull. In the running gear, large-diameter track rollers were used, and there were no supporting rollers.


The maximum speed was 43 km / h (the eighth gear in the gearbox was locked). The mass of the tank decreased to 51,5 tons. In terms of firepower, the EC-6 tank did not exceed the EC-2, EC-3 and EC-4 tanks. Its armor protection was better than the EC-2 and EC-3 tanks, but somewhat inferior to the EC-4. The installation of electric transmission facilitated the management of the tank and was supposed to contribute to the improvement of its maneuverability. However, this did not happen due to the large mass of the tank itself, and electric transmission, as well as due to the low reliability of the latter. With regard to the version of the tank EC-6 with a mechanical transmission, with the exception of armor protection, he did not have any advantages over other heavy tanks.

    51,5 tons is a very large weight, especially for the 40s ... These are problems with bridges and loading ... And if God forbid you slip down the hill and somersault or burrow in the swamp, then you’ll steam before pull it out and put the car on the tracks ...
    In this situation, and 41 tons of T-72 is not easy, but if there’s +10 tons, there’s dirt on the chest, and there’s neither a tractor nor a chain hoist, then ...

      The article is unacceptably short, it is not at all clear why the idea came to the ET. The fact is that the lack of protection of the IS tanks appeared almost immediately, in addition to improving this parameter on the serial machine, work began on the design of new MBTs. Two in the same weight they became class (IS-3; IS-4). If the first, thanks to revolutionary decisions, remained in the “class,” the second easily left it after breaking the 55t line. It should be noted that the more often the military met with the “tigers”, the more they wanted have your tank in the "class" d 70T and the decision to develop such a machine was made to them later became IC 7.No to significantly potyazhelevshy heavy tanks and long-term, super-heavy, needed a new TEU and if the engine is allowed to take off further 150-200l.s. with an “acceptable” loss of life, there was a problem with the transmission, the limit of the existing one was a machine weighing 50 tons. And it was simply impossible to produce more perfect, manufacturing helical, involute gears (more advanced transmissions) was possible on special machines, and after the evacuation the machine park was extremely poor and worn out. This was the main reason for turning to ET, not the only one (getting gentle traction characteristics, reporting intelligence that the Germans are working hard on ET) but the main one. However, the practice of OCD in 44g showed the impossibility of Issue of ET on a large scale (at that time), the presence of unresolved fundamental issues of electric movement, high specific gravity, low efficiency. Despite this, work on ET continued until the end of the 50s. Returning to the problem of the machine park, we note that the necessary replenishment / modernization was made in Lend-Lease framework during V.O.V.

    Many thanks to the author for the material presented. I had to hear about this project before, but without much specificity. The IS-6 is an interesting tank, its creation is a big step in the domestic tank building.

      Bullshit, not a tank. As I drove a T34 for money, I will. There is no particular choice IMHO, to crawl on a T34 or a left, or take a fifty-fifty Frenchman, the USSR is now at 8 lv with guns for 175 penetration there is nothing to do. And for the IS-3 fan and Caernavron, which I hadn’t downloaded before the top, but the cannon already delivers.

          Gamers understand this BETTER than the rest, besides we are talking about a computer toy, given that neither the T34 nor the IS-6 were produced, then it makes no sense to discuss real tanks of this brand.

              And this real life tells us that the T-34 medium tank was manufactured in the USSR, and the American T34 heavy tank remained a prototype not put into production, just like the IS-6.

          Understand at last: there’s a shaky roll, but the discussion of the experimental tank is of a rather original design, there is some kind of direction for the “thoughts” to fly in our discussion posts, and then there are posts that, when read, make a mess ...
          Then it turns out that these are game models ...
          How do you players think it’s generally tactful of you to get into the discussion of a real model and compare it with the parameters of the game model, especially if you use your slang in a conversation that is incomprehensible to others?

          What kind of reaction did you want? Answer yourself honestly.
          Glad God, do what you want and tell about your games, just warn that you are talking about GAMES, and not about REAL models. Just don't get confused. Isn't that complicated?
