Hello

 

History:
The project IS-6 (object 253) was developed on the pilot plant number 100 in Chelyabinsk in the first half of 1944th The main feature of this war machine was the use of their electro-mechanical transmission
In accordance with the decision of the GKO Order of People's Commissar for Tank Industry on June 8, 1944 Uralmashzavod together with the serial number 100 was manufacturing drawings and making prototypes commissioned heavy tank IS-6 The basic design of the work was been completed by the number 100, a majority of which fell to the share of Uralmash Bauer, as release of working drawings produced here. Prototyping performed two factories with assembly and debugging tanks at the plant Uralmash.
 
In the fall of 1944 after the factory test tank IS-6 with a second set of spare parts and the body was sent to NIBTPoligon in Kubinka for comparative testing of new heavy tanks, tank factories.
Heavy tank IS-6 had a classic layout with the shape of the hull and turret, which is close to the IS-4.
122 mm tank gun D-30 of 30 rounds.On the roof of the tower was installed a heavy anti-air machine gun ammunition DSHK has 1,200 rounds and the 7.62 mm machine gun have 500 rounds. The 12.7 mm anti-aircraft gun was equipped with a red dot sight K8-T. The crew consists of commander, driver, gunner and loader
 
The engine B-12 750 hp housed in the tank. The electromechanical transmission were the main producers of the DC output of 385 kW 305A and a weight of 1740 kg and is coaxial with the motor. In one block from the main generator on a common shaft three-phase synchronous generator SG-1A was designed to the engine cooling fan drive motors and diesel, as well as the drive battery charging units
 
Chassis IS-6 with six and three support rollers are on board was like chassis of the IS-2.
The speed limit was 43 km / h. The mass of the tank was reduced to 51.5 tonnes.
Firepower of the IS-6 is no better than the tanks IS-2, IS-3 and IS-4 Its armor was better than the IS-2 and IS-3, but slightly worse than IS-4. Installation of electrical transmission and facilitates the management of the tank should increase its maneuverability. However, this does not happen as a result of the large mass of the tank and electrical transmission, and also because of the low reliability of the latter.A IS-6 (object 252) has been tested with the mechanical transmissions of the IS-4. With the exception of the armor he had no advantages over other heavy tanks.

Yah but if the other nations will also get new hightier Tanks?

And where is the evidence of that? :P

Excuse me, but it is a bit of an overused saying: "Lets add everything to the Soviets, as the other countries, will maybe get something in the few years time". Ballance is important. And in the current state, this would break it (even more).

I support, because from what I read in Wikipedia, Object 253 was a worse IS-2 and Object 252 showed no significant advantages. Also, I'd rather have it as a premium than a gift vehicle.

Mhhh i dont think so look on the first picture the IS-6 hull ar better than the IS2,IS2Mod1944 hull and the slope is better 2

BR 7.0 or 7.7

Maybe as a limited edition tank, but honestly I don't see why the USSR would need this at the moment.  There's other vehicles that I would prefer to see added to their tree first (tank destroyers and assault guns in particular such as the ASU-85).

Well, it's as legitimate as T32 or MAUS, but there's one beautiful Russian heavy tank that I'd like to see in game much more than this one and it has very similar name... only the number is increased by 1 ;)s

 

The IS-7 with historical performance parameters would be so broken it wouldn't even be funny.  No thanks.

Well I don't think so... if you consider up to 400 mm penetration HEAT and APDS ammunition types we already have in game.

 

Let's see where do I begin?

 

60 km/h top speed with a 15.4 hp/t p/w ratio, a 130 mm autoloading gun, and armor that is immune to said gun all in one package?  Keep dreaming.  It's not gonna happen.

The grind to that HEATFS is long... And the cost of using it.....

 

Germany has 2 tanks that can use it,

US has 2 or 3.

Brits has none.

 

And the RNG/bounce....................

APDS on 105 mm canon on top medium tanks (Leopard 1, Centurion Mk. 10 and M60) has 277 mm of penetration at 1000 m, Conqueror has 354 mm of penetration with APDS...

 

BTW have you ever tried to kill a MAUS with a stock T-54 - any of those 3 models? With stock ammunition it's impossible to penetrate the Maus at distances over 800 m even if he doesn't know about you... and talking about grind to HEATFS... if you want to use get it in Russian tree you have 3 options... getting it on that last T-54 = grinding also previous 2; similarly with heavy tanks, where you have to get through IS-3 and IS-4 to get T-10M on which it's last modification. And finally SU-122-54, which is sitting on a BR of 7.7 and is in stock worse than any 6.3-7.0 TD.

+1  :good:, but as RuiGutter has said, the IS-6 is no better than that of the IS-2,3, and 4 (as stated in the following article excerpt):

 

"The maximum speed was 43 km / h (eighth in the manual transmission was blocked). The mass of the tank was reduced to 51.5 tons. Firepower tank IS-6 is not superior to the tanks IS-2, IP-3 and IS-4. Its armor protection was better than the JS-2 and IP-3, but slightly inferior to the JS-4. Installation of electric transmission and facilitates the management of the tank should enhance its maneuverability. However, this does not happen as a result of the large mass of the tank and zlektrotransmissii, and because of the low reliability of the latter. Regarding the option JS-6 with a manual transmission, except for the armor protection he did not have any advantages over other heavy tanks.

Anyway, here is some more content from the same source you can add to the OP:

 

History:

[spoiler]

The project of the heavy tank IS-6 (object 252, 253) has been developed at the pilot plant number 100 in Chelyabinsk in the first half of 1944. The main feature of this war machine was the use of her electro-mechanical transmission. 

In accordance with the decision of the GKO Order of the People's Commissar for Tank Industry on June 8, 1944 Uralmashzavod together with the plant number 100 was commissioned manufacturing drawings and production of prototypes heavy tank IS-6. The basic design work has been completed by the number 100, much of it fell on the share of Uralmash constructors, as release of working drawings produced here.

Heavy tank IS-6 had a classic layout with the shape of the hull and turret, which is close to the tank IS-4. 122 mm tank gun D-30 has been paired with a machine gun Goryunov. On the roof of the tower on the installed anti-aircraft machine gun turret DSHK. Tank Ammunition consisted of 30 rounds of separate loading 1,200 rounds of 7.62 mm ammunition and 500 12.7 mm anti-aircraft guns to. Sight Grand Slam - telescopic tank. 

The anti-aircraft gun was equipped with a red-dot sight K8-T. At the disposal of the commander, driver, gunner and loader had one viewing device MK-4. 

 

The engine V-12U capacity of 750 liters. from. housed in the aft tank. The electromechanical transmission were the main generator of the DC-305A power of 385 kW and a weight of 1740 kg, mounted coaxially with the engine. In one block from the main generator on a common shaft was three-phase synchronous generator SG-1A is designed to power the motor-fan cooling system, traction engines and diesel, as well as the drive battery charging units. Diesel were installed two small DC generator G-73, which fed generator excitation circuit DC-305A and SG-1A. 

Traction motors DC and DC-302A-302B reverse acting through airborne transmission connected to the drive wheels of the tank. Adjusting the thrust to make changes of the main generator. Operating current reaches 960 A, when driving on the highway it was 490 A, on the ground - 740 A. The voltage in the circuit up to 500 V. 

 

Chassis JS-6 with six and three supporting rollers are on board was like chassis of the JS-2. Suspension of the individual, torsion. 

The tank was installed the radio and F-10 intercom TPU 4bis F. was produced another example of the JS-6 (object 252) with a manual transmission type IS-3. Apparently, for its production using a second set of spare parts and hull of. The chassis were used road wheels of large diameter, and the rollers are absent. 

 

The maximum speed was 43 km / h (eighth in the manual transmission was blocked). The mass of the tank was reduced to 51.5 tons. Firepower tank IS-6 is not superior to the tanks IS-2, IP-3 and IS-4. Its armor protection was better than the JS-2 and IP-3, but slightly inferior to the JS-4. Installation of electric transmission and facilitates the management of the tank should enhance its maneuverability. However, this does not happen as a result of the large mass of the tank and zlektrotransmissii, and because of the low reliability of the latter. Regarding the option JS-6 with a manual transmission, except for the armor protection he did not have any advantages over other heavy tanks.

APDS on 105 mm canon on top medium tanks (Leopard 1, Centurion Mk. 10 and M60) has 277 mm of penetration at 1000 m, Conqueror has 354 mm of penetration with APDS...

 

BTW have you ever tried to kill a MAUS with a stock T-54 - any of those 3 models? With stock ammunition it's impossible to penetrate the Maus at distances over 800 m even if he doesn't know about you... and talking about grind to HEATFS... if you want to use get it in Russian tree you have 3 options... getting it on that last T-54 = grinding also previous 2; similarly with heavy tanks, where you have to get through IS-3 and IS-4 to get T-10M on which it's last modification. And finally SU-122-54, which is sitting on a BR of 7.7 and is in stock worse than any 6.3-7.0 TD.

I just started on the T54 1947, so i will find out soon. But the russian tanks can at least take some hits. At least in the lower BR.

 

The Leo just explodes.. But it will probably be better for me when i get to play it a while. It would probably do much better in RB/SB than in AB.

"Leopard" in red, over the tank, kind of says: Shot me, i'll break :Ps

 

But i have fun in the Leo no matter what.
