Soviet Heavy Tank Characteristics

The following table compares the prospective post-war heavy tanks of the USSR (the T-34 is included for completeness' sake, but they seem to have merged the T-34 and T-34-85 into one tank). The table was approved fairly quickly after the war, since the IS-3 and IS-7 already have its index, but the IS-7 still has characteristics of the Object 257 rather than a later model, and the IS-4 is still referred to as Object 701.

  1. God, the IS-7 was a beast! Why wasn't it mass produced?

    1. Too heavy and too expensive. The world was changing, and there was no more room for heavy tanks in it.

    2. Funny because the T-10 was 3 tonnes lighter but didn't apppear to be has powerful has the IS-7. Guess they should've held the project a little while until they changed their mind? Another thing that bothers me, how would 90mm and 105mm APDS and HEAT perform against those late heavies? And, I think Zaloga said that in Think Tank 2012, did the IS-3 really have a hefty price and lot of mechanical issues?

    3. The IS-7 was reaching 70 tons by the time production was due to start, the new limit for heavy tanks was 50 tons.

      Also I don't know about the price of the IS-3, but the mechanical reliability is the same as the of the IS-2, from everything I've seen.
