Proposed Soviet Heavy Tanks, Spring 1941

The USSR was developing tons of heavy tanks before the start of the war, with very many variations on possible designs of the KV-4 and KV-5. The characteristics of the final designs are summarized in this table.

The T-44 is, of course, not the late-war medium tank, but the pre-war medium/heavy tank, more commonly known as the A-44. 

Eagle-eyed readers may detect some mystery in this table. Take a look at the KV-4 column. One gun, 90 tons, 170 mm of front armour, 35 kph top speed? This isn't Shashmurin's project, the one he claimed won the tender in his memoirs!
