Further development of KV-1, T-150 was more armoured and by few sources had a turret of the KV-220-2, which was in return a possible turret of KV-3. T-150 underwent trials and was reported to have been assigned to defense of Leningrad. The serial production never started, but served as bases for modifications of KV-1 with reinforced armor.

T-150 was a proposed improved tank based on KV-1. With a higher armor, the weight increased up to 50 tonnes. The turrets should have been slightly modified KV-1 or a turret of KV-220-2. The armament was also 76mm gun. The sources claims T-150 fought in Leningrad, but other sources disapproves it.
