To resolve the problem about the anxiety about inadequacy of armor security within the currently greatly armored KV-1 Model 1941, it absolutely was chose to bring the armor safety linked to the turret around a depth to 75mm. As the convenience of creating such a thick armor dish ended up being lacking at that time, so an interim solution would be to use bolt on armor, 25 mm of level, bolt to the surface linked to the turret and some the rest linked to the hull. This type ended up being often referred to as KV-1s Ehkranami.
