Comparing: Tiger II vs. KV-5

The most heavily armored tank carrying the most powerful anti-tank gun. The vehicle's drawbacks included an overloaded suspension and engine-transmission group, as well as excessive general mass. When engaging enemy vehicles at long range, the Tiger II had an upper hand over any other vehicle in terms of the gun and armor protection. However, due to the excessive mass of the vehicle, relatively low durability of the engine and transmission, and small total number of vehicles built, the Tiger II did not have any significant impact on the course of war.

Development began in June 1941 at the Leningrad Kirov Plant and was completed by August, but plans were interrupted due to the complicated situation on the front. The KV-5 was to utilize some components of the KV-1. A new turret was designed, incorporating the 107-mm ZIS-6 gun. Two roadwheels and a single support roller were to be added on each side. A new 1,200 h.p. diesel engine was being developed for the vehicle, however it was not completed in time and was replaced with two V-2K engines.
