Comparing: Churchill I vs. VK 30.01 (H) vs. Churchill III

The A22 prototype was built by Vauxhall Motors in the fall of 1940. The vehicle first entered mass production in the summer of 1941. Early modifications had no track fenders, a different fan, and a 3-inch howitzer in the hull. A total of 300 Churchill I tanks were manufactured.

An order for developing the vehicle was placed on September 9, 1939. Over the course of its development, Henschel engineers actively used elements of the D.W. II project. The first two prototypes were ready in March 1942; another two were built by October the same year. Hulls of the prototypes underwent trials at the plant proving ground. After the trials, two prototypes were converted into heavy tank destoyers. Six turrets manufactured by the Krupp company were placed at the Atlantic Wall.

A British tank supplied to the U.S.S.R. under Lend-Lease. The U.S.S.R. received a total of 301 vehicles, with some lost at sea during transport to Murmansk.
