Comparing: Covenanter vs. A-20

A new cruiser tank that featured such innovations as an opposed-piston engine, front placement of cooling radiators, and the wide use of welding. The vehicle was ordered for production on April 17, 1939. A total of 1,771 tanks in four base variants were mass-produced. The Covenanter tanks were used mostly for training purposes in the U.K. from 1940 through 1943.

Development of the A-20 tank started at Kharkiv Factory No. 183 in December 1937. The project was a further development of the BT-7 tank and became a predecessor of the legendary T-34. Work on the vehicle was led by Mikhail Koshkin. On May 18, 1938, technical characteristics of the tank designated BT-20 were approved. Only a few experimental prototypes, with a wheeled caterpillar suspension, were built for training purposes.
