Comparing: Covenanter vs. A-20 vs. T-50

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.

Developed in October 1940. The design presented by Plant 174 was submitted for consideration. After successful trials in February and March 1941 the vehicle entered service.
