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.

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.
