2018年6月6日 · The A-20 tank has significant advantages over the existing BT tanks due to its engine, usage, and combat characteristics. Factory #183 must produce a pilot batch of 15 units by January 1st, 1940. Before then, correct all defects discovered during trials and reinforce the front plate to 25 mm and the front part of the floor to 15 mm.

On this day, the A-20 tank went to its first trial run, immediately after it was assembled and "scrolled" on the stand. During the trial run, the newly “born” car passed around the plant on...

The A-20 is a Soviet tier 5 light tank. Development of the A-20 tank started at Kharkov Factory No. 138 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.
