The A-20 is a Soviet tier 4 light tank.

Underwent trials at the same time as the A-32, a prototype of the T-34. Both vehicles were adopted for service. However, the A-20 was never mass-produced.

The A-20 is a very fast tank with a high top speed, but suffers from poor maneuverability at high speed. As a "scout" tank, it is expected to face tanks up to Tier 8, which can be very challenging, to say the least.

The A-20 leads to the T-34.

Historical Info

Origin
A-20 during trials

Once it was realized that the BT tanks didn't have sufficient armor or armament, a new design was developed for a fast medium tank. In 1937, the Kharkov factory was ordered to design a new tank, and the design work started in November 1937. The chief designer was Mikhail Koshkin and his deputy, Alexsandr Morozov.

Design features The A-20 had sloping sides and a small angular turret with 25mm of armor. The tracks could be removed and could be run on just the wheels. The chassis itself was based on the BT-7M. The hull had a V-shaped glacis plate and was angled at 60°. The A-20's hull also overhung the tracks with the sides angled at 25°. In 1939, a 76.2 mm gun was installed and the vehicle was designated as the A-30. This was the same gun that was installed in the BT-7. There was an attempt to place a short barrelled 76.2 mm gun in the A-20's turret, but it just didn't work, as the turret ring couldn't absorb the recoil.

Prototype In May 1938, a wooden model of the A-20 was shown to the Defense Council of the Soviet People's Commissars (Soviet Narodnykh Komissarov, or SNAKE). Some didn't like the wheel / tracks feature carried over from the BT series, and Koshkin said it added weight that just wasn't necessary. The design had a 45 mm gun, which Koshkin said should be replaced by a 76.2 mm gun, as it was inadequate. Stalin was at this presentation and ordered that the Kharkov factory build not only a full-size prototype of the A-20, but also make the requested design changes and build a prototype that would be designated the A-30. In August 1938, the High War Council, let by the People's Commissar for Defense, K. J. Voroshilov, discussed the A-20 and T-32. Many on the Council disliked the T-32. In July 1939, the Kharkov Locomotive Factory had completed the prototypes for the A-20 and T-32. They were both then tested and it was decided to go with the T-32. On December 19, 1939, the People's Commissariat for Defense released the T-32 to the Red Army. It was soon designated the T-34.

In 1939, tests were conducted with the T-32 and A-20: the T-32 was selected as it had better fire power and armor.
