Soviet Union's T-38 light tank
T-38 light tank: |
Design
The T-38 was an improved design of the T-37, and was developed at Zavod Nr 37.1
The turret was moved to the left side and the driver on the right. Friction couplings were added to transmit power to the tracks. A new running gear suspension was installed that helped provide a vibration free driving.
The hull was redesigned which gave the T-38 a lower profile and less weight.1 Wider tracks for the T-38 also improved handling.1
Prototype
In the prototype a 20 mm SchWak gun was installed and was intended to be operated by the driver but this was dropped due to cramped conditions inside the fighting compartment.
In 1935 the prototype was constructed in Factory No. 37 in Moscow.6

Usage
During the 1936 peace maneuvers the tanks were installed under the tails of TB-3 bombers and landed during air landing exercises.1
Infantry-tank battalions were issued 38 each.2 Airborne armored battalions were supposed to issued 50 each.2
Based on experience in Finland, in 1940 experiments were carried out with the T-38 being a guide for a radio controlled T-26 explosives carrier. However this never got beyond prototype stages.
Some were used as immobile gun positions during the German invasion.
Captured in the Winter War
T-38s used in the Winter War with Finland. Many were captured in 1941 and turned over to the Luftwaffe and used in the defense of airfields.
