Design/Production
A new design of the T-37 was developed at the AMO auto works in 1936 and was designated the T-38.
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.
Description
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.
T-38-M2:
In 1938 improvements were made to the gearbox and the engine was replaced with a GAZ M1.
T-38TU:
Command version with extra antenna.
Usage
During the 1936 peace maneuvers the tanks were installed under the tails of TB-3 bombers and landed during air landing exercises.
Infantry-tank battalions were issued 38 each. Airborne armored battalions were supposed to issued 50 each.
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.
T-38:
Were 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.
