Orlik 046 Lekki czołg pływający T-37

The T-37 is a Soviet light amphibious tank from the interwar period and World War II. The first prototypes of this vehicle were built in 1931-1933, and the car entered service in 1933. The combat weight of the tank was up to 3.2 tons. The drive was provided by a single 40 HP GAZ-AA carburettor engine. The armament consisted only of the DT 7.62 mm machine gun.

The T-37 floating light tank was clearly inspired by Western designs, especially the British wagon Vickers-Carden-Loyd Amphibian, which were purchased by the USSR in 1932. Initially, the prototypes of the T-37 caused a lot of problems, but they were removed when the vehicle was put into series production. It is worth adding that the T-37A version was mainly produced in its course. However, several development versions, projects or prototypes were created, among which the following can be mentioned: SU-37 (a project of a self-propelled gun armed with a 45mm cannon), OT-37 (a version with a flamethrower) or the T-37RT (a command vehicle with handrail antenna). The T-37 vehicles were used in combat during the aggression against Poland in September 1939, during the Winter War (1939-1940) and in the initial phase of the German-Soviet war in 1941.
