T-33

The T-33 was an early prototype of the T-37 light amphibious tank. It was based upon the Carden-Loyd tankettes purchased from England. The only unit was completed in March 1932 designated "Morskoi 33". It had a 360 degree moving turret placed in the centre line of the hull, and a crew of two men, whose only weapon was a machine gun. The speed (on land only) was quite good. In 1933 a second unit, fully amphibious and with new suspension, became the T-37.

It was nearly an exact copy of the British Vickers Carden-Loyd A4E11 Tankette. The second prototype got a wheel suspension from the Renault AMR-33.
