Before World War II, The Soviets produced light amphibious tanks called the T-37A and T-38. A third serial model, the T-40, started production after the beginning of the war. A 14-ton tank, the PT-1, was created but was not mass-produced. In addition, an attempt was made to attach pontoons to the T-26. While successful, the project was closed due to the high vulnerability and unwieldiness of the construction.
