The Soviet T-40 amphibious scout tank entered production just prior to the outbreak of World War II, intended to replace the earlier T-37A and T-38 types in equipping reconnaissance units. Water propulsion was achieved via a small propeller set into an indent in the hull rear, and was thus better protected than the exposed propeller of the T-38. Buoyancy was provided by the large boat-shaped hull. The vehicle's armament consisted of a single 12.7 mm DShK 1938 machine gun to replace the 7.62 mm DT-29 machine gun on the T-37 and T-38, mounted in a small, fully-rotating turret offset to the left side of the vehicle. It carried a crew of two, had a maximum land speed of 28 mph, and weighed 5.9 tonnes. The vehicle served mainly in Operation Barbarossa and the defense of Moscow; it was rarely seen after that, though training schools used it until 1946. Soviet industry produced only 962 units in 1940 and 1941, when priorities shifted to less-complex designs.
