not to be confused with Škoda 15 T, a modern tram The T-15 was an experimental German-Czechoslovakian light tank developed by Škoda Works for the German armed forces from 1941 to 1943. The T-15 never entered mass production or combat, and only no more than five prototypes - including two in mild steel - were built. The T-15 weighed 11-13 tonnes, and was armed with a 37mm gun and MG34 machine gun. Interest in the development of the tank declined in 1942 as the Panzer II Ausf. L was more advanced, however Skoda continued the development project.
