In the fall of 1938, additional trials were held. After all faults were removed, the tank saw service under the designation ST vz.39. The vehicle never entered mass production.

This variant of the M3 Lee was manufactured in the United States specifically to be supplied to the U.K., where it was designated the General Grant (Grant I).
