However, the second effort began under the administrative auspices of Wermacht's Heereswaffenamt on the day World War II began, 1 September 1939. The program eventually expanded into three main efforts: the Uranmaschine (nuclear reactor), uranium and heavy water production, and uranium isotope separation.
