The Race for the Bomb. He quickly recognized the talents of Marshall's deputy, Col. Entry into, world War II, the War Department was given joint responsibility for the project, because by mid-1942 it was obvious that a vast array of pilot plants, laboratories, and manufacturing facilities would have to be constructed by the. Both of these processes, and particularly the diffusion method, required large, complex facilities and huge amounts of electric power to produce even small amounts of separated uranium-235. The resulting lack of coordination complicated attempts to gain a higher priority for scarce materials and boded ill for the future of the entire bomb project. Groves was placed in charge of all Army activities (chiefly engineering activities) relating to the project.
II that produced the first nuclear weapons. It was led by the United States. The Manhattan Project was the result of an enormous collaborative effort between the.S.
Each of the four isotope separation processes remained under consideration, but a full-scale commitment to all four posed serious problems even with the project's high priority. In the summer of 1939, Albert Einstein was persuaded by his fellow scientists to use his influence and present the military potential of an uncontrolled fission chain reaction to Pres. In one case, for instance, Marshall delayed purchase of an excellent production site in Tennessee pending further study, while the scientists who had been involved in the project from the start were pressing for immediate purchase. An intermediate step in putting this method into production was taken with the construction of a medium-size reactor at Oak Ridge. Only one method was available for the production of the fissionable material plutonium-239.

American scientists, many of them refugees from fascist regimes in Europe, took steps in 1939 to organize a project to exploit the newly recognized fission process for military purposes. Furthermore, Marshall and his Army superiors were disposed to move cautiously. Robert Oppenheimer was created on an isolated mesa at Los Alamos, New Mexico, 34 miles (55 km) north of Santa. The first contact with the government was made.B.
