Groves was bold and willing to spend money. When scientists and engineers were unable to decide which of three approaches to producing the fissile material needed to build the bomb, he decided that if nobody could tell which was best, the thing to do was try all three methods. Huge manufacturing facilities were built at Oak Ridge, Tennessee and Hanford, Washington. Assuming that fissile material would be ready, a full-scale effort to design and build the bombs themselves was begun in spring 1943 at the remote desert location of Los Alamos. The scientific and engineering efforts at Los Alamos were managed by [[J. Robert Oppenheimer]].

The first completed bomb was tested on July 16, 1945 at a location code-named "[[Trinity]]." The other two bombs were dropped on Hiroshima and Nagasaki Japan, and ended [[World War II]].

Despite tight security, Communist spies leaked information to the [[Soviet Union]] who soon started a similar project.
