The Manhattan Project was a massive, top-secret national mobilization of scientists, engineers, technicians, and military personnel charged with producing a deployable atomic weapon during World War II. It resulted in the first successful test of an atomic device on July 16, 1945, a few weeks before the United States dropped atomic bombs on Hiroshima and Nagasaki, Japan. Coordinated by the U.S. Army, Manhattan Project activities took place in numerous locations across the United States. The park is managed through a collaborative partnership by the National Park Service and the U.S. Department of Energy, and incorporates three of the Manhattan Project’s most significant locations: Oak Ridge, Tennessee; Los Alamos, New Mexico; and Hanford, Washington.
