Nuclear fission Mexico, which was the scientific hub for research on bomb development and design. Other sites, notably the Berkeley Radiation Laboratory and the Metallurgical Laboratory at the University of Chicago, played important contributing roles. Overall scientific direction of the project was managed by the physicist J. Robert Oppenheimer. In July 1945, the first atomic explosive device, dubbed "Trinity", was detonated in the New Mexico desert. It was fueled by plutonium created at Hanford. In August 1945, two more atomic devices – "Little Boy", a uranium-235 bomb, and "Fat Man", a plutonium bomb – were used against the Japanese cities of Hiroshima
Nuclear weapons in popular culture imagery. Orchestral Manoeuvres in the Dark's 1980 song "Enola Gay" depicts the events of the 1945 deployment of nuclear weapons on Hiroshima from the point of view of the crew of the B29 Superfortress Bomber Enola Gay. Clear references are made to the exact time the bomb detonated ("It's eight fifteen, and that's the time that it's always been"), and questions are asked as to whether the action was necessary. The song also references a supposed radio message in which the crew detail no anomalies as a result of nuclear detonation ("We got your message on the radio - conditions
