The bomb exploded over Hiroshima at 8:15 on the morning of August 6, 1945. About an hour previously, the Japanese early warning radar net had detected the approach of some American aircraft headed for the southern part of Japan.
   In 1945 Hiroshima became the first city ever to be bombed by an  atomic bomb. The second Japanese city, Nagasaki, was bombed on the  9th of August.    This was the only time that nuclear weapons have been used in  warfare.
