There have been two nuclear weapons detonated as offensive weapons during war. Both nuclear bombs were dropped by the United States on Japan near the end of World War II. The first nuclear weapon (code named "Little Boy") was detonated on August 6, 1945 over Hiroshima, Japan. The second (code named "Fat Man") was on August 9, 1945 over Nagasaki, Japan. The destruction was so horrific, that the fact of the destruction has served as a deterrent to the use of nuclear weapons ever since.
