In the history of warfare, nuclear weapons have been used only twice, both during the closing days of World War II. The first event occurred on the morning of August 6, 1945, when the United States dropped a uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The 2nd event occurred 3 days later when the United States dropped a plutonium implosion-type device code-named "Fat Man" on the city of Nagasaki. The use of these weapons, which resulted in the immediate deaths of around 100,000 to 200,000 people and even more over time, was and remains controversial.
Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over 2,000 occasions for testing and demonstration purposes. The only countries known to have detonated such weapons are (chronologically) the United States,Soviet Union, United Kingdom, France, People's Republic of China, India, Pakistan, and North Korea.
At the beginning of the Apollo program Kraft retired as a flight director in order to concentrate on management and mission planning. In 1972 he became director of the Manned Spacecraft Center (later Johnson Space Center), following in the footsteps of his mentor Robert Gilruth. He held the position until his retirement from NASA in 1982. During his retirement, Kraft has consulted for numerous companies including IBM and Rockwell International, and he published an autobiography entitled Flight: My Life in Mission Control.
