What is an atomic bomb?

The atomic bomb and nuclear bombs are potent weapons that generate explosive energy through nuclear processes. During World War II, scientists created the first nuclear weapons technology.
Only twice in the history of warfare have atomic bombs been deployed, both times by the US against Japan at the close of World War II, in Hiroshima and Nagasaki.
Following that conflict, there was a time of nuclear proliferation, and during the Cold War, the US and the USSR engaged in a global nuclear arms race for domination.
Fission processes provide the energy for weapons like atomic bombs. Nuclear fusion and nuclear fission are both used in thermonuclear weapons, such as hydrogen bombs.

On August 6 and 9, 1945, respectively, the United States dropped two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The two attacks still stand as the sole instances of nuclear weapons being used in armed combat, killing between 129,000 and 226,000 people, the majority of whom were civilians.
