This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons.
South Africa successfully built six nuclear weapons in the 1980s, but dismantled all of them in the early 1990s, shortly before the fall of the apartheid system. [23] So far it is the only nuclear-capable country to give up nuclear weapons, although several members of the Soviet Union did so during the collapse of the Soviet regime.

France had been heavily involved in nuclear research before World War II through the work of the Joliot-Curies. This was discontinued after the war because of the instability of the Fourth Republic and lack of finances. [76] However, in the 1950s, France launched a civil nuclear research program, which produced plutonium as a byproduct.
The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons.As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II.
The United States was the first country to manufacture nuclear weapons and is the only country to have used them in combat, with the bombings of Hiroshima and Nagasaki in World War II against Japan. Before and during the Cold War, it conducted 1,054 nuclear tests, and tested many long-range nuclear weapons delivery systems. [Note 1]
Like most strategic bombing during World War II, the aim of the air offensive against Japan was to destroy the enemy's war industries, kill or disable civilian employees of these industries, and undermine civilian morale. [39] [40] Over the next six months, the XXI Bomber Command under LeMay firebombed 64 Japanese cities. [41]
