Nuclear weapons are the general term for weapons that use energy released by self-sustaining nuclear fission or fusion reactions to produce explosive effects and have mass destruction and destruction effects. Among them, the fission weapon made by the fission chain reaction principle of heavy atomic nuclei such as uranium 235 (or plutonium 239) is mainly used, which is usually called atomic bomb; ) The thermonuclear or fusion weapon made by the thermonuclear reaction principle of light atomic nuclei is called a hydrogen bomb.
On July 16, 1945, the United States successfully exploded the world’s first atomic bomb.[1]1945 On August 6, 2010, the United States used the B-29 bomber to carry the "Little Boy" atomic bomb to bomb Hiroshima. [2]

The United States dropped an atomic bomb on Hiroshima, Japan on August 6, 1945. It caused a large number of civilian and military casualties. This incident is still fresh in people’s memory. It has to be said that the power of the atomic bomb is indeed great. Part of the reason that will make Japan announce its unconditional surrender can be said to be the "atom bomb." It is a weapon that uses the huge energy released by nuclear fission to kill, and can effectively prevent the other side’s military operations to achieve strategic goals.
In 1964, China successfully exploded an independently developed atomic bomb, which made the Chinese stand upright. The explosion of the pole made the world look at China with admiration. China’s development of nuclear weapons is to break the monopoly of nuclear powers and to protect the motherland from bullying, and the Chinese government promises: China will not use nuclear weapons first at any time and under any circumstances.
