Stunning Footage!!! This an amazing compilation of Atom Bombs!
Nations that build nuclear weapons need to test by conducting experiments to determine the effectiveness, yield, and explosive capability of nuclear weapons. It is also a display of power might and nuclear testing has been used by Nations to underscore their scientific and military strength. and Many tests have been overtly political in their intention by making it clear that they have nuclear capabilities.
The first nuclear device was detonated as a test by the United States at the Trinity site on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of engineer device, codenamed “Mike”, was tested at the Enewetak atoll in the Marshall Islands on November 1, 1952 (local date), also by the United States. The largest nuclear weapon ever tested was the “Tsar Bomba” of the Soviet Union at Novaya Zemlya on October 30, 1961, with the largest yield ever seen (as of January 2016), an estimated 50–58 megatons.
In 1963, three (UK, US, Soviet Union) of the four nuclear states and many non-nuclear states signed the Limited Test Ban Treaty, pledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space. The treaty permitted underground nuclear testing. France continued atmospheric testing until 1974, and China continued until 1980. Neither has signed the treaty.
