The Joe-1 atomic bomb test by the Soviet Union that took place in August 1949 came earlier than expected by Americans, and over the next several months there was an intense debate within the U.S. government, military, and scientific communities regarding whether to proceed with development of the far more powerful Super.

He invented the idea of an atomic bomb in 1933 while crossing a London street in Russell Square. He patented it in 1934. (British patent 630,726) 1934 – Enrico Fermi conducts experiments in which he exposes uranium and thorium to neutrons to create distinct new substances.

His leadership and scientific expertise were instrumental in the project's success. On July 16, 1945, he was present at the first test of the atomic bomb, Trinity. In August 1945, the weapons were used against Japan in the bombings of Hiroshima and Nagasaki, to date the only use of nuclear weapons in an armed conflict.
The atomic bomb was a part of China's "Two Bombs, One Satellite" program. It had a yield of 22 kilotons , comparable to the Soviet Union's first nuclear bomb RDS-1 in 1949 and the American Fat Man bomb dropped on Nagasaki, Japan in 1945. [ 4 ]
The United States tested the first nuclear weapon in July 1945, the Trinity test, with the atomic bombings of Hiroshima and Nagasaki taking place one month later. In August 1945, the first widely distributed account of nuclear energy, the pocketbook The Atomic Age, [14] was released.
There are other types of nuclear weapons as well. For example, a boosted fission weapon is a fission bomb that increases its explosive yield through a small number of fusion reactions, but it is not a fusion bomb. In the boosted bomb, the neutrons produced by the fusion reactions serve primarily to increase the efficiency of the fission bomb.
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.
