1On July 6th, 945, the world's first atomic bomb "Thin Man" successfully exploded in the Muto Desert in Horner Dader, New Mexico, USA, with a power equivalent to 20,000 tons of TNT.

This test explosion is called the "Sany Nuclear Test" and belongs to the "Manhattan Project" of the United States to develop an atomic bomb. Its research and development began in 1942. The purpose of this plan is to develop a new weapon that can be used to defeat Nazi Germany.

1942, the American government formally established the Manhattan Project Working Group. Because nuclear weapon is a brand-new weapon, many new physical principles and technologies need to be used in the development process. In order to achieve this goal, the United States government recruited some famous scientists and engineers from all over the country, who conducted intensive research work in laboratories all over the country.

In the development process, the US military must first find suitable materials to make atomic bombs. In the end, they chose uranium -235 and plutonium -239, which can generate huge energy through fission reaction. But these substances are very scarce, so they need a lot of resources and technology to obtain.

Subsequently, scientists began to design and manufacture nuclear reactors, accelerators and other equipment. These devices need to be manufactured and debugged accurately to ensure that the reactor can run stably under control without accidents.

Finally, in 1945, the research team of Manhattan Project conducted the first nuclear fission experiment in a laboratory named "Los Alamos" in New Mexico. This experiment successfully released huge energy, which proved that nuclear reactors can be used to make atomic bombs.

Next, the US military began a series of experiments and tests, and finally/kloc-0 dropped the first atomic bomb in Hiroshima, Japan on August 6, 945. The atomic bomb was named "Little Boy", which instantly destroyed most parts of Hiroshima, causing more than 65,438+10,000 casualties.

The world's first atomic bomb was developed through the research and efforts of the Manhattan Project. Although the manufacture of the atomic bomb is an extremely complicated and dangerous process, its appearance has changed the pattern of the world, at the same time, it has made people aware of the terrible consequences of nuclear war and promoted the process of global nuclear disarmament and peaceful coexistence.
