2. 1956, the fifth research institute, the first missile research institute, was established by the Ministry of National Defense, with scientist Qian Xuesen as its president.
3.1In the autumn of 958, 34-year-old physicist Deng Jiaxian became the director of the theoretical department of the Nuclear Weapons Research and Design Institute. He selected 28 experts from Peking University to form the basic scientific and technological force of China's nuclear weapons research.
4. 1959, the theoretical calculation of China's first atomic bomb was successful, and the construction of nuclear industry enterprises with Zhu as the director and Jiang as the chief engineer also achieved initial results. After the Soviet Union withdrew its experts, China readjusted its plan, codenamed "Project 596".
5. 1964 10, China completed the assembly of the first atomic bomb. At 65438+1October 16 15, a huge mushroom-shaped smoke cloud rose into the air in Lop Nur, which was inaccessible, and China's first atomic bomb exploded successfully.
A milestone in the development of China's nuclear weapons;
1. 1964 10 October 16 The first atomic bomb exploded successfully.
2.19665438+February 18 hydrogen bomb principle test was successful.
3.1967 June 17 The first hydrogen bomb exploded successfully.
4.1On September 29th, 988, the first neutron bomb exploded successfully.
5.65438+1The last nuclear explosion test on July 29th, 996 (45th).
6. Since the outbreak of War of Resistance against Japanese Aggression in 1937, the people of China have sacrificed 21000000 soldiers and civilians, but after eight years of arduous and world-renowned war of resistance, they failed to bring the Japanese government to its knees.
7.1On July 26th, 945, the Potsdam Proclamation of China, the United States and Britain urged Japan to surrender unconditionally. On 28th, Japanese Prime Minister Suzuki said that he ignored the announcement and sought to end the war under favorable conditions for Japan. On August 6th and 9th of the same year, 1945, the United States dropped 1 atomic bomb on Hiroshima and Nagasaki respectively. Then less than half a month later, in August of 15, Japan announced its unconditional surrender. We can see the power of strategic weapons from this incident. Therefore, the development of strategic weapons has become the top priority after the founding of New China.
