In what year was the atomic bomb successfully launched in Mianyang City, Sichuan Province?

1964 65438+1October 16 At 3 pm, over Lop Nur, Xinjiang, in the west of China, China lifted the huge fireball and mushroom cloud of atomic nuclear fission onto the Gobi Desert for the first time, and the first atomic bomb exploded successfully. About this time, the central government made a new decision and decided to build a nuclear weapon research and development base codenamed "Project 902", which was distributed in the mountainous areas of Mianyang and Guangyuan in Sichuan Province.

On June 1967, China shocked the world again and successfully exploded the first hydrogen bomb. This test is another leap in the development of China's nuclear weapons after the successful explosion of the first atomic bomb, marking a new stage in the development of China's nuclear weapons.

At the beginning of 1960, according to the situation after the Soviet Union's 596 letter, Zhou Enlai instructed that "we should start from scratch and prepare to build an atomic bomb in eight years." Nine research institutes have expanded their scale. Zhu Guangya was transferred to be the deputy director of nine institutes, in charge of scientific research, internship, production planning and academic activities; Set up four departments of theory, experiment, design and production, 13 research room. The director and deputy director of the theory department are Deng Jiaxian and Zhou; Long, director of the design department. Zhang Xingyuan, director of the experimental department.

Director of the Second Technical Committee of Wang Jiuyuan directed the basic principle test of the atomic bomb and the design and test of the ignition neutron source generator. Peng Huanwu, Director of the Third Technical Committee. Guo Yonghuai, director of the Fourth Technical Committee, directs the research on the mechanical properties of nuclear weapons, including structural strength, pressure distribution and vibration.
