Weapons of Mass Destruction (WMD)

China's Improved Designs

In 1967, the Ninth Academy started to conduct research on nuclear weapons that were both smaller in size and weight and more powerful than the others. In 1967, development of thermonuclear missile warhead began. Objectives were small size, light weight, safe and reliable, easy to use, detonation control system reliability, environmental adaptability and miniaturization design; reliability of the size of detonation and other key technical aspects. Work included test techniques and non-nuclear explosion with the identification of nuclear devices Flight test methods, as well as the development of more advanced performance, more complex functions, relatively complete types of large-scale equipment and ground testing equipment and other aspects of research and achieve the desired results. In order to meet the technical requirements for weapons and tactics, a series of work such as large-scale detonation tests, mechanical and environmental conditions tests, flight tests of weapons components and detonation control systems in the missile's head were carried out.

After the nuclear device qualification test is completed, the Nuclear Weapons Institute would conduct trial production of the products according to the finished design drawings and technical documents so as to achieve the purpose of repeatedly producing the products that meet the design requirements and then submit a summary report of the weapons development as well as the design drawings, technical documents and Craft information, were submitted as designs in order to carry out mass production of weapons. From the early 1970s to the mid-1980s, the Institute completed the production and equipment of mid-range, medium-range, intercontinental and submarine missiles supporting thermonuclear warheads.

For the nuclear warhead miniaturization test, the Central Special Committee approved the Q-5A 11246 airdrop. In 1970, a theoretical design proposal of smaller hydrogen bomb detonation bomb (ie trigger) was proposed. In order to test the correctness of the design and to explore the characteristics of smaller detonators, a Q-5-type upper-thrown toss-bombing method was adopted to conduct a pilot test of smaller hydrogen-bomb detonation bombs.

In December 1970 designers were ready to test, but it was decided to postpone, and a few months later they modified the theoretical design. After the delay in the bombing, at 13:00 on 30 December 1971, Yang Guoxiang attempted to drop a small hydrogen bomb, but the test failed because the bomb would not detach from the aircraft.

Subsequent nuclear tests (CHIC 12, CHIC 13) were suggestive of a new phase of the PRC test programs. Both were low yield weapons. It appeared that CHIC 13 was delivered by an Q-5 aircraft and may have been a proof test of a weapon.
