A Historical Review Of The Use Of 46,000 Parts in The Long March 1 Nuclear Submarine

The development of the Long March 1 nuclear submarine began in the late 1960s when China was almost blank in the field of nuclear submarine technology. Due to the complex international situation at the time, it was necessary to rely on independent research and development to complete this major project.

During the development process, Chinese researchers overcame many difficulties, including the lack of advanced technology and equipment, shortage of funds, and lack of talent. However, they insisted on independent innovation and finally realized the birth of the nuclear submarine. It is reported that all 46,000 parts of the Long March 1 nuclear submarine were independently developed domestically, using more than 1,300 kinds of materials.

As a key material for connecting nuclear submarine parts, the quality of screws is directly related to the safety and reliability of the submarine. Under the technical conditions at the time, China had not yet fully mastered the production technology of screws, so it was once faced with a situation of dependence on imports. However, to ensure the autonomy and controllability of nuclear submarines, the Chinese scientific research team decided to independently develop screws.

Through unremitting efforts, China successfully broke through the technical bottleneck of screws and achieved large-scale localization production. This breakthrough not only provides a guarantee for the success of the "Long March 1" nuclear submarine but also lays the foundation for the localization of subsequent Chinese military products.

The development and launch of the Long March 1 nuclear submarine is a major display of China's scientific and technological strength. According to multiple pieces of evidence, all parts of the submarine are made of domestic materials. This achievement not only reflects China's technological breakthroughs in the field of nuclear submarines but also demonstrates China's independent innovation capabilities in the field of industrial manufacturing.

Specifically, during the development of the Long March 1 nuclear submarine, scientific researchers overcame a large number of technical difficulties, including the design of the nuclear reactor, the optimization of the hull structure, and the integration of various complex systems. These achievements are inseparable from the support of basic materials such as domestic screws.

The successful launch and service of the Long March 1 nuclear submarine not only made China the fifth country or region in the world to have nuclear submarines but also marked an important step for China in the field of national defense science and technology. The complete localization of this nuclear submarine, including the use of domestic screws, reflects China's independent innovation capabilities and strong comprehensive strength in the field of industrial manufacturing.

At the same time, the success of the Long March 1 nuclear submarine also inspired the localization development of a series of subsequent military products. For example, after the 1970s, China gradually realized the localization production of weapons and equipment such as tanks and fighters, which were inseparable from the technical experience and material research and development capabilities accumulated in the early development of nuclear submarines.

In the process of developing domestic screws, the Chinese scientific research team mainly faced many technical difficulties such as material selection and processing difficulty, high strength and precision manufacturing, sealing and reliability, manufacturing process complexity, independent intellectual property rights and technology blockade, technical challenges of special application scenarios, and cost and efficiency issues. The solution of these problems not only promoted the progress of domestic screw technology but also provided valuable experience for the research and development of other industrial basic components.

The historical review of the use of domestic screws by the Long March 1 nuclear submarine fully demonstrated China's independent innovation spirit and technical strength in the development of nuclear submarines. From complete dependence on imports to full localization, the success of the "Long March 1" is not only an important milestone in China's scientific and technological history but also an important starting point for China's military industry to move towards independence. This achievement not only provides a solid guarantee for China's national defense construction but also lays a solid foundation for the subsequent localization development of military products.
