On this day, 37 years ago, on September 27, 1988 (August 17, 1988, the lunar calendar), our nuclear submarine successfully launched a launch vehicle underwater. On September 27, 1988, my country's launch of carrier rocket tests into predetermined waters ended (starting on September 14). The launch vehicle for this test was launched from underwater by a nuclear submarine developed by my country. The rocket accurately splashed down in the predetermined sea area, and the entire test was a complete success. On September 28, 1988, the People's Daily published a long newsletter "The Birth of China's Nuclear Submarine", which recorded the launch and the development of nuclear submarines. It writes: The successful launch of a launch vehicle by a missile nuclear submarine marks that my country's cutting-edge national defense technology has jumped to a new level. Our government has long declared that China will never become a superpower and has no intention of participating in the world arms race. We develop missile nuclear submarines to defend peace. In the late 1950s, Marshal Nie Rongzhen reported to the Party Central Committee with the courage and foresight of a strategist that our country would develop nuclear submarines. When General Secretary Deng Xiaoping forwarded this report to the Chairman and Standing Committee of the Party Central Committee, our scientists only had two photos in the shape of foreign nuclear submarines. However, Chairman Mao Zedong, Premier Zhou Enlai and Defense Minister Peng Dehuai immediately approved the report. At that time, China was holding talks with the top leaders of relevant countries, and we asked the other party to provide relevant technical information. The other party refused outright, believing that my country's industrial foundation, technological strength and scientific level did not have the minimum conditions and could not be achieved at all. Chairman Mao Zedong did not believe in evil spirits and made up his mind: "Nuclear submarines will be built in 10,000 years!" The construction of nuclear submarines has brought together China's best scientific and technological talents. Among this scientific and technological team are physicists, shipbuilding experts, nuclear reactor experts, and rocket experts; students from the late Qing Dynasty who returned from studying abroad with the Boxer Compensation; scholars who were depressed during the Kuomintang period and were unable to display their talents; new intellectuals who had just taken off their military uniforms and been trained from accelerated schools; and high-quality students who graduated from the first few universities of the Republic. What a gathering of elites! They began a difficult journey. The most basic conditions are integrated with the most cutting-edge technology, and what connects these two points is the unique dedication and sacrifice spirit of scientific and technological personnel. Over the long years, the hardships of the environment, the hardships of starting a business, and the changes of the situation have not shaken their original intention of dedicating themselves to developing nuclear submarines. China's nuclear submarine not only embodies the efforts and efforts of thousands of scientists, thousands of shipbuilders, and thousands of sailors, but also embodies the cost paid by more than 20 provinces, municipalities, autonomous regions and more than 2000 factories and research institutes across the country. An expert told us such a touching story: More than 20 scientific researchers from all over the motherland gathered together to undertake the task of developing nuclear submarine missile launchers. After going through hardships and ups and downs, they finally developed a missile launcher with international advanced standards. No one can count how many famous and unknown people like special fuel developers are in the development of nuclear submarines. We only know that more than 20 provinces, municipalities, autonomous regions and thousands of scientific research units and factories across the country participated in the research and development work; I also know that almost every research and development unit encounters the problems of high quality requirements, small production quantities, little profits, and even unprofitable or even losing money, but no one refuses this. In the turbulent years, many factories were shut down, but a nuclear submarine project mission document could call workers back to the workshop... Nuclear submarines inspired the cohesion of our nation, and national cohesion gave birth to nuclear submarines! The good news that the carrier rocket was successfully launched and the accurate splash down was quickly transmitted back to the command post hall. A science and technology worker in the hall with frosted temples was so excited that he couldn't help but be excited by the good news. People came forward to surround him and warmly congratulated him... His name is Huang Xuhua, the chief designer of my country's nuclear submarine. Mr. Huang is 62 years old. The second half of his life was closely linked to the development of my country's nuclear submarine and made important contributions to its birth. Since he was appointed as deputy chief engineer of the Nuclear Submarine General Research Institute in the early 1960s, a huge workload in development has been on his shoulders. He will chair the collaborative research meeting; He had to make the final decision on the demonstration of the design plan; he had to "solve the problem" when encountering difficulties in cutting-edge projects... At the critical juncture of the development work, he had been running around continuously and did not visit his house all year round. He was called "flying" by his colleagues." As the chief designer, Huang Xuhua has extraordinary courage and wisdom in solving difficult problems in development. When people are troubled by problems, he can always lead everyone from "recovery of mountains and heavy waters" to "bright flowers in willows". Such a huge system project as a nuclear submarine required extremely meticulous dispatch. At that time, the engineering was urgent, and many projects were designed and constructed simultaneously. After the overall final design, the weight of the boat gradually expanded, which adversely affected the balance of the boat. People racked their brains. Based on extensive listening to everyone's opinions, Huang Xuhua made a decision to enable the nuclear submarine to sail smoothly in groundwater. Some people call the chief designer the "father of nuclear submarines" of China, but he flatly denies it: "In the development of nuclear submarines, I only tried my best to do what should be done in my own position. "As he said this, he pointed to Peng Shilu, Zhao Renkai, Huang Weilu, Chen Deren and other scientists and research designers beside him and said: " If you want to talk about the fathers of China's nuclear submarines, they are all worthy of being called." Yes, those scientific and technological workers who worked hard for the birth of China's nuclear submarines are the fathers of China's nuclear submarines. It is precisely because of such a large number of scientific and technological workers that China can enter the world's advanced ranks in the field of cutting-edge technology. We are proud and proud to have such a large number of scientific and technological workers.
