China has its own missile nuclear submarines, and for the first time successfully launched a long-range launch vehicle under water, it was the first to complete China's "three-in-one" strategic nuclear strike system, which shocked the world!

Nuclear submarine is a type of submarine, nuclear submarine with nuclear reactor as the propulsion power source, strong underwater endurance, long self-sustaining time, can be lurking in the water for a long time, has a far superior combat ability and a wider range of activities than conventional submarines. It can be equipped with ballistic missiles with nuclear warheads or flying missiles. In military wars, it has attracted much attention because of its strong endurance surname. Nuclear submarines are also the most powerful killer against aircraft carriers.

According to armament, it can be divided into torpedo nuclear submarines, also known as attack nuclear submarines and missile nuclear submarines, also known as strategic nuclear submarines. The Qianlong 101, which China completed this underwater launch mission, is the latter missile nuclear submarine. It is equipped with a missile compartment and is used to complete a variety of missions such as anti-submarine, anti-ship and attack on land targets, and has advantages that land-based strategic weapons cannot match. Therefore, it is called the "second nuclear strike force" by military experts. Missile nuclear submarines are the most important strategic strike force of a nuclear-weapon state, and they are also the most important indicator of nuclear strike capability.

The world's first nuclear submarine was the USS Nautilus, which was built by the American scientist, known as the "father of nuclear submarines". Rickover's developed and built. In 1946, Rickoverer and a group of scientists began working on the atomic reactor for ships, which was later widely used on submarines. In June 1952, the construction of the Nautilus nuclear submarine began, and the first sea trials began on January 24, 1954.

The first test voyage showed the superiority of the nuclear submarine, people could not hear the rumbling noise of the conventional submarine, and the crew on the boat could not even perceive the difference with sailing on the water, and dived 1,300 kilometers in 84 hours, which exceeded the maximum range of any conventional submarine by about 10 times.

Due to its large endurance, nuclear submarines do not need to surface, so they are difficult to detect, can avoid air attacks, and even if they are discovered, the high speed of nuclear submarines can make them escape from pursuit. In August 1958, the Nautilus crossed the Arctic Ocean ice cap from under the ice and sailed from the Pacific Ocean into the Atlantic, accomplishing a feat unimaginable by conventionally powered submarines. After that, the United States announced that it would no longer create conventionally powered submarines in the future. The full nuclearization of American submarines was gradually achieved.

Four years after the United States, in 1958, the Soviet Union's first K-3 nuclear submarine also completed the historic feat of diving from the ice to the North Pole for the first time, raising the Soviet flag on the ice at the North Pole.

Another 4 years, China also has nuclear submarines. However, at this time, the nuclear submarines of the United States and the Soviet Union were equipped with only six 533-millimeter torpedo tubes and could carry 18 torpedoes. The "Qianlong" missile submarine is equipped with 12 JL2 submarine-launched missiles, all of which are made of graphite epoxy fiber shells, new high-energy NEPE propellants, throwable extension nozzles, and other most advanced technologies in the world. Although the range of the JL2 SLBM is not as far as 12,000 kilometers in later generations, it is enough to reach more than 8,000 kilometers now.

China again has its own nuclear submarines. Why has China created so many puzzling sophisticated weapons and equipment in such a short period of time? It has always been a mystery in the minds of many Westerners.

A country's core interests are guaranteed and safeguarded by the country's strong determination and strong military force. The base headed by Deng Feng came to this era, and in order to meet the challenges that China will face in the future, the snow will remove the great shame and humiliation brought to the Chinese nation by the Western imperialist powers over the past 100 years or so in modern times. Only by making use of the modern scientific and technological knowledge and equipment in our own hands can we seize the commanding heights of China's electronic information industry and enable China to achieve leapfrog development.

In line with this purpose, they firmly grasped the key that science and technology are the primary productive forces, and when the premier came to inspect the base and discuss the first five-year plan, the party committee of the base submitted to the premier a "Longteng Project Plan," which identified seven high-tech fields that have a major impact on China's future development, and formulated corresponding goals:

1. In order to solve the problem of feeding China's 500 million people, in terms of agricultural technology, it is necessary to actively study and popularize new varieties of animals and plants with high yield, high quality, and resistance to stress, and vigorously develop the chemical fertilizer industry to promote stable and high agricultural yield.

2. In order to make the quality of life more quality for Chinese and improve the health level of the people of the whole country, various vaccines and antibiotic drugs have been produced.

3. In terms of space technology, research and development of advanced artificial satellites, large carrier rockets and space-to-earth transportation systems; Study the manned space station and its applications and occupy the supremacy of space.

4. In terms of information technology, increase chip development, vigorously develop the computer industry, and meet the needs of intelligent computer systems in multiple fields; Research on optoelectronic devices and integrated technologies for optical communication and optical computing.

5. In the field of laser technology, research high-energy, high-quality laser technology, in order to drive the development of plasma, new materials, laser spectroscopy and other technical sciences, and expand the application of laser in production.

6. In the field of nuclear technology. We will develop nuclear technology for national defense and civil use, carry out research on advanced nuclear reactions that can greatly improve the utilization rate of nuclear fuel, and build engineering reactors.

7. In the field of new materials, it provides key materials for various related fields of the national high-tech plan, new optoelectronic information materials for the next step of information technology services, high-temperature-resistant, wash-resistant, high-toughness composite materials for power plants, corrosion-resistant, lightweight structural materials and some functional materials for aerospace technology.

In order to realize the "Longteng Engineering Plan", the base has put forward the guarantee measure of talent strategy. He pointed out that China is a big country of talents, because of the large number of talents, and at the same time, it is a small country of talents, because the proportion of professionals in the number of employees is too small. In particular, there is a serious shortage of key talents related to national economic and social development, such as senior professional and technical personnel, high-tech talents, and high-level management personnel. In order to catch up with and surpass the United States, it is necessary to regard the implementation of the talent strategy as the first strategy for China's development, intensify the development of human resources, and establish and improve a scientific mechanism for the training, development, and use of qualified personnel. And in the "Longteng Project Plan", Qian Xuesen, Hua Luogeng, Qian Weichang, Qian Sanqiang, Deng Jiaxian and other 1,000 famous scientists and academic leaders in later generations were listed as a group of outstanding intellectuals urgently needed in China. After 10 years of hard work, gratifying achievements have finally been made in various fields.

In April 1951, the Supreme Commander put forward the directive on streamlining and reorganizing the armed forces, and at the same time put forward the demand for modernizing the armed forces' equipment and building up a strong national defense force. And commissioned the base to draft a plan for the modernization of China's defense as a whole. Accordingly, Deng Feng put forward his own opinions on the development of China's affairs and drafted a "Confidential Report on the Development of China's Affairs," which comprehensively expounded China's national defense system, national defense construction, national defense mobilization and education, national defense expenditure, national defense industry construction, military legal system construction, military training, logistics construction, political and ideological construction, and armed equipment construction. This report became a programmatic document for China's national defense construction during this period, guiding China's armed forces toward revolutionization, modernization, and informationization.

In October 1951, entrusted by the Central Military W, under the organization of Liu Jun and others, the base compiled the "Outline for China's Five-Year National Defense Construction and Development" in accordance with the guidelines for the construction of armed equipment in the "Confidential Report on Chinese [Chinese] Affairs", with reference to the equipment standards of the Chinese People's Liberation Army in later generations, and in combination with the industrial base and manufacturing capacity at that time, and sent a large number of technicians to participate in the organization of design and production. They made full use of the achievements of military scientific research at home and abroad in later generations, strengthened exchanges with engineers and technicians of various military industrial departments and departments, and promoted the rapid transformation of scientific and technological achievements in later generations in this era. Together with the cadres and workers of the vast number of military industrial enterprises, they have overcome numerous difficulties, while building, producing, and equipping the troops, and at the same time training and maintenance personnel for the troops. As soon as possible, the military achievements of later generations should be transformed into the combat effectiveness of the Chinese People's Liberation Army in this era. The production of advanced military products has greatly promoted the continuous improvement and improvement of China's industrial system, greatly promoted the transformation of military technology to civilian use, and formed a cycle of mutual promotion between the military and the people.

In 1955, the Central Military W's "China's Second Five-Year National Defense Construction and Development Program" pointed out; "The world is advancing by leaps and bounds, and science is changing rapidly with each passing day. We can only strive for self-improvement, keep innovating, and catch up with and surpass the United States and the Soviet Union at an unconventional speed. Only in this way can we maintain our strategic deterrent. We must not be complacent because of a success, nor can we be complacent because of a one-way view. In the second five-year plan, we must complete the task of manufacturing China's missile attack nuclear submarines and nuclear-powered aircraft carriers and realize the "three-in-one" nuclear strike system, which is what we need to defend our vast territory and vast sea borders.

In May 1952, a large number of elites of Chinese intellectuals, represented by Qian Xuesen, came to the base, and together with those masters and doctors from the base, they jointly established the Fifth Research Institute of the Ministry of National Defense, and made use of the advanced technology, equipment, information, and personnel advantages of the advanced technology, equipment, information, and talents of the advanced times in the base, and realized the leapfrog development of China's strategic strike force at the speed of rockets.

Qian Xuesen personally presided over and participated in the research and development and imitation of rocket engines for ballistic missiles and high-mobility missiles, including surface-to-air, air-to-air, surface-to-ship, ship-to-ship and other missiles, as well as turbine engines for long-range cruise missiles. In 1954, he also participated in the development of China's first communication satellite. Then he immediately organized and began research on the application of ramjet engines to missiles. China's long-range strike capability has been able to cover the whole world, gradually moving from a dream to a reality.

Strategic missile nuclear submarines are the symbolic equipment of a nuclear power, an important component of the triad of nuclear forces, and the nuclear equipment with the strongest survivability when the other side carries out a strategic strike. The submarine-launched intercontinental missiles carried by it undertake the mission of secondary nuclear strikes, and its deterrent capability is stronger than that of land-based and air-based nuclear weapons.

Qian Xuesen, who is dedicated to "rejuvenating the country through science and technology", his greatest satisfaction is to launch the world's most advanced rocket, increase national strength, strengthen national prestige, and win glory for the nation. Therefore, when he participated in the discussion of the "Second Five-Year National Defense Development Program for China," he resolutely agreed with the proposal of Deng Feng, Liu Jun, and others to once again improve China's strategic strike capability, realize the underwater launch of carrier rockets from nuclear submarines, devote themselves to building the motherland's maritime "Great Wall," and realize China's "three-in-one" strategic nuclear strike system.

The construction of missile nuclear submarines and the underwater launch of missile nuclear submarines is one of the major projects in the "China's Second Five-Year National Defense Development Program" personally approved by the supreme chief.

Qian Xuesen played an irreplaceable key role in the successful launch of the underwater rocket from China's missile nuclear submarine, and he said to several researchers who came to the base: "It is risky to use methods that go beyond the conventional to carry out scientific experiments, but it is also not advisable to completely copy the practices of foreign countries." We should use our brains, make bold breakthroughs, explore a path suited to China's national conditions, and find out China's methods. ”

Under the guidance of Qian Xuesen, China has created a unique characteristic, not that in the history of the United States, the Soviet Union, and other Western countries in the development of missile nuclear submarines, they often had to go through a multi-level experimental ladder before they could enter the underwater launch of nuclear submarines, but through repeated simulations of large-scale computers, they have passed the stage of launching a single-stage rocket and also crossed the stage of launching from a land base, and have adopted the three-step test stage of "Taiwan-tube-boat" for submarine underwater launch tests after being assessed by the land launch pad and launch canister. Out of the path of China's own development of missile nuclear submarines.
