It is precisely because of the comprehensive implementation of the "Four Three Plans" that China has truly gained a sober understanding of the outside world, especially the developed countries in the West.

A large number of complete sets of technical equipment introduced by the four three plans not only bring advanced technology, advanced technology and advanced equipment from western developed countries, but also bring advanced management concepts and management methods, and bring a wide range of the latest market information.

Through the introduction of this batch of equipment, we have personally felt the changes in the outside world, and seen what is advanced technology, what is highly developed industry, and what is efficient labor productivity. Only then can we have a clearer and deeper understanding of the gap between China and the developed countries in the West.

How should the road of China's industrialization go, without the introduction of this large number of complete sets of projects in the "four or three plans", it will not be felt.

Huaxia's current gas turbine factories and industrial steam turbine factories can be said to be the results of the "four or three plans" of the year.

Chai Lao not only has a deep insight into the economic and technological development trend of the world, but also has a tenacious obsession with the development of the shipbuilding industry.

Although the pattern of competition between the east and the west has taken shape, the shipbuilding industry, which has always been under the leadership of the Commission of Science, Technology and Industry for National Defense, is full of shadows of close cooperation between the southeastern coastal provinces and the western region.

And this kind of cooperation is a full embodiment of Chai Lao's coordination ability.

Today's Chinese shipbuilding industry has undergone earth-shaking changes compared to the early 70s.

After the introduction of the technology of the German shipyard in Howatz, Germany, and the successful application of the giant section shipbuilding method, China's ability to manufacture large ships has been qualitatively improved.

The technical upgrading of Huhai Changxing shipbuilding base has also led to the overall industrial upgrading of Dalian Shipyard.

The two shipbuilding bases in the north and south have paved the way for the expansion of China's shipbuilding industry and paved the way to become a shipbuilding power.

In particular, the successful development of RQ79 series gas turbines and ZQ79 series steam turbines has provided a strong domestic heart with the world's first-class advanced level for China's small, medium and large military and civilian vessels.

As the leader in charge of the national shipbuilding industry. Chai Shufan is now both smooth and handy. Which school he works no less than ten hours a day, not only has he not seen old age. On the contrary, it looks even more old and strong, and the spirit of Ryoma.

In the office, Chai Shufan got up from the sofa and took the hot tea that Yang Weiping personally made for him, and said with a smile full of joy in his old eyes: "Director Yang." You suddenly interrupted your vacation, and I think you must have heard the good news that our Julang-1 missile was successful in its first submarine launch, so you hurried back, right?"

"Julang Type 1 succeeded?" Yang Weiping's eyes widened in surprise. Looking at Chai Shufan with a blank eye, he asked eagerly, "Chai Lao, you're not joking with me, are you?"

"Such a big happy event, how can I joke with you Director Yang!" Chai Shufan nodded with a smile and replied: "It was successful! At half past ten o'clock last night, our first Julang-1 submarine-launched missile was successfully test-fired on the Type 031 ballistic missile submarine!"

Although the test launch was carried out on a Type 031 ballistic missile conventionally powered submarine, rather than a nuclear submarine, Yang Weiping still felt inexplicably excited and excited.

Because. This Julang 1 is not the Julang 1 of the previous generation of Huaxia, but adopts the design concept of Julang 2 with a first-stage solid rocket engine and a second-stage liquid rocket engine.

It has to be said that the success of the WS6H1 core engine has a positive impact on the development of China's engine industry. It has played a milestone significance.

On the basis of the WS6H1 core engine, it has not only successfully developed the WS10 high-thrust Taihang engine, WS9 medium-thrust Qinling engine, WS12 low-thrust Taishan engine, WZ16 high-horsepower turboshaft engine, WS8 high-bypass ratio high-thrust Kunlun engine, but also provided strong technical support for the successful research and development of RQ79 series gas turbines, ZQ79 series steam turbines, GTH79 series solid rocket engines and YTH79 series liquid rocket engines.

It is precisely with the successful application of the GTH79 series of solid rocket engines, the C802 Eagle Strike anti-ship missile, the PL series of short, medium and long-range air-to-air missiles and air-to-surface missiles, that they have strong horsepower that is not inferior to foreign first-class missiles.

CHINA'S FIRST GENERATION OF SOLID ROCKET ENGINE, BORN IN OCTOBER 1966, DIAMETER 1340MM. It was also from this time that the development of the submarine-to-surface ballistic missile "Julang-1" began.

During the 10 years of turmoil, research on the Julang-1 missile was not interrupted.

However, to directly develop a two-stage medium-range solid-state missile beyond the short-range single-stage stage means that we will face many difficulties, such as a high starting point, great technical difficulties, lack of data, drawings and imitation samples, and lack of prior research. This is undoubtedly a severe test for China's young solid-state ballistic missile development team.

In the demonstration and design of the overall scheme, the designers have encountered four major problems, including how to choose the test method of the underwater mobile launch technology of the missile, what kind of launch method to choose, the test procedure of the selected missile, and the solution to the problems of the missile body, two-stage power unit and guidance system.

But such a problem, even in the era of poverty and whiteness, it is not difficult to live in the Chinese people who have always been rich in creativity!

The Julang R&D team, with Huang Weilu, an expert in the control system, as the chief designer of the submarine missile, lasted nearly ten years and laid a solid foundation for the birth of the Julang-1.

After Yang Weiping took office as the director of the Commission of Science, Technology and Industry for National Defense, Qian Lao, who had already obtained the true scriptures from the hands of Yang Da scientists, drew on the mature technology of the WS6H1 core machine, and carried out a series of technical breakthroughs and breakthroughs in the research of solid rocket engines and liquid rocket engines in China.

In view of the fact that China has successfully applied a large number of new high-temperature and high-strength aerospace materials, coupled with the GTH79 series solid rocket engines and YTH79 series liquid rocket engines successfully developed by a group of aerospace experts such as Qian Lao, Yang Weiping provided Chief Designer Huang Weilu with a new submarine missile design scheme, which adopts the current international unprecedented combination of first-class solid and two-stage liquid structure, as well as the design concept of free orbit, and overturns the original design scheme of Julang No. 1.

The new Julang-1 submarine-launched ballistic missile has a two-stage structure, a first-class solid, a first-class liquid, a maximum range of 8,500 kilometers, a mass of 21 tons, and can carry eight 250,000-ton split-guided thermonuclear warheads, using strapdown inertial, ballistic computers, laser gyroscopes, and astronomical navigation guidance systems, with a circumferential deviation rate of 40 meters, and the launch platform is submarine-launched, and the target of the strike is Alaska, the United States.

After handing over the new design plan to Chief Designer Huang Weilu, Yang Weiping was very irresponsible and took up the role of the shopkeeper, and except for occasionally making a few phone calls to care about Chief Huang's health, he rarely interfered in the development of the new Julang-1 missile.

In Yang Weiping's mind, it is estimated that the first test launch of the new Julang-1 type will not be possible until the completion of the improvement and supporting project of the 092 summer-class nuclear submarine.

In addition to upgrading the technology of the original military pressurized water reactor, it is also necessary to replace it with a new high-precision seven-bladed propeller that is processed at one time. In addition, the overall silent design and marine electrical design should be improved.

It can be said that except for the hull that has not been moved, everything else has to be moved, and there is no one who has two years in a year, and it cannot be completed at all.

Obviously, Yang Weiping seems to have forgotten that our country also has a Type 031 ballistic missile conventionally powered submarine.

The "G-class" (031) ballistic missile conventional submarine, commissioned in 1966, was built only one, with a board number 200, mainly for training purposes. It is possible to launch 2 CSS-N-1 missiles (the Chinese version of the Soviet SS-N-2 Styx tactical ship-to-ship missile).

This submarine, which has a surface speed of 17 knots and an underwater speed of 13 knots, is of course an old and backward equipment that must be eliminated in Yang Weiping's eyes. However, if it is used as a submarine-launched test launch platform, it is still competent enough.

"Chai Lao, what is the effect of the test launch, and does the range meet the design requirements?" Yang Weiping asked with great concern. Because he knows very well that the launch of submarine-launched missiles under the water is a hurdle, and whether or not they can reach the design range is a major hurdle.

"The design standard has been fully met!" Chai Shufan's eyes were full of excitement, and he nodded again and again and replied: "For this test launch, I specially arranged for the 718 Project ships headed by the 'Yuanwang' to cooperate with the monitoring throughout the whole process, and this time is not only the test launch of the Julang-1 missile, but also the inspection of the 718 Project ships in the bomb landing area to investigate, measure, select points, sweep, alert, missile flight measurement, observation, warhead salvage, meteorological observation and forecasting and other tasks!"

"Damn!" Yang Weiping couldn't help but burst into foul language, and shouted very dissatisfiedly: "Chai Lao, why didn't you notify me to participate in such an important mission? This is the first time that our ocean-going fleet has sailed out of the first island chain and into the Pacific Ocean. ”

"It is precisely because this is the first time that the first island chain has been breached, and there may be unpredictable risks, that we have not informed you. Chai Shufan said quite seriously: "Because, your safety is related to the future of China's national defense industry, and Huaxia can do without me Chai Shufan, but it can't do without you, Director Yang! Cheng Yun, Chen Jinghua, and other veteran comrades all unanimously agreed that if we told you about this test-launch mission, with your character, you would definitely ask to go to sea with the fleet, so we unanimously decided not to tell you first. ”

Feeling the deep concern of these old leaders, Yang Weiping's heart rose with a warm current of emotion, and the previous unhappiness had long since disappeared, and he sighed with emotion and said: "Old Chai Lao, your words are really serious. Could it be that without me, Yang Weiping, our country's national defense work would not have been able to be carried out? You keep saying this, how can I really be embarrassed and ashamed!"
