Traveling through the sword to engage in military industry.

On October 53, 10, the Qin-class nuclear attack submarine No. 1 was launched as scheduled. Only the power system and conventional navigation system maintained normal functions. No. 001, which could simply run naked, basically did not find any major problems in the initial tests. Even the diving depth and speed tests were beyond expectations.

The power is abundant to the point of bursting. After getting familiar with its simple use, I can even speed over 30 knots underwater and still feel like there is still plenty of power to spare!

If he hadn't been afraid of problems, the first captain Liu Wensheng felt that he could go even higher. However, he was afraid that the submarine's hull would have problems at high speeds. After all, it was the first nuclear submarine, and no one dared to test it to the limit.

30 knots was the design goal, and it was achieved easily. After more than 30 hours of high-speed sailing tests, there was no pressure at all. After being launched from Dalyan, the No. 001 nuclear submarine went south along the Yellow Sea and directly bypassed the Miyako Strait to enter the Pacific Ocean. The next diving depth test started from 200 meters, and the test was carried out at high speed underwater for one hour every 50 meters. It completed the 400-meter diving depth test in sequence and then returned to the base.

The operation has been very stable. The reactor named Dawn No. 20 (SG-) is very adaptable to high-speed and deep-diving static tests. The start and stop switching is slightly slower than that of a diesel engine, but it is much faster than a heavy oil steam turbine.

Nuclear reactor core components
According to monitoring data from various sources, the Shuguang-90 reactor is very stable, almost perfectly matching the expected technical parameter indicators. The matching steam turbine drives the propeller through the reducer very smoothly. Except for its low efficiency, the 2MW thermal power output to the propeller is only 14.7 horsepower (5MW). Another part of the steam is sent to a 22MW steam turbine generator to power the submarine. The energy conversion efficiency of this first-generation product is not too high, less than %, but it is currently sufficient for submarines of to tons.

According to Professor Wu and his colleagues' calculations, under current technical conditions, after further optimizing the design and improving the processing technology, the efficiency of steam thermal energy and mechanical energy conversion can be increased to 30%-35%, and the shaft power driving the propeller is expected to increase to between 3 horsepower and 6 horsepower!
This proves that there is huge room for improvement in the first generation of reactors! According to this shaft power technology, if we need to design a nuclear-powered aircraft carrier of about 5 to 6 tons in the future, we can use at most four Shuguang-4 reactors.

Similarly, if this Dawn-8000 reactor is used on a large destroyer, a destroyer with a full load displacement of about 2 tons only needs two Dawn- reactors to drive it. Even a -ton destroyer can be easily dealt with after optimizing and increasing the reactor power.

Although the Rogue Eagle's nuclear-powered destroyer was only a flash in the pan in the main world's historical time and space before switching back to conventional power, that was because the gentlemen in Congress thought it was too expensive!

Moreover, with so many ships being fully nuclear-powered, there are only two or three nuclear power manufacturers that have made a fortune, and the benefits are not evenly distributed.

According to the information Ren Zhong obtained from the main world, Dongda lacks the support of a large number of overseas bases. If it wants to carry out global military activities, the demand for nuclear power is far more urgent than that of the Rogue Eagle, so it is very necessary to build one or two all-nuclear-powered hybrid fleets.

According to the main world standards and future conflict handling capabilities, a task force that can independently carry out overseas missions will have an aircraft carrier as the base, one or two amphibious assault ships, 4-6 large destroyers, 1 comprehensive supply ship, and 2-3 attack nuclear submarines.

按照常规中型航母标配，任重期望第一艘航母能装载正在研究的F-4鬼怪式舰载机36架，预警机2架，直升飞机4机，电子战机2架的规模。而两栖攻击舰要有运载1000人兵力，30架各种型号直升飞机，40辆主战坦克和40辆轻型装甲车和12门以上105自行榴弹炮或者122毫米火箭炮规模。

With such a task force, basically, except for the five big gangsters, there are few countries in the world that can compete with it. In this way, in case of any emergency, our task force can respond globally at any time!

Basically, you can accomplish your mission in any hot spot on the planet in two weeks!
A fully nuclear-powered fleet is Ren Zhong’s crazy dream in the main world. Now the success of the first-generation nuclear-powered submarine Qin will definitely stimulate this dream to become a reality.

After all, price is not a big problem for Ren Zhong now. More than a dozen nuclear reactors, even according to the current prices, the cost of each reactor may be more than 5000 million. But it is not important to Ren Zhong. He can support the cost of the reactor with the economic benefits generated within the Liming Research Institute system!
At most, it is only more than 6 million. A fully nuclear-powered fleet can run for 10 years before the fuel needs to be replaced! Even if there is only one such fleet floating on the ocean of Blue Star, it is a heavy comprehensive national strength!

Today, the keel laying of the first generation Dongting Lake-class amphibious assault ship, which was developed according to the general functional architecture and specifications of the Mistral-class amphibious assault ship, has begun and it will be launched in less than two years. In terms of power, the current heavy plan is to have two improved Dawn-1 reactors!
As a pilot test ship for nuclear-powered aircraft carriers, Dongtinghu has undertaken many preliminary verification tasks for aircraft carriers. It even has to take off fighter jets on the deck. It can be said that in addition to the landing of fighter jets due to the strength and length of the runway, other functions of the aircraft carrier need to be practiced, including the steam catapult device!

However, all of these are still under intensive development. Back to reality, after more than a month of sea trials, the No. 001 nuclear submarine returned to the Dalian Shipyard for weapon equipment. After several days of assembly, the first generation of 533mm heavy torpedo JK-1 torpedo, code-named Jing Ke, was successfully matched with the Qin class!

In the first secret sea test, the Type 001 nuclear submarine successfully destroyed a 3000-ton old cargo ship with one shot!
The success of this exercise means that the torpedo attack capability has been formed. From discovering the target to launching the torpedo, the automatic homing of the torpedo and finally hitting the target ship to directly destroy it, the entire process was done in one go and was very smooth, fully realizing the original design indicators of this torpedo.

Immediately afterwards, the nuclear submarine's avionics system was successfully tested and accepted, and was connected to the Vostok satellite communication and positioning system. During the field test, after diving, through two floating beacons at a depth of 20 meters, the No. 001 command module achieved accurate offshore positioning and real-time communication with the headquarters!

Although floating beacons are a great damage to the stealth of submarines, they are not directly exposed on the water surface. Instead, they are about 20 meters underwater. This depth has avoided almost all sea surface targets and cannot be detected through optical observations.

The draft depth of a 9-ton giant ship is generally around 3 meters, 11.3 tons is 14 meters, 17.3 tons is around 19.1 meters, 20.4 tons is meters, tons is around meters, and tons is around meters.

For the current world of Sword and Fairy, giant ships of 30 tons are still in their infancy. Such floating beacons can perfectly avoid interference from transport fleets.

The first generation of nuclear submarines was thus completed!

On New Year's Day of 54, as planned, the Qin-class ship quietly left its home port after comprehensive inspections and replenishment and began its first global voyage!
Ma Yingwei never dreamed that he, a man engaged in agriculture, would one day participate in the first global combat readiness training with the first nuclear submarine in history.

In the precious space on the No. 001 submarine, a "test field" 12 meters long and 5 meters wide was reserved, which is Ma Yingwei's "combat position". During this long voyage, Ma Yingwei's task is to guard this test field and provide fresh vegetables for the officers and soldiers on the submarine!

Thanks to the abundant power supply of nuclear submarines, sufficient oxygen and fresh water, or carbon dioxide, can be obtained by electrolyzing seawater, which is completely different from conventional submarines.

Coupled with the full-spectrum LED lighting that Ren Zhong brought from the main world, the soil is excellent organic soil, and there is sufficient organic fertilizer. It can be said that Ma Yingwei has the best conditions that a vegetable farmer dreams of!
Therefore, Ma Yingwei was determined to make a career in this small space. Of course, in addition to providing fresh vegetables for his submarine colleagues, Ma Yingwei also had an experimental task to study the growth of vegetables in a submarine environment.

His experimental field is now divided into four areas. There are semi-vegetables transplanted from outside, which are expected to be harvested in three to five days; some need ten days to mature, some have just sprouted, and will take about twenty days to mature, and some are seeds that have just been planted.
The other is an automatic bean sprout machine. According to the design standards, this automatic bean sprout machine with technology from the main world can produce up to 100 kilograms of bean sprouts a day, no matter if they are soybean sprouts, mung bean sprouts, or various black bean sprouts, as long as they can sprout.

When vegetables are insufficient, bean sprouts are used as fresh vegetables to supplement the meals of the officers and soldiers on the submarine.

Since the Type 001 nuclear submarine uses a 5MW electric drive and is equipped with an air purification system, it no longer has the dilemma of carefully calculating the air supply of conventional submarines. Even if you eat too many bean sprouts and get bloated, it will not have much impact on the submarine. With sufficient oxygen and fresh water supply, the air on the submarine can be adjusted in composition at any time as needed, including the adjustment of the air conditioning temperature.

The widespread use of electric hot pots has also meant that conventional submarine canned foods and refrigerated pre-prepared meals have not become mainstream in the new generation of nuclear submarines.

Of course, Liu Wensheng and his colleagues now have no idea that conventional submarines have all these troubles.

However, Liu Wensheng, a new generation of submarine captains who were trained through rotation on a number of domestic surface ships, knows that when he was working on destroyers before, the food configuration was not as large as that on submarines today. There was even a special vegetable grower to ensure that everyone could have a meal of fresh vegetables every few days.

However, there is not only a planting expert like Ma Yingwei on the submarine, but also two medical experts!

Their mission is to conduct physical examinations for the officers and soldiers on the submarine every day and study the physical and psychological effects of long-term voyages on the officers and soldiers.

For ordinary people, these things are simply unthinkable.

But Ren Zhong knew that nuclear submarines had a great mission and would be the real security pillar of Southeast University in the future.

Therefore, it is not only necessary to solve the problem of food for everyone, but also the physical and mental health problems of everyone. Otherwise, a submarine mission may take dozens of days to dive under the sea, and the weapons carried are powerful weapons of mass destruction. Once these controllers have psychological problems, it will cause very heavy losses to the country.

Therefore, in order to prepare for a rainy day, taking advantage of this global submarine voyage, Ren Zhong also asked the medical department to do a good job in monitoring the physical and mental health of all officers and soldiers on the ship.

Two young doctors, Wu Ze and Liang Yongding, were rigorously selected to undertake this special medical research task.

In this way, a total of 107 people on the ship, carrying the great expectations of the top leaders of the University of Tokyo, issued the first report after 30 hours of diving.

"Safe passage through the Miyako Strait"

The command had long anticipated such news. The current submarine search technology and the number of underwater sonar installations are far less tight than the dragnet of the main world and time and space.

According to the current noise level of the Type 001 nuclear submarine, it has been reduced to 110 decibels underwater, which is very close to the seabed noise level of 95 decibels. Ordinary sonar can hardly detect it from a distance without warning.

The Miyako Strait is about 200 kilometers wide. Although the Rogue Eagle now has a small military base on Miyako Island to conduct reconnaissance and surveillance of the ocean and sky, it has not reached the level of covering everything on the seabed with sonar.

So for the command center, since they were not discovered the first time they crossed the Ryukyu Islands and entered the Pacific Ocean, it seemed normal for them to pass through the Miyako Strait now.

More than 30 hours later, when Liu Wensheng arrived near Iwo Jima, he repeatedly confirmed with passive sonar that there were no ships or boats nearby. Then the submarine slowly surfaced and, close to the water surface, used a periscope to photograph Mount Suribachi on Iwo Jima!
This wild mountain, which became famous for the bloody battle of the Rogue Eagle during World War II, looked like a pile of cow dung in the periscope, which disappointed Liu Wensheng greatly. However, this was the first target for his global diving this time.

Mount Suribachi, Iwo Jima
So around Mount Suribachi, Liu Wensheng asked the part-time photographer on the submarine to take pictures of Mount Suribachi from three directions to show that he had been there.

Next, the nuclear submarine No. 001 dived again to a depth of 400 meters and began to sail towards the next target. About 80 hours later, it arrived at another famous island - Midway Island!

This time, Liu Wensheng also checked in at the coral reef from a distance through a periscope and then left.

After destroying the main force of the Japanese Combined Fleet, Rogue Eagle achieved a turning point in the Pacific War of World War II here!
But now, Rogue Eagle no longer values ​​this place. It has cancelled regular flights to the island since 1950. The navy withdrew in the same year, leaving only some garrison troops on the island. The originally large-scale submarines and naval squadrons are no longer deployed on this island.

Therefore, the Rogue Eagles' remaining troops knew nothing about Liu Wensheng and his group's "visit"! (End of this chapter)
