The next day, Bohai Shipyard, Longgang District, Jinxi City, Liaoning Province.
The area of Jinxi City in this plane is roughly equivalent to Chaoyang City and Huludao City in the original time and space combined.
The Jinxi Port here is a natural ice-free port in northern China and can currently berth ships of less than 50,000 tons.
As one of China's fifteen five-star shipbuilding bases, Bohai Shipyard is located on the Hulu Peninsula of this city, adjacent to Jinxi Port.
At this time, in the No. 3 dock of the shipyard, a battleship was being refitted.
Anyone familiar with the Chinese Navy can recognize it at a glance.
This is the world's first super-dreadnought-class battleship "Fuxi class".
At the same time, it is also the most produced battleship in the world.
It is produced by three countries, China and the United States.
It has built up to 24 ships and equipped the navies of 5 countries in total.
This does not include its base.
Other models with magic modification and enlargement.
In addition, it has achieved quite astonishing results in previous naval battles.
Therefore, this class of battleship is very famous in the world and is hailed as a "standard battleship" by the U.S.
Navy.
Of course, things like warships also have a shelf life.
The waves behind the Yangtze River push the waves ahead, and no matter how superior a warship is, it is impossible to remain outstanding.
No matter how good the Fuxi class is, it is only a product before the First World War.
What's more, the period before and after World War I was the fastest time for ship technology to be updated in history.
A warship is often outdated just after it is launched, which is about the same speed as later generations of computers.
When the time entered the 1930s, the Fuxi class had indeed fallen behind.
Although its hull design was still very advanced, its tonnage was already too small after all.
Most importantly, its 360mm main gun was far behind the times.
In the current navies of several top powers, battleships with more powerful firepower are everywhere.
The main guns do not exceed 400 mm, and they are embarrassed to say hello to others when they go out.
However, when the Fuxi class was modified in the second batch of design version 2.0, future upgrades and modifications were taken into consideration.
For example, in terms of the hull structure, the size and load-bearing capacity of the turret seat, and the load of the bomb lifting system, margins are left during the design.
By the way, the drawings sold to the United States and Germany are all the first batch of Fuxi-class version 1.0, with very small design margins.
As for whether the United States and Germany will improve the design, it doesn't concern China.
As early as World War I, the Chinese Navy had a plan to upgrade the Fuxi class.
It was just because there was no time during the war.
After World War I, there was no need to worry.
It had to be improved anyway.
It was better to wait until the relevant subsystems were improved. .
Until last year, Wen Desi felt that various related technologies were already relatively powerful, and the subsystems were almost ready.
Only then did the "Fuxi-class" transformation plan officially start.
Like the large fire support ships, this is also based on the consideration of stimulating domestic demand.
Throughout the ages, increasing armaments construction has been an effective means to stimulate domestic demand and expand the internal market.
For example, the three virtues of the original time and space, how they got rid of the economic crisis, must vigorously increase the military build-up, which is one of the methods.
Of course, Mustache borrowed money to play, so in 1939, when the debt was about to expire, he couldn't fight even if he didn't want to.
China on this level is completely different.
It is very rich, but it just wants to distribute the money.
There is no need to borrow money to support the facade.
The Fuxi-class transformation plan is a big move.
The weapon system, power system, electronic system, and armor must be modified.

Basically, except for the hull, everything else must be improved and upgraded.
However, because future improvements were taken into consideration during the initial design, the design redundancy is very large, and many parts adopt modular designs, such as the weapon system, so it is much simpler than the improvement of "Ellie".
The ship under construction at the Bohai Shipyard is the third ship of the Fuxi class and the first "Houyi" in the 2.0 Chinese-made version.
At this time, the Houyi had been disemboweled, and all weapon systems and superstructures had been demolished.
Li Ang was standing on the edge of the dock and watching as a huge gantry crane was lifting a gas turbine and sending it to the power cabin of the ship's hull.
At this time, the Houyi's power cabin was empty, and the original oil-fired boilers and steam turbines had been dismantled.
After inspecting the Dalian Shipyard yesterday, he took a navy plane and flew here early this morning.
Comrade Li Ang now has three gold stars on his shoulder straps.
Yes, he is already a lieutenant general.
In September 1923, he was transferred from the Pacific Task Force to the Naval Command and served as the director of the Naval Equipment Bureau; in March 1926, he was transferred to the commander of Qingdao Base; in May 1928, he was promoted to lieutenant general and served as the commander of the Nanyang Squadron.
In January this year, he returned to the Naval Command and served as Deputy Chief of Naval Staff and Director of the Equipment Bureau.
Bo Shipbuilding General Manager Jin Longyu introduced with pride: "Mr.
Li, the Houyi reconstruction project involves more than a hundred projects, the most important of which are the upgrade of the main gun, power system and armor.
The original Some triple-mounted 360mm main guns have been replaced with twin-mounted 420mm main guns, and the power system needs to be From steam turbines to gas turbines, the original main armor belt needs to be upgraded from single-layer armor to composite armor, and the armor at other locations must also be thickened.
In addition, the computer system, radar, and fire control systems must be upgraded, and the secondary guns and weapons must be upgraded.
Guns and bow sonar, adding mine protection protrusions, modifying underwater shapes, etc.”
Li Ang asked: "I have seen the modification plan.
It says that after these modifications, its standard displacement will increase to about 40,000 tons.
Is that true?"
"Yes, the increase in tons is mainly due to the widening of the mine protection protrusion.
The hull is 5 meters wider than before, and the hull has also undergone some modifications.
In addition, the armor has been thickened.
However, after such modifications, its The combat effectiveness will be greatly improved, and the added weight is completely worth it.”
"How long will it take for the Houyi's renovation project to be completed?"
"Mr.
Li, the work in our shipyard will be completed in about 11 months.
Including system testing, it will take about 3 months," Bo Shipbuilding General Manager Jin Longyu replied.
"Yeah."
Li Ang calculated in his mind that it would take more than a year and a half to complete the transformation and testing of the shipyard, plus the running-in of the crew, practicing new tactics, writing maintenance manuals, etc., until a complete combat effectiveness is formed.
By two years, this speed was already quite fast in peacetime.
If it were done abroad, a major change like this would take at least three years.
The reason why China is so fast is because it has more advanced and more automated equipment.
"Hey, it's a pity that we haven't built any new battleships in recent years.
We have all built them for others," Jin Longyu said with some regret.
"Yes."
Li Ang, a BB guy, also sighed with regret.
This is the resolution of the central government.
Wen Desi has made it clear at the naval work conference that there will definitely be no major construction tasks in the next few years, and Li Ang has no choice.
However, although there is no major construction, there are still renovation tasks.
The Chinese Navy currently has 24 super-dreadnought-class battleships, including eight Fuxi-class ships, Fuxi, Nuwa, Houyi, Chiyou, Xuanyuan, Shennong, Dayu and Kuafu, and four Sunwu-class ships, Sunwu , Jiang Shang, Sun Bin, Wu Qi, four Li Jing-class ships Li Jing, Tian Ranju, Wei Liao, and Huang Shigong, four Yue Fei-class ships Yue Fei, Qi Jiguang, Huo Qubing, and Wei Qing, and two Qinling-class ships Qin Ling and Taihang.
There are also two trophy ships, one is the "Fühao" as a technical verification ship, the former "Andrea Doria" of the Italian Navy, nicknamed "Ellie", and the other is the "Five" as a training ship "Zheng He" was formerly the "United Empire" of the Austro-Hungarian Navy.
There was originally a Hanoi, but after the Japanese revolution and joining the People's Revolutionary League, China returned this obsolete quasi-dauntless ship to the Japanese People's Navy.
Among these 24 battleships, the two Qinling-class ships were originally weakened versions for emergency use because the docks were not enough.
The design itself had little margin, and the room for transformation and improvement was very small, so they were not included in the transformation. plan.
Starting this year, the two Qinling-class ships have been transferred to the second line and served as training ships.

The first batch of Fuxi-class battleships, Fuxi and Nuwa, were in version 1.0, so it was very troublesome to modify them.
The most important thing was that they were attacked by Italian torpedo boats during the Mediterranean war and were hit by multiple rounds.
Although the torpedoes barely managed to sink due to their good underwater defense, their hulls were also seriously damaged, so after returning to China for repairs, they were also placed on the second line.
More importantly, both battleships were built in the United States.
The quality of the American steel at that time was not very good, which made their natural foundation much weaker than the domestically produced sister ships of the same class.
Therefore, these two battleships did not join the transformation plan.
According to Wen Desi's idea, Fuxi and Nuwa were the first batch of China's major battleships to be built.
They had great historical significance, and they were also ships with outstanding merits, so they were retired.
They will not be demolished later, but will be converted into battleship museums.
Wen Desi planned to put one in Qingdao and one in Shanghai.
Two Qinling-class ships were also converted into battleship museums, one for Guangzhou and one for Fuzhou.
In addition to these four ships, the remaining twenty battleships must be modified.
The two trophy ships, Ai Li and Zheng He, are both second-line battleships.
Ai Li is a technology verification ship.
It is its job to carry out magical modifications to verify various new technologies, so I won’t go into details here.
The Zheng He is a training ship and there will be no major changes if it is modified.
The other eighteen battleships will need to be renovated and upgraded, and their changes will be relatively large.
The power system will definitely need to be changed, and the armor will also need to be improved.
The first batch is the remaining six Fuxi-class ships.
Their modifications are the largest, even the weapon systems have to be modified.
It was only after General Li Ang took office that he realized that as the director of equipment, he would be very busy in the past few years.
Although there were no large-scale construction tasks of battleships, there were still a lot of magic modification tasks for various ships and the construction of new ships.
The largest one is called the "General Merchant Marine Plan".
As the name suggests, it is a plan that allows merchant ships to be easily transformed into warships.
Converting merchant ships into warships is not a strange thing.
It has happened since ancient times.
During World War I, a large number of merchant ships were converted into warships by various countries.
However, it was China that started to formally form it into a country's mandatory norm.
This plan started in the late stages of World War I and was so large that it involved almost all high-speed merchant ships.
In 1916, China introduced a new series of ship standards, formulated a series of new standards, and established the "Ship Code Committee", which stipulated that all new merchant ships ordered by domestic users with a speed of more than 13 knots must pass the design and construction Supervision and review by the "Ship Rules Committee".
Including the general modification design of escort aircraft carriers for high-speed large merchant ships such as high-speed passenger ships, ro-ro ships, and container ships; the general modification design of auxiliary cruisers for medium-sized merchant ships; and the general modification design of auxiliary anti-submarine vessels for small merchant ships such as high-speed fishing boats.
The first requirement of this plan for commercial ships is standardization and modularization.
Each subsystem can be easily replaced and disassembled, and sufficient room for improvement is left during design.
These ships are civilian ships in peacetime, no different from normal civilian ships, but once a war breaks out and they need to participate in the war, they can be transformed into warships with only a simple modification.
However, not all types of merchant ships are suitable for conversion into warships.
It is of little significance to convert low-speed merchant ships with a speed of less than 13 knots.
There are also some special-purpose merchant ships such as refrigeration ships and liquid natural gas carriers, whose hull structures are inherently unsuitable.
So this category is not included in this plan and is not restricted.
Of course, the performance of this kind of civilian version of the warship is definitely not as good as the genuine warship, but it can't stand up to the large number.
This is the Navy’s version of People’s War To the west of the Bohai Shipyard, in a remote corner away from the main factory area, there is a very long building that extends from the sea to the mountain more than 200 meters away.
This camouflage-painted building is about 40 meters high and 50 meters wide.
The sea side extends into the sea and the mountain side is embedded in the mountain.
The building is heavily guarded, with a security zone of more than 300 meters.
Moreover, this building is very strange, with only a few doors on the wall and a few rows of sparse transom windows.
But if you walk inside, you will find that this very large building is actually just a shell.
Free novels bring you joy and joy ---> storyskyline.net
It is empty and has nothing inside.
Well, it's not really like there's nothing there.
There are a lot of electric lights and ventilation fans inside, and there are also escalators and platforms on the walls.
Of course, the most important thing is in the center of the ground.
This is a 42-meter-wide waterway.
This straight waterway is about 300 meters long, with one end leading to the sea and the other end leading to the interior of the mountain.
There are two gates at both ends of the waterway, both of which are tightly closed at this time, especially the two steel gates embedded in the mountain, which look quite thick at first glance.
Yes, this building is just a cover.
Its biggest function is to cover up the waterway leading into the mountain.
So it doesn't matter what's inside the mountain, it's just a small shipyard.
Calculated based on its shipyard, it can only build 20,000-ton ships at most, which is indeed not considered large in China today.
This mountain is not big, only more than two hundred meters high, covering an area of more than ten square kilometers, and has no name.
During the planning of the Bohai Shipyard, it and several other nearby hills were included and renamed "Calabash Mountain".
Afterwards, China sent a large number of construction teams.
It took seven years to hollow out the hills in the Bochuan site and build many buildings inside, especially Hulu Mountain, whose entire mountainside was dug out.
There are large and small holes, the largest one is 40 meters high, about 500 meters long, about 200 meters wide, covering an area of 100,000 square meters, and there are four large and small docks inside.
Normal people know that building a shipyard in the middle of a mountain is undoubtedly a very, very time-consuming and labor-intensive matter.
As for why it took so much effort to hollow out the mountain and build this shipyard inside.
The reason is very simple, because this is the final assembly plant for nuclear-powered submarines.
This is China's first and currently only final assembly plant for nuclear-powered submarines.
In fact, this inconspicuous place is the real center of gravity of the Bohai Shipyard, although the area of this area is less than one-tenth of the Bohai Shipyard area.
At this time, the four docks are full, and each has a teardrop-shaped submarine.
From the appearance, it can be seen that they are all of the same model.
The two docks in the east are still under construction of their hulls, and the two in the west are still under construction.
It seems almost done.
"Mr.
Li, the outfitting work of the two Type 912 boats No. 1 and 2 has entered the final stage and will be completed by the end of the month.
Sea trials of the No. 3 and No. 4 boats will begin next month and will be completed in July this year.
The hull will be built and the outfitting work will be completed around the end of next year," Jin Longyu introduced next to him.
"Well, how is the situation of Type 911 now?"
Li Ang nodded.
This is not the first time he has been here.
Originally, conventional submarines were built here.
When he first came to inspect as director of the Equipment Bureau, the product here was the Type 908 "Walrus-class" ocean-going transport submarine, a large submarine with a water displacement of 15,000 tons.
It was mainly responsible for transporting "humanitarian relief supplies."
Jin Longyu proudly replied: "The situation of Type 911 is very stable and it has been running smoothly for four years.
Engineering ships No. 9000 and 9001 have also been running smoothly for six years."
The Type 911 and No. 9000 engineering ships they are talking about are experimental models.
The No. 9000 and No. 9001 engineering ships are the earliest nuclear power technology verification ships.
The Type 911 is an experimental nuclear-powered submarine and the world's first nuclear submarine.
The two Type 912 submarines that are about to be completed are the first nuclear-powered submarines officially commissioned by the Chinese Navy.
Type 912 is named "Beluga Class" in the Navy.
They use the fourth-generation reactor gas-cooled fast reactor.
The gas-cooled fast reactor is the most cost-effective fourth-generation reactor.
It can achieve fuel value-added and has good inherent properties.

Security Features.
Because it is a value-added reactor, its uranium fuel utilization rate can reach more than 90%, which is about 200 times that of a pressurized water reactor.
After the Beluga class is built, if there are no accidents, it will not need to change the fuel for life.
Before they started construction, two experimental ships using fourth-generation reactors disguised as merchant ships had been operating at sea for almost four years, and two Type 911s had been operating around the world for almost two years, proving the effectiveness of fourth-generation reactors.
