Jiangnan Shipyard has a long history. Its predecessor was the Jiangnan Machinery Manufacturing Administration, which was founded in the fourth year of Tongzhi in the Qing Dynasty (i.e. 1865). In the early 1950s, it was renamed Jiangnan Manufacturing Factory.

As the 'No. 1 factory in China', Jiangnan Shipyard has witnessed the vicissitudes of China for a century and a half. After its birth, it has created countless firsts: it produced China's first lathe and built China's first steam-propelled ship.

The warship 'Huiji' and the first armored warship 'Jinou' developed China's first rifle, first steel cannon, first pound of smokeless gunpowder, and refined China's first furnace of steel....

..

By the 1890s, Jiangnan Manufacturing Factory was the most technologically advanced and well-equipped machine factory in China and even East Asia.

Unfortunately, with the turbulence of the country and the shattering of mountains and rivers, the shipyard felt unspeakable sadness, especially the massive destruction before the retreat of the national army in 1949, which left the Jiangnan Shipyard in a state of devastation and dilapidation.

After the founding of New China, Jiangnan Manufacturing Factory finally regained new vitality, quickly resumed production, and continued to create many "Chinese Firsts": it built China's first submarine, the first 10,000-ton hydraulic press, and built China's first

It has produced the space survey ships 'Yuanwang 1', 'Yuanwang 2' and the first large-scale ocean survey ship 'Xiangyanhong 10', etc., as well as built China's first liquefied petroleum gas carrier (lpg).

Aircraft carrier No. 003, also China's first nuclear-powered aircraft carrier, was built at Jiangnan Shipyard.

In recent years, as large-scale ships independently developed by China have been continuously launched and entered the navy, especially the launch of the Type 002 aircraft carrier, its emergence marks that the Chinese Navy will reach the world's advanced level in all aspects of surface main battleships.

In China, large warships are generally designed and built in Dalian, Jiangnan, and Hudong shipyards, while submarines are Bo ships, and Huangpu Shipyard has made many achievements in the design of military ships and frigates.

At present, China's shipbuilding industry is at the world's advanced level, and its scale is the largest in the world. It builds warships very quickly. From cutting the first steel plate to launching the warship, it only takes about 600 days for a frigate and 700-800 days for a destroyer.

, the aircraft carrier takes about 1,400 days.

After landing at a military airport in Shanghai, Liu Yichen took a military transport helicopter and arrived at the Jiangnan Shipyard. Looking at the huge Jiangnan Shipyard, Liu Yichen was also deeply shocked.

The entire Jiangnan construction plant covers an area of ​​15,000 acres in total, with a shoreline length of about 3,800 meters. Looking down from the helicopter, you can see four large docks and 17 outfitting docks, which are used to build both civilian ships and warships.

He even saw that one Type 055 10,000-ton large-scale drive was almost completed, and at the same time, three Type 055 10,000-ton large-scale drive were under construction.

Looking at the steel behemoths under construction, Liu Yichen was filled with passion, because it was such steel behemoths that formed the Great Wall of Steel, guarding the Chinese nation and intimidating those careerists.

The transport helicopter stopped in an area and parked on the apron, and Liu Yichen got off the helicopter.

"Academician Liu, please make a trip!" An old man about sixty years old came over in person.

"Director Hu, you're welcome! It's an honor for me to be able to contribute to China's aircraft carrier cause!" Liu Yichen said modestly.

"Let's go to the base!" Director Hu said with a smile, taking Liu Yichen to a dock where the keel had already been laid.

Liu Yichen looked at the model of the aircraft carrier. This was also an aircraft carrier under construction. When completed, it would completely use electromagnetic ejection instead of deck flyover or steam ejection.

Such a steel behemoth has a standard displacement of 101,600 tons, a full load displacement of 112,000 tons, a length of 337 meters, a width of 77 meters (deck), and 41 meters (waterline). Its speed exceeds 30 knots, and its power system is 2

The nuclear reactor has a ship crew of 1,150 and a flight group of 600. It can carry a standard 75 aircraft of various types and a maximum of 90 carrier-based aircraft.

Many advanced technologies used in the previous two aircraft carriers will be applied to this nuclear-powered aircraft carrier. At the same time, this aircraft carrier has also conducted a large number of technological experiments.

The antennas of various phased radars, satellite communications, data transmission links, electronic warfare systems and joint precision approach and landing systems on the ship are integrated into the bridge structure or placed on the lightweight mast on the top of the bridge.

"Seat!?" Liu Yichen looked at a meticulously dressed old man in his sixties and was quite surprised, because this man is arguably the most well-known military analyst in the country and has been working in the field of national defense science popularization for 20 years.

Over the years, his presence can be seen in the establishment and development of various military columns.

Even though he was controversial for saying that smog can prevent laser weapons and kelp can prevent submarines, etc., it still couldn't stop the people from liking him. And as time went by, he had more and more fans, so that later he suddenly became popular among the public.

After disappearing from the public eye, there are always little oranges who miss and call out every once in a while.

He did not expect that there would be a bureau seat in this aircraft carrier base.

However, when I think about it, it is not impossible for this person who has studied aircraft carriers all his life to join the aircraft carrier project.

In the base, scientific researchers are busy one after another. Even if they complete the design work and enter the construction work, the experts have not slacked off at all, because during the construction of aircraft carriers for several years, this kind of thing will always happen.

That kind of problem.

"Academician Liu, I invite you to come here this time. There are two aspects of work that require your support. One is about the command and control central system, which needs your help. The second thing is that you need to help with the supercomputer simulation of the aircraft carrier."

Director Hu talked about the task of inviting Liu Yichen over this time.

Liu Yichen was slightly surprised, but he didn't say much. As for the joint combat command system, Liu Yichen is an expert in this field. He optimized or designed the combat command systems on the Liaoning and Qilu ships, and they have been highly praised so far.

Good reviews.

Although the No. 003 aircraft carrier is under construction, a lot of work has actually been completed. Obviously, the military is not very confident about the command system, so it asked him to check it.

As for supercomputing simulation, obviously during the design stage, many supercomputing simulations must be carried out. Now we are doing it again, but the purpose is to find and solve problems as much as possible at this stage, instead of waiting until the construction is completed and various problems arise.

All kinds of questions.

"I won't be here for long. The supercomputing simulation will be carried out at the Supercomputing Center of Kowloon University." Liu Yichen said.

"Understood, understood! We can't thank Academician Liu enough for taking the time to come here!" Director Hu said with a smile.

Liu Yichen came to a conference room and began to look at the command and combat system. This command and combat system was based on the command and combat system of the Qilu ship and modified according to the actual needs of the No. 003 aircraft carrier.

There are naval experts who describe the basic situation of the Type 003 aircraft carrier, the composition of the entire fleet, and what functions it needs to have.

Liu Yichen listened very carefully.

The No. 003 aircraft carrier is a nuclear-powered aircraft carrier. The power generation capacity of the nuclear reactor on it is extremely amazing, which can fully meet the power generation needs of a city. The systems involved are also very complex. After all, whether it is the aircraft carrier itself or the aircraft carrier fleet,

, are extremely large.

Liu Yichen spent a week optimizing the system accordingly. This part of the optimization results is naturally not enough, but requires experts to conduct detailed demonstrations and experiments before finally establishing it.

In such a week, Liu Yichen learned more about warships. For military purposes, advancement itself is not the most important. For example, chips may not necessarily use the most advanced chips, but they must be the safest.

All kinds of computers are specially made and made domestically by the military to prevent backdoors from being left in the computers.

Including the phased radar system, it is not the most advanced, but has been used on other ships, but there is no doubt that it is still very advanced in the world. The stealth of the fourth-generation aircraft, under the powerful radar power

, almost nowhere to hide.

Although the No. 003 aircraft carrier has a larger displacement and carries more carrier-based aircraft, the fleet staff is 1,000 fewer than the Qilu ship. The Qilu ship has a smaller displacement than the No. 003 aircraft carrier, but the fleet staff is as many as 3,000 people.

Somewhat different from the Qilu ship, the No. 003 aircraft carrier is made of a large number of composite materials. Its strength is similar to steel, but its weight is significantly reduced.

It can be predicted that this No. 003 nuclear-powered aircraft carrier is actually an experimental aircraft carrier for China.

However, the construction cost of such an aircraft carrier is as high as 50 billion yuan, and if you include carrier-based aircraft and weapons, it will be even more.

Aircraft carriers are such a money-burning thing.

Moreover, if an aircraft carrier wants to exert its true combat effectiveness, it must form an aircraft carrier battle group. The construction cost of an aircraft carrier battle group alone is nearly 100 billion yuan, and the annual maintenance cost is also extremely staggering. If the national strength is not enough, it will not be enough to maintain an aircraft carrier battle group.

Aircraft carrier fleet.

For example, the United States has 11 aircraft carriers with a annual maintenance cost of US$4.2 billion, and the average annual maintenance cost per ship is US$380 million.

Of course, at this time, China must build a strong navy and a powerful aircraft carrier fleet, because without these things, China will be like a child holding gold nuggets in the market. It is too easy for people to become greedy and bullied.

.

Precisely because it has reached a very urgent time, the Chinese Navy has launched dumpling mode. One warship after another has been launched. Whether it is a surface ship or an underwater ship, they are all being updated.

Liu Yichen took a data disk with him, then left the Jiangnan Shipyard on a transport helicopter, went to the military airport, and returned to Narcissus City on a military transport plane.
Chapter completed!
