The 055-class large destroyer does not have much presence in China. It is not only because this project belongs to the Ninth Academy, but also because it is a project that challenges the limits of China's naval equipment manufacturing.

The original Class 055 destroyer was the project of the "Suggestions on the Construction of Ocean Escort Ships" in the late 1960s and was also the second air defense ship design after the domestic Class 053 missile frigate. At that time, in order to win over China to fight against the increasingly powerful Soviet Union, the international environment was easy, and it was easier to introduce relevant technologies from abroad to create this project.

Destroyers of this class are because Britain actively contacted China and are willing to provide related technologies for the Type 42 destroyer, that is, Sheffield-class destroyer. The scope includes sea javelin air defense missile systems, combat data systems, olympustm-3b gas turbines, etc., giving China the opportunity to build advanced missile destroyers.

As a result, due to the high technical indicators, the domestic industrial foundation could not be completed independently, and the eventual performance of garbage in the Battle of the Horse Island, the project was terminated.

The Ninth Academy took over this project from the bureau, and the technical indicators became higher, but the tonnage increased to 10,000 tons. At this time, China did not even have the technology to build a warship of 5,000 tons, and directly challenged the missile destroyer of 10,000 tons. When Liu Yijiu proposed the technical indicators, he also added stealth functions. The vertical launch modules required more than 100, which were more versatile. Not only should one have the original ability to carry anti-ship missiles and air defense missiles, but it also had to increase the ability to carry new anti-submarine missiles and cruise missiles.

In other words, the 055-level destroyer built in China can perform almost all tasks such as ground strike, ship strike, anti-submarine, air defense, etc. And due to the flexibility of the vertical launch unit, according to the nature of the mission, it is chosen to focus on air defense, anti-ship and even ground attack, so as to achieve the role of a truly general warship.

Arsenal ship!

It is the name of Liu Yijiu and the entire Ninth Academy for this project they took over from the military, although it is still called Project 055.

Liu Yijiu has not been here for much time in the Shanghai Stock Exchange, especially in recent years, he has basically never been here.

He did not attend the construction and launch ceremony of the first Class 055 destroyer, nor even publicize it.

Although Liu Yijiu knew about the changes in the Shanghai Stock Exchange, he couldn't help but be amazed when he saw it.

In recent years, the whole of China has undergone earth-shaking changes. Not to mention the mainland cities like Chengdu, the international metropolis Shanghai Stock Exchange has even more amazing changes. There are many high-rise buildings, and cars are flowing on the wide roads.

Relatively speaking, the changes at Hudong Shipyard are not that big.

In addition to building a lot of staff dormitories, the office building has a modern atmosphere. The biggest change is that there are two more docks, and the gantry crane has changed from the original 300 tons to 900 tons.

"Director Liu, are there any changes here?" Mai Dongyue was still the director of the Institute 701. When Liu Yijiu came, he personally went to Pudong Airport to pick him up and introduced the changes in the entire Shanghai market to Liu Yijiu along the way.

At the request of Liu Yijiu, he directly arrived at the dock of Hudong Shipyard.

"It is indeed a lot of changes. There are a lot of buildings and they are all new. I just don't know how the technical strength is." Liu Yijiu knew very well what these units were doing with the research funds of the Ninth Academy.

Mai Dongyue said a little embarrassedly, "Director Liu, our canteen was still retained now. Whenever new people come, they will take the anti-corruption education class first, so that everyone knows that our research funds come from difficult times."

Liu Yijiu did not comment.

You can do everything on the surface.

Anyway, the 701 Institute has a cooperative relationship with them.

"Director Liu, are you here?" The person stationed here at the Ninth Academy was a middle-aged man in his forties, Tang Weidong, who was originally an administrator of the Ninth Academy.

Liu Yijiu naturally didn't know Tang Weidong's name, so he nodded and asked, "Soviet experts and technicians are still adapting here, right?"

"Very adaptable. As you told me, when working, we try to keep Soviet technicians together. The design of the Soviet expert building is also in their style. The dietary supply is also specially hired by Russian or Ukrainian chefs to be responsible for... Except for the surrounding environment and the colleagues they worked at were Chinese, it is no different from them in the Black Sea Shipyard and other Soviet machinery manufacturing units." Tang Weidong introduced to Liu Yijiu with a smile.

The working relationship between the Soviets belongs to the Ninth Hospital, not the 701st Institute or the Hudong Shipyard.

Tang Weidong is here specifically responsible for managing experts and technicians from the Soviet Union, and even technicians from the Ninth Academy are under his jurisdiction.

If these treasures from the Soviet Union were not properly placed, their lives would definitely not be easy.

"Director Liu, do you need to go to the Soviet Expert Building to check out? Learn about their living environment and lifestyle." Mai Dongyue suggested to Liu Yijiu.

Tang Weidong hurriedly said, "Director Liu's time is precious. Our Soviet expert building and lifestyle are implemented in accordance with the regulations of the Ninth Court, and there is nothing to visit..."

Liu Yijiu frowned.

But thinking about it, as long as the Soviet experts belonging to the Ninth Academy are all unified standards. There are standards for technical experts, and technical workers.

There are no technicians who surpass domestically, nor are there any technicians who are lower than domestically.

"Let's take a look at the situation of the destroyer first." Liu Yijiu's words made Tang Weidong breathe a sigh of relief.

Mai Dongyue looked at Tang Weidong with a meaningful look. Tang Weidong stared fiercely and could only sigh helplessly.

The area of ​​Hudong Shipyard has expanded considerably, especially the dock, which has four 10,000-ton docks.

Since warship and civilian ship business are separated, this is also conducive to confidentiality.

On the outfitted wharf, a large warship of more than 100 meters long that had been formed and even the radar had been installed quietly docked on the wharf.

Compared with the Yongxing Island, which has been installed, this warship gives people a much less oppressive feeling.

Of course, this is for Director Liu, who has just left the huge missile battleship. For others who have not seen the huge body of the battleship, this battleship, which is 160 meters long and only 21 meters wide, is also as terrifying as a prehistoric giant beast.

Unlike battleships, the 055-level destroyer installed, the superstructure looks very simple. Except for the main mast that has a small antenna on it, the rest are all circular radar devices. The main mast is close to the top antenna, which is equipped with the most advanced radar of this warship - the active phased array radar, which is not visible outside at all.

The entire warship adopts a width and short linearity, with an aspect ratio of only 7.4. This linear warship has excellent seaworthiness, wind and wave stability and maneuverability, and can maintain high-speed navigation under harsh sea conditions, with extremely small roll and pitch.

At the same time, the entire warship's hull and superstructure are designed with inclined surfaces.

These designs were proposed by Liu Yijiu himself.

After a long period of demonstration and experimentation, it was proved that this design has a considerable effect on the invisibility of the warship. Otherwise, the warship would not have taken more than six years from the start of construction to the water installation to the completion of outfitting. Among them, it took more than four years from the start of construction to the launch of the water, and only less than two years from the installation.

The helicopter lifting platform at the tail of the battleship is like a concave model, which is somewhat similar to the most advanced Arleigh Burke-class missile destroyer in the United States, but the difference is that the structure of the deck superstructure is different.

As a veteran, the appearance design proposed by Liu Yijiu almost achieved the best invisible effect. Of course, the angle and other aspects required the first ship to be tested and the appearance was constantly modified.

There are two 051 ships built in the dock, one 055 tons is about to be completed, and the other one is just starting to lay keels.

"In the original design, the length of the 055 ship was 158.2 meters. Before construction, it was simulated many times by computers and the length was the best at 160.4 meters; the width was 21.68 meters, the aspect ratio was 7.4, the draft was 6.7 meters, the standard displacement was 8,420 tons, and the full load displacement was 10,420. It uses four ignition turbines independently developed by Oriental Turbine Factory, with a maximum power of 105,000 horsepower. The maximum theoretical speed was 38 knots and the cruising speed range was 4,600 nautical miles..." As the chief designer of the 055-class large destroyer, Deng Jianjun was very clear about various theoretical data.

Before the construction process, the design parameters of the warship were modified after being simulated by a supercomputer.

Because of such modifications, the Ninth Court has increased the cost of this warship by nearly 80 million.

He was relieved when he saw that Liu Yijiu hadn't said anything.

"What about other communication systems and combat command systems design?" Liu Yijiu usually understands the situation first, and then goes to verify it yourself.

From the beginning, he reminded everyone not to pursue progress, as long as it has better performance.

He was unwilling to create something like the 052 destroyer. He needed to become an advanced missile destroyer in the world until the 052d model.

If you want to do it, you will not fall behind for thirty years.

It is impossible to truly achieve complete invisibility, but for Liu Yijiu, it is necessary to do its best to ensure invisibility performance with the maximum technical level that can be achieved in China.

On this, almost all the stealth designs of the American Arleigh Burke-class missile destroyer are adopted, and some Americans have not yet seen them, and they have not even proposed the design concept of the Zumwalter-class stealth destroyer.

This design makes this kind of design much more advanced than the Arleigh Burke-class.

Of course, domestic power systems, electronics industry, manufacturing technology and even stealth coatings cannot be compared with the United States. Otherwise, Liu Yijiu would directly ask them to find a way to design the 0.55-level 10,000-ton large-scale drive directly according to Zumwalter's standards.

Of course, for the current world navy, especially the Chinese navy, Zumwalter's design concept is too advanced and few people can take over it. If it weren't for the water surface, the fully enclosed hull of the wave-penetrating countership ship would not be able to accept this design. This design is also called a warship.

And the final facts prove that the Zumwalter-class arsenal ship was eventually replaced by a more comprehensive maritime firepower platform.

If possible, Liu Yijiu will now make Zumwalter, and will also turn this kind of warship into a future arsenal ship that can perform submarines.

"The combat system and communication system are all built-in. The end of the chimney smoke exhaust pipe is equipped with infrared suppression devices to reduce infrared radiation; the cabin section uses sound insulation foam, and an air curtain noise reduction pipeline is used inside; to reduce radiation noise; all important systems are impact-resistant reinforcement, and the important cabin uses the 64 armor provided by the Ninth Hospital..."

All of Arleigh Burke have it, all of it are 055.

The design that Arley Burke does not have, 055 still has it.

The so-called 64-type armor is actually graphene armor. In order to keep it confidential, it must be used, and the Ninth Academy finally got such a name.

Deng Jianjun's introduction made Liu Yijiu nod.

At least, from his introduction, the 055 destroyer in front of him has reached the level of Arleigh Burke. Although the performance may be worse than Arleigh Burke due to electronic technology and other issues, there is no problem with these, and with the improvement of domestic technology level, it can be gradually improved.

And if the Arleigh Burke level is to be upgraded, there is no big room.

This thing can be used in the service of Zumwalter-class arsenal ship and will not fall much behind.

"How far has the progress been? How long will it take to conduct a sea trial?" Liu Yijiu stood on the boat platform next to the dock. It seemed that the thing had been installed, and there was no equipment needed to be installed around him. He felt that the installation should be completed, and maybe he was already starting to debug, right?

If this happens, we can conduct sea trials with their missile battleships and go to see the lively return of Hong Kong.

"This..." Deng Jianjun looked at Mai Dongyue beside him, then looked at Liu Yijiu again, without an answer.

Liu Yijiu always felt that these people were a little strange.

There is nothing difficult to answer about his questions.

Immediately asked Wang Jingui, the director of Hudong Shipyard, "Tell me, I heard that you are also in charge of the chief engineer."

Wang Jingui is not someone Liu Yijiu is familiar with.

After all, when Liu Yijiu came here before, Wang Jingui was not the Hudong Shipyard, and the Ninth Courtyard arranged for people to watch the progress here.
Chapter completed!
