Liu Yijiu stayed at the North Shipyard for a few days, mainly staring at the design team here to quickly come up with a preliminary design plan, and continue to discuss, and then let people modify the huge model. The final model is completely formed, and it has been a week.

The missile launch modules, torpedo launch channels, and torpedo bays that were added later are all made in a simple way so that people can see them at a glance.

The next three months will be the days when the design team will make every effort to modify the design of the bottom submarine cabin.

The missile launching module and the rocket launching module added above can be put on the back and built slowly, which is really impossible. The space and interface are reserved, and they can be installed during sea trials.

The modular design of the weapon embodies super high efficiency here.

After completing these tasks, we are about to enter the 90s, and the entire twentieth century will have ten years left.

Liu Yijiu still had no time to return to the Daba Mountain base, or even time to return to Rongcheng for a short rest. He hurriedly communicated with his superiors, obtained all the technical permits on the 091-class nuclear submarine, and headed for the Jiangnan plant.

The New Year's Eve is approaching, and the well-paid units are all transported to the factory with complete vehicles.

Apples from the north, rice from the south, and specialty products from various places have begun to be shipped on the road.Even Liu Yijiu was filled with dried seafood when he encountered the convoy returning from the Dabashan base to here to send parts.Fresh seafood, such as prawns, etc., will be transported directly by Consolidator for air transportation.

The Ninth Academy's purchasing army for the New Year is unmatched by any unit in the country.

Moreover, these are only charges for the personnel of the military industry system, and the personnel of the civilian unit need to bear the divided transportation expenses.Still let Yun ten busy.After all, the number of Yunshi in the Ninth Academy is not too much, and they fly at high density almost every day.

Liu Yijiu ignored these. For him, the national defense science and technology workers in the Dabashan base are absolutely eligible to enjoy such benefits.At the same time, other units also have this financial strength, and neighboring brother units, if they need it, the Ninth Institute will also provide them, but they must be given money.

From the northern shipyard to the Jiangnan shipyard, it does not take too long to fly.

Jiangnan Factory is also an old military-industrial unit with relatively good treatment in the country, and it is also a unit with good benefits. Although there is a big gap compared with the subordinate units of the Ninth Institute, the courage is relatively top-notch in the entire area.

This shipyard is the top and oldest shipyard in the shipbuilding industry of the Republic, dating back to the Westernization Movement in 1865.

From the Qing government to the Republic of China, and then from the Republic of China to the Japanese occupation, and then to the hands of Lao Jiang, when the new China was founded, it was destroyed by Lao Jiang. However, it was under such circumstances that Jiangnan Shipyard was in The shipbuilding industry of the Republic still occupies half of the country.

In a short time after the founding of New China, one after another "China's No. 1" has been successively created: China's first submarine, the first frigate, the first 10,000-ton hydraulic press, and the first self-developed domestically-made 10,000-ton "Dongfeng"...

Especially in the 718 project "Three Types and Five Ships" that Premier Zhou himself delineated, he undertook all the construction tasks and some of the design tasks, and it also established the first position of the Chinese naval equipment. The development is very rapid, but mainly in the manufacture of civilian ships. Engineering ships, and special ships.For warships, Jiangnan Shipyard has not ordered for many years.

The technical strength is far from comparable to that of the Northern Shipyard and the subordinate shipyards of the 701 Institute before the Ninth Institute had invested heavily.

Although he is very close to the Jiangnan factory, Liu Yijiu has been to the Shanghai Stock Exchange many times, but he has never been to the Jiangnan factory.

Liu Yijiu did not go to the Jiangnan plant’s headquarters, but went directly to their machining unit. There was a deputy director of the Jiangnan plant waiting for him. Although the Jiangnan plant is currently busy, merchant ships, oil and gas ships, etc. are very busy. In warships, what used to be their core technology has now declined.

This can be regarded as a restructured state-owned military-industrial unit.

"Director Liu, it's been a hard journey!" Liu Yijiu just got out of the car, and a gray-haired, potbellied man in a suit in his fifties who was waiting at the entrance of the factory held his hand with a smile on his face.

With his smile, there was only a gap in his eyes.

Liu Yijiu couldn't help but frowned. He shouldn't be a public figure. If the fat man in front of him had seen it, he would definitely have an impression.

As if feeling Liu Yijiu’s doubts, the fat man continued to smile and said, “Director Liu, you don’t know me. I saw you from afar at the 701 technical meeting. At that time, I was just a technical outreach worker. Yeah!"

"My name is Kun Qin, the deputy director of Changfeng Machinery Factory, and I am mainly responsible for the manufacture of your steering wheels and other components."

"Director Qin, I came here mainly to check the production progress of our products. According to the delivery date, there is less than three months left..." After the greeting, Liu Yijiu went directly to the topic.

He really doesn't have much favor with this kind of potbellied officials who gave him a bad impression.

After the reform and opening up, some people who dared to eat crabs became rich first.Of course, some officials in the system who dared to eat crabs get fat first. These people may not have great ability to do business, but their appetite is definitely not small.

Seeing that Liu Yijiu didn't mean to communicate more with him, Qin Kun didn't feel embarrassed at all. He was the deputy director of a subsidiary of Jiangnan Shipyard, and his identity was far from the other party.

Nodded, he led Liu Yijiu and Mai Dongyue to the inside of the factory.

Changfeng Machinery Factory is mainly responsible for the manufacture of large parts, from casting to forging, and then machining. It can also be regarded as the core large-part factory of Jiangnan Factory.

Large parts and components used on commercial ships and engineering ships are Changfeng’s main orders at this time.

In terms of military industry, they are receiving fewer and fewer orders. Perhaps the people at Jiangnan Shipyard are not sure that the factory will not even have much fate with military industry in the future, and they can only provide some parts.

"Listen to Ai Guoxiu, the parameters you provide here, our propellers are designed to have a service life of only two years, and we have to replace them with new ones every two years? In addition, the service life of the main shaft is also not long. One thing?" Liu Yijiu asked directly on the road.

The tone is very flat, but the potential anger is obviously not small.

The problem is very acute. Changing the propellers of a large warship every two years is equivalent to overhauling, especially once the main shaft has a problem, it will be very troublesome to replace it.

Both parties are responsible for the design.

Manufacturing is the unit here, and there is not much direct contact with Jiangnan Factory, although Jiangnan Factory attaches great importance to their projects.

Hearing what Liu Yijiu said, Qin Kun was taken aback, then stopped, and said with an awkward expression, "Director Liu, this is indeed the case. We can’t do anything about this. There is no problem with the design, but in terms of materials and In terms of manufacturing process, we are far from the United States."

"Who doesn't know the gap? The technology used here is the technology of World War II..." Ai Guoxiu was very angry when he heard this."Director Qin, if everyone finds objective reasons, how can we continue our work?"

"The objective reasons are facts!" Qin Kun was even more embarrassed.

"What is the objective reason?" Liu Yijiu's dissatisfaction is also more serious.

He also stopped walking forward.

The environmental planning in the factory area is not very good. Although it is a top domestic shipyard, the management is very chaotic. Various large-scale parts are randomly placed on both sides of the road, just like various sculptures.

"First, material. Iowa-class spindle material is not the original spindle. During the Vietnam War, the spindle and tail propeller were replaced. Although we analyzed the composition of the raw materials, the domestic situation, Liu The director should be clearer; and the second aspect is the manufacturing process, especially the final finishing process..."

These words of him are true.

Even Mai Dongyue couldn't refute it.

Liu Yijiu didn't speak, although the facts are just like this, who can make it clear?

Especially Qin Kun is a fat man.

A few years ago, fat people were rarely seen in China.

It is now everywhere.Only the technicians and workers who really do the job can hardly get fat.

"Let's take a look at our parts first." After reading it, I learned about the actual situation before talking about other things.

Several people moved forward again.

The Changfeng factory has existed for a long time, and before entering the factory area, I heard all kinds of noisy sounds inside.

Liu Yijiu took the earplugs handed over by the director of the Changfeng factory's office and pushed it into his ears before walking towards the machining workshop where there was a huge metal rubbing sound.

Even with the earplugs plugged in, it still can't stop the harsh noise that makes the soul tremble produced by metal tools cutting metal materials.

Although the large-scale factory covers a large area, especially the workshop, it is not small, but there are not many equipment inside.

When Liu Yijiu entered the large parts workshop, he first saw a huge horizontal lathe with a rotating diameter of 1800 mm. On the nearly 20-meter-long guide rail, there was a huge spindle that was slowing down with the lathe chuck. Spin.

The movement of the tool post caused the steel shavings on the slowly rotating huge spindle to drop quickly.

"Rough processing only now?" Liu Yijiu saw this, and his dissatisfaction immediately began to erupt.

If the rough machining is started now, there will be a long natural aging and finishing in the later stage.

How can the service life of the spindle machined in this way be extended?
