Although the key core workshops of military units such as aerospace have not been as strict as before in recent years, they are still not accessible to ordinary people.

It is the people who work in this production workshop that must go through various inspections every morning when they go to work, and mobile phones and other communication equipment are not allowed to enter, and this work is not allowed to come out for eight hours.

The production of high-precision and cutting-edge military products is so strict.

Under the leadership of Sun Qianming, the technical vice president, and She Hongwen, who has a higher administrative level than him, the internal guards of the assembly workshop, who are not visible from the outside at all, only looked at the documents of these two people, and did not let Yun Kai and Liu Hu take out their ID cards or anything, nor did they ask them to hand over their mobile phones and other electronic devices with camera functions.

Anyway, there are these bigwigs, and if something happens, they are looking for them, and it has nothing to do with the security personnel, after all, these leaders may have important things at any time, especially people of She Hongwen's level.

"Isn't it, the security system here is stricter than the headquarters building outside?" Liu Hu saw that there was only one person in and out of the entire fully enclosed huge workshop, and there were several cameras set up on this passage, and he couldn't find any dead ends with his professional eyes!

"China's most advanced missiles are produced in this workshop, how can security not be strict?" Sun Qianming said with a smile.

He is only the vice president in charge of technology, not the vice president in charge of security, but he can hear the praise of Liu Hu, who is said to be from the special forces, which is enough to make him proud.

But there's security here. There is no comparison with the assembly workshop of Daba Mountain.

"There aren't many people in this workshop? You can't build many missiles in a year, right? After entering the huge production workshop, Liu Hu's face showed a disappointed expression.

This is completely different from the high-tech production workshop he imagined.

Missiles are this thing. It's a high-tech thing, it's actually made in an ordinary production workshop environment, such a big gap, how can a person like him who has countless visions not be disappointed.

He thought that in such a workshop, at least the production workers were tightly covered, and they were wearing white coats everywhere. The staff with only their eyes exposed manipulated all sorts of sophisticated equipment to get it out.

"Tiger, for ordinary people, missiles and rockets are indeed high-tech products that cannot be imagined, but for people like us who are engaged in machinery, they are actually no different from other ordinary mechanical parts." Yun Kai explained to Liu Hu.

"Let's start with the very beginning, every part of each missile. Even if it is a screw on it, after entering the material warehouse of this workshop, the material number will be entered, so that you can find out who designed the material produced by the manufacturer that was used at the beginning. Who produces, who inspects, who transports, so that once there is a problem when it is used. We will be able to trace any production and logistics link and find out where the problem is...... "For Yunkai." Sun Qianming is now showing great enthusiasm, and he also knows that Yun Kai knows the entire assembly process, and he still introduces it in great detail.

He introduced it like this, but it was not for Liu Hu, Liu Hu himself knew that he didn't have such a big face.

"Actually, this is no different from the production process of other military products...... Forget it, when I didn't say it, you don't even know the most basic mechanical equipment production, and if you say it...... "Yunkai originally wanted to sue Liu Hu that the production and assembly process of all mechanical parts in the whole world is actually the same.

This is more stringent than the production of ordinary civilian mechanical products, and some civilian products with relatively high requirements are also using military standards.

It is necessary to ensure that each part can be traced, that is, if there is a problem, it is possible to find which part and which process that the person did, and the number of various quality records, which must clearly reflect the state of the part at that time.

"The warehouse here is just a transfer warehouse, for example, what we want recently, the personnel of the warehouse must be according to the production plan issued by the workshop production scheduling and the bill of lading from other finished product warehouses to the warehouse here to do a good job of marking, and then during the assembly, the warehouse management personnel put these products into the hands of the person in charge of the assembly on the workshop site, layer by layer......

"And what are these circles on these shelves out there for?" Zhang Hu's words made Yun Kai suddenly take a step to the side, and then look like I didn't know him.

"These shelves are all parts of some missiles, our assembly workshop is mainly to produce some short- and medium-range missiles, although you look at a lot of medium-range missiles are relatively long, but they are assembled from a lot of parts, these parts that you call a circle, is the link object of a certain type of missile."

Sun Qianming sighed, he was really an idiot who didn't understand anything.

But it's an idiot or not, just look at the excitement, save yourself from going out and talking nonsense, and then find out that you brought him in by yourself, and it's not easy for you to explain.

"Here, each row of shelves is the same as the position of each part of the missile, from the front of our question, we belong to the tail here, and the front is the head, all of which move these assembled parts to the front through the movable material car, and each different person is responsible for different positions, in fact, it is the assembly line assembly ......" Seeing Yun Kai's lack of interest, Sun Qianming did not have much interest.

And She Hongwen and Zeng Yong, who were following on the side, were constantly glancing at him and asking him to end the visit quickly.

"Don't touch those parts, although these parts still have to be treated, but sweat, oil stains, etc., on people's hands, will have a subtle impact on the performance and accuracy of these parts......"

Seeing that Liu Hu was about to touch a thin-walled aluminum alloy connection shell above the value, he hurriedly stopped.

Yun Kai was funny when he heard what he said. These parts don't have such requirements at all, but it's good to scare Liu Hu. Save him from touching it, these parts that enter the assembly workshop can't have problems, otherwise many people will be unlucky.

After all, these parts have relatively high requirements, and if they are deformed or something, they will affect the accuracy of the assembled missile.

"Most of these missiles are connected by threaded fasteners. Some are welded, and some are riveted......" Sun Qianming explained to the two circles in Liu Hu's mouth that a master was welding on the workbench.

Different parts of the missile require different connection methods.

"In order to reduce the weight of the missiles and make their range as large as possible, most of the parts are made of aluminum alloy, some key parts. For example, the head is equipped with various control instruments, guidance computers, combat units, etc., and the shells are all special steels, mainly to protect the various parts inside from damaging the control unit inside during the flight process......"

"Of course, after the whole machine is installed, the outside is sprayed with a layer of thermal insulation coating that is several millimeters or even tens of millimeters thick......

"These shells are in the assembly process, and the large missiles are not equipped with electronics or anything. But the small ones will be loaded except for no fuel, and the fuel will be loaded last......"

Yun Kai really didn't have any interest in these little guys, if they were those giants, they would be able to fly across the Pacific Ocean from Huaxia. A strategic missile that lets a nuclear warhead explode on the territory of the United States is about the same.

But he knows. For Liu Hu, even the air-to-air missiles used by the Air Force with a very short range or the missiles used by the Sixth Army that are only arm thick are terrible things.

The production base on the bus is not something that ordinary people can enter casually.

Even with Sun Qianming's leadership, it can't work.

This workshop can be easily entered, after all, it is not too core to produce, and it is all non-dangerous things without the Ministry of Warfare and propellants, otherwise it would not be put into the production factory in the city to produce.

"After all these parts are installed, then install the tail that controls the flight attitude, and then spray paint, install the motive, even if it is done, adding propellant or something to it, it is not our workshop to do......" Under the urging of She Hongwen and Zeng Yong, Sun Qianming quickly let Liu Hu know how the missile was made.

However, this is only an assembly link, the others are production or something, the process is too long, he is too lazy to take him to visit, and Yunkai did not ask for it.

"How about we go over there?" Although his knowledge has risen sharply, Liu Hu is still very confused.

He saw that several workers not far away were assembling a slender missile about the size of a basin, but five or six meters long, and he was immediately interested.

"Let's go, these missiles are produced like this, nothing unusual!" Seeing Sun Qianming's embarrassed look, Yun Kai spoke.

According to his inference, that thing over there is very likely to be the kind of cruise missile that Wu Feng's Longguang Machinery went bankrupt, and this is the latest test model!

Don't let anyone in!

"Why didn't you see the assembly here?" Liu Hu really wanted to touch these things that once gave him infinite longing and infinite dreams.

However, his casual question, and suddenly Sun Qianming's faces changed greatly.

And Yun Kai on the side also frowned!
