It is not an exaggeration to change a drawing for a nuclear submarine, and the Seawolf-class attack nuclear submarines of later generations are the most advanced underwater hunters in the US military, each costing nearly $3 billion.

The propeller is the propulsion device of a submarine, and its silence level is the most important part of a submarine's stealth ability. It is conceivable how much effort and time the Americans spent on the development of this propeller, and how expensive it was in the end.

At present, China has an industrial base, but in the high-end field, there is a large blank, and military factories can only produce backward weapons and equipment, and no one wants them in the arms market unless they are given away for nothing.

A warship built on such an industrial basis cannot be good!

Therefore, if you don't mention the naval power, they are all decades old ships, and even the coast guard kiosks of little Japan can't beat them.

It is precisely because of the weakness of its navy that China has to temporarily use the mentality of asymmetric warfare to protect its long coastline.

In an asymmetrical war, there is no doubt that using submarines with extremely concealment is the best choice, and using submarines against the powerful aircraft carrier fleet of the US imperialists is a matter of great profit. The military power of US imperialism is an out-and-out king in the air and on the sea, but the world below the surface of the water is fair to any country, and a torpedo fired by a latent conventional submarine can destroy an aircraft carrier worth nearly 10 billion.

Although this submarine has no hope of escaping after launching this suicidal attack and being surrounded by the three-dimensional siege of the US aircraft carrier fleet, its sacrifice is worth it for the country behind it.

The submarine technology that China imported from the Soviet Union in the fifties was an upgraded version of the Type 21 submarine of the German army during World War II, which was already behind the times. As for the self-developed nuclear submarine, it is still a mystery, and whether it can be used or not is known only to oneself.

It's not that the Navy hasn't thought about introducing advanced submarines from the West, but the prices are too expensive, hundreds of millions of dollars at every turn, and it is not enough to even buy a second-hand one to come back for research.

Ordinary conventional submarines in the West, the Navy can be a baby. It is conceivable that the propeller taken out by Chen Xu is simply a priceless treasure for the domestic naval research institute.

Without modification, the propeller was built directly according to the drawings and installed on the old submarine, and the old trees sprouted, and the stealth performance of the submarine was immediately improved.

The reason why Chen Xu made this propeller public, instead of handing it over to the Naval Research Institute, was because he knew that in the future, these people would come up with more advanced submarine power technology.

He is afraid that these people will take this thing as a treasure, and if they don't do it, they will lose their most valuable innovation ability, and then the gains will outweigh the losses.

So Chen Xu would rather use this propeller as an electric fan than give it to the Naval Research Institute.

Chen Xu pretended not to care and waved his hand and said: "Big brother, you misunderstood, this thing is indeed a propeller, but it is not a military secret, but the propeller of the German U2 submarine during World War II. ”

When the matter came to an end, Chen Xu's mind suddenly brightened, and he suddenly thought of a reason to lie, and he prevaricated the matter in an instant.

Although Chen Weiguo was born in engineering, he also knew little about high-tech things like submarines, and said in disbelief: "The propeller of the submarine, you kid really didn't cheat me?" ”

"Big brother, why don't you think about how tightly protected the shipyards of the Soviets produce nuclear submarines! There are layers of heavy protection around, and if you ask me to steal other people's technology, isn't that looking for death! This is the submarine propeller of an ordinary rotten street, and if you take the drawings to the Naval Research Institute as a military secret now, you may be laughed off. Chen Xu nodded heavily, with a serious face, and he definitely couldn't tell that he was lying.

Chen Xu said this, and Chen Weiguo no longer doubted it, after all, this is a military factory directly under the army, and he really wants Baba to go up and offer treasures to the navy, and finally ended up with a joke, and he won't live in the army in the future.

"You kid dares to use a propeller to make an electric fan, in the end you have drunk foreign ink, and your thoughts are different." Chen Weiguo said helplessly

Finally covered up the matter, taking advantage of the eldest brother's turn of his head to take the teacup, Chen Xu wiped the cold sweat on his forehead and sighed, and when the eldest brother turned around, he immediately regained his expressionless appearance.

"Brother, it's not as good as before, making products is to publicize, and the bigger the reputation, the better it sells. This Tokyo Expo is an opportunity to advertise for free, and it is a pity to miss it. Chen Xu still refuses to give up the opportunity to go to Tokyo, in fact, when he saw this news just now, he had already conceived a plan in his mind, he wanted to use this propeller technology to pit Japan!

Once Chen Xu's electric fan is on the booth of the exhibition, the design of the fan blade will definitely attract the attention of people with intentions, and Japan, as a submarine power, will definitely not turn a blind eye to this, and will definitely send someone to contact Chen Xu, wanting to obtain the grinding process and propeller material formula of this propeller.

There is no cheap thing in the world to pick up for nothing, military secrets can only be obtained at a price, although I don't know what Japan will exchange for at that time, but Chen Xu must be a white wolf with empty gloves to pick up cheap for nothing.

The pit dug by Chen Xu is very deep, because he will really teach the Japanese all the complete propeller technology, and even increase the bargaining chips, take some Soviet submarine intelligence and the most advanced submarine technology in later generations to little Japan, and use it to exchange for advanced industrial equipment.

Japan, as the watchdog of US imperialism in Asia, has always had the responsibility of blocking the Soviet Navy's access to the Pacific Ocean, so it attaches great importance to the development of submarine forces.

The technology that Chen Xu came up with was a poison, influenced by the honeymoon period in China and the United States, and also because both countries had to face the strong military pressure of the Soviet Union. In order to jointly confront a strong enemy, the two countries are strictly an alliance, and their relationship is so good that they can give each other almost anything.

Therefore, after the Japanese get these cutting-edge submarine technologies, they will definitely use them in their own submarines.

When Sino-Japanese relations deteriorated, the submarines built by Japan with the technology provided by Chen Xu would be a huge target in front of the Chinese Navy's detection radar, and it would be impossible to hide from them.

That is to say, this batch of submarines in Japan is equivalent to scrapping, and the more you build, the greater the loss, and the pit dug by Chen Xu is no less than the total annihilation of the submarine force of the Japanese Naval Self-Defense Force.

It will take at least a decade to redesign a new submarine, and Japan's 10-year defense hole will provide an excellent opportunity for the Chinese Navy to expand in the South Pacific, perhaps taking over the sphere of influence left over by the Soviet Navy after its withdrawal from the South Pacific.

It's a pity that such a heavy strategic layout action can only be carried out by Chen Xu alone, and he can't discuss it with anyone, and he also has to prevent the guys from the Naval Research Institute from coming out to make trouble, after all, Chen Xu's submarine technology that will come out to pit the Japanese in the future is a real thing, not only the Japanese can't help but be tempted, how can we bear it ourselves?

Once the Naval Research Institute knew that Chen Xu actually took the initiative to hand over such a confidential submarine design to the Japanese, even Mr. Deng could not protect him from such a loser's move, and Chen Xu believed that he would be hung up by the naval commander and whipped to death with a leather whip.

So what Chen Xu has to do is to cook the raw rice first, and when the Japanese get the technology, the naval commander is angry and helpless, after all, the leaked technology can no longer be used, and he is reluctant to kill Chen Xu, maybe this kid still has something good hidden and hasn't taken it out, at most it is a scolding.

After ten years, the navy will realize Chen Xu's good intentions, and this grievance will naturally be resolved.

"This time is too tight, I really can't do it in forty days!" Chen Weiguo is still very unconfident, he is also looking forward to taking the factory's products to the exhibition, but he is afraid of making jokes, as the boss of a military factory, he has a lot of problems, unlike Chen Xu, he can do it if he wants, and he doesn't have to think about the consequences.

"There are more than 10,000 skilled workers in our factory, what a powerful force this is, I have a ready-made design drawing, and it is not a matter of ten days to build an electric fan!" Chen Xu agitated beside him.

This electric fan is used to lure the Japanese into the bait, without which the Japanese will not take the initiative to send people to approach them, and the following qiē plans are meaningless.

Hearing that Chen Xu actually wanted to mobilize the workers of the whole factory to do something, Chen Weiguo shook his head again and again, "No, this is absolutely not good, it will affect the whole body, the factory is not very profitable, and it depends on the things produced every month to make a living, if the whole factory stops production to make you this electric fan, if this thing can't be sold, what will the factory eat next month?" ”

Looking at the eldest brother's hesitant appearance, Chen Xu really wanted to sue him, as long as the Japanese took the bait, it would really be a fat sheep slaughtered, and the factory really didn't have the problem of lack of money. At this time, Japan was at the height of its economic development, and it was spending money all over the world on a shopping spree, and as long as it could be solved with money, it was really not a problem for Japanese people today.

"Hey...... Since the factory is not willing to go all out, then allocate me some more skilled workers! It is best to have strong cutting and grinding skills. It's just that big brother, don't forget, if this electric fan is successful, don't blame our workshop for eating alone in the factory at that time! Chen Xu was very helpless about the indecisiveness of his eldest brother, and could only put forward some minimum requirements very helplessly.

"No problem, how many skilled workers do you need" Chen Weiguo nodded with a smile, and continued: "Don't say it's eating alone, as long as you can do this successfully, I will let the deputy factory director do it for you." ”

"Since it's decided, then please ask my eldest brother for a favor, and now go to each house to help me call all the workshop workers!" Chen Xu put away the vegetable bowl on the table, wiped the grease stains on the coffee table with a rag, and turned around while walking towards the kitchen.

"It's past two o'clock now, what do you kid want to do!" Chen Weiguo said in a daze.

"There are only forty days left before the fair, where is there still time to sleep, of course we have to start work overnight!" Chen Xu waved his arms and said with a smile
