Li Fanyu was also stunned.

Where did this person come from?

In the past, the projects I cooperated with the army were very pleasant. But taking over the gyro project this time made Li Fanyu change this impression. So now when he sees another person in a navy uniform, he doesn't have much affection.

Seeing that Li Fanyu's attitude was wrong, Xing Yaxin looked around, saw the messy documents piled up on the table, and then saw the group of hostile R&D personnel around the door, and roughly understood in his heart.

Although it is not in the same department, the R&D department under the Navy Bureau has always been known for protecting food and eating alone. It seems not surprising that a private company has just stepped into such a department to participate in R&D and has been hostile and neglected.

"What's the matter?

Because he didn't know what the other party's starting point was, Li Fanyu didn't speak.

But Liu Qing beside him didn't care about that, and when he saw that someone had the intention of standing up for himself, he directly sneered: "How can we be wronged? How hospitable the comrades of the 901103 Research Institute are, you see, the necessary information of this research institute is well organized for us, and the comrades are so hospitable, and they are not in a hurry about the research and development project, how can we be wronged?"

Xing Yaxin nodded, let go of Li Fanyu's arm, and walked directly in front of those R&D personnel.

"You 901103 don't take the faith as a dish, we 920524 have to hold it as gold. ”

As he spoke, he waved his hand to a lieutenant beside him, "Go, let the crew line up, let's welcome the Zhengxin R&D team to move!"

"Yes!" the lieutenant snapped a military salute, and trotted out.

"Li Dong, although this is a bit abrupt, but the matter is urgent. It's not that I don't want to communicate with you in advance, but I really can't get in touch with you, let's talk about specific things on the plane, please!"

Seeing the pleading in Xing Yaxin's eyes, although he was confused, he thought that people who came could directly enter the interior of 901103 scientific research base, and there must be no problem with his identity.

Li Fanyu nodded, "Okay." But this time, we came at the invitation of the final assembly. ”

"You don't have to worry about the final assembly, I'll go and communicate with them personally!"

Xing Yaxin saw Li Fanyu nodding, his eyebrows were overjoyed, and he directly waved his big hand, leading the Zhengxin people to walk out.

Outside the base.

A military transport helicopter was checking in on the tarmac, and on either side of the plane, four crew members were standing like javelins.

Seeing Xing Yaxin walking towards this side with a group of young people, the four of them saluted in unison as tense as steel bars;

"Salute! Welcome the Zhengxin R&D team to our 920524 research institute to participate in R&D!"

"Obediently, this is the appearance of asking someone to do something!" Seeing this scene, Liu Qing raised her eyebrows, feeling quite good.

He turned around and glanced at the R&D personnel who came out to see the excitement, and raised his middle finger: "Goodbye to you!

In the whispered discussion of the group of R&D engineers at the 901103 R&D base, Li Fanyu took the lead in boarding the helicopter.

Inside the base, in an open-air office.

"The final assembly knows that it is a good thing to worry about it, and the research and development is good, so send a private company to fill in the mess? As soon as possible, let's get the gyro project out of the test machine, we don't rely on outsiders, we just rely on ourselves to give the base a long face!"

Seeing the helicopter in the distance, Qiao Liang's eyes were full of playfulness, and he commanded his guards.

……

On that navy blue livery transport helicopter.

Xing Yaxin took out a piece of information and put it in front of Li Fanyu.

"Li Dong, this is where I need your help!"

The first one on the profile is a photo.

In the photo, the hull is badly damaged, seemingly chiseled by an invisible sledgehammer, leaning in the dock, like a submarine suffering from Parkinson's disease.

Seeing this photo, Li Fan sighed foolishly and wondered: "Director Xing, we believe that we are engaged in technology, not maintenance." We can't help you with this submarine external damage. ”

"Chairman Li, please look down. Xing Yaxin sighed and pointed to the information.

Li Fan was as good as a stream, and opened the information.

When I saw the whole story of the 325 submarine accident, and saw that the three submarines of the South China Sea Fleet were being played with, and more than 200 submarine officers and men were almost buried at the bottom of the sea, their fists clenched tightly!

"How can this be?!" he slammed the information shut and asked Xing Yaxin.

"The reason for this, in fact, we are still investigating. However, judging from my more than 20 years of experience in the research and development of submarines and underwater combat detection equipment, it is very likely that another country has laid a new type of sonar detection network in the international waters between Mengqi and China's maritime frontier. Different from the previous sonar detection system, this set of sonar seems to be able to detect the submarine sound source of 90 decibels and below, and distinguish the sound source from the noise frequency of the sea water itself, and accurately locate it!

The South China Sea Fleet's Strategy Bureau deduced that it was most likely that our previous island-building operations on the disputed islands and reefs had disrupted the strategic layout of other countries in Southeast Asia, and they made such a response.

But what makes us feel most uncomfortable and uneasy is that since other countries have mastered this new submarine detection technology, the South China Sea is probably not the first, or the only one. What we are afraid of is that the entire submarine shipping lanes in China are already under the surveillance of other countries. Li Dong, this is fatal to our submarine force! This means that every time our submarine goes to sea and makes a dive, it will be exposed under the noses of other countries! If a war breaks out one day, what awaits our submarine will be a catastrophe! The entire Chinese submarine force will be nothing but nothing!"

Li Fanyu nodded deeply, "I roughly understand what you said." So, what do you want us to help us do when you go to such great lengths to come to us?"

Xing Yaxin took out a piece of information again and handed it to him: "Dong Li, the working principle of sonar is to listen to the sound underwater. Within the range of 90 decibels, we have been detected by other countries, so what about 80 decibels? What about 70 decibels? What about 50 decibels? As long as our submarines are quiet enough, then this sonar network of other countries will have no meaning to us! This is all the submarine data of our South China Sea Fleet. Dong Li, we need an all-round silence for our submarines!"

Seeing that Li Fanyu was stunned for a moment, and made a blank expression, Xing Yaxin grabbed Li Fanyu's hand, "I need the noise performance of these submarines, just like your BMW 5 Series!"

Li Fanyu's eyes came to his senses, and he understood in seconds.

"This, easy!"
