"You and I both know that in the United States, there are only eighteen Ohio nuclear submarines, and the first few produced have been transformed after aging because they have been in service for too long. How can we get such a thing?

What?"

While He Shaobo was talking, he remembered that Luo Feng seemed to have brought the raptors, and he began to feel entangled in his heart. He said, "Mr. Xu, what exactly did Luo Feng say? Can you repeat it?"

Thinking of Luo Feng's previous achievements, He Shaobo was now frantically worrying about gains and losses.

It seems like this guy really has the strength to do it, right?

But it seems unlikely.

If you really get it...

Forget it, it seems impossible.

Soon, both of them looked almost crazy, because such a thing was too important to the Naval War Department.

"Mr. Luo said that he will contact his companions and, if possible, send us a brand new Ohio nuclear submarine." When Xu Kaida said this, he did not forget some details, "By the way, he should be responsible for the submarine."

It’s not too familiar, but the full name is always mentioned: Ohio-class strategic missile nuclear submarine!”

Xu Kaida's memory is still very good.

Almost unchanged, he told He Shaobo what Luo Feng said.

After hearing this, He Shaobo's eyes were full of joy, "Did he say that? That's great, maybe it's really possible!"

"No, you mean brand new?"

"Yes, it's brand new!"

"This... brand new?"

"I told you, it's brand new!"

The two of them stared at each other again.

Completely incredible.

Soon, the two of them were successfully turned into pseudo-psychiatric personnel by Luo Feng...

.......

.......

After Luo Feng returned home, he soon began to search for information on the Internet.

In fact, after learning that Xu Kaida was from the Naval War Department, Luo Feng guessed that it should be something about the sea that he needed to get by himself.

Either it’s aircraft carrier technology or radar technology.

Because in Luo Feng's cognitive scope, radar technology and aircraft carrier technology are definitely the two most important points at sea.

But I didn't expect it to be a submarine.

However, after listening to the other party's introduction, he realized that when it comes to things at sea, submarines are no less important than aircraft carriers.

But what Luo Feng doesn't know is that the other party just wants a sonar system.

But Luo Feng came here, you asked for a cage of pig liver, but I gave you a whole pig drama.

Xu Kaida was immediately confused.

Of course, Luo Feng recalled how the other party looked confused and shocked when he wanted to give him a brand new Ohio nuclear submarine.

In fact, I almost couldn't help but laugh on the spot.

Of course, Luo Feng also knew that if he did this, the authorities would definitely know something, but after listening to Xu Kaida's talk for a long time and knowing the gap between China and the United States in terms of nuclear submarines, he couldn't help but do it.

Why are your submarines from fifty years ago still so advanced?

Labor and management just don’t get used to it, okay?

If you can't do anything, that's fine, but if you have such strength, then you have to do it.

If he had thought too much at the beginning, Luo Feng would have just moved the rare metals honestly and then taken his time.

But seeing an old man like Qin Dingguo working so hard for our country, Luo Feng no longer wants to be so cautious.

Of course, I won’t use too much force, but I will never be submissive again.

"In the submarine world? It seems that this sonar system is very important!"

While checking the information, Luo Feng also gained a better understanding of submarines.

Sonar systems include noise sonar and echo sonar.

The main function of noise sonar is to identify and track the hull, as well as measure distance and direction.

Echo sonar is used to observe the position, movement and other elements of the ship hull.

In addition, there are mine detection sonar, water wave sonar, identification sonar, etc.

After all, although submarines can be driven to the surface, most of them still have to work underwater.

When you are on the water, you can still use telescopes and radars. Once you are in the water, you cannot use optical and radar methods.

Therefore, when sailing under sea water, the eyes of a submarine become relatively monotonous. It can only use sonar technology to keep its position safe and to explore the underwater situation and the surrounding environment.

If the submarine is in the sea and has no sonar, it is equivalent to being blind.

If a nuclear submarine is in seawater and the sonar technology is not good, then it will be myopia.

This is a very important technology for submarines. It can be said that the speed of a train depends entirely on the level of the front belt.

Another important knowledge point is the submarine acoustic wave and voiceprint database.

Because after a submarine is launched into the water, it will have a great impact on the surrounding hydrological environment. Every nuclear submarine, even if it has a different model or engine, will still be able to navigate underwater or even when it is stationary.

, will also make a sound.

Such a sound will be discovered as long as the other party turns on the sonar, and there is a huge sound wave database. They will conduct computer analysis based on the sound wave band of your submarine, and finally know your model and discover your trajectory.

As for the sonar voiceprint database, the largest number is not in China, but in Tsarist Russia in the north and the United States on the other side.

After so many years of leadership, it cannot be surpassed in a short time.

And people are always developing. Under such circumstances, domestic technology lags far behind.

"So, what if I get all the submarine voiceprint data in the world!"

"And handed it over to our Naval War Department!"

"Then doesn't it mean that for other countries in the world, as long as their submarines enter our range, it is as if they have come in completely?"

In short, in this way, they have almost nowhere to hide.

But in fact, it is because of the lack of voiceprint database that submarines from other countries often enter our waters.

Although the officials are very worried about this and deeply hate it, there seems to be nothing they can do.

That's what submarines are like, they're too hidden.

And why is the voiceprint database so huge?

Of course, someone else's sonar is advanced and has discovered your submarine, and then collected the voiceprints emitted by your submarine.

Then add it to your own database and analyze it to see what type of submarine you drove in.

"There was really no way before, but now..."

Luo Feng stood up slightly, looked at the information in front of the computer, and laughed.

He knew that from now on, these ghosts in the sea would no longer have a place to hide.

After thinking about it, Luo Feng did not continue reading the information. Instead, he took out the ring and traveled through the interstellar space for a few minutes to the familiar planet Tianyuan.

Soon, Luo Feng entered his Tiangong No. 1 villa.

“It’s still more comfortable in Tiangong Villa!”

"The chairs feel like they are sitting on a cloud, and there is no discomfort at all!"

Luo Feng sat comfortably on a mushroom sofa.

I took a comfortable sip of ice-cold Coke.

This planet is full of sand outside, but once you enter the villa, it's not to mention how comfortable it is.

Luo Feng enjoyed it for more than ten minutes, and then he asked: "Xiaomei, I have a piece of information for you to read. After you read it, help me find a nuclear submarine with similar technology! And then modify it! The exchange

"Bian, you should have statistics on all the ancient machines that can be traded, right?"

The information Luo Feng gave to the other party was, of course, data related to the Ohio nuclear submarine.

"This nuclear submarine? Isn't it an undersea nightmare six thousand years ago?"

When Xiaomei heard this, she was immediately shocked.

Of course.

Of course what shocked her was not how amazing this thing was.

In terms of Tianyuan Planet.

Such a six-thousand-year-old nuclear submarine is simply too weak.

But in the field of ancient machinery, this nuclear submarine is a national treasure-level cultural relic.

It is much more valuable than any ancient car.
