My Super Black Technology Empire

From the time this "Ohio-class" strategic nuclear submarine began to explore along the submarine cable, their ending was already doomed.

The "Nantianmen" plan is absolutely confidential, and anyone who wants to find out the truth will be devastated by Origin.

Of course, this is only relative to other countries' ships, because they are completely out of their control.

If it is Huaxia's ships and ships, Yuanyuan doesn't mind using other more gentle ones, and without losing ships and personnel, it will mislead the other party and minimize the possibility of its own exposure.

However, there is still some risk involved.

On the return journey, Ye Fan took the underwater submarine opened by Yuanyuan and rushed to the South China Sea at a speed of 300 knots, and Ye Fan was also ready to return.

Along the way, through the messages displayed on the screen, Ye Fan could also clearly see that there were intelligent robots coming and going along the way, and submarines were constantly carrying supplies and liquid metal plates.

Such a large-scale submarine project can be concealed for such a long time before it was discovered by the "Nautilus" strategic nuclear submarine. The concealment is already very strong.

After all, the ships and submarines that come and go will not be idle all day to scan the seabed. They are just to explore the underwater hydrological data and topographic information in the vicinity.

It is precisely because of this appearance that the submarine traveling at a speed of 300 knots on the seabed and the submarine cable for communication were detected.

Why use submarine cables?

Because without this, Origin would be completely unable to control such a huge underwater robot, as well as the Iron Legion of a dozen submarines.

The submarine cable is still the main road, and the small section of antenna that the giant signal tower looks out from is only correcting for packet loss and delay through satellite signals.

If there is no such cable, then it is not just a small antenna that is exposed to the surface of the water, but the entire signal tower the size of a buoy that detects waves is completely exposed to the sea.

It's hard not to be discovered.

"Is it stealth and concealment on the seabed? This is indeed a problem. Today's nuclear submarine can be hidden in an accident. If the next time the military's South China Sea Fleet,

When doing exercises,

Accidentally found it along the cable, it would be difficult to do. "Ye Fan was also touching his chin in thought at this time.

Soon, he opened the system and began to search for the technology that could be exchanged in the system.

He wanted to find a way to avoid being identified by sonar on the seabed. After all, the visibility of the seabed is very low. Even a submarine with portholes has a visibility of only tens of meters at most.

Whether you can see the road clearly on the bottom of the sea, the most important thing is to rely on sonar.

After half an hour of searching, Ye Fan finally found a technology that was relatively in line with the current application, and the current technology level was completely created.

The principle of sonar is similar to the ultrasonic detection of bats. It uses sound waves to scan the front, determines the distance and orientation of the target with the frequency of the echo, and can also scan the terrain.

With the current technology of Ye Fan, it is completely possible to build a sonar-absorbing armor, which is the so-called sound-absorbing metal, which can almost completely isolate the sound.

Unlike Captain America's shield, this kind of sound-absorbing metal can only be used for sound insulation. It only needs to add some special ores to liquid metal to make it.

But if sound-absorbing metal is used to absorb all the sonar, it will be easier to identify.

Because it is very simple, the sonar that is generally launched will bounce back within a specific time, and then be accepted by the passive sonar device.

If the whole sound-absorbing metal is used directly, every time the sonar emitted is absorbed, it will become the phenomenon that the surrounding things will bounce the sonar, and only this cable and a specific device will not bounce the sonar.

It is like a piece of white paper, the sonar sweeps like splashing ink, and the location and terrain are determined by the different concentrations of ink, while the position of the cable is particularly black, and the other places are light black, so it is exposed.

If the solution of sound-absorbing metal is adopted, the whole piece of paper will be dyed white, but only the place with sound-absorbing metal is white and not stained black at all, so that it can be seen that there must be something underwater. , will also be exposed.

So Ye Fan found another alternative and a new option.

【Sonic Diffuse Coating】

This coating is like liquid metal, it can be set when it is energized, and its properties are like sound-absorbing metal, which also absorbs sound waves.

However, this kind of sound wave diffuse reflection coating, while absorbing the sound, also transmits the sound to the other end of the coating and emits it again.

In this way, the possibility of being detected by sonar is reduced to a minimum.

It's just that this thing still looks a bit magical, and the exchange price is relatively expensive, reaching 10,000 reputation points.

"This thing seems to be quite good, the system, exchange for the sound wave diffuse reflection coating." Ye Fan said to the system.

"Ding dong, the exchange is successful, the sonic diffuse reflection coating has been exchanged, consuming 10,000 reputation points, and the remaining 61,018 reputation points."

When the sound of the system fell, Ye Fan felt a familiar feeling in his mind. Every time he asked the system to exchange things, the system would inject technology into his mind and memory.

This also caused Ye Fan to feel a little dizzy, but after a minute or two, when his brain got used to it, he could completely get used to it.

After the exchange was completed, Ye Fan directly skipped the introduction page of the sonic diffuse reflection coating and directly clicked on the more detailed effects.

If the obstacle is compared to a wooden board, then under normal circumstances, when the sound wave is transmitted to the wooden board, the wooden board will directly reflect the sound wave back after absorbing a certain amount of sound.

If the front and back sides of this board are coated with a sound wave diffuse reflection coating, then the sound wave will be directly weakened when the sound wave is transmitted to the front side of the board.

That is, through the so-called "diffuse reflection" method, the sound waves are dissipated so that they cannot bounce back.

At the same time, the back of the board will receive the same signal, and the sound of the same size and frequency will be emitted, still in the original direction, the original trajectory, and everything about the sound will be completely unchanged.

When the sound wave on the back of the board is emitted, when it hits an obstacle, it will be reflected back, and it will be reflected on the back of the board again.
