Two large submarines moved forward slowly, and the propeller at the tail of the submarine rotated at a low speed.

The propeller drives very few bubbles.

With fewer bubbles, the resulting air squeeze will bring less movement and noise.

The two submarines cruised so stealthily at the bottom of the East China Sea. If they didn't have a different mind, ghosts wouldn't believe it.

As for the two submarines running here, God knows what to pay attention to.

"Squeak ~"

The quadruped shouted twice at the two giants. The two submarines ignored him and still sneaked.

Bruce Lee followed the two giants, swam left and right, and devoted himself to research.

Click~

Call~

Just as Bruce Lee was not interested in the two submarines. Suddenly, the water hatch of the Big Submarine opened.

Bruce Lee was stunned and turned to look there.

I saw a long object flying out of the big submarine, far faster than ordinary marine creatures.

"Creak ~"

Bruce Lee let out a soft cry and ran after the object.

In an instant, the object was caught up by Bruce Lee.

"Squeak ~"

Bruce Lee turned around the object several times, but the object still didn't respond. He immediately wondered?

Until I followed the object for a long distance, I didn't see any movement of the object.

Click! Wheezing~

Just when Bruce Lee thought it was a dead object, the tail of the cylindrical object opened, and a small propeller appeared behind it.

Then the object began to sail freely.

Bruce Lee immediately hugged the object and pulled his tail. The object turned a corner and flew again.

"Gaga ~"

Being carried around by this strange object, Bruce Lee is as excited as a six-year-old child when racing.

Freud waves attacked the boat.

Captain Jackson, 42, sat in the submarine command room, frowning and listening to his men report various parameters.

Last week, he received orders from his superiors to participate in a joint military exercise organized by Japan and Bangzi countries.

The area and location of the exercise are in the waters of China.

When he heard the news, he thought his superiors must be crazy.

Entering the Chinese sea for no reason, isn't this an act of death?

But when the order came down, he couldn't refuse to accept it.

Sea wolf nuclear submarine is the most advanced nuclear submarine in the United States.

The Freud attack boat he commanded was upgraded on the original sea wolf attack boat.

Not only is the avionics system in the submarine several times more advanced than other sea wolf submarines, but even the propeller is not comparable to other submarines.

Originally intended to rely on the advanced functions of the sea wolf attack boat, as long as you are careful, this task can be completed.

But I didn't expect that when I first arrived in the waters of China, I met the submarine of Bangzi country.

This damn stick has to follow him.

Several times he sent messages to the damn stick, asked them to leave, and warned them that Freud was going to the Chinese sea. Following him is tantamount to suicide.

Unexpectedly, Bonzi heard that the sea wolf was going to carry out a mission in the Chinese sea area. Like playing a stimulant, he stuck with them and had to see if the Chinese food was flat.

If it's not near the Huaxia sea area, if it's not, the damn task hasn't been completed.

Freud submarine, can get rid of the stick submarine and leave alone.

But Bonzi is Bonzi. It flattered the headquarters and allowed the submarines of Bonzi country to follow.

Although this submarine is not as advanced as Freud, it is also bought by Bangzi in the United States. It can't compare with Freud in various performance, and there is no problem to keep up with Freud.

In addition, the headquarters also gave Jack Su A Secret instruction. If the Chinese military found them, he could leave directly, dive into the deep sea and push the Bonzi submarine out as a double.

Anyway, the submarine can't compare with Freud.

Jackson was still a little excited about the mission.

Put sonar detection systems into the waters of China.

If successful, the entire deep sea of the East China Sea will also be within the detection range of the United States.

Just now, Jackson has launched a torpedo sonar detector.

Why use sonar?

The penetration ability of light in the deep sea is limited. Even in transparent sea water, people can capture objects tens of meters under the water at most.

Radar detection decays too fast in water. The shorter the wavelength, the greater the loss. That is, use high-power low-frequency electric pulses, up to tens of meters.

Sonar is the best way to detect moving objects in the sea.

Over the East China Sea, the United States has reconnaissance aircraft, reconnaissance satellites and various remote sensing detection technologies to fully understand the situation of the whole of China.

But I really don't know anything about the underwater situation.

Especially in the face of giants like China, the United States doesn't even know what China's most advanced nuclear submarine looks like!

As long as this sonar detection captures the dynamic data of some Chinese submarines, the task will be completed.

"Hello ~ has our sonar detection entered the predetermined position?"

Jackson picked up the microphone and said in a soft, inaudible voice, for fear that if he spoke loudly, he would disturb the Chinese submarine.

"Report, sir, I..."

The sonar technician had huge headphones on his head and his hands kept beating on the keyboard. When I saw the sonar detector swimming around on the screen, I looked unbelievable.

"What's the matter?"

Asked Jackson.

"I... our sonar thruster may be broken!"

The sonar technician stammered.

In order to protect submarines, sonar detectors put in will carry thrusters to push sonar to places where Chinese submarines often haunt.

Now, several sonar technicians look at the changing position of Sonar on the screen, looking around like a ghost.

"The thruster is broken? It's impossible! "

Jackson said.

Before the submarine left Japan's Hamaguchi port, these sonar thrusters were checked countless times and put into the magazine after confirming that there was no problem.

"Sir, it's true! Let me pass the data to you! "

The sonar technician said.

A moment later, the screen in front of Jack sun showed the position data of the sonar just launched.

And the whole data keeps beating.

After listening to computer calculation and displaying three-dimensional data on a two-dimensional screen.

The sonar went up and down, left and right in the sea, running in front of the submarine and flying behind the submarine.

"What the hell is going on?"

Jackson scolded.

If the propeller is broken, the sonar doesn't run around like this!

The propeller is broken. The sonar should not move. You know, the propeller turns behind the propeller. Adjust the direction by the tail wing.

If the tail wing is broken, it won't run around like this!

"Sir... We are looking for the reason!"

The shock on the sonar technician's face is still not over.

If the propeller is broken, it should be stationary or slow. After all, it is a propeller.

The tail wing is broken. It should be a deviation from the predetermined orbit. How can there be such a reason for running around?

"Why! Put in a new sonar! There must be a sonar in this position! "

Jackson said.

In this operation, 15 sonar detectors will be dropped at 15 predetermined positions.

Freud's submarine is much larger than ordinary sea wolf nuclear submarine, so it carries two more sonars.

It is important for them to finish the task. Two more sonars are just used as substitutes.
