in the sky.

The fighter jet automatically circles.

Tang Rui's attention was focused on the maintenance robot.

At this time, the maintenance robot has already removed the propeller from the submarine and will take it back to the base for inspection and repair later.

Next step.

It is to help submarines conduct deeper inspections, such as inner tank metal flaw detection and so on.

How to do it specifically?

Very simple.

First remove the muffler tiles on the outside of the submarine, then cut a hole in the submarine shell to expose the inner tank.

Next, you can perform metal detection on the inner tank.

But before performing these operations, he needed to say hello to the people inside the submarine.

Dangdang...dangdangdangdang...dang...

Under the control of Tang Rui, the maintenance robot used its mechanical arm to beat the submarine shell.

This is not about whether the sub is cooked or not.

It's to communicate with the people inside.

But this noise startled the people inside the submarine.

First came the torpedoes.

Then the propeller disappeared.

Now something knocked on the hull of the submarine again.

Don’t be afraid of whoever you meet.

"Turn on active sonar."

The captain didn't care and just turned on the active sonar.

Normally.

When the submarine is on the seabed, it will only turn on passive sonar, which means it will only receive sonar ripples from the outside world.

In this case, others cannot detect the submarine.

But when a submarine turns on active sonar, it is equivalent to telling everyone that there is a submarine here.

Therefore, most submarines currently are equipped with towed sonar.

But now, the captain doesn't care about this anymore. If he doesn't turn on the active sonar, he really can't stand it anymore.

It's so scary.

Don't even know what's going on outside.

With the active sonar turned on, the people in the submarine also discovered the maintenance robot outside.

"What is this?"

The captain looked at the sonar scrolling and was confused.

He felt that he was confused and confused more times today than in the entire previous half of his life.

Dang Dang Dang...

The maintenance robot outside is still knocking, and it's knocking very rhythmically.

"Captain, this seems to be Morse code."

"Translate it immediately."

The submarines were all professional, and they quickly translated the Morse code.

"Friends inside, are you okay?"

The captain held the notebook and looked at the translation, but said nothing for a while.

"Captain, the knocking outside has stopped."

"Listen, what is it doing now?"

"have no idea."

Duang!

A clearer and more violent sound than before was heard inside the submarine.

"Captain, it's removing our silencer tiles."

"……"captain.

Duang!

There was another loud noise.

If the previous knocking was a threat, then the loud bang now made their hearts tremble.

what to do?

Do you want to float?

"Send a message to the headquarters, report the situation we encountered, and prepare to surface."

The captain took a deep breath and gave the order.

On Tang Rui's side, just as he controlled the maintenance robot to knock down three silencer tiles, a call came from the communication channel.

"Osprey calls to the fish pond."

"I received it from the fish pond, please tell me."

"We are about to arrive, please explain the current situation."

"Okay, the submarine is floating in the sea now, and my maintenance robot has removed its propeller.

It is in a powerless state, and my maintenance robot is currently removing the submarine's anechoic tiles."

After Tang Rui finished speaking.

The Osprey team that came specifically with depth charges and anti-submarine torpedoes fell silent.

The commander on the aircraft carrier island also fell silent.

"Osprey received."

After a while, Osprey said a word.

But at this time, Tang Rui had already seen their figures.

Two J-15 carrier-based aircraft.

Depth charges are mounted on one bottom, and anti-submarine torpedoes are mounted on the other bottom.

They are all big guys.

"The submarine is right below me. If you want to drop bombs, just throw them directly underneath."

Tang Rui said to the Osprey team.

"No need to drop bombs, just use your maintenance robot to force the submarine to surface."

"No more bombs?"

"Yes, it's not necessary."

When Tang Rui heard this, he thought that wouldn't work.

"You're here, just throw one away."

"..." Osprey Team.

"For those who are celebrating the Chinese New Year, listen to the sound."

"..." Osprey Team.

"It's not easy for everyone. If you don't throw a bomb, they will be embarrassed to come up. Let's put ourselves in their shoes and ask you, is it right?"

The commander on the aircraft carrier island also smiled bitterly when he heard Tang Rui's words.

"The fisherman calls the osprey."

"Osprey received."

"Put a depth charge, don't hit it on the submarine, put it next to it."

"Osprey received it, understood."

The Osprey team told Tang Rui about the news of dropping depth charges.

"If you can't blow it up directly, then throw it to the side. My position is directly above the submarine. You can't blow it by throwing it to the side."
