.When Zhou Yusheng heard the second explosion, he breathed a sigh of relief, but he did not smile slightly as he did at the beginning. Instead, he stared at the data on the navigation control display screen, with a hint of uneasiness and anxiety in his expression, as if the danger had not passed.

In the command cabin, everyone else was very excited and overexcited.

Can you not be excited if you kill the North Carolina without using a single shot?

However, the noise control has not been cancelled, and officers and soldiers can only express their joy with facial expressions and body language, and celebrate the victory just won silently.

Li Xiaoming took out a pack of unopened cigarettes like a magical trick and sent one to everyone.

Mu Haoyang did not refuse Li Xiaoming's kindness, but he did not click it, but just held it in his hand.

From the North Carolina to launch the attack sonar, launch torpedoes at the Shark, and two torpedoes hit the North Carolina one after another, less than ten minutes before and after.

During this time when we could only smoke a cigarette, the fate of two submarines, 276 officers and soldiers, and two intelligence personnel underwent a 180-degree reverse. The North Carolina suffered a fruit and was hit by a torpedo launched by itself, and buried with 134 US military officers and soldiers at the bottom of the sea.

Mu Haoyang did not sigh that on the battlefield of special forces, the transformation of life and death came faster.

He just didn't come back to his senses for a moment, just like he woke up from a dream.

"Old Zhou..."

Zhou Yusheng looked at the cigarette handed to him, waved his hand to Li Xiaoming with a smile on his face, and said to Yang Yuanfan, who was wiping the man while smoking a big mouthful of cigarettes: "Turn to the north, keep a diving depth of 450 meters, and reduce the speed to twelve knots, but do not close the second circuit."

"Don't close the second circuit?" Yang Yuanfan was stunned and looked back at Zhou Yusheng.

Zhou Yusheng nodded without explaining.

"Old Zhou, do this..."

"Do what I said." Zhou Yusheng patted Yang Yuanfan's shoulder, moved to the sonar console, and said to Meng Guangyang who was still busy, "Have you recorded it all?"

"All of them have been recorded, and the sound of the steel plate breaking is very clear." Meng Guangyang handed the headphones to Zhou Yusheng and called out the recorded audio signal from the computer. "Listen, the interval between the two explosions is less than three seconds. Judging from the attenuation of the explosion sound, the hit points are in the first part of the 'North Carolina'. The hit points of the second torpedo are slightly behind, which must have hit the pressure-resistant shell."

"Where are you now?" Zhou Yusheng heard it and returned the headphones to Meng Guangyang.

"It's still sinking, and is about to exceed the limit diving depth of the 'North Carolina'." Meng Guangyang paused for a moment and said loudly, "Did you hear it?"

Without headphones, Zhou Yusheng could hear the creepy sound.

In the command cabin, all the officers and soldiers who were so excited that they could not speak were raised, and listened to the low voices coming from outside the boat with all concentration.

Mu Haoyang also raised his head and looked at the top of the cabin.

Although the sound came from all directions, it seemed to be on the top of the head.

The sound is very low, mixed with a burst sound, just like the sound made when pinching a can, but it is even more dull and the burst sound is louder.

It must be that the pressure-resistant shell of the North Carolina was crushed by sea water!

From a morphological perspective, a submarine is a can that is magnified by millions of times. The pressure-resistant shell bears huge pressure generated by sea water and protects the officers and soldiers inside. After exceeding the extreme diving depth, the pressure-resistant shell will deform and break under a huge pressure equivalent to dozens of atmospheric pressures.

What I hear now is the sound made when the pressure-resistant shell of the North Carolina deforms and breaks.

“What is the depth of the water at the sinking site of the 'North Carolina'?”

"It won't exceed two thousand meters, about 1,800 to 1,900 meters." Meng Guangyang smiled and said, "It's enough to crush the submarine to pieces."

Zhou Yusheng nodded thoughtfully and said, "It's not enough to destroy the corpse."

Meng Guangyang was stunned for a moment, as if he didn't understand the captain's meaning.

"Continue to monitor and pay attention to the abnormal noise on the water, especially in the air." Zhou Yusheng patted Meng Guangyang's shoulder and stuffed the cigarette placed on the control panel into Meng Guangyang's hand.

"Old Zhou, can you breathe a sigh of relief now?" Li Xiaoming came over again and handed the cigarette to Zhou Yusheng.

This time, Zhou Yusheng did not refuse and took the cigarette and lit it.

"You've thought of it long ago?"

Zhou Yusheng glanced at Li Xiaoming, smiled, smoked a cigarette, but did not answer his question.

"I know, you must have thought of it a long time ago. But," Li Xiaoming looked at Zhou Yusheng for a while before saying, "Since you don't plan to let go of the 'North Carolina', why don't you fire a torpedo after the firefight, but take such a big risk and go around with the 'North Carolina'?"

"This is not going around in circles, but fighting for a happy life for you and others in the next few decades."

Li Xiaoming looked at Zhou Yusheng in confusion. What is the relationship between the active sinking of the North Carolina and the happy life in the next few decades?

Before Li Xiaoming could ask, Meng Guangyang shouted: "Captain, abnormal contact!"

Zhou Yusheng's brow jumped a few times and stepped a few steps to Meng Guangyang.

The sonar had already thrown away the cigarette that had just taken two puffs, pressed the headphones hard, and waited until the characteristic value of the noise source appeared on the display screen, and he said: "The targets in the air, three, are approaching at high speed."

"Anti-submarine patrol aircraft?"

Meng Guangyang nodded, and at this time three more wave crests appeared on the display screen. "The sound of entering water, the sonar buoy."

"Old Yang, issue a battle alarm." Zhou Yusheng turned around and said to Yang Yuanfan, "How long will it take to maintain the current speed of the second circuit to be fully loaded?"

"Fifteen seconds." Yang Yuanfan only understood why Zhou Yusheng didn't let him close the second circuit.

Although turning on the second circuit will quickly heat up the cooling water inside without driving the steam turbine, causing a sharp increase in the pressure in the circuit, threatening the safety of the reactor, keeping the second circuit at a high water temperature shortens the preheating time so that the power system can quickly achieve the maximum output power.

"The captain, the sound of slapping is an active sonar buoy!"

"We were discovered?"

Meng Guangyang did not answer because the sound came from answering Zhou Yusheng's question.

The main method used by anti-submarine patrol aircraft to search for submarines hidden deep in the sea is sonar buoys. Especially after submarines widely use overall demagnetization technology and even use non-magnetic titanium alloy to make hulls, the main/passive sonar buoys have become the only reliable detection method for anti-submarine patrol aircraft.

Due to size limitations, the aperture of the active sonar buoy will not be too large, so the working frequency is generally above fifty Hz.

Because the human hearing range is twenty Hz to twenty kilohertz, the sounds made by active sonar buoys can be heard.

"The sound of entering the water is less than three nautical miles at eight o'clock!"

"torpedo?"

"No high-frequency disturbance sound, or sonar buoy."

"What's going on?" Li Xiaoming was a little nervous.

"Anti-submarine patrol aircraft have discovered that we are determining our exact position. The next time we will drop is the aviation anti-submarine torpedo." Zhou Yusheng explained briefly and turned back to Yang Yuanfan, "Start the second circuit, the maximum forward gear, run as fast as you can."

"course?"

"Attached the Troy Peak."

Yang Yuanfan was stunned for a moment, but did not ask any more questions.

Li Xiaoming was startled and asked quickly: "Why don't you avoid it in the south?"

"We used up all the torpedo jamming bombs. Without any shelter, we could not avoid anti-submarine torpedoes in the depths of the empty sea."

"Can't you run away?"

"Racing with anti-submarine patrol aircraft?"

"The range of aviation anti-submarine torpedoes is definitely not as good as that of heavy anti-submarine torpedoes, if..."

"There are three anti-submarine patrol aircraft, each carrying at least two or even four anti-submarine torpedoes. Even if they can avoid the first round of attacks, they cannot avoid the second round of attacks."

"But……"

"You should be happy."

Li Xiaoming was stunned for a moment and did not understand what Zhou Yusheng meant.

Zhou Yusheng smiled and said, "Maybe, you don't have to treat me to a meal."

This is still worthy of happiness!? Li Xiaoming widened his eyes. He didn't feel that his life was not even worth a meal.

"Captain, torpedo enters the water."

Zhou Yusheng nodded and nodded to Lu Chengfeng who had just taken out his stopwatch.

"The torpedo entered the spiral channel and was searching for the target... The sound of continuous slapping, the torpedo has discovered the target... The sound of high-frequency disturbance, the torpedo began to accelerate... The position is 165, the speed is 55, and the distance is 35 chains."

Lu Chengfeng looked at the speedometer above the navigation console and said, "The impact time is five hundred seconds."

“How far is it from the Troy peak?”

"Five Navy." Yang Yuanfan paused for a moment and said again, "It will take another twenty seconds to accelerate to the thirty-five quarters, and we cannot reach in front of the torpedo."

"But it can shorten the range of torpedoes!" Zhou Yusheng said without hesitation, "The front cabin is empty, the head is fifteen, the tail is fifteen, and the depth is fifteen."

Under Yang Yuanfan's control, the "Shark" began to float up urgently.

Because only the front ballast water tank was emptied and the rear ballast water tank was not emptied, the route of the Shark had an angle with the horizontal plane, and it was gradually increasing.

Without intervention, the Shark will eventually float vertically to the surface with its head facing upwards.

But, such a thing will never happen.

"We can avoid this torpedo, but we cannot guarantee that we can avoid the next torpedo." Zhou Yusheng sighed and said to Li Xiaoming, "The Americans must know that the 'North Carolina' is over. They will definitely not let us go. They will soon drop a second anti-submarine torpedo."

"Can you escape this way?"

Zhou Yusheng nodded and said, "The mk46 light anti-submarine torpedo dropped by the anti-submarine patrol aircraft sails at its maximum speed and has a range of no more than five nautical miles. Because it is a tail-chasing attack, we are on the edge of the maximum range of the torpedo. As long as the torpedo is consumed during maneuvering, we can avoid this torpedo."

“So urgently float up?”

"Either dive in an emergency." Zhou Yusheng smiled and said, "The Americans will not make continuous mistakes. Next time they will definitely drop torpedoes above our heads or in front of us."

"So, are we dead?"

"It's not that there's no hope, it's just that it's very slim."

After Zhou Yusheng said this, Li Xiaoming didn't ask any more questions.
