Chapter 632 Oscar-class nuclear submarine crash

The U.S. Navy has the most powerful aircraft carrier formation in the world. Although the Dalai Lama Navy is constantly developing, it is impossible to compete with them head-on. This can be seen from the combat missions of both sides: the U.S. Navy formation is thinking hard about how to improve its attack The Navy is thinking hard about how to defeat the U.S. Navy.

In this long confrontation, the two sides are constantly developing. Lao Maozi wants to attack the US aircraft carrier formation, that is, from the sky, to the sea, and then to the water, a trinity of strikes. Only a saturation attack can kill the opponent.

The Tu-22M carries anti-ship missiles in the sky, anti-ship missiles of various ships on the water, and cruise missile submarines underwater.

Cruise missile submarines were once the exclusive domain of Lao Maozi. The nuclear submarines of other countries are either ballistic missile nuclear submarines or attack nuclear submarines. There are no nuclear submarines specifically carrying anti-ship missiles. Lao Maozi has developed many models.

The Type 949 nuclear submarine is the pinnacle of them. It adopts a teardrop-shaped hull with an aspect ratio of approximately 8 and a teardrop-shaped bow. Due to the adoption of a twin-propeller structure, its tail is not an ordinary drop-shaped recovery, but has two conical tails. The two propeller shafts extend diagonally from the two conical sterns, and a cross-shaped tail rudder is used. .

It uses an 8.5-meter-diameter inner shell inside, and the widest part outside is as high as 18 meters. In other words, there is a thickness of three to four meters between the inner and outer shells!

Between the inner and outer casings, a specialized 3M-45 "Granite" anti-ship missile is inserted. Yes, it is the same anti-ship missile as the Kuznetsov aircraft carrier, Kirov-class, and Glorious-class cruisers. Missile, a weapon specially designed to hit aircraft carriers!

A submarine can carry 24 anti-ship missiles, cruise underwater, and launch deadly attacks on enemy aircraft carrier formations at any time!

The underwater displacement of the prototype submarine was as high as 18,000 tons. After building two of them, Lao Maozi felt that there were still flaws, so he lengthened the hull by 11 meters. In this way, the underwater displacement also soared to more than 23,000 tons. , larger than many strategic nuclear submarines!

At this time, the K-442 Chelyabinsk was such an improved Type 949A nuclear submarine. This nuclear submarine was started in 1987, launched in 1989, and entered service in December 1990. Just after entering service, the Red Empire disappeared. .

It came to the Pacific Fleet. Since it entered service, it has not sailed very far. After all, the Navy's funding is constantly shrinking. For the nuclear submarine force, it can only maintain the cruise of one or two ballistic missile nuclear submarines. The others have to be in The port is rusty.

With this opportunity, they actively signed up and competed with several Type 971 nuclear submarines, and finally got the opportunity to cruise.

In the 32-meter-long control tower, the captain Avakiants is commanding his submarine with great enthusiasm. It is a rare opportunity for them to go to sea, and they must seize this precious opportunity.

 Sonar soldiers are the most nervous, constantly listening to the movements around them.

“Report, our surface ship formations have converged and are conducting joint exercises!”

 “I heard the supply ship, it was too slow.”

“Continue to monitor, and we may have uninvited guests during our exercises,” Avakianc said.

 “Report, noise detected, behind us!”

A smile appeared on Avakianc's face. As an old submariner, he was already familiar with all this: "Now, tell the whole boat to get ready, we are going to have a Crazy Ivan!"

The Crazy Ivan move is actually what the Americans call it. Big Mao calls it the Soviet Union's Great Slalom, but now they are used to calling it that. They did it once in 1992, and the submariners heard that they were going to do it. All kinds of actions are very exciting.

 “Left full rudder!”

As this order was issued, the huge submarine body began to tilt, and the entire submarine drew a graceful curve underwater. A clear wake low-pressure area was formed at the tail of the submarine.

 Thirty degrees, sixty degrees, ninety degrees, one hundred and eighty degrees!

 Boom, boom!

 The explosion suddenly sounded.

No. 138.

“Report, sonar detected a suspicious explosion underwater.” The sonar operator shouted loudly.

The commander was immediately stunned: "Underwater explosion? What's going on? Contact Damao!"

“Eastern No. 138 called the Varyag. Eastern No. 138 called the Varyag. We heard underwater explosions. Is there any submarine activity underwater?”

　　Everyone on the Varyag was stunned: "Underwater explosion? Why didn't our sonar respond?"

When warships perform different tasks, they turn on different equipment. Now they are searching and rescuing at sea. The very nervous sonar soldiers have not turned on the sonar at all. After all, the noise around them is too loud. Besides, there are submarines protecting them underwater. Nothing to worry about.

 “Sonar operator, what’s going on?”

“Report, we did not detect an underwater explosion.”

“Could it be Dongfang’s misjudgment?”

“Yes, their sonar must be malfunctioning!”

 Everyone was talking about it.

Nicholas also frowned. Of course he knew how seriously his own naval strength had declined over the years. He also knew how rigorous the Eastern Navy was. Since underwater explosions were detected, there must be something going on.

 But, can they admit it? Wouldn't they be compared to each other?

 At this moment, another calling voice came.

“No. 908 calls the Varyag. No. 908 calls the Varyag. We have brought a deep-sea lifeboat. We are now requesting an underwater search and rescue exercise!”

Generally speaking, the communication between the two parties in this kind of joint exercise is carried out through the flagship. Currently, the call No. 908 is illegal. However, now that the situation has changed, Qin Tao must step forward.

That’s right, the voice calling was Qin Tao’s. At this moment, hearing his voice, Nicholas made up his mind: “Change the exercise subject to underwater rescue, immediately!”

During the exercise phase, the formation used the same frequency band for calls, so No. 908 also received No. 138's call to the Varyag. When he heard the call, Qin Tao was immediately surprised.

 An explosion occurred underwater? what's the situation? According to my memory, there can only be one kind!

Whether it was true or not, he couldn't be idle anymore. After all, those submariners were innocent. If an accident happened and all the submariners were killed and he didn't lend a helping hand, he would still feel a little guilty.

 So, Qin Tao immediately pressed the call button and called Nicholas directly.

Qin Tao was still influential. After hearing Nicholas's order, Qin Tao breathed a sigh of relief.

“Please indicate the specific direction of the explosion from No. 138, we are ready to release the lifeboat!”

At this moment, Qin Tao gave orders again. He originally did not have such power, but since the next protagonist was the Jiaolong of the Mingzhou Group, everyone acquiesced in his suggestion.

 After completing the call, Qin Tao walked away.

"Mr. Qin, what are you going to do?" Xu Zhengyang immediately realized something and shouted to Qin Tao.

 “I’m going to the Jiaolong.”

"No, Mr. Qin, you can't go, it's dangerous!" Xu Zhengyang ran forward a few steps and stood in front of Qin Tao. He stretched out his arms to stop Qin Tao.

In the past, Qin Tao went down on the Jiaolong, but after all, there was nothing unusual down there. But it is different now. There was an explosion down there. What if it happens again? Danger, too dangerous!

“Xu Zhengyang, you are so brave, get out of the way!”

"No! If you persist, I will have no choice but to knock you out!"

Seeing Xu Zhengyang's resolute attitude, and considering the gap in their fighting skills, Qin Tao could only shake his head: "Okay, I'll listen to you, I'll go to the monitoring station head office, right? You, you don't even listen to me Now, I have to quickly find a woman to control you from now on!"

 Qin Tao also knew in his heart that Xu Zhengyang was worried about his own safety, which was also Xu Zhengyang's responsibility, so he was not wrong.

I just wanted to go down and see if there was an accident on the Oscar-class nuclear submarine. Now I can only watch it on the monitoring station.

No. 908 stopped in the sea area indicated by No. 138. At this time, the wind and waves were a bit strong. If the mother ship was several thousand tons, it really couldn't start operations. The 30,000 to 40,000-ton No. 908 was as stable as a rock.

Jiaolong has been launched into the water again. Since its birth, it has become an all-rounder. Whether it is deep-sea exploration, underwater treasure hunting, or rescue operations, it can handle it with ease. Now, the underwater situation is complicated, and it is still a leisurely stroll.

On the monitoring station, a picture of the front of the Jiaolong appeared. It was captured by a special camera. Because it used cables towed from the mother ship, it had sufficient power and data transmission channels.

"The average depth of this sea area is more than 1,600 meters. The depth of the sea area where we exercise is 1,200 meters. If there is really an accident on the submarine, then I am afraid it will be more serious than bad!" Zhang Qing was a little worried. said.

Ordinary submarines can only dive to a depth of two to three hundred meters, and nuclear submarines can only dive to a depth of four to five hundred meters. Now, once an accident occurs and the submarine falls to the bottom of more than a thousand meters, the consequences will be disastrous.

"Don't imagine that the submarine is so unbearable." Qin Tao said: "That's just the design depth of the submarine. In fact, the submarine's ultimate dive is far greater than its design depth. Especially Lao Maozi's nuclear submarine, I don't know 949 Is the model made of titanium alloy? If so, it’s a thousand or so meters away, but if it has experienced an explosion, it’s hard to say.”

Submarine technology is top secret. Even if Qin Tao and Nikola have a good relationship, they will not know this top secret information. According to public information, it is a pressure hull with a hybrid structure, partially using yield strength and HY-130 steel. The shell is made of considerable materials, and some are made of titanium alloy.

  However, there are many problems with this statement. Welding titanium alloy is not easy. Can titanium alloy be welded to other steel plates to form a pressure shell? No matter how unreliable it sounds.

 No matter what, the diving depth of the Oscar-class nuclear submarine is still good. Even though it crashed now, I hope it can survive until rescue arrives!

The Jiaolong is still slowly diving, and this process feels a bit long.

 The entire fleet stopped other work and waited for the report from the Jiaolong.

 Varyag.

“Report, active sonar communication not responding.”

 Hearing this answer, everyone's expressions became solemn.

 Electromagnetic waves cannot be used underwater, so it is very difficult for submarines to communicate with the outside world. Generally speaking, satellite communication is used for floating at fixed times. Only in emergencies, active sonar is used for communication.

 But now, even if I send an inquiry using active sonar, there is still no answer from the other side.

This shows what?

K-442 had an accident!

Mao also attaches great importance to the Type 949 nuclear submarine. Even if military expenditures are tight, the construction of the Type 949 nuclear submarine is still maintained. The latest one will be put into service at the end of this year. The Type 949 nuclear submarines in each fleet are now elite.

  I didn’t expect such an accident to happen!

Nikolai's face was gloomy: "The depth of the water here is thousands of meters. If the submarine really crashes, then..."

 “Report, monitoring heard knocking sounds under water.”

This time, their sonar also started working, and they finally heard sounds coming from underwater.

 Percussion sound! what does that mean?

“It means the people inside are still alive, and they are sending a distress signal to us by knocking!” Nicholas said: “Quick, prepare a helicopter immediately!”

 “Where are you going?” asked the adjutant.

“Of course it’s the No. 908!” Nikolai said: “I want to watch their deep-diving lifeboats rescue our crew members. This is really a blessing among misfortunes!”

This exercise is of great significance. It is an exercise for their Pacific Fleet to regain its vitality. Who would have thought that such a change would happen!

The good news is that the subjects of this exercise include sea rescue. Although there is an accident, they can cover it up in the name of the exercise. However, the people inside the submarine must be rescued, and the submarine must find a way to fish it out. Come on, this kind of loss is still acceptable.

Now, Nicholas must rush to No. 908 as soon as possible and personally direct the rescue. He also hopes that this accident will not affect his career.

 Thanks to Qin Tao! This old friend has been helping him for years. Thinking of this, Nicholas finally felt relieved. He believed that with Qin Tao here, this accident could be finally resolved.

The Ka-27 helicopter landed on the deck of No. 908, and Qin Tao was already waiting for Nikolai on the deck.

Nicholas' face was full of seriousness: "Qin, how is the situation now?"

“We don’t know yet. Our deep-diving lifeboat has dived to the bottom of the sea and is currently searching for it. You should also know that it is not easy to find a submarine that has sunk on the bottom of the sea.”

"We have heard the knocking sound. You can follow the sound to find it." Nicholas said.

“Okay, then we will immediately notify the underwater deep-diving lifeboat.”

“Report, Jiaolong has found the target!”

After hearing the news, everyone was nervous, and Nicholas' tone became urgent: "Qin, hurry up, take me to see it immediately!"

 “Okay.” Qin Tao nodded: “Follow me!”

 Nicholas followed Qin Tao to the control console with striding steps. When his eyes saw the graphics on the screen, he felt nervous for a while.

At this time, the Jiaolong had just approached K-442, and the bright searchlight illuminated part of the outline of the submarine. As the Jiaolong moved forward, the shape also changed.

The hull of the boat is relatively upright, with hatches at the top, which brings great benefits to the rescue. The Jiaolong made a half circle around the submarine, and when it came to the front, everyone gasped.

The originally drop-shaped bow of the boat has been blown open with a big hole, which looks terrible. The sailors in the bow torpedo room are probably in danger!

Under water more than a thousand meters deep, the pressure is more than 100 atmospheres, which is higher than the pressure that many high-pressure vessels can withstand. Under this pressure, the submarine's hull can still remain intact, allowing many people to They all lamented that the quality of Damao’s submarine steel is definitely quite good.

Nicholas also breathed a sigh of relief. Only the bow of the boat was damaged, but the back was still intact, which meant that the submariners inside could survive. The sacrifice of a few was acceptable. If they all died inside, it would be a big accident.

The Pacific Fleet will definitely take responsibility, but it cannot be entirely blamed on itself. Over the years, due to the shortage of military funds, submariners have not been out training for a long time. Some accidents have also been caused by unfamiliarity. In the accident After the incident, Nikolai could even get some credit for the timely rescue.

 Thinking of this, he became optimistic again.

“Quick, dock with our submarine immediately and rescue the people inside!”

“As long as it has a standard interface, our lifeboat can be connected to it,” Qin Tao said.

The basic steps for underwater rescue are to move the lifeboat over, dock it to the hatch of the submarine, and then let the submariner inside climb onto his lifeboat. It may not fit in the lifeboat at one time, and it will have to be repeated dozens of times. However, it can be done Docking is always the first step. If docking cannot be achieved, it will be impossible to rescue the people inside.

You must know that under water with a pressure of one hundred atmospheres, as long as a person comes out of a submarine, he will be crushed by the sea water immediately.

 “Standard interface?” Nicholas frowned: “It seems not!”

Lao Maozi never paid attention to lifesaving, otherwise there would not have been the tragedy of the Kursk in the future. At this time, when he thought of this, Nikolai's heart skipped a beat. Suddenly, he thought of something again: "But, There is a floating rescue capsule on the enclosure of the command tower, and the interface of that rescue capsule is standard!”

“Call the Jiaolong immediately and look for the rescue cabin on the control tower.” Qin Tao said.

"yes!"

The Jiaolong began to move again. The picture below was not very realistic and was intermittent. Everyone was sweating in their hearts.

The command tower was getting closer and closer, and the Jiaolong was slowly moving its position, meter by meter. After more than ten minutes, finally, exciting news came from the Jiaolong: "It has been completed. Butt!"

 “Be safe.” Qin Tao shouted.

 Docking is very critical and very dangerous. If the hatch is opened without sealing it in place, seawater under high pressure will pour in, and the Jiaolong will be destroyed.

“Yes, I understand. The negative pressure has been established and is currently stable. It is confirmed to be safe.”

 “Then open the hatch.”

Amidst the creaking sound, the hatch was opened. The rescuers on the Jiaolong looked down excitedly. A big-haired submariner wearing a sea soul shirt climbed up: "Thank you for your rescue. We thought we were all rescued." He’s going to die!”

Below, the captain Avakiyants shouted loudly: "Children, arrange according to age, the younger ones go up first!"

Although he made mistakes when commanding, now, when encountering rescue, Avakiyants still showed the qualities that a captain should have. He did not escape according to his rank, but according to his age!

 They moved very quickly, and within three minutes, the Jiaolong was filled with people.

"People below, please rest assured, we will continue to rescue and will not give up anyone." The rescuers on the Jiaolong comforted them, then closed the hatch and prepared to escape.

On the sea, the wind and waves were a bit strong, and the 37,000-ton No. 908 was shaking slightly. Under the very dangerous situation, the crane lifted out the Jiaolong and placed it on the ship's side.

Nicholas was already standing in front of the Jiaolong, looking at the submariners coming down from above.

"Great, you are finally out of danger. Where is your captain?"

“The captain is still below, and he wants to leave the submarine last.”

 “What happened down there?”

"Report, we found a suspicious target and planned to turn around to find the target, but after turning 180 degrees, we suddenly hit something, and then the torpedo at the bow of the boat exploded."

Among the people who came up, there was a submariner who was closest to the torpedo room and explained the situation clearly and clearly.

 A suspicious target was discovered underwater and then hit it?

Nicholas' face was gloomy: "Order all warships to immediately switch to anti-submarine operations! Call the base to dispatch anti-submarine aircraft!"

The Americans have a professional anti-submarine aircraft like the P-3C, and Lao Maozi is also unambiguous. They modified the Il-38 anti-submarine aircraft based on the Il-18 passenger plane, which is their main anti-submarine aircraft. Now, since there are accidents underwater Target, what else is there to say? Of course we must find the **** perpetrators underwater and make them pay for the losses!

Qin Tao also frowned: "Did the torpedo explode? Did your submarine carry that dangerous hydrogen peroxide torpedo?"

Hydrogen peroxide with extremely high purity is a very dangerous liquid. It is extremely corrosive and oxidizing. It will violently decompose into oxygen and water at 153 degrees. It is used because it is more convenient to store than liquid oxygen, but if it leaks, it can cause terrible dangers.

“Yes, our submarine is equipped with two 65-76 torpedoes, but we don’t know whether this kind of torpedo exploded. When the explosion occurred, we immediately closed the door of the torpedo room.”

The torpedo room exploded and was connected to the outside world. Seawater under high pressure poured in crazily. In order to protect the entire submarine, their only way was to immediately close the door of the torpedo room!

Working on a submarine is very dangerous. Many times, you know clearly that what you do will lead to the death of your companions, but you have no choice. Compared with killing one person in the cabin and killing all the people, this multiple-choice question is not difficult to answer.

 Qin Tao was silent for a minute, and then continued to ask: "Is the nuclear reactor okay?"
