On the dark seabed, the submarine moved slowly with the water flow like a blind man, and could only rely on sonar to obtain external information.

A German-made 209/1200 submarine is carrying out a training mission, sailing slowly underwater fifty meters of the Marmara Sea. It belongs to the Gorcook base of the Navy Navy, with a hull number S-350 and its name is ‘Ildirai’.

Deep diving training lasts for a month, and it was a difficult time for conventional submarines with only about a thousand tons. The thirty-three crew members in the boat were as stinking as salted fish. Everyone thought they could get ashore as soon as possible and take a good vacation.

The captain was not there in the command cabin. The sonar soldier stared at the sound of the water and showed the console, but was chatting with the mechanical and electrical officers next to him. The Marmara Sea is a native chicken in the sea, and they were not worried about any danger here.

The Marmara Sea is closed to the inland sea and the water depth is large enough. The dead men in the north collapsed themselves, and there were no foreign enemies in the local chickens, so there was no need to worry about anyone who could come to cause any trouble.

The crew did not abide by the silent discipline and talked about where to find women after getting ashore and which bar to have a drink. They were like this in their daily life, and they were a little careless during training intervals.

It's so boring in the submarine.

Just as the crew was thinking about how time could pass faster, there was a "bang" sound in the command cabin, as if someone was knocking on the door.

No... the entire command cabin heard this sound. To be precise, the entire submarine heard it. The sound came too strange and too clear.

The electromechanical officer looked up in frightened eyes, but the space inside the submarine was small, and the command cabin was a little bigger. He was most afraid of what problems were there in the pipeline inside the submarine.

The sonar soldier hurriedly looked at his display console, but the sonar did not show any abnormality.

What's going on?

The captain was resting, and the electromechanical officer was temporarily taking over the command post. He quickly grabbed the internal microphone of the command post and asked if there were any abnormalities in each post.

The reports of each position are normal, but it is also clear that they have heard abnormal noises, as if they are from outside the boat. The underwater environment is complex, and no one knows what is outside the thick boat hull?

Just as the crew members were worried about the strange sound, the strange sound rang again with a stronger volume. It was like someone was beating a drum outside the boat, and the sound of "dongdongdongdongdongdongdong" continued.

The entire boat was alarmed. After a while, the captain hurried over from the officer's lounge with only a pair of shorts and asked loudly what was going on.

But except for the increasing panic in the boat, no one knew what was going on. The sonar display console still showed that everything was normal, and there was nothing wrong with the submarine.

"Float." The captain decisively ordered.

If you don’t know the situation, just float to the sea first. There is no great secret for the submarines of the native chickens. They are not far from the base port, so there is no need to venture underwater.

The sudden sound was so weird that all the positions in the boat were in place. The high-pressure gas entered the load bay with a scream, pushing out the sea water in the boat. The submarine slowly floated up.

The 'Ildirai' is now fifty meters deep underwater, and it won't take long to float up. But after a while, the power compartment suddenly reported a terrible news.

"Captain, the pressure pipe in our cabin is broken."

The submarine is covered with pipes of various functions, and many of them are full of high-pressure liquid, which cannot be blocked if damaged. What's worse, bad news also came from the electromechanical cabin, and the left side of the submarine's bay was malfunctioning and could not be discharged from sea water.

Everyone in the boat heard a creepy creaking sound - the sea water was surging into the left load compartment, causing uneven stress on the submarine hull.

A complete egg is difficult to crush. But if the egg is broken, it will not take much effort to crush it.

Simply put, seawater may flatten the underwater warship. Even if it is not flattened, the submarine will be unbalanced and the consequences will be unimaginable.

"Reduce to zero, and the right side of the ballast is filled with water."

The "Ildirai" was losing control and leaning left. The captain's first thought was to stop first and load it to the right to restore the balance of the boat. If it really didn't work, he could just sit on the bottom of the sea and wait for rescue.

The deepest sea of ​​Marmara is less than 200 meters, and the 209/1200 model is completely affordable.

In order to survive, the crew tried their best to complete the captain's order at a speed far exceeding the training. If they were usually proud of this, they were frightened today, as if they met the God of Death.

After a few minutes of intense operation, the loading chamber was fine and the pipes in the power chamber were blocked. The abnormal noise of the "dongdongdongdongdong" just now disappeared.

But the submarine floated at sea level about fifty meters deep as if it was still. It was fifty kilometers away from returning to the port, and the men in the 30th boat were crying without tears.

"Send a buoy for help and ask for help from the port." The captain ordered.

The 209/1200 submarine does not have a separate escape cabin. If you want to escape, either rescue the sea and pull the entire submarine back to the sea safely, or the crew swim out of the torpedo tube to play "freely float up".

A buoy was sent out on the submarine command tower. The submarine fleet headquarters located in Gorkuk immediately received a message - a 209 submarine failed during its return journey?

Now there are only six submarines in the country, all of which are made in Germany. Each one is particularly valuable and cannot be missed.

But when the situation is known, how can I save it?

Through radio direction finding, we can know the specific location of the rescue buoy. A Bell 212 helicopter at the base set off overnight, and even the patrol boats of the Coast Guard were sent out.

Let's see what's going on?

The navy's frogmen were also ready to go out to sea to rescue the unlucky "Ildirai".

But then what?

The Navy is also a little confused. They do not have professional submarine rescue ships now. After confirming with the submarine many times, they can only contact civilian ships at the port overnight to serve.

Before the civilian salvage ship arrived, the news of the accident of the native chicken submarine disappeared. Western media all knew about it, and there was no big news recently, so please pay attention.

The crew of the "Ildirai" was nervous under the water and desperately wanted to get rescue. Not long after, the buoy asked for help sent back the message. "Gorcook" was organizing rescue to keep them calm and report the situation at any time.

The captain had reported the situation encountered by the submarine, and the continuous violent noises were particularly marked. The crew put on the underwater escape gear, and then there was a long wait.

The help buoy is a radio transceiver with steel cable reinforcement, cable connection, and communication function. It can not only communicate with the headquarters, but also accept ordinary communication contacts from the outside world.

Not long after, the crew learned that the news of their own distress had spread, and Western media knew it - there was no big news recently, and the daily secret submarine was suddenly exposed, and the gossip crowd had moved the small stool.

There are also radio chats between shipping vessels in the radio.

"I heard that a submarine sank nearby."

"It's a major danger, and it's not sinking yet."

"The rescue ships at the port have been dispatched, and the situation seems not good. I'm afraid it will still sink."

"Is this unsafe under the water or what we float on the water and it is not easy for us to sink."

"Yes, yes, it's at least a few dozen meters deep, and it will sink immediately after breaking a hole."

The ships came and went on the sea, and the crew members were so happy that they were talking about it.

The crew of the "Ildirai" under the sea was so angry that they were crazy - can you stop "shen"? We are listening next to you. Now it is taboo to hear the word "shen".
