In the dark seabed, the submarine moves slowly with the current like a blind man, and can only rely on sonar to obtain external information.
A German-made Type 209/1200 submarine is performing a training mission, sailing slowly under 50 meters of water in the Sea of Marmara. It is affiliated to the Turkish Navy's Goluk Base, and its hull number is S-350, and its name is 'Iraq.
Erdire'.
The deep-diving training lasted for a month. For a conventional submarine with only a thousand tons, it was a difficult time. The thirty-three crew members inside the boat stunk like salted fish. Everyone wanted to get ashore as soon as possible and have a good life.
Take a vacation.
In the command cabin, the captain was not there. The sonar soldier was staring at the hydroacoustic display console, but chatting with the electromechanical sergeant next to him. The Sea of Marmara is an inland sea, and they were not worried about any danger here.
The Sea of Marmara is a closed inland sea, and the water depth is large enough. The dead ones in the north collapsed on their own, and there are no external enemies. There is no need to worry about anyone coming to cause any trouble.
The crew members did not abide by the silence rule and chatted about where to find women after landing and which bar to go to for a drink. This was what they did every day, and they were a little careless during training breaks.
It was too stuffy in the submarine.
Just as the crew was thinking about how to make the time pass faster, there was a "boom" in the command cabin, as if someone was knocking on the door.
No... the entire command module heard this sound. To be precise, the entire submarine heard it. This sound was too strange and too clear.
The electromechanical sergeant looked up in fright, but the space inside the submarine was small, and the command cabin was only a little bigger. He was most afraid of something going wrong with the pipes in the submarine.
The sonar soldier quickly looked at his display console, but the sonar showed no abnormality.
what happened?
The captain was resting, and the electromechanical petty officer temporarily took over the command position. He quickly grabbed the internal microphone of the command console and asked if there was anything abnormal at each position.
The reports from each post were normal, but they also made it clear that they heard abnormal noises, which seemed to come from outside the boat. The underwater environment is complicated, and no one knows what is outside the thick hull of the boat?
Just when the crew members were worried about the abnormal noise, the strange sound sounded again with a stronger volume. It was like someone was beating a drum outside the boat, and the sound of "dong dong dong" was endless.
The whole ship was shocked. Soon the captain, wearing only a pair of underpants, hurried over from the officer's lounge and asked loudly what happened.
But apart from getting more and more panicked, no one inside the boat knew exactly what was going on. The sonar display console still showed that everything was normal and there was nothing wrong around the submarine.
"Float up," the captain ordered decisively.
If you don't understand the situation, just surface to the surface first. There are no big secrets about Tuji's submarine. They are not far from the base port, so there is no need to take risks underwater.
The sudden sound was so weird that all positions in the boat were in place. High-pressure gas entered the ballast tank with a scream, pushing the seawater out of the boat. The submarine slowly floated up.
The 'Yildire' was currently fifty meters under the water, and it would not take long for it to surface. But not long after it surfaced, the power cabin suddenly reported a terrible news.
"Captain, the pressure pipe in our cabin is broken."
The submarine is full of pipes with various functions. Many of the pipes are filled with high-pressure liquid. Once damaged, they cannot be blocked. To make matters worse, bad news came from the electromechanical room. The ballast tank on the left side of the submarine failed and the seawater could not be discharged.
.
Everyone in the boat heard a creepy creaking sound - seawater was pouring into the ballast tank on the left side, causing uneven stress on the submarine shell.
A whole egg is difficult to crush. But if the egg is broken, it won't take much effort to crush it.
To put it simply, the sea water may flatten the underwater warship. Even if it is not flattened, the submarine will be unbalanced and the consequences will be disastrous.
"Decelerate to zero and fill the ballast tank on the right side with water."
The 'Yildire' was tilting out of control to the left. The captain's first thought was to stop and load the boat to the right to restore its balance. If that didn't work, he could simply sit on the bottom of the sea and wait for rescue.
The deepest depth of the Sea of Marmara is less than 200 meters, and the Model 209/1200 can fully withstand it.
In order to survive, the crew tried their best and completed the captain's orders at a speed far exceeding their training speed. Normally, they would be proud of this, but today they were as frightened as if they were facing death.
After a few minutes of intense operation, the ballast cabin was fine and the pipes in the power cabin were blocked. The abnormal sound of "dong dong dong" just now disappeared.
But the submarine floated as if it were still under the sea level at a depth of about fifty meters. And it was still fifty kilometers away from returning to the port. The thirty or so men in the boat were crying without tears.
"Send a distress buoy and call for help from the port." the captain ordered.
Type 209/1200 submarines do not have a separate escape hatch. To escape, either rescue operations on the sea surface bring the entire submarine back to the surface safely, or the crew members swim out from the torpedo tubes to "free float".
On the submarine control tower, a distress buoy was sent out. The submarine fleet headquarters in Golkuk immediately received the message - a 209 submarine had a malfunction on its way back?
Now there are only six submarines in Turkey, all of which are German-made Type 209/1200. Each one is particularly precious and cannot be lost.
But now that we know the situation, how can we help?
The specific location of the rescue buoy can be known through radio direction finding. A Bell 212 helicopter from the base set off overnight, and a Coast Guard patrol boat was also dispatched.
See what's going on at the scene?
The Navy's frogmen were also ready to go to sea to rescue the unfortunate ship "Yildire".
But what then?
The local navy is also a little confused. They do not have a professional submarine rescue ship now. After confirming with the submarine many times, they can only contact civilian ships in the port overnight to provide services.
Before the civilian salvage ship could arrive, the news of the Tuji submarine accident disappeared. The Western media all knew about it, and there happened to be no big news recently, so let’s pay attention.
The crew of the 'Yildire' was uneasy underwater and desperately wanted to be rescued. Not long after, the rescue buoy sent back a message that the 'Golkuk' was organizing a rescue, asking them to stay calm and report the situation at any time.
The captain had already reported the situation encountered by the submarine, and the continuous violent abnormal noises were specially marked. The crew members put on underwater escape gear, and the next step was a long wait.
The rescue buoy is a radio transceiver with steel cable reinforcement, cable connection, and communication function. It can not only carry out encrypted communication with the headquarters, but also accept ordinary communications from the outside world.
It didn't take long for the crew to learn that the news of their distress had spread, and the Western media knew about it. There has been no big news recently. The submarine that was secretive in daily life was suddenly exposed, and the gossips had already moved their seats.
There is also radio chatter between shipping vessels on the radio.
"I heard that a submarine sank nearby."
"It encountered a major danger, but it hasn't sunk yet."
"The rescue ship at the port has been dispatched. The situation does not seem to be good. I am afraid it will still sink."
"It's not safe if it's under the water, or it's not easy for us to float on the surface."
"Yes, yes, it's at least dozens of meters deep. If you break a hole, it will sink immediately."
Ships were coming and going on the sea, and the crew members were chatting happily.
The crew of the 'Yildire' under the sea are going crazy with anger - can you please stop saying 'sink' one by one? We are listening right next to you. It is taboo to hear the word 'sink' now.
