On the dark seabed, the submarine moves slowly with the current like a blind man, and can only rely on sonar to obtain information from the outside world.
A German-made 209/1200 submarine is performing a training mission, sailing slowly under the water of 50 meters in the Marmara Sea. It is affiliated to the Gorkuk Base of the Turkish Navy, with the hull number S-350, and the name is'Ildire'.
The deep diving training lasted for a month, and it was a difficult time for a conventional submarine with only a thousand tons. The thirty-three crew members in the boat stinks like salted fish. Everyone wants to get ashore as soon as possible and take a good vacation.
In the command cabin, the captain is not there. The sonar soldier stared at the water sound display console, but was chatting with the electromechanical non-commissioned officer next to him. The Marmara Sea is the Inner Sea of Turkey, and they don't worry about any danger here.
The Marmara Sea is a closed inland sea with sufficient water depth. The dead hair on the north side collapsed on its own, and the native chickens have no foreign enemies, so there is no need to worry about who can come to make trouble.
The crew members did not abide by the silent discipline, chatting about where to find a woman after going ashore, and which bar to go to for a drink. They do this everyday, and they are a little careless between training sessions.
It's so boring in the submarine.
Just as the crew was thinking about how time could pass faster, there was a bang in the command cabin, as if someone was knocking on the door.
No... the voice was heard throughout the command cabin. To be precise, the entire submarine heard it. The sound is too strange and too clear.
The electromechanical non-commissioned officer looked up in shock, but the space in the submarine was small, and the command cabin was a bit bigger. He is most afraid of something wrong with the pipeline in the submarine.
The sonar soldier quickly looked at his display console, but the sonar showed no abnormality.
what happened
The captain is resting, and the electromechanical non-commissioned officer temporarily takes the command post. He quickly grabbed the internal microphone of the podium and asked if there were any abnormalities in each post.
All posts reported 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's outside the thick hull
Just as the crew were worried about the abnormal noise, the weird sound rang again with a stronger volume. It was as if someone outside the boat was beating a drum, and the sound of'dongdongdong' was endless.
The whole boat was alarmed. After a while, the captain hurried over from the officer’s lounge wearing only a pair of pants, asking loudly what had happened
But apart from getting panic in the boat, no one knew what happened. The sonar display console still shows that everything is normal, and there is nothing wrong with the submarine.
"Float." The captain ordered decisively.
If you don't know the situation, just float to the surface. The local chicken's submarine also has no great secrets. They are not far from the base port, and there is no need to venture underwater.
The sudden noise was too weird, and all the posts in the boat were in place. The high-pressure gas enters the ballast tank with a scream, pushing out the sea water in the boat. As a result, the submarine floated slowly.
The'Ildire' was fifty meters deep underwater at the moment, and it won't take long to float up. But shortly after floating, the power cabin suddenly reported a terrible news.
"Captain, the pressure pipe in our cabin is broken."
The submarine is full of pipelines with various functions. Many of the pipelines are full of high-pressure liquid, and once they are damaged, they cannot be blocked. To make matters worse, bad news came from the electromechanical cabin. The left side ballast compartment of the submarine failed and the seawater could not be discharged.
Everyone in the boat heard a horrible creak-the sea was rushing into the ballast compartment on the left, causing an uneven force on the submarine's hull.
A whole egg is hard to be crushed. But if the egg breaks, it won't take much effort to crush it.
Simply put, the sea may squash this underwater warship. Even if it is not squashed, the submarine will be out of balance, with disastrous consequences.
"Slow down to zero and fill the ballast tank on the right."
The'Ildire' was out of control and leaning to the left. The captain's first thought was to stop and load to the right to restore the balance of the hull. If it doesn't work, he can just sit on the bottom of the sea and wait for rescue.
The Marmara Sea is less than two hundred meters deep, and the 209/1200 type can withstand it.
In order to survive, the crew tried their best to complete the captain's command at a speed far exceeding training. If they are usually proud of it, but today they are frightened, like a god of death.
After a few minutes of intense operation, the ballast tank was all right, and the tubes in the power tank were also blocked. The abnormal sound of'dong dong dong' just disappeared.
But the submarine floats below the sea level at a depth of about fifty meters as if it were still. And it was 50 kilometers away from returning to the port, and the thirty-something men in the boat wanted to cry 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 compartment. To escape the danger, either rescue the submarine from the sea and pull the entire submarine back to the sea safely, or the crew swims out of the torpedo tubes to play'freely floating'.
On the submarine control tower, the distress buoy was sent out. The submarine fleet command in Gorkuk immediately received the message-a 209 submarine failed on its way back
Now there are six submarines in Tuji, all of which are 209/1200 made in Germany. Each one is extremely precious and should not be missed.
But if the situation is known, how can I save it
Through the radio direction finding, the specific location of the distress buoy can be known. A Bell 212 helicopter at the base set off overnight, and the Coast Guard patrol boat was also dispatched.
See what's going on at the scene
The Navy's frogmen are also ready, ready to go to sea to rescue the hapless'Ildire'.
But then
The native chicken navy is also a bit blinded. They do not currently have a professional submarine rescue ship. 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 arrived, news of the local chicken submarine accident disappeared. The western media know that there hasn't been any big news recently, so please pay attention to it.
The crew of the'Ildire' was uneasy underwater and desperately hoped to be rescued. Before long, the distress buoy sent back a message that'Gorkuk' was organizing rescue, so that they could keep calm and report the situation at any time.
The captain has reported the situation encountered by the submarine, and the continuous violent abnormal noise is especially marked. The crew put on the underwater escape equipment, and then there was a long wait.
The distress buoy is a radio transceiver with steel cable reinforcement, cable connection, and communication function. It can not only conduct encrypted communications 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 own distress had spread, and the Western media knew about it-there was no big news recently, the daily secret submarine was suddenly exposed, and the gossip crowd had moved the small bench.
There are also radio chats between shipping ships on the radio.
"I heard that a submarine sank nearby."
"It's a major danger and it hasn't sunk."
"The rescue ship in the port has already been dispatched. The situation does not seem very good. I am afraid it will sink."
"It's not safe under the water, or it's not easy to sink if we float on the surface."
"Yes, yes, it's at least tens of meters deep, and it sinks immediately after a hole is broken."
Ships come and go on the sea, and the crew members'do not concern themselves, hang up high', and they are having fun talking.
The crew of the'Ildire' under the sea was frantic-can you stop'sinking' one by one? We are listening right next to you. Now taboo to hear the word'shen'.
