Kayama Noriichi, who had narrowly escaped death, no longer had the pride he had when he set out, nor the high spirits he had when he ambushed the supply ship. Now he is holding on to the door frame of the sonar room, leaning next to the sonar soldier's head, waiting at any time.
According to the sonar soldier's report, it has been 3 hours since he escaped from the strait, and now he
Our course was northwest, and there was definitely no way back from the original route. Even if he told Kaguyama Kiichi that the destroyers had evacuated, he would not dare to go back again. The feeling of being underwater and waiting for a bomb to fall on his head was too torturous.
If this happened again, Kashan Jiyi couldn't guarantee that he wouldn't go crazy.
Since there is no way to go back, we can only choose another route. The closest one now is to take the Sulu Sea and then enter the South China Sea. Huashan Jiyi also chose this route. Now his mind is very confused.
, he was very surprised, his submarine team had been very careful, and he could guarantee that his submarine team had not exposed its whereabouts along the way, and they were active day and night, so it was unlikely that their whereabouts had been discovered.
If this is not the case, Kaguyama Kiichi suddenly thought of another possibility, that is, the Federation Navy is also equipped with the same submarine detector, and its performance is much better than that of the Imperial Navy, because its own submarines are also equipped with
Submarine detectors found no traces of other submarines, but their own traces were discovered.
"We must return to the mainland and report this situation to the Navy Department. Let those arrogant naval officials wake up and stop thinking that with this kind of detector, they can restrain the submarines of the South China Sea Federation." Originally, this was the attitude.
The ideological Kayama Noriichi seemed to have suddenly matured a lot after this experience of escaping from death. It seems that experiencing life and death will make a person more rational.
"General, there are two destroyers approaching from behind us. The current distance is about 1 nautical mile." Just as Noriichi Kalashama was thinking about how to persuade those stubborn naval generals, the sonar soldier suddenly turned his head.[
"What? Destroyer? Are they coming for us?" Kiichi Kayama was startled and asked quickly.
"The direction is towards us. I don't know if it is passing by or has a target." The sonar soldier could not judge the purpose of the surface ship.
"Baga...quarter speed, left rudder 10 degrees." Huashan Jiyi had gone through life and death. He was much calmer, and he only hesitated for a few seconds before giving a new order.
At this time, everyone in the command module almost knew that the destroyer was approaching, and everyone's eyes showed fear. They operated the equipment in their hands according to the captain's orders and exchanged glances with each other.
"General, they also changed their course. They are still coming directly to us. We may have been exposed!" A few minutes later, the sonar soldier told another fact that made Kiichi Kayama and other submarine officers and soldiers despair.
"Impossible, how do they know our position?" Huashan Ji looked at the periscope subconsciously, but it did not rise. In other words, the submarine is now fully submerged. If it can be discovered by the federal navy,
Then there is no other way. As a special kind of naval ship, the submarine's only advantage is hiding. If even this advantage is lost, it will be a big steel coffin, even a coastal gunboat of several hundred tons.
It could kill it.
"They slowed down. They were right above our heads...but they didn't drop bombs..." The sonar soldier still adhered to his duty and reported everything he heard to his captain intact.
"Stop..." Huashan Jiyi refused to give up.
...ten minutes later...
"They are slowly circling above our heads..." The annoying sonar soldier told the truth again.
"..." Kawasama Kiichi was already sweating profusely at this time. It was obvious that the two destroyers on the surface must have discovered his submarine. As for how it was discovered, it is no longer important. Kawasama Kiichi
I have tried every possible means to get rid of their tracking.
"They didn't throw bombs. They probably wanted to capture us alive. We must not fall into the hands of these Chinese people. For the honor of the Emperor and the honor of the Imperial Navy, I decided to sink myself..." Noriichi Kayama was silent for a long time and finally said
made his final decision as captain.
The air in the submarine was very bad. After a long period of submersion, most of the oxygen had been used up. There was still tangible pressure above the head, making the atmosphere in the cabin so thick that you could feel the texture. All the crew members came to the aisle.
, the chef also took out the few remaining sake, and everyone drank it in small sips. Some young crew members had quietly shed tears.
Kaguyama Noriichi stood next to the periscope, stroking the thick copper tube of the periscope with his hand, and took the lead in singing the songs of his hometown. Since most of Japan's naval officers were from the Satsuma clan, his singing quickly gained popularity.
In response, both officers and sailors hummed along with the melody, and the singing became louder and louder. In the engine room at the rear of the submarine, the chief engineer was shirtless and singing the song loudly.
Turn the switch of the sea valve.
On April 13, 1927, the last Japanese submarine was overtaken by a Federal Navy destroyer 30 nautical miles southeast of Jolo Island. After a seven-hour battle, the Japanese submarine was unable to escape the destroyer's tracking, and finally
Choosing to sink itself. As for why a submarine was driven out on the vast sea
The destroyer found it. The reason was neither that the sonar anti-submarine system on the destroyer was so advanced that it could search for submersible submarines in the sea at will, nor that the commander of the Japanese submarine made some fatal mistake and was exposed.
He knew his whereabouts, and the ultimate reason why it was discovered was the federal submarine.
When Kiichi Kaguyama's submarine chose to accelerate its turn and use the chaos of the Federation destroyer to launch deep-water bombs to escape from the encirclement, he did not know that behind his submarine, there were already two Orca-class submarines using underwater acoustic devices.
Efforts were made to detect its traces. Although affected by the noise from deep-water bombings and surface ships, the two ships
The sonar soldiers on the submarine firmly grasped the special sound frequency emitted by the Lu-23 submarine and followed it silently at a safe distance. Due to the unique silent motor of the Orca-class submarine,
It was so quiet that the sonar soldiers on the Kawasaki Kiichi submarine did not hear other ships following behind them.
The Orca-class submarine is a submarine manufactured by the Federal Navy specifically for anti-submarine warfare. Its design concept is different from other submarines. It neither designs a strong attack power nor emphasizes a large displacement, but is driven and detected.
A lot of effort has been put into the system. It is equipped with the most advanced sonar detection device in the Federation and the most advanced in the world. This sonar system can lock a fixed frequency and filter out as many sounds of other frequencies as possible, making the sonar soldiers
Enemies can be tracked based on this fixed frequency without being interfered by other noises.
In addition, the Orca-class submarine is also equipped with a powerful drive system. It uses three 6-cylinder diesel engines to drive 3 propellers, allowing the submarine to run at a speed of 20 knots on the water. Its electric motors are even more powerful, with 3 propellers.
If all are turned on at full power, the submarine can run at a high speed of 23 knots underwater. One of the electric
The motive is a specially designed silent motor. When tracking local ships or submarines, just turning on this motor can make the noise of the submarine at a very low level. Even the Federation's own marine sonar system dare not
Ensure that you can accurately capture this signal, especially in shallow sea areas.
Officially taking advantage of these characteristics of their own, the two killer whale-class submarines have been quietly following Kawasama Kiichi, and from time to time used towed antennas to send position information to federal surface ships. Only then did Kawasama Kiichi
The submarine was accurately caught by two destroyers in the vast sea while in submersible state. According to the current noise level of r this submarine
In addition, any ship equipped with a sonar system can easily catch it. Even if it stops and floats in the water, it cannot escape the active sonar detection of the Orca-class submarine. (To be continued. If you like this work,
