The water droplet-shaped bow is effortless to tear the sea water and sails smoothly. The trunk part of the hull with the best fluid mechanics silent design is in contact with the sea water, producing subtle navigation friction noise. Then the new silencer tile with a surface thickness of 200 mm is absorbed by the new noise silencer, making the friction noise of underwater navigation minimal.

Submarine noise sources are divided into three types: first, friction noise from underwater navigation, second, noise generated by internal mechanical devices, personnel and power systems, and third, noise generated by the rotation of the propeller.

The noise energy of the three noise sources, namely the decibel level, is determined by the submarine's own navigation speed.

The higher the submarine's underwater speed, the higher the noise decibels generated by the three noise sources, the easier it is to expose itself.

On the contrary, the lower the submarine's speed, the lower the noise decibels generated by the three noise sources, greatly increasing its own concealment.

The entire Jinling 093G has dropped from the initial 30 knots per hour to 18 knots per hour. All three major noise sources have dropped by two levels, reaching the level requirements of silent navigation mode.

Sail, advance.

Depth, 85 meters and continues to increase.

The high-performance bow combines passive sonar and left and right line array passive sonar to continuously obtain countless sound rhythms transmitted from the three-dimensional three-dimensional sea water space around it, identify and analyze, and check whether there are threatening military targets in the sound rhythm signal.

The seven-leaf large inclined propeller rotates clockwise at low speed, cutting sea water, giving the hull a strong forward push. The 093G, which is in silent navigation mode, is controlled by the steering wheel in the command cabin, the bow is slightly tilted forward, changing the navigation angle, and adjusting the hull. Then the surrounding simulated submarine environment provided by the fourth generation of terrain digital simulation system of the boat is accurately guided, and steadily arrives at the entrance of the Jeju Strait, facing the wide and huge submarine cracks.

The entrance to the Jeju Strait, 85 meters deep, is limited by the continental shelf environment and seawater salinity, and its visibility has dropped to zero and is in a state of being unable to see the five fingers.

It's pitch black.

Quiet.

This is an underwater environment that is difficult for patients with deep-sea phobia to accept.

In the command cabin.

"The current navigation depth is 90 meters, the seabed depth is 120 meters, and the speed is 17.5 knots. It has reached the entrance of the Jeju Strait. Vertically above the craft, there is a 50,000-ton ocean freighter sailing, about 45 kilometers away from the US Feiyang Island underwater monitoring station." Xu Guinian, the official, heard a low and clear voice, giving the current navigation status and surrounding data information.

On the main screen in the cabin, there is a digital analog environment for the undersea terrain. 093G has sailed through the entrance of the Jeju Strait and entered the interior of the strait.

Around the surroundings, a group of third shift operators worked hard and were on a alert state. The empty space behind the captain's battle position was standing with twelve people in the training team of all the awakened carrier aircraft.

"Command, put five miniature marine passive sonars into area No. 001, set the bottoming time, 30 minutes."

Lin Anlan heard the comprehensive information of the official report of the new official, nodded slightly, looked at the main screen with his eyes, and then issued an order. After saying that, a pair of deep eyes turned to the train-based aircraft team behind him. He raised his right hand and pointed his index finger at the map screen displayed on the right side of the main screen, and said slowly: "This is the familiar Jeju Strait. 126 years ago, the Japanese Navy Combined Fleet entered the Yellow Sea from here and started the Sino-Japanese War of 1894-1895."

Words are calm and natural, but they contain an indescribable feeling.

This feeling is like a hatred that has been suppressed in my heart for decades, and I cannot let go, but I have to bear it.

No, strictly speaking, one hundred and twenty-six years have passed.

In 1894, the Sino-Japanese War of 1894 broke out, and the Beiyang Navy was defeated in the Dadonggou Sea of ​​the Yellow Sea and its entire army was wiped out, a shame that could never be erased by historical records.

The deep and painful feeling of this shame is the most profound. As the successor, the Chinese Navy felt the most profound.

It was an era full of humiliation.

Some words came out and echoed in the huge command cabin and came into everyone's ears.

Suddenly, the atmosphere in the command cabin condensed and suddenly became quiet.

Sino-Japanese War of 1894-1895!

This extremely heavy word made everyone present tremble in their hearts, and their eyes couldn't help but follow the direction Lin Anlan pointed toward the main screen, looking at the navigation system map indicating the line markings of modern cutting-edge technology in the picture - Jeju Strait.

Xu Guinian, the official who obtained the order was retelling the execution of the value of the new officer, was stunned when he heard Lin Anlan's words, took a deep breath, and conveyed the captain's order to the weapon cabin through the boat sound element communication system, and prepared to release five miniature ocean passive sonars for monitoring and detection.

"In 1894, the Sino-Japanese War of 1895..."

Zhou Hai was speechless, just staring at the map indicators displayed on the main screen, and the key times and keywords mentioned in high school history class appeared in the depths of his mind. He recalled the detailed description of that humiliating history, and his mood couldn't help but feel ups and downs.

The whole person subconsciously clenched his fist with his right hand, then stretched it out, took a deep breath, remained calm, and avoided being affected by emotions.

Emotional fluctuations are the instinct of being a Chinese.

Staying calm is the basic requirement for being a pilot.

The Sino-Japanese War of 1894, which broke out in 1894, had a huge impact on China, allowing countries around the world to see clearly the seemingly tough but actually weak nature of the Qing government. At this point, it started a craze for invading and dividing China, causing China to fall into a semi-colonial and semi-feudal society.

This is the starting point of the modern and modern history of humiliation!

A word that can make any Chinese tremble.

The defeat in the Sino-Japanese War of 1894-1895 had a long impact on China, which was so far away that it was almost unimaginable. Even now, many people in China were kneeling on their knees, unable to raise their heads, straighten their waists, and unable to face people abroad.

These people have long been removed from their backs and can no longer have the idea of ​​resisting. In a sense, they can be called the "sick man of modern society."

"Look, this is the Jeju Strait, the place that once belonged to us. As a navy, every time I pass by here, I will think of the Sino-Japanese War of 126 years ago, and clearly feel the humiliation suffered by the Beiyang Navy and the entire nation. And I have only one meaning of this. I hope that as carrier-based aircraft pilots in the future, remember the humiliation and not forget the national humiliation - others can forget, but you cannot forget it."
