In the North Atlantic in January, the weather is often rough sea. Pen "Fun" Pavilion www.biquge.info

Before the World War, the Imperial Chinese Navy was already the most powerful naval force in the world, allowing it to sail freely across the Atlantic Ocean and show off its force.

But at that time, there were also the American Navy's Two Ocean Fleet, the Royal Navy of the British Empire, and the Royal Navy of the French Empire in the Atlantic.

After the World War, the main force of the Chinese Imperial Navy successively destroyed the main forces of the Japanese Combined Fleet and the American Two Oceanic Fleet in the Pacific Ocean, and completely controlled the Pacific waters. Then the Pacific Fleet of the Imperial Chinese Navy could leave the Pacific Ocean and enter the Atlantic, and then raid Britain and control the British Royal Navy.

As a result, the capital ships of the Pacific Fleet of the Imperial Chinese Navy were incorporated into the battle sequence of the Atlantic Fleet, and from then on, the Atlantic Fleet of the Imperial Chinese Navy completely controlled the Atlantic, and even the High Seas Fleet of the German Empire did not dare to enter the Atlantic Ocean easily, fearing that the Atlantic Fleet of the Imperial Chinese Navy would be attacked by a surprise attack and lead to the annihilation of the entire army.

This is because, in the Atlantic, the German Imperial High Seas Fleet does not have any naval bases and strategic docking and supply points, and every time it enters the Atlantic, the German Imperial High Seas Fleet has to sail with a large number of supply ships, otherwise it will collapse due to lack of supplies.

But for the Imperial Chinese Navy, on the contrary, it was almost impossible to sail anywhere in the Atlantic without carrying a supply ship, because in and around the Atlantic, there were military bases of the Chinese Empire that could dock and resupply.

Most of these military bases in the Atlantic were taken over by the Chinese Empire from the British Empire, and some small European countries obediently handed over their colonies under the military deterrence of the Chinese Empire.

The Portuguese Empire was the most representative of this, which was in the Entente camp during the World War, and as the German Imperial Army invaded France, the Portuguese Empire felt that the Entente bloc was hopeless, so it sought forgiveness from the Allied bloc.

However, the German Empire at that time was already invincible on the European continent, and the iron hooves of the German army could soon destroy France, and then turn around and destroy the small Portuguese Empire, so Wilhelm II at that time rejected the Portuguese Empire's conditional surrender request.

Later, the Chinese Empire intervened in the European war in a timely manner, creating problems for the German Empire everywhere on the French issue, while sending troops to occupy Britain, deliberately leaving millions of British troops in France to make trouble for the German army, and then sending troops to seize the French island of Corsica.

The Portuguese Empire saw that the Chinese Empire was showing signs of confrontation with the German Empire, so it immediately appealed to the Chinese Empire for help. Although the Chinese Empire was dissatisfied with the fact that the Portuguese Empire had joined the Entente bloc, as the world pattern changed and the Entente collapsed, the next enemy of the Chinese Empire would become the German Empire, so in order to balance the German Empire and prevent small European countries like the Portuguese Empire from being annexed by the German Empire, it agreed to help the Portuguese Empire.

However, the Chinese Empire did not help in vain, and eventually forced the Portuguese Empire to transfer its colony of the Azov Islands in the North Atlantic to the Chinese Empire, which became an important naval base and transit supply base in the Atlantic Ocean for the Atlantic Fleet of the Chinese Imperial Navy.

The geographical location of the Azov archipelago is very important, especially its third largest island, Terceira, with an area of 400 square kilometers, there is a town on the island, as well as Angra Martísmo, there is a permanent population, where the people are mainly agricultural, can provide important food and fresh water supplies for the Chinese Imperial Navy, and open a naval base there, you can control the North Atlantic traffic lanes, the strategic location is extremely important.

In this way, the Chinese Empire acquired the Azov Islands, and then built fortifications and naval bases on the island of Terceira.

The Chinese Imperial Military expelled the aborigines of the island, and then immigrated here from within the Chinese Empire, turning Terceira Island and even the entire Azov Islands into an overseas territory of the Chinese Empire, on which only the citizens of the Chinese Empire live and live, ensuring the safety of the fortresses and naval bases above, and can call up the citizens of the Chinese Empire living on it at any time to guard the Azov Islands.

At the Terceira Island Heroic Port Naval Base, the Fifth Battleship Detachment, the Third Aircraft Carrier Formation, the Eighth Cruiser Formation, the Eleventh Destroyer Formation, and the Eighteenth Submarine Group of the Imperial Chinese Navy's Atlantic Fleet are permanently stationed here, patrolling the North Atlantic Ocean and maintaining the Imperial Chinese Navy's power presence in the region.

Half a year ago, the life of the officers and men of the Atlantic Fleet of the Chinese Empire on Terceira Island was still very comfortable, as the most powerful empire in the world, the Atlantic Fleet controlled the entire Atlantic, and even the German Imperial High Seas Fleet did not dare to come over, so on weekdays, the officers and men of the Atlantic Fleet just went out to sea as a routine patrol without any pressure.

However, after the first Chinese Imperial merchant ship was sunk by a mysterious submarine in the North Atlantic on its way to Britain, the officers and men of the Atlantic Fleet of the Chinese Imperial Navy began to be nervously busy, and when the second Chinese Imperial merchant ship was sunk, they were greatly shocked, and the detachments quickly dispatched to search for the mysterious submarine in the vast North Atlantic.

Unfortunately, instead of finding the other side, an anti-submarine destroyer was sunk again.

At this moment, the officers and men of the Atlantic Fleet of the entire Chinese Imperial Navy, from top to bottom, were not calm.

"It's all rubbish!"

"Sink that damn German submarine, or don't come back!"

The commander of the base on Terceira Island roared like this every day, scolding a group of his men, and then driving them all out to hunt down German submarines.

All the warships in the entire Sanshero Harbor have left the port, and a new day of manhunting has begun.

However, the officers and soldiers were not confident, after all, if the mysterious potential of the German army was nearby, then their anti-submarine sonar should have discovered the other side long ago. However, nothing was found at all, one may be that the other party is not nearby at all, and the other may be that the sonar cannot detect the other party's location.

Obviously, the officers and men of the Chinese Imperial Navy did not dare to believe the latter, after all, in their hearts, the equipment of the Chinese Empire was always the most advanced.

The 11th destroyer formation was also in action, and as usual, the 20 destroyers of the 11th destroyer formation were divided into ten groups and two destroyers in a group to carry out escort and search missions in the predetermined sea area.

Today, the last group is a little special, because the Sea Eagle 328 ship came up with a naval cadet intern, his identity is the thirty-first prince of the Chinese Empire, Keqin, who has just turned eighteen years old this year, according to the regulations of the Chinese Imperial Family, the eighteen-year-old prince will be released to serve in the army for two years, which is regarded as the assessment period, and after two years, according to the assessment results, it will be decided by the Chinese Emperor Li Weiguo whether to give the title of king, and the prince with the best performance is eligible to get the title of one-word king, followed by the two-word king, and then the multi-word king, The latter were basically sent to the vassal states to take charge of local military affairs.

Of course, there is also the most unsuccessful prince, who does not have any title and is not qualified to serve in the Chinese Imperial Army, and can only live an ordinary life as a rich man.

Prince Keqin is the queen of the main palace Fu Shanxiang, is her youngest child, can be described as the second generation of the emperor, if there is hope to be crowned the king, the future will also have the right to inherit the throne, so it has attracted much attention at home and abroad.

However, the official reply of the Chinese Empire was that Prince Keqin would serve in the Pacific Fleet, which was the same as the majority of media speculation, but in fact, Prince Keqin secretly arrived at the Atlantic Fleet and was assigned to serve in the 11th Destroyer Fleet at Terceira Island Naval Base.

The identity of Prince Keqin is only a trainee staff officer, temporarily acting as the second deputy.

No one knew the identity of Prince Keqin, except for Tan Lin, the captain of the Sea Eagle 328 ship, because he was Prince Keqin's direct boss and had the right to view Prince Keqin's archives, so he knew everything.

Although the Office of the Minister of the Imperial Guard of the Chinese Empire had told Tan Lin not to discriminate and to treat everyone equally, for Tan Lin, he could not treat Prince Keqin as an equal like everyone else. Because after all, it is the concubine of the queen of the dynasty, and if something happens, she will inevitably be affected.

Of course, in the Chinese Empire, there are also many rumors that every prince's military experience means that the prince's circle of friends will be established, and if the prince succeeds to the throne in the future, then his circle of friends will be a situation of "chicken and dog soaring".

So when Tan Lin learned the identity of Prince Keqin, he inevitably had no idea, and often called Prince Keqin to his side for questioning and expressing his closeness.

"Comrade Xiao Li, I heard that you are studying anti-submarine tactics?"

Prince Keqin nodded and said, "Report sir, the humble post is indeed studying an anti-submarine warfare topic, and if it can be successful, it is expected to greatly improve the combat capability of our anti-submarine destroyers." ”

Since the Chinese Imperial Shence Army obeyed the orders of the imperial family, the princes' careers were almost doomed, and they needed to serve in the army to ensure that the army was always in the hands of the imperial family. The imperial family can ignore state affairs, but it cannot give up military power, which is the means left by Li Weiguo for his descendants to save their lives, to prevent the tragedy of the change of ancient Chinese dynasties and the destruction of the royal family from repeating in the descendants of the Li family.

Prince Keqin studied at the Imperial Naval Academy, and in order to prepare for his graduation thesis, his topic was anti-submarine warfare, and he made a new breakthrough in this area.

Tan Lin suddenly became interested when he heard this, and hurriedly asked, "Are you saying that you can find that German mysterious submarine?" ”

Prince Keqin nodded and said, "I am working on a new type of sonar array, and if it is successful, I think there should be no problem in catching that German submarine." ”

Tan Lin instantly became excited, and said hurriedly: "What do you need, I'll let someone help you!" ”

Regarding the sonar research of Prince Keqin, although Tan Lin was excited on the surface, he still didn't believe it in his heart. In his opinion, the prince came down to practice, and he came down to gild, and then went back and was directly promoted. Tan Lin was really a little surprised by the princes' research and felt a little empty.

It's just that seeing Prince Keqin's serious expression, Tan Lin didn't dare to be sure in his heart, and he just regarded it as a favor for the prince.

But soon Tan Lin was not calm, and he sent his subordinates to help Prince Keqin come back to report, showing that Prince Keqin was indeed working on a new sonar array to improve the ability to detect underwater submarines.

So Tan Lin came to Prince Keqin again to watch him engage in those strange equipment.

"Comrade Xiao Li, what kind of equipment are you? It feels weird! ”

Prince Keqin then explained: "I call this thing a sonar array, on the basis of the original sonar, to sweep away the detection blind spots, avoid the source of noise, this will greatly increase the probability of detecting enemy submarines." ”

Tan Lin asked, "You mean that your sonar array can even detect blind spots?" ”

Prince Keqin explained: "Theoretically, this is so. Because our sonar device is installed at the bottom of the battleship, the sonar sounding device will be disturbed by the current of the hull, and some are even close to the position of the propeller, when the propeller rotates at high speed, the resulting torrent will emit a lot of noise, affecting the judgment of the sonar soldier. ”

Tan Lin surprisingly agreed, and asked rhetorically, "Then how did your sonar array solve this problem?" ”

Prince Keqin explained: "My sonar array was inspired by the surgical lamp, if it is only one lamp, then there will be a situation of darkness under the lamp, and the surgical lamp is to use a group of lights to shine in different directions, thus solving the problem of darkness under the lamp." That's how my sonar array works, where the blind spots created by one sonar device are filled with another. ”

Tan Lin understood, but shook his head and said: "Your proposal is very good, but have you thought about it, if multiple sonar detection equipment is installed at the bottom of the battleship, it will seriously affect the speed of the ship, after all, every sonar equipment needs a raised part to place." ”

Prince Keqin said: "So I have another way, which is to make a separate sonar array, place multiple groups of sonar devices in it, and then use the towing method to drag forward behind the battleship, so as to avoid the interference of hull noise, and you can hear the underwater sound more clearly." ”

"Drag the sonar individually, it's very good! This offer is very good! Tan Lin couldn't stop nodding, as if the endless darkness suddenly lit up, making him suddenly brightened.

As the captain of a destroyer, anti-submarine warfare is the most important thing, and whether or not you can hear clearly the voices below the surface of the sea is related to the success or failure of anti-submarine warfare.

The previous design of the Sea Hawk-class anti-submarine destroyer made the sonar device have a design blind spot, and the speed of the anti-submarine destroyer is very fast, and the propeller noise makes the sonar soldiers unable to hear other sounds under the sea surface many times, which has a serious impact on anti-submarine warfare.

However, if the drag-and-drop sonar method is used, these problems are well avoided.

Nowadays, the search for the German mysterious submarine is regarded as the highest priority, and whoever finds the submarine first will be a great achievement.

Tan Lin, who is eager to make meritorious contributions, will naturally not let go of such a good opportunity.

"Comrade Xiao Li, just follow your idea, let's try it once!"
