Open an aircraft carrier to fight against Japan

Lin Yuan said: "I will explain this to you later, please remember, don't sink them."

Han Mingguang didn't ask in detail, he knew that Lin Yuan would have a very important plan in the future, and he and his subordinates worked out a plan to lure Japanese warships.

It was April [-]th, at ten o'clock in the morning, the sea on the Bohai Sea was calm and there was no cloud, and the Beijing ship sailed quietly to Lushun Port.

Compared with Incheon Port, the Japanese army did not have too many warships in Lushun Port, because the Beiyang Navy had been completely wiped out by the British fleet.The warships here formed the Second Squadron of the United Fleet, which was responsible for monitoring the Qing army in the direction of Shandong and preventing the Qing army in Shandong from crossing the Bohai Strait, but no one believed that this would happen; after the failure of the second division's landing operation , The Second Squadron took on the task of protecting the landing force again.

In the Second Squadron at this time, most of the warships went to escort the landing troops, so the main battleships in Lushun Port were only Fuji and Shikishima, and two Asama-class cruisers. The cruiser ordered is equipped with two 3mm main guns in two units, fourteen 152mm rapid-fire guns, and two Yoshino-class cruisers. Japan appreciates the high-speed performance of this type of cruiser, so it ordered two more.

These two ships did not exist in Lin Yuan's era. One was named Kasuga and the other was named Ryujo. These two names were used by the Japanese Navy when it was first established. The Japanese Navy followed the habits of Western navies. , Take out the name of the ship that has been used and use it again.

The commander of the Second Squadron is Rear Admiral Togo Heihachiro. His promotion was because he made a big splash in the battle between the United Fleet and the Beijing ship. The Naniwa ship he commanded shot down an aircraft, but the high-level officials listed the aircraft as top secret, so The deeds of Togo Heihachiro are not known by too many people, so many people pointed at him for promotion to major general and said all kinds of ugly things.

Togo Heihachiro has always wanted to meet that mysterious ship again, sink it or capture it. When he heard that the aircraft appeared on the battlefield again and again, he instinctively realized that he was not far from the mysterious ship up.

The Japanese army established an observation position on the Laotieshan Fort outside Lushun Port, and they could observe ships fifteen miles away. In this era, the means of observation were extremely simple, only optical observation, and for ships, the easiest What they found was nothing more than the smoke from the chimney. The straight smoke column made every battleship nowhere to hide, but the Beijing ship was a nuclear-powered aircraft carrier, and the heat from the reactor was directly used to drive the propeller, so there was no smoke column.

When the Japanese observers on Laotieshan saw the Beijing ship, the Beijing ship was only eight nautical miles away from Lushun Port. The Japanese army quickly reported the news to Togo Heihachiro. Togo Heihachiro, who was eager to find the Peking ship, led six ships The warship sailed out of the port and headed in the direction of the Beijing ship!

The slowest Fuji and Yashima ships are in the middle, the two wings are the second-fastest Asami-class cruisers, Asama and Tokiwa, and the outermost are the two fastest Yoshino-class cruisers. Six Japanese warships line up Well, the distance between the two ships is about 1000 meters, which can suppress the opponent's possibility of turning and escaping to the greatest extent. The economic speed of the Beijing ship is 18 knots. Since the purpose is to lure the enemy, it is naturally impossible to travel at such a fast speed.

So the Peking ship moved forward slowly at a speed of 8 knots like a dying patient, which gave Dongxiang Heihachiro infinite confidence. He thought in his heart: "The mysterious ship is not omnipotent, it also has to follow everything. According to the laws of nature, as long as it is a mechanical product, it is impossible to have no faults, it seems that the mysterious ship has a fault this time."

At this time on the Beijing ship, navigation and radar have become the busiest departments. The electromagnetic waves emitted by the sea search radar are constantly changing the phase under the control of the computer, so as to complete the scanning of various parts of the space. This is the phased array. Radar, it can change the direction of electromagnetic wave emission without the mechanical movement of the transmitting antenna.

The electromagnetic wave emitted by the antenna has a shape, like a petal in space, and the strength of the echo is different in different positions, so the azimuth of the echo can be measured according to the strength of the echo, and then the Doppler effect can be used to The speed of the target is measured.

The Beijing warship quickly detected that six Japanese warships were heading towards them at a speed of 15 knots. If they continued, they would meet the Japanese warships in another 18 minutes. So Han Mingguang ordered the rudder to be turned, and the bow of the warship changed. 180 degree.

The turning of a ship is a very slow process, and the small boat is better. The inertia of the 500-ton ship Beijing is amazing. Although its rudder has been optimized, it can generate as much turning moment as possible. Beijing The turning diameter of the ship will still reach five times the length of the ship, which is more than [-] meters.

The diameter required for the bow to turn 180 degrees is an important indicator of the turning performance of a warship. It is generally [-] times the turning radius and is called the tactical diameter.

When the ship turns, the resistance increases, and the speed of the ship inevitably drops. Togo Heihachiro is keenly aware of the changes in the speed and direction of the Peking ship, and knowing that the Peking ship is about to flee, he immediately gives the order to chase at full speed. Give an order, the stoker on the battleship They tried their best to add coal to the boiler, Togo Heihachiro prayed silently, hoping to stop the Beijing ship before it turned the corner!

The sky was not according to one's wishes, and the Beijing ship turned a corner less than two nautical miles away from the Japanese warship.After the turn, the people in the navigation department immediately recorded the turn on the track map. Today's Beijing ship has no Beidou satellite navigation, no landmark positioning, and no radio positioning. The positioning method has returned to the most primitive Celestial navigation plus magnetic compass.

This navigation method is exactly the same as the Japanese warships tracking it on the opposite side. Dongxiang Heihachiro will be very relieved to know this.

In modern ships, especially warships, the status of celestial navigation has been greatly weakened compared to when it was born. Its biggest function is to correct the accuracy of the magnetic compass. Due to problems such as manufacturing and installation, the magnetic compass will An error is generated, and this error has been measured when the magnetic compass leaves the factory, and it is handed over to the user department in the form of a table.

However, the earth's magnetic field changes at any time. After a century of changes, the magnetic field in the 21st century is very different from that in the 18th century. Therefore, the calibration table at the factory can no longer be used, and astronomical navigation has become the only calibration method.At this moment, the speed of the four cruisers increased to [-] knots, and they were about to catch up with the mysterious ship!

Just when Togo Heihachiro's heart was beating in his throat, the Beijing ship suddenly accelerated. In just a few minutes, the speed increased from 8 knots to 19 knots.

Since the position of the fast cruiser is on both sides of the Beijing ship, a higher speed is needed to catch up with it, so the cruiser accelerated again and increased its speed to knots.

But their acceleration was not as good as that of the Beijing ship. When it accelerated, the Beijing ship opened a large distance from them.

Dongxiang Heihachiro turned his head and asked a gray-haired old man beside him: "Teacher, what do you think of this mysterious ship?"

The old man widened his eyes, shook his head and said, "This is impossible! There is such a boat!"
