Open an aircraft carrier to fight against Japan

When the news came back to the Beijing ship, Lin Yuan was inspecting various departments of the Beijing ship. He saw a scene that surprised him through an open door.

The four soldiers on duty, under the leadership of the company commander, are playing games with relish!

The company commander was wearing earphones, and while clicking the mouse, he loudly commanded the soldiers under him. A sharp-eyed soldier spotted Lin Yuan, immediately put down the mouse, stood up, the company commander didn't realize it, and shouted Calling the soldier's name, he said angrily, "Hey, why don't you move! We're going to lose!"

The company commander also found Lin Yuan at this time, he quickly stood up and said: "Report, report to the captain, I am leading the soldiers to test the performance of the computer!"

Lin Yuan chuckled and said, "What performance are you testing?"

The company commander said: "Report Captain, we are testing the performance of the graphics card! We have maximized the graphics quality of this so-called graphics card killer game! All kinds of special effects are fully activated! The frame rate of the picture exceeds [-]! The performance of the graphics card is completely qualified!"

Lin Yuan glanced at the name tag on his chest, and asked with a smile, "Your name is Li Kai?"

Li Kai straightened his chest and said, "Yes!"

Lin Yuan said, "In the drone department?"

Li Kai said, "Yes!"

Lin Yuan said, "Why do you play games while on duty?"

Li Kai said loudly: "I promise there will be no next time!"

Lin Yuan asked: "Let me ask you, how many kinds of drones are equipped on the Beijing ship?"

Li Kai said: "Three types, the first type: wr-30, powered by solar energy, is a high-altitude long-endurance strategic drone that can be used for strategic reconnaissance and relay communication command; the second type: wr-, is Conventionally powered unmanned reconnaissance aircraft; the third type: wr-11, used for reconnaissance and monitoring at the tactical level."

Lin Yuan said, "Do you play games because you feel that you have nothing to do when you are free?"

Li Kai nodded unwillingly, and Lin Yuan said, "You guys will be very busy soon!"

After Lin Yuan finished speaking, he turned and left. When he reached the door, he turned around and said to him, "You, write a [-]-word self-criticism and hand it over to your superior!"

At this time, Lin Yuan received Zhang Hua's analysis, and he immediately decided to speed up the construction of the new fleet.

Lin Yuan's idea is: In possible future wars, the aircraft carrier will not directly undertake the attack mission because its weapons and equipment cannot be supplemented, but will serve as the center of the command, control, reconnaissance and surveillance of the entire fleet, using the equipment on the Beijing ship. The unmanned aerial vehicle conducts target search on a certain sea area to achieve the purpose of discovering the enemy first. On the battlefield, the calibration of the unmanned aerial vehicle is used to achieve more accurate shooting!

It is common practice to use UAVs for ground artillery reconnaissance and calibration, but no one has ever used UAVs for naval artillery!The reason is also very simple: when drones appeared, the navy had already passed the era of decisive victory of cannons and giant ships.

On the morning of December 1894, 12, Deng Shichang led the first batch of trained artillery operators and boarded the captured Japanese warship Yoshino. In the Toshima naval battle, it was the Yoshino ship that fired the first shot. In history, Deng Shichang's Zhiyuan ship was also sunk under the attack of the Yoshino ship, but now, the Yoshino ship has begun to serve the Chinese.

The Yoshino ship was also an excellent cruiser at the time. It could reach a speed of 23 knots under forced ventilation and was equipped with rapid-fire guns.

On the current Yoshino ship, some are artillery operators trained by Deng Shichang, some are engineers and navigators trained by Beijing ship, and some are Beijing ship personnel with advanced communication and ranging equipment. Deng Shichang said that the distance can be accurately measured because of the portable laser range finder on the Beijing ship.

This morning, on the surface of the East China Sea, with a wind speed of 2.3 meters and a wave height of 0.2 meters, a wr-30 drone took the lead to take off and served as a relay command mission over the Beijing ship!Subsequently, a wr-11 tactical unmanned reconnaissance aircraft took off.

In the 21st century, the role of drones in warfare has always been the focus of military theorists. Because there are no people, drones can undertake many extremely dangerous tasks. Even if there are losses, they don’t have to bear casualties— —the consequences of which will cause enormous social pressure.

Although the application of drones in warfare can be traced back to 1914, it was not until 100 years later, 13 years later, that drones took off and landed on aircraft carriers. In addition to military theory, there are also technical difficulties. .

Drones cannot handle emergencies as quickly as manned machines. Drones can think like humans. This kind of thing only exists in science fiction. During the process of take-off and landing, many accidents may occur. These accidents It is impossible to program all drones, and it is difficult for controllers to deal with accidents in a very short period of time.

What is even more dangerous is the landing process. When the manned aircraft lands on the ship and aligns with the runway and adjusts the altitude, it is controlled by humans, while the drone needs to be controlled by the controller after observing the situation, which will delay After a long period of time, if the interception hook does not hang on the interception cable, this situation is also very common on manned aircraft. The pilot of the manned aircraft can immediately choose to accelerate the go-around, but the UAV has to do so if it wants to do so. There may be situations where it is too late.

The reason why the Beijing ship is equipped with many drones is that it hopes to use drones to explore the application of drones in naval warfare in future wars. Unexpectedly, they came in handy after crossing.

Imagination is always beautiful. The first subject is the discovery of sea targets by wr-30. The target is the 30-ton displacement ship Hashidate. Lin Yuan is standing beside Li Kai at this time. Staring at the image sent back by wr-[-], hoping to find the target.

The automation of our army's aerial reconnaissance has been greatly improved. The original reconnaissance required a process of photography, film processing, photo printing, and visual interpretation. On the modernized Beijing ship, this series of processes are completed by computers, and target interpreters only need to observe the target.

The real-time image of the sea target is transmitted back to the Beijing ship, and the computer on the Beijing ship processes the series of 0s and 1s at high speed, performs image enhancement, edge processing, noise removal and other processes, and processes the image into a picture suitable for personnel to watch , that WR-30 flies at an altitude of 5000 meters and can monitor an area of ​​15 square kilometers. After a series of image segmentation and feature extraction, the computer has already distinguished the targets that may be ships.

But the computer can't know which are enemy ships and which are civilian ships. Therefore, personnel must judge. Li Kai and his soldiers stared at the screen closely. With a square of centimeters and such clarity, the size of a photo may exceed tens of grams, so processing such a picture places extremely high demands on the computer's processor and graphics card.

Li Kai dragged the picture, looking for possible targets. There was no lag in the picture when dragging. Li Kai followed the target characteristics of the Hashidate ship, screened one target at a time, and finally locked on the target.

Lin Yuan looked at the coordinate information sent back by the Hashidate ship, and gave Li Kai a signal that he had judged correctly. Deng Shichang drove the Yoshino ship to the target sea area quickly. Unexpectedly, he found a big problem during the target calibration.
