Just when the world was hotly discussing the secret war between China and Britain, two months later, the Ministry of War had held a military meeting to investigate the North Sea submarine collision accident and recalled the captain and sailor of the Blackhead Shark submarine. Even Chen Shaoyi was recalled and spoke in the conference room of the Ministry of War, summarizing the lessons and experience of the accident, and striving to avoid similar situations in the future.

According to the statement of the Blackhead Shark Captain, the underwater collision was due to the lack of underwater detection equipment. When the Great White Shark class submarine was sailing underwater, it was completely dark and could not see anything. It was entirely based on the prepared nautical chart. It was completely unknown what was outside the submarine. The captain said that he had bumped into a giant octopus in the Atlantic Ocean and was almost preyed by the octopus.

This incident attracted the attention of military personnel from the Ministry of War, and the military industry department was required to study equipment that could allow submarines to be underwater and not blind, so as to avoid similar accidents from happening again.

Since the Chinese Empire did not have many submarines and had been taking high-quality routes before, the loss of a great white shark-class submarine is a very important matter for the power of the Chinese Empire's naval submarine.

Fortunately, the Naval Defense Act of the 3980 Yuan Dynasty of the Chinese Empire has been implemented for more than a year. The first batch of 24 new submarines are in full swing. The first batch of 12 submarines have been completed. The final sea trial is currently underway. The installation is completed and it can be officially put into service. Therefore, the sinking of the Blackhead Shark this time has only one or two months of adverse impact on the Chinese Empire Navy. The military did not hold it too much accountable and soon ended the military hearing.

At the subsequent congressional hearing, there were no difficulties in the captains and sailors of the Blackhead Shark submarine.

Of course, this is not the generosity of the MPs, who suddenly changed their minds. These MPs are elected nationwide and are very concerned about any unexpected losses of economic property, especially large military equipment losses. This time, because the Chinese Empire filed a solemn protest to the British Empire, deliberately used the Blackhead Shark to blackmail the British Empire, and received an apology and double compensation from the British Empire. In fact, the Chinese Empire did not suffer any losses, but instead made a profit in politics and economic terms. Therefore, these MPs easily let the Blackhead Shark out of their personnel.

However, when the military handed over the final discussion to Emperor Li Weiguo Yulan, Li Weiguo suddenly realized a problem.

Submarines are blind underwater, and this problem is not impossible to solve. You only need to develop sonar detection equipment.

Before, Li Weiguo took the lead in developing submarine power and considered sonar detection equipment, but because the technology in the 1870s was insufficient, it could not meet the development of sonar detection equipment.

But now it is different. After entering the 1980s, the Chinese Empire was leading the world in the telecommunications industry, and telephone and radio systems have been successfully developed.

In this way, early sonar systems based on telephone and radio systems will no longer have technical obstacles and can be developed quickly.

So Li Weiguo called the military and relevant experts in the field of telecommunications to study the solution to overcome the submarine underwater without blind people.

"The principle of this sonar system is very simple. We say that the bat's eyes cannot see, but it can fly around obstacles. Why? Because the bat has a set of radar equipment that can emit electromagnetic waves into the surrounding air. When the electromagnetic wave hits the obstacle, it returns to the bat, so the bat knows that there is an obstacle in front of it and avoids it."

At the meeting, Li Weiguo briefly introduced the principles of the sonar system to everyone, and he showed off his crazy sex again, which made all the people present admire him.

"Your Majesty means that we can emit electromagnetic waves underwater and use the electromagnetic waves to return time to calculate whether there are obstacles ahead?" asked Meuqi, an expert from the Ministry of Telecommunications, and expressed his own understanding.

"Your basic idea is correct! But the electromagnetic waves decay too quickly underwater, and the detection distance is only a few dozen meters, which has no effect."

Li Weiguo nodded, first affirming Meiwuqi's understanding, and then added: "The sonar system I mentioned first uses the principle of sound wave transmission. The sound attenuation is low underwater and the propagation distance is long. A shell here explodes, and sound wave signals can be detected underwater 20,000 kilometers away."

Deppler, an expert from the radio group, suddenly asked: "Your Majesty, our radio is electromagnetic waves. Since you deny the use of electromagnetic waves, what is the purpose of asking our radio group to come?"

Li Weiguo smiled and said: "The radio transmission capacity underwater is limited, but if you build a sonar basic array, it depends on the cooperation of your radio group. You need to convert the radio basic array into a sonar basic array."

Deppler immediately understood, and finally let go of his heart.

Meuchi asked again: "The sonar array is the responsibility of the radio group, so what is our telecommunications group responsible?"

Li Weiguo then said: "Your telecommunications group is responsible for the most important transducer! This transducer is the core equipment of sonar and has two functions. One is to transmit transducer, as the name implies, it is a device that emits sound waves, similar to the receiver or speaker in the telephone you developed. However, this time it does not spread sound in the air, but underwater. The other is to receive transducer, which is equivalent to the sound cylinder or microphone of the telephone. It also needs to receive sound underwater. The higher the sensitivity, the better."

"I understand!" Meiwuqi agreed happily. He felt that there was no problem. He just needed to change the components of the telephone system so that it could be used underwater.

Li Weiguo nodded and said, "According to this idea, start developing the sonar system first! If you have any questions at that time, you can ask me at any time!"

At the order of Li Weiguo, the Imperial Academy of Sciences established a sonar research team and began intensive development and experiment work.

The most core component of the sonar system is the transducer, but now there is no problem for the Chinese Empire.

With a large population and a strong force, with the support of the Imperial Academy of Sciences, the sonar team completed the first sonar system in less than three days, and then found a pool to start the experiment.

The testers put on their headphones, listened to the echo of the pool, and then calculated the depth of the pool based on the water density and echo time. At first, the error was very large, but after several tests, the error gradually decreased.

The personnel of the sonar team immediately felt energetic, indicating that their direction of efforts was correct. The next step was to continuously improve and improve the entire sonar system, and finally install it on the submarine and warship. So they also found ship designers Wei Han, Holland and others to work together to study the situation and finally install the sonar system in which position is most suitable.

All research on the sonar system is progressing smoothly. Li Weiguo believes that within a year, the sonar system will be completely improved and then equipped for the navy. At that time, the submarine will not easily hit the Shanghai ridge trench or other submarines underwater.

At the same time, Li Weiguo also thought of anti-submarine destroyers. Previously, anti-submarine destroyers only had deep-water bombs as anti-submarine weapons, but actually had no detection capabilities. It all depends on the speed of destroyers. It often takes a long time to search for enemy submarines on the sea surface. After all, the enemy's submarine can submarine for more than a few hours. Anti-submarine destroyers must search for enemy submarines within a large anti-submarine radius, which is time-consuming and labor-intensive.

Now there is a sonar system soon. If anti-submarine destroyers are also installed, you can easily discover enemy submarines under the sea.

Of course, although there is no problem in the development of sonar systems in this era, the accuracy is not very high. After all, many electronic components have limited technology.

However, relatively speaking, submarines of this era are also very simple. After all, submarines of this era can only dive for about 50 meters deep, and can be seen with the naked eye in good light. The noise of submarine propellers is also very loud, and people can feel it with their ears underwater within one kilometer.

In this way, even the sonar with low accuracy can easily capture the echoes of the submarine and the huge propeller noise of the submarine.

This principle is like two people playing chess. If they are both bad chess, then both of them will think that the other party is very powerful.

Therefore, Li Weiguo could imagine that when the submarines of the Chinese Empire had sonar systems, the enemy's submarines would be hunted by their own side underwater. Anti-submarine destroyers had sonar systems, and the enemy's submarines would have no way to escape. With the sonar systems of various main warships, the enemy's submarines would be discovered before they got close. The large-caliber main guns bombarded and instantly killed the enemy's submarines that came to attack.

Li Weiguo was immediately happy. This was another killer equipment!

Now the Chinese Empire has many killer weapons and equipment. In the future, even if Britain, France, the United States, Russia and Japan are united in full, the Chinese Empire will not be afraid of them. They will definitely fight them all over the ground and fight them out!

Time passed day by day, and the whole world appeared to be peaceful, but in fact it was undercurrent.

The military group led by Britain, the United States, Japan and Germany, the German and Austrian military group and the Chinese Empire have never stopped.

Since more than a dozen submarines of the British Navy were secretly killed by the Chinese Empire submarine Blackhead Shark a few months ago, the British Navy suffered a loss. Now, the British Empire has not only not been scared, but has increased its efforts in submarine secret combat.

The British submarines were no longer limited to the Atlantic Ocean and Indian Ocean, but quietly entered the Pacific Ocean. Britain still had several strongholds in the Pacific Ocean, namely New Zealand and the Solomon Islands near Australia, which were still under the colonial rule of the British Empire.

The British Navy built defensive fortifications and naval bases on a large scale here, and a large number of British submarines were deployed here, secretly harassed the merchant ships of the Chinese Empire, secretly tracked the warships of the Chinese Empire, and secretly practiced attacks on the warships of the Chinese Empire.

The British intelligence department was closely watching the submarine forces of the Chinese Empire. Whenever the submarines of the Chinese Empire left the port, the British submarines also left the port, and the two sides continued to compete under the sea.

This has almost become a tacit understanding between the Chinese Empire and the British Empire. Neither side will pursue the other party's attack. No matter whose submarine is sunk, it will claim that the submarine is sunk due to an accident. If there are surviving sailors, they will be strictly controlled and no secrets are allowed.

Overall, the submarine forces of the Chinese Empire won more than lose, while the submarine forces of the British Empire suffered heavy losses.

However, the British Empire still had no intention of retreating and continued to invest more submarines. In fact, this is the British Navy strengthening the combat effectiveness of British submarines through actual combat, and is also analyzing the submarine performance and advancedness of the Chinese Empire, and working hard to surpass the submarine forces of the Chinese Empire in the future.

At the same time, the British Empire also gathered submarine forces from the United States and the Japanese Empire, and the three submarines were hunting the Chinese Empire's submarines under the Pacific Ocean.

For a time, the entire Pacific Ocean became a slaughterhouse, with a large number of British, American and Japanese submarines sunk, while the Chinese Empire's submarines were rarely lost.

Media around the world soon noticed that almost every week, submarines from Britain, the United States, Japan and Japan would sink, while the Chinese Empire would only have a submarine accident every six months.

Everyone understands that this is another underwater battle between Britain, the United States and Japan against the Chinese Empire!

However, a year later, as various types of warships of the Imperial Empire Navy returned to the dock for overhaul, after the restoration and discharge of the dock, in just one month, the number of submarines crashed in the Pacific Ocean by Britain, the United States and Japan exceeded 100, while the Imperial Empire Navy's submarines suffered no losses.

The whole world was shocked. The submarines of Britain, the United States and Japan were almost slaughtered one-sidedly!

In just one month, the submarine troops of Britain, the United States and Japan in the Pacific Ocean were almost wiped out!

So, the leaders of Britain, the United States and Japan who learned about this immediately vomited three liters of blood!

On March 4, 1882, representatives of the British, American and Japanese sides met in Washington. Faced with the recent operations of the Three Kingdoms Navy submarine forces, the three sides collectively agreed to suspend all submarines' missions to conduct missions to investigate the cause of the "accident".

This was also a decision that was forced to be made. Although people all over the world understood that the United Kingdom, the United States and Japan lost 100 submarines in one month, which was clearly tortured by the Imperial Navy!

However, this is a hidden rule. The British, American and Japanese governments know their own suffering, but they cannot tell them. They suffer losses and suffer losses.

Faced with public opinion around the world, the British, American and Japanese governments have to shamelessly say that it was an "accident" caused by submarine quality problems. Currently, an investigation is filed to hold the submarine manufacturer accountable.

As a result, all submarine manufacturers in the United Kingdom, the United States and Japan were shot and were summoned by the three parties, and then imposed huge fines.

The submarine manufacturers of the Three Kingdoms immediately scolded the military for being shameless and asked them to take the blame. Unfortunately, their arms could not be twisted, and the people could not fight against the officials, so they could only suffer in silence.

However, the Navy of Britain, the United States and Japan cannot suffer such a big loss in vain.

The three parties decided to cooperate in submarine technology and jointly develop advanced submarines to fight against the submarine advantages of the Chinese Empire.
Chapter completed!
