In the naval war, after China pioneered the use of submarines, other countries also joined in, especially Germany, which was very unique in the application of submarines. After the outbreak of the war, the main force of the German Navy was blocked in the port by the British Navy, but the submarines of the German Navy often entered the ocean, causing great losses to the British sea transportation lines, and the total tonnage of British merchant ships sunk every month reached more than 100,000 tons. Even though the British Navy thought of many ways to deal with German submarines, until now, there was no good way, which was mainly constrained by the fact that there were too few ways to attack submarines.

If you want to sink a submarine, you have to discover it first. However, when a submarine is diving, it is generally under water tens of meters deep, and it is very difficult to find the traces of the submarine. Only when the submarine launches an attack will the traces be revealed. And at this time, the escort warships will swarm away and attack the underwater submarine with naval guns or depth charges. The shell of a submarine is relatively thin, and both naval guns and depth charges can cause fatal damage to it. Once the shell is broken, there is a high risk that it will sink into the sea and never float again.

To detect underwater submarines, you need to use some special equipment, such as sonar, which is the best equipment for detecting underwater submarines. When China began to apply submarines to naval warfare, it also began to develop countermeasures. Back in 1906, the British Navy's Lewis . Nexon invented sonar, which can only be heard passively and belongs to passive sonar. Overseas agents of the Military Intelligence Agency have managed to obtain relevant technology. The Chinese Academy of Sciences also organizes experts. It has been studied and upgraded in more depth, and research on active sonar has begun on this project, which has achieved breakthrough success and will soon be able to be put into practice. At that time, the destroyers and cruisers of the Chinese Navy will be equipped with such sonars. (Historically, in 1915, French physicist Paul Langevin collaborated with Russian electrical engineer Inchilowski to invent the first active sonar device for detecting submarines.) ）

"Your Majesty, what do you want from this kind of frigate?" Minister of the Navy Zhang Cheng said. Wang Yuze asked the Navy to build frigates, but Zhang Cheng had no problem with this. Submarines are playing an increasingly important role in naval warfare, and at the same time the threat to the Chinese Navy is also increasing. It's also very nice.

"The frigate should have professional equipment to deal with submarines. In addition, it should be fast, low cost, and can be built on a large scale! Wang Yuze said. When the time comes to defeat the Entente and compete with Germany for world hegemony, the Chinese Navy will have to face the submarines of the German Navy. When the time comes. A sufficient number of frigates can ensure the safety of various sea transportation routes, and can also provide underwater security for the fleets of the Navy, especially the aircraft carrier fleet.

"Yes, Your Majesty!" Zhang Cheng nodded, and immediately asked the designers of the shipyard to design the battleship according to Wang Yuze's requirements after returning to the Admiralty. He already understood what Wang Yuze meant, the main function of this kind of frigate is anti-submarine, and its own sea attack and protection will not have too many requirements. That's the case. It can effectively reduce the cost of warships.

"Your Majesty, yesterday the German side contacted us again and wanted to buy our production technology for tanks and armored vehicles!" Chief of the General Staff Cai Yun said. Although the Chinese had politely rejected Germany before, the Germans did not seem to be completely dead.

"Ignore them! Armored forces are the killer weapon of our army. The Germans can't be let take it so cheaply. The German Army is already strong enough, and it will be even more difficult to deal with if it has more armored forces. However, with the industrial strength of Germany. It is not very difficult to develop tanks and armored vehicles. It's just that the performance won't be too good at first! Wang Yuze said. Germany's total industrial output is probably not as large as that of the United States. But Germany's research capabilities are much stronger than those of the United States.

"Yes, Your Majesty! In addition, the German side wants to flank Russia with us! The Germans were exhausted on the Western Front by the Anglo-French forces. In addition, the appearance of Austria-Hungary as an ally was so poor that Germany had to deploy some troops on the Eastern Front and could not concentrate all its efforts against the Anglo-French forces. At a time when there was no hope of a quick victory on the Western Front, the German General Staff proposed a plan to change its strategy, defeating Russia first, and then dealing with Britain and France. However, it will take our cooperation! Chief of the General Staff Cai Yun said. The Western Front of the European War has completely become a trench war, and both sides have built a large number of trenches and fortresses to confront each other, and in order to overcome these trenches, both sides have paid a heavy price, and tens of thousands of people die in trench warfare every day. Although Germany still had the upper hand, which cost the Anglo-French army dearly, it was also exhausted.

"Flanking Russia? The Germans couldn't hold out? On the German side, our main focus now is on the United States, and we can't spare troops to cooperate with Germany for the time being! Wang Yuze said. Although Germany is fighting very hard now, Germany's national strength is still there, far from reaching the point where Wang Yuze wants to use the Entente to consume Germany's national strength. Therefore, it is very disadvantageous for China to intervene in the European war at this time. Besides, the war against the United States has now entered a critical moment. The next step is to invade the United States. China needs to focus its main efforts on the Americas theater. Only after defeating the United States and completely obliterating this great enemy will China have enough energy to deal with threats from other directions.

"Yes, Your Majesty! But this will not displease the Germans. What if the Germans were not willing to lose both with the Entente and deny us the opportunity to reap the benefits? Cai Yun said. Although China wants to be a fisherman, it will put the Allied and Entente countries in contention. But neither the Allies nor the Entente are fools, and once they realize that it is impossible to win each other on the battlefield, and that they will also give China the opportunity to dominate the world, they are likely to resort to other means.

"That's what we need to get right. Progress on the American battlefield needs to be accelerated, preferably with the destruction of the United States by the end of next year. Our support for Germany cannot be stopped, and we can increase the volume of the Baghdad railway. In addition, the decisive battle between the German Navy and the British Navy has not yet begun, and Wilhelm II will not give up his dream of world domination so lightly! Wang Yuze said. In order to compete with Britain for world supremacy, Germany gritted its teeth and built a powerful navy. If the German navy could defeat the British navy, then the predicament facing Germany would be lifted, and even Britain would be forced to withdraw from the war in one fell swoop. At that time, France will also be on its own, and Germany will become the hegemon of Europe. At that time, Germany, which has obtained the resources of the whole of Europe, will have enough strength to compete with China for the ownership of world hegemony.

"Your Majesty, the German 'Bavaria-class' battleships have been commissioned and are now undergoing intensive training. The Admiralty expected that the Germans would engage in a decisive battle with the British Navy at the end of next month or early next month. This will also have a great impact on Germany's future strategy. If the German Navy had been able to win, Germany would have continued the war. If the German Navy had not won for Germany, then Germany's determination to fight would have been shaken! Navy Minister Zhang Cheng said.

"What does the Admiralty think of this decisive battle?" Wang Yuze asked, in the Battle of Jutland in history, the German navy won a tactical victory, and its own losses were much smaller than those of the British navy. But the British Navy won a strategic victory. After the naval battle, the German navy remained locked in the military port until the end of the war. But this era was different, and the German navy was much stronger than it was in history. Especially now that the German Navy's 'Bavaria-class' battleships are in service, but the British 'Elizabeth II-class' battleships are still under construction, which gives the German Navy an excellent opportunity.

"Your Majesty, the Admiralty conducted a war game and came to the conclusion that the German and British navies were likely to lose both. The German Navy had 29 battleships and 8 battlecruisers. The British Navy had 35 battleships and 10 battlecruisers. In addition, the British Navy has five Elizabeth II-class battleships and five 'Revenge-class' battleships under construction. Even if the German navy was able to gain some superiority in naval warfare, they could not defeat the British navy. Once the British Navy's 'Elizabeth II-class' and 'Revenge-class' battleships were commissioned, the German Navy had no advantage. Defeated by the British Navy, there will be no doubts! Navy Minister Zhang Cheng said.

The German Navy's battleships were generally more powerful than the British Navy's battleships, which were designed to sacrifice protection for greater speed and firepower. The battleships of the German Navy attached great importance to the protection of their warships, and their resistance to strikes was much stronger than that of the battleships of the British Navy. It's just that the British Navy has a numerical advantage, and the British Navy is even higher, and the British Navy, which has dominated the world's oceans for hundreds of years, is obviously not comparable to the German Navy, which has only developed for more than 30 years. Of course, the decisive factor in naval battles, in addition to their respective strength, also depends on luck! If either side is lucky, it may be able to completely change the outcome of the naval battle.

"Both the Admiralty and the General Staff should focus on the decisive naval battle between Britain and Germany. This will have a great impact on the development of the Great War! Wang Yuze advised.
