Mr. Jiang became more and more satisfied with Feng Quan sitting in front of him. Not only did he turn the tide many times during the September 18th Incident, the January 28th Incident, the Rehe War, and the Great Wall War, but he also donated huge amounts of money to the Party and the State many times.

The suggestion Feng Quan just now gave to the Chinese Navy was solved with a quick solution to the big thought that had been lingering in Chiang Gong's mind.

Anyone with a discerning eye can see that the gap between the Chinese Navy and the island navy is not the same as the same level. As a far-sighted strategist, Chiang Gong naturally knew it well.

It is clear that it will not help solve this problem. Just maintaining a battleship or aircraft carrier will cost almost all the expenses of the Party and the State Navy, and there is even a rhythm that is not enough. Chiang Kai-shek's head is very

big.

Now this dilemma is actually solved. When Feng Quan talks about mines and submarines, Mr. Jiang's eyes were always bright, and he even laughed rarely.

Just now, the newlyweds and old couples in the base also participated. The first man in China, Jiang Gong even brought the first lady to congratulate him. Feng Quan was also very excited.

.

What made Feng Quan most excited was that after he traveled through time, as one of the countless time traveling troops, he finally did not discredit them and did not fall behind.

With his own participation, he finally made some contributions to the many disasters and difficulties in China.

Now that Duke Chiang has accepted his own suggestions, the future full-scale war of resistance will definitely no longer be as bumpy or as in history as in history.

"Principal, when it comes to submarines, we must talk about Germany. There are so many countries around the world that they have the most experience in using submarines!"

Germany has always been a country that Chiang Kai-shek strongly advocated. Chiang Kai-shek is very energetic, "Oh? The situation of the gods? Tell me about it!"

“Several years ago, on December 14, 1906, the first submarine of the German Imperial Navy was officially put into service at the Port of Kiel.

It was a haze day, and 12 German sailors who were trembling with cold, drove their 42-meter-long new thing on a journey with uncertain future.

For the history of naval warfare and even world history, this means that a new century of military and political adventure that "if you fail, you will be successful" has officially begun.

Germany did not start early in developing a submarine. This submarine was the first submarine built by Krupp in 1905, called U-boat.

By the time World War I broke out, Germany had built 23 submarines and 17 submarines under construction.

On September 22, 1914, in the North Sea, the captain of the submarine Vedigen sank three British Royal Navy light cruisers within 25 minutes, creating a myth of naval warfare history and making him the mind of the Germans since the war began.

The first national hero.

In fact, the reason why the German submarines achieved great success in this battle was that after the Abukier was hit, Hog and Cresey not only did not escape, but instead stopped to rescue the officers and soldiers who fell into the water."

"Shenma? Sink 3 warships in succession within 25 minutes!"

Mr. Jiang was shocked. In his mind, although the armor of the light cruiser was not as good as that of the ship's strong and powerful battleships, it was still hard to imagine sinking three ships in a row within 25 minutes.

But soon, Feng Quan told Chiang about a more glorious battle history of the German Navy.

"The most brilliant result of the German Navy in World War I appeared in the second year, the famous British Lucitania incident.

In May 1915, the ship was sunk by the German submarine U- near the coast of Ireland, killing 1,198 people, of which one (one was a citizen of the then neutral United States.

The luxury passenger ship flew the flag of the neutral United States and received an order to transport a large number of war supplies and soldiers across the Atlantic Ocean. At that time, the ship was loaded with 105,000 tons of explosives and arms. The German Navy only launched two torpedoes, which triggered a large number of large numbers of war materials and soldiers.

explode.

After tasting the sweetness, the Lucitania incident became the beginning of Germany's comprehensive unrestricted submarine warfare and was also the inducement for the United States to directly participate in World War I."

Mr. Jiang nodded and agreed, "Mr. Zi. It seems that you were staying in the United States before. As expected, you know more detailed data about these things than we do. "

Seeing Feng Quan's rhythm of restlessness due to smoking addiction, Mr. Jiang smiled and said, "Hehe, my son, would you please give me a cigarette?"

"Shenma?"

Feng Quan said he was a little stunned. In his impression, Mr. Jiang seemed to have no cigarettes and alcohol. This time he asked for cigarettes for himself. It must be because he had the method to develop the navy.

Lilily gave Mr. Jiang a good cigarette, and Feng Quan was about to speak, "Cough cough...", and Mr. Jiang, who was almost insulated from the tobacco and alcohol, could no longer hold it.

"Haha, keep going!"

"In early 1906, the Germans built the U-type submarine powered by diesel engines for the first time.

On September 5, 1914, the German submarine U21 sank the British ship "The Pushman" with a torpedo, and 250 British soldiers were buried under the sea.

On September 22, 1914, the German U9 submarine sank three 100-ton British armored cruisers in a very short time, and 1,500 people were killed on the ship.

After implementing the unlimited strategy, until the end of 1915, German submarines sank more than 600 merchant ships from allied countries;

In 1916 and 1917, the total number of merchant ships sunk by major Allied countries, Britain, France, Russia and the United States, which later participated in the war, reached 1,100 and 2,600 respectively.

The German Navy's biggest contribution was a U35 submarine. Its owned itself, sank 226 ships, totaling more than 500,000 tons!

During the entire World War I, the total number of merchant ships sunk by German submarines reached 5,906, with a total tonnage of more than 130,000 tons!

According to statistics, there were 192 combat ships that were sunk with submarines in the entire First World War, including 23 cruisers, 39 destroyers, 30 submarines, and even 12 battleships!!”

When he stretched his neck and heard Feng Quan say this, Jiang Gong's surprise could not be described as dumbfounded. His mouth was wide open and he could even pretend to be an apple.

"Since you are so clear about these data, can you tell me how many submarines of the Allies and the Allies add up?"

"puff......"

Feng Quan, who was a little nervous, spat a puff of the smoke ring and then said.

"In World War I, each participating country built more than 640 submarines, of which 4 were built by Germany alone (especially the U-type submarines were released at sea with their excellent underwater maneuverability and combat capabilities.

The limelight.”

Mr. Chiang nodded constantly, his mind was spinning rapidly, constantly looking forward to the great achievements of the Chinese Navy's submarine force in the full-scale war of resistance.

"Zigong, this submarine should have many shortcomings, right?"

Feng Quan considered it and then told the shortcomings of the submarine one by one to Mr. Jiang, who did not know much about the submarine.

1. The submarine has poor self-defense capabilities and lacks effective air observation methods and air defense weapons;

2. Underwater communication is a bit difficult and it is not easy to achieve two-way, timely and long-distance communication;

3. The detection equipment has a close distance, limited observation range, and is easily affected by the environment, so it is difficult to grasp the enemy's situation;

4. The underwater speed is low, and the endurance is extremely limited when sailing underwater at high speed;

5. The submarine must be in a snorkel navigation state when charging, which is easy to be exposed;

6. The underwater self-sustaining power is poor, and the maximum self-sustaining time is generally about 45 days;

7. Submarines are not easy to achieve coordinated combat, and two submarines on their own in the same sea area are prone to collision.

"Overall, the disadvantage of submarines is that their communication and detection methods are limited, and the sonar system is basically unfunctional during high-speed navigation, with high noise levels, and is easily detected by the enemy.

It is because of these shortcomings of submarines that during World War I, Germany built a total of 4 (submarines of three levels, but 2 of them were missing in battle, and only 178 ships directly attacked the Allied ships.

”

Feng Quan did not hide anything, and told Chiang Kai-shek the advantages and disadvantages of the submarine one by one.

Although submarines are cheaper than surface warships and are very suitable for sneak attacks, they actually have so many shortcomings.

After learning about this, Mr. Jiang was a little excited and his mood was a little low. Feng Quan quickly continued to instill some confidence in him.

"Although the submarine is also at risk of being sunk, some losses can be almost neglected compared to the outstanding results achieved.

It is precisely because of the mass production of submarines that this has become the only means for German armed forces to weaken the strong maritime hegemony of the Allies.

After suffering such a huge loss, the Treaty of Versailles specifically stipulated that Germany could not own submarines in the future."

"Um!?"

Mr. Chiang became interested again, "You are familiar with some foreign intelligence, what are you doing now in Germany?"

"Haha, like heavy artillery in aircraft, although the Allies have many restrictions on Germany, Germany still secretly develops these in countries such as Sweden.

In particular, Hitler, since he came to power, has made up his mind to fight against the old naval power Britain, and decided to vigorously develop the navy, mainly to build submarines and large surface combat ships.

Navy Colonel Denitz accepted this mission and decided to build large submarines for ocean-going operations. Due to restrictions on the Treaty of Versailles, the development of submarines requires secret operation, and secret design work has been carried out in the Netherlands, Finland and other countries."

"Yeah!" Mr. Jiang nodded, "It seems that the advantages of submarines are quite outstanding. Our China also needs to develop cheap and affordable submarines! Mr. Mr., you can hurry up and buy larger ones or smaller ones in China.
Chapter completed!
