No matter what Herbert thinks, or even feels that China has cast some kind of magic, it can't change the fact that China's submarines do have incomparably strong combat effectiveness, and the previous battle reports are true and reliable, plus today's sinking, in just 2 days, China's submarine force has achieved remarkable results, which will deal a heavy blow to the Allied forces, just yesterday's arms fleet, will cause problems with the supply of the Allied countries in Bordeaux, not to mention the merchant ships that are now frantically attacking, As long as the merchant ships of the Entente countries were controlled to a certain extent, even if the North Atlantic route was not blocked, it would be very beneficial to Germany.

At the end of 1915, because of China's accession, Germany obtained a lot of things that China had kept secret before, especially strategic artillery and various individual equipment, Germany's army combat effectiveness had almost increased by more than 3 percent, and all elite troops were equipped with various sub-projects. It has doubled, and under the advantages of one another, Europe in 1916 will be the world of Germany again.

Herbert is still on the way back, the fleet led by Deng Jieqian, did not continue to fight, today is basically over, in order to encircle and suppress such an unprecedented huge fleet, he used the entire submarine force, although it is said that the largest escort fleet in history, but the results achieved are not much, sinking tens of thousands of tons of warships, but the merchant ships in the end only won 32, many of which are less than 10,000 tons, The total tonnage is only 242,000 tons, which is not a little worse than the sinking figure of 600,000 tons on the first day, but the sense of accomplishment is greater, which can be seen from the excitement of every captain.

Since the advent of submarines, submarines have not been the mainstream of the navy, and in many cases, submarines are seen as villains hiding in the shadows to attack secretly, and can only attack while the other side is unprepared.

But now, the Qin-class submarine, with its real power, has proved that even if it fights the battleship head-on, the submarine has combat strength, which is enough to make the officers of the submarine worthy of their choice of path.

Deng Jieqian's subordinates, slowly retracted, and spent the evening resting, waiting for tomorrow's battle, the waves set off by submarines, has begun to gradually spread, this event recorded in the history of the First World War, for a long time, was considered Germany's retaliation for the actions of the Entente, until much later, when Germany declassified the archives and declassified, it was discovered that it was the hands and feet of the Chinese, when Britain, France and the United States did not even protest, because China had grown into an object that they could not match.

From this day on, Deng Jie's cadres showed great strength, the entire North Atlantic route was boiling again, the destructive power of 21 Chinese submarines is far more powerful than the sea wolves that have been won before, not only the attack power is strong, the 3,000-ton ocean-going submarine, his sustained combat ability, is not that the submarine can be compared with the United States, and the submarine can fight two wars at most, so he has to return, unless it is a long-term lurk, otherwise, after one or two attacks, he has to return, which is not efficient. However, Chinese submarines, on the premise of firing 16 torpedoes at one time, can also carry out three large-scale wars, not to mention that most of the time, two or three torpedoes will solve the problem, and the reserve ammunition of Qin-class submarines is as high as 64 rounds.

The entire North Atlantic, is simply boiling, the first two days of operation, the Chinese fleet completed the sinking of 840,000 tons, eliminated dozens of escort ships, more than 7,000 Allied naval soldiers sank into the sea, especially this time, the two Minotaur patrols, although in the current sequence of the British Navy, not the top kind, but also among the capital ships, 15,000 tons of giant ships, each one, at least 1,000 people, more than 2,000 rigorously trained, elite navy sunk into the sea, the blow to Britain can be imagined.

The most important thing is that the loss of merchant ships, two days before and after, lost more than 800,000 tons of merchant ships, although the intensity of the attack on the merchant ships is not large, most of the crew can still jump back, but whether it is a reconnaissance plane or a submarine, they have not collected the prisoners, waiting for them, I am afraid it is not a good ending.

For the Entente, the blow of merchant ships is greater than that of warships, after all, the patrol is not the capital ship, when the navy looks at the capital ship, the patrol sinks, but the merchant ship can not make up for it, the war has reached this extent, the duel between the two sides is all-round, the price of merchant ships has increased by 2 times compared with before the war, in this case, a large number of merchant ships, not only occupy more funds, but also not easy to supply, it is easy to rely on sonar to suppress German submarines, and the cumulative number of merchant ships can no longer grow, It's a blessing to be able to get through this hurdle.

The good days for Deng Jieqian came to an end on the third day, and after the third day still produced 200,000 sinking figures, the numbers began to rise sporadically, and in the next four days, an average of only 100,000 tons of sinking numbers were generated.

In the entire North Atlantic, close to the British side, there are not many ships, even with reconnaissance planes, it is difficult to find that the Entente has a total of more than 10 million tons of merchant ships, aside from half of the American and British ports, except for the merchant ships that are doing loading and unloading operations, less than half of them are sailing, most of them are still on the side of the United States, a small number of them have been sunk on the premise of this side, and the rest may only be more than 1 million tons. Others encountered merchant ships that had easily escaped their lives, and they chose to leave on the premise that they knew that their future was worrying

The sinking volume of 1.5 million tons in 7 days, the attack power of Chinese submarines, made Germany look sideways, and the most important thing is, how did China avoid sonar? This method must be obtained by Germany, which is very important for Germany, although the arrival of 31 submarines has given Germany a great help, but things are not in their own hands, and there is no bottom in their hearts.

After Herbert went back and recounted in detail what he had seen, the entire German Admiralty was boiling, it turned out that the previous results of the battle were not that the Chinese side had lied about the military situation, that was real, and could pass all kinds of tests, although the eyewitness was only Herbert alone, but according to Herbert's previous performance, coupled with the consistent good cooperative relationship with China, China did not need to lie to him.

Although there is no specific data on this type of submarine, the huge number of sunks in two days, especially today, 31 submarines, facing 18 warships, 16 of which are light cruisers that are useful for submarines, is enough to prove the strength of this submarine.

The Admiralty has its own ship-building plan, especially at the end of the year, under the premise that there is still a ship-building plan in the new year, it directly submitted a purchase agreement to China through the Ministry of Foreign Affairs, when China sent the Qin-class to the North Atlantic, it thought that Germany would definitely be blushing at the Qin-class under the premise that the submarine force had been hit by a huge blow, and in order to ensure Germany's deterrence in Europe, the Chinese government, under the promotion of Yang Yuanzhao, has begun to prepare for the export of the Qin-class, not only to determine the production line, but also to vacate the dock, Waiting for Germany's request, sure enough, in only 2 days, the Qin class won the order with the results.

Let's not talk about how much to order, first of all, China will give them some more important parameters of the Qin class, and they also get a set of parameters from the Chinese side, which is about the indicators of the Qin-class ocean-going submarines, with a standard displacement of 3000 tons, a full load displacement of 3600 tons, with 8 torpedo tubes, the first six and the last two, and the speed of rapid travel under water can reach 16.5 knots, even at the fastest time, the number of noise decibels caused by submarines does not exceed 110.

Germany's professional, not stupid, they have obtained the real thing of sonar, with the help of China, the basic parameters and working principles are known, this is a kind of amplification of sound, through amplification of sound, find the submarine hidden underwater, but it is easy to say, but everything has a limit, according to the average calculation, the basic decibel under the water is 90 decibels, that is, if the sound of the submarine is reduced to about 90 decibels, a sound is the sonar of the main detection method, It won't do anything, the ocean will become a black hole, hiding any sound, and it won't be detected at all unless it's a visual inspection or something.

In this sense, to avoid sonar, you must reduce the sound, it is easy to say, the Germans also proposed such a solution before, but the biggest sound under the water lies in the propeller and the power crew, these two aspects are two difficulties, the internal power unit, maybe you can use the material to absorb the sound, so that it is difficult for him to transmit the sound outside, but the outside, the propeller, it is impossible to put it inside, the submarine wants to move, you must use the propeller, otherwise, it is the same as the current waves, When the Allied fleet was discovered, the first thing was to shut down, hovering outside, just like that, if the shutdown was not timely, the submarine was not in a stationary state, the submarine followed the water, the propeller followed the water, and the same sound would be made, and this sound could not be avoided.

The German side has thought of a lot of methods, at most the decibel from more than 220, reduced to about 180, such a reduction is still far away, but China has guaranteed to tell the 110 decibel under the march, just this, you can avoid sonar, this is theoretically very simple, but how to do it, countless German submarine experts, after seeing the parameters, put forward their own questions.
