The entire German Navy is looking forward to the moment when the Qin-class returns. At this moment, Deng Jiegan led the submarines and still insisted on fighting in the North Atlantic. From the third day, the difficulty of their attack on merchant ships has increased significantly. Sometimes, the reconnaissance aircraft may not find the target of the attack after spending a morning, but they are still persisting. For war, only by persevering can they usher in the final victory.

After about a week of high-intensity combat, the entire Deng Jie cadres reached the limit. Most submarines had already sent out the final torpedoes, and even the rear-range launcher tubes were taken out and fired in front. They even had their own torpedoes. The submarines had no torpedoes, just like guns and bullets, and they were just a decoration. After knowing that most submarines were like this, Deng Jiegan finally decided to return.

7 days was the most brilliant time for cadres Deng Jie. He achieved 1.5 million tons of merchant ship sinking numbers and nearly 120,000 tons of warship sinking numbers. The total displacement was only about 60,000 tons of submarines. It can be said that he achieved outstanding results, several times, or even dozens of times his tonnage.

In 7 days, the Allied Power also discovered something, but did not respond to it. It was just that the British local fleet was strengthening the patrol in the North Sea. Unfortunately, this patrol did not have much impact on the submarines. When the submarine returned, it was more stable and sometimes it would reduce the speed, not the limit speed of 16.5 knots, and the noise decibels were further reduced. The Allied Powered Power's sonar system was not familiar with the Qin-level. This was also the root cause of Deng Jie's role playing such a huge role during this period. Even if the United Kingdom noticed it, and sent destroyers and light patrol troops, no trace of Deng Jie's cadres was found.

The 31 submarines were divided into different directions and returned to Germany. Although China's secret supply ships could also supply these submarines, under the current situation, there were not many results. Instead of floating on the sea, it would be better to return to Germany. On the one hand, according to the requirements of Germany, they showed the role of the Qin-class to Germany. On the other hand, they needed to come back to rest, refuel, and rest with them.

At the mouth of the Baltic Sea, Scher led the high seas fleet to confront the Allied fleet, saying it was confrontation, but in fact it was a confrontation between the two sides in the past time. Although Scher had taken a little advantage, it was not big. After the British realized the power of the fantasy level, they no longer took the risk of confronting the Scher fleet with the fantasy level as the core, but maintained a certain distance. In short, Scher was very uncomfortable but unable to grasp the distance. In this distance, both sides could only maintain confrontation.

It is precisely because of the main fleet that the destroyer fleet and the light patrol fleet were able to search for all their strength in their cadres. Unfortunately, their sonar measurement accuracy was not up to date. Even if the submarine was passing by under their noses, they would not notice it, let alone catch the submarine.

In fact, under the noses of searching for the fleet and local fleet, Cadre Deng Jie entered the Baltic Sea. After entering, he sent a telegram to Scher. Scher was relieved and at the same time, his vigilance towards the cadres Deng Jie has reached a higher level.

After Germany was attacked by sonar, China also exported some primary sonar to Germany. These sonars were installed on light patrols and destroyers of the high seas fleet. In the past, they would do some measurements when submarines were operating, which was also accumulating experience. The Allies did not have any submarine strength that could be shown, but they were planning ahead. What if?

But now, this powerful sonar has failed in front of the Qin-level. This is not an exercise, but a real one. It was not until Deng Jiegan took the initiative to reveal his traces that they discovered where Deng Jiegan's fleet was.

Although the sonar currently used by Germany is not the latest sonar after all, its technical level is similar to that of the United States, its reliability in semiconductor materials and batteries is much higher than that of the United States. This sonar officially explains why German submarines were sunk in large quantities, and German submarines have nowhere to hide in front of the sonar.

Knowing the sound problem of submarines, they also know that solving the sound is the best way to deal with sonar, but how to solve it is easy to say. If the submarine does not move, it will not make many sounds. However, the submarine is a combat weapon and cannot be moved forever. Once it moves, the submarine will be easily discovered. This is a completely unsolvable problem. Now China has not only done it, but also used actual combat. Is it really that easy?

The submarine convinced Sher with actual combat, but the exercises that should be carried out are indispensable. China used indisputable facts to prove the powerful attack power of their submarines. However, the Navy and many scientists still didn't believe it. Even if Sher was proof next to her, this exercise was achieved.

It is very simple. Chinese submarines were already quite exhausted due to continuous combat, leaving only a part of the necessary personnel, and the rest were provided by Germany. Even before, under the premise of huge losses, Germany's naval foundation was much higher than China. Soon a group of powerful personnel were found. They just conducted a simple test, and 10 destroyers equipped with sonar were patrolling and submarine assaulted.

Sure enough, the sonar couldn't hear clearly, and in fact he heard a little sound. This was a little different from the previous sound, if he knew that a submarine was coming, and it was slightly different from the previous sound. If he was not careful, it would be easy to miss it. This is enough to show his concealment.

The Germans are rigorous and rigid, they believe that seeing is true. Even if they hear a little sound, as officers, they believe that it is almost impossible to find the traces of submarines in the middle during the long escort and voyage. Such noises can be heard dozens or hundreds of times even from Hamburg, Germany to the estuary of the Baltic Sea. Sometimes, slightly larger fish or big fish will make a certain sound. If each one has to react, the escort fleet will not have to do anything else.

Next, of course, the submarine launches torpedoes, which is one of the concentrated performances of the submarine's combat effectiveness. This undisputed performance proves everything. When Germany was still using white-headed torpedoes, the maximum speed of this torpedo was only 35 knots, and the strongest improved version was only 40 knots, but the flying torpedo increased by 25 knots. The most important thing is that the reason why the torpedo is not effective is that it no longer becomes the main tactic when the large battle line duel is that the submarine is not in the high sequence of the navy. It is mostly because of this. The submarine cannot follow the battle line duel.

Even the Qin class cannot solve this point, but one thing is certain, that is, the Qin class has the basic ability to fight along the battle line, with an underwater speed of 16.5 knots of 10-hour voyage. The combination of these two forms the power of the Qin class. Take the battle of Sher's return as an example. The high seas fleet was unable to enter the North Sea due to the British blockade. Sher. Sher returned only with his own strength and a little luck. However, no blockade could block the submarine. The submarine could easily break the defense. Underwater, as long as it was a target that sonar could not explore, it could easily break through the defense line. Even in the duel of battleships, it was quite long, 1 hour, one morning, or even a day. In this case, even if the submarine was a little slower, it was enough to catch up with the main fleet.

At the moment when the battle line was already formed, unknown torpedoes drilled into the seabed and launched a free attack. What kind of attack power would be? 6 torpedoes, if they succeeded, Minotao sent to the seabed. Then, the dreadnought and super dreadnoughts that were stronger than Minotao, faced with torpedoes, could they not be better. According to what the naval officers knew, even high-speed battleships such as Orion or even Queen Elizabeth-class, they had heavier armor, but below the waterline, they were still weak. After all, no one would put the precious tonnage at the waterline.

Flying Fish torpedoes and Qin-class submarines have been on the purchase list of the German Navy, but after looking at the price, they felt a little painful. The sales price of Flying Fish torpedoes is almost 5 times higher than that of ordinary white-headed torpedoes. This number is definitely not small for more conventional weapons such as torpedoes. You must know that the purchase of torpedoes is not only submarines, but also destroyers, and even youth training. The number of purchases will exceed 50,000, which accounts for a considerable amount of foreign exchange.

However, after considering it, the Navy decided to purchase it. Flying fish torpedoes can be used as special combat weapons. With the strength it has shown so far, hundreds, less than a thousand. Just send 1.5 million tons of merchant ships and more than 120,000 tons of warships from the Allied countries into the depths of the sea. From drinking a little, you can see that this thing is of great value and excellent performance, so that it can attack the enemy.

Compared with the non-flying fish torpedo, the Qin-class cost is even higher. In terms of tonnage, it is almost twice as high as the largest German submarine, but the price is almost ten times. According to a 1,500-ton submarine, the Qin-class price is as high as 4 million, which is almost one-seventh-century battleship.

But this thing is also worth the money, faster speed, more powerful weapons, and completely subversive design. These allow the Qin-level to freely gallop underwater. This is a weapon that is enough to make Germany excited and invest a lot of money to buy. (To be continued.)
