The entire German Admiralty is looking forward to the moment of the return of the Qin class, at this moment, Deng Jieqian led the submarines, still persisting in the North Atlantic, from the third day, the difficulty of their attack on merchant ships has increased geometrically, sometimes, the reconnaissance planes spent a morning, may not be able to find the target of the attack, but they are still persistent, for the war, only by persevering, will usher in the final victory.

After a week or so of high-intensity fighting, the entire Deng Jieqian department reached the limit, and the vast majority of submarines had already sent out the last torpedoes, even the rear launch tubes, and put them in front to launch, they didn't even have torpedoes for self-protection, and the submarines had no torpedoes, just like guns without bullets, it was just an ornament, and after knowing that most submarines were like this, Deng Jieqian finally decided to return.

Seven days was the most glorious time for Deng Jie's cadres, and they achieved 1.5 million tons of merchant ships and nearly 120,000 tons of warships, and the total displacement was only about 60,000 tons of submarines.

In 7 days, the Entente direction also found something, but did not deal with it, but the British home fleet, for the patrol of the North Sea is intensifying, unfortunately, this patrol does not have much impact on the submarine, the submarine in the return, more stable, sometimes will reduce the speed, It is not the limit speed of 16.5 knots, the noise decibel is further reduced, and the sonar system of the Entente is not familiar with the Qin class, which is also the root cause of such a huge role played by Deng Jie's cadres during this time, even if Britain is aware of it and sends destroyers and light patrol troops, there is no trace of Deng Jie's cadres.

31 submarines, divided into different directions, returned to Germany, although it is said that China's secret supply ships can also supply these submarines, but in the current situation, there are not many results, rather than floating on the sea in vain, it is better to return to Germany, on the one hand, according to the requirements of the German side, to show Germany the role of the Qin class, on the other hand, they need to come back to rest, refuel, supply, and rest by the way.

In the Baltic Sea, Scheer with the high seas fleet is fighting against the Allied fleet, saying that it is a confrontation, in fact, it is across the Baltic Sea, the two sides have clashed several times in the past time, although Scheer occupies a little cheap, but it is not big, Britain after realizing the strength of the fantasy class, it will no longer risk a duel with the Scheer fleet with the fantasy class as the core, but maintain a certain distance, in short, make Scheer very uncomfortable, but can not grasp the distance, in this distance, the two sides can only maintain each other.

It was precisely because of the cover of the main fleet that the destroyer fleet and the light cruiser fleet were able to search for Deng Jieqian's troops with all their might, but unfortunately the accuracy of their sonar measurements could not be reached, even if the submarine passed under their noses, they would not find it, let alone catch it.

As a matter of fact, Deng Jie's cadres entered the Baltic Sea under the noses of the search fleet and the home fleet, and after entering, they sent a telegram to Scheer, and Scheer breathed a sigh of relief, and at the same time, his vigilance against Deng Jie's cadres was raised to a higher level.

After Germany was attacked by sonar, China also exported some primary sonar to Germany, which were installed on the light cruisers and destroyers of the High Seas Fleet.

But now, this powerful sonar has failed in front of the Qin level, this is not a drill, but a real fight, and it was not until Deng Jieqian took the initiative to show his traces that they found out where Deng Jieqian's fleet was.

The sonar currently used in Germany, although it is not the latest sonar, is similar to the United States in terms of sonar technology, but in terms of reliability in semiconductor materials and batteries, it is much higher than that of the United States.

Knowing the problem of the sound of the submarine, they also know that solving the sound is the best way to deal with sonar, but how to solve it, it is easy to say, if the submarine does not move, it will not make a lot of sound, but the submarine is a combat weapon, it is impossible to move forever, once it moves, the submarine will be easy to find, this is completely an unsolvable problem, now China has not only done it, but also used the actual combat, is it really so easy?

The submarine persuaded Scheer with actual combat, but the exercises that should be carried out are also indispensable, and China has proved the powerful attack power of their submarines with indisputable facts, but the Admiralty and many scientists still do not believe it, even if there is Scheer next to prove it, this is the exercise.

That is, it is very simple, the Chinese submarine has been quite tired due to continuous operations, leaving only a part of the necessary personnel, and the rest is provided by the German side, even before, under the premise of huge losses, Germany's naval background is much higher than China's, and soon found a group of strong personnel, they only did a simple test, 10 destroyers equipped with sonar patrol, submarine assault.

Sure enough, the sonar couldn't hear clearly, in fact, I heard a little bit of sound, which was on the premise of knowing that a submarine was coming, and the previous sound was slightly different, if you weren't careful, it was easy to miss it, which was enough to show his concealment.

The Germans are rigorous, they are rigid, they believe that seeing is believing, even if they hear a little sound, as officers, they think that during the long escort and voyage, it is almost impossible to find the trace of the submarine from the middle, similar noise, even from Hamburg, Germany to the mouth of the Baltic Sea, will be heard dozens of times, hundreds of times, sometimes, a slightly larger school of fish, or a large fish or the like, will make a certain sound, each of which has to react, The convoy doesn't have to do anything else.

Next, of course, the submarine launches the torpedo, which is one of the concentrated manifestations of the submarine's combat effectiveness, which proves everything with the indisputable performance of the flying torpedo, when Germany was still using the white-headed torpedo, the maximum speed of this torpedo is only 35 knots, the strongest improved version, it is only 40 knots, but the flying torpedo has increased by 25 knots, the most important thing is that the traces, the reason why the torpedo is not effective, in the large-scale battle line duel, it has no longer become the main tactic, that is, the relationship between the traces, The reason why submarines are not high in the navy is mostly because of this, submarines cannot follow the battle line duel.

This point, even the Qin class can't solve it, but one thing is certain, that is, the Qin class has the basic ability to fight with the battle line, 16.5 knots of underwater speed 10 hours range, these two are combined together, it forms the strength of the Qin class, take the battle of Scheer's return as an example, the high seas fleet because of the British blockage, can not enter the North Sea, help Scheer, Scheer only relies on his own strength, and a little luck, this is the return, but any blockade, can not block the submarine, The submarine can easily break the defense, under water, as long as it is a target that the sonar can not explore, it can easily break through the defense line, even in the duel of battleships, it is quite long, 1 hour, a morning, or even a day, in this way, even if the speed of the submarine is a little slower, it is enough to catch up with the main fleet.

In the chaotic, when the battle line has been formed, an unknown number of torpedoes, drilled into the bottom of the sea, when they carry out a free attack, what kind of attack power will be, 6 torpedoes, the successful Minotaur sent to the bottom of the sea, then the dreadnoughts and super dreadnoughts that are stronger than the Minotaur, in the face of torpedoes, they can't be better, according to the naval officers know, even Orion, even high-speed battleships like the Queen Elizabeth class, they have thicker armor, but below the waterline, They are still weak, after all, no one will put the precious tonnage below the waterline.

Flying torpedoes, Qin-class submarines, have been on the German Admiralty's purchase list, but after looking at the price, they are also a little painful, the sales price of the flying torpedo is almost 5 times higher than the ordinary white-headed torpedo, which is a relatively conventional weapon such as a torpedo, this number is definitely not small, you know, the purchase of torpedoes, not only submarines, but also destroyers, and even youth training, the number of purchases, will exceed 50,000, 5 times the price, occupy a considerable degree of foreign exchange.

But after thinking about it, the Admiralty still decided to procure, the Exocet torpedo can be used as a special combat weapon, with the current strength, hundreds, less than a thousand, just the Entente 1.5 million tons of merchant ships, more than 120,000 tons of warships, sent into the depths of the sea, from a little from the top, you can see that this thing is worth its money, excellent performance, can be able to hit the enemy.

Compared with the non-flying torpedo, the cost of the Qin class is higher, from the tonnage, he is almost twice as high as the largest German submarine, but the price, almost ten times, according to a 1,500-ton submarine, the price of about 400,000 US dollars, the price of the Qin class is as high as 4 million, almost one-seventh of the price of a battleship,

But this thing is the same value, faster speed, more powerful weapon, and completely subversive design, which allows the Qin-class to freely gallop underwater, which is enough to make Germany tempted and invest a lot of money to buy. (To be continued.) )
