Deng Jieqian sighed slightly, it is indeed the strength of the whole of China, although it is said that the general framework is similar to before, but in terms of strength, it has been in his expectation, and it has been raised a notch, mainly the improvement of the torpedo, the electric torpedo, which can reach the speed and range of the aerodynamic torpedo, but this point, the concealment of the torpedo is extremely strong, and the power is also great.

The submarine itself is a concealed weapon, nothing is more important than concealment, torpedo attack, not only will expose the position, but also easy to be dodged, whether it is a merchant ship, or a warship, especially the latter, there are special lookout personnel to prevent sneak attack, but the electric torpedo, after the modification of China's fluidics, the formation of a smaller waterline, even in the daytime, in the area of poor vision, is not easy to be found, at night, it is a sharp weapon for sneak attack, with this, the submarine has the ability to attack warships.

Although as far as the submarine is concerned, the previous submarine also has the ability to attack warships, but that is basically equivalent to suicide, any surface ship, his speed, is faster than the submarine, once the submarine attacks, not to mention whether the torpedo can hit, his own safety can not be protected, electric torpedoes do not have this loophole, as long as it enters the night, the visibility on the surface of the water is reduced, after the submarine launches the torpedo, no one can determine where the submarine is, which has the possibility of confrontation with the warship, Just this point satisfies Deng Jieqian.

To this extent, the Qin-class basically met Deng Jieqian's requirements, attacking any merchant ship, breaking diplomatic relations or something, there was no stimulation to confront warships head-on, what was better than a small ship of one or two thousand tons. For battleships close to 20 thousand, or even more. Both have a direct threat to come stronger and more crossed, and this submarine satisfies him.

But. Continue to watch, the surprise continues, because of the enlargement of the hull, from the original prototype ship of 2500 tons, enlarged to 3700 tons, an increase of 1200 tons of displacement, so that the hull can be equipped with more torpedo tubes, front 6 rear 2, eight torpedo tubes. In battle, it can be fired in one go, and the most important thing is that it is double-shot, that is, after the first torpedo is fired, the second torpedo can be launched after 30 seconds to form the maximum density of the attack, for merchant ships and the like. Nothing, but if it is aimed at a battleship, the 12 torpedoes fired in a fan shape can almost envelop a fairly large sea area. The possibility of escape is minimized, although it takes at least 40 minutes to reload the torpedo after such a launch. But all the submarine needs is a blow, and he is not a battleship. It's impossible to fight against a battleship for a long time, that's not bravery. That's looking for death.

The huge tonnage not only accommodates more torpedo tubes, but most importantly, the number of spare bombs, 64 spare bombs, is enough to support the long-term combat of submarines. Such a submarine, theoretically, can hit 12 torpedoes from the front at one time, with the powerful power of the flying torpedo, for ordinary destroyers and cruisers, as long as it rubs a little bit, there is a huge threat, for the capital ship of more than 10,000 tons, as long as it hits the vital parts, there is a huge threat, especially the flying fish has armor-piercing performance, which is not possessed by any other torpedo, accurate calculation, impact and time under the dual control, can achieve a more reliable penetration after the explosion, As long as the thickness of the underwater armor is less than 80 mm of homogeneous steel plates, the Exocet can easily pass through with speed and armor-piercing performance, and then enter the internal explosion, which is enough to inflict heavy damage on a capital ship.

Deng Jieqian sensitively felt the power of this submarine, and he knew very well that just by virtue of this torpedo, the Qin-class would be able to cross the entire ocean, and even the cutting-edge dreadnoughts could become his merits and crown him.

In fact, this Exocet, in the future, has more than 30 different modifications, from destroyers, submarines, to torpedo machines, different uses, all have a professional focus, derived from a large family, but also become one of China's enemies, one of the feared weapons.

In addition to the torpedo, the new submarine, more to improve the foundation, such as the internal structure, from the previous prototype of the adjustment, China's new discoveries on fluid mechanics, almost all used here, the adjustment of the structure of the hull, so that he is more suitable for the fluid mechanics aspect, so that the same speed, it will receive less resistance, on the other hand, the noise of the battleship is more reduced.

In the North Atlantic, many German submarines were sunk because on the one hand, the plan was not very thorough, wasting a lot of space, but the attack was not developed to the extreme, on the other hand, the decibels of the submarine were too high, as long as it was an entry-level sonar, the noise of the submarine could be heard, and after a large number of depth charges were dropped, the submarine would be finished.

On the shell of the Qin-class submarine, the Northwest pioneered the use of suction tiles, to a certain extent, it can absorb the noise of the entire submarine, so that the decibels of the submarine are close to the 90 decibels of the ocean background, and the maximum noise is the propeller, and because of the progress of auxiliary settings and fluids, when cutting the seawater to produce thrust, it will be more gentle, whether it is high-speed forward or steering, it will not produce much decibels, at most 110 decibels, such decibels are quite obvious in the background of the ocean. But it is no longer something that can be heard by the primary sonar, so it can become more concealed.

With a little control, Deng Jieqian understood that this submarine, in terms of its power, must be twice as powerful as other submarines, if the strategy of sharks is adopted, a battleship is introduced into the encirclement of the submarine, I am afraid that this battleship will also have a hard time.

After receiving the submarine, Deng Jieqian also received his mission, to go to the North Atlantic, help Germany, cut off the North Atlantic route, and attack the power of the Entente under water.

Only then did Deng Jieqian understand that nothing was as simple as he had thought, and that this matter should have something to do with the boiling evacuation incident that was being publicized at present, and that before all the overseas Chinese were withdrawn, the naval attack could not go directly, and the submarine would not have much scruples. As long as you don't get caught by the other party, or sink it. Find the evidence, who knows whether it is Germany or China under the water.

And even if it is caught. So what, the Entente has already declared war on China, and the two sides are in a state of war, in which case any means can be used.

The reason why the top brass of the Navy chose Deng Jieqian was also a very helpless choice, because there was not enough time.

Since it is against the Entente, it will definitely be against the opposing warship. The submarines before the Qin class were much more powerful than the German submarines, but they were not able to confront the warships head-on, and the submarines might be able to avoid the sonar search, but the torpedoes could not be hidden, and if they really confronted the other side head-on, they would suffer a great loss.

China sent troops to the North Atlantic to fight. It was for profit, not for sacrifice, and China, unlike Germany, did not have enough naval members. If more than a hundred submarines are really lost, the blow to China will be almost devastating.

So. At this critical moment, the Qin class was officially finalized and put into production. became the ultimate goal, and personnel selection was on top. With Deng Jieqian's experimental troops as the mainstay, they are the ones who can put the Qin-class into play as quickly as possible, and then assist the main forces of some other submarine forces, and they can form a huge submarine force.

After the first Qin-class was sent to Jiangyin, the other ships were also put into use one after another, but the time was a little behind, and Deng Jieqian's task was also quite heavy, they only had less than 10 days to adapt, and then, a larger-scale sea trial needed to be at sea, on the way to the North Atlantic, such a time, full of calculations, was only about 40 days.

Deng Jieqian is also one of the few people who have participated in actual battles among the submarine forces, but in those actual battles, submarines are always in the position of ambushes, they are hiding behind the capital ships, pumping cold, and fighting ambushes.

Now that he is alone and goes to Europe, there is definitely a chance to fight with warships, or even capital ships, if he really sinks a capital ship in a frontal battle, then the Qin-class will be really famous, and Deng Jieqian is also full of expectations.

10 days of time in a blink of an eye, among China's many docks, 31 Qin-class ships have also been launched one after another, weapons and equipment are the same, and the personnel, after more than ten days of intensive training, the fleet with the experimental fleet as the core, is basically in place, close to 2,300 sailors, basically reached the largest size of the fleet, and the fleet has also moved to Hainan, in the secret base in Hainan, ready to set off at any time.

The surface speed of the submarine reached more than 21 knots, even if it was a relatively economical cruising speed of 14 knots, and a long range of more than 7,000 nautical miles was enough to support the overseas operations of the Qin class, as long as China's supply ships appeared in key places, at most 40 days, this powerful force would arrive in Europe.

Finally here, standing on the deck of the ship, although the submarine has 16.5 knots, such an amazing underwater speed, but in the ocean voyage, no one will be brain-dead enough to sail underwater, in the era of no nuclear power, or in the era of successful development of teardrop-shaped submarines, the water is always much faster than the underwater, the Qin class in the fluid design, cancel the guns above the deck, but the simple flat deck and some handrails are still available, these do not affect the underwater navigation, and can even be recovered in the underwater navigation.

The submarine is a relatively confined space, staying underwater for a long time, for anyone, is a relatively depressing thing, even if it is Deng Jieqian, who has been in the submarine force for a long time, if he has the opportunity, he will still come out to breathe.

At this time, the troops had already passed through the Strait of Malacca and entered the rough Indian Ocean, and the unique ability of the submarine made the submarine's survivability in the high sea far above that of ordinary ships.

The wind and waves under the water are always much smaller than those on the water, as long as the surface water surface is avoided, even the impact of the storm on the submarine is very small, as for the ordinary wind and waves, it is even more fine, the fully sealed submarine is not afraid of irrigation at all, that is, it can ignore these wind and waves.

It was already very late, Deng Jieqian looked at the fleet behind him with a little pride, at most 25 days, they will arrive in the waters of the North Atlantic, 31 submarines, will definitely shock the whole world.

At the same time as the submarine force departed, the Chinese ambassador to Germany also urgently met with the German foreign minister to inform them of the news that the Chinese submarine had come to support.

To be honest, Germany is also very surprised, the United States-led Entente declared war on China, for Germany, is a shot in the arm, but because of the relationship between overseas Chinese, in Germany's view, China has no ability to intervene in the war for the time being, more than 2 years of war coming, Germany is very clear, China is not ready for war, from the era of peace to wartime is a very long process, the United States has long had the intention of entering the war, but it took a year of preparation time, from the era of peace, into the wartime economy, this joined the European war, In this way, they also lost a lot in the early days.

According to the German government's estimates, even if China was the fastest, it needed to be able to participate in the war by the middle of 1916, to a certain extent, to support the actions of the Allies, and this was not until 1916, when China's support came, albeit only 31 submarines.

German submarines because of the appearance of sonar, suffered a big loss, has lost more than 100 submarines one after another, this is an unbearable weight, personnel losses are still secondary, the key is the strategic loss, Germany will not be able to threaten the Allied North Atlantic transport lines, in this sense in 1916 the Allied forces will be strengthened, Germany will face greater pressure, at this time, Germany is in need of Chinese submarines.

As an ally, especially such an important and powerful ally as China, the Admiralty still made a kind reminder that the ships of the Entente countries are equipped with sonar, which is a sharp weapon against submarines, and if the Chinese side does not have weapons to deal with him, it is better not to go out.

The implicit meaning of the Germans, the ambassador knew very well, in fact, when he received the telegram from China, he also warned through the secret channel, but the country was very clear about the American sonar, and officially told him that the sonar was fine, but he did not tell him how to deal with it, so he could only tell the Germans in a high profile that they had a way to deal with it.

Germany's purpose is only to fulfill the duties of an ally, and it did not insist, now Germany does need the support of submarines, and the obligation to remind has been fulfilled, since the allies insist on coming, then come, more than 31 submarines, the role of the North Atlantic is also quite large, maybe it threatens the communication lines of the Entente.
