Recently, because of the loss of paratroopers, akado missed the service ceremony of the Navy's new equipment. However, the ceremony was held on time under the chairmanship of deputy commander of the Navy Randall and General Commander of submarine forces Donitz.

In a shipyard in Hamburg Port, Germany, 40 of the best submarine officers and men stood in four rows with their hands behind their backs, waiting for the military band on one side to play a solemn battle song. In fact, the new submarine is now parked in the closed special submarine dock. The military band and the current crew have not seen this new equipment, which is known to change the submarine's combat mode.

"General Donitz, can this new type of submarine really change the operation mode of submarine forces in the case of ocean warfare, as those designers boast?" With the sound of the military music, marshal Reidel leaned a little, leaned up to Donitz's ear and asked softly.

He was wearing a black admiral dress with double rows of gold buttons. He looked very energetic. After all, under his command, he was a powerful fleet that defeated the world's first navy. He could be said to be the most successful high-level naval commander since the birth of Germany. Although most of these achievements have nothing to do with him, after all, when he was the top commander of the Navy, the German Navy made terrible achievements that shocked the whole world.

It can be said that he has already stood at the peak of the whole Imperial Navy. The battleship named after him, marshal Reidel, is even the first battleship in the true sense since the new construction of the German Navy. It may also be the last battleship.

Donitz nodded. He was the top submarine commander who had seen the new submarine test. He even witnessed the whole process of the submarine from birth to development. Because of the improvement and development of material technology, this submarine is destined to become the representative of the highest science and technology in this era, and it is also destined to be forever engraved on the history of human weapon development because of its terrible performance.

"The new power is a terrible system that has been created, which allows submarines to navigate underwater for a long time." Donitz tried to explain the German Navy's super weapon to Reidel with less confidential data: "the birth of this submarine marks that the submarine weapon has evolved into a real submarine from today on."

"So much change? What is a real submarine? Wasn't it a real submarine before? " Randall stopped and became more confused. He looked at Donitz, waiting for a more popular and reasonable explanation.

After all, this weapon is enough to make him work out more terrible wolf tactics and more desperate strangulation system: "marshal, the weapon we used to drive was only a diving ship, but now this submarine is simply a submarine that can surface."

"What's the difference?" Randall still didn't understand the difference between the two, but he immediately realized something. Before Donitz could show off his new toy, he asked, "do you mean... The main sailing state of this submarine is underwater?"

"Yes, marshal." Donitz nodded triumphantly, with a proud expression on his face: "this submarine can dive far and far, and it can dive for a long time. Underwater speed... "

He lowered his voice, put it in his ear, and whispered a number: "more than 15 knots."

"Hiss!" Randall couldn't help taking a breath. The temperature in Hamburg military harbor in October was very low, so he took such a strong breath that his lungs were a little thin and irritated. He coughed violently: "cough! Cough! Cough

The military band is still playing, standing in the middle of the crowd. As the most unlucky and most brilliant submarine commander in the German Navy submarine formation, prien stands at attention, and suddenly sees marshal Reidel not far away coughing violently. I don't know what kind of stimulation he has suffered.

"Cough!" After coughing, Randall looked at Donitz with shocked eyes, and for a moment he was too scared to speak. As a commander of naval surface ships, he is familiar with the operational rules of fleet antisubmarine. Can he know what this speed means for surface ships.

In this era, the sonar installed by almost all surface ships is not accurate. We just roughly find the location of submarines, and then use the explosion radius of mines in the deep sea to make up for the embarrassment of insufficient attack accuracy. Now the speed of submarines has been increased by three times, This means that the approximate position of the submarine can no longer be used as the basis for the surface ship's attack. The moment you drop the deep-water bomb, the other side is out of the damage radius of the deep-water bomb.

The reason why most submarines in World War II are designed with sharp bow is that submarines need to travel on the water most of the time, so they should be designed as ship type as far as possible to reduce the driving resistance and improve the seaworthiness of submarines. However, this kind of design is obviously not prepared for underwater driving. In addition, the operating power of the battery under water is not flattering, so the underwater speed of World War II submarines was maintained at about 5 knots in most cases.

However, at the suggestion of akkado, the German developed fuel cell as a fashionable device in the white orchid laboratory as early as 1927. After ten years of technical reserve, this new submarine underwater power scheme finally reached the design standard a year ago, meeting the requirements of akkado for the stability of the equipment.

With this new power train, the new German submarine can travel more than two days under water quietly, or even more than four days at a quiet cruising speed. Moreover, during this period, it is not even necessary to expose the ventilation pipe to the surface, which makes the submarine really become an underwater God of war, rather than a diving warship. Since the submarine can float up and charge at one time and stay underwater for about 3 days, for the sake of submarine safety, most of the driving state of this new type of submarine will remain underwater, so the sharp bow design style is a bit out of date. As a result, the new submarine adopts a round bow design which is more in line with fluid mechanics. With more abundant power, the ultimate underwater speed of the new submarine can reach 17 knots, which is about three times that of the fastest submarine before. This speed can even support the submarine to pursue some merchant ships underwater, If conditions permit, it can almost track the enemy fleet underwater. In order to improve the speed of the submarine to the extreme, and to reduce the noise generated by the irregular parts underwater, this kind of submarine even cancelled the 88mm caliber gun in the bow for the first time, and designed the 40mm anti-aircraft gun on the command tower as a recyclable hidden type. It can be said that after this effort, This submarine is the quietest one today. Because of the increase of battery volume, a larger submarine volume is needed. Because the members are unable to air out of the water in most cases, they also need a larger space to reduce the pressure brought by the enclosed space. From another point of view, a larger volume also means that they can carry more supplies and more ammunition, So the displacement of the new submarine has reached an amazing 2400 tons, which is definitely a terrible underwater giant. The more rounded bow brings an additional benefit to this new submarine that could not be achieved before, that is, some sonar systems can be installed in the position with the widest coverage angle of the submarine, so that the submarine can find its target further and earlier underwater, and the dead angle is only the rear part of the submarine. If anyone remembers prion's battle in Scarpa Bay, they will criticize the u-47 submarine for its temporary loading capacity. Because it can't shoot enough torpedoes at one time, although the German submarine has more opportunities to create more brilliant achievements in that battle, it can't do so for technical reasons. Now, this phenomenon has finally been solved by the German submarine design technicians. The increased volume enables the new submarine to have the powerful firepower of six torpedo launchers in the forward bow position. In addition, the more professional torpedo chamber is equipped with the fashionable accessory loader. When the ammunition is sufficient, the new submarine can be equipped with a large number of torpedoes, The new submarine can fire all 18 torpedoes on standby in the torpedo cabin at one go, and can fire another volley 10 minutes later. When Donitz transferred prion back to Hamburg from the Spanish coastal port, prion and his men were reluctant. But when the military band left the dock, the engineers opened the hidden dock and revealed the new submarines inside, prion and his men were shocked by the super submarines in front of them. After the engineers explained the powerful functions of the new submarine to prion and his crew, prion took a look at general Donitz standing beside him. From each other's eyes, he could see what was in his eyes. Their souls were trembling for the birth of this submarine, because they had devoted their whole life to the submarine war, It's changed in this moment. And these people will witness this earth shaking change“ You are not only a battleship killer now, but also the fastest man who can run underwater. " Pointing to the new submarine, Donitz said with pride, "once this submarine starts to form a wolf pack, your Majesty the British emperor in Iceland will starve to death." Prion nodded. "I'll go out to sea tomorrow and let him eat vegetarian food for a few months before I starve him!"
