In a dockyard in the German port of Hamburg, dozens 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 war song.

In fact, the new submarine is now parked in the closed submarine dock, and the military band and the current crew have not yet seen this new equipment that claims to change the way submarines fight.

"General Dönitz, can this new type of submarine really change the mode of operation of the submarine force in the case of ocean-going operations as conceived?"

Accompanied by the sound of military music, Marshal Raeder gently leaned over Dönitz's ear and asked such a question.

Field Marshal Raeder looked very good in a black admiral's gown with a double row of gold buttons.

After all, under his command was a powerful fleet that defeated the world's first navy, and it is not an exaggeration to say that he was the most successful senior naval commander in the whole of Germany since its birth.

Although most of these achievements are not directly related to him, during his tenure as supreme commander of the Navy, the German Navy achieved terrible results that terrified the whole world.

He was already at the pinnacle of the entire Imperial Navy, and the battleship Marshal Raeder, which bears his name, can even be said to be the first real battleship in the German Navy since it was newly built.

Dönitz nodded, he was the commander who had gone through the whole process of testing the new submarine, and he personally witnessed the whole process of the submarine from birth to development.

Because of the key breakthrough in material technology, this submarine is destined to be the representative of the highest technology of this era, and it is also destined to be forever engraved in the history of human weapons development because of its terrible performance.

"The power system is a completely new and terrible system that allows the submarine to go underwater for a long time."

Dönitz tried to explain this German naval superweapon to Raeder in a language that was not very secretive: "The birth of this submarine marks the real development and maturity of the submarine from today. This is the real submarine. ”

"Such a big change? What is a real submarine called? Wasn't it a real submarine before? Raeder paused and became even more confused, and he looked at Dönitz, waiting for a more understandable explanation.

Dönitz smiled even brighter, after all, the weapon was enough for him to devise more terrifying wolf pack tactics and a more desperate strangulation system.

"Marshal, in the past, the weapon we piloted could only be said to be a diving water weapon, but now this submarine is, to put it simply, an underwater weapon that can surface."

"Does it make a difference?" Raeder still didn't understand the difference between the two, but he realized something immediately, and without waiting for Dönitz to show off his new toy, he asked, "You mean...... This submarine is mainly underwater? ”

"Yes, Marshal." Dönitz nodded triumphantly and said proudly

"This submarine can dive far, far away, and it can dive for a long, long time. Underwater speed ......"

He lowered his voice, pressed it to Raeder's ear, and whispered a number: "More than 15 knots." ”

"Shhh Raeder couldn't help but take a cool breath.

The temperature in the Hamburg military port in October was very low, so he inhaled so violently that his lungs were a little irritated, and he coughed violently: "Ahem! Cough! Ahem! ”

The performance of the military band has not stopped, and in the German Navy submarine formation, the submarine commander Prienli, who has achieved great results, was standing there, when he suddenly saw Admiral Raeder not far away suddenly coughing violently, and he did not know what kind of stimulation he was under.

"Ahem!" After coughing, Raeder looked at Dönitz, frightened by his words.

As a commander of the Navy's surface ship unit, Raeder was very familiar with the rules of the fleet's anti-submarine warfare, and he knew what a speed of 15 knots meant for a submarine.

In this era, almost all surface ships installed sonar was not accurate, and could only roughly detect the location of submarines, and then use the relatively large blast radius of mines to compensate for the lack of attack accuracy.

The speed of the submarine has now increased by a full three times, which means that the approximate position of the submarine can no longer be used as a basis for attack by surface ships - from the moment the depth charge is dropped, the submarine is already out of the effective radius of destruction of the depth charge.

The bow of World War II submarines was designed to be sharp, in large part because the submarine had to sail on the surface for more than half of the time, so it was designed to reduce driving resistance as much as possible, thereby improving the seaworthiness of the submarine.

However, this is obviously not designed for long-term underwater driving, and the operating power of the battery under water is really not flattering, so the underwater speed of World War II submarines is maintained at a speed of about 5 knots in most cases.

However, under Reinhardt's prompting, the new trendy thing of fuel cells was secretly and successfully developed as early as during the Soviet-German cooperation, and after ten years of technical reserves, this new type of submarine underwater power finally reached the design standard a year ago, meeting Reinhardt's requirements for equipment stability performance.

With this new power system, Germany's new submarine can travel quietly underwater for up to two days, and even more than three days underwater if driven at a quiet cruising speed.

The important thing is that there is no need to even expose the ventilation tube to the surface during this period, which makes the submarine a real underwater god of war, and it is no longer a battleship that can dive.

Since the submarine only needs to float once to recharge, it will stay underwater for about 3 days, for the sake of submarine safety, this new submarine will keep it underwater for most of the time, so the sharp bow design style is outdated.

As a result, the new submarine adopts a more hydrodynamic round bow design, and after having more powerful power, its underwater limit speed can even reach 16 knots, which is three times the fastest speed of the previous submarine.

Such a speed even allows the submarine to have the ability to pursue a part of the merchant ships underwater, and almost to track the enemy fleet under water, if conditions permit.

In order to increase the speed of the submarine to such a high speed, and to reduce the noise generated by irregular parts underwater, this new submarine has made a number of unprecedented changes.

For example, the bow 88mm cannon was eliminated, and the 40mm anti-aircraft gun on the conning tower was designed to be more discreet and recyclable.

After all these efforts, this submarine is enough to be called the quietest submarine at this stage.

The renewal of the battery also allowed it to increase in size, so a larger submarine volume was necessary.

Since members are unable to ventilate above the surface in most cases, a larger space is also needed to reduce the mental stress of the enclosed space on the submariners.

On the other hand, the larger size also means that the submarine has the ability to carry more provisions and ammunition, and with such a design idea, the new submarine has a staggering displacement of 2,350 tons, making it a rather terrifying underwater monster.

The rounded bow also brings a previously unimaginable benefit to the new submarine, namely that a part of the sonar system can be installed in the submarine's widest coverage angles.

This allows the submarine to detect the enemy earlier and farther under the water, and the last dead end is only the stern.

Benefiting from the increased size, the new submarine has a powerful firepower of six torpedo launchers in the forward bow position.

In the more professional torpedo compartment, it is equipped with such fashionable gadgets as auxiliary loaders. With sufficient ammunition, the new submarine can empty 18 torpedoes on standby in the torpedo compartment in one go, and deliver a new salvo strike in less than 10 minutes.

When Dönitz transferred Prien back to Hamburg, Germany, Prien and his men were somewhat reluctant. But as soon as the military band left the dock and the engineers pulled out the dock to reveal the new submarine, Prion and his men were immediately shocked by the supersubmarine in front of them.

After the engineer had finished explaining the power of the new submarine, Prien glanced at General Dönitz, who was standing beside him.

In the eyes of the other party, what he saw in his eyes, their souls were trembling with excitement for the birth of this submarine, and the situation of submarine warfare, for which they had devoted their whole lives, was changed at this moment.

And these people will personally witness this earth-shaking change.

"You're no longer just a battleship killer, you're the fastest man underwater." Dönitz said proudly as he looked at the new submarine.

Different from the XXI submarine in another time and space, Germany directly evolved the shape of the bow part of the submarine to similar to the Chinese Type 033 conventional submarine in the 60s, instead of the sharp bow design of the XXI submarine.

This also made the latest German submarine data appear for the first time on the strange phenomenon that the surface speed is not as fast as the underwater speed, completely subverting the design concept of the traditional submarine "boat that can dive".

The same improvements were made in the reduction of anti-aircraft guns and other weapons, and now the number of Allied aircraft in the Atlantic Ocean was not large, and in order to compromise underwater quietness and speed, this new submarine left only a 40 mm caliber anti-aircraft gun with a rather limited firing range, which was also different from the XXI submarine in another time and space.

Another terrible change is in the bow sonar system, which benefits from Reinhardt's systematic weapons technology stockpile a decade ago.

Germany has not taken a single detour in many weapons design, and the development and research that has invested manpower and material resources is also moving in the right direction.

Coupled with Germany's consistent leadership in science and technology, it has created a large number of world-leading advanced electronic equipment, of which radar and sonar are a part.

As a result, this new type of submarine, with a relatively large internal space, has been endowed with more advanced electronic equipment, as if it has become the true ancestor of modern submarines.

The sonar system in the bow gives it the ability to launch torpedoes directly underwater for direct attack, and it also became the first submarine in the world to launch torpedoes directly to attack targets without periscope-assisted aiming.

It is also equipped with a small collapsible radar antenna that can search for enemy ships within 35 kilometers of the sea surface and warn of aircraft within 85 kilometers of the sea.

Combined with this achievement, the maximum depth of 200 meters makes this submarine an underwater killer that is almost impossible to hit with today's technology.

Of course, this is an integral part of a plan to modernize the German navy, which in the future will be based on three types of ships.

One is an anti-submarine anti-aircraft missile destroyer and a cruiser with escort as its main function, one is an aircraft carrier as the core combat strength, and the last is an ocean-going submarine.

This direction of development, which has long been proven to be correct, allowed the Germans to skip the gap between the battleships that they could not catch up with in their own development, and in one fell swoop pulled the world's navy into the era of the air fleet with aircraft carriers as the core.

It also turned the originally weak German Navy into a first-class navy, and then defeated the powerful Royal Navy of the British Empire.

Today's naval warfare has long been unrecognizable, the era of big ships and huge guns has begun to gradually come to an end, and the era of air fleets, pioneered by emerging naval powers such as Germany, Japan, and the United States, has quietly walked ahead of the world.

Of course, those madmen in the Tokyo base camp who are clamoring to knock on the door of the West Coast of the United States with the main guns of battleships cannot be counted within the scope of the progress of the times.

But after all, the scene of using naval guns to penetrate the armor of enemy ships is too charming, so some people can understand the idea of the supremacy of naval guns.

After all, not everyone can follow the old war experience like Reinhardt and clearly find out the direction of future weapons development, which is the best model that other world powers can choose.

Every great power has its own experience of war.

Germany was defeated in World War I, and Germany began to reflect on its own shortcomings, and the Treaty of Versailles lagged behind Germany's military scientific and technological progress, which made the development of German military science and technology blind and inexperienced.

That's what gives Reinhardt a chance to intervene and change. As for the victorious powers, they are more correct in their own direction, believing that they are in the right direction.

Only a nation that continues to innovate and a country that continues to make progress can be worthy of enjoying the foundation of eternity and can stand on top of the world without being dragged down. This truth has been verified by countless once glorious imperial dynasties for future generations.

Just as the Japanese top brass had always firmly believed that battleships could defeat aircraft carriers before Pearl Harbor, because they had only risen to prominence 30 years by relying on large ships and huge guns, they still took it for granted that they had learned from their previous experience.

From the perspective of Germany's scientific and technological development path, its path is completely opposite to Japan's. Germany regards scientific and technological development as the most important part. Now even equipment manufacturing based on automated industry has begun.

In the era when there were no computers, this kind of automated production workshop based on mechanical direction did not reach the level of automation in reality as imagined.

However, it can also be said that it is a leap forward in industrial development and civilization, which marks the beginning of Germany's fast track to increase industrial capacity, and the slight advantage of the United States in this area is now being overtaken by Germany.

In Reinhardt's view, the most important development was the development of the entire industrial base of Germany, which was the improvement of the energy conditions of the Third Reich and the initial success of the integration of industrial production capacity throughout Europe.

Reinhardt didn't want a short-lived empire. What he wants is a Third Reich that will last for thousands of generations, an empire that can last until the time before he crosses over. As long as this is the case, the large number of preparations he made before that have nothing to do with this war, but are related to the individual, can be effective......
