In the command cabin of the XX-class submarine UA22, the sergeant wearing headphones sat in front of a radio-like device and only used the readings of various instruments in front of them to infer the location of the target at sea. This was a common way of combat at the end of the century, but it is still in the 40s. In the just-concluded world war, submarines of all countries used visual guidance to guide the attack, so submarines must be at the depth of the periscope when launching attacks. Although the Germans lost this war, they stood in pure technology

At the angle, they have achieved a large number of amazing war weapons with their unique scientific and technological ideas and R&D systems. This xxi-class submarine is a pioneer in the development of modern submarines. It has improved the battery capacity of German submarines in the past, with about Viic type, which greatly increases its underwater range and shortens the time required to float to the surface. Simply put, the xxi-class can be charged with 5 hours of snorkels and can have the ability to submarine continuously at a speed of 53 knots for 2 to 33 days without recharge.

;The xxi class is much quieter than the Viic type, and is less likely to be discovered during submarine sprinting; the xxi class hull is simple and smooth, which improves the submarine speed and reduces the submarine drag, making it harder to track and destroy. In addition, the space and equipment of the xxi class are larger and better than before. The large hull is equipped with multiple sets of batteries and still has room after it is equipped with refrigeration equipment and a shower room that seems too luxurious to the previous German submarines. It also has a special hydraulic torpedo system that allows assembly

The torpedo time has become very short (launched in 20 minutes | 88 torpedoes), and the new torpedo fires faster and has a longer range. The xxi class also has a more advanced sonar system, which can aim and fire torpedoes without using a periscope to increase its concealment. The xxi class submarine can store 23 torpedoes or 17 torpedoes and 2 mines, and its boat has 6 torpedo tubes at the beginning; the deck guns and multiple anti-aircraft guns in the past were reduced to a foldable and storage 20mm anti-aircraft gun.

Eliminated the previous steps of spinning around the periscope before the attack. After several days of going out to sea, the submarine commander, who gradually grew bearded, hugged his chest with one hand and his chin with the other. This time, his hair was combed smoothly and neatly, and his dark brown eyes were cheetah-like coldness and sharpness. After thinking for a moment, he ordered, "The main electric motor operates at full capacity, increase to the speed underwater! Turn right 0 degrees! The sonar keeps tracking, and the entire boat is on guard!"[]

The order then conveyed the cabins of this submarine with a submarine displacement of 21 in the most direct way. In terms of tonnage and size, the xxi class is equivalent to the so-called "fleet submarine" of the Japanese and American navy during the war, which is the main offensive submarine. However, the advanced technology it possesses was not randomly mixed, but the essence of the experience of the German Navy during the two world wars. At the Potsdam Conference attended by the heads of allies, the German submarine captured because of the end of the war became a delicious bun in the eyes of everyone.

When most German submarines were directly scrapped or sank on site, the allies would study the division of xxi-class submarines, two in the United States, one in the United Kingdom, one in France, and four in the Soviet Union. However, Western allies believed that the Soviet Union had obtained more xxi-class through undisclosed channels to strengthen its naval strength, and soon began imitation construction.

In this relatively calm sea area, the 11ˉa22, shaped like a black shark, completed the steering in a smooth manner, and its speed at full speed underwater reached an unexpected level; 17 knots!

At the same time, the two ships on the sea, giant transocean cruise ships and combat light cruisers, are both good sprinters. Even without using all their strength, they can easily reach speeds of more than 220 knots. If a fair speed competition is a competition, they can easily leave the underwater lurkers behind. However, when both sides temporarily live in this sea area in the way they encounter, the relative speed gap is not enough to be their reason to avoid attacks. Moreover, most people on the ship did not expect the danger to approach so quickly...

Five minutes later, the squad leader in charge of senior sonar on the submarine reported a new number; "Target No. 1........................................................................................................."

At this moment, almost every pair of ears in the command cabin was listening to these numbers. Although they did not directly control the command, they were able to understand the evolution of the situation and the distance of the battle opportunity based on their own experience and cognition.

The effective attack distance of the new torpedo at a speed of 45 knots is 0 meters, which is nearly twice as large as the traditional 07 torpedo. The track left on the water is smaller, and it can be called the sharpest sea hidden weapon. The bearded submarine commander turned to look at the combat diagram of the weapon commander on the white plastic board. On previous combat submarines, he should have used a periscope with the captain and calculated the appropriate attack angle. However, on the xxi-class submarine, the setting of the periscope was not cancelled. However, after many simulation exercises, people found that the most suitable position of the weapon commander should be next to the sonar soldiers. Combined with the calculated data, the real-time situation diagram was outlined with simple lines, and the auxiliary captain should determine the next trend of the submarine based on spatial imagination.

"Turn right again 0 degrees! The torpedo on the bow is loaded and ready to launch at any time!"

The preparatory attack command made everyone in the submarine feel excited. This was his first time in a year to commit a real attack operation, and it was another important effort to seek rise since the defeat of the Third Reich. The crew naturally did not want to make the tricks go wrong.

The captain walked forward slowly, putting his right hand on the sonar's shoulders. With the advancement of technology, he became the key to attacking the entire submarine at Shushi.

"Try to determine the direction of our ua23."

The magistrate who operated the sonar equipment nodded slightly. After a moment, he spoke, "It can only be determined that it is on our right side, with a distance of more than 10,000, and the sound is relatively weak. It should also be in a state of rapid underwater navigation, perhaps closer to the target No. 2."

It is not difficult to imagine that the sound of water waves caused by the propeller in the submarine is far less than that of the ships on the water. In the past, the real noise was motor noise, which was also one of the centers of gravity of the German Navy's research in the middle and late stages of the war. Even if the silent effect was not achieved decades later, it was already forward for conventional sonar equipment. If the main electric radar was turned off and only the silent radar was activated on the boat, it would be difficult to make a general judgment.

The captain looked at the white board and black lines in the weapon commander's hand, thinking about the direction of his companions. As early as the First World War, the captains of the German Navy had already realized the limitations of single-boat combat, and eventually, their outstanding representative, Carl.

Denitz evolved the lone wolf tactic into a sea wolf pack tactic that almost changed the end of the war. Under the influence of this tactical idea, during World War II, German captains became increasingly inclined to exert their group power, even the best sea hunters were no exception.

"Target No. 1 is turning, sir! Its rudder noise suddenly increases!" The sonar reported to his commander while mobilizing the knob on the equipment.

The weapon commander immediately judged, "It should be moving closer to the No. 2 target, do we want it......"

The bearded captain raised his right hand and signaled him not to say much. It is true that he can observe it with a periscope at the depth of the periscope, but it is likely that the suddenness of the attack will be lost.

In the quiet command cabin, although the atmosphere became solemn and tense, there were few fear and uneasiness. This was completely different from the situation where the German submarine troops were strangled by the joint sea and air force of the Allied forces in the late war and it was unsustainable. Of course, people know that the war is over and the enemy no longer maintains vigilance during the war. This is really an excellent opportunity to launch a surprise attack!

"The target No. 1 has a position of zero nine, and the estimated distance is 7,000; the target No. 2 has a position of two, and the estimated distance is 7,000. Sir!"

The data reported by the sonar officer is not a progressive increase or decrease, but shows irregular changes as the submarine itself and the two targets are adjusted. The bearded captain no longer looks at the whiteboard of the weapon commander, but raises his head and closes his eyes, deducing the situation on the sea in his mind. From the observation and aiming of the periscope to the orientation of the radar sonar, this is an important leap forward in the submarine combat mode. The process of adapting is difficult and bitter, but only those who follow the trend of historical development and walk before ordinary people can stand at the forefront of the times and become the best.

After two sips of tea, the captain ordered, "The front torpedo is expected to be launched in 0 minutes, and all the staff are ready!"

At the same time, the alarm ringtones on the British light cruiser have stopped. This is not to say that the emergency is lifted, but all personnel have arrived at their respective duty positions. During this period, the communication compartment on the ship sent a telegram to the local naval command in accordance with the captain's instructions, reporting that they had detected the close-range radar detection waves and asked whether they had aircraft and ships were performing missions nearby. The radar compartment closely monitored the radar waves that quietly appeared and disappeared, and launched a naval and air search with the radar of the ship; the combat department commanded the naval guns, torpedoes and air defense divisions to enter the state of war as quickly as possible, lifting the gun jackets, adjusting the gun positions, and transporting ammunition. The visible and invisible places were in a mess.

In addition, the sonar department - a disposable configuration of traditional cruisers, and the defensive components of modern cruisers located in the middle and front are also trying hard to monitor the situation under the sea. However, just as engineers initially excluded sonar from large warships, the ship's own engines and propellers are too loud, which seriously affects the judgment accuracy of conventional sonars. Moreover, there is a giant cruise ship that can be called a noise machine and fuel monsters not far away!

On the bridge, officers wearing white naval uniforms stared at the sea with concern. It would be fine if they were just a false alarm. If they really encountered an unexpected crisis, whether they could survive safely depends on the will of heaven...

"Oh God......... Gentlemen, look at the port side. The waves reflect a little, and it seems to be torpedo......"

A lieutenant, about thirty years old, faced the port side, and his panicked voice seemed a little sharp, sounding like a woman saw a mouse. Despite the displeasure, the officers next to him turned their heads in unison, and some even picked up the telescopes.

"God...is that a torpedo or a dolphin? Oh my god...fish~thunder!"

The last shout was filled with horror. The water marks on the port side of the ship were very different from the bubble-filled trajectory dragged by torpedoes in the past. Its originated mainly because of the wave marks rising from the fast-moving underwater objects, which were looming and elusive.

With the rapid steering alarm sounded, the light cruiser, which had a speed of more than twenty knots, quickly turned the steering action. The bow of the ship was slashed through the waves, leaving cool white water marks on the sea surface. The hull tilted with rapid steering, and the George Cross naval flag on the mast was also swaying wildly. Soon, the port side guns and cannons fired together. Although British naval ships have also conducted live-fire exercises on the Atlantic Ocean since the end of the war, they have never been

As busy as today, the guns and shells ejected sparked a lot of water on the originally calm sea surface, but they did not have the interception barrage with a tight schedule as the shooter wished. In a blink of an eye, the waiters on the ship found more torpedoes on the sea surface. They shouted in panic and tried to guide the ships to appropriately avoid and the guns and guns to intercept accurately. However, the torpedoes that were speeding in are too little time left for them.

"It's going to hit it!" Someone screamed in horror. Those with little experience would run in the opposite direction, instead of diving and escaping at this time. Some were extremely brave or too late to run away. While praying devoutly, they were staring at the attack weapons that were more agile than dolphins. Finally, the first torpedo passed by the ship's side, and some brave people looked into the water. The black torpedo was like a straight monster fish with white words in front.

"It's Russian!" someone said in shock.

Then someone asked in shock, "What is it written?"

The man turned his head and looked at his companion with incredible eyes; "Long live communism...

So his companions cursed resentfully, "These Russians who should go to hell!"

At this time, someone on the ship exclaimed again, "That one is heading towards the stern of the ship!"

On the bridge, most officers did not leave the dangerous open observation deck and they were at a loss for attack from which submarine, but at least one thing they could confirm was that the other party not only intentionally sunk themselves, but also prepared to kill the 50,000-ton giant cruise ship, because from the torpedo route, the two ships were in a relatively overlapping position.

"Call the French to turn immediately!" The white-bearded British captain roared like a lion. Although the signal soldiers immediately warned the cruise ship about two thousand meters apart in flags, the efficiency of its excessively huge body steering was really not satisfactory. At this moment, the British crew may think of the "Titanic", one of the most famous shipwrecks in British history, and also one of the most famous shipwrecks in world history!

Under the sea thousands of meters away, the black submarine has slowed down its navigation speed. This is not caused by the exhaustion of batteries, but to obtain a more stable and accurate attack state.

"｜Torpedo launch! Torpedo launch No. 22!"

Since the chance of attacking first was taken first by a companion who might have better position, the bearded captain couldn't help but feel a little regretful when he ordered the attack. Once the Third Reich rises again, this secret maritime attack will inevitably occupy an important position in its Nirvana process. Even if it is never made public, the participants will still become dazzling heroes within. Even if it is only a few seconds apart, the historical status of "first attack" and "follow the attack" is obviously a world of difference.

Through the sound transmission cylinder, the response to the "torpedo launch" in the front torpedo compartment was heard quickly. Except for the sonar, almost all the other personnel began to look at the watch and time.

The Sonar Chief suddenly reported, "There was an explosion! It was very likely that they hit one of the targets... and it was not possible that they could tell which one it was!"

After a while, people vaguely heard what he was talking about. Because it was far apart, it sounded like someone was beating a giant drum in the distance. The tone was not high, but it felt a sense of majestic excitement.

Sparse applause rang out in the cabin, and some people were drinking softly. Although it was not their own credit, it was the enemy of the empire after all.

At this time, the bearded captain urgently ordered, "Measure the target position!"

Chief Sonar focused on operating this very complex machine, and in a moment, he quickly reported the estimated number; "Target No. 1 is still moving, with a direction of zero five, and a distance of four thousand five; Target No. 2 is still moving, with a direction of five two, and a distance of six thousand five, and is moving quickly towards us."

The captain thought for a moment; "Switch off the main motor, start the cruise motor, turn right thirty degrees!"

As the speed slowed down, the efficiency of the submarine's steering also decreased. The sonar commander quickly retested the target's orientation. The relative displacement of the target No. 1 was only 500 meters, and the orientation changed in reverse to the left side of the submarine. The relative displacement of the target No. 2 reached 2,000 meters, and quickly entered the effective range of the torpedo from outside the torpedo range, and the angle figure quickly reduced to zero degrees on the front.

Although the submarine's submarine's submarine's submarine's depth has remained unchanged since the radar detection ended, the bearded captain still asked the helmsman to report the submarine's depth at this time, and the answer was "thirty-three meters".

The breath heard in the ears of the crew became rapid and heavy unknowingly.

"Only track target No. 2!" the captain ordered.

In a blink of an eye, the sonar Yichang reported in a slightly excited voice, "The target distance is three thousand, and the direction is zero three, and it is turning."

The depth of the torpedo was not greater than the draft of a cruiser before, and the captain directly ordered; "Torpedo No. 3 launch! Torpedo No. 4 launch!"

At this point, all the imitation Su torpedoes carried on the boat were launched. If you want to continue to launch an attack, you must use the German torpedoes normally carried on the boat, including high-speed trigger type and improved audio tracking type.
