Chapter 562

In this era, submarines can save electricity underwater at a speed of about 3 to 4 knots. To put it bluntly, they are no different from turtles. The speed of a destroyer is generally more than 30 knots. If the design of a new destroyer is short, it can even exceed 35 knots. In other words, it's very easy for a destroyer to catch up with an underwater submarine.

Of course, this data is calculated when the destroyer can really chase the right position. If you don't know the location of the submarine, no matter how fast the destroyer is, it can't use a different course to catch up with a submarine on purpose.

"The other side is approaching!" Sonar soldiers are the eyes of submarines under water. German sonar soldiers hold earphones in their hands. After a few seconds of silence, they frown and report to prienheir who is waiting on one side: "the other side is approaching the position where we just launched torpedoes. It's a very accurate judgment."

"..." prien knew that he was in trouble. Who could judge that the other side would have a commander who was so proficient in anti submarine operations before the attack? Just now, the formation of the Soviet fleet was just like a layman. As a result, the layman turned into a professional in an instant.

"Change course, full left rudder, avoid it!" After thinking about it, prion decided to change the course and see the reaction of his opponent. If it's just a blustered young man, prion can even consider sinking his opponent and adding more achievements. However, he did not expect the other side to come so fast. According to past experience, he did not leave the range of the destroyer sonar detection.

"Keep your speed down to three knots! Reduce the noise Prion continued to issue operational orders, and the soldiers shut down some unnecessary equipment to reduce the noise of submarines in the sea. But obviously in the sea, the noise from the rudder, engine and propeller is the main source of noise. Unless all the power systems are shut down, the probability of the other party finding them is still very high.

But no one will really shut down all the power systems, so the whole submarine will not last long. If the enemy has not left by then, they will be in a more dangerous situation.

Prion quietly waiting, waiting for the opponent to show his strength, he good according to the opponent's strength to judge how to deal with. Now the initiative is in the hands of the faster destroyer, he must let the opponent move first, so as to find his own opportunity.

On the sea, the sharp bow of the destroyer cut the waves, leaving traces of its own speed on the water. On the bridge, Captain bearded is judging the position of the submarine: "sonar soldier, haven't you found it yet?"

He was firm in his judgment and believed that he would not predict mistakes. You can definitely find German Navy submarines nearby. Submarines under water can't be that fast. At least in his experience, they don't have submarines that fast.

"I found a strange signal source, not very strong, not like a submarine, but the signal is not like the sound of nature." The sonar soldier repeatedly confirmed what he heard, but he was still not sure what it was, so he had to tell the truth. The direction of the sound is the right angle side of the route, on the edge of the maximum range that the sonar can detect.

When Captain bearded heard what the sonar soldiers said, his eyes lit up and he immediately guessed the course of action of the other side. It seems that this submarine is also an experienced guy. When it was confirmed that its destroyer was speeding up, it changed its course and almost avoided its sonar equipment.

This is not a good omen. It is definitely not easy to catch such an experienced opponent. Captain bearded immediately gave the order to turn, because if he did not adjust his course, he would lose his target in ten seconds.

The destroyer swerved suddenly on the sea, and the bow of the destroyer was aimed at the position of the German submarine, which made the German Sonarman a little nervous, thinking that he heard the signal that his opponent was getting closer and closer. For a submarine, it is not good news that the destroyer is getting closer and closer. All the problems revealed in the news are fatal.

The other side's sonar captured the submarine, or the other side with amazing luck, there are all kinds of messy reasons, anyway, it is to shorten the distance between each other. If the two sides are closer, the destroyer can guess the position of the submarine through sonar. At that time, the battle becomes a pure massacre.

The destroyer will confirm the route of the submarine through sonar monitoring for many times, and then drop depth bombs on the route of the submarine in advance. One by one depth bombs will be dropped by the destroyer, and then these powerful depth bombs will explode in the deep sea. As long as the submarine is within the explosion range, it will be damaged and sank immediately.

Ironically, at that time, the deep sea, which protected submarines from damage, immediately became a cold-blooded beast that devoured them: there was a fast or slow process for the sinking of surface ships. There was no need for the submarine to sink excessively. It was originally submerged in the water.

"Captain! They turn around and are still close to us. " The Sonarman raised his head and reported to prienway: "we are getting closer to each other."

Prion is not a false name, he immediately judged the coverage of the other party's sonar. This is a British sonar. This distance has been confirmed by German submarines in the North Atlantic. Now that we know the approximate detection range of the opponent's sonar, we can accurately calculate the blind spot range of the opponent in the later escape process. The first time the opponent rushed over, it was obviously based on the speculation and judgment of experience, which prien could guess. The second time the opponent followed his submarine to make a correct turn, it was definitely a real reaction after he had detected the submarine“ Speed up! Five knots Prien decided to do something. Since he couldn't get away from it, let's get rid of it: "continue to dive to a depth of 50 meters! Then let me know! " The noise was much louder than just now. The motor of the submarine began to work crazily. Only a few emergency lights in the submarine were still dim. The rest of the place was dark, which made the people inside more nervous and anxious“ to turn to! Left full rudder As if he had guessed that the other side had caught up with him, prion frowned and gave the order to turn. His defense strategy changed. The original silent and slow rhythm was suddenly accelerated by the German submarine. The silent giant shark in the deep sea began to accelerate and frequently twisted his body. Zigzag route is the basic navigation standard for submarines to get rid of the pursuit of destroyers. Its core idea is to use its own changeable route to interfere with the bombing of destroyers, reduce the opponent's hit rate of bombing, and then get rid of the opponent's sonar contact when possible to complete the purpose of escape. As prien expected, on the top of his submarine, just catching up with the Soviet destroyer, the sailors had already pushed the deep-water bomb to the launcher ready to throw under the command of Captain bearded. However, with the sudden acceleration of the German submarine, the order of the deep-water bomb bombing attack also became standby. At this time, Captain bearded also had a lot of troubles, because up to now, the activity of this underwater German submarine has no rules at all, and the state without rules is that it is impossible to speculate the state of the opponent's next action. This is not a good situation for destroyers who have to attack in advance. At the beginning, Captain bearded used the attack direction of the torpedo to speculate about the position of prion submarine. This is an important speculation, which made the Soviet destroyers keep sonar contact with German submarines, which is very important for destroyers attacking submarines. Otherwise, you don't know where the enemy is. How can you talk about the follow-up problem of attacking? Immediately after that, Prynne's submarine kept moving at a constant speed, and not very fast. This allowed the Soviet destroyers to quickly come to the top of the submarine and master the approximate depth of the submarine. But the next moment, the German submarine suddenly changed all its state: the depth changed, the speed changed, and the course changed. As a result, the prepared means of attack can no longer be used. The Soviet destroyer must re determine the data of the opponent's submarine to prepare for its own attack: it must determine the new route of the submarine, and then confirm the speed and route of the submarine for many times to judge the approximate position of the opponent's next step before launching the next attack. Limited to the era and weapons of anti submarine operations are almost unimaginable today, today's submarine and destroyer sonar can accurately locate the opponent, anti submarine torpedoes and deep-water bombs can easily attack the target, and even have more advanced anti submarine missiles or submarine launched anti-ship missiles to long-range attack the opponent. But in this era, we must use more complex and inefficient methods to try our best to sink our opponents“ Left full rudder! Keep up with this submarine! Don't let him run away Captain bearded outlined on the chart with his fingers, hoping to grasp the opponent's law of action as soon as possible, so as to sink this cunning opponent as soon as possible. After all, in the distance, more than 1000 Soviet soldiers were immersed in the sea because of the attack of the German submarine, and even hundreds of people were frozen in the cold sea for ever. The cruiser and another destroyer are rescuing the fallen, but because of the slow progress, many of them have been frozen to death in the cold water. What made the Soviet Union even more angry was the sunken warship, the Soviet Union.
