My Third Empire

Biquge www.wuxiaspot.com, update my latest chapter of the third empire as soon as possible!

Submarines of this era usually save about 3 to 4 knots under water, which is like a turtle. The speed of a destroyer is generally more than 30 knots. If the design of the newer ship is shorter, it can even exceed 35 knots. In other words, it is very easy for a destroyer to catch up with a submarine.

Of course, this data is calculated when the destroyer can really track the position. If you do n’t know the location of the submarine, the destroyer will not be able to catch up with a submarine that escapes with a different course no matter how fast it is.

"The other party is approaching!" The sonar soldiers were the eyes of the submarine underwater. The German sonar soldiers held the headphones with their hands. After a few seconds of silence, they frowned and reported to the Prienhui waiting on the side: The location where the torpedo was being fired just now is close, very accurate judgment. "

"..." Prien knew he was in trouble. Who could tell before the attack that the opponent would have a commander who was so proficient in anti-submarine warfare? The formation of the Soviet Fleet just now looks like a layman. As a result, the layman turned into a professional household in an instant.

"Change course, left rudder, avoid it!" After thinking about it, Prien decided to change the course to see the opponent's reaction. If it's just a stunned head start, Prion can even consider sinking his opponent and adding more of his own record. However, he did not expect the other party to come so fast. According to past experience, he did not leave the range of the destroyer sonar detection.

"Keep the speed down to 3 knots! Reduce the noise!" Prion continued to issue combat orders, and the soldiers turned off some unnecessary equipment to reduce the noise made by the submarine in the sea. But obviously in the sea water, the sound from the rudder and the engine and propeller is the main source of noise. Unless all the power systems are turned off, the probability of the other party discovering them is still very large.

But no one will really shut down all the power systems, so it will not take long to make the entire submarine, and if the enemy has not left, then their situation will be even more dangerous.

Prian waited quietly, waiting for his opponent to show his strength, so he could judge how to respond according to the strength of the opponent. Now that the initiative is in the hands of the faster destroyer, he must let his opponent move first so that he can find his chance.

On the surface of the sea, the sharp bow of the destroyer cut the waves, leaving a trace of his speed on the water. On the bridge, Captain Beard was judging where the submarine would appear now: "Sonar, haven't you found it yet?"

He determined his judgment, believing that he would not predict errors. The submarines of the German Navy must be found nearby. Submarines under water cannot be that fast. At least in his experience, they are not as fast as submarines.

"I found a strange signal source, not too strong, not like a submarine, but this signal is not like the sound of nature." Sonar confirmed the thing he heard repeatedly, still not sure what it was. , So had to tell the truth. The direction of the sound came from the right-angle side of the route, just on the edge of the largest range that the sonar could detect.

After hearing the sonar soldier's statement, the bearded captain's eyes lit up and immediately guessed the opponent's trajectory. It seems that this submarine is also an experienced guy. When he just confirmed that his destroyer was rushing over, he changed his route and almost avoided his sonar equipment.

This is not a good sign. It is definitely not an easy task to seize such a sophisticated opponent. Captain Beard immediately gave the order to turn, because if he didn't adjust his course, he would lose his target after ten seconds.

The destroyer turned suddenly on the sea, and pointed the bow at the position of the German submarine, which made the German sonar soldier a little nervous, thinking he heard the signal that his opponent was getting closer. For a submarine, the approach of the destroyer is definitely not good news. All the problems revealed in this news are deadly.

The other party's sonar rushed to catch the submarine, or the other party's amazing luck and various reasons for the mess, anyway, it was closer to each other. If the two sides are closer together, the destroyer can guess the position of the submarine through sonar. At that time, the battle becomes a pure slaughter.

The destroyer will go through multiple sonar monitors to confirm the course of the submarine, and then drop deep water bombs on the course of the submarine in advance. One after another the deep water bombs will be dropped by the destroyer, and then these powerful deep water bombs will explode in the deep sea, as long as The submarine will be immediately damaged and sunk within the explosion range.

It ’s ridiculous that the deep sea that protected the submarine from damage at that time immediately became a cold-blooded beast that engulfed it: the surface ship sank anyway, and there was still a process of fast or slow. Sinking in the water.

"Captain! They turned around and turned toward us, still approaching us." The sonar soldier raised his head and reported to Prienhui: "The distance between us and them has been shortened."

Prione wasn't ridiculous, he instantly judged the scope of the other party's sonar. This is the sonar of the United Kingdom. This distance was confirmed by the German submarine in the North Atlantic. Now that you know the approximate detection range of the opponent's sonar, during the subsequent escape, you can accurately calculate the opponent's blind spot range.

The first time the opponent rushed over, obviously based on speculation and judgment based on experience, this Prien could guess. The second time the opponent turned right with his submarine, it was definitely a real response that could only be made after the submarine was detected.

"Accelerate! To 5 knots!" Prien decided to do something. Since he could not escape, then throw it away: "Continue to the depth of the dive, set the depth after 50 meters! Then notify me!"

The noise is obviously much louder than before. The motor of the submarine started to work madly. Only a few emergency lights in the entire submarine were still dimly lit, and the rest of the place was dark, making the people inside more nervous and anxious.

"Turn! Left full rudder!" As if guessing that the other party had already caught up with him, Prian frowned and gave the order to turn. His defense strategy changed, and the originally quiet and slow rhythm was suddenly accelerated by the German submarine. A giant shark quiet in the deep sea began to accelerate, and frequently twisted his body.

The zigzag route, the basic navigation standard for submarines to get rid of destroyers, the core idea is to use their own variable routes to interfere with the destroyer's bombing, reduce the opponent's bomb hit rate, and then get rid of the opponent's sonar contact when possible and complete the escape the goal of.

Sure enough, as expected by Prien, on the top of his submarine, he had just overtaken the Soviet destroyer who had come forward, because at the command of the bearded captain, the sailors had pushed the deep-water bomb to the launcher ready to be thrown on. However, with the sudden acceleration of the German submarine, the command of the deep-water bomb bombing attack also became standby.

At this time, the Captain Beard also had a lot of troubles, because the underwater German submarine had no regular activity at all, and there is no regular state at all, that is, it is impossible to speculate on the state of the opponent's next move. This is not a good state for destroyers that must launch attacks in advance.

At the beginning, the bearded captain used the torpedo's attack direction to guess the approximate position of the Prien submarine. This was an important speculation that allowed the Soviet destroyer and the German submarine to maintain sonar contact. This is for the destroyer attacking the submarine. Vital. Otherwise, you do n’t even know where the enemy is, so why not talk about the follow-up question of attack?

Immediately following Prien's submarine has been moving at a constant speed, and the speed is not fast. This allowed the Soviet destroyer to quickly reach above the submarine and master the approximate depth of the submarine. But at the next moment, the German submarine suddenly changed all its states: the depth changed, the speed changed, and the route also changed.

As a result, the prepared attack method can no longer be used. Soviet destroyers must re-determine the submarine data of the other party to prepare for their attack: they must measure the new route of the submarine, and then confirm the submarine speed and route multiple times. To determine the approximate location of the opponent's next step, in order to launch the next attack.

The anti-submarine warfare limited to the times and weapons is simply unimaginable today. Today ’s submarines and destroyers sonar can accurately locate opponents, anti-submarine torpedoes and deep-water bombs can easily attack targets even more advanced anti-submarine missiles or submarine-launched anti-submarine Ship missiles come to attack opponents remotely. But in this era, everyone must use more complicated and inefficient methods to do everything possible to sink opponents.

"Left full rudder! Keep up with this submarine! Can't let him run!" The captain of the beard sketched 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 as soon as possible opponent.

After all, in the distance, more than 1,000 Soviet soldiers were soaked in the sea water because of the attack of this German submarine, and even hundreds of people have been frozen on the cold sea floor forever. The cruiser led another destroyer to salvage the fallen water, but because of the slow progress, many of the fallen water have been frozen to death in the cold water. What made the Soviets even more angry was the sinking ship, called the Soviet Union.
