Transmigrated as the Crown Prince

Just as the US destroyer was desperately searching for traces of the submarine, the Tiger Shark submarine had already dived to a depth of fifty meters in the channel.

Naturally, you can't use the periscope to lock the target here, you can only rely on sonar.

Soon, the sonar crew heard a target. "Captain, 2,000 meters ahead, it's a big guy, at least 30,000 tons."

"Torpedo No. 1 is launched. Wire-guided torpedoes are loaded after launch."

Although sound-seeking torpedoes are useful in this situation, Yannik is strictly prohibited from using sound-seeking torpedoes frequently.

Because once the United States masters the characteristics of this acoustic torpedo, it will be easy to find a way to deal with it. In the original time and space, not long after Germany put the T5 sound-guided torpedo into actual combat, weapons experts from the Allied Powers proposed 14 countermeasures; the general idea was to "make a louder noise than where the warship is where our warships are not, in order to disrupt audio-visual”. After the noise makers they created were released, they induced the acoustic mines to pass through one noise maker after another until they left the target area.

Therefore, unless there is certainty that the entire opponent's army will be annihilated in a battle, a maximum of two sound-guided torpedoes will be used to avoid leaking the secrets of this weapon.

"boom!"

The torpedo hit the stern of the freighter hard and blew a big hole. Sea water poured into the ship frantically from this large hole. Fortunately, the ship's damage control team was well-trained and risked their lives by closing the doors of several watertight compartments, finally stopping the water intrusion. Although the hull has tilted slightly, the balance can be restored as long as the water pump is used to drain the seawater inside the ship. Only the propeller was blown away, so we had to wait for the tugboat to come and tow it away.

Three freighters in a row were attacked, and the entire waterway exploded.

"What are you bastards doing?! Why don't you find those damn submarines quickly?!"

"We work so hard to earn money and pay taxes to support useless trash like you?!"

"Having a dog is better than trash like you!"

All kinds of obscene curses filled the public frequency band, scolding the surrounding destroyers.

"!!" After turning around for a long time, he still couldn't find any trace of the German submarine. Brady's anger level had reached MAX. Now that he heard these curses, his whole body was shaking with anger, and the anger in his eyes seemed to burst out. "Sonar soldier! Did you find it?" The tone sounded like if the sonar operator said no, he would be torn into pieces.

The sonar operator replied tremblingly. "Sir, 14 degrees on the port side, 50 meters away, depth 70, I found a strange sound, not too strong, I'm not sure if it is a submarine." He repeatedly confirmed what he heard and used his Judging from experience, it is not a submarine, but more like a whale. But at this time, he didn't dare to say that he didn't find anything, so he could only vaguely give a target.

Sure enough, Brady's eyes lit up after hearing the sonar crew's discovery, and he immediately ordered the launch of depth charges.

As early as 1915, the United Kingdom developed the first depth bomb, which looked like a metal can for garbage. The can was filled with explosives and equipped with a hydraulic fuse and a trigger fuse. Depth bombs are initially thrown into the water by surface ships and can explode when they touch the submarine or at a predetermined depth. The huge pressure generated by the explosion can cause serious damage to submarines 10 meters away, and the depth of action can reach 200 meters.

Following Brady's order, the K-type depth bomb launcher installed on the destroyer (which can throw depth bombs 50-100 meters away from the ship's side) dropped depth bombs one by one towards the target.

A row of depth charges hit, and along with a series of explosions in the sea, the sonar also failed. The sound waves generated by the depth charge explosion took more than ten minutes to dissipate, during which time the sonar became deaf.

The sonar operator took off his earphones and rubbed his sore ears, and couldn't help but secretly breathed a sigh of relief. Even if the German submarine cannot be found after more than ten minutes, it can be said that it took advantage of the chaos to escape.

Inside the Tiger Shark submarine, the sonar operator reported to Kretschmer. "Captain, the other destroyer has dropped depth charges. The distance is more than 1,500 meters."

"These idiots." Kretschmer shook his head in disdain. Are they getting impatient? Just find a random place to throw depth charges?

At this time the torpedo room reported that the wire-guided torpedoes had been loaded.

This time the supply ship brought two of the latest new torpedoes equipped with wire-guided torpedoes.

As the name suggests, the wire guide transmits information through the wire between the torpedo and the launch platform. Before launching a general torpedo, you must input the target's orientation, speed and other shooting parameters before launching; while a wire-guided torpedo can find the target's approximate orientation and launch it first, and then the launch platform controls its course, speed, depth and attitude until the target is launched. Hit the target.

In the missile field, this correction is usually done by radio. But in the ocean, because the salty liquid like seawater is too conductive, radio signals are absorbed and depleted so much that they cannot be used at all.

The original space-time wire-guided torpedo was first invented by the Germans during World War II and was called the "Skylark" torpedo. After the war, the United States and the Soviet Union both developed their own families of wire-guided torpedoes on this basis. Early wire-guided torpedoes used copper wires with a diameter of less than 5MM wrapped with an insulating layer. However, this wire was too heavy. The weight of 100 kilometers of wire exceeded 50 kilograms, and some even weighed as high as 100 kilograms.

Fortunately, optical fiber has entered mass production at this time, and the use of optical fiber wires greatly reduces the load of the torpedo and improves maneuverability. When a torpedo is launched, the wires connected to the launching platform and the torpedo are released at the same time, and are continuously released as the torpedo moves forward, so that the wires are always suspended in the water and basically unstressed.

"emission!"

The wire-guided torpedo accurately hit the freighter that had lost power and was unable to move.

The first mate said excitedly after hearing the sonar man's report that the freighter was sinking. "This should be recorded. We achieved the first actual combat hit of a wire-guided torpedo in human history."

Kretschmer nodded. "Yes, it's worth writing down. It's a good thing." Using wire-guided torpedoes eliminates the need to risk death to gain position, which naturally improves the submarine's survivability. The most important thing is that compared with acoustic torpedoes that are easily interfered, wire-guided torpedoes have much stronger anti-interference capabilities - or in other words, there is no possibility of being interfered by the enemy at all.

Many ships on the channel turned around and fled this terrible place. As a result, the busy channel instantly became a mess, and several cargo ships even couldn't avoid it and collided with each other.

The public frequency band on the waterway became more lively now. The personal attacks at the beginning escalated to greetings to the female family members of the destroyer crew members (mainly the destroyer captain). Even the other party’s dog was not spared and was insulted for dozens of times. all over.

Ordinary people couldn't stand being scolded like this, let alone high-spirited soldiers; soon, the public frequency band became a battlefield for scolding, and some grumpy destroyer captains even turned their guns to scare the cargo ships, and the scene once got out of control.
