Transmigrated as the Crown Prince

Soon a report from the sailors came from the torpedo room. "All torpedoes ready!"

At this time, the fleet had entered the optimal range of torpedoes.

"These idiots!" Kretschmer couldn't help but sneered. He didn't know whether it was because he relaxed his vigilance because he was close to his own coastline, or because he believed that German submarines could not break through the outer defense circle. In short, this fleet did not adopt a standard anti-submarine formation. , but just lined up in such a big way, they were like real targets; even in the previous training, they had never encountered such an easy target. "Launch torpedo No. 1 and No. 2!!"

The two torpedoes that rushed out of the torpedo tube rushed forward for a minute, and the sound induction mechanism in the head was activated. The density of seawater is higher than that of air, so the propagation of radio waves in seawater will be affected to a certain extent, unlike radio waves that can propagate very far in air. But seawater also has a characteristic. Sound propagates faster in water than in air, about 4 times faster! This characteristic made the sound induction mechanism immediately discover the fleet in the distance and pounce on it without hesitation!

After a few seconds, Kretschmer ordered again. "Launch torpedo No. 3 and No. 4!!"

Torpedoes No. 1 and 2 are sound-guided torpedoes that can track targets on their own after being fired, but torpedoes No. 3 and 4 are ordinary torpedoes. Hitting a moving target several kilometers away requires extremely precise calculations.

Friends who have played the fully realistic Hunting and Submarine series basically understand this process. The first step is to determine the type of the opponent's ship according to the atlas to further determine the target's mast height. (Although Kretschmer did not know the specific data of this new battleship, other countries also built Washington Treaty-type battleships, and he used those battleship data as a reference.)

The image size of the target in the sight obtained by the sextant range measurement can be converted proportionally to the height of the mast to obtain the distance to the target. After multiple distance measurements, the target's course and speed can be measured on the chart. Input these data into the aiming computer (although there is no electronic computer, there is a purely mechanical computer), so that when the target is aligned in the sight, the torpedo will set the launch angle of the torpedo based on the calculated prerequisites to allow it to hit the target.

But there is another problem here, that is, the target must maintain a constant speed and change direction for several minutes. Therefore, the submarine must remain concealed, otherwise the enemy will be alert and use zigzag evasive navigation, which will be difficult to hit. This is why it was submarines, not destroyers, that used torpedoes to achieve the most results at that time.

After firing four torpedoes, Kretschmer did not stay where he was and watch the show, but ordered the submarine to turn 90 degrees and leave. He said while looking at the stopwatch. "His Highness has asked us to sink at least 20,000 tons of battleships. Sinking this battleship has already completed the mission." He estimated that the tonnage of this battleship was only 30,000 tons, which was considered a successful completion of the mission.

The first mate on the side said doubtfully. "So what do you want?"

"I think we can eat the remaining two cruisers and four destroyers. Including the supply ship, we can sink them all with up to 10 torpedoes."

The first mate shrugs. "You are the captain, you have the final say."

At this time, torpedo No. 1 and No. 2 had already approached the fleet. Electric torpedoes have the characteristics of low noise and no track. Even ships equipped with good sonar equipment can hardly detect the torpedoes in time and avoid them. The sound induction mechanism on the torpedo head firmly locked on the North Carolina, which was the most noisy in the formation, and slammed into the rear of the battleship.

"Boom! Boom!"

The first torpedo hit the rapidly rotating propeller and exploded violently!

A second later, the second torpedo also hit, blowing away the propeller system and stern rudder.

The huge impact made the captain on the bridge, Colonel Hestvedt, almost knocked down. He subconsciously held on to the handrail next to him and shouted loudly. "What's going on?!" As soon as he finished speaking, he felt keenly that the ship's speed suddenly slowed down, and it was obvious that the power system had been severely damaged.

Under attack!

The most likely thing was a torpedo attack! !

But how could a torpedo appear here?

It's a submarine!

Colonel Hustvedt immediately thought of the German submarine. It must have been a German submarine that sneaked in and fired the torpedo without anyone noticing!

Damn it, what do the perimeter defenses do? ! There are more than 1,200 kilometers of internal and external defense lines here! He actually let German submarines come over to lay an ambush? !

Just when he was about to issue an order for the destroyer to search for enemy submarines, a dull explosion suddenly came from beneath his feet. Colonel Hustvedt was thrown away by the violent shaking, and his face was hit hard on the hard floor. Streams of hot liquid flowed from his forehead and nostrils. The entire bridge was instantly in a mess, with painful groans everywhere.

Just as Colonel Hestvedt was about to struggle to get up, another explosion sounded, and the huge impact threw him up more than one meter high, and he fell hard to the ground again.

"Wow!" The smell of blood surged into his throat, a mouthful of blood protruded, and his vision gradually blurred.

The huge energy generated by the explosion tore apart the battleship's not-thick bottom armor, and the keel structure supporting the ship inside was twisted and deformed.

Tons and tons of seawater poured in crazily along the cracks, pushing the twisted and deformed walls through the gaps and all the holes that could be found, crazily occupying one territory after another that originally belonged to the air. Most of the damage control personnel inside the ship were swept away by the influx of seawater. Accompanied by the harsh twisting sound of steel bars, this latest battleship, which had just entered service, began to tilt slowly.

When the sea water squeezes a large amount of air out of the interior of the ship, the entire battleship will be overwhelmed, pulling more cabins into the water, and the vicious cycle continues until the entire ship sinks to the bottom of the sea. Just two minutes later, the inclination of the hull exceeded 30 degrees.

The cruiser following closely behind witnessed all this, and the captain of the cruiser was shocked and kept calling the North Carolina with a radio. "North Carolina! North Carolina! Your ship has listed seriously! It is recommended to abandon ship! Do you hear that?! It is recommended to abandon ship immediately!!"

After calling a few times, he suddenly thought of something and hurriedly ordered. "There is a German submarine nearby. Let the destroyers search the entire sea area! Sink it!" Rescue is a must. There are more than 2,000 officers and soldiers on the North Carolina. Even if half of them are killed, there are still 1,000 people. They can't just die without rescuing them. But if the surrounding submarines are not dealt with, the rescue work cannot be carried out normally.

Because of the stealthiness of electric torpedoes, no one noticed which direction these torpedoes were fired from. The four submarines could only circle around the surrounding waters like four headless flies, trying to find that damn submarine. He also threw depth charges indiscriminately.
