Open an aircraft carrier to fight against Japan

Bierhoff frowned and said, "Are you sure?"

"Report to the captain, it is absolutely certain that this is the enemy's submarine."

When the officers around Bierhoff heard the "enemy's submarine", panic appeared on their faces, but Bierhoff didn't panic. He laughed and said, "What are you panicking about? Our Poseidon Blade, the diving depth is 100 meters, if the submarines of the Chinese Navy dare to dive here, the sea water will crush them into sandwich biscuits, and the sandwich is still human flesh, haha.”

The officer next to Bierhoff laughed, and Bierhoff ordered in a loud voice: "Dive at full speed and dive to a depth of 100 meters."

Poseidon's blade dived, and the sonar of the Zhuxian boat immediately detected it. The sonar chief immediately reported to Xie Tao. After hearing Xie Tao's regret, he ordered: "Dive down and pursue. The torpedo cabin, as long as there is a torpedo launcher If you have the opportunity, let me know immediately."

The Jade Boat dived after the Poseidon Blade. During the dive, the position of the Poseidon Blade kept changing rapidly. The Jade Boat never found a chance to launch a torpedo. The two sides went down from a depth of more than 50 meters. Dive to a depth of more than 90 meters.

Bierhoff glanced at the depth gauge, which was 90 meters, thinking that the Chinese navy's submarine would not dare to follow, so he complacently asked the sonar chief: "Are the enemy's submarines still following us?"

Poseidon Blade released a small towed sonar during its dive, which can detect the sound situation behind the propeller, so the sonar chief can hear the sound behind him, and he hurriedly reported: "The enemy submarine is still following us, It also dived to a depth of 90 metres."

"Impossible! How did the Chinese submarine dive so deep?" Bierhoff couldn't believe his ears, and everyone around him was surprised.

Bierhoff suddenly laughed and said, "Haha, I understand. The Chinese submarine must have taken a risk and used up its safety margin. We will dive for a while, and when we reach 120 meters, it will definitely not dare to follow."

When submarines are designed, all indicators have safety margins, such as diving depth. A type of submarine can dive to a depth of 150 meters, but when it is in use, it usually only dives to 120 meters or 130 meters. meters, leaving a safe diving depth of tens of meters, which is only used in emergencies.

The Poseidon Blade dived again, and soon reached a depth of 120 meters. At this time, the submarine was already a little unable to hold on, and the sound of "bang... bang" came from the shell from time to time, which was because the sea water pressed the shell to the ground. Distorted.

Bierhoff was a little worried when he heard the sound of "bang bang bang" from time to time. He picked up the communicator and asked the sonar chief: "Is that Chinese submarine still following us?"

"Report to the captain, that submarine is still following us."

"How is this possible, did you hear me right?" Bierhoff's voice was full of despair, "How could it be possible for a Chinese submarine to dive to a depth of 120 meters?"

"..." Sonar was speechless.

When Bierhoff panicked, the torpedo captain on the Zhuxian boat behind him reported to Xie Tao: "Captain, you can launch torpedoes now."

Xie Tao said in a deep voice: "Okay, two torpedoes, launch."

The torpedo commander immediately pressed the torpedo launch button, and two fish and four torpedoes rushed towards Poseidon's Blade one after the other. When the torpedoes were launched, a large amount of high-pressure gas would pour into the sea, producing a sound similar to the bursting of water bubbles, but it was more The bursting of the bubbles is much louder, and the large amount of gas creates many bubbles that pop in succession, making the sound so strange that sonarists call it a "shot."

The sonar chief of Poseidon's Blade also heard this sound, and he shouted anxiously to Bierhoff: "Captain, the enemy submarine has launched a torpedo."

Bierhoff hurriedly said: "Quickly, empty all the ballast water tanks and float up urgently."

The crew inside the Poseidon Blade immediately scrambled to empty the ballast tank. At this time, the sonar chief sent another message: "The enemy submarine launched two torpedoes, and they are expected to reach our boat in 5 minutes."

5 minutes?Bierhoff's heart relaxed a little. This time was enough for the Poseidon Blade to float up for a long time to avoid the torpedo. After 3 minutes, the Poseidon Blade floated up to 30 meters. Bierhoff Hof thought he had dodged the torpedo, but he didn't expect the sonar captain to send another message: "Captain, the torpedo is chasing us..."

"Boom", before the sonar chief finished speaking, a loud noise came from outside the hull. With the loud noise, the water pipe on the submarine burst with a "bang", and the water splashed down. , at the same time the battery compartment sent a message: "Report to the captain, there is a breach in the battery compartment, and a large amount of seawater poured in..."

Before the report was finished, there was another loud bang. This explosion was much more violent than the previous one. The entire Poseidon Blade was vibrating violently. Bierhoff was thrown out directly, with a heavy head. He slammed into the periscope stand, his head was bleeding, and he was unconscious.

Yusi torpedo is a heavy-duty torpedo with a caliber of 655 mm. It is filled with [-] kilograms of explosives. The Poseidon Blade directly hits two of them. There is no physiology. A large amount of seawater pours in. The Poseidon Blade quickly sank into the sea... …

The blade of Poseidon sank into the sea, and its sound signal disappeared on the Zhuxian boat. The sonar captain of the Zhuxian boat immediately reported: "Captain, we have sunk the enemy submarine."

Xie Tao hurriedly asked: "Are you sure?"

"Report to the captain, it is absolutely certain!"

Xie Tao smiled and said: "Very good, immediately inform the whole boat of this news."

As soon as the sonar chief reported the news of "sinking the enemy's submarine", the entire Zhuxian boat erupted in jubilation. In the midst of the elation, Xie Tao suddenly thought of something, and said in a low voice, "something is wrong", and the officer beside him hurriedly asked Said: "Captain, what's the matter, did you find something wrong?"

Xie Tao said in a deep voice: "Order the sonar room to summarize the track of the enemy submarine into a 'track time chart', and send this chart to me, as soon as possible."

The staff officer immediately conveyed the order. With the help of the computer, the sonar room quickly compiled such a track time map and sent it to Xie Tao. Xie Tao stared at the track map for a while, and suddenly commanded He slapped heavily on the blank space of the panel and said, "There is indeed a problem with the enemy's submarine. Hurry up and contact Riesling."

The staff officer said "Understood", and immediately ordered the sonar room to activate the sonar communication module. Sonar can be used not only for detection, but also for communication. However, the technology required for sonar communication is relatively high, and the British and Americans have not mastered it, so They came up with the "tow antenna" method.
