Chapter 1800 Acoustic Homing Torpedo

Sonar buoys, which appeared in World War II in history, were technical countermeasures to curb the Germans' increasingly large submarine superiority. They were first invented by the United Kingdom.

Now, Germany has made great progress in electronic technology, and this sonar buoy detection device has also matured.

For the fleet, the enemy's submarines are a great threat. The submarines of this era are absolutely nonsense in combating submarines. Only surface ships are the main force of anti-submarine. Therefore, anti-submarine helicopters appeared in this situation.

As the signal was detected, the captain did not hesitate and immediately ordered the anti-submarine torpedo to be thrown!

Under the short wing on the left, the T5 electric torpedo left the pylon, and because of its low altitude from the sea, it fell into the water almost after being thrown.

To deal with underwater submarines, if you use depth charges, it is quite wasteful. After all, this thing is almost entirely dependent on Mongolia. If it is a surface ship, it can carry more quantity, and the waste is not terrible.

However, the anti-submarine helicopter will not work. After all, it has a limited carrying capacity. Although it carries a part of anti-submarine depth bombs, it will use the latest torpedoes it carries whenever possible.

The T5 electric torpedo is improved on the basis of the T3 torpedo. The biggest change is its seeker. This is the first generation of German and the world's first acoustic homing torpedo, also code-named G7ES.

Underwater, radar cannot be used. The only thing that can be used is sound. Now, all warships have used sonar as the main means of underwater detection.

If the sonar is installed on the torpedo, so that the torpedo can automatically find the direction of the sound, and then attack, so that it can be easily attacked?

The idea is simple, but turning this idea into reality requires technical support.

Even if it integrates the power of the whole of Europe and invests in technology, Germany has developed this first-generation acoustic homing torpedo, which has initially achieved this goal, and it is only carried by helicopters.

Why?

Because it does not distinguish between enemy and foe, although the target data is bound to it when it is launched, after the launch, the target is lost due to various reasons. When searching again, it is likely to attack its own warship as a target. Well, historically, this torpedo has done this more than once.

But now, with anti-submarine helicopters, there is no need to be afraid. The sea area where the helicopters fly out must be at a certain distance from your own warships. For example, now, just outside the maximum range of torpedoes, you don’t have to worry about accidentally hitting your own warships. You can finally rest assured. used.

Compared with the historical T5 torpedo, it has been improved, in addition to anti-ship, it can also be anti-submarine. In fact, the difference between anti-ship and anti-submarine is the problem of torpedo depth setting. After adopting the acoustic homing technology, the parameter of torpedo depth setting can be removed.

"Pfft!" The torpedo splashed down and entered the seawater. When it entered the seawater, the propeller at the tail began to turn, and the acoustic self-guided device at the head accurately captured the submarine at a depth of several tens of meters.

The advantage of the helicopter lies in its strong maneuverability. Just after capturing the signal of the target, it begins to maneuver, almost dropping bombs behind the target.

At the same time, the sound of the torpedo falling into the water was also heard by the underwater submarine. At this time, the other party had just dived to a depth of 100 meters, and then leveled.

"They dropped something again. This time the sound was louder, it might be a depth charge," the sonarman said. Turn!

"They're still down the torpedo!" the sonar operator cried anxiously. "It's coming to us!"

The enemy actually threw a torpedo! And our side is at a depth of 100 meters. Could that torpedo drill down below?

When he heard this, Captain Bill frowned immediately, and for him, it was puzzled at this time.

Even the United States does not have self-guided torpedoes now. At most, they use the sonar of submarines. When the periscope is not used to visually search for the target, the torpedoes are hit according to the data provided by the sonar. Come for a submarine.

Now, the Germans have torpedoes to hit their own submarines, so how did they set the torpedo parameters? Generally speaking, this is simply impossible!

beyond their common sense.

"The torpedo is swimming towards us!" the sonar operator continued.

Are the torpedoes still coming?

"Attention, the engine stops, keep silent." Captain Bill shouted loudly, at this moment, he could only speculate.

If the depth charge came from above, he had better leave this position to avoid accidental injury, but now it is the torpedo. If this torpedo can catch up with his side, it can only rely on the sound.

Yes, it is the sound, the opponent's torpedo can hear the sound of its own, and then chase after it!

There was no other choice but to give Captain Bill a try.

The motor at the rear stopped, the propeller stopped stirring the water, and the squeaking sound disappeared. At the same time, everyone on the boat stayed in their positions and did not make any sound.

They are strictly disciplined, and on the submarine, any negligence could put everyone in danger, and now, they are all waiting for the last moment.

The sonar operator was still maintaining high tension, listening to the sound inside the sonar, the torpedo was getting closer and closer.

"It's still approaching us," said the sonar operator.

Captain Bill didn't speak, he was gambling too.

The current situation is beyond their common sense. The torpedo actually penetrated 100 meters below the sea water and wanted to attack their submarine. Now, they have kept silent and can only wait.

At this time, turn on the motor to escape? That's stupid, since Captain Bill has made a decision, he won't change it easily.

The T-5 torpedo was still moving forward. At this time, it could no longer hear the sound in front of it and disappeared in an instant. Therefore, it could only sail by inertia according to the sound just now.

The torpedo continued to move forward, the sea water was flowing, lightly impacting the torpedo, the trajectory of the torpedo was slowly deviating from the original trajectory, gradually deviating, deviating, and I saw that it was almost rubbing the hull of the submarine. , and the submarine crossed.

Inside the submarine, everyone's heart was in their throats, and they could even hear the sound of torpedoes.
