The Third Reich

The sonar buoy appeared in the history of World War II as a technical countermeasure to curb the Germans' growing submarine advantage. It was first invented by Britain.

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 pose a great threat. The submarines of this era are absolutely nonsense against submarine operations. Only surface ships are the main anti-submarine force. Therefore, anti-submarine helicopters have appeared in this situation.

After detecting the signal, 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. Due to the low height from the sea, it fell into the water almost after being thrown.

To deal with underwater submarines, if depth charges are used, it is quite wasteful. After all, this thing is almost entirely dependent. If it is a surface ship, the number that can be carried is more. The waste is not terrible, and it is a big deal.

However, the anti-submarine helicopter will not work. After all, it has a limited carrying capacity. Although it carries some anti-submarine deep 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 in Germany and the world's first acoustically guided 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 detecting underwater.

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

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

Even if it integrates the power of the entire 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 the enemy and the enemy, although the target data was bound to it when it was launched, the target was lost due to various reasons after the launch. When looking for it again, it is likely to attack its own warship as the target. Well, in history, this torpedo has done this more than once.

Now, with the anti-submarine helicopter, you are not afraid. The sea area where the helicopter flies must be a certain distance away from your own warship. For example, now, it is outside the maximum range of the torpedo, so you don’t have to worry about hitting your own warship by mistake. You can finally rest assured Used it.

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

"Puff!" The torpedo splashed and entered the sea. When it entered the sea, the propeller at the tail began to rotate, and the acoustic homing 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 target's signal, it starts maneuvering flight, 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 off.

"They threw something down again. This time it was louder. It might be a depth bomb." The sonarman said, and continued to listen carefully. As a result, he heard the rushing sound. It was the propeller. Turn!

"They are still torpedoes!" the sonar called anxiously: "They are coming to us!"

The enemy actually threw a torpedo! Moreover, you are at a depth of one hundred meters. Can that torpedo get under?

When he heard this, Captain Bill frowned immediately. For him, he was puzzled at this time.

Even the United States does not have self-guided torpedoes. At most, they use submarine sonars. When they are not using periscopes to search for targets, they hit torpedoes based on the data provided by sonars. They also hit the other side’s surface ships. They have never used torpedoes. Come hit the submarine.

Now, the Germans actually have torpedoes to hit their own submarines. How do they set the torpedo parameters? Generally speaking, this is simply impossible!

It is beyond their common sense.

"The torpedo is swimming towards us!" the sonarman continued.

The torpedo is still coming?

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

If it was a depth bomb, he had better leave this position so as not to be accidentally injured, but now it is a torpedo. If this torpedo can catch up with him, it can only rely on sound.

Yes, it's the sound. The opponent's torpedo can hear its own voice, and then chase it!

There is no other choice, Captain Bill can only give it a try.

The tail motor stopped, the propeller stopped stirring the water, and the humming sound disappeared. At the same time, everyone in the boat stayed in their place and made no sound.

They strictly abide by discipline. On the submarine, any negligence may put everyone in danger. Now, they are all waiting for the arrival of the last moment.

The sonar was still very nervous, listening to the sound inside the sonar, the torpedo was getting closer and closer.

"It's still approaching us," the sonarman said.

Captain Bill did not speak, he was also betting.

The current situation has exceeded their common sense. The torpedo has penetrated 100 meters below the sea and wanted to hit their submarine. Now they have remained silent and can only wait.

Turn on the electric motor to escape at this time? That would be stupid, since Captain Bill had made a decision, he would not change 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 carry out inertial navigation according to the sound just now.

The torpedo continued to move forward, and the sea was flowing, gently impacting the torpedo. The torpedo's trajectory was also slowly deviating from the original trajectory, gradually deviating and deviating, I saw it almost rubbed the submarine's hull. , And crossed the submarine.

Inside the submarine, everyone's hearts were mentioned in their throats, and they could even hear the torpedo.
