The sonar buoy appeared in World War II in history. It was a technical confrontation measure adopted to curb the Germans' increasingly huge submarine advantages. It was first invented by the UK.

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

For the fleet, the enemy's submarines pose a great threat. Submarines in this era are absolutely nonsense to submarine combat. Only surface ships are the main force of anti-submarines, so 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 dropped!

Under the short wing on the left, the t5 electric torpedo left the pylon. Because the height is very low from the sea surface, it almost fell into the water after being thrown.

It is quite wasteful to deal with underwater submarines if you use deep-water bombs. After all, this thing is almost completely confusing. If it is a surface ship, it will be more likely to carry. The waste is not scary. At worst, it can be blown up several times.

However, anti-submarine helicopters are not good. After all, they have limited capacity. Although they carry some anti-submarine deep bombs, whenever possible, they will use the latest torpedo they carry.

The t5 electric torpedo was improved on the basis of the t3 torpedo. The biggest change is its seeker, which is the first generation of Germany and the world's first acoustic self-guided torpedo, code-named g7es.

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

If you install the sonar on the torpedo, the torpedo can automatically find the direction of the sound and then attack, wouldn't it be easy to attack?

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

Even though Germany has integrated the power of the entire Europe and made investments in technology, it has developed this first generation of acoustic self-guided torpedo, which has initially achieved this goal, and it is only carried by helicopters.

Why?

Because it does not distinguish between enemies and us. Although it binds target data for it during launch, after launch, the target is lost due to various reasons. When it is searched again, it is likely to attack its warship as a target. In history, this torpedo has done this more than once.

Now, with anti-submarine helicopters, you are not afraid. The waters where the helicopter flies out must be at a certain distance from your warship. For example, now, just outside the maximum range of the torpedo, you don’t have to worry about accidentally attacking your warship, and you can finally use it with confidence.

Compared with the historical t5 torpedo, it has been improved to be able to perform anti-ship, and can also perform anti-submarine. In fact, the difference between anti-ship and anti-submarine is the problem of torpedo setting depth. When acoustic self-guided technology is used, the parameter of torpedo setting depth can be removed.

"Plop!" The torpedo splashed and entered the sea water. After it entered the sea water, the propeller at the tail began to rotate, and the first acoustic self-guiding device accurately captured the submarine at a depth of tens of meters.

The advantage of helicopters lies in their strong maneuverability. They just started to fly maneuver after capturing the target's signal, almost dropping bombs above the target's back.

At the same time, the sound of torpedo falling into the water also made the submarine underwater hear it. At this time, the opponent had just dived to a depth of 100 meters and then leveled it.

"They threw down things again. This time the sound was louder, maybe it was a deep water bomb." The sonar said, and continued to listen carefully while he actually heard the rushing sound, which was the propeller turning!

"They are still coming down torpedoes!" the sonar shouted anxiously: "He is coming to us!"

The enemy actually threw a torpedo! And it was at a depth of 100 meters. Could that torpedo be drilled down?

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

Even the United States does not have self-guided torpedoes now. At most, they use submarine sonar. When they do not use periscope to visually search targets, they use torpedoes to attack based on the data provided by the sonar. They also attack the opponent's surface ships and have never used to attack submarines.

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

It has exceeded their common sense.

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

The torpedo is still coming?

"Note, the engine stops and keeps silent." Captain Bill shouted loudly. At this moment, he could only speculate.

If the deep-water bomb came from above, he would have better leave this position to avoid being injured by accident. But now he is a torpedo. If this torpedo can catch up with him, it will only depend on sound.

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

There was no other choice, Captain Bill could only give it a try.

The motor at the tail stopped rotating, the propeller stopped stirring the water flow, and the rustling sound disappeared. At the same time, everyone in the boat stayed in their own position without making any sound.

They are strictly disciplined. On submarines, any negligence can put everyone in danger. Now, they are waiting for the last moment.

The sonar was still maintaining a high level of tension. Listening to the sound inside the sonar, the torpedo was getting closer and closer.

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

Captain Bill didn't say anything, he was also betting.

The situation now exceeded their common sense. The torpedo actually penetrated deeper than a hundred meters of sea water and wanted to attack their submarine. Now, they have remained silent and can only wait.

At this time, start the motor and escape? That's stupid. Since Captain Bill made the decision, he would not change it easily.

The t-5 torpedo is still moving forward. At this time, it can no longer hear the sound in front and disappear in an instant. Therefore, it can only navigate inertia according to the sound just now.

The torpedo continued to move forward, and the sea water was flowing, gently hitting the torpedo. The trajectory of the torpedo was also slowly deviating from its original trajectory, gradually deviating, deviating, and seeing it almost rubbing against the submarine's hull and crossing the submarine.
