Super Weapon Swap System

Active sonar!

Supporter class submarines are equipped with advanced sonar systems, including 2046 towed VLF passive array sonar, 2040 bow active passive warning sonar, 2041 hull passive array sonar and 2019 passive ranging sonar.

Looking at the models of these sonars, we can find that there are few active sonars, and most of them are passive sonars.

After all, to destroy the enemy underwater, we must first protect ourselves. To protect ourselves, we mainly rely on passive monitoring rather than active voice. As long as we make a voice, the enemy will know.

Active sonar can only be used in one aspect, that is to launch an attack!

This is like a confrontation between fighters. Before launching a missile, you must first lock the target. This active sonar plays such a role.

Passive sonar is mainly used for monitoring. No matter how high the monitoring accuracy is, it is not enough to guide the torpedo to attack. If you want to master all the parameters of the target, you need to actively transmit the past sound signal and then send it back. In this way, you can clearly find the other party's speed, orientation, depth and other information, so as to facilitate the next attack.

At the same time, the use of active sonar in submarine confrontation is also a demonstration!

With the command of Captain Lei, the sonar pressed his hand on the launch button.

"Poof, poof." two sound signals crossed the sea and headed for the target in front. Then, it hit the shell of the victor class submarine heavily. When the sound hit the shell, it made a light bang. This sound was clearly transmitted to the ears of every crew member inside.

Active sonar, the other party actually used the active sonar signal. What does this mean?

The other party must have known that his own side was following him. Since yesterday, the other party has been wandering in this sea area. In fact, it is walking around with his own side!

When he thought of this, Ivanov suddenly felt angry that these damn Han people dared to tease them. What's next? What should I do?

Your side has been discovered by the other side!

If they launch active sonar waves in the direction of their submarines according to the normal confrontation, it means that they have failed. At this time, they should float up, indicating that they admit defeat and can go.

If you fight the eagle people, you will lose if you lose, but now, if you fight the Han people, will you admit defeat in front of such a small submarine as the Han people?

Of course not!

Ivanov will not admit defeat. His eyes are full of anger. He shouted, "double cars, full speed!"

I was decelerating just now, and now the propeller is still reversing. Otherwise, my submarine will have knocked the other party away.

Now, if the other party doesn't know what's good or bad, just hit it!

The two 72 MW vm-4p PWRs at the tail are burning hotly. Eight pg-4t steam generators continuously release high-temperature and high-pressure steam into two ok-300 steam turbines, which are transformed into a powerful power of 30000 horsepower, and drive the propeller to rotate and rotate through the gtza-631 main transmission! Speed up, speed up!

The underwater Victor class, like crazy, collided with the Chinese submarine.

"They're bumping into each other!" here, the sonar shouted when he heard the other party's change.

"Attention, torpedo tubes No. 1 to No. 4, open!" shouted the captain of the mine. At this moment, his face was full of seriousness and his eyes were full of anger.

Hum, still want to go crazy? Harder than? Then compare!

"Bang, bang." there was a soft sound. In front of the bow, the four torpedo tubes were opened.

Open the torpedo launcher, that's the precursor of fire. If you dare to hit it, I dare to do it!

The sound passed quickly.

The bow rowed away the current, and the huge Victor class submarine began to accelerate. Among the clattering sound of the bow, the sound of the torpedo launcher opening the cover was still clear.

"The other party opened the torpedo launcher!"

Ivanov's mouth is ferocious. OK, how dare you do it?

"Order, open all the launch tubes for me!"

In the depths of the sea, if you really do it, it's not a big deal. Just move your hand, then run away, and then go back and refuse to admit it. You can't start a world war because of this accident, can you?

Even if it is picked up, the bear country will not be afraid. The bear country has not fought a world war. The bear country has long had the idea of unifying Europe.

"Bang, bang." just then, the sonar heard the familiar voice again. Just like just now, can he still think it was an accident?

No, since the submarine in front is prepared, the sound on the top is certainly prepared. It must be a sonar buoy!

"It is reported that we have an anti submarine aircraft overhead and are conducting sonar buoy operation," said the sonar man.

Is there an antisubmarine aircraft overhead?

Ivanov was stunned. If there was an anti submarine aircraft, it would be different.

"Hum, hum." just then, a low voice came from the boat again, stimulating the eardrums. For the submarine soldiers, of course, they knew what the sound meant.

"It's an active sonar buoy. They're positioning us!"

This is the sound from the active sonar buoy, and there is more than one. In theory, as long as there are three buoys, the accurate position of the submarine can be found.

"Pay attention to the whole boat. Dive to 300 meters." Ivanov said. As soon as his order was issued, the officer on duty shouted: "Captain, the maximum water depth here is only 300 meters!"

"Well, 290 meters, damn Han people, let's avoid these anti submarine aircraft first," Ivanov said.

If there are only ordinary submarines underwater, they can calmly play the game of underwater cats looking for mice. However, if there is an anti submarine aircraft, it will be different. At this time, the best way is to run away.

How to escape? Of course, it takes advantage of depth.

The more underwater, the more complex the hydrological environment is. Maybe there is a good shielding layer for sound, which can cover them to escape. Therefore, submarines are developing towards deep water.

Of course, this requires a high-strength shell. For example, some submarines in bear country are made of titanium alloy. They dive to a depth of kilometers. They are absolutely deep-water monsters. No weapons can reach this depth and are absolutely safe.

Vick multistage is only welded with ordinary high-strength steel. It can also easily dive to a depth of 400 meters. Now, they don't play anymore. Let's leave first.

The horizontal rudder of the bow began to extend and push the sea water. Under the reaction force of the sea water, the bow began to move downward. The huge submarine went deeper into the sea!
