Chapter 1257: Run away

Active sonar!
Supporter-class submarines are equipped with advanced sonar systems, including 2046 towed VLF passive array sonar, 2040 bow active and passive warning sonar, 2041 hull passive array sonar and 2019 passive ranging sonar.
Looking at these sonar models, you can find that there are few active sonars, and most of them are passive sonars.
After all, in order to destroy the enemy underwater, you must first protect yourself, and to protect yourself is mainly by passive monitoring instead of active vocalization. As long as you utter a sound, the enemy will know it.
Active sonar is only used in one aspect, and that is to attack!
This is like a confrontation between fighters. Before launching a missile, the target must first be locked. This active sonar plays such a role.
Passive sonar is mainly used for monitoring. No matter how high the accuracy of monitoring 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 transmit it back, so that the opponent's Speed, azimuth, depth and other information must be clearly found to facilitate the subsequent attack.
At the same time, active sonar is used in submarine confrontation, which is also a demonstration!
Following the command of Captain Lei, the sonarman pressed his hand on the launch button.
"Puff, puff." Two voice signals, passing through the sea, went towards the target in front. Then, it struck the shell of the Victor class submarine. When the sound hit the shell, it made a bang. This sound was clearly transmitted to every crew member inside. Ears.
Active sonar, the other party actually uses an active sonar signal. What does this mean?
The other party must have known that one's own side was following. Since yesterday, the other party has been wandering around in this sea area. In fact, he is taking one's own side around!
When I thought of this, Ivanov suddenly felt angrily. These Han Chinese dare to tease them. what's next? What should I do?
Your own party has been discovered by the other party!
If it is in accordance with the normal confrontation, launching active sonar waves at one's own submarine, it means that they have failed. At this time, they should float up to show that they have surrendered, and then they can leave.
If you are fighting against the Eagles, you will lose if you lose, but now, if you are against the Hans, will they give in in front of a small submarine like the Hans?
Of course not!
Ivanov will not admit defeat. His eyes are full of anger. He shouted loudly: "Two cars, full speed!"
I was decelerating just now, and the propeller is still turning backwards, otherwise, my submarine would have knocked the opponent into flight.
Now, if the other party doesn't know what is good or bad, just hit it!
The two 72 MW VM-4P pressurized water reactors at the rear are burning hot, and eight PG-4T steam generators continuously release high-temperature and high-pressure steam into two OK-300 steam turbines. Inside, transformed into a powerful power of 30,000 horsepower, through the GTZA-631 main transmission device, drive the propeller, rotate, rotate! Speed ​​up, speed up!
The Victor-class underwater, like crazy, rammed into the submarine of Han.
"They are bumping here!" Here, the sonarman shouted loudly after hearing the other party's change.
"Attention, torpedo tubes No. 1 to No. 4, turn on!" Captain Lei shouted. At this moment, his face was full of seriousness and his eyes were full of anger.
Huh, still want to go crazy? Ruthless? Then compare!
"Boom, boom." With four soft beeps, in front of the bow of the boat, all four torpedo tubes were turned on.
Turn on the torpedo tube, that is the precursor to fire, if you dare to hit it, then I dare to do it!
This voice soon passed.
The bow of the boat cut through the water, and the huge Victor-class submarine began to accelerate. Amidst the sound of water from the bow of the boat, the sound of the torpedo tube opening the lid was still clear.
"The other party opened the torpedo tube!"
Ivanov’s mouth is sullen, okay, do you still dare to do it?
"Command, turn on all the launch tubes!"
In the depths of the sea, if you really do it, it’s not a big deal. Just do it, and then run away. After you go back, you can’t admit it. You can’t start a world war because of this accident, right?
Even if it is provoked, the bear country will not be afraid. It is not that the bear country has never fought in a world war, and the bear country has long had the idea of ​​unifying Europa.
"Om, hum." At this moment, the sonarman heard the familiar voice again, the same as before. Now, can he still think it is accidental?
No, since the submarine in front is prepared, the voice overhead is of course prepared, it must be a sonar buoy!
"Report, we have an anti-submarine aircraft above our heads and we are working on sonar buoys," the sonar officer said.
Have an anti-submarine aircraft overhead?
Ivanov was taken aback. If there was an anti-submarine aircraft, it would be different.
"Om, hum." At this moment, there was a low voice again, coming from the hull of the boat, stimulating the eardrums. For the submarine soldiers, of course they knew what this sound meant.
"It's an active sonar buoy, they are 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 exact 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 given, the officer on duty shouted: "Captain, the maximum water depth here is only 300 meters!"
"Well, two hundred and ninety meters, Han Chinese, let's avoid these anti-submarine aircraft first." Ivanov said.
If there are only ordinary submarines underwater, they can calmly play the game of cat-and-mouse underwater, but if there are anti-submarine aircraft, it is different. At this time, the best way is to escape.
How to escape? Of course it is to use the advantage of depth.
The more underwater, the more complicated the hydrological environment, and maybe there is a sound shielding layer that can protect them from escape. Therefore, the submarine develops towards deep water.
Of course, this requires a high-strength shell. Some submarines like Xiong’s country are made of titanium alloys. They can dive to a depth of more than one thousand meters. They are absolutely deep-water monsters. This depth cannot be reached by any weapon. It is absolutely safe.
The Victor grade is just welded with ordinary high-strength steel, and it can easily dive to a depth of 400 meters. Now, they don't play anymore, and they will leave first.
The horizontal rudder of the bow of the boat began to stretch out, pushing the seawater, and under the reaction force of the seawater, the bow of the boat began to move downwards, and the huge submarine got into the deeper water!
