Chapter 1258: Was discovered again

The sun's rays can only penetrate more than ten meters of sea water, and then down, there is a dark world in the sea. At the same time, every ten meters down, it will increase the pressure of about one atmosphere, 300 meters, which is equivalent to more than 30 It's atmospheric pressure.
The shell of a nuclear submarine is under tremendous pressure. If there is any small hole, the water will flow in like a knife under high pressure, cutting everything apart. This is a pretty terrifying scene.
Now, the Victor-class submarine just dived into the icy deep sea. When the depth gauge reached 290 meters, it leveled gently.
Its whole body is constructed of AK-29 high-strength alloy steel, with a yield strength of 10 kg/cm², and a pressure-resistant shell steel plate thickness of 35 mm, which effectively increases the submarine’s dive depth.
Diving at this level is like tickling, and I don't care at all.
When it was built, it was considered to be built with titanium alloy. Although it was later abandoned because of the high cost, the submarine control rudder surface and sonar dome were all made of titanium alloy. At the same time, it is also the first submarine in Xiong that uses titanium alloy to manufacture various high-pressure pipelines.
"Attention, 3 knots, low speed sailing, the whole boat remains silent." Ivanov said.
Just now, they chased at full speed and the noise was very loud. Now, they dived into the deep sea. At the same time, coupled with low-speed navigation, the other party would definitely not be able to find themselves.
As a submarine soldier, the most important thing is to have patience. After all, anti-submarine warfare may last for several hours or even days. The confrontation between submarines and surface ships is so long.
When the order was given to keep the whole boat silent, even the conversation between the crew members could only lower the voice. At this time, the entire submarine, except for the low noise of the main circulating water pump of the nuclear reactor, and the low noise of the propeller Except for the sound, everything else disappeared.
They will disappear completely under the ocean.
"Report, the target disappeared." In the 320 submarine, Captain Lei heard the report from the sonar.
After the opponent dived, the voice became smaller and smaller. Now, when the opponent dived to the bottom of the sea, the voice was almost inaudible.
How to do?
This type of submarine produced by imported technology has a normal diving depth of 200 meters, but if it is the limit, it can be drilled to a depth of 300 meters.
It's just that this kind of danger is great, and accidents can happen at any time. As a captain, he is responsible for the lives of the soldiers on the boat.
"Report, the fleet ordered us to shut down and stand by silently." There was another voice.
As the other party dives, the challenge is suddenly even greater. At this time, your own submarine's navigation in this water area will also play a role in interference.
"Understood." Captain Lei said: "Turn off the motor, and we move with the ocean currents, release the towed array sonar, and switch to the monitoring state."
Captain Lei did not succeed. At this time, he could not influence his own anti-submarine operations. He had the most advanced fixed-wing anti-submarine aircraft, and no submarine could escape.
As for your own side, let's monitor it for now.
"Attention, release the second set of sonar buoys to expand the search distance." For the anti-submarine aircraft in the sky, their anti-submarine is still proceeding in an orderly manner.
The other party dived and hid, what should I do?
Don't worry, then throw the buoy!
Around the surrounding waters, the fan-hunting anti-submarine aircraft made a big circle, and while flying, it began to throw buoys downwards. This kind of sonar buoy, the more you throw, the higher the accuracy.
At this moment, those Seahawk anti-submarine helicopters finally arrived.
"Seahawk helicopter, Seahawk helicopter, pay attention, carry out herringbone anti-submarine operations." The commander on the hunting fan early warning aircraft shouted.
How to throw anti-submarine sonar buoys is also exquisite, especially when combined with other anti-submarine aircraft, there is a special set of procedures.
Herringbone!
The Seahawk helicopter was flying low on the sea surface. It was almost a dozen meters away from the sea surface. With the sound of puffing and puffing, sonar buoys continued to be thrown into the sea. If you look from above, you can find the sonar buoys that were thrown in. , Is similar to a herringbone.
With the increase in the number of sonar buoys, the positioning will be more accurate, but at the same time, it will also face data processing problems. At this time, the data link will begin to work!
Mass data is integrated through the data link, countless signals, through the high-speed calculation of the computer, and soon the target is clearly displayed on the screen.
Want to run, no way!
"Seahawk helicopter, pay attention, release the active sonar buoy, ready to locate!"
At this time, the hunter anti-submarine aircraft had sent the target's determined location through the data link. The Seahawk helicopter flew low and low on the sea surface, and dropped four active sonar buoys at the four corners of the target.
In the underwater, silent world, the Victor submarine is sailing slowly, and its movement is almost integrated into the background noise of the ocean. From the outside, it is almost impossible to hear.
Ivanov was standing on the bridge with a cigar in his mouth. Smoking is not allowed in the submarine, even the captain. He can only hold it in his mouth to enjoy it.
Ivanov was waiting quietly, like a sly wolf.
The sonarman has reported it many times, and buoys are constantly being dropped. It seems that the other party is searching for themselves, let them toss it!
"Boom, boom." Suddenly, it hit the boat hull like the sound of death. Everyone changed color when they heard this sound.
Who could have imagined that the Han people would have caught them again. They were sailing slowly at this depth almost close to the seabed, but they were still discovered?
This sound means to find you when hide and seek!
How to do?
The Niu people, in order to fight the South Daxiyang war, sold their fan hunting anti-submarine aircraft to Han, which must be the reason for this anti-submarine aircraft!
Ivanov was quite angry. If there were no such anti-submarine aircraft, the Han Chinese would definitely not be able to catch them. Now, what should we do?
Float?
of course not!
"Attention, sit on the bottom of the sea." With a cold expression on Ivanov's face, he gave another command to his subordinates.
The bow of the submarine slowly descended, and soon the body of the submarine was rubbed against the seabed. After hitting a group of coral reefs, finally, the huge submarine hull, like the corpse of a giant, was docked. Below, motionless.
Sitting on the bottom of the sea, the submarine captain is good at it!
