944 submarines were tracked

After chatting for a while, Zhang Xiaorong stood up and said, "Okay, let's disperse, let the guitar rest and rest!" ”

Su Qin also wanted to have a good sleep, so he didn't say hello to everyone, and after a while, the light in the room dimmed, he closed his eyes, and fell asleep in a daze after a while!

I don't know when, tick-tick-tick-

A hurried voice rang out

Su Qin opened his eyes: "Won't it?" Do you want to do a drill so late? ”

He grunted inwardly and sat up slowly.

But the submariners around him had already dressed as fast as they could, and then ran out as if they were flying.

At this time.

In the command room.

The faces of the captain, deputy captain, and commissar were cold.

"Report to the captain, azimuth 020 found an unknown target." Someone reported.

The captain and co-captain looked at each other, their faces becoming more serious.

After a pause, the captain looked at the sonar room: "Sonar room, report the situation at any time." ”

"Yes!" The man in the sonar room replied.

"Navigator, plan the second route." The captain ordered.

"Yes, plan a second route."

At this time, Su Qin came to the command room with several people from the seventh group, as well as the eagle.

After a while, the commissar came over and explained in a low voice: "We are being followed, and we have just discovered an unidentified submarine following us closely. ”

"Tracking?" Su Qin and the soldiers of the seventh group looked at each other in surprise.

In fact, it is not an accident that a submarine is tracked and detected when it goes to sea, and diving and anti-submarine have always been an eternal topic in the deep sea.

Seeing that everyone was a little nervous, the political commissar smiled and was relieved: "Don't worry, it's okay, we often encounter such things, and some of them have experience in struggle." ”

Sure enough, although the faces of the captain and the deputy captain were embarrassed, they did not panic, but responded calmly and calmly, and the other soldiers also seemed to see a lot of things, just in place and step by step.

The captain said, "Not far in front of us is the junction of sea areas 7 and 9, where there is a huge sea water jump, and we plan to go there and play hide and seek with them." ”

Hydrocline?

Su Qin's heart jumped, and he immediately understood what the captain wanted to do.

Sure enough, the captain continued lightly: "We often use this seawater cline to evade anti-submarine reconnaissance by anti-submarine aircraft or other surface targets. ”

The seawater thermocline is actually very easy to understand, the sea water above is hotter, or the salinity is higher, the sea water below is colder, the sea water salinity is lower, or conversely, all kinds of different sea water meet here, so the hydrological situation is complicated, the propagation of sound in these places is very chaotic, some will be reflected, some will be refracted by refraction, and the detection of sonar will be isolated, so as the submarine and anti-submarine equipment that use sonar as the only eye once they encounter this situation, they can only catch the blind, and suddenly become blind, If you don't want to die, you can only leave quickly.

This kind of seawater cline, not to mention the navies of Xia and the United States, even the American fleet on the earth can only sigh.

It is said that during the 1996 Taiwan-Strait crisis, our military organized joint naval and air exercises in the Taiwan-Strait region to deter Baodao.

The United States sent a two-carrier fleet to flex its force in the Taiwan-Gulf Strait.

When our military's underwater forces and the US aircraft carriers were playing hide-and-seek and playing tricks, and the winners and losers had not yet been decided, the US aircraft carriers suddenly turned around and left the confrontation zone.

As is customary, the United States will never give up such a good opportunity unless its own security is threatened.

After the analysis, the biggest reason is likely to be that the US aircraft carrier encountered an underwater thermocline and discovered the phenomenon of sonar isolation, and suddenly became blind.

The blind aircraft carrier is very dangerous, and it is easy to be killed by our submarine hidden under the jump.

As powerful as the United States, it can only slip away in front of the sea water cline, not to mention others.

The sea water cline is actually relatively common, as the captain said, submarines often even use these sea water layers to lurk, or to evade anti-submarine operations.

But this has a premise, the density of the seawater thermocline must be small above and high in the lower layer, so that the submarine can gain sufficient buoyancy.

If the reverse is the opposite, the buoyancy above is large, the buoyancy below is small, this is the end, once the submarine enters such a seawater thermocline will fall down as quickly as falling off a cliff, the process of falling is very fast, the various feedback of the submarine can not keep up at all, the faster the submarine falls, the greater the pressure of the seawater, and finally, the submarine can not withstand the huge pressure, all kinds of equipment will collapse one after another, and the submarine will also be destroyed and killed.

This is "falling deep"!

The worst nightmare of submarines!

Even the United States, the most powerful country on the planet, can only end up in such a nightmare.

It is said that all the submarines that have fallen into the depth, only one submarine in China has survived, and this deed is the original form of the TV series "Sword of the Deep Sea".

It's terrible to fall deep.

The captain ordered: "Right full rudder, course, one two zero." ”

The submarine sailed forward for a short time.

The captain let out a long breath, then picked up the communicator: "Activate the battle alarm!" ”

Moment.

Tick - Tick – Tick –

A hurried voice rang out.

"Sonar room reports." The captain ordered.

"The situation in the sonar room is normal, and the enemy boat continues to track!" Sonar room report.

"Keep listening!"

"Understood!"

As one command after another was given, the 307 submarine was operating efficiently, and they first followed the normal procedure towards the sea water hopline.

At the moment of arrival, the captain ordered a large number of jammers to be fired to disrupt the enemy's interception, and taking this opportunity, the 321 submarine immediately turned around and turned to the other side.

"The whole boat is silent!" The captain ordered.

Suddenly, everyone held their breath and condensed, not even daring to breathe too much, and everyone in the submarine stopped moving, just standing quietly.

Tick! Tick! Tick!

The stopwatch on my wrist goes second after second, and every second goes very slowly, and the time that I feel like I am passing quickly on weekdays is like a snail walking at this moment.

I don't know how long it took, Su Qin felt that he was about to suffocate, and the sweat on his body wet his clothes - the temperature in the submarine was already high at the moment, around forty degrees, coupled with nervousness, sweat trickled out, and after a while, his whole body was soaked, and at this time, the captain said: "Sonar room, report the situation!" ”

"Report to the captain, the sonar signal is gone, and the enemy boat should have left!"

But the captain's brows did not loosen, and after thinking for a while, he said: "Continue to monitor, and report the situation immediately!" ”

"Understood!"

After another five or six minutes, the captain said: "The enemy boat has left, the cabins have returned to normal, and the 307 boat is advancing as planned!" ”

"Understood!"
