Chapter 2094 Land Chapter 2289 Warrior
Therefore, from the perspective of the development of submarine equipment and technology in the world, no country's submarines can achieve fully automated emergency operations.
The human factor is always the core and key, and whether there are flexible and effective rapid response mechanisms and measures is crucial.
And the complex and changeable seawater layer, as long as it is well utilized, can also become the "green gauze tent" and "invisibility cloak" of the seabed.
Therefore, the navies of various countries attach great importance to the research of the marine environment, especially the underwater environment.Detailed and accurate ocean underwater parameters are not only conducive to the safe navigation of submarines in peacetime, but also conducive to the maneuverability and concealment of submarine operations in wartime.
Only by fully grasping the marine environment, especially the distribution and changing laws of underwater hydrophysical fields, and understanding their influence on submarine activities, can the combat effectiveness of submarines be fully utilized.
At present, due to sovereignty issues, all countries have more or less disputed territorial waters, and some countries with ulterior motives even use their advanced equipment to wantonly spy on other countries' territorial waters or airspace.
And some big countries have reached a point of insanity in the investigation of the offshore waters of other countries.
Not only will the submarine be dispatched, but some detectors will also be arranged, hidden in secret places on the seabed, so as to learn all the movements on your side.
As a navy that defends national sovereignty, it naturally has the responsibility to drive away and investigate these acts.
Therefore, Liu Junken and the others seldom stay at the base, but perform tasks underwater for a long time.This caused the situation where Song Danning couldn't even be reached by phone.
A submarine sailing silently is like a shark on the hunt, making no sound at all.And often this is the most stressful time.
You must know that if some submarines of unknown nationality sneak in, they will definitely hide in this climax, and it is difficult to detect them.
Once discovered, the distance will be very close.It's like a sniper waiting to hunt, and the prey is naturally Liu Junken's submarine.
Captain Lei Ming vigilantly observed all the information reflected by the sonar.He knows this piece of sea area like the back of his hand, and no slight abnormality can escape his eyes.
Liu Junken is half like a cheetah at this time, staring at the screen with piercing eyes. The sonar and radar are the eyes of the submarine at this moment, but they cannot see objects, but analyze them based on reflections.
Suddenly, Liu Junken's eyes narrowed, and he shouted: "Captain, something seems wrong here!"
Lei Ming glanced over, his expression was startled, and he immediately ordered: "Order, step up detection in the direction of nine o'clock!"
Following Lei Ming's order, all the detection equipment on the submarine concentrated on that abnormal point.
Soon, it became clear that this was definitely not a hidden reef or unidentified floating objects, because Lei Ming was very familiar with the nearby terrain.There are absolutely no reefs here.
As for the floating object, it is easier to judge, that thing is surging with the undercurrent, and the speed is very fast, and it will never be basically in a static state like it is now.
Originally, it was time to report to the superior, but the submarine was silent at this time.Once the radio connection is turned on, if a special situation occurs, it is easy to startle the snake and usher in an attack.
You know, people dare to sneak in because they rely on their advanced technology, but this kind of behavior is undoubtedly provocative.We have the right to take action.
And the opponent, for their own safety, may often make the possibility of firing first, especially when the opponent is evenly matched with themselves.
Once the target is sunk, they can escape and dive to the high seas. If the time comes, they will not admit it, and in the end they can only fight with public opinion.
Lei Ming naturally knew this well, and looked at Liu Junken: "What do you think should be done?"
Liu Junken's attitude was firm: "Enter a state of combat readiness and push forward, this is our territorial waters!"
There was a touch of approval on Lei Ming's face, he admired this young man very much, maybe because of this young man himself he retired.
But so what?The profession of a soldier is destined to be a profession for young people.No matter how experienced a person is, if his physical fitness is not good enough, he will lose his qualifications in the army.
"Attention all personnel, pay attention to vigilance, the submarine is moving forward at full speed!"
You can’t feel the speed when sailing underwater, just like when we are sitting in a car, what we see is always the scenery outside the car is going backwards, but we don’t know that the car is moving forward at high speed.
Lei Ming and Liu Junken stared at the screen intently, carefully observing the subtle changes inside, and nothing could escape their eyes.
The submarine turned on the maximum speed and quickly approached the target. As the distance continued to shorten, the target gradually became clear.
"Fuck! Liu Junken slammed his fist hard on the podium. At this moment, we can confirm that this is a submarine of unknown nationality!"
Their lurking position is very ingenious, just in the hidden reef in the disputed waters. This kind of position is not something a submarine that is not familiar with the terrain dares to hide. They must also have detailed sea charts.
At this time, the other party finally found them, and the inside began to panic.Although this is a disputed area, the two parties in this dispute have nothing to do with them. Their behavior today is already a provocation.
However, the captain of the opponent was obviously also a veteran, and he was very calm in the face of this situation. Facing the menacing submarine, he decisively ordered the submarine to float up, but did not order to escape.
The reason why he was so calm was because he knew that the other party was also in a period of silence at this time, and he definitely didn't get instructions from his superiors, so he didn't dare to act without authorization.
And his own submarine is obviously larger than the other side, and the strength is not comparable to the other side, he is confident that the other side will not dare to hit it.
The captain is Gordon. He is a stunning and rich professional soldier who has been cruising in territorial waters all over the world for so many years, performing various tasks.
He is a rather arrogant person, and he has never taken any country's navy seriously.In his heart, only their fleet can run amok anywhere.
The distance between the two submarines is getting closer and closer, and everyone's spirits are already highly tense.
"Start moving forward!" Just as his men were panicking, Gordon suddenly gave an unexpected order.
He wants to take a gamble, bet that his boat is strong and tough, and the other party will not dare to directly collide with him.
At this time, Lei Ming had already started to contact his superiors. Since the enemy had already discovered and made a confrontation, there was no need for him to remain silent.
Soon, they received an order not to fire first, but to drive away the opponent's submarine. The port fleet has already started to move and is rushing to support them.
There was anger in Lei Ming's eyes, although he knew that firing at this time was the best attack distance.But the overall situation is the most important. As a soldier, you still have to obey orders.
"Captain, let's hit it, since we can't fight, we can't just warn!"
Liu Junken was filled with righteous indignation, as well as all the soldiers.This is a group of people who have a high sense of mission and are ready to give everything!
"Okay, move towards the target!" Lei Ming finally gave the order!
The submarine did not slow down at all, and the enemy submarine faced the ground with full impact.Gordon's order was not carried out.
Because his subordinates are all professional soldiers with high salaries.And one of their military regulations is to allow surrender when life is seriously threatened.
How is it possible for such a soldier to sacrifice his life for the so-called belief?Therefore, no one carried out his orders.
Obviously labor and capital can live well, so why seek death?The point is not that they have never exchanged fire with the soldiers on the other side. There have been several wars in history, and they are really not afraid of death!
Looking at the earth-colored men, Gordon sighed and waved his hand: "Let's go back!"
This order was quickly executed, and the submarine became very busy.Turn around, speed up, and run away quickly.
Our submarines followed closely behind, but we had to admit that there was still a gap between the two submarines. Although they were running at full speed, the distance was getting farther and farther.
Lei Ming scolded: "Bastard, if only they found out later."
Chased all the way to the high seas, the superior ordered to return.Liu Junken's eyes were burning, but he was helpless.
Our military has always defended the territory without any provocation.So, after completing the mission, we will return home.
Gordon, who fled to the high seas, wiped his cold sweat.Although he gave the order to strike just now, he actually didn't have the courage.He was betting that the other party would not dare to confront him head-on.
But the performance of others just now has completely explained the problem.People didn't care that it really hit them.
If he really died today, the loss outweighs the gain.Fortunately, his subordinates did not obey his orders.
Fortunately, this is in the deep sea, and there is no way to capture the picture, otherwise it will be announced to the media, and everyone will be able to see them fleeing in embarrassment.
Even on the high seas, Gordon did not dare to relax in the slightest, but went straight to their bases in other countries.Only there is complete safety.
On the way back, Liu Junken frowned: "Captain, do you think they simply stopped here to collect information?"
Lei Ming looked at Liu Junken suspiciously, wondering what he wanted to express?
"I suspect that they have not only been here, they should have been to our coastal waters." Liu Junken's tone was more certain.
It was only at this time that Lei Ming suddenly realized that Liu Junken suspected that the enemy had placed a detector.
"Search the area below and around the channel with all our strength, and don't let a suspicious target go." Lei Ming decisively issued an order.
The submarine, which was returning at full speed, accelerated and began to sail slowly under the water.
Finally, at a place tens of nautical miles away from the military port, sonar and radar simultaneously discovered the target.
This is a small object, but the reflected waves are very strong.And it appears and disappears on the radar.
There is only one possibility in this case, that is, there is a stealth anti-radar device on the object.
It's just that this place is at a depth of 400 meters underwater, and there is no way for submarines to salvage this thing.
And their submarine is not equipped with mini-submarines, so there is no way to carry out underwater operations.
Looking at Liu Junken, Lei Ming said in a negotiating tone: "Report to the superiors, and let them send professionals to deal with it."
Liu Junken shook his head: "Divers can't reach this depth, and miniature submarines can't work underwater either. Let's solve it ourselves."
Lei Ming's eyes were fixed: "What are you doing? I don't allow you to mess around!"
Liu Junken smiled slightly: "Captain, have you forgotten what my nickname is?"
Liu Junken is from northern Xinjiang, which is strictly speaking a place short of water.When he first came to the fleet, he could only swim like a dog.
But since then, he has practiced his swimming and diving skills hard, and has been among the best in the fleet competition several times.
Especially diving, I once dived to the limit of what a diver can achieve with only a diving goggle.Won the title of "Water Ghost".
Lei Ming shook his head resolutely: "This is 200 meters underwater, I don't allow you to take risks!"
Liu Junken looked firm: "Then you just watch the enemy place items near our military port?"
Lei Ming was at a loss for words, but his attitude was still firm, and Liu Junken was not allowed to take risks.
At this time, the soldiers also began to gather around, asking for a fight one after another!
Looking at the resolute expressions on the young faces, Lei Ming finally sighed and said to Liu Junken:
"Put all the equipment on, the most important thing is to come back alive!"
"Yes, I promise to complete the task!" Liu Junken gave a military salute excitedly, turned around and went to prepare.
After changing into the diving suit, Liu Junken thought for a while and tied a rope around his waist.That thing was not small, so he could only tie it to his body and carry it to the sea.
There is only one way to get out of a submarine in the deep sea, and that is to climb out of the torpedo tube.That is, enter the torpedo tube first.Then open the valve outside to let the seawater pour in, and finally people go out with the seawater.
From the moment the sea water poured in, Liu Junken had already felt tremendous pressure on his body. At least the diving suit had enough support, otherwise he would have been shattered.
Even with the support of the diving suit, he still feels a little pain in his body. Anyway, he often dives, so this is not a big problem for him.
After getting out of the submarine, it was as if he had entered a huge pressure vessel, and his whole body began to ache.
Although the lights of the submarine had been turned on, the strong light was not as strong as the fireflies on the ground, and he couldn't see anything clearly two steps away.
However, because the submarine was parked on top of the suspicious object, Liu Junken found the target easily. It turned out to be a one-meter-square, spherical, tactile detector all over its body.
These tentacles are made of rubber, probably to avoid damage caused by collision with the reef.
Liu Junken wrapped the rope around the detector and tied the other end around his waist. He had to dive quickly.
Because the two oxygen cylinders carried by the diving suit can only supply oxygen for half an hour, once it exceeds, it will suffocate to death.
At this time, the submarine was also rising, and Liu Junken could use the buoyancy generated by the submarine to swim more easily.
You must know that this is a depth of 400 meters under the sea. So far, only a Japanese diver has dived to a depth of 300 meters with the help of a rope.
In fact, this place is definitely a restricted area for human beings, and Liu Junken's actions are undoubtedly making fun of his own life.
One meter, two meters, ten meters.Liu Junken's eardrums and pupils began to feel tremendous pressure.
Thank you for the reward of "drinking tea and going to adventure and book friend 96248". It is only a few votes away from the previous one. Stab him.
