Obviously, Jiang Haitao knew that Guo Zhuocheng didn't like to do any mobilization, so he glanced at Guo Zhuocheng before finishing his speech, and saw that Guo Zhuocheng had no intention of speaking, so he ordered to get on the boat: Now is not a war period, it doesn't matter if you don't do mobilization, anyway, discipline has been emphasized countless times.

The massive submarine slowly moved away from the dock and smoothly headed towards the lifting pool.

Although its speed was slow, its massive body caused ripples on the surface of the calm water.

Not far from the pier, the submarine began to sink as a whole, and the water level of the berth was raised by several inches. After witnessing it quietly sink to the bottom, the shore support personnel withdrew their gaze and concentrated on completing their full-time work.

With the help of the auxiliary positioning system in the lifting pool, the submarine has been slowly sinking in the same direction, and the hull makes a slight "click" sound due to the change in water pressure, and the soldiers who have only been on the submarine a few times feel a little frightened by this sound, while the veterans seem to hear the laughter of their long-lost friends and listen comfortably.

Jiang Haitao stared at the dashboard in front of him with all his body, watching the depth gauge change: "...... Five-meter ...... 10 meters ...... Twenty meters ...... Fifty meters...... 100 meters...... One hundred and fifty meters ......"

"Stop diving!" Jiang Haitao saw a green light on the panel, and immediately commanded loudly.

Someone below immediately repeated Jiang Haitao's order: "Stop diving!" ”

Although the informatization process of the submarine is not high, the basic information transmission system still exists. In fact, the submarine does have a simple information processing system, and the captain's instructions will be transmitted to the various execution positions through the system, and the execution will be fed back to the command station without him shouting.

But Jiang Haitao, who was born as a submarine commander, was accustomed to shouting like this, and the people below answered loudly. I think it's imposing and humane. It is easier to close the distance between the commander and the executor. Of course, the command transmission method of the information processing system is more scientific and faster, and the sound is lowered, which is more conducive to secrecy in wartime.

It's not wartime, isn't it?

Therefore, Jiang Haitao is still willing to use the majestic oral method of giving orders when there is no hostile situation, and use "high technology" at other times. Do you think this is at home, and now you can not take the opportunity to be awe-inspiring? As soon as I got out of this cave, I could only command silently, which was so unpleasant.

The submarine shook slightly, and the occupants felt that the submarine had stopped sinking. The feeling that the person is falling slightly due to inertia.

Jiang Haitao glanced at the depth gauge, nodded with satisfaction, glanced at the deputy captain next to him, and the other party also smiled and nodded: The submarine is exactly stopped at a depth of one hundred and eighty meters, and the center of the submarine center line and the tunnel almost coincide. It seems that everyone's training effect is getting better and better, but it will not be so consistent before, and it will always be a few meters away from the goal.

Jiang Haitao issued another loud order: "Apply for the cave to open the door!" Report the situation outside the cave again! ”

Soon the situation was transmitted to the command station through the guò chain of command and verbally:

"The steel door on the first floor of the cave has been opened! You can enter the first level of the gate stack! ”

"The situation outside the cave is normal!"

A full set of anti-submarine early warning detection systems produced by China and anti-aircraft early warning radars imported from Britain are installed outside the cavern, which together provide a safe external access environment for submarines. It's just that the electromagnetic waves leaked from these systems are attributed to the Night Pearl Island's own protection system. It has already communicated with the American side and is part of the "legal" defense system of this island.

The submarine passed through the first steel gate and entered the first stage of the lock stack, after which the first steel gate closed. Wait for the second steel door to open. Soon, the second-tier steel gate opened, and the submarine slowly drove into the second-tier lock. Then the second steel door closes and the third steel door opens. The submarine entered the cave and entered the Pacific Ocean.

The reason why the submarine is so troublesome to go out once is purely for safety reasons, but also to prevent the cave from being damaged by enemy torpedoes or depth charges after being discovered.

Jiang Haitao handed over the command to Chief of Staff Ma Yanshu. And he himself whispered the relevant number to Guo Zhuocheng next to him.

Seriously, Guo Zhuocheng felt a little weak in his heart at this time. It's not that he's worried. It was because he was accustomed to controlling his own destiny, not a submariner, and he felt that he could not control his own destiny at this time, especially when he heard the terrible sound of the submarine's hull due to the high pressure of the seawater, he didn't know if something would happen to the submarine.

Last time, he accompanied the commander of the navy into the submarine and also went through the submarine's dive, but that time, because the commander of the navy and the commander of the South China Sea Fleet were on the submarine, the depth of the submarine was far from so deep, and the shell of the submarine did not make such a rattling sound as it is now. After all, there are high-ranking officials above, and as a submarine commander, he does not dare to take risks, and if something happens, it will be an earth-shattering event, and no one can afford this responsibility, so he can only be an example.

At this time, a green light lit up on the dial in front of Jiang Haitao, and he whispered to Guo Zhuocheng: "This is the sonar soldier telling us that our submarine has entered the predetermined position and can start to enter the ocean with confidence." ”

At this time, Chief of Staff Ma Yanshu ordered loudly: "The bow of the boat is ten degrees, the course is thirty-three degrees, the speed is eight knots, and the depth is one hundred meters!" Start your training according to a predetermined training syllabus. ”

With a muffled sound, the speed of the submarine did not feel very strong, but the angle of tilt when it floated still made Guo Zhuocheng feel obvious, prompting it to move up.

It wasn't until it had risen to a depth of 100 meters that it slowly flattened its massive body.

When the submarine was leveled and moved forward at a constant speed, Guo Zhuocheng's heart was much quieter, and his heart was soon steady.

Because his expression has almost never changed, others, including Jiang Haitao, thought that Guo Zhuocheng had no false heart, and saw that the faces of individual officers and soldiers around him were not normal-the previous submarines had not dived so deep, and they couldn't help but secretly admire Guo Zhuocheng's courage, they didn't know that they overestimated Guo Zhuocheng.

Under the command of Ma Yanshu, the submarine not only carried out training in various subjects, but also carried out sonar detection, and experts constantly used the results of sonar detection to depict the seabed and draw a more accurate map of the sea.

When no one gave an order, it was very quiet in the submarine, only the sound of the electric motor driving the propeller, but it was not loud, it was similar to the sound of a bee buzzing, and it sounded in the ears smoothly and rhythmically. He/she is like a giant whale moving slowly and cautiously forward, its invisible tentacles—sonar—caressing the surrounding qiē carefully: the sea, the mountains, the seabed, the fish......

Numbers that the layman does not understand are also recorded on sea drawings by experts: longitude, latitude, sea depth, salinity, current direction, current velocity, fish population, background noise, topographic changes, ......

When the submarine stayed under the surface of the sea for a period of time, the submarine slowly surfaced, on the one hand, the exhaust gas in the submarine was discharged, while charging the battery, and at the same time, the oxygen in the outside air was collected with precision instruments, and pumped into the oxygen storage tank with a high-pressure air pump for use in the next dive.

The submarine uses the technology of injecting oxygen into the exhaust gases of the engines under the surface of the sea, simulating the composition of the atmosphere in nature to maintain the operation of the engines, and the amount of oxygen in the oxygen tanks must be maintained.

……

In the first few days, Guo Zhuocheng, who stayed on the submarine, still felt that he had a good taste, constantly learned about the knowledge of the submarine, and constantly thought about how to improve the information level of the submarine; when he had nothing to do, he chatted with the officers and men who were off duty and did their ideological work, so as to urge them to stay on the submarine with peace of mind and work in good spirits.

However, Guo Zhuocheng soon found that his actions were in vain, no, it should be said that it was a superfluous move, because these officers and soldiers did not need him to do ideological work, they were all elites selected by the army at all levels, and they all had extremely high political and ideological awareness, and their working environment on this submarine was much better than before, and everyone was very happy, and they were all eager to do everything, and they were all models of discipline, and they were desperately trying to learn new knowledge. Seriously, they are still worried that they will not be able to be driven back here, and it will be a big loss, not only will they have a bad face, let their comrades-in-arms see jokes, but they will also have to go back to the old submarine that is small and low-tech.

In other words, Guo Zhuocheng's political commissar duties are almost not fulfilled, except for symbolically supervising the implementation of the training syllabus, the rest of the time is a little difficult to pass. Later, he was a little bored, and finally found a way to kill his time: learn Japanese and Russian from the people on the submarine. At the same time, he also helps others learn English.

Submariners, especially officers, are highly skilled personnel who generally have mastered a foreign language. Because most of China's submarines were Soviet-style submarines, and there were many people who learned Russian at that time, more than half of the officers on the submarines could speak Russian fluently, and a quarter of the soldiers could also speak some.

Because the submarine has been in the sea for a long time, it is likely to need rescue because of danger, and it may also have to rescue the ships and seafarers of allies, and the submarine is also deliberately equipped with some people who can understand English, French, German, Japanese, and other languages.

Under Guo Zhuocheng's organization, all the officers and men who were off duty joined this kind of spontaneous language training class, and they became teachers and students at one time. Because there is nothing to do and everyone is enclosed in a small space, the benefits of learning are high. In just one week at sea, Guo learned to speak a lot of Japanese and a lot of Russian, although he couldn't write much, but it was not difficult to have some daily conversations.

Guo Zhuocheng laughed at himself in private: "Hehe, I can't imagine that I can force two languages in a submarine." ”
