It's another week, during this time, in addition to studying the movements of the army in the military department, Su Dao basically spent the rest of the time in the barracks, watching the progress of those recruits day by day, Su Dao's heart is also more confident. So far, the training of the recruits has basically come to an end, and they only need to practice more and hone in actual combat to become a real army.

Until this moment, Su Dao's tense nerves finally relaxed, if this was a sudden attack at this time, the 99th Army would only suffer greater casualties at the beginning, and the recruits in the back were familiar with the battlefield environment, plus they had seen a lot of dead people and wars, so they could naturally calm down, and then cooperate with what they had learned in the barracks to go into battle to kill the enemy.

Although it would be nice to give them another month or half a month to train, Su Dao is not an immortal, and he can control his own troops, anyway, it is almost there, if you want to fight, you can come? Although there are more recruits, Su Dao can guarantee that after a week, the surviving soldiers will be soldiers on the battlefield and know what kind of battle to fight.

Of course, since war is to kill people, no matter how well trained the soldiers are, so Su Dao does not have the luxury of letting these soldiers train for half a year or a year in peace, which is not realistic at all, nor is it in his interests, only the troops that have come over in the war are a real army.

At this moment, on the surface of the Bohai Sea, as the sky darkened, Lei Zhenhao finally ordered the submarine to surface, and at the same time turned on the submarine's generator to start charging the battery, although the submarine forces were all sent out, but in view of their clumsy technology, most of them stayed underwater to sleep during the day, except for a short time when they were ventilated, they were all in a static state at other times, only the sonar soldiers were monitoring everything around.

Waiting for the night is their real training time, anyway, the submarine stays underwater, nothing can be seen, day and night are the same, and the most important thing is that night training can cover their figure, even if the warship comes quietly, when they find the army, the army may not find them.

Standing on top of the submarine, Lei Zhenhao took a deep breath of air with a strong smell of sea, which made him particularly comfortable to arrive, and his dream for many years could finally be realized. Fortunately, Lei Zhenhao, as the captain of the submarine brigade, can have the opportunity that others do not have, that is, to stand outside the submarine and observe the situation when he is ventilating at night.

Tonight is the first time they have come to this position to train, because it is the first time to go to sea, the technology is not very proficient, so a few days ago they are only training in the Bohai Sea near Jinxi, so that they can get timely assistance after the accident, compared to their progress, the naval surface ship formation is much slower, and they are still playing on the Bohai Sea until now.

The only thing that makes them feel unfair is that when the surface ships are fine, they can go and disturb the cities controlled by the Kwantung Army around the Bohai Sea, anyway, now the warships of the Chinese army cannot enter, this is the back garden of their training, and as soon as the air force of the Eastern Army appears during the day, they immediately call for support from the air force, and at the same time try to defend with shipborne air defense weapons, but unfortunately the effect is very small, far less powerful than the air force.

Tonight, Lei Zhenhao felt that it was almost over, so after asking for instructions, he decided to take the submarine group to the Yellow Sea to go around.

"Captain, there's movement in the east." The soldiers inside the submarine yelled urgently at Lei Zhenhao.

As soon as he heard that there was movement in the east, Lei Zhenhao's spirit suddenly became full, after practicing for so long, they hadn't even launched a torpedo, and saying it really made the guys in the surface fleet laugh at them.

Lei Zhenhao immediately picked up his high-powered telescope and aimed it directly at the east, it doesn't matter if he doesn't look at it, he was startled when he saw it, with today's good weather, Lei Zhenhao saw a row of bright lights large and small in the distance, and this is by no means a light on the ground. As for whose fleet it is, he doesn't care, anyway, in these days, merchant ships rarely go here, especially at night, and this route is basically the route from this to Dalian, so Lei Zhenhao doesn't have any doubts at all.

He climbed down the ladder directly, and at the same time closed the lid on it, and shouted to the signal soldiers: "Inform all boats to sink to the periscope state and turn off the engines to stand by." ”

Sinking to the periscope state looks very clear during the day, but it is too difficult for the enemy to find it at night, even if you aim at it with a high-powered searchlight, it is estimated that you can just see a little shadow, and the formation that is sailing, most of the time it is just a big eye to sweep the water, otherwise such a long sea route, all the time to look down the sea is not tired of them?

After receiving the order, the submarines quickly began to sink, after countless exercises, now there is no problem with the sinking and sinking, and the surname of the 209 submarine can, but also makes them very excited, this began to be designed in World War II, although it was not completed, but after the improvement of World War II, the 209 has a good surname can.

Moreover, the 209 also has an advantage that the current submarine can absolutely not match, it can launch torpedoes directly from underwater, while other submarines can only be called underwater warships at most, and even when attacking, they must surface, and this time is also the most vulnerable to enemy attack.

The 209 submarine can avoid this problem very well, it is completely launched from underwater, and the other party will not be able to find your position after the fight, so if this kind of submarine attacks at night, no one can find it at all, and he has a speed of 22.5 knots underwater, and the speed of ten knots is enough for it to run 8000 nautical miles if it is shallow sailing, and if it is a little bit lower, it can only run 400 nautical miles with four knots.

But these aspects alone are enough for them to dominate the world, and even if they can't beat it, it's not a problem to escape.

"It's about ten nautical miles, and the number of targets is too large to judge the size and number of specific enemy ships." The sonar soldier quickly reported.

"Tell the boats to turn off the active sonar and engines, and the radio will be silent, and we will be free to attack when we attack. Also notify the surface fleet and let them come and have fun too. Lei Zhenhao quickly gave instructions, and it happened that the surface fleet was in the sea area between Dalian and Yantai today, and it was estimated that it would be about an hour and a half if he came at full speed.

It's training period, so they've turned on the active sonar, and if it's good, it can hear more than 10 nautical miles away, and if the environment is too bad, it can be heard within a few nautical miles, and this area, obviously, it's very difficult for the other side to detect them.

But Lei Zhenhao was still very cautious and ordered to turn off the active sonar, and only used passive sonar to listen to the distance of the target, at this moment the submarine suddenly remained silent, and the silence in the entire enclosed space was particularly terrifying, and even a needle falling on the ground could be heard very clearly, and the sweltering environment under the water made the soldiers gradually appear on their foreheads beads of sweat the size of beans.

Listening to the crackling sound of the submarine's hull, it made each of them nervous, it was the first time to participate in the war, it would be a lie to say that they were not nervous, even Lei Zhenhao, a graduate of the Royal Naval College in the United Kingdom, was also very nervous. I used to think that the submarine would be cool when it was underwater, but it wasn't until he actually got down there and turned off all the equipment that he realized that it was really fucking hot.

In addition, in order to avoid being discovered by the enemy, even the air engine was turned off, and there were no people walking around the entire submarine at this time, in this case, unless the enemy's sonar could hear the sound of a person's heart beating, it would be impossible to detect their existence at all.

Moreover, there is no case of a submarine appearing alone in Asia, and the navy thinks it is very powerful, and it will not notice it at all, and most importantly, they all know that China has no navy and no submarines.

Seeing that the ship on the opposite side still had no reaction, swaggering on the sea, Lei Zhenhao was even a little shocked, wondering if the group of people on the opposite side was a soldier? Could it really be a caravan? If this is the case, Lei Zhenhao's rash attack will be a bit too much, but soon, Lei Zhenhao dispelled the idea of wait-and-see, because he clearly saw the composition of the formation on the opposite side.

There are about forty large and small cargo ships, and there are five or six warships escorting them, and the dogskin plaster flag on it has been specially enlarged by one number, as if Lei Zhenhao will not see it. After confirming the nationality of the other party, Lei Zhenhao had no psychological pressure, and finally let him discover Xiao Yuben's fleet.

I said that I didn't even find out about my fart a few days ago, and my family went straight to the east coast of Dalian along the border of North Korea, without entering the Bohai Sea at all, and then transported the materials to Shenyang through the Shenyang-Dalian Railway. Thinking of this, Lei Zhenhao couldn't help frowning, and he didn't know how many supplies he had transported in the past few days.

When the fleet approached them about five nautical miles, Lei Zhenhao stared excitedly, although he wanted to watch it all the time, but he also knew that it was time to give up his position, and gave up the periscope to a soldier, who would calculate the distance between the two sides and the speed of the other side, etc., and then calculate the angle and time of a torpedo launch.

What they are equipped with now is not the kind of fish that can be guided, but the goal is set in advance, and the submarine will not be able to control it after it is hit, but everyone has been yy, if only they could remotely control the torpedo, if this is the case, even if they run over, they can turn around and come back, I have to say that the imagination of this group of people is really rich.

"Left Rudder Fifteen." After getting the data, Lei Zhenhao quickly issued an order based on his own experience.

"Left Rudder Fifteen." Soon one of the soldiers repeated.

"Fifteen degrees left." With the cessation of the submarine's movement, the reply order of the rudder was transmitted back from the cabin, and under normal circumstances, the submarine commander must go through three procedures after issuing an order, issuing orders, repeating them, and reporting, and only after the commander fully hears these three commands, can he know whether the submarine has been in position.

Of course, surface ships are the same, except that they can see and judge for themselves, while submarines can only know by passwords.

After the rudder was straightened, several other submarines also followed and reversed direction, and like Lei Zhenhao, they were all tracking each other's targets at any time, and no one would notice the periscope exposed on the water at night.

"Two torpedoes fired without correction!" After the opposite fleet arrived at the position that Lei Zhenhao had been optimistic about, Lei Zhenhao directly issued an order to launch two torpedoes, there are so many ships on the other side, and the two torpedoes must be launched one after another to hit one ship, and it is not impossible to hit both if you are lucky.
