Thinking of this, Haruichi Yamada changed his tone and said, "This shouldn't be a whale." But it doesn't have to be a submarine, and if it's a submarine, there's no reason why our instruments can't detect it. ”

The deputy captain glanced at his boss a little strangely, and felt that this stern boss seemed to be a little different today: why did he hesitate to speak?

Seeing the gaze of his subordinates, Haruichi Yamada scolded himself secretly, feeling that he was a bit of a mother-in-law, and he ordered loudly: "Turn around!" ”

Then he snorted coldly and said, "No matter what it is today, I will turn it out of the sea, even if it is a whale, I will use sonar to stun it." He said this, but in his heart he already decided that it was a submarine.

He also ordered: "Dive to a depth of 200 meters, sail at a speed of 8 knots, and the magnetic wave detector will be aimed at 280 to 330 degrees to scan!" Passive sonar attention monitoring! ”

Naturally, the Kawasaki's every move also fell into the eyes of the Chinese submarine officers and soldiers, who knew that the other party had discovered themselves.

Jiang Haitao, Ma Yanshu, and Guo Zhuocheng all looked at each other, their eyes full of surprise: "How did it find us?" Are we behind it? I didn't find it when I was the most dangerous just now, why did I find it when it was far away? Could it be that it has more advanced equipment on it that we don't know about? ”

The three of them nodded almost at the same time, and Jiang Haitao ordered: "Turn off the engine, take the battery drive, speed two knots, dive quickly, and go down to a depth of two hundred and forty meters!" ”

Although the nominal of the submarine is 200 meters, it can dive up to 300 meters if necessary, and the hull of the submarine can withstand a depth pressure of more than 300 meters for a short time, which is also a strong indicator of this latest submarine.

Of course, it cannot be compared with nuclear submarines that are often 300 meters, 400 meters, or even 500 meters, and nuclear submarines are too thick-skinned and rough-skinned. Because the power of the nuclear submarine is strong, plus there is almost no need to carry fuel. Enough for a submarine to have a thick hull without compromising maneuverability, not for conventional submarines, and even an AIP with hydrogen-oxygen batteries cannot be equipped with a shell that is too thick to withstand the enormous pressure of sea water caused by too deep depth.

This time, Jiang Haitao is using the thermocline and the continuous low mountains on the bottom of the sea to avoid the other party and have a face-to-face fight with the other party. The last time I succeeded, it was because I knew the other side one step ahead and deliberately avoided the other party, but now both sides have known each other's storage zài, and they are both on the same level, depending on their respective tactical levels and the equipment on the boat.

When the Chinese submarine dived. Haruichi Yamada on the Kawasaki heard a report from the detection room: "Report! Neither passive sonar nor magnetic wave detectors detected submarines and large fish. ......, the goal just now is gone! ”

At this time, the deputy captain said cautiously: "Could it be that our instrument malfunctioned just now?" Maybe it was really a whale, and now it's gone. ......, if it's a submarine, such a close distance. Our passive sonar is completely capable of receiving its noise, even from American submarines, which is not so low that we can't receive it. ”

"Your ignorance, how can whales run so fast? Diving to this depth wouldn't be a whale. Do you understand? Haruichi Yamada reprimanded sternly, because he had been paying attention to the changes in the other party.

"yes, yes, maybe they turned off the engine." The co-captain did not give up. "Could it be that there is a slight problem with the magnetic wave detector?"

Haruichi Yamada glanced at the co-captain, blinked his eyes, and then ordered: "The magnetic wave detector scans three hundred and sixty degrees, and then dives twenty meters after every three minutes." Up to a depth of three hundred meters, a speed of four knots, repeat! Then he glanced at the co-captain dissatisfiedly, turned around and said to himself: "As long as it's a conventional submarine." I can't believe I can't find you! It's a nuclear submarine, and I want you to look good! ”

"Yes! The captain is wise! "The co-captain is in a boat. Immediately passed on the order himself.

Jiang Haitao, together with Ma Yanshu and Guo Zhuocheng, was quietly discussing the unusual action of the Japanese submarine that stopped for a while and then rose. It feels like the other party is playing something famous.

"Why did it dive 20 meters and then pause for three minutes? ......," Jiang Haitao said to himself.

"But we didn't get any active sonar waves from them. What do they use to search for us? Chief of Staff Ma Yanshu also asked.

"Whether they will have new equipment, we don't know." Guo Shucheng remembered Jiang Haitao's previous words and asked.

"Well, it's possible. Our nuclear submarine was discovered by them, and it is estimated that this thing is also the ghost of this thing. But why dive 20 meters and 20 meters? Jiang Haitao nodded.

"Could it be that this thing can only detect submarines at the same depth, and if the depth difference is large, it will be difficult to detect. Zhou Tao: Is their nuclear submarine the same water layer when it was discovered? Guo asked Chengcheng. Because Guo Zhuocheng is not a professional navy or a professional submariner, it makes his thinking more open.

"By the way, I was forced out by an unknown submarine in the East China Sea at the beginning of the year with a submarine and another submarine, which is also inexplicable, as if people's detection methods are more than sonar." Ma Yanshu suddenly remembered something.

Jiang Haitao also recalled the scene of talking with Zhou Tao a few days ago, and found a clue from it. Because Zhou Tao was angry that he was discovered by a conventional submarine at the same time, and he still didn't know the nationality of the other party, he told Jiang Haitao a lot of things related to this at that time.

He recalled: "It seems that yes, it found our nuclear submarine from a seamount notch at that time, and we also found it, it was the same water layer, no more than 50 meters apart. Wait a minute, let me think about it. …… Possibly, possibly. Let's use it to get closer to it, at what depth is it now? Jiang Haitao asked, and looked at the depth table in front of him. Turning his head to Guo Shucheng and Ma Yanshu, he said: "They found us when we were on the sea at the same time as them, and now that we are diving 240 meters deep, they haven't 'seen' us. ”

"I think it's better to wait a little longer, there is a leap layer at a depth of 150 meters, and we will accelerate up when it dives to 150 meters, after all, their passive sonar is also one of the best in the world." Ma Yanshu persuaded.

"Okay, let's wait a few minutes." Jiang Haitao agreed, and while staring at the chart, he said with a smile, "I must beat the confidence of this bastard today." Their sonar performance is high, and our sonar performance is also good, who is afraid of whom, haha. ”

At this time, Guo Shucheng's lips pursed vigorously, and he said categorically: "When you are rapidly ascending, use the engine sound and the cover of the thermocline to fill the torpedo!" ”

Jiang Haitao and Ma Yanshu looked at Guo Zhuocheng dumbfounded.

Ma Yanshu blurted out, "Loading torpedoes?" Why? Once the other side hears that we are loading torpedoes, they will definitely judge that we are going to take action against them, and our submarines generally do not start a war as a last resort, not only do they need the approval of their superiors, but they also need to make sure that they do not leave any traces, and there are no warships or submarines of the other side or even a third party within 500 nautical miles around. Otherwise, we will be passive in diplomacy. The most serious thing is that once this convention is broken, once other countries do not trust our submarines, then we are likely to become the target of the other side's sneak attack, and if we really encounter being discovered, it is equivalent to being destroyed, then we will not be able to move an inch at the bottom of the sea. ”

Because no one can guarantee that their submarines will never be discovered, and no one can say that their submarines will always be superior to others, and they are not afraid of sneak attacks by others. Submarines are generally sympathetic to each other on the bottom of the sea, playing with each other, and it is commonplace to show off their IQ or equipment performance, but it is far from the point of starting a fight as soon as they meet.

Guo Zhuocheng still said: "Loading the most advanced torpedo, four rounds fired at the same time, you must ensure that you shoot it down!" ”

Then, he said sternly: "Attention, this is an order!" ”

Jiang Haitao and Ma Yanshu looked at each other, and what surprised them was not the action of "order" but the content of the order. Although Guo Zhuocheng is only the political commissar in the submarine, and according to his duties, his power is less than that of Jiang Haitao, the captain, and only when Jiang Haitao's orders are obviously wrong or detrimental to the interests of the state, the political commissar has the right to stop them, or if Jiang Haitao defects and defects to the enemy, Guo Zhuocheng has the right to shoot the other party.

But he doesn't have the power to give such a direct and active order to do something specific, only Jiang Haitao has this power.

However, Jiang Haitao, Ma Yanshu, and the operational staff officers and officers around them all knew that the stern young man in front of him had the authority to give this order. This is not only because of Guo Zhuocheng's special identity and profound background, but more importantly, they received orders from their superiors when they set off, and when they encountered serious problems, Guo Zhuocheng had the right to make a decision, and everyone, including the captain, must obey unconditionally.

Jiang Haitao, as the captain of the boat, couldn't help but ask: "Political Commissar Guo...... Director Guo, can I know the reason? Because this is too important, it is not only related to Sino-Japanese diplomacy and Sino-US relations, but also related to our navy ......."

Obviously, the change in title shows that Jiang Haitao is willing to carry out Guo Shucheng's orders, but he just wants to understand a little more clearly.

Guo Shucheng replied: "It is precisely because of the importance of the relationship, precisely because the existence of this submarine is detrimental to the progress of China's development strategy, and precisely because its survival is critical to the development of China's navy, so we must sink it." Even at the expense of ourselves. Execute the order, I'll take full responsibility if something goes wrong! ”

"Good!" Although Jiang Haitao didn't understand whether Guo Zhuocheng's words were true or false, didn't know if they were alarmist, and didn't know whether Guo Zhuocheng suddenly had such an idea in his mind because he hated the Japanese in his heart, as a soldier and did not compromise on the implementation of discipline, he immediately corrected his mentality.
