The peculiarity of Haruichi Yamada's argument lies not in how he touted the advanced and tremendous combat effectiveness of US submarines, nor in his arrogant claim that Japan would surpass other submarine powers, including China, in one fell swoop if it built submarines, but in his knowledge of submarines from the Soviet Union, Britain, France, and China.

It was sealed for several years before it was published, but it was enough to move these countries, and they all thought that they had Japanese spies in their country, which made people panic and jump......

Immediately upon his return to Japan, Haruichi Yamada was entrusted with important tasks, and at the age of 40, he became one of the last fastest-rising generals, becoming the captain of the submarine "Kawasaki".

Of course, the reason why he occupies this position is not only because of that chapter, but because he later put forward a series of ideas and tactics, such as submarine lurking tactics, scientific use of submarine simulators, giving full play to the advantages of magnetic wave detectors, etc., and his ideas have their own uniqueness.

After serving as the supreme commander of the Kawasaki submarine, he lived up to expectations and successfully completed the submarine's watch duties many times. At the beginning of this year, during the confrontation between Japan and China -- the East China Sea -- his submarine relied on his excellent command and luck to first spot two Chinese submarines under the water and launched an active attack wave with sonar. The two Chinese submarines had not yet collected any information on the submarine and had to retreat as is customary.

In peacetime, even if it is a hostile country, there is very little real fire when the submarine meets, unless you are completely sure to destroy the other side and leave no handle, do not let the other side suspect or lead the suspicion to other countries, otherwise you will not fire, will play a game of cat and mouse, collect as much as possible the performance parameters of the other party, and then go their separate ways.

If it weren't for the inability to fire, he would definitely be sure to take out at least one of China's conventional submarines and exit in its entirety.

He was commended by his superiors for his outstanding performance in this incident.

Afterwards a colleague said he congratulated him. "It's just a piece of cake to catch a Chinese conventional submarine," he said. Their noise of more than 110 decibels underwater is like a gong patrolling the streets, and it is difficult for our detection equipment not to detect them. The reason you didn't spot them was simply that I was in a little better position than you. ”

These words made those colleagues only stare dryly.

It didn't take long for the Kawasaki Chen Jun to turn the golden place into his meritorious place: a priority discovery of a Soviet submarine; Almost at the same time as a Chinese nuclear submarine spotted each other, and he easily escaped; Three times after getting rid of the tracking of the US nuclear submarine, the Americans have never figured out the identity of the submarine. As for the conventional submarines of various countries, it is even more common for them to be "caught" by him. In particular, two Australian submarines also came here to see the excitement, and one of his submarines was forced out of the water, and they had to flee back before they could figure out who their opponents were.

"Yo Xi, I'm here to make a contribution, and the more submarines you come. The greater my credit. Haruichi Yamada said triumphantly, then sat down in the chair with his back straight and looked at the man in the mirror a little narcissistically. Although this man is really a bit obscene in the eyes of others, he himself thinks that he is the most handsome.

I don't know if it's because he's narcissistic or because he's too obsessed with submarines, this guy is still single in his forties, not married, and never even in a relationship. His only hobby was to delve into submarine technology and tactics.

Except for him and a few people in the Japanese military community. No one knew that Japan had secretly cooperated militarily with the Soviet Union, the sworn enemy of Western countries, in the development of submarines. This Kawasaki submarine is the crystallization of Soviet-Japanese cooperation. It's just that the Japanese officers and soldiers believed that most of the technology of submarines was provided by the Japanese, and although the Soviets had technology, at most it was the technology of shell materials. And the instruments and meters they have improved are simply rubbish, not a grade compared to the instruments of the day, they are several orders of magnitude worse.

The Soviet Union, on the other hand, believed that the Japanese, although they provided technology, provided too little. Every time the technology is provided, it is done secretly and under the guise of a business. And every time the Soviet Union had to pay for it, the Soviet Union was depressed at the same time.

Even the reborn Guo Zhuocheng did not know about the cooperation between the Soviet Union and Japan in submarines. He only knew about the Toshiba incident and that the famous Japanese enterprise Toshiba had quietly sold the five-axis linkage machine tool restricted by Batumi to the Soviet Union for money (3.5 billion yen, equivalent to less than 18 million dollars).

In fact, the situation is far from what one might seem, and while eighteen million dollars is a lot of money, or a lot of money for some private or small businesses, it is not so unimaginable for a world-class company like Toshiba. But they dared to sell these high-grade and sophisticated equipment to the Soviet Union at the risk of offending all Western countries, obviously for other reasons, and they must have been approved, acquiesced in, and even encouraged by the Japanese government. Naturally, the Japanese military community also quietly benefited from the Soviet Union.

At the same time, Toshiba's "cooperation" with the Soviet Union must not have been an isolated case, and the Japanese government must have arranged for other enterprises to carry it out, and in the end, Toshiba was only discovered by the world.

In fact, Toshiba's discovery was also accidental, because the United States lost all traces of Soviet submarines almost overnight, and one by one they became elusive. Moreover, many countries in Western Europe have also reported that the noise of the propellers of Soviet submarines and warships has decreased significantly, and the tracking difficulty has increased. This led Western countries to wonder whether the Soviet Union had acquired any advanced technology, and it was only after 1985 that investigations began.

After the investigation, there was still a suspicion that the Japanese would reinvent Soviet submarine technology because it was less than $20 million. But suspicion is suspicion, but I can't find any evidence to prove that Japan has other purposes, and in the end I have no choice but to give up and punish Toshiba.

Except for a small number of Japanese military and political personnel, no one knew that the Kawasaki was a submarine jointly produced by Japan and the Soviet Union. Not only did this submarine evade US supervision, but the US Pacific Fleet stationed in Japan did not know about the existence of such a submarine, and even some high-ranking Japanese officers did not know about its storage. It was pitch black, without any portside number and no name, only an internal code 0007, the so-called Kawasaki was defined by Haruichi Yamada himself, because he was a Kawasaki man.

"Report! Just now our magnetic wave detector found a shadow behind it, but it quickly disappeared! We have no way of knowing if it's the instrument. Suddenly, a staff officer walked to the door of his room and said loudly.

"Directions? Distance? As soon as he heard the news, Haruichi Yamada immediately became excited, and hurriedly turned off the recording and strode towards the command tower, he wanted to return to his post as soon as possible.

The co-captain replied: "The bearing is uncertain, the distance is about two nautical miles!" ”

"Two nautical miles?" Haruichi Yamada's pace slowed down, and he glanced at the staff officer a little annoyed, and asked, "Did we notice any anomalies in this area before?" ”

"Report! No! The staff officer himself was also depressed in his heart, "This broken instrument was pressed at your request, it will be good for a while and bad for a while, how can you blame me?" ”

However, the strict military did not allow him to vent his anger, and could only tolerate it.

Haruichi Yamada thought for a few seconds, and soon issued an order: "Stop the water geological survey!" The course remains the same, the speed is two knots, and the dive is 100 meters! Scan the area several times, and if there is no anomaly for half an hour, continue with the operation just now. ”

"Yes!" The staff officer replied loudly and turned to leave.

Haru Yamada glanced at the back of the staff officer, then turned around and returned to his room, without depriving the deputy captain of the command.

When the Kawasaki slowed down, the Chinese submarine 0021 was still sitting at the bottom and did not move, everyone was silently collecting information about the Kawasaki, only Guo Zhuocheng was thinking quickly, no one knew what Guo Zhuocheng was thinking, and even Jiang Haitao doubted that there was anything worth thinking about for such a long time.

Half an hour later, the Japanese magnetic wave detector did not find anything abnormal, because the Chinese submarine sitting on the bottom had the cover of the surrounding mountains, and quietly sprayed slime for a certain period of degaussing, making this immature probe useless.

Soon, the Japanese submarine picked up speed as planned and began to surface for ventilation and recharging.

The Chinese submarine No. 0021 also floated to the bottom of the sea under the command of Jiang Haitao, and disengaged at cruising speed in the opposite direction to the Japanese submarine: today it is already a great achievement to be able to collect information about the other party's submarine and be able to determine the identity of the other party, not to mention hiding from under the nose of the other side.

Another half an hour later, when the Chinese submarine floated to 50 meters, the magnetic wave detector of the Kawasaki submarine discovered it this time, and reported it to Haruichi Yamada for the first time: "The unknown object is more than 50 meters long, about 13 meters wide up and down, and the speed of movement is about 6 knots, and its noise cannot be detected, and the distance is about 18 nautical miles." ”

"More than sixty meters? How is it possible that sonar detection cannot be detected? Is it the shadow of the magnetic wave that it just formed on the instrument? Yamada Haruichi quickly returned to the conning tower after receiving the news, and asked the deputy captain who was commanding on his behalf, frowning.

"We can't tell." The deputy captain said uncertainly, "Yamada Jun, could it be a giant whale?" ”

"How can there be such a big whale?" Haruichi Yamada wanted to loudly refute his men, but he didn't say anything. Speaking out can certainly vent his feelings, but it also shows that the quality of the magnetic wave detector he installed is not good, and the root cannot be relied on: it can't be detected at such a close distance, and it can't be really a submarine, and this instrument should really be thrown away.

As everyone knows, it is because Chinese submarines have advanced technology that they do not know.
