"This is the Empire's secret weapon?" The captain of the battleship Fuso, Han Masashi, looked at the oil-stained sea with a large amount of garbage floating in the distance, and couldn't help but feel sad and indignant.

When they heard that the empire still had 8 submarines and a formation of fighters on land to attack together, the commanders of each ship were also slightly relieved.

With more fighter planes in the air covering and attacking, and with the raids of those undersea killers, the Japanese felt more certain that they would win the bet.

But the truth is always unexpected.

"The little devil's submarine is like marching on a big drum!" Sonar Sergeant Li Changlin rubbed his ears and said to the commander who asked him, "Then there is no need to go out of your way to find a conspicuous target, and you still need to be on guard?" ”

The Japanese decided to use submarines to attack the main battleships in China first, so they sent all eight submarines in their hands out early to take the lead.

But apparently the Japanese overestimated their submarines.

It should be said that some of the Japanese World War II submarines had good performance, and there were many submarines of more than 3,000 tons, and even made such a strange thing as the I-400 submarine. Several ocean-going submarines have outstanding performance and can sail directly to the west coast of the United States. The most prominent thing is that the Japanese have a super advanced weapon called the oxygen torpedo. Whether it is the anti-ship Type 93 or the anti-submarine Type 95, it is much stronger than the unreliable torpedoes of the Americans at the beginning.

But on the other hand, its submarine technology is very poor. Because of material factors, the depth of Japanese submarines was generally only thirty or forty meters, which was not even a fraction of that of German submarines, and only 100-meter submarines appeared in the later period.

Also due to the weak technical foundation of the Japanese, the self-made diesel engines of Japanese submarines performed poorly, but in order to pursue the output power, the noise was extremely high, and it could not play a hidden role as a killer at all.

As long as the submarine is detected by the adversary in advance, the threat is greatly reduced, and it is often difficult to protect itself.

Before the sonar of the Huaxia ship discovered these Japanese undersea ninja turtles, in fact, their whereabouts had long been known by the Huaxia Navy.

The submarines of the Japanese were barely good in World War II. But their tactics are terrible.

Stingy, they generally did not use expensive torpedoes against merchant ships, and because their earliest opponents were continental countries such as China and Soviet Russia, they neglected the importance of breaking the war.

Moreover, the command of Japanese submarines was extremely rigid, and even a strict system of regular floating. Ignoring the flexibility of real combat.

It was their constant and regular ascent that allowed the Kirov airship to spot them early and send the news back.

The Huaxia Navy immediately activated a variety of sea search radars and sonar equipment, and even specially opened the radar monitoring system for Japan to add insurance.

With clone spies and a computer-assisted team of professional codebreakers, Japanese codes are no longer a secret. If it weren't for the training of troops, the Japanese submarine would have been locked by the airship commanded by Kirov in China and directly sunk.

But at this time, the rumbling Japanese submarine had nothing to do. The specific location and coordinates were determined by the Huaxia Navy.

The Japanese greedily divided the target into two, one team locked on the second class dreadnought battleship cruising near the sea of Saga, and the other team went to attack the second class Red Alert aircraft carrier with relatively weak armor, in a vain attempt to lock in victory with a sneak attack.

……

"The target location has been determined,......," Hashimoto, the captain of the I-58 submarine who was squinting in front of the periscope, kept reporting the data in his mouth, but suddenly found that the target of the Zhenyuan-class battleship in front of him was blocked by a larger and larger figure.

When he adjusted his focus and looked closer, he saw the busy sailors on the deck of the Keeling-class destroyer approaching at high speed preparing depth charges.

"Boom!" Before he could spread the order to be on guard to all corners of the submarine, his submarine was hit hard.

"There are submarines!" The listener's words were a step late. The underwater explosion near the tail rudder of the I-58 submarine has cracked in many places in the submarine, which is made of materials with much less performance.

"Yaga!" was quietly approached by the Huaxia submarine, which made Hashimoto Yixing scold, but at this time, he didn't care who was responsible. He needs to decide whether to rush over and attack immediately, or sneak and abscond.

The subordinates shouted in panic that the pipeline in the submarine was damaged and broken, and the sound of seawater pouring into a certain place made him quickly decide, according to the material of the Japanese submarine, in this case, diving is undoubtedly a life and death, and even without the attack of the Chinese, just the sea water can make the damaged submarine become an iron coffin that sinks to the bottom of the sea.

"Rush over and attack towards the set goal!" At this time, he no longer cared about whether to enter the encirclement of the Huaxia people, and it was all he had to do to complete the ultimate goal.

The environment of a submarine is more prone to mental breakdowns. Therefore, the requirements for submariners are stricter, and in order to support the nerves, the characteristic bushido and fanatical aura of the Japanese are more evident in the submarine force than in other naval officers and sailors.

Young Hashimoto was ready to dedicate himself, and he was sure that if he got closer, the invincible Type 95 torpedo could be fired from a distance and deal a heavy blow to the battleship.

"There are submarines approaching us quickly in the left rear!" The listener shouted hurriedly.

Thankfully, the powertrain was not hit hard. It still exerted a high speed of 6 knots underwater, but the sonar crew was surprised to find that the speed of the submarine chasing behind reached a high speed of 17 knots.

"Is this a torpedo or a submarine?" He didn't know that the XXI submarine coming from behind could increase its speed a little more, but he was already shocked by this 17-knot high speed.

At this time, the surface speed of the submarine was very fast, just like most of the Japanese Type B submarines could reach 23 knots, but they could only run up to 8 knots underwater. The difference in speed is doubled, how can it not be surprising, especially since the XXI submarine that relies on electric motors to sail is still so quiet.

But he couldn't think about it anymore, and some unpleasant sounds came from the sonar.

"There's a torpedo, be careful!" The listener was particularly familiar with the noise of the Type 95 torpedo, and could not help but exclaim.

But the XXI-class submarines, also equipped with base-made Type 95 torpedoes of absolutely reliable quality, have already delivered a surprise.

"Boom!" The Yi 58, which accelerated forward, was hit hard again.

This time, it did not escape the fate of becoming an iron coffin.

The tremendous pressure of the sea crushed the moaning of the steel skeleton of the I-58 submarine, and it completely disappeared into the silence of the seabed with regret that it had not completed the heavy patrol that damaged the Indianapolis as it had done in its previous life.

……

"Two ships sank directly, one heavy damage began to surface, and it was surrounded and annihilated by those destroyers, and one was hiding. But it can't escape, so big a movement, as long as it moves, the deaf can hear it! Hearing the report of his subordinates, Zhong Shuqian nodded and did not say anything.

This time, at his initiative, the same four Huaxia submarines practiced the submarine anti-submarine tactics of the assassins against the assassins.

In the past, Japanese submarines encountered in the East China Sea and the Yellow Sea, and although there were several successes, the tactics of attacking in such a formation were the first actual combat exercises.

The result still made him more satisfied, but he still did not dare to be complacent when he thought of the intelligence of the US submarine forces. After all, the submarine fleet of the Japanese is far worse than that of the Germans and even the Americans.

"Float! Leave the rest to the destroyers! Zhong Shuqian ordered.

Since it is a combat exercise, the guards naturally want to be safe.

Six Keeling-class destroyers escorted nearby.

However, they will not let go of this anti-submarine exercise. Since the submarine force has already started with the record of two submarines, it is natural that the surface troops should also be allowed to make a show.

The sonars of the Keeling-class destroyers have already locked onto their targets, and the depth charges have long been prepared.

Huaxia submarines hiding in the water will also be affected, and they need to stay away from the danger zone first.

During this time, the Sea of Japan Da-7 submarine, which had to float up after being hit hard, wanted to float up and fight.

However, it only had time to fire two Type 95 torpedoes before it was bombarded by the MK.32 twin 127-mm high-level dual-purpose guns of the three Keeling-class destroyers that rushed up, and it sank again.

"Boom, boom!" A group of Keeling-class destroyers were still unsatisfied, and around the place where the last Japanese submarine sank, more than a dozen depth charges smashed down in one breath as if they didn't want money.

Active sonar had already detected the approximate coordinates of the B-I submarine, which had sunk to a limit depth of 100 meters, and just when the Japanese were hoping to escape the catastrophe, the depth charges that covered their faces directly shattered their dreams.

When a large expanse of oil and garbage surfaced, the whole sea finally fell silent.

Even another battlefield more than a dozen kilometers away has long been quiet.

The four Japanese submarines that attacked the aircraft carrier over there were unfortunately encountered by the actual combat exercise of the Chinese air anti-submarine warfare, and some of the submarines were even blown up by the dense depth charges dropped by eight Catarina seaplanes and four Black Hawk helicopters before they could see their targets.

The submarine, one of Toyota's secret weapons, has been the first to finish, and the support of another fighter plane from land is equally unreliable. (To be continued.) If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. )
