Jeju Island is located in the East China Sea, at the southern end of the Choshin Peninsula, and is also the gateway island of the Choshin Peninsula.

Jeju Island is basically the only way to go from the Japanese mainland to the northeast of China.

This has also become an area where submarine forces focus on tracking.

The First Submarine Brigade has been active in this area for a period of time.

It sank Japanese warships and merchant ships with a tonnage of more than 10,000 tons.

This is also because the Combined Fleet attaches great importance to it.

In the subsequent sea transportation, a large number of escort fleets were equipped, and a centralized escort method was adopted.

This also made it difficult for the First Submarine Brigade to take action.

And today, another large fleet set off from the Sasebo Port in Japan. Along the way, this large fleet was mighty, and after joining the escort fleet in the open sea.

It came directly to Jeju Island.

This fleet consists of 6 10,000-20,000-ton transport ships, 8 3,000-5,000-ton transport ships, and 11 bulk carriers below 3,000 tons.

These transport ships and bulk carriers mainly transport various weapons and ammunition, food, and supplies.

In addition, there are many coastal defense guns and mortars with a caliber of more than 200 mm.

The 8 troop transport ships are loaded with the 13th Division of the Japanese Army.

Before the 1920s, the Japanese army had a total of 21 permanent divisions.

But after the end of World War I, the Japanese army carried out disarmament.

Four permanent divisions were disbanded, namely the 13th, 15th, 17th, and 18th divisions.

The Kwantung Army was almost annihilated, and the number of permanent divisions annihilated reached 5.

This made their manpower insufficient.

So Emperor Hirohito decided to re-activate the four disbanded divisions.

And reorganize the five annihilated divisions.

However, these reorganized divisions were directly downgraded to become three-unit divisions.

That is, the so-called Type B division.

If you want to regain the position of the permanent division, you can only fight back.

This can also be regarded as a spur to these divisions.

In addition to these divisions.

The top leaders of the Japanese Army also decided to expand the army.

At least 10 new Type B divisions will be formed.

To deal with the changes that may occur next.

This incident refers to the Chaomo Peninsula.

These Type B divisions started with the 22nd Division.

In addition, the Army General Staff Headquarters also decided to cooperate with a number of military industrial enterprises to study anti-tank weapons, anti-aircraft weapons, tanks, etc. to strengthen the anti-tank and anti-aircraft capabilities of the field troops.

At least in this way, when facing Chinese tanks, they will not be helpless due to the lack of anti-tank weapons.

Soon Mitsubishi Heavy Industries came up with a tank defense gun.

It is a replica of the German 37mm anti-tank gun.

Since this year is 1933, it is also named the Type 91 37mm tank defense gun.

At present, this tank defense gun has been mass-produced.

More than 200 Type 91 tank defense guns were installed in this fleet.

The Japanese army is still very good at summarizing experience in war.

However, their scientific research capabilities are not strong, and their industry is also weak, especially resources limit their development.

So their weapons all have a sense of pettiness.

For example, the 37mm tank defense gun.

It is a joke to use it to fight the Guardian main battle tank.

Such a large-scale fleet is also loaded with the strength of an entire division.

So the escort formation sent out is also quite luxurious.

The flagship is the Hiei battleship, the second ship of the Kongo battleship.

The sinking of the Kongo battleship also made the soldiers on the Hiei battleship very angry.

Such a powerful battleship was actually sunk by a small submarine.

It is simply a disgrace to the Kongo-class battleship.

In addition to the Hiei, there are the Myoko heavy cruiser and the Haguro heavy cruiser.

Both of these heavy cruisers belong to the Myoko-class heavy cruisers.

Although they are treaty-class heavy cruisers, they were both in service during the 26th-29th years.

The ships are still very new and their combat effectiveness is not weak.

These ships have especially strengthened their anti-submarine capabilities.

Some anti-submarine technology has also been introduced from Germany and England. The anti-submarine sonar has been upgraded.

The remaining are 2 light cruisers and 9 destroyers.

The scale of the escort fleet is still very large.

This is also what the Combined Fleet wants to show its presence.

Go to the Yellow Sea to show off your power.

Otherwise, there is no need to send the Hiei battleship.

After completing this mission.

The Hiei battleship will also undergo a second modernization upgrade.

How could such a large fleet not be discovered by the Akula-class submarine?

An Akula submarine that was performing a silent navigation mission discovered this fleet with sonar.

"Oh my god, it's a big fish."

The sonar operator heard the noise coming from the headset.

He stared at the ripples on the display in front of him and exclaimed in a low voice.

This also attracted the attention of the boat captain Jiang Bo.

He came to the sonar room and looked at the fluctuations on the display. His eyes fixed

"Captain, a large fleet of more than 30 ships has been found.

I also found a Japanese battleship, which should be a Kongo-class battleship based on the sound pattern comparison.

Some other ships are sailing very slowly at only 10 knots, which should be merchant ships.

I speculate that this should be a large fleet and escort fleet."

The sonar operator is the eyes and ears of the submarine.

He can hear and see a lot of information through the changes in sound.

His speculation is also very accurate.

Such a big fish is not something that a submarine can swallow.

"Use sonar communication to contact nearby submarines and ask them to transmit this information back.

Increase the speed, hang behind them, and keep an eye on them."

The captain made a decision immediately.

They were too close to the Japanese fleet.

They currently have only three ways to communicate with the outside world.

The first is to release a towed communication buoy.

The second is to surface directly and use a long-wave radio to contact the land communication station.

The third is to use sonar communication to contact nearby submarines and ask them to pass on the information.

The first two will undoubtedly expose their position.

So only the third option can be chosen.

Currently, more than 30 submarines are distributed in the Yellow Sea and the northern waters of the East China Sea.

Therefore, it is easy to contact nearby submarines.

This information was also sent to the submarine headquarters. Xiang

Haiyang attached great importance to this.

And immediately informed Jiang Fan of the news.

What else is there to say?

"Mobilize nearby submarines to form a wolf pack and launch an attack on the Japanese fleet.

Such a large fleet must be carrying a lot of things.

Immediately contact the Navy, form a joint operations command, and swallow them up."

Faced with Jiang Fan's highest instructions, Xiang Haiyang immediately began to execute.

The joint operations command was established in Jinxi.

At the same time, the land communication station also used long-wave radio stations to unilaterally contact submarines distributed in the Yellow Sea and the East China Sea.

Let them rush to the designated waters as quickly as possible.

At the same time, the Navy also sent patrol planes and reconnaissance planes to conduct detailed reconnaissance of the Japanese fleet.

A few hours later, more detailed intelligence about the fleet was obtained.

"Oh, the scale is really not small."

Seeing the full picture of this fleet, Xiang Haiyang's eyes lit up.

This time he really encountered a big fish.

Then he said to Zhao Yan, the commander of the Red Alert Corps' naval aviation department:"Commander Zhao, I'm afraid the Navy and the Navy will have to work together this time."

Zhao Yan's face was serious, and he said in a deep voice:"Don't worry, Commander Xiang, our Navy will definitely go all out and leave no chance for the Japanese army."

Now the Red Alert Corps has no surface ships in the Northeast.

And then they are facing the Combined Fleet, the world's third fleet.

The pressure on coastal defense is very great.

Jiang Fan also attaches great importance to this.

From Shanhaiguan to Yingkou, a total of 8 artillery positions and 32 coastal defense artillery versions of the Red Alert giant cannons have been deployed.

In addition to coastal defense artillery, the Navy has also become a major branch of the military.

Coastal defense mainly depends on these Navy fighters.

So their scale is also expanding rapidly.

The main aircraft types of the Navy are the MiG-10 carrier-based version and the Invader fighter-bomber carrier-based version.

The number of these two fighters has exceeded two hundred.

In addition, it is also equipped with Two squadrons attacked 60 Naval Aviation versions of the peacekeeping heavy bombers.

There were also more than 40 other types of fighters.

The reason why the Naval Aviation was equipped with horizontal bombers was mainly for a weapon, and this heavy horizontal bomber was also an excellent fighter platform for air-dropping mines. (To read the exciting novel, go to Faloo Novel Network!)

This weapon is the Fritz X-ship missile, which was short-lived in World War II.

This anti-ship missile has a total weight of 1.5 tons and a warhead of 290 kg.

It has a Strasbourg signal receiver installed in the box-shaped tail wing.

There are also two gyroscopes for direction control.

It can be fine-tuned in flight.[]

Its tail is also equipped with a pyrotechnic trail.

The operator can visually observe the flight direction of the bomb on the bomber and make small adjustments through the joystick.

Therefore, the naval version modified the bomber, and the reinforced glass used in the front has a good downward field of view, which is convenient for the operator to operate.

This Fritz X ship missile was used in actual combat during World War II.

Compared with bombs, it has a very high hit rate.

In a circular area within a range of 30 meters, the hit rate is as high as 92%.

Large ships are more than 100 meters long and 10 to 20 meters wide.

So the hit rate is more than 60% at least.

Of course, this is in good weather.

Its appearance made the Allies frightened for a long time.

Until later, the Allies developed a special jamming device.

The Fritz X ship missile lost its effect.

But it laid the foundation for the development of guided anti-ship weapons.

The Peacekeeping heavy bomber can carry 6 Fritz X anti-ship missiles at a time.

And the safe bombing altitude is between 3000-5000 meters.

Since the Fritz X-ship missile has a maximum range of 5 kilometers.

The air defense capability of Japanese warships is also weak.

So the combat environment is still quite good.

This time, the Navy will be divided into two batches, and a total of 60 peacekeeping bombers will be dispatched.

Last time, the Navy didn't even get a bite of soup.

This time, it must be more competitive.

What's more, in addition to the peacekeeping bombers.

The Navy also has the Invader fighter-bomber.

It can carry two 1-ton aerial torpedoes at a time.

This aerial torpedo can be dropped at a speed of more than 700 kilometers per hour and an altitude of about 1,000 meters.

The survivability is greatly improved.

This time the navy can be said to have played all its trump cards for this large fleet.

This plan is also named the debt collection plan.

This debt refers to the blood debt of the Sino-Japanese War of 1894.

After more than 30 submarines received the order, 21 submarines immediately went to the designated sea area.

The rest of the submarines were too far away, and they couldn't catch up at all.

21 submarines are basically enough.

This debt collection plan will be mainly based on naval aviation, supplemented by submarine forces.

The naval aviation force will launch the first attack.

Disrupt their formation.

Then the submarine force will take advantage of the chaos to rush in and start killing all around.

The Japanese fleet was very cautious.

The Kongo battleship was carried by the submarine, so how could they take it lightly?

A dozen destroyers and light cruisers on the periphery opened up an anti-submarine network.

The battleships and two heavy cruisers are located in the middle layer.

The middle is naturally the fleet.

There are the Hiei battleship and two Myoho-class heavy cruisers.

This naval escort formation alone is enough to roam Asia without any rivals.

There is not even a battleship of another country in Asia.

So there is nothing wrong with this escort fleet being able to roam Asia.

"Report to the commander-in-chief, all the seaplanes we sent to the front have lost contact."

After sailing for more than a day, they finally arrived in the waters near Seoul.

It was about 120 nautical miles away from Seoul and about 200 nautical miles away from Port Arthur.

Colonel Katsura Taro, commander of the escort fleet and captain of the battleship Hiei, was shocked when he heard this.

If a seaplane lost contact, it could be explained by radio failure or plane crash.

But several seaplanes were lost in a short period of time.��

And there was no time to even send a radio.

There is only one explanation.

"The Chinese planes are coming. Order the entire fleet to form a circular air defense circle to protect all merchant ships."

At this moment, his face became more and more solemn.

Although he was a battleship captain, he admired Sanben Wuliu very much. He also felt that aircraft carriers were the future of the sea.

Fighter planes will gradually occupy a dominant position as their performance improves.

Although he didn't know how many planes were coming this time.

But he was very clear about the performance of the fighter planes of the Northeast China Forces, which definitely exceeded theirs.

Otherwise, the Army Aviation would not have suffered heavy losses repeatedly.

More than 100 fighter planes were lost at one time some time ago.

The Navy Aviation was also a little depressed.

I didn't expect the little devils to be so cautious and sent seaplanes to conduct reconnaissance.

I had no choice but to choose to shoot down these seaplanes.

Doing so would undoubtedly expose their existence.

But it didn't matter.

Under the cover of more than 58 MiG fighters.

30 peacekeeping bombers formed several formations, flying in the airspace of 3000-4000 meters.

Soon they saw the Japanese fleet changing its formation on the sea in the distance.

And their appearance was also discovered by the vigilant Japanese army.

When seeing the huge fleet of incoming aircraft.

Colonel Katsura Taro couldn't help but take a breath of cold air.

Especially the 30 peacekeeping heavy bombers, which made his eyes jump.

But then he breathed a sigh of relief.

Fortunately, the ones coming were horizontal bombers with limited hit accuracy.

It just looked bluffing.

But it can't be underestimated.

The Japanese fleet was ready.

30 bombers formed three 10-plane formations, encircling the Japanese fleet from the front, left wing, and right wing.

The 58 escort fighters roared towards the fleet.

Their target was not the fleet, but to attract firepower.

To give the bombers a chance to attack.

After all, if you want a high hit rate, the bombers need to maintain a stable flying posture.

Sure enough, seeing the MiG fleet rushing over.

The Japanese fleet opened fire decisively.

Dense anti-aircraft shells continued to rise.

However, the MiG fighters were very fast and did not attack.

The Japanese anti-aircraft artillery had no effect on them.

After the submarine unit's sonar received the sound, it knew that the battle had begun.

The lurking submarine unit launched an attack in advance.

It also disrupted the rhythm of the battle to a certain extent.

But it didn't matter.

Torpedoes attacked the Japanese outer escort destroyers and light cruisers from multiple directions.

"boom.....boom.......boom......."

Several destroyers were hit by torpedoes, raising water columns. They quickly sank into the sea.

This sudden change stunned both the Navy and the Japanese.

The Navy was very surprised why the submarine launched an attack in advance.

The Japanese were horrified. They didn't expect that there were submarines lurking in the surrounding area.

"Damn it, it's a Chinese submarine, damn it, damn it."

Katsura Taro was really panicking at this moment.

It seemed that he had been targeted for a long time.��
