Republic of China: I am a great warlord, many children, many blessings

Seeing this, Forrest Gump smiled coldly and said, "Retreat, five kilometers, and let the "Dajing" come to rescue"

"Yes, Captain."

The four U-boats disappeared again like a ghost, and instead of pursuing the Kitakami, they let another one come over.

Captain Jiro Kitakami hurriedly sent a signal to the "Oi" requesting rescue.

When the "Dajing" 4000 meters away received the news, it was stunned and confused as to how could such an accident happen suddenly? It did not dare to think too much and rushed over at full speed.

Forrest Gump watched through the periscope as the Japanese cruiser "Oi" stopped next to the cruiser "Kitakami" to rescue people.

Calmly chose the second prey "Dajing".

A-Gump said coldly: "Go up quietly, remember to get 300 meters closer"

"Yes, Captain."

The submarine stopped silently at about 270 meters.

Forrest Gump ordered: "Four torpedoes, all attack the torpedo position at the tail of the "Dajing", and fire in ten seconds."

"Yes, Captain."

As time passed, people became more nervous.

3, 2, 1!

"emission!"

Four U-boats fired their torpedoes at the same time, and a loud rumbling sound was heard.

The "Oi" was engulfed in flames, and the previous "Kitakami" was also affected.

Seeing this, Forrest Gump ordered the U-boat to surface, tauntingly.

As soon as the bow of U9 emerged from the water, it was discovered by the sharp-eyed Japanese lookout!

"Submarine, German submarine"

If you still had doubts about the reason for the sinking of the "Kitakami" just now, it is now clear!

Unfortunately, it was too late at this moment.

The "Oi" was completely destroyed, and the Kitakami warship was beyond saving. It capsized to the right after 25 minutes and finally sank to the bottom of the sea in about half an hour.

Due to the damage from the explosion and loss of power, the crew only lowered one lifeboat, and 527 officers and soldiers, including the captain, were killed.

Forrest Gump looked at the lifeboat and said mercilessly: "Send them to see God"

"Yes, Captain."

A big torpedo made a loud noise, and the whole world became quiet.

053

After doing all this, the U-boat left quietly.

The armored cruiser is a new type of warship that appeared in the world's shipbuilding industry after the mid-19th century.

This type of ship can also be called an ironclad cruiser. It has powerful firepower close to that of an ironclad ship, the speed of an ordinary cruiser, and stronger protection than an ordinary cruiser.

Simply put, it is a cruiser with protection and firepower similar to that of an ironclad ship.

However, it only imitates the ironclad ships in terms of protection. Due to the requirements for speed performance and the cost limit, the actual protection capability of this type of warship is far weaker than that of contemporary ironclad ships, making it a useless product.

In less than an hour, the two Japanese armored cruisers Beishang and Oi were reduced to ashes, 32 officers and 897 soldiers were killed, and the total tonnage exceeded 23000 tons!

In addition, the "Takachiho" sank to the bottom of the sea before, and the captain and 284 sailors were all killed.

The Japanese army lost a total of 40 officers and 1181 navy soldiers.

This was the biggest defeat suffered by the Japanese Navy since the Sino-German War.

But at this time, the Japanese Navy also received the news that the three warships Kitakami, Takachiho and Oi were all destroyed, and they were immediately furious.

Vice Admiral Kato Tomosaburo, commander-in-chief of the First Fleet of the Japanese Combined Fleet, was furious.

His First Fleet consisted of only three battleships, four cruisers (Kitakami, Takachiho, and Oi) and several destroyers. Three of them were destroyed in one go, and he was furious.

"Send all battleships to find the damn S90"

At the same time, the destroyer S90 was afraid of being attacked by Japanese warships in retaliation, so it hurriedly went south and entered Rizhao,

The S90 destroyer ran aground in Rizhao, Shandong due to running out of fuel.

The shadow of the U-boat reappears.

356. Japan begins investigating Shen Hao

The destroyer S90 lost power, and they could only stop and prepare to surrender to Beiyang, which was better than being captured by the Japanese.

Just when the S90 destroyer relaxed its vigilance, there was a loud bang.

Captain Plunnel and 61 officers and soldiers were all killed and no one was found.

It seems that there has never been an S90 destroyer in the world.

When Shen Hao learned that Forrest Gump had destroyed three Japanese cruisers, he was somewhat surprised.

After Forrest Gump dealt with the German S90 destroyer, he led the submarine back.

In Shen Hao's study, Forrest Gump gave a detailed introduction to the course and results of the naval battle.

Originally, Shen Hao intended to seize the S90 destroyer warship and take its torpedo weapons and destroyer for his own use, or destroy it if that didn't work.

But no one expected that Forrest Gump also destroyed three Japanese cruisers, two of which were armored cruisers, the Kitakami and Ooi.

Shen Hao looked at A-Gump who looked like he had made a mistake and said with a smile:

"Alright, it's destroyed.

As long as you clean up your tail, you'll be fine."

Forrest Gump patted his chest and assured, "General, don't worry about this. I guarantee with my life that no one will find any clues.

Moreover, the only ship that knew about it, the destroyer S90, had all its people on board destroyed, and no one was left alive. It had sunk to the bottom of the sea in Rizhao, and the Japanese couldn’t find it even if they wanted to.”

"That's fine, you don't need to feel any psychological burden.

Continue this state, first convert all the seized German merchant ships into training ships, and intensify the training.

There will definitely be a war between us and Japan."

Forrest Gump said confidently: "General, although we don't have as many battleships as Japan.

But the difference in the number of submarines between us and Japan is not that big. Japan has 12 and we have eight U-boats.

What's more, the main power source of our U-boats is diesel engines.

Compared with Japan's gasoline-engine submarines, they are more stable and reliable, and the Japanese are no match at all.

Tactically, the Japanese are no match either.

Our wolf pack tactics can crush them.

Even if we fight Japan now, I have the confidence that we can defeat them.

Besides, although we only have two battleships, our naval guns and ammunition are much more abundant than Japan’s, and we can completely suppress them with firepower.”

Shen Hao agreed with this point.

Shen Hao not only has naval gun shells rewarded by the system, but also armor-piercing shells.

We also bought artillery shells worth nearly 2,000 million oceans from Germany, so we could produce as many as we could. Japan didn't even have that many artillery shells.

Today’s submarines: Although they are not fast and have limited performance, they are absolutely “invincible” in an era without radar.

Because at that time, the navies of various countries did not have practical detection and anti-submarine equipment.

There is no real anti-submarine combat capability. For submarines diving underwater, they basically achieve complete "invisibility", which has always been the biggest advantage of submarines.

Of course, there is nothing a submarine can do when it encounters a battleship that is like a turtle, with thick skin and very thick armor.

After all, a submarine can only carry four or five torpedoes. If you bombard a 3-ton battleship, it's no different from tickling it.

Another thing is that current submarines also have fatal flaws.

At this time, submarines had a smaller tonnage and less storage space inside the boat, which was not conducive to long-distance voyages.

At the same time, it is also related to the relatively limited navigation capabilities.

此时日本潜艇最大的不过325吨排水量，英国在开战前最成功的潜艇为E级，排水量为水上337吨/水下807吨，有5具鱼雷发射器和1门12磅的甲板炮。

The E-class is a continuation and development of the design of the D-class submarine. The important development significance of the D-class is that the main power of the submarine has shifted from gasoline engines to more stable and reliable diesel engines.

“I heard that the British invented a K-type submarine that is even faster than a battleship on the sea.

This K-type submarine has a displacement of up to 2500 tons, a surface speed of 25 knots, an underwater speed of 9 knots, and is equipped with 8 torpedo tubes.

However, I heard that this submarine is different from other submarines that are powered by diesel engines. It is powered by steam turbines when sailing on the surface.

It has been successfully developed and launched, and it seems that it will be ready for mass production next year. "Shen Hao said;

This news was sent by Yong Jianqiu a few days ago, and it was from the German intelligence department.

Hearing this, Forrest Gump curled his lips in disdain.

He is Ernest Krause (Forrest Gump), the new captain of the Greyhound, and the wartime backdrop is World War II.

It can be said that Forrest Gump's experience exceeds that of all naval commanders in the world.

There is also a clearer understanding of submarines.

Agan said: "The surface speed is 25 knots, and the underwater speed is 9 knots. If it is true, then the surface speed of the British K-type submarine is amazing and can indeed exceed that of a battleship.

Today's battleships can only travel at a speed of around 20 knots.

The K-type submarine is powered by a steam turbine and is faster than a stable diesel engine, but it has a fatal weakness.

Although the power exceeds that of a battleship, it brings great trouble to the most important diving of the submarine.

When a K-type submarine dives, not only does it have to extinguish the boiler, but it also has to lower the chimney.

Then slowly dive into the water.

The whole process lasted 30 minutes, which was simply "silly roe deer". During this time, the destroyer could have launched a torpedo to hit it.

Even for an emergency dive of a K-type submarine, it would take 5 minutes, which seems a lot faster, but there are too many places that need to be sealed, such as the air intake and smoke exhaust ports. If the seals are not tight, it will turn into "self-sinking".

The greatest function of a submarine is that it can deliver a silent and fatal blow to some warships underwater. It is so powerful because of its strong concealment.

By reducing its noise to below 90 decibels, it can be drowned out by the roar of the ocean and avoid detection.

So, although the K-type submarine is fast, in my opinion it is far inferior to the German U-type submarine.

Moreover, the current direction of submarine development is also problematic.”

Shen Hao asked doubtfully: "What's the problem?"

Shen Hao only half understood about submarines.

Forrest Gump explained: “Today, submarines of various countries attach great importance to surface firepower.

For example, the British M-class submarine was even equipped with a 305mm naval gun, which could be called an "underwater battleship."

France has submarines equipped with twin 203mm naval guns.

They even call it a cruiser submarine because it is equipped with two 203mm naval guns!

Deck guns are quite common on submarines, what are they used for?

Do we have to give up the advantage of our submarine Sea Ghost, surface and engage in a battleship battleship battle on the water?

Of course, I also know that today's submarine technology is limited and can only sustain itself underwater for two or three days.

When a submarine sails underwater for a long time, its fuel and oxygen will be exhausted, and it will inevitably be unable to dive when it needs to dive the most due to lack of fuel.

This is why submarines now spend most of their time sailing on the surface.

Submarine is exposed on the surface for a long time. When encountering an attack from enemy surface ships, torpedoes cannot be used for defense. The only weapon is deck guns.

Although the deck gun of this type of submarine is intended to make up for the submarine's lack of firepower, it ignores the structure of the submarine.

Just remove these deck guns and it will be what a submarine should have.

I think submarines should fight and then run away, using sneak attack tactics. They will only be sitting ducks in a fight. The speed of destroyers is a nightmare for submarines.

The greatest use of wolf pack tactics is to use numbers to bully the few, fight and then run away."
