Three or four years have passed since the Feng army began to have its first submarine, and during this time, the submarine force has been obscure, even shallow gunboats can be in the news, and submarines have no news at all, and many people are not sure whether China has submarines or not.

Under this strict secrecy, the underwater muscles of the Feng army have swelled, especially after the First World War, Germany exported a large number of military jishu to the Feng army, including a full set of U-shaped submarines, and the Feng army has successively purchased shipyard equipment from Germany, and obtained a number of supporting factories in the United States and Britain and other countries.

With these as support, coupled with the ingenuity of countless Chinese workers, the Feng army produced a total of two classes of submarines, all of which were put into actual combat.

The first-stage submarine is codenamed Yaksha, the Yaksha type submarine has a surface displacement of only 254 tons, an underwater displacement of 303 tons, a surface speed of 13 knots, an underwater speed of 6.9 knots, a cruising range of 1600 nautical miles, equipped with three 533 mm torpedo tubes, carrying five torpedoes and 12 mines.

There is no doubt that the Yaksha submarine is designed and positioned as an inshore submarine, and the main area of responsibility is the Bohai Sea and the Yellow Sea region.

The small and nimble Yaksha submarine, as the name suggests, is a loyal sea guard, a patrol Yaksha, a submarine of two or three hundred tons, in the turbid waters of the Bohai Sea and the Yellow Sea, it is extremely difficult to be launched, and once targeted, the consequences are very serious, even fatal.

The second-stage submarine code name is Seawolf, and the tonnage of this class of submarines has been greatly improved, with a surface displacement of 769 tons, an underwater capacity of 871 tons, a cruising range of 8,500 nautical miles, and five torpedo tubes. A total of 14 torpedoes were carried.

During the development of the Seawolf-class submarine, some German experts joined in, and they learned from the experience of German submarines in World War I, and added four watertight compartments, which greatly improved the survivability of the submarine.

With a endurance of more than 8,000 nautical miles, the Seawolf-class submarine has fully possessed the capability of far-sea operations, and can even go out of the Pacific Ocean to cut off the maritime lifeline of the Japanese and trap this small island nation on the four narrow islands. Of course, it's not easy to do that. Dozens, if not hundreds, of submarines are needed, and now the Feng army has produced only three Seawolf-class submarines, and two more are on the slipway.

Since the Mackensen entered the South China Sea and passed through the Taiwan Strait. There are two Seawolf-class submarines quietly tracking and protecting underwater, so to speak, in order to allow the Mackensen to return to Mukden safely. Zhang Tinglan also made a bloody investment.

The commander of the Wolf One submarine was Chen Shaokuan. Although he was born in the Fujian Navy, he was not used to the clinching in the navy, especially since he had also participated in the Paris Peace Conference, and knew that this was a shijie of the jungle, and without a strong navy, he would only be bullied. The fate of being divided.

After returning to China, he caught up with Fengjun to recruit military talents everywhere, and naturally dug into Chen Shaokuan's head, he didn't want to join Fengjun. After all, in his opinion, the navy is a high jishu branch of the army, and it must be built on the basis of strong support from the state, and with a local shili, development is limited after all.

But after arriving in Mukden, he was impressed by the industrial capacity of the three eastern provinces, especially after visiting the Huludao shipyard, he completely made up his mind to join the Fengjun group. Chen Shaokuan first spent more than half a year on the Yaksha-class submarine and was familiar with submarine operations.

Because of his outstanding performance, when the Seawolf-class No. 1 boat was launched, Chen Shaokuan was appointed by Zhang Tinglan as the captain. After taking office, Chen Shaokuan also made every effort to train, and every sailor had to undergo a strict competition and assessment. Moreover, he hired some German submarine sailors and humbly learned from them the experience of naval warfare.

Just when Chen Shaokuan and the others were working their horses, the Mackensen finally returned to China, and they were also ordered to come to meet the Mackenson.

Along the way, when it was about to enter the Bohai Sea, the Japanese fleet suddenly appeared, intercepted the Mackensen, and even took it to Japan. Through the periscope, Chen Shaokuan could clearly see that the Japanese were so arrogant and excessive, that they had completely angered all the soldiers on the submarine.

They repeatedly asked for war, but Chen Shaokuan did not agree, knowing very well that his mission was to protect the Mackensen safe return to China, not to engage in naval battles with the Japanese. Even if he could sink the King Kong, the nearby port of Qingdao and Port Arthur all had Japanese fleets.

As long as the battle on this side is combined, the Japanese will immediately send a powerful fleet to intercept the Mackensen. Therefore, Chen Shaokuan had to wait until night fell, when the Japanese were the least vigilant. And he knew that the Feng army had sent submarines to carry out night mine-laying operations at the mouth of Arthur.

As long as the Japanese warships were temporarily unable to come out, the Mackensen could quickly return to the three eastern provinces with its own speed, and truly return to the hands of the Feng army safely.

Therefore, he had to wait, not only him, but also the Wolf II submarine, and the two evil wolves in the sea were staring at the Japanese warships, looking for a fighting opportunity.

Gradually, the clock pointed to ten o'clock in the evening, Chen Shaokuan felt that it was almost over, at this time, the Japanese spread the news, and when Lushun had a reaction, it would be until the early hours of the morning, which was enough for the Fengjun submarine to seal the port.

Calculating the time, Chen Shaokuan quietly ordered the submarine to float, and through the periscope, locked the largest battleship King Kong. Due to the drag of the Mackensen, the speed of the King Kong is also very slow, and two more warships have been divided to tow the Mackensen, and there is also a lack of defense around Liliang, which is at the most vulnerable time.

Chen Shaokuan locked onto the huge battleship, and at this moment, the soldiers on the entire submarine seemed to hold their breath. On the first day of enlistment, every Fengjun sailor will go to the Beiyang Navy Memorial Hall to pay respects, look at the relics of Deng Shichang, Liu Buyun and others, and listen to the stories of veterans who have experienced that naval battle.

"Sink Yoshino!" The shouts sounded in their ears, and in a trance, Chen Shaokuan and they seemed to feel that more than 20 years ago, the hot-blooded heroic spirits on this sea area came again, and they saw with their own eyes how the descendants would take revenge!

"Launch!"

Chen Shaokuan squeezed out these two words from between his teeth, and immediately three torpedoes shot towards the King Kong, Chen Shaokuan and they didn't have time to look at their own results, and after firing the torpedo, they hurriedly dived into the water.

At this time, the Japanese were sending another dinghy to check on the Mackensen, and just as they were talking and laughing, and did not care, three waves on the sea shot in.

Seeing this scene, the Japanese sailors were like being struck by lightning, and their bodies instantly became cold.

"Enemy attack, dodge!"

Most of the Japanese sailors didn't know what was happening, and even the captain of the ship, Kitaro Muta, was confused, but by the time he noticed the torpedo marks in the sea, it was too late.

Of the three torpedoes, all but one grazed the bow of the ship, and the other two all hit the middle of the Kongo. The violent explosion, like the roar of a dragon, two violent explosions, pushed the King Kong even above the water, and then fell down heavily.

The big guy of more than 30,000 tons couldn't withstand the twists and turns of this, and two black holes more than three meters large on the starboard side appeared in front of everyone, and the sea water quickly poured into them along these two holes, and the King Kong rolled in an instant.

And with the sound of steel breaking, the wound of the King Kong became bigger and bigger, and the sailors on the deck could not bear this fluctuation, and fell into the sea like dumplings. The icy sea water made them lose all their physical strength in an instant, and they could only struggle in despair.

At this time, there was a violent explosion inside the King Kong, a ball of fire, rising from the middle, blasted the deck alive, mushroom-shaped black smoke appeared in the air, the hull of the ship after this explosion, it has inevitably begun to break, into two, and quickly sank into the sea.

In less than five minutes from the time it was hit, the Kongo completely sank into the seawater, and the surrounding warships had no time to rescue it, including Mutata Kametaro, most of the people on the ship sank to the bottom of the sea with the ship.

Battleships have always been known for their strong armor and strong defensive capabilities, but Japan's Kongo is a tragedy, the warships built by the British themselves do not pay attention to defense, and this Kongo has an experimental nature, it is not a mature product at all, except for the speed is commendable, other performance is not as advanced as Shijie.

Of course, this is also related to the attack of torpedoes, if a warship takes a few shells, it will not be good, but if it hits a torpedo, at least it will hurt its muscles and bones. The reason is simple, that is, the sea water cannot be compressed like air, and after the torpedo explodes, the energy will pass through the sea water and be transmitted to the warship.

The water pressure will multiply the effect of the explosion, and the King Kong is even more unlucky that the ammunition room was hit, and a serious explosion occurred from the inside, so that the behemoth could no longer hold on, and quickly sank to the bottom of the sea, and the people on board also fed Wang Ba.

In history, the Kongo was also the only Japanese battleship sunk by a submarine in World War II, at this time the Kongo only advanced history by more than 20 years, and the one who sank this big guy also became Chinese.

Since the formation of the Japanese Combined Fleet Fleet, it has successively defeated the Beiyang Naval Division and the Russian Pacific Fleet. In two consecutive battles, one of Japan's main battleships sank, which can be called a miracle, but this miracle finally came to an end, and with the sinking of the Kongo, the aura that shrouded the Japanese Combined Fleet was finally extinguished.

The Japanese soldiers on the rest of the warships saw the burning Kongo, they were all stunned, how could such a huge sea castle be said to sink and sink, they couldn't believe it!

"It's a submarine, a submarine of the Chinese people, smash these despicable guys!" The Japanese, who were a little sober, gave orders in a hurry. But these people the Japanese did not know where the submarine had run at all, they were like headless flies, and at this very moment a periscope was already aimed at a warship again.
