The 'Squid-class' submarine was the first submarine of the Imperial Navy that could be used in actual combat. Although, this class of submarines, judging by the data indicators of later generations, is undoubtedly extremely simple. However, in this era, it can be called an epoch-making weapon.

The Imperial Crown Prince Wu Haoxuan had great expectations for the attack of the 'Squid-class' submarines, and they would be the main force of the Imperial Navy in this naval battle. Today, the number of capital ships of the Japanese Navy is still several times that of the Imperial Navy. Even though the capital ships of the Imperial Navy are all cutting-edge battleships, it is really difficult to say whether they can defeat the Japanese Navy in the case of two fists and four hands.

If the Imperial Navy's twelve 'Squid-class' submarines were able to inflict greater damage on the Japanese Navy. And after the chaos has been caused, if the destroyer formation makes up for it, it will be enough to inflict heavy damage on the Japanese Navy. In this way, the Imperial Navy is fully capable of turning the tide in the next naval battle, or even winning it in one fell swoop.

Looking at it now, the plan of the Imperial Navy looks like an adventure no matter how you look at it. However, if the Imperial Navy did not give it a go, it would undoubtedly be impossible for the Imperial Navy to defeat the Japanese Navy. Even the Japanese dare to bet on the statecraft of the entire country, so why didn't the empire dare to bet? What's more, the empire has far more chips in its hands than the Japanese. Taking 10,000 steps back, even if the Imperial Navy loses this naval battle, it may not have a chance to start over. With the strength of the Imperial Army, it was actually able to guarantee the interests of the Empire. It is best if the Navy can win. Even if it loses, the empire can afford it.

Of course, whether it was the imperial crown prince Wu Haoxuan or the generals and officers and soldiers of the imperial navy, they did not want to lose, and everyone was eager to win. The common people of the Empire. I also hope to be able to get rid of the shame. If this battle can be won, then the empire, which is strong in both army and navy, will become a well-deserved power, and the entire Far East, the empire will be the hegemon.

'Squid-class' submarines. The displacement is 220 tons above the surface and 290 tons under water. It is 30 meters long, 3 meters wide, 4.8 meters high, and has a draft of 2.4 meters. The maximum depth of the dive is 50 meters. Propelled by two 40-horsepower diesel engines and two electric motors, the maximum speed is 10 knots at the surface and 4 knots underwater. The surface range is 500 nautical miles, and the underwater range is 30 nautical miles. It is armed with two 533 mm torpedo tubes, capable of carrying six torpedoes.

The 533 mm torpedo is a heavy torpedo. This was after the Reich acquired technology from Germany. A self-developed high-power underwater killing weapon. Of the 12 battleships of the Japanese Navy, none of them were able to withstand the attack of such heavy torpedoes. Just one hit is enough to hit it hard. If it was hit twice, it would definitely be the only one that was sunk. Not to mention the armored cruisers of the Japanese Navy, the thin armor was even more vulnerable in the face of these heavy torpedoes.

In the early morning of February 4, the imperial crown prince Wu Haoxuan, the naval commander Sa Zhenbing, and the deputy commander Admiral Cheng Biguang did not rest. Everyone is waiting for news ahead. According to the predetermined plan, the submarine forces set off in the early hours of the morning. After approaching the main force of the combined fleet of the Japanese Navy, the attack should have been between four and five o'clock in the morning. When they finished their attack, it was dawn. The lightning strike formation, which had already been prepared, would leave the port as soon as the submarine forces launched an attack, and then make up for the combined fleet of the Japanese Navy. Aggravate the blow to the combined fleet of the Japanese Navy. At this time, the main forces of the Imperial Navy, two battleships, two battlecruisers and seven light cruisers, were to leave the port for a final decisive battle with the Japanese Navy. Wipe out the main force of the Japanese Navy's combined fleet in one fell swoop and win the naval battle completely.

In Yanjing, the high-ranking officials of the imperial cabinet did not return home one by one, and all gathered at the General Staff, waiting for the results of the naval battle. They also hoped that the Imperial Navy would be able to turn the tide in this war, defeat the Japanese Navy with the weak, and gain maritime supremacy over the entire Far East. In this way, the external environment of the empire will be completely changed.

In February, the weather was already very cold. In the dark of night, visibility on the sea is very low. Twelve submarines of the submarine group of the Imperial Navy left the military port in turn and sailed into the Yellow Sea. These submarines are like big fish. The underwater range of the 'Squid-class' submarines is only 30 nautical miles, so after going to sea, these submarines do not dive, but take the way of sailing on the surface to rush to the predetermined sea area. After approaching the combined fleet of the Japanese Navy, the dive was carried out.

The lead submarine, No. 001, was the first submarine to enter service in the Imperial Navy and was also the submarine under the command of Colonel Yang Youjing, the leader of the submarine brigade. Submarines, as a new weapon of the Imperial Navy, were far less attractive than warships on the sea. In particular, the battleships or battle cruisers of the Imperial Navy were the target that every naval sailor wanted to serve. Therefore, when it comes to forming submarine forces, many people are reluctant to go.

In the end, only Colonel Yang Youjing, who was the captain of the destroyer at the time, took the initiative to ask for his life. After the submarine force was successfully formed and formed combat effectiveness, the imperial crown prince Wu Haoxuan immediately ordered Yang Youjing to be a naval colonel in this life. You must know that those officers who were at the same time as him are now at most lieutenant colonels, and most of the others are still majors. Yang Youjing's promotion shocked the other naval officers, and some even thought that a good opportunity had been missed. Only Colonel Yang Youjing himself knows how much effort he has made in order to form a submarine force and to form combat effectiveness at an early date.

"Order all boats, watch their course, and don't fall behind. Keep quiet, don't be discovered by Little Japan. Colonel Yang Youjing ordered.

Now the technology is rudimentary, and the submarine performance of the Imperial Navy is indeed very limited. If the combined fleet of the Japanese Navy were to use Port Arthur, it would be very difficult for the submarine forces of the Imperial Navy to attack them. It is a pity that the commander of the Combined Fleet of the Japanese Navy, Admiral Goro Ijiin, does not think that the Imperial Navy can threaten the Combined Fleet, nor does he think that the Imperial Navy has the courage to go to sea and fight a decisive battle with the Combined Fleet of the Japanese Navy under the current circumstances. On the other hand, in order to warn the Chinese Navy's broken fleet to go to sea again, it launched a strike on the Japanese Navy's sea transportation lines. Therefore, the United Fleet is only more than twenty nautical miles away from the port of Arthur. This distance is completely within the effective strike range of the submarines of the Imperial Navy.

Under the cover of night, the twelve submarines of the submarine group slowly moved towards the direction of the combined fleet. Although, when the submarine is sailing, it emits a certain amount of noise. But the sound of the waves on the surface of the sea, as well as the sound of the wind, muffled these noises, so that the submarines of the Imperial Navy could quietly approach the target.

By two o'clock in the morning, the submarine forces of the Imperial Navy had discovered the location of the main forces of the Combined Fleet. Although, the combined fleet has now carried out light control. However, if you look at it from a distance, you can still see the dark shadows that look like hills floating on the surface of the sea in the distance. However, by this time, the submarine forces had already encountered the destroyer detachment of the Japanese Navy. These destroyers, active on the periphery of the main forces of the fleet, search for possible enemies. Of course, these destroyers are just for show, and they do not think that the Chinese Navy will dare to go to sea to fight at this time.

Fighting at night in the dark required a high quality of sailors, and even the Japanese Navy could not give full play to the performance of the warships in night battles, let alone the Imperial Navy. What's more, the warships of the Imperial Navy had higher performance, but in night battles, these properties could not be brought into play. Therefore, as long as the commanders of the Imperial Navy have a lot of heads caught in the door, they will not choose to fight at night.

"Order the boats to dive, approach the target, and after two hours, attack." After Colonel Yang Youjing gave the order, submarine No. 001 began to dive first, and then other submarines also dived one after another, preparing to approach the main force of the Japanese Navy's combined fleet from underwater.

The maximum underwater speed of the Squid-class submarine is only 4 knots. If you want to get close to the goal, you can't do it without two hours. Fortunately, the submariners are very patient, and two hours is nothing at all for them.

The Combined Fleet of the Japanese Navy did not realize at the moment that the crisis was thinking of them coming. In the wee hours of the morning, the official man is at his tiring hour of the day. With the exception of the officers on duty, the rest of the people had already gone back to sleep in the cabins.

On the battleship Katori, the flagship of the Japanese Navy's Combined Fleet, the fleet commander, Admiral Goro Ijiin, went to rest very late. However, he was lying on the bed, tossing and turning. Perhaps it was his long-standing instinct that he always sensed that a crisis was approaching.

"What's wrong with me? No matter what, it is impossible for the people of China to turn the tables. They could only huddle in the military harbor, hiding under the protection of shore defense artillery. Tomorrow we will attack Ben Cheng, and I don't believe that the people of China will be able to continue to hide. General Ijiin Goro thought secretly. This is the battle plan that they have planned for a long time.

At this moment, not far from the battleship Katori, the sea water was surging. However, it was hidden by the darkness of the night, and the Japanese sailors did not notice it.

A rod rises from under the surface of the sea, and this is the commander of the submarine forces of the Imperial Navy looking around with a periscope. This submarine is none other than the No. 001 submarine commanded by Colonel Yang Youjing. Soon, Colonel Yang Youjing set his goal. (To be continued.) )
