What happened to the noodles, Du Xinghua could only guess. 【Reading.com】

It was not until the end of the war that Du Xinghua knew that when the "Thorn Dolphin" evaded the torpedo attack, the "Tiger Dolphin" that accompanied the operation did not leave and was always moving nearby. At that time, in addition to the anti-submarine patrol aircraft attacking the "Thornfish", 2 anti-submarine destroyers rushed over. In order to cover the "Thorn Dolphin", the "Tiger Dolphin" ventured to attack the anti-submarine destroyers of the Japanese Navy, sinking 2 Japanese battleships with torpedoes. It's just that the luck of the "Tiger Dolphin" was not as good as that of the "Thorn Dolphin", and when attacking the Japanese battleship, the second group of Japanese anti-submarine patrol planes arrived, found and sank the "Tiger Dolphin" with 3 aviation anti-submarine torpedoes.

Because the "Tiger Dolphin" never returned to the base, the Republic Navy could only include the "Tiger Dolphin" in the list of "missing submarines", and there was no way to know what happened to the "Tiger Dolphin" before it disappeared. It was only after the war that the Japanese Navy's combat records were obtained that it became clear what happened at that time. To this end, Du Xinghua adopted the three orphans of the officers and soldiers of the "Tiger Dolphin" after the war, and provided living expenses for the children of other officers and soldiers every year. Because the Republic Navy adopted a new pension system after the war, there was no need for Du Xinghua to provide tuition for the children of his comrades who sacrificed his comrades.

There are definitely casualties in the war.

The deeds of the "Tiger Dolphin" in risking her life to protect friendly boats have been included in naval textbooks and have become an example for every generation of navy personnel of the Republic to follow. Because it was the first electric submarine to be sunk by the enemy in the war, the "Tiger Dolphin" was also written in the history of the Republic of Navy.

In any case, the officers and men of the "Tiger Dolphin" proved with their actions the will of the republican people to fight as if they were dead.

When the "Thorn Dolphin" left the sea area of battle, it was thousands of kilometers away in the southern waters of the Izu Islands, but the "Finless Porpoise" commanded by Liu Haifeng was quietly approaching its target.

With Du Xinghua, Liu Haifeng also received the "A" combat order at around 3:30 a.m.

Before taking out the combat papers, Liu Hai ordered the "Finless Porpoise" to increase its speed to 6 knots and slowly approach the "Feilong" strategic nuclear submarine in front.

Who knows, the "A" operational order is the highest level of strategic order.

To attack submarines come. This order implies the need to risk sinking the enemy's ground-based strategic nuclear submarines.

It is the newest strategic nuclear ship of the Japanese Navy. The Hiryu, which will be commissioned at the end of 2025, is not only the most advanced submarine in the Japanese Navy. It also has excellent silent performance. Compared to the "Soryu". The "Wyvern" made a sound of less than 1 shell when sailing quietly. At its lowest hour, it was 96 decibels.

This means that the "Finless Porpoise" uses towed passive sonar. It can also track the "Wyvern" only at a distance of 50 kilometers. If you let spherical sonar work in a passive way. The tracking range will be reduced to 25 kilometers.

End of September. When the Navy issues a combat mission. Liu Haifeng and Du Xinghua are both vying to deal with the "Flying Dragon".

According to the unwritten rules of the submarine forces. The two captains decided who would deal with the Wyvern. Liu Haifeng's luck is better than Du Xinghua's. Caught the "sign".

The "Dolphin" discovered the "Flying Dragon" in the waters off the Izu Islands.

There are unwritten "unspoken rules" of submarine warfare. At all times, strategic nuclear submarines are protected in the strictest possible way, with attack submarines underwater, anti-submarine warfare ships on the surface, and anti-submarine patrol aircraft in the air. This is true of the US Navy and the Japanese Navy. The difference is that Japan did not build attack nuclear submarines. It is not that Japan does not have the capability to build attack nuclear submarines, but that Japan is temporarily unable to build attack nuclear submarines with performance comparable to the Republic's electric submarines and the United States' attack nuclear submarines. In the case that performance determines life and death, if it is impossible to build an attack nuclear submarine with advanced performance, it is better to build more AIP conventional submarines with the same funds.

It was the AIP conventional submarine that covered the "Wyvern" under water.

Because the maximum submersible speed of conventional submarines cannot keep up with nuclear submarines, the Japanese Navy has set aside a fixed patrol area for strategic nuclear submarines. The "Soryu," which patrols the waters east of Okinawa, is responsible for threatening the eastern coastal areas of the Republic of China, and the submarine-launched cruise missiles carried are capable of attacking Shanghai, Hangzhou, Suzhou, Nanjing, Wenzhou, and other places. The "Flying Dragon," which patrols the waters south of the Izu Islands, is aimed at major cities in the northeastern part of the Republic and is capable of attacking Dalian, Shenyang, Changchun, and other places with cruise missiles it carries.

The fact that the Japanese Navy did not send a conventional submarine to cover the "Soryu" but sent a conventional submarine to cover the "Flying Dragon" shows how much importance the Japanese Navy attaches to the "Flying Dragon." In the words of Shinsai Sato, the commander-in-chief of the Japanese military department, as long as the "Flying Dragon" is still sailing on the sea, it will be able to destroy 12 large cities in China with a population of more than 5 million, and China will not dare to rashly launch a war against Japan!

The commander-in-chief of the Japanese military department has made cruel remarks, and the navy of the Republic will certainly not give up.

Probably the Japanese Navy also knew that Wakuni listed the "Flying Dragon" as the primary target, so when the "Flying Dragon" went to sea to carry out combat readiness patrol missions, it deployed at least one AIP conventional submarine under the surface of the sea

Six antisubmarine warships were deployed in the nearby waters, and submarine patrol planes were deployed at the home base to take turns to carry out antisubmarine patrol missions in the patrol waters of the "Flying Dragon."

The magic is high and late, and the road is high.

No matter how tightly the Japanese navy's defenses are deployed, it is impossible to ensure that everything is foolproof.

Back at the beginning of 2C26, the Navy of the Republic mastered the characteristic noise of the "Wyvern". At the end of 2026, when the Japanese Navy held a joint anti-submarine exercise with the main purpose of protecting strategic nuclear submarines, the "Finless Porpoise" commanded by Liu Haifeng and the "Thorn Dolphin" commanded by Du Xinghua unknowingly broke through the Japanese Navy's anti-submarine net, discovered the heavily protected "Flying Dragon", and carried out a simulated attack within 20 kilometers.

In accordance with this operation, the Navy adjusted the deployment of submarines, reducing the number of attack submarines that tracked and monitored Japanese strategic nuclear submarines to 2, while during the Peninsular War this number was 3.

Before the outbreak of the war, all attack submarines carrying out the "strategic anti-submarine" mission completed their combat readiness patrol missions.

In Liu Haifeng's view, using two attack boats against one strategic nuclear submarine is simply a waste of the precious strength of the submarine force of the Republic Navy, in addition to giving psychological comfort to the top level of the Republic.

The performance of Japanese strategic nuclear boats can be considered only ordinary. Because the "self-circulating pressurized water reactor" used by it belongs to the first generation of products, the maximum speed will not exceed that of the Dragon when performing combat readiness patrol missions without starting the second-stage circulating pump, and the sailing speed is often controlled below when performing combat readiness patrol missions. Only in this way can its noise be reduced to about 96 belongs. Even so, the Finless Porpoise was still able to easily spot and track the Wyvern. In the three missions that Liu Haifeng carried out to track the "Flying Dragon", he never let the "Flying Dragon" leave the attack range of the "Finless Porpoise".

After receiving the battle order, Liu Hai chose the exact opposite tactic to Du Xinghua.

Instead of firing torpedoes at the "Flying Dragon" 20 kilometers away, the "Jiang" shortened the distance at a speed of 1.5 times that of the "Flying Dragon." The combat mission mentioned that the "Finless Porpoise" must sink the "Flying Dragon" within 12 hours of receiving the order. In Liu Haifeng's view, 12 hours is very sufficient, and there is no need to race against time.

Take advantage of the speed of 2 knots; It took about an hour for the "Finless Porpoise", which was following the "Flying Dragon", to shorten the distance to less than 3 nautical miles. At this distance, not to mention the use of heavy electric anti-submarine torpedoes, even the most old-fashioned anti-submarine torpedoes, can sink the "Wyvern" with nine out of ten.

It is also said that it was not until 7:30 that Liu Haifeng let the "Dolphin" enter the attack position.

When choosing the way to attack, Liu Haifeng had to keep one hand. The first three anti-submarine torpedoes launched by the "Finless Porpoise" were all attacked in a two-speed self-guided manner, of which two torpedoes were fired at the "Flying Dragon" and one torpedo was fired at the Japanese AIP conventional submarine about 1C km away from the "Flying Dragon" and about 4 km away from the "Finless Porpoise." Even if he attacked the "Flying Dragon" with only 2 torpedoes, Liu Haifeng was sure enough. Before launching the torpedo, Liu Haifeng also asked his partner Zhang Xuefeng to control the fire control system and input the parameters of the other three Japanese AIP conventional submarines for the other three torpedoes. Although the distance is a little farther, and Liu Haifeng does not want to bury the "Finless Porpoise" for a few Japanese conventional submarines in the sea area where Japan's antisubmarine patrol planes and antisubmarine warships are concentrated, the "Finless Porpoise" can launch an attack at the fastest speed as long as the Japanese submarine acts rashly.

Without asking, Liu Haifeng is a ruthless character.

The actual situation was much better than Liu Haifeng expected. When the "Flying Dragon" discovered the approaching torpedo, it did not have time to maneuver to evade it, let alone float to the periscope depth and launch 12 large hypersonic submarine-launched cruise missiles weighing 15 to 15 that were stored in vertical launch tubes. After throwing several anti-torpedo decoys in succession, the "Wyvern" was hit by 2 heavy torpedoes in a row without the ability to resist. Before sinking to the bottom of the sea, which reached a depth of one meter, the "Flying Dragon," which had an underwater displacement of more than 1,500 tons, broke into three parts, and 127 officers and men embarked on the Huangquan Road along with 12 hypersonic cruise missiles, which symbolize the highest strategic strike capability of the Yamato nation.

Subsequently, the Japanese conventional submarine covering the "Wyvern" was also sunk by heavy torpedoes.

When the Japanese antisubmarine patrol plane arrived, the first thing they searched was not the sea area where the "Finless Porpoise" was located, but the sea area between the "Flying Dragon" and the conventional submarine. Presumably, the captain of the Japanese anti-submarine patrol plane thought that the Republic submarine that ambushed the "Flying Dragon" was ambushed between the "Flying Dragon" and the conventional submarine.

Taking advantage of this opportunity, the "Finless Porpoise" quickly turned away.

After sailing out of the search range of the Japanese anti-submarine patrol aircraft, the "Finless Porpoise" increased its speed to 37 knots in order to leave the dangerous sea area as soon as possible and avoid being attacked.

At about 8 o'clock, Liu Haifeng let the "finless porpoise" launch the communication buoy.
