In general, tracking strategic nuclear submarines is not a "fun" thing. 【No pop-up novel network】『bubble book』

Du Xinghua has served on the submarine for more than 20 years, and during his tenure as captain of the "Killer Whale", he has repeatedly carried out many missions to track Russian and American strategic nuclear submarines. After the United States deployed the "Ohio" class, which was converted into a "cruise missile submarine," to Guam, Du Xinghua carried out a "tracking mission" within two years.

Unlike attack nuclear submarines, known as "deep-sea assassins", strategic nuclear submarines are the Navy's key objects of protection.

During the Cold War between the United States and the Soviet Union, the Red Navy not only regarded strategic nuclear submarines as its pillar force, but also regarded the protection of strategic nuclear submarines as its number one task. Although the United States is not as "extreme" as the Soviet Union, the US Navy still uses more than half of its attack nuclear submarines to protect strategic nuclear submarines.

Japan does not fall under the category of "general circumstances", but "special circumstances".

Like France, Japan builds strategic nuclear submarines first, and not attack nuclear submarines first. The advantage of this is that the "second strike capability" can be obtained as soon as possible, and the disadvantage is the lack of protection of strategic nuclear submarines.

Actual combat has proved that neither anti-submarine aviation nor anti-submarine warships can effectively deal with nuclear submarines with advanced performance.

The most powerful anti-submarine weapon is a much more advanced submarine.

Conventional submarines, even AIP conventional submarines, cannot keep up with the voyage of nuclear submarines, and the diving time is far inferior to that of nuclear submarines; Surface warships are easily spotted by reconnaissance satellites, and there are no secrets to their whereabouts; Anti-submarine aircraft have a very limited patrol time and are not able to provide continuous protection for strategic nuclear submarines. Only attack nuclear submarines, or "electric submarines" with comparable performance, can accompany the activities of strategic nuclear submarines and provide the most effective cover for strategic nuclear submarines.

At the time of the outbreak of the war on the peninsula, Japan had not yet attacked nuclear submarines.

Strictly speaking. The Japanese ground-2 strategic nuclear submarine is an attack nuclear submarine. Because only submarine-launched cruise missiles are equipped. It is not equipped with SLBMs.

The performance of "Dongying Chrysanthemum" is very "bad".

It is more than 1C0 kilometers away. The passive sonar on the side of the "Thorn Dolphin" intercepted the loud noise of the "East Chrysanthemum" coming out of the ground. The course and speed were measured.

Du Xinghua played a game of "cat and mouse" with Japanese submarines in strict accordance with the "rules."

Because there are obvious signs before a strategic nuclear submarine launches a missile. The National Strategic Early Warning System will issue warnings in advance. Therefore, the "Thorn Dolphin" has been trailing behind the butt of the "Dongying Chrysanthemum". The distance is kept between 150 chains and 2C0. When the "Dongying Chrysanthemum" sailed westward. Du Xinghua will shorten the distance a little. Otherwise, the distance is slightly wider. The main thing is that the Japanese submarine-launched cruise missiles have a ground range of only 1,500 kilometers. It is necessary to reach about 350 kilometers east of the Togara Islands before it can attack the large cities of the eastern coastal areas of the Republic of China such as Shanghai and Hangzhou. Du Xinghua had already received the order. As long as the "East Chrysanthemum" dares to "act rashly". It can be sunk without asking for permission. Of course. Submarines will never be like warships or warplanes. Give a warning before attacking.

December 211. On the third day of the outbreak of the Korean Peninsula War.

The "Dolphin" and "White-sided Dolphin" arrived and joined the "Cat and Mouse" game.

Although two Japanese conventional submarines had arrived before this and laid ambush at both ends of the "East Chrysanthemum" patrol area, Du Xinghua did not pay attention to the conventional submarines at all. Even without the support of the two sister boats, Du Xinghua was absolutely sure that he would take out three Japanese submarines within three minutes.

What made Du Xinghua a little incredulous was that the Japanese submarine did not seem to have three "of the same kind" in the vicinity.

The boring "tracking mission" lasts until the afternoon of January 2025.

After receiving the "strategic telegram" from the ultra-longwave radio station, Du Xinghua immediately ordered the submarine to rise to the depth of the periscope, extend the satellite communication antenna out of the sea, and receive the new order.

When the submarine dived, Du Xinghua breathed a sigh of relief.

The order was not for the "Thornfish" to sink the "Dongying Chrysanthemum", but to rush to the sea near Jeju Island within 2 days.

Although the order did not mention anything unrelated to submarine operations, Du Xinghua had already guessed that the Marines were about to attack Jeju Island, and the aircraft carrier battle group would provide support to the Marines. In order to ensure the safety of aircraft carrier battle groups, more submarines are needed to perform "escort anti-submarine" missions. The order clearly mentions that the "Thornfish" is carrying out a "free hunt" mission, and from the early morning of the 7th, it can sink all "enemy ships" that enter the theater of operations and pose a threat to the aircraft carrier battle group or the ships of the Republic Navy without asking for instructions.

Rushing to the war zone on time has become Du Xinghua's biggest headache.

The submarines of the Republic of China Navy enter the western Pacific Ocean in three main "underwater corridors": from north to south, the "underwater plank road" between the Miyako Islands and the Okinawa Islands, a narrow channel located in the Okinawa Ridge, an underwater channel north of the Taiwan Trench in the "central corridor" between Yonaguni Island and the island of Taiwan, and an underwater channel in the middle of the Bashi Strait, a "submarine fast lane". In general, electric submarines with a smaller displacement and quieter prefer to walk on the "underwater plank road", while nuclear submarines with a larger displacement and more obvious noise like to walk

lanes".

Needless to say, these three "underwater corridors" are all under the control of people.

After the reconquest of the Diaoyu Islands, the Navy of the Republic has been looking for new underwater passages.

Electric submarines are in large-scale service and become "main battle" submarines, making it easier for the Navy to get in and out of the Western Pacific. The main thing is that electric submarines are more agile, quieter and more suitable for navigating shallow waters.

In 2023, Du Xinghua commanded the "Thorn Dolphin" to conduct its third patrol, entering and exiting the western Pacific Ocean from the Tura Strait.

Compared to the "underwater plank road", the average water depth of the Tugara Strait is close to 200, which is more suitable for submarine traffic. The biggest problem is that the Kuroshio Current, also known as the Japan Warm Current, originates in the Philippine Sea Basin, travels north along the eastern waters of the Philippine Islands, passes through the eastern waters of the Ryukyu Islands, travels northward along the eastern part of the Japanese mainland, and finally joins the North Pacific Warm Current. In addition to the warm current close to the sea surface, there is also a reverse cold current at a depth of less than 350 meters that changes in direction and speed with the season and temperature.

For fishermen living in the Tura archipelago, converging currents are the basis for a bountiful harvest.

For submarines trying to pass through the Togara Strait, the converging currents are a harbinger of disaster.

After getting rid of the "control" of the United States, Japan not only strengthened the "submarine sonar network" established by the United States in the Osumi Strait during the Cold War, but also established a new "submarine sonar network" in the Tura Strait and strengthened the blockade of the Republic's navy. According to the plan drawn up by the Japanese Navy, by 203, a "submarine sonar network" will be established in all the straits of the Ryukyu Islands that can be navigated by submarines.

Despite its advanced performance, the Thornfish still produces fluid noise at high speeds.

In order to avoid revealing their whereabouts, submarines must reduce their speed to a minimum and minimize noise when passing through a narrow sea area with a "submarine sonar net".

Du Xinghua proved in practice that the "Thorn Dolphin" was able to "safely" pass through the Tura Strait at its speed.

The problem is that Du Xinghua chose to pass through the Tura Strait in July, when the influence of the warm current is the weakest, but now he has to enter the "minefield" in January, when the influence of the warm current is the strongest.

The difference in time creates an insurmountable obstacle.

If there was another choice, Du Xinghua would not risk his life with 35 submarines, 33 officers and men. Instead of returning to the Yellow Sea from the Tura Strait, you can only take the "underwater plank road", which will make a detour of 650 nautical miles. Even if the "Thorn Dolphin" threw off its feet and ran away, it could only reach the war zone after 60 at the earliest, and could not arrive within 2 days.

For military personnel, the execution of orders is more important than anything else.

If the "Thorn Dolphin" did not arrive in time for the war zone, resulting in the aircraft carrier battle group being attacked by a stick submarine, Du Xinghua would never forgive himself.

War is inherently fraught with danger, and reasonable risk can pay off handsomely.

At least Du Xinghua thinks so.

After Hua Jianfeng left the "front line", Du Xinghua nominally became the "number one submarine captain" of the republic, but in fact, he has not broken several records set by Hua Jianfeng. Regardless of the number of sunken ships, tonnage, and number of battles, Hua Jianfeng is still the indisputable "number one trump card".

After "intersecting" with Hua Jianfeng for decades, Du Xinghua knows what his problems are.

In terms of ability, Du Xinghua is no worse than Hua Jianfeng. At the Naval Submarine Academy, Du Xinghua's grades in several subjects were even better than Hua Jianfeng's. Du Xinghua lacked only one thing: an adventurous spirit.

It's not that Du Xinghua doesn't dare to take risks, but when he makes risky decisions, he always has some concerns.

This is both a good habit and a bad habit.

Caution is a quality that a submarine captain must have, and Hua Jianfeng is no exception, when it comes to adventures, he is more cautious than anyone else. It's just that when you are too cautious and too cautious, you will miss a lot of opportunities. As the saying goes, opportunities don't wait, they are created!

Now there is no other choice, so Du Xinghua has to take risks.

Unlike Hua Jianfeng, Du Xinghua is not so "chic". After asking his partner Rong Kangjian to modify the route, Du Xinghua stayed in the command center. Although he did not interfere with Rong Kangjian's command work, everyone knew Du Xinghua's concerns.

Will Japan do the trick?

Du Xinghua can't be sure, and neither can Rong Kangjian.

Submarine warfare is different from other battles, and if a Japanese submarine is ambushed in the Togara Strait and the "Thornfish" is taken out by surprise, I am afraid that it will be like Hua Jianfeng who killed the US Navy's attack nuclear submarine in the waters off the Okinawa Islands, and no one will take it seriously.

If you really want to end up like this, you will die too unjustly.

Du Xinghua doesn't want to die in a daze, no one wants to die silently.

When the submarine arrived at the eastern entrance of the underwater channel of the Tugara Strait, Du Xinghua took over the command and personally directed the submarine to enter the channel.

Whether there is no return or no danger, we will see after more than ten hours.

In the last few days of the month, the top six are guaranteed and the brothers are begged to provide monthly passes
