When Xiaolei arrived at the "Huaxia" aircraft carrier, the "Thorn Dolphin" submarine was diving

"Lao Du, return?"

Du Xinghua glanced at his partner Rong Kangjian and said: "Reset the route, enter the Yellow Sea from the Tugara Strait, and look for opportunities to the west of the Men's and Women's Islands and the south of Jeju Island." 【】『Bubble Book』"

Rong Kangjian frowned slightly, and said, "It's too dangerous to go through the Tugara Strait, we should ......"

"It is necessary to reach the war zone within forty-eight hours." Du Xinghua knocked on the screen and said, "The order is very clear, the task of tracking the Japanese strategic nuclear submarine is the responsibility of the other two submarines, and we must reach the waters near Jeju Island within two days to search for and attack South Korean submarines and warships to assist the aircraft carrier battle group in combat." ”

"But ......"

"I know it's really dangerous to go through the Togara Strait." Du Xinghua rubbed his face, "Reach the east side of the strait, turn off the reactor, and propulsion with full electric power." The sailing depth is set below 450 meters, making full use of the reverse current. If all goes well, we can reach the war zone in forty hours. ”

"Below four hundred and fifty meters?" Rong Kangjian was stunned for a moment, "Our charts are not perfect enough......"

"The channel of the Tura Strait is what we have drawn, don't you have confidence?"

Seeing Du Xinghua, he looked confident. Rong Kangjian sighed secretly. Didn't say anything more.

The submarine continued to dive. It was leveled after reaching a depth of 350 meters. It then sailed westward at 16 knots.

The "Thorn Dolphin" is the third of the most advanced C75 "Dolphin" class "nuclear power hybrid propulsion" submarines of the Republic of China Navy. The classification of the nature of the "dolphin" class has always been controversial. Because it is equipped with a fusion reactor. So some people think that it should be attributed to the "nuclear submarine". And because the main power source is the composite battery. So some people think that it should be attributed to "electric submarines". Start with the "Dolphin" class. The nomenclature rules for submarines of the Republic Navy have changed. In addition to continuing to be named by the codename. Level names have also been added. Each submarine was named separately. 5 Medium-Earth submarines are codenamed in the Navy. 7 is the code name of the electric submarine, so most people think that the "Dolphin" class belongs to the electric submarine. 5 is the specific level.

Compared to the "Swordfish". The biggest "feature" of the "Thornfish" is the addition of a small fusion reactor.

Fusion reactors do not directly drive superconducting electric motors. Instead, the composite battery is powered by a "closed-cycle thermo-electric energy conversion system". Compared to conventional ground fission reactors. The advantages of fusion reactors are very prominent. Relying on the reserve in the reactor core, in the special container in the interior of the reactor, the ground element is actually in a state of storage, which is a catalytic metal. Fusion reactors can operate continuously for 30 years, and the design life of submarines is 30 years. There is no need to refuel halfway; Fusion reactors do not produce any radiation when they are stopped. During operation, only ground rays and a small amount of L-rays are emitted, which are relatively easy to shield. It will not cause serious radioactive contamination; The noise of the ground is very low when the reactor is working. Conducive to submarine concealment; It only takes 15 minutes to go from shutdown to full power operation. The response speed is much faster than that of fission reactors. And it can be quickly started in any state; The overall mass of the reactor with a volume of less than 150:. It is only one-third of the fission reactor of the same level.

Fusion reactors are used as an indirect source of energy. It's not that you can't build a fusion reactor with more power. It's not necessary.

Weapons and equipment are different from civilian equipment, the operating environment is complex and changeable, and they are too limited by tactical technology. In actual combat, the submarine will control the sailing speed and depth according to various situations such as the combat environment, combat missions, and belligerent opponents, and attack in the best way to leave the dangerous area as quickly as possible. Although the corresponding speed of the fusion reactor is very fast, the output power cannot be flexibly adjusted, and the propulsion power varies greatly when the submarine changes its sailing speed. The use of composite batteries as a direct energy source can effectively compensate for the shortcomings of fusion reactors.

"Swordfish" has already proven the performance of an all-electric submarine.

Without the use of fusion reactors, the Dolphin can dive at a speed of 35 knots or 3,500 nautical miles at a speed of 6 knots, relying only on the electrical energy in the composite battery. This performance not only surpasses that of all AIP conventional submarines, but also ensures that the "Thornfish" can leave the dangerous sea area or approach the target covertly under any circumstances.

Thanks to the addition of the "reactor compartment", the total length of the "Thornfish" reached 98 meters, and the underwater displacement was 5800: .

The main purpose of the hull growth was not to carry more composite batteries, which were actually only one-third of those of the Swordfish, but to install a longer sideboard passive sonar array. It has been proved in actual combat that the broadside passive sonar base array is the most used sonar, and it is also the most important sonar of submarines in combat. No captain wants a submarine to drag a tail several kilometers long to pursue prey or hide from the enemy, and no captain wants to risk revealing his whereabouts while engaging the enemy to retract the towed sonar. The bow spherical active and passive sonar is an attack sonar that is only used when you are in absolute upper hand.

Although decades ago, the United States confirmed it on the "Big Mackerel".

The best shape is "teardrop-shaped", but there are almost no countries that are subtly "teardrop-shaped", but more "cigar-shaped" with the same diameter as the middle section. In addition to the greater difficulty of manufacturing the "teardrop-shaped" pressure-resistant shell, the main reason is that the length of the middle section of the hull is too short to install high-performance sideboard sonar. In fact, whenever possible, all national surface nuclear submarines will try to increase the length of their hulls in order to install a longer broadside sonar with a base array.

From this "change", the "Thorn Dolphin" has gained more powerful combat capabilities.

The main purpose of increasing the displacement is twofold, one is to enhance the ability to carry mines, and the other is to improve the living environment of the crew.

The "Swordfish" has too little ammunition in reserve, and it has always been criticized. During his tenure as captain of the "Swordfish," Hua Jianfeng wrote five reports to the Naval Armament Department and the Armament Division of the General Staff Headquarters, all of which clearly mentioned that the bomb-carrying capacity of the submarine should be increased and the "multi-mission capability" of the submarine in complex situations should be enhanced.

When designing the "Dolphin" class, the designers of the Ship Research Institute fully took into account the opinions of the "users".

The Thorndolphin is capable of carrying 38 torpedoes and missiles in the torpedo bay, as well as 12 anti-ship missiles or cruise missiles in a vertical firing system behind the spherical sonar compartment in the bow. The most "unusual" thing is that the designers left a sealed cabin with a volume of about one cubic meter behind the shell of the submarine command platform, which was ready to be used to load submarine-launched anti-aircraft missiles, but the supporting missiles have not been successfully developed. Under normal circumstances, in addition to carrying 12 vertically launched missiles, which are generally 8 cruise missiles and anti-ship missiles, the "Thornfish" also loads anti-ship missiles in the torpedo compartment, and the rest of the bomb racks are all used to place heavy anti-ship and anti-submarine dual-purpose electric torpedoes.

Another difference from the "Swordfish" is that the "Dolphin" is equipped with three 650-mm torpedo tubes on the left and right ribs. Although the "Thornfish" still needs to add adaptive washers to the torpedo when it is still fired with a 533 mm diameter heavy torpedo, in the future, it can use the "super heavy torpedo" with a longer range and more advanced performance, or a long-range cruise missile with a larger caliber.

Improving the living environment of submarines is the thing that all submarine officers and men, including Du Xinghua, are most concerned about.

In fact, the living facilities of the "Swordfish" are already very good. Compared with the "Swordfish", the "Thornfish" not only provided separate cabins for officers, but also reduced the number of sailors to people, and reserved 16 bunks for special forces. The biggest improvements are the entertainment facilities, such as the 250-mile library on board the "Thorn Dolphin," the fact that officers and men can also search for their favorite works from tens of thousands of electronic books stored in the central computer system through the on-board network system, and the small cinema with 16 seats allows officers and men who are resting on shifts to obtain more abundant entertainment activities.

Improving the living environment of officers and men can maximize the "in-flight rate" of submarines.

Although the "mission time" of the "Dolphin" class is designed to refer to the time from leaving the base to returning to the base, the "Dolphin" set a record of 75 days of diving after it entered service, and the "Thorn Dolphin" set a record of 120 days of continuous diving on its third voyage.

For a nuclear hybrid submarine with "unlimited endurance", the sailing time is not determined by the capacity of the battery, but by the endurance of the officers and men. Submariners are also human beings, and without rich entertainment activities and a "superior" living environment, anyone who stays in an "iron pipe" for a long time will go crazy.

Of course, in the eyes of submariners, life on submarines can definitely not be described as "superior".

The "Dolphin" sailed from the north of the Miyako Islands into the western Pacific Ocean in early December, heading for the Kitam Strait in Japan, also known as the Tomoshima Waterway, and the exit of Osaka Bay in search of "prey".

After Hua Jianfeng "retired", Du Xinghua became the number one submarine captain in the Republic.

According to tradition, the "Thorn Dolphin" commanded by Du Xinghua was sent to carry out the most important and boring task: to track and monitor the enemy's strategic nuclear submarines, and to sink the enemy's strategic nuclear submarines as soon as the war began.

In the past, this task was carried out by attack nuclear submarines, but because Japan was very close to the Republic, the Navy sent quieter "electric submarines".

Soon after sinking on a shallow beach in the southwest of the Kii Peninsula at Deadwood Beach, the "Thornfish" appeared as a "prey".

Japan's conventional submarines are advanced, but nuclear submarines are not so good.

Du Xinghua didn't spend much effort to keep up with the Japanese strategic nuclear submarine codenamed "Dongying Chrysanthemum" and the other Japanese strategic nuclear submarine codenamed "Yamato Chrysanthemum".

What he didn't expect was that within a few days, the war on the peninsula broke out.

The sudden war not only disrupted the "schedule" of the Japanese nuclear submarine, but also disrupted Du Xinghua's "activity schedule", because Du Xinghua had to give up his "plan" to take leave to go home and get married.

In the last few days of the month, keep the top six and ask the brothers for a monthly pass
