Infernal Hero Chapter 400: It’s so deep

On the rough sea, the "Sailfish" broke out like a giant whale. It was not until one-third of the hull was exposed to the air that it hit the sea heavily. Immediately, the submarine was swallowed up by the huge waves, and when the command platform surfaced again, the submarine was already floating on the sea.

98 meters long, about 12.5 meters wide, with a dark body, the hull is like an elongated cigar, with a streamlined podium, retractable bow level rudder, and x-shaped tail rudder, which are sprayed by a pump. propeller drive. Equipped with a military-grade composite battery with a mass-energy ratio of 12,000 kWh per kilogram.

How significant is the mass-energy ratio of 12,000 kWh per kilogram?

The calorific value of diesel combustion is 40,000 kilojoules per kilogram, and the calorific value of gasoline combustion is 44,000 kilojoules per kilogram. The new military-grade composite battery can store 38,800 kilojoules of electricity per kilogram. , has been infinitely close to the efficiency ratio of diesel and gasoline.

The thermal efficiency of the direct-injection internal combustion engine is about 50%, and the energy conversion efficiency of the new superconducting motor is over 70%. The power propulsion system composed of military-grade new composite batteries and superconducting motors can completely replace the power propulsion system composed of diesel, internal combustion engine and ordinary batteries, so that conventional submarines have a real "aip", that is, "air-independent propulsion". For the submarine industry, this is an epoch-making technological advancement of great strategic significance.

The "Sailfish" is equipped with a 500-ton military composite battery and an 8,600-kilowatt superconducting motor. After being fully charged, it can dive for 296 at a top speed of 32 knots. 8,000 nautical miles in 12 days in 1 hour; if the submersible speed is reduced to six knots, it can submerge for 72 days and travel 10,000 nautical miles without having to surface for air during the entire patrol mission. Relatively speaking, even a 212-class conventional submarine equipped with fuel cells can only submerge for up to 21 days, and if it sails at maximum underwater speed, it can only last for a few hours.

With the exception of an emergency diesel generator set, the Sailfish has no conventional power equipment and no major source of noise. Combined with the pump-jet propulsion system, the Sailfish's noise levels have been reduced to unprecedented levels. When sailing at a speed of six knots, its own noise is less than 70 decibels; even if the speed is increased to the conventional top speed of 32 knots, it is only 98 decibels, which is far lower than any conventional submarine, and even higher than the US Navy's " Virginia” class nuclear submarines are several decibels lower.

A 35-centimeter-thick sound-absorbing tile was installed on the outer surface of the "Sailfish" hull, which shortened the detection range of the enemy boat's active sonar by two-thirds. Combined with very low self-noise, the Sailfish is the quietest submarine in the world.

In terms of cost, this is perhaps the most extravagant submarine in the world right now. Military composite batteries are extremely expensive. The price of a five-hundred-ton battery has exceeded that of an attack nuclear submarine, but its endurance is far less than that of a nuclear submarine. Members of its design team believe that adding a small fusion reactor to the Sailfish would give it an "infinite range" capability. Unfortunately, the mission this time was too urgent. The several nuclear submarines under the command of the Republic Navy were secretly monitored by the United States Navy and did not dare to act rashly, so they had to be dispatched. As a rescue mission with an acting nature, although it is a bit overkill, the difficulty level is just right.

Don River used to be an excellent submarine commander. Ten years ago, when he was about to be promoted to the twenty-second nuclear submarine captain of the Republic, Sun Mingshen's order made him bid farewell to his beloved submarine and take off The uniform became the captain of an ocean-going freighter. Years of espionage did not kill his longing for the depths of the sea, but only increased his nostalgia for his beloved submarine command post.

This time, Sun Mingshen, as the security commander of the new equipment experimental unit, gave him the command of the world's first all-electric submarine. Commendation.

Gu Tianyou and his party followed him into the inside of this mysterious submarine, only listening to the Don River's introduction: because the length of the "Sailfish" is only 98 meters, and the length of the middle cylindrical cabin is only Sixty-five meters, which makes this place a little cramped, not as spacious as a nuclear-powered submarine, so you have to overcome it.

Gu Tianyou is now Grandma Liu who entered the Grand View Garden and asked a few questions when she saw it. Don He patiently gave a highly professional answer. During this period, Pei Lan was silent at first, and later also participated in the discussion. His questions were more professional than Brother Tianyou. The questions are all about key data in the submarine field. Don didn't seem to be prepared to have reservations about him, and took the trouble to answer his questions endlessly.

The length of the passive sonar array on the side of the "Sailfish" is only 50 meters, which is nearly 30 meters shorter than the passive sonar array on the attack nuclear submarine. The performance of passive sonar, especially for sound sources The azimuth detection accuracy is therefore greatly reduced.

Because of the limited space at the bow, even if the fish bud cabin is moved back and the four fish bud launch tubes are installed on the rib of the submarine, it can only be equipped with the first spherical active/passive sonar with a diameter of six meters, so the "sailfish" "The performance of the active sonar is not as good as the 096 level. Due to the limitation of the internal space of the hull, the "Sailfish" can only carry 22 buds and missiles, which is indeed much inferior to the 38 buds and missiles of the 096 class.

For a conventional submarine with an underwater displacement of only 3,850 tons, the performance of the "Sailfish" is already very outstanding. Not only is there no conventional submarine that can match it, even Some second-rate naval attack submarines are not necessarily much better than the Sailfish. As far as the characteristics of the laws of actual submarine combat are concerned, perhaps the actual combat performance of the Sailfish is even higher.

The speed is faster, quieter, the presence of the opponent is detected first, the position of the opponent is detected, and the more advanced firepower configuration is often the key factor that determines the success or failure of a submarine-to-submarine confrontation. The Sailfish already leads the industry in being quieter. The speed is not inferior to that of nuclear-powered submarines, and the endurance is far better than that of ordinary conventional submarines. It can be said that the sailfish may not fully represent the present of the submarine industry, but it can definitely lead the future trend of confrontation in this line.

In addition to having a strong "heart" and a sufficiently large "lung", the "Sailfish" also has a well-developed "brain".

The highly automated operating system eliminates the jobs saved by conventional power equipment, and reduces the number of officers and soldiers of the "Sailfish" to 36 people. Usually, only eight people can control the entire submarine. The highly integrated detection, search and fire control system, coupled with the central computer running 250 million times per second, enables the "Sailfish" to have the most acute response speed. In a state of engagement, the Sailfish can control four buds to attack the two most threatening targets while tracking eight targets.

Being inside this steel body, I feel an unprecedented pride in my heart. The dream of a strong country has never been clearer at this moment. Gu Tianyou deeply knew that the beginning of all this began with his discovery. Lao Tzu is a person who has made great contributions to this country!

Don River is still introducing the Sailfish, with an air that is like introducing his own son, who has excellent grades and talent.

A good horse with a good saddle, a warrior with a sword.

The Sailfish is equipped with state-of-the-art weapons, especially heavy buds.

The new electric fish bud uses a composite battery as the power source. In the high-speed mode of 70 knots, the range can reach 35 kilometers; in the low-speed mode of 45 knots, the range can reach 65 kilometers. A war thunderhead loaded with 250 kilograms of high-energy explosives is enough to cause a single bud to damage a destroyer, two buds to damage a cruiser, and three buds to incapacitate an aircraft carrier. And the accuracy and stability are far higher than the conventional fish buds commonly used in contemporary times.

In the sailor cabin, Gu Tianyou and others were tasting hot milk tea and cakes with very poor taste. Don was accompanied by his deputy, who cannot be named.

Gu Tianyou said, "I really didn't expect to be able to go back with this advanced stuff on this trip." He looked up and saw Sun Jingfei, who seemed a little uncomfortable, his brows furrowed and his face turned pale, and he casually asked what's the matter with you? Sun Jingfei said: "I am a little sensitive to claustrophobic spaces, and it is difficult to restrain myself."

The code name of Don He's deputy is Kunpeng. He is a relatively young major officer. It can be seen that he is a little curious about Gu Tianyou and others. It's just limited by the rules of this line, so many words are difficult to speak freely.

As the submarine's chief mate and commander, he is the one who knows the submarine best. Perrin was asking him how long it would take to assemble such a submarine at the current level of industry in the Republic? Kunpeng just smiled, his authority is probably not as large as the Don River, so he can't know everything like the Don River. If he can answer, he will say a few words, and if he can't answer, he will laugh and say nothing.

Perrin is already a prisoner and will never have the chance to leave the Republic in this life. Gu Tianyou didn't think there was any secret worth hiding from him. Because the rest of his life will surely be spent in the secret cell of Guoan. Before boarding the ship, Gu Tianyou had searched him carefully, and several micro electronic devices, including the micro communicator implanted under the ear door, had been found. At this time, he should not have the conditions for leaking secrets.

Don He signaled that the others could rest, then lost a look at Gu Tianyou, and went out of the watertight cabin with Kunpeng. Gu Tianyou knew that he had something to say to him alone, so I told Xiaolongnu I went over to see Look, follow.

In the command room, Kunpeng stood in front of the operating table, with his hands behind his back, staring intently at the constantly beating numbers on the electronic depth gauge.

200 meters, 250 meters, 300 meters... When the reading became 350, Kunpeng pressed the helmsman's shoulder.

"Five on the first, ten on the bottom, keep the speed."

The helmsman figured it out and first adjusted the index on the depth controller to 330, then adjusted the index on the speed controller, and finally stabilized the directional controller that looked like a car steering wheel. Next, the automatic control equipment on the submarine adjusts the sailing state of the submarine, without direct manipulation by the helmsman. A submarine with a displacement of several thousand tons is not a car. It took about ten seconds for the speed of the submarine to drop.

The sonar chief kept his hands on the headset, listening intently. Adjust the knobs of the sonar control panel from time to time, staring at the sonar screen without blinking. Kunpeng looked at it with concern and asked, "How is it? Did you hear any movement?" The sonar chief shook his head, indicating that no sound was received.

"Not found, not the best answer, but the worst answer!" Don He's expression was a little solemn. His sturdy face as carved by a knife did not show the slightest emotional fluctuations, but a pair of dark eyes flashed with hot and fierce emotions like fire. Shen Sheng continued: "Three hours ago, we detected a sound reflection in the strait to the northwest, most likely an Ohio-class submarine of the United States Navy, the sonar recorded the other party's characteristic noise, but now we have lost trace of it."

Gu Tianyou is a complete stick in this regard, asking: "If you can't find it, it means they are gone. Isn't that a good thing?"

Don He shook his head solemnly and said, "Of course not, but this is a problem of tactical command, it's my problem, and I invited you here to convey to you the Sun Bureau's separate order for you." Saying that, he handed over a USB flash drive. Said: "This thing has a self-destruction program, it can only be opened once, and it will be automatically destroyed after reading it."

According to Don River's instructions, Gu Tianyou walked into the captain's quarters next to the command room alone. There was a laptop that had been turned on and placed there. After inserting the USB flash drive, he opened it and looked at the contents. . Sun Mingshen actually let himself find an opportunity to rescue Peilan after landing, and he also sent him back to the kingdoms! As the screen quickly turned into a snowflake, the self-destruction program here really started in time.

This Perrin came here on his own initiative. Just now, the Don River told him so many core secrets about this electric submarine. Now Sun Mingshen ordered himself to save this man and go to the nations? What the **** is this old man doing?
