On the rough sea, the "Sailfish" broke through the water like a giant whale, and only after a third of the hull was exposed to the air, it slammed into the sea. Soon, the submarine was swallowed up by www.biquge.info the waves, and by the time the command platform was exposed again, the submarine was already floating on the surface.

Ninety-eight meters long and about 12.5 meters wide, the hull is as dark as an elongated cigar smoke, with a streamlined command platform, retractable head horizontal rudders, and X-shaped tail rudders, driven by pump-jet thrusters. It is equipped with a military-grade composite battery with a mass-to-energy ratio of 12,000 kWh per kilogram.

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

The calorific value of diesel combustion is 40,000 kilojoules per kilogram, the calorific value of gasoline combustion is 44,000 kilojoules per kilogram, and each kilogram of military-grade new composite batteries can store 38,800 kilojoules of electrical energy, which is infinitely close to the efficiency ratio of diesel and gasoline.

The thermal efficiency of the direct injection internal combustion engine is about 50 percent, and the energy conversion efficiency of the new superconducting motor is more than 70 percent. The power propulsion system composed of new military-grade composite batteries and superconducting motors can completely replace the power propulsion system composed of diesel, internal combustion engines and ordinary batteries, so that conventional submarines have a real "AIP", that is, "independent of air propulsion". As far as the submarine industry is concerned, this is an epoch-making technological progress of great strategic significance.

Equipped with a 500-ton military composite battery and an 8,600-kilowatt superconducting electric motor, the "Sailfish" will be able to dive for 296 hours at a maximum speed of 32 knots and sail 8,000 nautical miles in 12 days after being fully charged. Comparatively speaking, even a conventional 212-class submarine equipped with fuel cells can only dive for a maximum of 21 days, and if it is sailing at maximum underwater speed, it can only last for several hours.

Apart from an emergency diesel generator set, the Sailfish submarine had no conventional power equipment and therefore no major source of noise. Combined with a pump-jet propulsion system, the noise level of the Sailfish was reduced to an unprecedented level. When sailing at a speed of six knots, its own noise is less than 70 decibels, and even if the speed is increased to a normal top speed of 32 knots, it is only 98 decibels, which is far lower than any conventional submarine, and even lower than the US Navy's "Virginia"-class nuclear submarines.

The outer surface of the "Sailfish" boat is covered with a 35-centimeter-thick sound-absorbing tile, which shortens the detection range of the enemy's active sonar by two-thirds. Coupled with very low self-noise, the Sailfish became the quietest submarine in the world.

In terms of cost, this is perhaps the most extravagant submarine in the world at the moment. Military composite batteries are extremely expensive, the price of a five-hundred-ton battery is already more than that of an attack nuclear submarine, while its endurance is much inferior to that of a nuclear submarine. Its design team members believe that adding a small fusion reactor to the Sailfish would give it "unlimited endurance." Unfortunately, this mission was too urgent, and the few nuclear submarines under the command of the Navy of the Republic were secretly monitored by the Navy of the United States and did not dare to act rashly, so they had to send them out. As a rescue mission with an acting nature, although it is a bit overkill, the difficulty level is just right.

Don was once an excellent submarine commander, and ten years ago, when he was about to become the 22nd commander of the nuclear submarine of the Republic, Sun Mingshen ordered him to bid farewell to his beloved submarine and take off his military uniform to become the captain of an ocean-going freighter. Years of espionage did not wear away his desire for the depths of the sea, but only increased his attachment to his beloved submarine command post.

This time, Sun Mingshen, as the security commander of the new equipment experimental unit, handed over the world's first all-electric submarine to him for command, which can be regarded as a kind of praise for his silent efforts over the years and obedience to the overall situation of the country's needs.

Gu Tianyou and his entourage followed him into the interior of this mysterious submarine, and only listened to the introduction of the Don River: because the length of the "Sailfish" is only 98 meters, and the length of the cylindrical compartment in the middle is only 65 meters, this place is a little cramped, and it will not be as spacious as a nuclear-powered submarine, so you have to overcome it.

Gu Tianyou is now Grandma Liu who has entered the Grand View Garden, and she will ask a few words when she sees anything. Don River is very patient and makes a very professional answer. During this period, Pei Lan was silent at first, and later participated in the discussion, and his questions were much more professional than Brother Tianyou. The questions are about the key data in the field of submarines. Don didn't seem to be ready to hold back on him, and took the trouble to answer his questions.

The length of the passive sonar base array on the side of the "Sailfish" is only 50 meters, which is nearly 30 meters shorter than that of the passive sonar base array on the attack nuclear submarine, and the performance of the passive sonar, especially the accuracy of detecting the direction of the sound source, has been greatly reduced.

Because of the limited space in the bow, even if the fish bud capsule is moved back and the four fish bud launch tubes are installed on the ribs of the submarine, it can only be equipped with the first spherical active/passive sonar with a diameter of six meters, so the performance of the "Sailfish" active sonar is not as good as that of the 096 class. Due to the limitation of the internal space of the hull, the "Sailfish" can only carry 22 fish buds and missiles, which is indeed very inferior to the 38 fish 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, and not only is no conventional submarine able to match it, but even the attack nuclear submarines of some second-rate navies are not necessarily much stronger than the "Sailfish." As far as the characteristics of the laws of actual submarine warfare are concerned, perhaps the actual combat performance of the Sailfish is even higher.

Faster, quieter, more aware of the opponent's presence, more detectable of the opponent's position, and more advanced firepower configuration are often the key factors that determine the success or failure of a confrontation between submarines and submarines. The Sailfish has led the industry in quieter numbers. 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 this line of confrontation.

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

The highly automated operating system eliminated the jobs saved by eliminating conventional power equipment, and the number of officers and men of the "Sailfish" was reduced to 36 people, and only eight people were needed to control the entire submarine in normal times. A highly integrated detection, search and fire control system, coupled with a central computer running 250 million times per second, gives the Sailfish the sharpest response speed. In combat, the Sailfish is able to track eight targets while controlling four buds to attack two of the most threatening targets.

Inside this body of steel, I felt an unprecedented pride in my heart. The dream of a strong country is never clearer at this moment. Gu Tianyou deeply knows that the beginning of all this began with his own discovery. Lao Tzu is a person who has made a great contribution to this country!

Don River was still introducing the Sailfish, and that demeanor was like introducing his own son with excellent grades and talent.

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

The "Sailfish" is equipped with the most advanced weapons, especially heavy fish buds.

The new electric fish bud uses a composite battery as the power source, and the range reaches 35 kilometers in 70 knots high-speed mode and 65 kilometers in 45-knot low-speed mode. A thunder head filled with 250 kilograms of high-energy explosives is enough for one fish bud to damage a destroyer, or two fish buds to damage a cruiser, and three fish buds to incapacitate an aircraft carrier. And the accuracy and stability are much higher than the conventional fish buds commonly used today.

In the sailor's cabin, Gu Tianyou and others tasted hot milk tea and pastries with a very bad taste. Don was accompanied by his deputy, who could not be named.

Gu Tianyou said: "I really didn't expect that this trip would be able to go back with this advanced thing." Looking up, Sun Jingfei seemed a little uncomfortable, his brows were tightly knit and his face was pale, and he casually asked what is wrong with you? Sun Jingfei said: "I am a little sensitive to claustrophobic spaces, and it is difficult to restrain them. ”

Don He's deputy codename is Kunpeng, and he is a relatively young major officer, and he can see that he is a little curious about Gu Tianyou and the others. It's just that limited by the rules of this industry, it's hard to say as many words as you want.

As the first mate and assembly chief of this submarine, he is the person who knows this submarine best. Perrin was asking him how long it would take to assemble such a submarine with the current level of industry in the Republic? Kunpeng just smiled, his authority was probably not as big as that of the Don River, so he couldn't be as knowledgeable as the Don River. If he can answer, he will say two words, and if he can't answer, he will smile and not speak.

Perrin is already a prisoner and has never had the opportunity to leave the Republic in his life. Gu Tianyou didn't feel that there were any secrets worth hiding from him. Because the rest of his life will surely be spent in the secret cell of national security. Before boarding the ship, Gu Tianyou had already searched his body carefully, and several miniature electronic devices, including the miniature communicator implanted under the ear door, had been searched, and he should not have the conditions to leak secrets at this time.

Don He motioned for the others to rest, then threw a look at Gu Tianyou, and walked out of the watertight cabin with Kunpeng, Gu Tianyou knew that he had something to say to him alone, and said to Xiaolongnu I went over to take a look, and followed.

In the command room, Kunpeng stood in front of the console, standing with his hands in his hands, staring intently at the uninterrupted and beating numbers of the electronic depth gauge.

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

"Five on the first and ten on the tail, keep the speed. ”

The helmsman first adjusted the index on the depth controller to 330, then adjusted the index on the speed controller, and finally stabilized the steering controller that looked like a car's steering wheel. Next, the automatic control equipment on the submarine adjusts the navigation status of the submarine, without the need for direct control by the helmsman. A submarine with a displacement of several thousand tons is not a car, and it took about a dozen seconds for the submarine to slow down.

The sonar chief kept his hands on the headset, listening very attentively. Adjust the knob of the sonar control panel from time to time and keep your eyes on the sonar screen without blinking. Kunpeng looked at it with concern and asked, "How is it? Did you hear the movement?" The sonar chief shook his head, indicating that no sound had been received.

"I didn't find it, not the best answer, but the worst answer!" Don He's expression was a little solemn. His knife-like face did not show the slightest emotional fluctuation, but his dark eyes flashed with fiery and ferocious emotions. "Three hours ago, we detected a sound reflection in the northwest strait, most likely the Ohio-class submarine of the United States Navy, and the sonar recorded the characteristic noise of the other party, but now we have lost its trace. ”

Gu Tianyou was completely a mallet in this regard, and asked, "If you can't find it, it means that they are gone, isn't this a good thing?"

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

According to Don He's instructions, Gu Tianyou walked into the captain's dormitory next to the command room alone, where a laptop computer had been turned on and placed there, plugged in the USB flash drive, opened it and looked at the contents of it, and couldn't help but be dumbfounded. Sun Mingshen actually let himself find a chance to rescue Pei Lan after landing, and he also wanted to send him to the other countries! As the screen quickly turned into a snowflake, the self-destruction procedure here was indeed activated in time.

This Pei Lan took the initiative to follow, just now Don He told him so many core secrets about this electric submarine, but now Sun Mingshen ordered himself to save this country to the country?
