The Type 912 "Beluga-class" nuclear-powered attack submarine is one of China's key projects during the "Navy Holiday" period.
At the same time, it is also the top priority development project of the Chinese Navy.
The reason is that the hull height of the submarine is very low and can be built secretly in sealed docks and cave bases.
Just like the situation at the Bohai Shipyard, even if it returns to port for supply and maintenance For repairs and renovations, they can also be driven directly into cave bases or enclosed shipyards.
They are not as eye-catching as large surface ships and cannot be hidden.
Especially big toys like battleships are like shining stars.
Not to mention officially entering service, even if they are still in the dock, they will attract a lot of attention and attract countless eyes.
Well, while building nuclear submarines, the battleships were renovated with great fanfare in the Bohai Shipyard for this reason.
With the Hou Yi, which is as dazzling as a firefly on a summer night, attracting hatred, no, attracting attention, the construction of the Beluga-class is much safer, which is to take advantage of the principle of "darkness under the light".
The "Beluga-class" attack submarine has a total length of 110 meters, a width of 10.5 meters, a draft of 9.9 meters when sailing on the water, a surface displacement of 6,300 tons, an underwater displacement of 7,200 tons, and a maximum diving depth of 500 meters.
The main weapon system of this class of submarines is six 600mm heavy-duty torpedo launch tubes arranged on both sides of the middle hull, equipped with 40 "Fish IV" hybrid guided torpedoes for submarines.
In addition, the torpedo launch tube of this class of boats can not only launch torpedoes, but also launch "Fire Dragon 2B" submarine-launched anti-ship cruise missiles and "Flying Thunder" submarine-launched anti-aircraft missiles at a depth of 50 meters.
In addition, it also has the ability to lay mines, and can carry 100 to 180 mines for mine laying operations.
In addition, a folding 20mm rapid-fire cannon is integrated into its snorkel.
The Beluga-class power system is a fourth-generation air-cooled fast reactor, two submarine steam turbines with an output of 30,000 kilowatts, and an auxiliary propulsion motor with a power of 400 kilowatts.
Single-shaft propulsion, seven-blade high-angle propeller, top speed on water is 20 knots, and top speed underwater is up to 35 knots.
In other words, if it wants to run away, basically not many destroyers can catch it.
It is not just a simple nuclear submarine, but the highest-tech product integrating all of China's black technologies.
Snorkel, sea-to-air search radar and integrated electronic support system, buoy antenna, etc.
It is even equipped with an air-to-air radar and a quadruple lift-type semi-active air-to-air missile launch tower with a range of 10 kilometers.
There are also equipment such as bow spherical array sonar, hull-adaptive active sonar, hull passive sonar array, towed sonar, audio decoys and other equipment that combine the best of more than ten years of acoustic laboratory technology.
There are also multiple tactics, fire control, voiceprint analysis and processing and navigation computers that are combined with a 32-bit computer as the core.
The degree of automation is quite high.
It can almost be regarded as a submarine from the late 1960s to the mid-1970s in the original time and space.
When it comes to certain individual projects, such as information collection and processing capabilities, torpedo technology, submarine-launched missiles and fire control capabilities, they can even reach the level of the 1980s or 1990s.
The "Fish Type 4" torpedo used by the Beluga class is the latest and most advanced heavy-duty anti-ship torpedo.
It is an upgraded version of the Fish Type 2 wire-guided passive acoustic torpedo.
It uses a more advanced hybrid guidance, that is, a wire-guided main torpedo.
Passive acoustic guidance wake guidance.
In particular, an advanced computer processing system is adopted, which gives it certain intelligent functions.
Not only can it automatically track, but it can also be controlled by human intervention to avoid baits.
It can also set navigation points to allow the torpedo to make a low-speed detour and sneak attack to avoid leakage.
Submarine position.
The Fish IV torpedo can be used against both ships and anti-submarines.
Due to the use of a new type of oxygen-rich fuel, it has the characteristics of high energy density, low noise, and no wake.
And the range and speed are very impressive.
The range is 50 kilometers at 40 knots and 38 kilometers at 55 knots.
The warhead weighs 300 kilograms and can be launched by an air turbine pump at a water depth of 900 meters.
By the way, the torpedo warhead explosive currently used in China is a high-power aluminum powder mixed explosive developed by a group of pyrotechnics experts from the Institute of Chemistry.
According to tests, its power is 1.52 times that of China.
A single mine hit can sink a large submarine or cruiser-level surface ship, and three to four torpedoes can sink the latest foreign battleships.
You get what you pay for.
Since this Fish Type 4 torpedo is so formidable, it is very expensive.
One piece costs more than 50,000 Chinese dollars, which is twice as much as the Fish Type 2 torpedo.
By the way, according to Wen Desi's order, all weapons of the Chinese People's Liberation Army, except nuclear weapons and strategic missiles, including torpedoes, missiles and other weapons, once developed, must be subject to no less than 100 test firings for verification.

Reliability, the reliability needs to be above 95 to be considered qualified.
If you can't reach it, keep improving and keep shooting until you reach the target.
Therefore, China's various types of torpedoes are extremely reliable.
It just doesn't matter if they can't hit them.
There are none that won't explode once they hit.
This is very different from the deceptive version of torpedoes used by the United States and Germany during World War II in the original time and space.
For example, during World War II in the United States in the original time and space, a certain submarine achieved the miracle of hitting 14 torpedoes in a row without any explosion.
Afterwards, the Japanese merchant ship found that its belly was full of torpedoes, but it didn't explode.
The unlucky American captain almost died of anger.
Of course, the result of this is that the cost of China's weapons development is very high, but Wen Desi knows very well that the money is worth spending.
As long as one more ship is sunk, a few more bombers are shot down, and one less ship is sunk or a few less aircraft are lost, the extra money spent will be returned.
Anyway, China in this plane has a complete technology tree for future generations.
You can directly light up the technology tree in sequence according to the correct path, and choose important key technologies for development.
There is no need to take detours, and you are not afraid of clicking on the wrong technology tree, so you don't have to make mistakes.
The technology tree wastes a lot of money and time, and the money that can be saved at this point is much cheaper than shooting hundreds or thousands of rounds at target practice.
The fire control system of the Beluga-class submarine can control 6 torpedoes at the same time.
This is not because the computer can do multiple tasks in a time-sharing manner, but by using the stupidest method.
Each torpedo tube is equipped with a fire control computer and operating console. , once a torpedo is fired, it will be monitored by a dedicated operating console until the wire is cut off.
Six operating consoles can control six torpedoes at the same time.
Beluga-class attack submarines usually carry 40 torpedoes.
The general configuration plan is: 14 standard Yusi-type torpedoes, mainly used to attack heavy ships.
There are 20 Yusi Type B torpedoes that attack merchant ships, submarines and small and medium-sized ships.
This is a medium-sized torpedo that weighs only 800 kilograms, has a range only half that of Type A, and has a warhead reduced to 250 kilograms.
Four Fish Type C pod-type timed torpedoes, also known as "fish mines", are Type B wrapped in a shell with an electric engine.
After being fired from the torpedo tube, they can sail at a low speed of 10 knots for up to 30 kilometers. , then float in the water or sit on the bottom, and start the torpedo to automatically circle around to search and track the mine-like model according to the set time.
Finally, there are 2 Yusidian torpedoes.
This is a model equipped with a tactical nuclear warhead.
It is the world's first nuclear torpedo.
Its yield can be freely selected between 10,250 tons.
Of course, if you launch a nuclear torpedo, there is a minimum range limit, otherwise it will blow up and sink yourself, causing an own incident with a hit rate of 200.
In addition to torpedoes, it also carries 6 "Fire Dragon 2B" submarine-launched anti-ship cruise missiles and 8 "Flying Thunder" air defense missiles.
However, compared to the terrifyingly powerful Yu-4 torpedo, the "Fire Dragon 2-B" submarine-launched anti-ship cruise missile is not so powerful.
After all, it is launched from a torpedo launch tube and has a limited volume.
Two to three Fire Dragon 2B-type cruise missiles can ensure the sinking of ships below light cruisers, and can also cause serious damage to aircraft carriers and heavy cruisers.
However, they are somewhat powerless against thick-skinned things like battleships, and destroying the superstructure is still not possible.
Okay, it would be very difficult to sink.
Of course, this configuration plan can be changed.
If you are performing a break-up mission, bring most of the Yu-4B type nuclear torpedoes; if you are desperate and want to fight, just bring all the Yu-4-D nuclear torpedoes.
You can also not carry any torpedoes, replace them all with missiles, and pretend to be a cruise missile submarine.
You can also bring all the mines with you to lay mines.
In addition, the Beluga class can be reloaded immediately after firing the torpedo.
Due to the improvement of the servo mechanism, the reloading time of a single torpedo is shortened to 2 minutes.
The torpedo cabins on both sides can be loaded with three torpedoes in each cabin within 6 minutes.
However, in order to launch again, the wire from which the torpedo was previously launched must be cut off.
In other words, the performance of the Beluga-class attack submarine is already very complete, and it has basically everything that a nuclear submarine should have.

Moreover, the Beluga-class is just the beginning, and the design of a newer model, larger displacement, and more powerful cruise missile attack submarine has been completed.
The "strategic missile submarine" known as the biggest trump card and the ultimate deterrent force has now completed most of the technical demonstrations.
The supporting "Julang 1" ballistic missile has also completed all tests and is building a production line, just waiting for mass production.
April 7, 1931, AD 2772, on the surface of the Sea of Whales in Japan.
The Sea of Whales is also the Sea of Japan.
In fact, the name Sea of Japan appeared very late.
It was named by the Russian voyager Crussensted in 1815.
Before that, "Sea of Whale River" was the name here.
In the original time and space, because China had lost its status as a coastal country, any name had no meaning.
In this dimension, after regaining the lost territory, China once again became a coastal country of the Whale Sea, and it is currently one of the only two coastal countries and the largest coastal country, so it will naturally restore its original name of Whale Sea.
And not only has the name "Sea of Whales" been restored on China's maps, but as China's international status has improved and its voice has increased, other countries have also begun to change it, and the name of this sea has gradually changed back to its original name on foreign maps.
The "Sea of Whales".
The temperature of the Whale Sea is still relatively low in April, and a layer of gauze-like sea fog covers the sea surface, making everything in sight hazy.
At this time, the fog on the sea surface stirred violently, and two "Chongqing-class" destroyers rushed out.
This is a treaty-type destroyer finalized by China in 1928.
Production began in the same year to replace the Zhuhai-class destroyers that were in service before World War I.
Because the design of the Zhuhai-class destroyer was very successful and was perfect during World War I, no new destroyers have been designed since then.
It was not until the signing of the Washington Naval Treaty that due to the intrigues of the great powers, the treaty's provisions for destroyers reached an unprecedented 3,000 tons.
Therefore, China also felt that the original Zhuhai class was outdated and the ship was aging, so it began to launch new destroyers.
Construction plan.
The Navy originally planned to start upgrading the destroyers in 1922, but due to President Wen's intervention, it was delayed until 1928 to complete the finalization.
This was because of the problem of supporting subsystems.
The "Chongqing-class" destroyer is a new type of ship designed only in 1928.
Its power naturally uses the latest rc05 series gas turbine.
This class of destroyers is powered by a combination of gas and electricity, and is fully electric driven.
It uses four rc0520 gas turbines as power to drive the generator, and then uses the electric drive motor to drive the propeller.
The total output is 80,000 kilowatts, dual-shaft drive, top speed of 36 knots, and endurance of 20 knots and 4,500 nautical miles.
Although the Chongqing class is a treaty destroyer, everyone knows that it is abnormal not to play with the scales these days.
Therefore, the standard discharge of Chongqing class claims to be 2950 tons, but it is actually 3500 tons, with a full discharge of 4100 tons.
The Chongqing class is equipped with three twin-mounted latest 55-caliber 130mm high-level and flat dual-purpose guns, with an effective range of 27 kilometers, a maximum firing height of 18,000 meters, and a rate of fire of up to 20 rounds per minute.
The secondary battery consists of four twin 75mm 55-caliber high-level and flat-surface dual-purpose cannons, four twin-mounted 65-caliber 40mm high-level and flat-surface dual-purpose cannons, and two twin-mounted 20mm cannons.
The anti-aircraft firepower is very powerful.
There are also two quadruple 600mm torpedo tubes. 2 12-tube anti-submarine rocket depth bomb launchers and 4 anti-submarine mortars.
Oh, its weapons also have epoch-making products, including an experimental 8-unit "Haihongqi Type 1" anti-aircraft rocket, er, a guided rocket.
This shows that the Chongqing class is China's last artillery destroyer.
Not far behind the two Chongqing-class destroyers, a large warship painted in blue and white marine camouflage gradually appeared in the sea fog.
Its speed at this time was not much slower than the Chongqing-class destroyers, at least 35 knots.
In the bridge of the ship, Director Li said very happily: "The Shandong aircraft carrier is indeed our latest aircraft carrier.
It can sail continuously for 8 hours at a top speed of 35 knots without any abnormality.
The only pity is that it was restricted by the treaty Due to restrictions, we cannot make it bigger.
Such a good ship is not as big as the Liaoning class."
Captain Gu Lu said in a low voice: "Director Li, 40,000 tons is not a small amount, we only reported 35,000 tons."
This time, Director Li personally accompanied the Shandong on a lap of the North Pacific.
Starting from Qingdao, he went to Ryukyu and the Ogasawara Islands, and then went north around the Japanese archipelago until he reached the Bering Strait and then along the Kamchatka Peninsula of Ice and Fire.
The peninsula goes south, then enters the Shao Sea, the ancient name of the Sea of Okhotsk, and then goes south from the Andong Strait to the Tatar Strait and enters the Whale Sea.

Along the way, the Shandong spent most of the time at a high speed of more than 30 knots without stopping at any time.
All the escort ships that followed it when it set sail were dragged to death because they did not have the abnormal endurance of the boss.
Fortunately, the navy also anticipated the situation, so it adopted a relay escort.
At present, these bodyguards are all transferred from the Orca Bay Single Crown Bay Base of the North Pacific Squadron.
At this time, the communications staff officer ran over and said to the captain: "Report, there is a call from the Dandong saying that there is no smoke coming out of our chimney."
Yes, even though the aircraft carrier was racing at top speed just now, there was no smoke coming out of its chimney. "" Gu Lu was embarrassed and quickly ordered: "Slow down quickly, bastard, what's going on over there in the boiler room?
Why is there suddenly no smoke?"
Li Ang said speechlessly: "Check quickly to see if the combustion device has malfunctioned.
Fortunately, there are no foreign ships nearby, otherwise it will be exposed."
That's right, the Shandong is a nuclear-powered aircraft carrier, so it was so fortified that it exhausted two groups of bodyguards.
It is still in the sea trial stage.
However, nuclear power is still a secret, so the current Shandong still has to install a chimney on the starboard side to deceive the enemy.
It usually burns heavy oil and emits smoke to deceive people and disguise itself as a nuclear-powered ship
