Recently, Xinhua Net publicly reported that the South China Sea Fleet was listed as a three-type main battleship at one time! Among them is a Type 094A strategic nuclear submarine, and military fans are very excited for a while! Why?
It turns out that China has always been a new generation of strategic nuclear submarines after they are launched into service, and the previous generation of nuclear submarines will be officially unveiled. Since the 094A has been publicly unveiled, it means that the Type 096 strategic nuclear submarine has been launched. As for why the Type 096 strategic nuclear submarine was launched, the 094A strategic nuclear submarine has just entered service?
Type 096 strategic nuclear submarine scenario map
The reason is also very simple, on the one hand, the displacement of the Type 094A strategic nuclear submarine is much smaller and the cost is lower than that of the Type 096 strategic nuclear submarine, on the other hand, the nuclear submarine construction cycle is very long, and it will go through 1-2 years of sea trials after launching. Although the Type 096 strategic nuclear submarine is more advanced, it needs to undergo a long-term sea test after launching, and the improvement is insufficient, and the reliability can be improved to form combat effectiveness. Therefore, although the Type 096 strategic nuclear submarine has been launched, it is necessary to continue to build the Type 094A strategic nuclear submarine, a technologically mature nuclear submarine, as a transition, in order to ensure that the underwater nuclear counterattack force is reliable enough.
At present, China's all-electric propulsion system and shaftless pump spraying technology have been successfully developed for many years and are mature enough. It is expected that the Type 096 strategic nuclear submarine will be adopted, the noise level will be further reduced, and the noise level will lead the world! In addition, the size of the Type 096 strategic nuclear submarine will be further increased to accommodate a larger and more powerful JL-3 submarine-launched INTERCONTINENTAL missile.
Although the Type 096 strategic nuclear submarine is more advanced, the Type 094A strategic nuclear submarine is not bad, at least better than many people estimate, including one of the most important indicators of noise level.
As we all know, because the industrial level was too poor, although China built nuclear submarines with its own capabilities, the noise of China's first generation of nuclear submarines was amazing. So much so that the U.S. Navy once ridiculed China's nuclear submarines as if they were tractors, and as soon as China's nuclear submarines were turned on, the U.S. military monitoring in Hawaii could hear them.
In 1974, China's newly built Type 091 nuclear submarine is indeed only to solve the problem, the noise level is indeed amazing, it is estimated that the noise level of the Type 091 nuclear submarine is as high as 160 decibels. Fortunately, after solving the problem, it is much easier to improve and upgrade. China quickly through the iteration of technology caused the 091, 092 type nuclear submarines to improve the model, the noise was greatly reduced, once in the 1996 Taiwan Strait crisis to show its might, successfully forced back the opponent.
Type 092 strategic nuclear submarine
With the unremitting efforts of China's scientific researchers and the advent of China's second-generation nuclear submarines, the noise level of China's nuclear submarines has once again been greatly reduced.
The Type 094 strategic missile nuclear submarine is the second generation of strategic missile nuclear submarine independently developed by China, with a length of 133 meters, a width of 13 meters, an underwater displacement of about 11,000 tons, and 12 giant wave 2 submarine-launched intercontinental missiles. The overall design of the Type 094A strategic nuclear submarine is basically the same as that of the Type 094 strategic nuclear submarine, and the biggest difference is that the "turtle back" is higher in order to carry a larger and more powerful Giant Wave 2 improved intercontinental missile.
On April 21, 2017, an article entitled "Listening to Thunder in the Silence - Remembering the Team of Zhang Jinlan, the first prize winner of the 2016 National Science and Technology Progress Award and the chief division of a certain type of nuclear submarine in China", revealed the key technologies used by a large number of Type 094 strategic nuclear submarines, which directly confirmed that the noise level of the Type 094 strategic nuclear submarine was greatly reduced while the safety was greatly improved, and the combat effectiveness was also greatly improved. Military experts estimate that its overall noise level will reach 105 to 110 decibels, close to the level of the most advanced nuclear submarine in the United States. It is expected that the noise of the Type 094A strategic nuclear submarine is also at this level, but the combat effectiveness is stronger.
<h1 class="pgc-h-arrow-right" data-track="6" > so what new technology is used in the Type 094A/094 strategic nuclear submarine? How has the performance improved? (Today's headline "detailed technology" produced, infringement must be investigated)</h1>
"Listening to Thunder in silence - Remembering the first prize winner of the 2016 National Science and Technology Progress Award and the chief division team of a certain type of nuclear submarine of the second generation in China" This article reveals that the various innovations of China's second generation 094 nuclear submarines are summarized as four major leaps. First, it solves the single and double shell structure with large size, large depth, dense and large row of holes. The second is the use of natural circulating pressurized water reactors. Third, the use of new shock absorbers, sound-deadwave technology. Fourth, it is equipped with a new submarine-launched intercontinental missile, and its range and power have been greatly improved.
Type 094 strategic nuclear submarine
Specifically, these four key new technologies have been applied.
1. The mixed structure of single and double shells is adopted to reduce the dead weight and also take into account the advantages of strong anti-damage ability of double shells.
As we all know, the nuclear submarines of the United States, Britain and France use a single-hull structure, and the ability to resist damage is weak, but the advantage is that the structure has a lower dead weight and more space. The Soviet nuclear submarines adopted a double-hull structure, which had the advantage of strong anti-damage ability, but the disadvantage was that it was too bulky and occupied the internal space.
China's first generation of nuclear submarines, like the Soviet Union, adopted a double-hull structure, which directly led to the small internal space of the submarine and the heavy weight of death. In order to take into account the survivability, reduce the dead weight, and improve the internal space of the submarine, the 094A/094 strategic nuclear submarine adopts a single and double hull hybrid structure, and the critical compartment uses a double hull, which can improve the ability to resist damage, and the non-critical compartment uses a single hull, which can reduce the structural dead weight and improve the utilization rate of submarine space.
2. The "three-circuit" integrated natural circulation nuclear reactor is adopted, which is more efficient and the noise is greatly reduced.
It is understood that the submarine nuclear reactor coolant pump is one of the main sources of nuclear submarine operating noise, if the nuclear reactor does not need a coolant pump, it can fundamentally eliminate the noise source. European and American countries took the lead in developing nuclear reactors for submarines that do not require coolant pumps, which are natural circulation nuclear reactors. Later, After arduous technical research, China's scientific researchers also developed such reactors, which greatly reduced the noise level of strategic nuclear submarines.
The most proud thing is that compared with the integrated self-circulating nuclear reactors in Europe and the United States using a double circuit, China's 094A/094 strategic nuclear submarine integrated self-circulation nuclear reactor adopts a three-circuit design. Without the use of the main pump, it is guaranteed to take away the heat of the reactor in any situation and eliminate the noise of the main pump operation. Not only greatly improve the safety of nuclear reactors, greatly reduce the noise of nuclear reactor operation, but also the operation efficiency of nuclear reactors is higher!
3. Using floating raft shock absorption technology and anechoic tile technology, the noise is reduced by 40 decibels.
According to reports, the US Navy began to study floating raft shock absorption technology in the 1960s, achieved results in the 1980s, and led the world in its nuclear submarines, reducing noise by 15 to 20 decibels. China followed up on the study of this technology and reached the stage of practical application in the 1990s. According to official reports, the first Type 094 strategic nuclear submarine in 2006 is expected to adopt this technology, and the later 094A/094 strategic nuclear submarine has no reason not to use it. That is to say, with this technology alone, the 094A/094 strategic nuclear submarine can reduce noise by 15 to 20 decibels!
In addition to floating raft damping technology, silenced tile technology can also greatly reduce noise. According to US media reports, the US research team found that a single layer of silenced tiles can reduce noise by 25 decibels, and double-layer anechoic tiles can reduce about 40 decibels. The Type 094A/094 strategic nuclear submarine has adopted sound-deadwave technology, which is expected to reduce noise by about 25 decibels.
These two technologies are expected to reduce noise by at least 40 decibels, coupled with the noise reduction effect brought by the "integrated natural circulation nuclear reactor", it is expected that the noise level of the 094A/094 strategic nuclear submarine will be reduced by 50-55 decibels compared with the 091 nuclear submarine, and the noise level can reach 105-110 decibels!
4. It is equipped with the JL-2 improved intercontinental missile, and its comprehensive performance is equal to that of similar missiles in the United States and Russia.
Official information about submarine-launched ICBM missiles
According to the description of the official report, "the comprehensive performance of the first rocket has reached the international advanced level, and it has appeared in the 70th anniversary of the National Day military parade...", the rocket mentioned here is the JL2 intercontinental missile unveiled at the 2019 National Day parade.
So what is the international advanced level of submarine-launched intercontinental missiles?
Take, for example, France's M51 submarine-launched intercontinental missile. The M51 can carry 6 to 12 nuclear warheads. The power of the nuclear warhead is 100,000 to 150,000 tons, and the range is about 13,000 kilometers.
At the end of the last century, the top level of the US military learned through spies about the miniaturization level of nuclear weapons in Our country and the United States, and they were immediately shocked and even suspected that Chinese Scientists in the United States had leaked secrets. To this end, he directed himself and acted in the "Li Wenhe Espionage Case", and later because he could not find any evidence, he could only be rehabilitated. This incident proves that the level of miniaturization of nuclear weapons in our country is comparable to that of the United States!
The JL 2 submarine-launched ICBM is 2 meters in diameter and 14 meters long, and the total weight of the launch is more than 50 tons, and the improved version of the JL 2 will only be longer and heavier! In order to load it, the Type 094A strategic nuclear submarine will further increase the turtleback height on the basis of the Type 094 strategic nuclear submarine. Therefore, according to common sense, the comprehensive performance of the JL-2 improved ICBM is at least comparable to that of the French M51 ICBM!
JL-2 submarine-launched INTERCONTINENTAL missile
That is to say, the JL-2 improved INTERCONTINENTAL missile can also carry 6 to 12 nuclear warheads, but due to the higher level of miniaturization, the explosive yield of each warhead can reach the level of the United States, that is, the level of 300,000 to 475,000 tons. According to the calculation of carrying 12 JL-2 improved intercontinental missiles, a Type 094A strategic nuclear submarine can launch 60 to 120 nuclear warheads, which is enough to destroy a medium-sized power! Even superpowers are hard to resist the attack of the Type 094A strategic nuclear submarine!
Of course, the Type 094A strategic nuclear submarine is not perfect, and there are many shortcomings that cannot be ignored! Mainly these three points:
1. The turtle's back is too obvious, which increases the sailing resistance and affects the speed increase.
2. The number of submarine-launched intercontinental missiles on board is still too small, only 12.
3. The diameter of the hull is expected to be only 9.5 meters, which is still too small, limiting the size and power of the missile.
Although the 094A still has many shortcomings, and the overall performance is still inferior to the Ohio-class strategic missile nuclear submarines entered service by the United States in the 1980s, with the world-class JL2 improved intercontinental missile, it is enough to hammer any enemy country!
What do you think about that? Welcome to discuss.
