Recently, Xinhuanet publicly reported that the South China Sea Fleet was listed as a Type 3 main combat ship at one time! This includes a Type 094A strategic nuclear submarine, a news that has thrilled military fans. However, this raises the question: why will the previous generation of nuclear submarines be officially unveiled after the new generation of nuclear submarines enter service? The reason is not complicated, it involves the complex process of technological maturity, performance improvement and military readiness of nuclear submarines. This article will explain why the Type 094A strategic nuclear submarine entered service after the launch of the Type 096 strategic nuclear submarine and explore their key technological innovations, how to improve noise levels, and how to increase the reliability of nuclear counterattack forces.
The mainland has always adopted an orderly renewal strategy, that is, the previous generation of nuclear submarines will be officially unveiled after the new generation of nuclear submarines are put into service. Thus, the Type 096 strategic nuclear submarine has been launched, and the Type 094A strategic nuclear submarine has entered service. There are two main reasons behind this order. First of all, the Type 094A strategic nuclear submarines have a smaller displacement and lower cost than the Type 096 strategic nuclear submarines, which makes them more economical to a certain extent. Secondly, the construction period of nuclear submarines is quite long, and after launching, they need to undergo 1-2 years of sea trials to improve deficiencies and increase reliability, and finally form combat effectiveness. Thus, while the Type 096 strategic nuclear submarine is more advanced, it will take more time to reach service standards. In order to ensure the reliability of the underwater nuclear counterattack force, we continue to build Type 094A strategic nuclear submarines as a transition and backup.
At present, Continental's all-electric propulsion system and shaftless pump injection technology have been successfully developed for many years and are quite mature. The application of these technologies will allow the noise level of the Type 096 strategic nuclear submarine to be further reduced, ahead of other nuclear submarines in the world. In addition, the size of the Type 096 strategic nuclear submarine will be further increased to accommodate more and more powerful Julang-3 submarine-launched intercontinental missiles. Although the Type 096 strategic nuclear submarine is more advanced, the Type 094A strategic nuclear submarine is not inferior, especially in key performance aspects such as noise levels.
In the past, the mainland's first-generation nuclear submarines were ridiculed by the U.S. Navy as "tractors" because of their limited industrial level and very high noise levels, because once activated, their noise could be picked up by U.S. listening devices as far away as Hawaii. However, with the continuous improvement and upgrading of technology, the noise level of nuclear submarines on the mainland has been significantly reduced. Taking the mainland's first-generation nuclear submarine Type 091 as an example, its noise level was as high as 160 decibels, but through technological iteration and improvement, the noise level of subsequent models such as Type 092 was significantly reduced, and even showed excellent performance in the 1996 Taiwan Strait crisis, successfully forcing back opponents.
With the unremitting efforts of scientific researchers, the noise level of the mainland's second-generation nuclear submarines has once again been significantly reduced. The Type 094 strategic missile submarine is a second-generation strategic missile nuclear submarine independently developed by the mainland, which adopts a number of key technological innovations. Among them, the key technologies adopted by the Type 094A strategic nuclear submarine directly confirm that the noise level has been greatly reduced, the safety has been improved, and the combat effectiveness has been greatly improved. This technology makes the overall noise level of the Type 094A strategic nuclear submarine reach 105~110 decibels, which is close to or even ahead of the level of the most advanced nuclear submarine in the United States. Therefore, although the Type 096 strategic nuclear submarine has been launched, the noise level of the Type 094A strategic nuclear submarine is also at a similar level, and its combat effectiveness is much stronger.
So what new technologies are used in the Type 094A/094 strategic nuclear submarines, and what are the performance improvements? An article titled "Listening to Thunder in a Silent Place - Remembering the Team of Zhang Jinlan, the First Prize Winner of the 2016 National Science and Technology Progress Award and the Chief Engineer of China's Second-Generation Nuclear Submarine", revealed many details of key technologies. First of all, a single-double-shell hybrid structure is adopted to take into account the reduction of dead weight and the improvement of damage resistance. This structure allows the nuclear submarine to strike a balance in the utilization of internal space, avoiding the disadvantage of being too bulky. secondly
The Type 094A/094 strategic nuclear submarine uses a natural circulation pressurized water reactor, which significantly reduces noise levels compared to the coolant pumps of conventional nuclear submarines. This is because the coolant pump of the nuclear reactor of a nuclear submarine has always been one of the main sources of noise. Natural cycle nuclear reactors eliminate this problem and make the operation of nuclear reactors quieter. Not only that, the Type 094A/094 strategic nuclear submarine adopts a three-circuit design, which can effectively take away the heat of the nuclear reactor without the need for a main pump. This not only improves the safety of the nuclear reactor, but also reduces the noise level during operation, while also increasing the efficiency of the nuclear reactor.
In addition, floating raft damping technology and acoustic tile technology are also widely used, effectively reducing the noise level by up to 40 decibels. Floating raft damping technology was first researched and applied to nuclear submarines by the United States in the 80s, effectively reducing noise levels. Continental then followed up with research and realized practical application in the 90s of the last century. The adoption of this technology means that the noise level can be reduced by 15~20 decibels for the Type 094A/094 strategic nuclear submarine.
In summary, the performance of the Type 094A/094 strategic nuclear submarine has been significantly improved. Through the adoption of new technologies such as single-double-hull hybrid structures, natural circulation nuclear reactors, floating raft damping technology and sound-absorbing tile technology, noise levels have been significantly reduced, safety has been improved, and combat effectiveness has been enhanced. This makes the Type 094A/094 strategic nuclear submarine a powerful nuclear counterattack force and achieves a prominent position in the international nuclear submarine competition.
In the future, the development of nuclear submarines on the mainland will continue to advance, not only in terms of technology, but also in terms of quantity and quality. This will help consolidate the country's nuclear strategic deterrent while maintaining the country's security and stability. Driven by continuous scientific research and technological progress, China's nuclear submarines will continue to achieve even greater achievements in the future. This is also an important aspect of the mainland's continuous enhancement of its national defense strength and its contribution to the maintenance of peace and stability in the international situation.
