China achieves a breakthrough in shaftless pump spraying technology

According to publicly available information in China, the Type 094 nuclear submarine significantly reduces noise during navigation. This is due to the use of a new and efficient high-temperature gas cooled nuclear reactor, as well as the extensive use of newly designed noise reduction measures, including improved rubber composite sound-absorbing tiles to increase thickness and density of internal inert gas pores, drop off hydraulic shock absorption transmission devices, sound insulation design inside the transmission compartment, plastic coating technology for movable noise sources, damping filling material technology for the main transmission shaft hole, high-precision propellers, and the ability to open and close the main drainage hole.
Although the noise of 094 has decreased significantly, there is still a gap between the United States and Russia. According to data, the noise level of the American Sea Wolf class during low-speed navigation is only about 95 decibels, almost blending in with the 90 decibel sound of the ocean itself. It is extremely difficult to detect and is currently the world's quietest nuclear submarine. The God of the North Wind in Russia is 100 decibels. But whether it's the American Sea Wolf class nuclear submarine or the Russian North Wind God class nuclear submarine, they all use shaft pump jet propulsion technology.According to relevant information previously disclosed by the US military, the Type 095 attack nuclear submarine adopts a shaftless pumping and spraying technology that even US attack nuclear submarines do not use, so that in terms of the submarine's ability to conceal in the deep sea, the Type 095 is stronger than many US submarines.According to this statement, the 095 may replace the Sea Wolf class and become the quietest nuclear submarine in the world. The 096 also adopts shaftless pumping technology, which will officially elevate China's sea based nuclear deterrence to the world's top level, even surpassing the US Ohio class ballistic missile submarines. Military experts say that before the latest Columbia class nuclear submarine in the United States becomes combat ready, China's Type 096 nuclear submarine will become the world's top level nuclear submarine, just like Russia's "God of the North Wind" nuclear submarine.
By 2021, the US military's shaftless pump spraying technology had not yet been developed. However, China's breakthrough was already four years ago. In terms of China's research efficiency and construction efficiency, this may mean that China has applied these technologies in large quantities to underwater combat units. This could cause unimaginable damage to the US fleet in the future when China and the United States may engage in underwater combat in the Pacific.
