In modern naval forces, submarines, as strategic platforms, play a vital role. This article will briefly analyze the submarine forces of the Japan Maritime Self-Defense Force and the Chinese Navy, and their respective characteristics and advantages.
The Japan Maritime Self-Defense Force currently has three main types of submarines: the Kinshio-class, the Soryu-class, and the Big Whale class. The Tide-friendly class submarines are known for their good stealth performance and combat capabilities, the Soryu-class is characterized by their advanced sonar system and power plant, and the Big Whale class represents the highest level of Japanese submarine technology, with deeper dives and lower noise levels.
In contrast, the submarine force of the Chinese Navy is mainly composed of Kilo-class submarines of the 636 and 039 series. The Kilo-class 636 submarine is known for its robust double-hull structure and good sonar system, while the 039 series has made significant progress in noise reduction technology, especially in the application of AIP systems.
In terms of submarine sonar systems, Japanese submarines are designed with a focus on all-round detection capabilities, while Chinese submarines have made progress in improving detection range and accuracy. In terms of noise control, the noise level of Japanese submarines is close to that of ocean background noise, while Chinese submarines have effectively reduced noise by applying technologies such as shock-absorbing floating rafts and sound-absorbing tiles.
Overall, the submarines of the Japan Maritime Self-Defense Force have a slight advantage in technology, but they are inferior to the Chinese Navy in numbers. The submarines of the Chinese Navy have reached or approached the world-class level in some technical fields, showing the rapid development of the Chinese Navy in submarine technology.
In the future, with the continuous advancement of technology and changes in strategic needs, the submarine forces of the two navies will continue to develop and improve, providing a solid guarantee for the maritime security of their respective countries. As an important part of the naval force, the development trend and strategic position of submarines will continue to attract attention.
