Both India and Russia are known for their inefficiency in the construction of military ships. It usually takes three or four years for India to build a large destroyer, while China needs only a year. The situation is even worse in Russia, where the construction of a submarine turned out to be 19 years old. This submarine is a conventionally powered submarine and is considered to have excellent underwater quietness. This submarine is the second boat of the "Lada" class, which is designated "Kronstadt". Construction began in 2005 and it entered service 19 years later.
At the same time, the first Lada-class submarine "St. Petersburg" was rejected by the Russian Navy due to technical problems and was planned to be scrapped and dismantled. Interestingly, China has introduced Russian Kilo-class submarines and rated them well. Therefore, rumors about China's plans to introduce submarines of the "Lada" class have not stopped. However, so far, these rumors have not come true.
China's domestically produced conventionally powered submarines have reached the world's leading level, while the Russian Lada-class submarines have some technical difficulties, especially in terms of the AIP power system. This raises the question: Does China still need to import submarines from Russia? The answer is no. China's domestically produced submarines have adopted the self-developed AIP system, which allows Chinese submarines to have the ability to submerge for a long time, so as to have obvious advantages in concealment and combat capability.
In contrast, Russian submarines have encountered difficulties with the AIP system, which makes their submarine duration relatively short, and their concealment and combat capabilities are somewhat limited. China's domestic submarines have already surpassed Russia in the field of conventional submarines. Not only are they more technologically advanced, but they are also better in terms of performance. The sonar system and equipment of Chinese submarines have reached the world-class level, which makes them have a powerful strike force in maritime operations.
Moreover, the pace of creation of domestic submarines in China is also very fast. According to relevant data, China has already surpassed Russia in the number of submarines built each year. This has allowed China to expand its submarine forces more quickly and improve its maritime capabilities. In addition, the design of China's domestically produced submarines is also more in line with China's actual needs. In contrast, Russian submarines may not be adapted to China's needs in some respects, as they are designed according to Russia's own military needs.
China's domestically produced submarines can better meet the needs of the Chinese Navy and provide better combat results. To sum up, China's domestic submarines have reached the world's leading level, especially in the field of conventional submarines. In contrast, Russian submarines have some technical problems, especially on the AIP system. As a result, China no longer needs to import submarines from Russia. China's domestically produced submarines have the ability to submerge for a long time and have obvious advantages.
Not only are they more technologically advanced, but they are also better in terms of performance and manufacturing speed. Thus, China's domestic submarines have surpassed Russia and become the leader in the creation of submarines in the world.
