The question of whether China can eliminate all Russian-made fighters within 10 years is a complex and uncertain topic about the continuous mass production of the J-20. Here's my analysis:
First of all, as a fifth-generation stealth fighter independently developed by China, the J-20 has obvious advantages in performance and technical level compared with Russian-made fighters. The J-20 has higher stealth performance, faster speed and longer range, as well as outstanding advantages in information-based operations. With the continuous mass production and service of the J-20, the combat capability of the Chinese Air Force will be significantly improved.
Second, the Chinese Air Force has begun to modernize, upgrade and transform, from the traditional territorial air defense type to the offensive and defensive type. In this process, the elimination of old Russian-made fighters is an inevitable choice. China's Air Force has begun to gradually replace Russian-made fighters, such as introducing and improving Su-35 fighters, and developing and producing new fighters such as the J-16 on its own.
However, it will not be easy to eliminate all Russian-made fighters within 10 years. On the one hand, Russian-made fighters still occupy a certain proportion of China's air force, and their technical level and combat capability cannot be ignored. On the other hand, the upgrading of the equipment of the Chinese Air Force needs to take into account many factors such as economic costs, technical reserves, and personnel training. In addition, changes in the international political and military situation may also have an impact on the plans.
To sum up, the continuous mass production of the J-20 provides strong support for the modernization and upgrading of the Chinese Air Force, but it is not easy to eliminate all Russian-made fighters. This requires China to make sustained efforts in upgrading equipment and personnel training, and at the same time, it also needs to take into account the influence of various internal and external factors. Therefore, we cannot simply give a positive or negative answer to this question, but need to analyze and judge according to the actual situation.
