As a matter of fact, China can independently develop and manufacture C9 19, and some time ago, it also independently manufactured a large suborbital UAV. Facts speak louder than words, which shows that China's aircraft manufacturing level is really superb. Specifically, China's aircraft manufacturing level is superb because of its strong independent innovation ability, perfect industrial chain and strong mobilization ability. These contents will be explained in detail below:

First, China's aircraft manufacturing level is very high, because China's independent innovation ability is very strong; because aviation manufacturing is a high-end industry, it is impossible for other countries to teach you all the core technologies. If we can't innovate independently, the level of aviation manufacturing will be very limited and can only be maintained at a low level. However, independent innovation is China's advantage. China has absolutely strong national strength to support independent innovation, and a group of outstanding scientists lead independent innovation. Therefore, the level of aircraft manufacturing in China has been greatly improved. China is advanced in both aircraft design and high-tech materials, all because of its strong independent innovation ability.

Secondly, the level of aircraft manufacturing in China is very high, because the industrial chain in China is very complete: every screw and every component of an aircraft can be independently produced and assembled in China, and the complete industrial chain greatly facilitates the aircraft manufacturing industry in China. Even in many countries in the world, the aviation manufacturing industry needs to rely on China's industrial chain. Therefore, China's aircraft manufacturing level is high because China has a complete industrial chain.

Third, China's aircraft manufacturing level is very high, because China's mobilization power is very strong: thanks to the superiority of China's social system and national system, China can concentrate on doing great things. Building an airplane is not a trivial matter, it needs the coordination of many departments and units. In China, it is not only coordinated, but also efficient. It can be seen that the high level of aircraft manufacturing in China is due to its strong mobilization ability.
