In addition, China's national defense science and technology is far behind, and it is not very active in the research, development and procurement of new weapons. There is also a big gap in national defense education. Many national defense science and technology researchers have never thought about it when they entered this department, nor have they been educated and instructed to actively research and develop. This is a big problem. If this problem is solved, everything will be easy. Catch up with Russia, at least there is hope!
