The spiritual banner of aviation people

Especially hard-working, especially fighting, especially tackling key problems, especially dedication.

The arduous course of developing solid rocket engines in China shows the aerospace spirit of astronauts who are not afraid of difficulties and face difficulties. They have been adhering to the lofty spirit of "national supremacy and striving for first-class" and gradually narrowed the gap with the world's advanced level. Since the beginning of the new century, the scientific research and production of the Fourth Hospital has entered a new stage of leap-forward development. With the progress of science and technology and the enhancement of national strength, the research and production of solid rocket engines have entered the world advanced level, which can be comparable to the world first-class level.
