Military Knowledge: HQ-9 Air Defense system
The HQ-9 (Hóng Qí-9) missile system serves as a central pillar of China’s land-based air defense capabilities. Developed by the China Aerospace Science and Industry Corporation (CASIC) since the 1990s, it offers strategic performance on par with the American MIM-104 Patriot and Russia’s S-300/S-400 systems.
