The
HQ-9 (
红旗; pinyin:
hóng qí, "
red flag" or "
red banner") is China’s new generation
medium- to long-range, active radar homing surface-to-air missile.
Similar to the Russian S-300 and American Patriot systems, the HQ-9 uses a HT-233 PESA radar system. The naval HQ-9 appears to be identical to the land-based variant.
- HQ-9A — Upgraded version, first tested in 1999 and service entry in 2001. Chinese sources claim that the HQ-9 family of systems employ much newer computing technology than imported Russian S-300PMU/PMU1/PMU2 systems, because HQ-9 is developed more than a decade later, thus allowing it to incorporate advancement in microelectronics. Due to the superior computing capability for signal processing, data processing and guidance support, this missile can have an optional semi-active radar homing (SARH) mode, because more info can be processed on board the missile itself.
- HQ-9B — reportedly tested in February 2006. According to Jane's Information Group, this missile has a dual seeker that incorporates both SARH & infrared homing mode.
- HQ-9C - Currently under development, incorporating active radar homing mode.
