China’s HQ-9 represents Beijing’s most advanced long-range air defence system, combining elements of Russian S-300 technology with indigenous innovation. The system employs modern phased array radar for detection and tracking, capable of engaging targets at ranges of up to 200 kilometers and altitudes of 30 kilometers. HQ-9’s missiles use active radar homing guidance and can intercept a variety of targets, from aircraft to cruise missiles. The system’s digital signal processing and frequency-hopping capabilities provide strong resilience against electronic warfare. Recent variants have introduced enhanced capabilities against ballistic missiles and stealth aircraft.
