5. HQ-9 (China)
Combining components of Russian S-300 technology with domestic innovation, China’s HQ-9 reflects Beijing’s most sophisticated long-range air defence system. Using modern phased array radar for detection and tracking, the system can engage targets at ranges up to 200 kilometres and heights of 30 kilometres. Active radar homing guidance and ability to intercept a variety of targets—from aeroplanes to cruise missiles—allow HQ-9’s missiles Digital signal processing and frequency-hopping features of the system offer strong resilience against electronic warfare. Improved capabilities against ballistic missiles and stealth aircraft are among recent variations.
6. MEADS (Germany/Italy/United States)
Comprising a global effort to produce a highly mobile, flexible air defence system, the Medium Extended Air Defence System (MEADS) In contemporary warfare, its 360-degree coverage and capacity to concurrently fight several threats make it especially useful. Comparatively to conventional PAC-3 interceptors, MEADS employs the PAC-3 MSE missile to offer improved manoeuvrability and range. The open architecture of the system facilitates simple interaction with other air defence systems and upcoming enhancements. For expeditionary operations, its quick deployment capability and capacity to guard moving units make it particularly valuable.
