Overview
Medium-range Surface-to-Air Missile — the enhanced second block of South Korea's indigenous medium-range air defence system, providing area air defence against aircraft, cruise missiles, and tactical ballistic missiles. The Cheongung II features an improved dual-pulse solid rocket motor for extended range (40+ km) and altitude (20+ km), advanced active radar seeker with enhanced ECCM, and a new fragmentation warhead with proximity and impact fuzing. Guided by the indigenous multifunction 3D phased array radar for target search, tracking, and missile guidance with track-via-missile (TVM) terminal guidance. The system comprises a radar vehicle, command vehicle, and launcher vehicles (each with 6 missile canisters). Cheongung II forms the middle layer of the KAMD architecture between Patriot/L-SAM (upper tier) and short-range systems. Operational since 2020 with ongoing deliveries.
