China's primary concern regarding THAAD deployment in South Korea is not just about countering North Korean threats but specifically about the powerful AN/TPY-2 X-band radar. China fears that this radar's long-range capabilities could be used to monitor its own military activities, including missile launches and air force movements, deep within its territory. This is perceived as a direct threat to China's strategic security interests and a potential disruption to the regional balance of power, leading to strong diplomatic and economic retaliations.

The AN/TPY-2 X-band radar is the 'eyes' of the THAAD system because it is responsible for detecting, tracking, and providing precise targeting data for incoming ballistic missiles from hundreds of kilometers away. Without this radar, the interceptor missiles cannot effectively engage threats. Recent incidents, such as its reported destruction in Jordan in 2024, highlight its extreme strategic vulnerability. These attacks demonstrate that adversaries recognize the radar as a critical single point of failure for missile defense systems, making it a high-priority target to blind or cripple an opponent's defensive capabilities. This also puts pressure on US defense contractors to speed up production of advanced weaponry, including THAAD interceptors, to replenish strained stockpiles.

A 'layered missile defense strategy' implies using multiple missile defense systems, each designed to intercept threats at different altitudes and phases of flight, to provide comprehensive protection. THAAD's specific role is to intercept short, medium, and intermediate-range ballistic missiles during their terminal phase at high altitudes. This acts as a crucial upper layer of defense. If a lower-tier system like Patriot misses an incoming missile, THAAD provides a second, higher-altitude opportunity to intercept, increasing the probability of success and offering redundancy. This multi-layered approach ensures that a range of missile threats can be addressed effectively, from launch to impact.

THAAD has specific limitations: it is designed exclusively for ballistic missiles, meaning it is not effective against cruise missiles, which fly at lower altitudes and follow different trajectories. While it can counter intermediate-range ballistic missiles, it is generally not intended for very long-range Intercontinental Ballistic Missiles (ICBMs) that fly much higher and faster in their mid-course phase. Additionally, it's not designed for very short-range tactical rockets or artillery. This distinction is crucial because relying solely on THAAD would leave significant gaps in a nation's air defense against a diverse range of modern threats. A comprehensive defense requires integrating various systems to cover different threat types, ranges, and altitudes.

• •Not effective against cruise missiles (different flight profile).
• •Not primarily designed for Intercontinental Ballistic Missiles (ICBMs) (different range and altitude).
• •Not for very short-range tactical rockets or artillery.
