THAAD can conduct engagements in which atmospheric regimes?

• A. High endo-atmospheric and exo-atmospheric engagements
• B. Low altitude intercepts
• C. Space-based intercepts
• D. Ground-based defense operations

Answer: (A)

THAAD is designed to intercept ballistic missiles during their terminal flight at the upper edge of the atmosphere or just beyond it. That means engagements occur in high endo-atmospheric and exo-atmospheric regimes—the interceptor targets the warhead as it travels through the upper atmosphere or near-space. It isn’t a space-based system, and its capability isn’t focused on low-altitude intercepts. So the best description is those high-altitude regimes, where THAAD’s radar, sensors, and hit-to-kill interceptor are optimized to track and destroy threats.
