THAAD engagements include intercepts in which atmospheric regimes?

• A. Low Earth Orbit
• B. In-space intercepts
• C. High endo-atmospheric and exo-atmospheric engagements
• D. Subsurface intercepts

Answer: (C)

The main idea is that THAAD is designed to intercept ballistic missiles during their final phase while they’re still in the upper atmosphere or just above it. That places its engagements in high endo-atmospheric and exo-atmospheric regimes. In practice, THAAD targets the warhead as it descends through the upper atmosphere, and can extend to the edge of space, rather than operating in space or below the atmosphere. It doesn’t typically engage in low Earth orbit or subsurface scenarios, which aren’t part of THAAD’s intended intercept envelope.
