A THAAD battery has how many modes of engagement and what are they?

• A. 2 modes: Automatic and Semi-Automatic Modes
• B. 3 modes: Manual, Automatic, Semi-Automatic
• C. 2 modes: Manual and Automatic
• D. 1 mode: Automatic

Answer: (A)

Engagement modes describe how much control is used to intercept a threat. A THAAD battery operates in two modes. In Automatic mode, the system handles detection, threat assessment, intercept planning, and launch automatically once the engagement criteria are met, providing the quickest response. In Semi-Automatic mode, the system still performs the necessary processing, but a human operator must authorize the intercept before launch, adding an oversight step. Fully manual control isn’t part of the standard THAAD engagement flow in this context, as the design emphasizes rapid automated response with an option for operator approval. So, the two modes are Automatic and Semi-Automatic.
