How does the THAAD TPY-2 search area?

• A. It scans the entire sky continuously
• B. It relies on external guidance with no internal search plan
• C. It uses intel on BMOAs to develop a battle plan with search fences
• D. It tracks only predetermined trajectories

Answer: (C)

TPY-2’s search area is shaped by intelligence about where ballistic missiles are most likely to appear. Rather than sweeping the entire sky, the radar is directed to a battle plan that divides the coverage into search fences—sectors the radar monitors to detect and cue potential threats. This approach focuses sensing power on the most probable threat corridors and allows rapid response to emerging targets, with the ability to adjust the fences as new intelligence comes in. It also reflects that the system does have a planning process tied to the higher-level threat picture, rather than relying solely on external guidance or on tracking fixed, predetermined paths.
