Which region provides an ongoing capability to detect, validate, and warn of any aircraft and/or cruise missile threat in its area of operations that could threaten North American security?

• A. Eastern Air Defense Sector
• B. Alaskan region
• C. Canadian region
• D. Continental United States region

Answer: (B)

The Alaskan region is the forward-facing node for detecting and warning about threats coming toward North America from the Arctic and North Pacific. Its position allows continuous, real-time detection and validation of aircraft or cruise missile activity that could threaten North American security, and it can rapidly issue warnings and coordinate defenses. Other regions cover their respective areas (east, continental U.S., and Canadian airspace), but Alaska uniquely provides ongoing capability for early threat detection from directions that could reach North America first.
