Which of the following is NOT a ground-based radar used for ballistic missile warning?

• A. Upgraded Early Warning Radar System
• B. PAVE Phased Array Warning System
• C. Perimeter Acquisition Radar Attack Characterization System
• D. Global Hawk Detection System

Answer: (D)

The Global Hawk Detection System is not classified as a ground-based radar used for ballistic missile warning. Instead, it is an unmanned aerial vehicle (UAV) that operates primarily for intelligence, surveillance, and reconnaissance (ISR) missions. While it can collect data and monitor areas for various military applications, it does not function as ground-based radar does for detecting and tracking ballistic missiles. In contrast, the other systems listed—such as the Upgraded Early Warning Radar System, PAVE Phased Array Warning System, and the Perimeter Acquisition Radar Attack Characterization System—are all examples of ground-based radar technologies explicitly designed for the detection and tracking of ballistic missiles. These systems play a crucial role in missile warning architectures, providing early warnings to detect incoming threats and allowing for defensive measures to be implemented. Their core purpose is to enhance national security by providing timely data on potential airborne attacks.
