Airborne Warning and Control System (AWACS) aircraft are critical for defending against low-altitude attacks because they provide long-range surveillance that overcomes the limitations of ground-based radar, which can be hindered by terrain or the Earth's curvature.12

By operating at high altitudes, AWACS aircraft utilize powerful radar systems to detect and track low-flying targets at distances of up to 370 km (200 nautical miles). Historically, the effectiveness of these systems was limited by interference from land clutter—reflections from the ground that mask small, low-flying targets. However, modern AWACS platforms incorporate advanced clutter-rejection circuitry and signal processing, such as Doppler frequency shift analysis, to distinguish moving aircraft from stationary ground objects.123

Beyond detection, these aircraft function as mobile command and control centers. Onboard computers assess enemy activity, while secure, high-speed communication systems allow operators to direct friendly interceptors or surface-to-air missile units to counter the threat. This combination of wide-area surveillance, sophisticated data processing, and real-time tactical control makes them essential for maintaining air superiority against low-altitude penetrations.12
