Airborne Early Warning (AEW) refers to a military surveillance system that uses aircraft equipped with radar and other sensors to detect and track potential threats from the air and sea. These aircraft can monitor large areas and provide real-time information to command centers, enhancing situational awareness and enabling timely responses to emerging threats. AEW systems are crucial for national defense, as they help identify enemy aircraft, missiles, and naval vessels before they can pose a danger. By maintaining a constant watch over vast regions, AEW platforms like the E-3 Sentry or E-2 Hawkeye play a vital role in modern military operations.
