Which component would typically provide a warning when a missile is approaching?

A Missile Approach Warning System (MAWS) is specifically designed to detect and provide warnings of incoming missile threats. It utilizes sensors that can detect the infrared signatures or radar emissions of missiles, allowing it to identify and alert operators about the missile's approach. This system plays a crucial role in enhancing the survivability of vehicles or aircraft, as it provides timely alerts that allow for evasive measures or deployment of countermeasures.

In contrast, a RADAR Warning Receiver (RWR) is tailored for identifying radar emissions from enemy systems, which may help in situational awareness but does not directly indicate the presence of an incoming missile. A Countermeasure Dispensing System (CMDS) is focused on releasing countermeasures, such as flares or chaff, when a threat is identified but does not provide warning itself. Lastly, a Laser Warning Receiver (LWR) detects laser illumination from targeting systems but is specific to laser threats rather than missile approaches. Each of these other systems serves an important role within electronic warfare, but the MAWS is the dedicated system for missile approach alerts.
