What is the primary function of a CMWS in aviation?

The primary function of a Countermeasure Warning System (CMWS) in aviation is to detect threats from missiles. This system plays a critical role in enhancing the safety and survivability of aircraft by identifying incoming missile threats, often through the use of sensors that can detect the heat or electronic signatures produced by missile launches. By accurately identifying these threats, the CMWS provides essential alerts to pilots, enabling them to take evasive actions or deploy countermeasures effectively to protect the aircraft and its occupants.

While guiding aircraft, dispensing chaff, and tracking weather conditions are important aspects of aviation, they do not define the specific role of a CMWS, which is exclusively focused on threat detection and response.
