Which system is responsible for cueing ATIRCM to missile threats?

The correct answer is the CMWS, which stands for Common Missile Warning System. This system is designed to detect and identify incoming missile threats through the use of infrared sensors. Once a missile threat is detected, the CMWS sends cueing information to the ATIRCM (Advanced Threat Infrared Countermeasure) system, which then activates countermeasures to mitigate the threat.

By providing rapid and accurate detection of missile threats, the CMWS plays a crucial role in the overall defense strategy of an aircraft. This cueing process is essential for the ATIRCM's effectiveness, as it enables timely responses to protect the aircraft from potential harm.

The other systems do not have this specific responsibility in relation to missile threat cueing. While the IR tracker may be involved in detecting infrared signatures, it does not integrate directly with missile warning systems for the purpose of triggering countermeasures. The JHCU (Joint Helmet-Mounted Cueing System) is mainly focused on targeting and situation awareness for pilots rather than missile threat detection. Launch Control is a term typically associated with initiating weapons systems rather than monitoring or cueing missile threats.
