Which system protects aircraft from heat seeking missiles?

The Infrared Counter Measure Set (IRCM) is specifically designed to protect aircraft from heat-seeking missiles, which typically track the infrared signature of the aircraft's engines. The IRCM works by using various technologies, such as flares or laser systems, to confuse or distract incoming infrared missile guidance systems. By emitting counteracting infrared signatures or disrupting the missile's guidance, the IRCM increases the chances of the aircraft avoiding a hit.

This protection mechanism is crucial in combat or hostile environments where heat-seeking missiles are likely to be employed. The other systems mentioned, while integral to aircraft defense, serve different purposes. The Missile Warning System (MWS) identifies incoming threats, the Radar Warning Receiver (RWR) detects radar emissions, and the Electronic Countermeasure System (ECM) focuses on jamming or deceiving enemy radar and communications. While these systems contribute to overall aircraft survivability, it is the IRCM that specifically addresses the threat of heat-seeking missiles effectively.
