What is the main purpose of the Infrared Counter Measure Set (IRCM)?

The Infrared Counter Measure Set (IRCM) is specifically designed to protect aircraft from threats posed by heat-seeking missiles, which are guided by infrared signals emitted by the aircraft's engines or other heat sources. The primary function of the IRCM is to detect, track, and counteract these missile threats by using various techniques to obscure or deceive the missile's guidance system, thus enhancing the survivability of the aircraft in hostile environments. This involves the use of infrared flares or laser systems that create misleading thermal signatures, making it difficult for the missiles to lock on to the actual aircraft heat signature.

In contrast, enhancing fuel efficiency, improving navigation accuracy, and facilitating communication with ground control are unrelated functions that do not align with the primary mission of the IRCM. Each of these aspects plays a significant role in aviation but is not connected to the protection mechanisms against missile threats.
