The AN/AAQ-24 system is a directional infrared countermeasure (DIRCM) system. It consists of a missile warning system , an integration unit, a processor, and laser turrets (Small Laser Transmitter Assembly, SLTA). Early versions of this system used an arc lamp to generate the jammer signal.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing ("heat seeking") missiles by confusing the missiles' infrared guidance system so that they miss their target (electronic countermeasure). Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm.
Northrop Grumman's (NOC) business unit, Northrop Grumman Systems Corp., wins a $31.2-million deal for the delivery of the large aircraft infrared countermeasures infrared missile warning sensor.

When the aircraft's sensors detect a threat, the countermeasure dispenser system automatically launches radiofrequency and infrared countermeasures at the optimum time to defeat incoming missiles. The ALE is compatible with a wide variety of countermeasures such as different types of flares and chaff. It is also designed to work with advanced ...
An ALQ-144 jammer mounted on an OV-10 Bronco.. The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infrared guided missile countermeasure devices ().They were developed by Sanders Associates in the 1970s to counter the threat of infrared guided surface-to-air missiles like the 9K32 Strela-2.
