Directional Infrared Counter Measures

Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional.

DIRCM systems instead aim their IR output directly at the missile using some source of tracking information and a trainable emitter.

The pulsing flashes of IR energy confuse the missile guidance system, preventing the tracking of the target aircraft.

These systems are intended for potential fitting to commercial carriers pending the completion of multiple tests on the viability of such options.

In 2010, the US Defense Security Cooperation Agency announced to Congress a possible sale to Canada of eight AN/AAQ-24(V) DIRCMs including equipment and services for a total value of up to US$72 million.
