AN/AAQ-24 Nemesis The AN/AAQ-24 system is a directional infrared countermeasure (DIRCM) system. It consists of a missile warning system (
AN/AAR-54), 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. The newer versions of this system manufactured by
Northrop Grumman use diode-based
laser pumping systems known by the name GUARDIAN. These systems are intended for potential fitting to commercial carriers pending the completion of multiple tests on the viability of such options. The AN/AAQ-24 system is installed in the
Northrop Grumman Guardian system marketed for commercial aircraft. The system will be installed by 2025 on
C-17 Globemaster III,
MC-130,
CV-22 Osprey, and the
CH-53E Super Stallion. 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. Other material and services would include publications and technical documentation, personnel training and training equipment, U.S. Government (USG) and contractor engineering, technical and logistics support services. The 101KS-O is the first DIRCM that is deployed on any fighter aircraft. ==See also==
