Editing Directional Infrared Counter Measures (section)

===AN/AAQ-24===
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.<ref>{{Cite web|url=http://investor.northropgrumman.com/news-releases/news-release-details/northrop-grumman-completes-design-commercial-aircraft-protection|title=Northrop Grumman Completes Design of Commercial Aircraft Protection System|website=Northrop Grumman|language=en|access-date=2020-04-17}}</ref> The system will be installed by 2025<ref>{{Cite web|url=https://militaryleak.com/2019/01/05/northrop-grumman-receives-3-6-billion-contract-for-large-aircraft-infrared-countermeasure-systems/|title=Northrop Grumman receives $3.6 Billion contract for Large Aircraft Infrared Countermeasure systems|date=2019-01-05|website=MilitaryLeak|language=en-US|access-date=2020-04-17}}</ref> 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 [[United States Congress|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.<ref name=dcsa>{{Cite press release|url= https://www.dsca.mil/press-media/major-arms-sales/canada-anaaq-24v-directional-infrared-countermeasure-systems |title= Canada – AN/AAQ-24(V) Directional Infrared Countermeasure Systems |first1= Charles |last1= Taylor |first2= Paul |last2= Ebner |publisher=Defense Security Cooperation Agency |date= 15 September 2010 |access-date=2024-12-12 |archive-url=https://web.archive.org/web/20210328094741/https://www.dsca.mil/press-media/major-arms-sales/canada-anaaq-24v-directional-infrared-countermeasure-systems |archive-date=2021-03-28}}</ref> 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.<ref name=dcsa />

[[Large Aircraft Infrared Counter-Measure]] system (LAIRCM) was a [[US military|US Military]] requirement for protecting its large aircraft from infrared-guided missiles.<ref>{{Cite web|url=https://www.globalsecurity.org/military/systems/aircraft/systems/laircm.htm|title=Large Aircraft Infrared Countermeasures (LAIRCM)|publisher=GlobalSecurity.org|url-status=live|archive-url=https://web.archive.org/web/20011118050507/http://www.globalsecurity.org:80/military/systems/aircraft/systems/laircm.htm |archive-date=18 November 2001 |access-date=13 April 2020}}</ref> The AN/AAQ-24 Nemesis system was produced to serve this requirement.

LAIRCM-Lite is a C-17 program that uses a combination of laser jamming DIRCM and flares due to the limited availability of LAIRCM components.
