Northrop Grumman will integrate the latest version of the DoN LAIRCM system onto U.S. aircraft. The DoN LAIRCM is currently in service on both rotary and fixed wing aircraft. Additionally, Northrop Grumman will install DoN LAIRCM systems on aircraft owned by allied governments.

“The DoN LAIRCM award signifies Naval Air System Command’s continued confidence in Northrop Grumman’s 50 years of expertise in missile warning and infrared countermeasures systems,” said Bob Gough, vice president, navigation, targeting and survivability, Northrop Grumman. “We remain fully committed to delivering this life-saving capability to our warfighters.”

Under this latest task order, Northrop Grumman will continue to provide support and maintenance for the battle-proven DoN LAIRCM systems that are currently installed on U.S. military aircraft. One of the most advanced aircraft survivability equipment available, Northrop Grumman's LAIRCM system provides maximum aircraft and aircrew survivability. The DoN LAIRCM system defends aircraft against surface-to-air infrared missile threats. The system automatically counters advanced infrared missile systems by detecting, tracking and jamming the threat with a high-intensity laser beam.

Northrop Grumman’s Infrared Countermeasures (IRCM) systems are installed on more than 1,500 aircraft of more than 80 different platform types worldwide and are the frontline defense system for U.S. Air Force, Army, Navy and Marine Corps platforms.

The AN/AAQ-24(V)25, DoN LAIRCM system combines advanced, two-color Infrared Missile Warning System (MWS) and Directed Laser Countermeasures to defeat shoulder-launched missiles fired at aircraft. The system will be deployed on a total of 156 United States Marine Corps (USMC) CH-53E, CH-53D and CH-46E medium-lift and heavy-lift, assault support helicopters to meet the USMC urgent needs for a “…state-of-the-art, reliable, carrier-based and land-based Missile Warning System (MWS) and Infrared Countermeasure (IRCM).”

The DoN LAIRCM system consists of five major components: Five Infrared (IR) MWS sensors; a dedicated Central Processor; a Control Indicator Unit (CIU) for cockpit display; two Pointer-Tracker/Jamming Subsystems or Guardian Laser Tracker Assemblies (GLTA) consisting of four-axis stabilized gimbaled system, a Fine Track Sensor (FTS) and a ViperTM laser.
