C-17 LAIRCM mods restarted Published Oct. 26, 2012 By Robins Public Affairs ROBINS AIR FORCE BASE, Ga. -- Work on the C-17 LAIRCM, or Large Aircraft Infrared Countermeasures System, has been restarted at Robins. For the first time in two years, the modification line has come to life with a new crew of sheet metal and aircraft mechanics, electricians and hydraulics technicians from the 562nd Aircraft Maintenance Squadron, working to complete the first aircraft by the end of this month. Several sensors and lasers will be installed throughout the aircraft once modification has been completed. A second aircraft is currently being retrofitted with newer lasers. LAIRCM is a complex and highly effective missile threat detection system. It provides defense from widespread and growing missile threats by confusing guidance components in enemy air defense systems. It is designed to safeguard large transport and rotary-wing aircraft. The system is also used on the C-5 and C-130 aircraft.
