Since the beginning of the 1960s, Diehl BGT Defence, as European prime contractor and system house, has manufactured more than 35,000 Sidewinder missiles of the AIM-9B, AIM-9B/FGW Mod. 2 and AIM-9L types for nearly all NATO countries and pushed ahead with their further development up to the most recent AIM-9L/I-1 version. The latter provides improved resistance to common infrared countermeasures. Sidewinder is an air-to-air missile developed by the US Navy and produced by Diehl BGT Defence under license for use within the pilot's visual range. It is integrated in almost all European and US fighter aircraft and is now in use in more than 30 countries.
Diehl Raytheon Missile Systeme GmbH, Überlingen, founded in 2004 by Diehl VA Systeme and Raytheon, is responsible for modernization and marketing of the existing AIM-9L/M Sidewinders. Its tasks also include worldwide logistics and life-cycle maintenance of Sidewinder AIM-9L/M missiles as well as AMRAAM marketing support for Raytheon in Europe.
