The Advanced Short Range Air-to-Air Missile, also known by its United States identifier AIM-132, is an imaging infrared homing ("heat seeking") air-to-air missile, produced by MBDA. It is currently in service in the Royal Air Force (RAF) and Royal Australian Air Force (RAAF), replacing the AIM-9 Sidewinder. The project started as a British-German collaboration in the 1980s; eventually the Germans left the project due to concerns over the missile’s performance. The British proceeded on their own, and the missile was introduced into RAF service in 1998. The ASRAAM was developed to have longer range and higher speed than the Sidewinder, whilst exceptional 50g manoeuvrability is provided by a sophisticated control system using innovative body lift technology coupled with tail control.
