ASRAAM is a high speed, high agility, next generation, heat-seeking, air-to-air missile. Designed as a fire-and-forget missile, it is able to counter intermittent target obscuration in cloud as well as sophisticated infrared (IR) countermeasures. Although ASRAAM is predominantly for use in the within-visual-range (WVR) arena, it also has a capability in the beyond-visible-range (BVR) arena. The missile uses an imaging IR seeker (manufactured by Raytheon in the USA) and will equip Tornado F3 and Typhoon aircraft.
