The AIM-120[a] Advanced Medium-Range Air-to-Air Missile (AMRAAM) (/æmræm/ AM-ram) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the brevity code "Fox Three".
