The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) ( 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; as an active seeker missile, NATO pilots thus use the brevity code "Fox Three" when firing the AIM-120.
