When an aircraft fires an AIM-120 missile, what is the voice call used?

The correct voice call for firing an AIM-120 missile is "FOX 3." This designation refers specifically to active radar-guided missiles, which encompasses the AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM). When the missile is launched, the pilot communicates this through the "FOX 3" call, indicating to other units that an air-to-air engagement is underway using this particular type of missile.

The other calls commonly used in air-to-air engagements are associated with different types of ordnance. "FOX 1" is used for semi-active radar-guided missiles, typically denoting weapons that require continued targeting through the launch platform's radar after release. "FOX 2" indicates the firing of an infrared-guided missile, commonly associated with heat-seeking capabilities. "FOX 4" is not a standard designation in the context of air-to-air missile usage. Therefore, understanding the different "FOX" calls is crucial for maintaining situational awareness and effective communication during air combat operations.
