The Mitsubishi AAM-4 (Type 99 air-to-air missile) is a medium-range active radar homing air-to-air missile, considered as modern beyond-visual-range missile developed in Japan and intended to replace the semi-active radar homing AIM-7 Sparrow missile in service. It has been operational since 1999.
The main contractor is Mitsubishi Electric. The 2010 AAM-4B was the world's first air-to-air missile with an AESA radar seeker.
