The
AIM-120D is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (
Pk). Raytheon began testing the D model on August 5, 2008, the company reported that an AIM-120D launched from an
F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the
White Sands Missile Range.
[19] The range of the AIM-120D is classified, but is thought to extend to about 100 miles (160 km).

The AIM-120D (P3I Phase 4, formerly known as AIM-120C-8) is a development of the AIM-120C with a two-way data link, more accurate navigation using a GPS-enhanced IMU, an expanded no-escape envelope, and improved HOBS (high off-boresight) capability. The AIM-120D max speed is Mach 4
[7] and AIM-120D is a joint USAF/USN project, and is currently in the testing phase. The USN was scheduled to field it from 2014, and AIM-120D will be carried by all Pacific carrier groups by 2020, although the
2013 sequestration cuts could push back this later date to 2022.
[20] The
Royal Australian Air Force requested 450 AIM-120D missiles, which would make it the first foreign operator of the missile. The procurement, approved by the US Government in April 2016, will cost $1.1 billion and will be integrated for use on the F/A-18F Super Hornet, EA-18G Growler and the F-35 Lightning II aircraft.
