They do? That's news to the Air Force. They're practically begging for a new improved missile to replace it.
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.
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, improved HOBS (High-Angle Off-Boresight) capability, and a 50% increase in range. The 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.
AMRAAM uses two-stage guidance when fired at long range. The aircraft passes data to the missile just before launch, giving it information about the
location of the target aircraft from the launch point and its direction and speed. The missile uses this information to fly on an interception course
to the target using its built in inertial navigation system (INS). This information is generally obtained using the launching aircraft's radar,
although it could come from an Infra-red search and track system, from a data link from another fighter aircraft, or from an AWACS aircraft.
(see it DOES have a IR option)
After launch, if the firing aircraft or surrogate continues to track the target, periodic updates—such as changes in the target's direction and
speed—are sent from the launch aircraft to the missile, allowing the missile to adjust its course, via actuation of the rear fins, so that it is
able to close to a self-homing distance where it will be close enough to "catch" the target aircraft in the basket (the missile's radar field of view
in which it will be able to lock onto the target aircraft, unassisted by the launch aircraft).
Once the missile closes to self-homing distance, it turns on its active radar seeker and searches for the target aircraft. If the target is in or near
the expected location, the missile will find it and guide itself to the target from this point. If the missile is fired at short range, WVR or the
near BVR, it can use its active seeker just after launch
Boresight mode (aim 120 d)
Apart from the slave mode, there is a free guidance mode, called boresight. This mode is radar guidance-free, the missile just fires and locks the
first thing it sees. This mode can be used for defensive shot, i.e. when the enemy has numerical superiority. SO radar jamming WONT WORK on that
Is that good zap? i think thats all the info on the 120's newest model.
ZAPHOD,and COB. the newest HARM has the seek on jamming and passive radar. Although the AIM 120 does have a similiar ability with the BORESIGHT
OOh look at this. the HARM is going to be used as a air to surface killer too.
The Navy's FY 2016 budget included funding for an extended range AARGM-ER that utilizes the existing guidance system and warhead of the AGM-88E with a
solid integrated rocket-ramjet for double the range. Development funding will last to 2020.
In September 2015, the AGM-88E successfully hit a mobile ship target in a live-fire test, demonstrating the missile's ability to use anti-radiation
homing and millimeter wave radar to detect, identify, locate, and engage moving targets.
