AIM-120 AMRAAM

The early beam riding versions of the Sparrow missiles were integrated onto the McDonnell F3H Demon and Vought F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather McDonnell Douglas F-4 Phantom II fighter/interceptor, which lacked an internal gun in its U.S. Navy, U.S. Marine Corps, and early U.S. Air Force versions.

Designed for use against non-maneuvering targets such as bombers, the missiles initially performed poorly against fighters over North Vietnam, and were progressively improved until they proved highly effective in dogfights.

Together with the short-range, infrared-guided AIM-9 Sidewinder, they replaced the AIM-4 Falcon IR and radar guided series for use in air combat by the USAF as well.

The Phoenix was the first US fire-and-forget, multiple-launch, radar-guided missile: one which used its own active guidance system to guide itself without help from the launch aircraft when it closed on its target.

The Russian Air Force counterpart of AMRAAM is the somewhat similar R-77 (NATO codename AA-12 Adder), sometimes referred to in the West as the "AMRAAMski".

Likewise, France began its own air-to-air missile development with the MICA concept that used a common airframe for separate radar-guided and infrared-guided versions.

The AMRAAM was used operationally for the first time on December 27, 1992, when a USAF General Dynamics F-16D Fighting Falcon shot down an Iraqi MiG-25 that violated the southern no-fly-zone.

On 28 February 1994, a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly zone over Bosnia.

[13] In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets.

[14] On 18 June 2017, a US Boeing F/A-18E Super Hornet engaged and shot down a Sukhoi Su-22 of the Syrian Air Force over northern Syria,[15] using an AIM-120.

Neutral observers have confirmed the downing of an Indian Mig-21 whose pilot was captured by the Pakistani forces and later released as a goodwill gesture.

Typically, if the missile has sufficient energy during the terminal phase, which comes from being launched at close range to the target from an aircraft with an altitude and speed advantage, it will have a good chance of success.

It improves the aerial combat capabilities of US and allied aircraft to meet the threat of enemy air-to-air weapons as they existed in 1991.

It also incorporates a datalink to guide the missile to a point where its active radar turns on and makes terminal intercept of the target.

Using its built-in inertial navigation system (INS), the missile uses the information provided pre-launch to fly on an interception course toward the target.

The RAF initially opted not to use mid-course update for its Tornado F3 force, only to discover that without it, testing proved the AMRAAM was less effective in beyond visual range (BVR) engagements than the older semi-active radar homing BAE Skyflash (a development of the Sparrow), since the AIM-120's own radar is necessarily of lesser range and power as compared to that of the launch aircraft.

The C-variant has been steadily upgraded since it was introduced.The AIM-120C has smaller "clipped" aerosurfaces to enable increased internal carriage on the USAF F-22 Raptor from four to six AMRAAMs.

It helped the U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets – the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) is offset with a longer-range AMRAAM-D.

[37] 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.

[39] The AIM-120D (P3I Phase 4) 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 off-boresight) capability, and a max speed of Mach 4.

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.

In 2017, work on the AIM-260 Joint Advanced Tactical Missile (JATM) began to create a longer-ranged replacement for the AMRAAM to contend with foreign weapons like the Chinese PL-15.

Flight tests are planned to begin in 2021 and initial operational capability is slated for 2022, facilitating the end of AMRAAM production by 2026.

A more recent version is the High Mobility Launcher for the NASAMS, made in cooperation with Raytheon (Kongsberg Defence & Aerospace was already a subcontractor on the SLAMRAAM system), where the launch-vehicle is a Humvee (M1152A1 HMMWV), containing four AMRAAMs and two optional AIM-9X Sidewinder missiles.

[64][65] In February 2024, Raytheon flight-tested an upgraded version of AMRAAM-ER with an improved rocket motor and control actuator system and an AIM-120C-8 guidance head.

[75] Sales to Finland have stalled, because the manufacturer has not been able to fix a mysterious bug that causes the rocket motors of the missile to fail in cold tests.

[76] On May 5, 2015, the State Department has made a determination approving a possible Foreign Military Sale to Royal Malaysian Air Force for AIM-120C-7 AMRAAM missiles and associated equipment, parts and logistical support for an estimated cost of $21 million.

[77][78] In March 2016, the US government approved the sales of 36 units of AIM-120C-7 missiles to the Indonesian Air Force to equip their fleet of F-16 C/D Block 25.

[80][81][82] In March 2019, the US Department of State and Defense Security Cooperation Agency formally signed off on a US$240.5 million foreign military sale to support Australia's introduction of the NASAMS and LAND 19 Phase 7B program.

[91] In November 2023, the Swedish Defence Materiel Administration signed a contract worth US$605 million to purchase the AIM-120C-8, replacing the older AIM-120B, which will be sold back to the US for further donation to Ukraine.
