AIM-120 AMRAAM — Air-to-Air
Open in interactive gallery →

The AIM-120 AMRAAM is the standard beyond-visual-range air-to-air weapon of the United States and its allies, and the Western world's most-produced active-radar-homing air-to-air missile. Developed by Hughes (now Raytheon, today part of RTX) and entering service in 1991, the AMRAAM replaced the semi-active AIM-7 Sparrow across every Western air force of consequence. It arms the F-22, F-35, F-15, F-16, F/A-18, Eurofighter Typhoon, Dassault Rafale (alongside the European MICA and Meteor), Saab Gripen, Tornado, Harrier, and most other modern Western fighters.

What sets the AMRAAM apart is active radar homing in the terminal phase. The older AIM-7 Sparrow required the launching aircraft to keep its radar locked on the target throughout the missile's flight, which constrained the shooter's manoeuvring. The AMRAAM's onboard radar takes over in the final seconds, letting the launching aircraft turn away after firing — "launch-and-leave" — to engage other targets or evade defensive fire. Two-way datalink mid-course updates from the launching aircraft make the missile dramatically more survivable in multi-target engagements.

Several variants have evolved the design. The original AIM-120A/B had a 35-mile range and was the in-service variant during the 1991 Gulf War, where it scored its first combat kill. The AIM-120C-5 introduced clipped fins for internal carriage on the F-22, longer reach, and improved electronic counter-counter-measures. The current AIM-120D (D-3 variant) extends range to roughly 100 miles, adds GPS-aided mid-course guidance, and improves kinematics. Its successor, the AIM-260 JATM, entered low-rate production in 2023 with extended range to compete with the Chinese PL-15 and Russian R-37M.

By 2026, more than 30,000 AMRAAMs have been built and exported to over 40 countries. The missile has scored at least 16 air-to-air kills in combat — primarily during the 1991 Gulf War, the 1990s Yugoslav and Bosnian wars, the 2022+ Ukrainian air war (where it equips Ukrainian F-16s, MiG-29s, and ground-launched NASAMS surface-to-air systems), and the 2025 strikes on Iranian nuclear infrastructure.

For Kids — a shorter, friendlier version

The AIM-120 AMRAAM (everyone calls it "am-RAM") is America's main air-to-air missile. Unlike the heat-seeking Sidewinder, the AMRAAM uses its own tiny radar to find enemy planes. It can hit targets over 100 miles away — far beyond what a pilot can see with their eyes.

The name stands for "Advanced Medium-Range Air-to-Air Missile." The AMRAAM is about 12 feet long — half as long as a small car. It weighs 335 pounds, can fly at Mach 4 (about 3,000 mph), and has a 50-pound explosive charge.

The AMRAAM is a "fire and forget" missile. The pilot points the radar at an enemy plane, the missile launches, and from then on the missile's own radar finds the target — even if the pilot turns and flies away. This lets one fighter shoot down multiple enemies at the same time, all by itself.

The AMRAAM is used by 41 countries, including all NATO members, plus Israel, Japan, Australia, South Korea, and many more. The U.S. has built over 14,000 AMRAAMs since 1991.

The newest version is the AIM-120D-3 (since 2022) with an even longer reach. AMRAAMs have defeated more than 14 enemy aircraft in real combat — including the first "beyond-visual-range" air-to-air kills in history, during the 1992 No-Fly Zone enforcement over Iraq.

Fun Facts

  • AMRAAM stands for "Advanced Medium-Range Air-to-Air Missile."
  • The AMRAAM has its own tiny radar in its nose — it doesn't need the launching plane to guide it.
  • AMRAAMs can hit enemy planes over 100 miles away — much farther than a pilot can see.
  • The U.S. has built over 14,000 AMRAAMs since 1991.
  • 41 countries use AMRAAMs — including all NATO members, plus Israel, Japan, Australia, and South Korea.
  • AMRAAMs can fly at Mach 4 — about 3,000 mph.
  • The first "beyond-visual-range" air-to-air kill in history was made with an AMRAAM in 1992.

Kids’ Questions

How is radar guidance different from heat-seeking?

Heat-seeking missiles like the Sidewinder use an infrared sensor to find enemy engine exhaust — they're great at close range but can be fooled by flares. Radar-guided missiles like the AMRAAM send out their own radio waves and listen for echoes from the enemy plane. Radar works in all weather, day or night, and at much longer range than infrared. The AMRAAM doesn't need to see heat — just a radar reflection. The trade-off: enemy planes can detect the radar signal and know they're being attacked. Heat-seekers are silent and harder to detect. Good fighter pilots carry both kinds of missiles.

What is 'fire and forget'?

Old air-to-air missiles needed the launching airplane to keep its radar pointed at the enemy plane until the missile arrived — sometimes 30 seconds or more. If the pilot turned away, the missile lost track. The AMRAAM changed this. After launch, the AMRAAM's own radar in the missile finds the target. The pilot can immediately turn away or attack a different target — "fire and forget." This is much safer for the pilot, who doesn't have to fly straight toward the enemy while waiting for the missile to arrive. Plus, a fighter can fire multiple AMRAAMs at different targets at the same time.

Frequently Asked Questions

What is an AIM-120 AMRAAM?

The AIM-120 AMRAAM is the U.S. and allies' beyond-visual-range air-to-air missile. It flies on inertial guidance with mid-course datalink updates from the launching aircraft, then switches to active radar homing in the terminal phase — allowing the launching aircraft to turn away ("launch-and-leave") after firing.

How far can an AIM-120 fly?

Range depends on the variant. The original AIM-120A had a roughly 35-mile range; the current AIM-120D-3 reaches around 100 miles. The successor AIM-260 JATM goes further, though exact figures remain classified.

AIM-120 vs Meteor: which is better?

The European MBDA Meteor ramjet missile has a much larger no-escape zone — the area within which a target can't outmanoeuvre the missile — than even the AIM-120D, thanks to sustained thrust through the entire engagement. The AIM-120D has a comparable maximum range, but its kinetic energy degrades faster after launch. The American AIM-260 JATM is being developed in part to close the gap with Meteor and the Chinese PL-15.

How much does an AIM-120 cost?

Unit cost (FY 2024 dollars) sits around $1.1–1.2 million per AIM-120D-3 missile, mid-tier pricing among modern beyond-visual-range missiles. The successor AIM-260 is expected to cost more.

Has the AIM-120 been used in combat?

Yes — the AMRAAM has scored at least 16 confirmed air-to-air kills since its 1992 first kill, an Iraqi MiG-25 over Iraq's no-fly zone. Combat use spans the 1991 Gulf War, the 1990s Bosnian air war, the 2022+ Russia–Ukraine war (where Ukrainian F-16s and NASAMS-AMRAAM ground systems have used it extensively), and the 2025 strikes on Iranian nuclear infrastructure.

What aircraft carry the AIM-120?

The AIM-120 arms nearly every Western fighter built after 1990: F-22, F-35, F-15, F-15EX, F-16, F/A-18 Super Hornet, Eurofighter Typhoon, Dassault Rafale (alongside MICA and Meteor), Saab Gripen, Panavia Tornado, AV-8B Harrier, Mitsubishi F-2 (Japan), and KAI FA-50 (South Korea).
