Direct proof of use
A CSIS-published chapter drawing on the Gulf War Air Power Survey records AIM-9 and AIM-9M Sidewinder kills in Desert Storm air-to-air combat. Its Iraqi air-loss table lists Sidewinder engagements by U.S. Navy F/A-18s, U.S. Air Force F-15Cs, Royal Saudi Air Force F-15Cs, and a U.S. Navy F-14 against Iraqi fixed-wing aircraft and a helicopter between January 17 and February 7, 1991.
A 1991 U.S. Air Force white paper separately states that AIM-9 missiles destroyed six enemy fixed-wing aircraft in Desert Storm. That count supports the missile's fixed-wing air-to-air role, while the CSIS table gives the dated engagement detail and also records a February 7 F-14 AIM-9M helicopter kill.

Operational setting
The Sidewinder appeared in a campaign where coalition aircraft rapidly established air superiority and Iraqi aircraft offered comparatively few air-to-air engagements. A GAO review of Operation Desert Storm notes that nearly all Iraqi aircraft shot down in the air were attacked by F-15Cs, and that more than 100 Iraqi combat aircraft flew to Iran during the war.
Within that setting, the AIM-9 was the short-range infrared missile complement to radar-guided weapons such as the AIM-7 Sparrow. The U.S. Air Force fact sheet describes the Sidewinder as a supersonic heat-seeking air-to-air missile carried by fighter aircraft, with an infrared seeker and high-explosive warhead.

Documented engagements
The dated Sidewinder events in the Gulf War Air Power Survey-derived table show coalition use across several fighter communities. On January 17, 1991, a U.S. Navy F/A-18 was credited with an AIM-9 kill against an Iraqi MiG-21. On January 24, Royal Saudi Air Force F-15Cs were credited with AIM-9 kills against Mirage F1 aircraft.
U.S. Air Force F-15Cs used AIM-9s in later January and early February engagements, including MiG-23 kills on January 27 and MiG-21 and Su-25 kills on February 6. The same table records a U.S. Navy F-14 AIM-9M kill against an Iraqi Mi-8 helicopter on February 7.

Role in the conflict
The AIM-9's conflict role was air defense and air superiority support rather than ground attack. Coalition fighters carried and fired the missile when Iraqi aircraft entered short-range engagement conditions, while other coalition aircraft and weapons attacked Iraq's air-defense network, airfields, ground forces, and strategic targets.
The available direct sources support documented missile firings and credited kills, but they do not identify every Sidewinder carried in theater or every attempted shot by aircraft, unit, and pilot. The record is strongest for the dated credited engagements and the fixed-wing kill total reported in U.S. Air Force and Gulf War Air Power Survey-derived material.
