Coalition Air Monitoring & Responses in the Gulf War (1990–1991) Background When Iraq invaded Kuwait in August 1990, the U.S.-led coalition rapidly deployed to Saudi Arabia and surrounding areas under Operation Desert Shield, later transitioning to Operation Desert Storm in January 1991. Control of the skies was considered critical for defending coalition forces and preventing further Iraqi expansion into neighboring states. Surveillance & Monitoring AWACS (Airborne Warning and Control System): The U.S. Air Force’s E-3 Sentry AWACS aircraft played a central role. Flying racetrack patterns, they provided wide-area radar coverage, detecting and tracking Iraqi aircraft hundreds of miles away. AWACS crews relayed real-time information to command centers and to fighters on patrol. Ground-Based Radar: Saudi and coalition radar sites created overlapping coverage across the Gulf region. This helped to build a layered air picture alongside AWACS feeds. Reconnaissance Assets: U-2 aircraft and satellites added intelligence on Iraqi airfields, aircraft dispersal, and potential launch activity. Identification & Rules of Engagement Coalition forces were required to positively identify aircraft before taking action. This was partly to avoid tragic misidentification with neutral or civilian flights. Iraqi aircraft flying near or across borders were treated with suspicion, especially those approaching Saudi Arabia, Turkey, or Iran.
