Direct proof of use
Royal Saudi Air Force F-5E Tiger II aircraft were used on the coalition side of the 1990 Gulf War. A U.S. Air Force image record identifies a Royal Saudi Air Force F-5E flying with two U.S. Air Force F-15C Eagles during a mission in support of Operation Desert Storm, with all three aircraft armed with AIM-9 Sidewinder air-to-air missiles.
The F-5's combat exposure is also documented in a fixed-wing attrition table for Desert Storm. The table lists a Royal Saudi Air Force F-5E as a combat loss at 0630Z on February 13, 1991 near Wadi al-Kirk, caused by anti-aircraft artillery.

Timeline
Operation Desert Storm opened on January 17, 1991, after the Desert Shield buildup. The F-5E evidence in this record places Saudi aircraft in the air campaign rather than in a transfer or captured-equipment context.
On February 13, 1991, a Royal Saudi Air Force F-5E was lost near Wadi al-Kirk to anti-aircraft artillery. The loss is the clearest dated F-5 incident tied to the campaign.

Narrative
Saudi F-5Es served as part of the broader coalition air effort against Iraqi forces in and around Kuwait. Open reference material describes their Gulf War role as close air support and aerial interdiction against Iraqi units in Kuwait, while the official U.S. Air Force image record provides a direct visual record of a Saudi F-5E flying an Operation Desert Storm support mission.
The aircraft's Gulf War record should be separated from Saudi possession of the type before the war. Saudi Arabia had acquired F-5E/F and RF-5E aircraft before 1990, but the conflict-use claim here rests on wartime mission documentation and the February 1991 combat-loss record.
The published evidence identifies the operator as the Royal Saudi Air Force and the catalog side as coalition forces. It does not show Iraqi use, transfer during the war, or a specific F-5 strike result.
