Direct proof of use
The MiG-23 is directly documented in the 1990 Gulf War as an Iraqi Air Force aircraft type encountered and destroyed during Operation Desert Storm. An Air Force Historical Research Agency paper by Daniel L. Haulman states that USAF pilots shot down 37 Iraqi aircraft during the Gulf War period and identifies eight MiG-23s among the Iraqi airplanes lost in those air-to-air victories.
Air & Space Forces Magazine's published Desert Storm data gives a second loss-accounting view. Its Iraqi fixed-wing aircraft loss table lists MiG-23 losses as nine in air-to-air combat and eight on the ground, for 17 MiG-23s in that table; the same note says the totals exclude aircraft flown to Iran.

Combat chronology
The documented combat-use window for this record is the January-February 1991 Operation Desert Storm campaign. Haulman's AFHRA paper describes Iraqi aircraft being shot down in 1991, then traces how coalition attacks shifted from runways to aircraft shelters and aircraft parked in the open as Iraqi pilots avoided further air combat.
By late January, coalition air superiority had effectively removed the Iraqi Air Force as an operational threat. Haulman writes that General Norman Schwarzkopf declared complete air supremacy in the theater on January 27, 1991, after coalition air combat victories and airfield attacks eliminated the Iraqi Air Force threat early in Desert Storm.

Operational role
In the Gulf War record, the MiG-23 appears on the Iraqi side as a fighter and fighter-bomber family rather than as a coalition strike aircraft. The source-backed claims here support fielding, air-combat losses, and ground losses; they do not support a specific MiG-23 bombing sortie or a confirmed MiG-23 weapon release in the campaign.
The available official narrative places the MiG-23 inside the broader collapse of Iraqi air resistance. Haulman states that Iraqi aircraft were destroyed in the air, in hardened shelters, and in the open, and that Iraq then flew 121 aircraft to Iran by the end of Desert Storm. Air & Space Forces Magazine's MiG-23 loss table separately distinguishes the 17 listed MiG-23 losses from aircraft flown to Iran, keeping destruction and evacuation as separate categories.
