Direct proof of use
The F/A-18 Hornet is directly documented in the 1990 Gulf War through U.S. Navy and Canadian government sources. NAVAIR states that more than 210 U.S. Navy, Marine Corps, and Canadian F/A-18 Hornets were engaged in Operation Desert Storm, hit more than 6,000 targets, delivered 18 million pounds of ordnance, and flew more than 30,000 flight hours.
The official NAVAIR Hornet product page also describes the aircraft's Gulf War combat role, saying the F/A-18 shot down enemy fighters and bombed enemy targets on the same mission during Operation Desert Storm. The National Naval Aviation Museum identifies an F/A-18C in its collection as one of two Hornets that shot down Iraqi MiG-21 Fishbed fighters on January 17, 1991, the first day of Operation Desert Storm.

Combat chronology
Canadian CF-18s entered the theater before the air war. Canada's Operation SCIMITAR history says the first six CF-18s left Baden, Germany on October 7, 1990 and arrived in Doha, Qatar on October 8, with additional aircraft arriving on October 11 and 12. The same account says the aircraft were sent to provide combat air patrols for Canadian ships and interception capability if Iraqi aircraft flew outside Iraqi airspace.
When Operation Desert Storm began on January 17, 1991, Hornets were part of the coalition air campaign. NAVAIR's program history gives the broader scale of F/A-18 use across U.S. Navy, Marine Corps, and Canadian aircraft, while the museum record gives a dated air-to-air example from the first day: two F/A-18C Hornets shot down Iraqi MiG-21s.
Canada's Operation FRICTION history gives additional CF-18 milestones. It says Canadian CF-18s were flying combat air patrol in Whiskey-1 when the air war began, shifted into sweep-and-escort missions from January 20, attacked an Iraqi fast patrol boat with 20 mm guns on January 30, and made their first bombing run on February 24 with Mk 82 500-pound bombs. Hostilities ended on February 28, after which the Canadian account records 56 CF-18 bombing missions.

Operational role
The documented Hornet role in the 1990 Gulf War was multirole rather than a single mission category. NAVAIR lists fleet air defense, reconnaissance, and suppression of enemy ground forces among the missions flown by Hornets in Operation Desert Storm. Its product page frames the same theater as an early demonstration of the F/A-18's fighter-attack design: air-to-air engagements and bombing on the same mission.
Canadian sources show the CF-18 part of that multirole pattern from a coalition partner perspective. The Canadian government says Canada sent 24 CF-18s to Qatar for the American-led Desert Shield and Desert Storm campaigns. Its operation histories document combat air patrol, sweep and escort, a gun attack on an Iraqi fast patrol boat, and late-war bombing missions against Iraqi ground targets.
