Direct proof of use
The AH-1W Super Cobra is directly documented in the 1990 Gulf War through official Marine Corps and naval aviation sources. Marine Corps University describes Marine Bell AH-1 SuperCobra attack helicopters from HMLA-369 launching on January 17, 1991, in response to air-support calls from Marines and Navy SEAL personnel along the Saudi-Kuwait border north of al-Khafji.
A Marine Corps History Division account gives AH-1W-specific detail for the following day: four AH-1Ws from HMLA-369, operating from Mishab, reported destroying two 120 mm mortar tubes, ammunition trucks, and two buildings with TOW missiles, rockets, and 20 mm gunfire after reconnaissance teams near Khafji came under artillery fire.

Timeline
The first sourced AH-1W-related Gulf War milestone in this record is January 17, 1991, the first day of Operation Desert Storm. HMLA-369 AH-1s launched at 0400 to investigate reports of Iraqi tanks north of al-Khafji and instead attacked Iraqi observation posts with TOW and Hellfire missiles.
On January 18, four HMLA-369 AH-1Ws flew from Mishab and struck mortar tubes, ammunition trucks, and buildings with TOW missiles, rockets, and 20 mm guns. The Marine Corps History Division account says the Cobras stood alert at Mishab and used Safaniya to rearm while responding to artillery threatening Marine reconnaissance and surveillance teams around Khafji.

Operational role
The sourced record places the AH-1W on the U.S.-led coalition side of the war, operated by U.S. Marine Corps light-attack helicopter units rather than transferred to another Gulf War participant. The documented operator in the detailed January missions is HMLA-369, using Super Cobras for alert close air support, anti-armor search, and attacks on Iraqi artillery-support and observation targets near al-Khafji.
The National Naval Aviation Museum gives the broader campaign result for Marine AH-1W squadrons, crediting them in Operation Desert Storm with destroying Iraqi tanks and armored vehicles. In the detailed Khafji-area record, the aircraft's documented weapons included Hellfire, TOW, 2.75-inch rockets, and the 20 mm cannon.
