Direct proof of use
The AH-64 Apache attack helicopter is directly documented in the 1990 Gulf War through Task Force Normandy, the joint U.S. Army and U.S. Air Force mission that opened Operation Desert Storm. Army University Press describes eight Army AH-64 Apache helicopters working with four Air Force MH-53J Pave Low helicopters to destroy two Iraqi early-warning radar sites on January 17, 1991, opening an air corridor for the wider coalition air campaign.
The official Army University Press staff ride page identifies the aircraft more specifically as eight Army AH-64A Apache helicopter teams from the 1st Battalion, 101st Aviation Brigade, 101st Airborne Division. It states that the task force conducted a deep attack into Iraq to destroy two early-warning radar sites before the start of the Desert Storm air campaign.

Combat chronology
The mission was planned during Operation Desert Shield after coalition planners identified Iraqi early-warning radar sites as a key part of Iraq's air-defense network. Army University Press says the final approved option paired Pave Low helicopters for navigation and terrain-following support with AH-64 Apaches for the strike, because the Apaches carried Hellfire missiles, Hydra-70 rockets, and 30 mm guns suited to destroying hard and soft targets at the radar sites.
On the night of January 16-17, 1991, the White and Red Apache teams launched from Al Jouf Airfield and crossed into Iraq with their Pave Low guides. Air Force Special Operations Command's history account says the Allied air offensive began at 2:20 a.m. on January 17, with four MH-53J Pave Lows followed by eight U.S. Army AH-64A Apaches from the 1st Battalion, 101st Aviation Brigade.
The attack destroyed the radar-site targets before the wider coalition strike packages entered Iraq. The AFSOC account says the Apaches fired 27 missiles, around 100 70 mm rockets, and about 4,000 rounds of 30 mm ammunition in less than two minutes, while Redstone Arsenal's historical summary separately records eight Apache helicopters using Hellfire missiles and Hydra-70 rockets to destroy two Iraqi early-warning ground-control radar sites.

Operational role
In this conflict-use record, the Apache's documented role was a low-level night deep attack against fixed Iraqi air-defense infrastructure, not a general claim about every Apache mission in the Gulf War. The mission objective was to blind part of Iraq's early-warning network and open a route for follow-on coalition aircraft during the first minutes of Operation Desert Storm.
The available official sources identify the user as U.S. Army AH-64A crews from the 101st Aviation Brigade, operating as part of a joint task force with Air Force special operations helicopters. They connect the aircraft's use to Hellfire missile, Hydra-70 rocket, and 30 mm gun employment against early-warning radar, communications, generator, and related site targets.
