Direct proof of use
AGM-88 HARM use in the 1990 Gulf War is documented in air-campaign studies and Marine Corps operational history. A CSIS-hosted Gulf War chapter states that coalition forces used 2,151 anti-radiation missiles during Desert Storm, including 2,039 U.S. HARM and other anti-radiation missiles, and says almost all of the U.S. anti-radiation missiles were HARMs because older Shrikes lacked the range needed against Iraqi air defenses.
Marine Corps University history describes escort F/A-18s launching HARMs at Iraqi radar equipment on the first day of Desert Storm and records that Marines fired 100 HARMs at Iraqi radars that day, alongside hundreds more fired by other coalition aircraft.

Timeline
On January 17, 1991, the opening day of Operation Desert Storm, Marine F/A-18 escorts fired HARMs at Iraqi radar equipment during the early air attacks. The same Marine Corps history says those first-day Marine launches totaled 100 HARMs.
Across Desert Storm, coalition use of anti-radiation missiles was concentrated in suppression of Iraqi radar-guided air defenses. The Gulf War chapter attributes 1,120 U.S. anti-radiation missile launches to the U.S. Air Force, 679 to the U.S. Navy, and 240 to the U.S. Marine Corps, while noting that almost all of the U.S. total consisted of HARMs.

Narrative
In Desert Storm service, the AGM-88 HARM functioned as a coalition suppression-of-enemy-air-defenses weapon rather than a general-purpose strike missile. Its documented target set was Iraqi radar equipment and active radar emitters tied to Iraq's integrated air-defense network. The Gulf War chapter links heavy HARM firing to reduced Iraqi radar activity and identifies F-4G Wild Weasel aircraft as roving surface-to-air missile killers that located and fired at active emitters.
The HARM role combined destructive and suppressive effects. The same Gulf War account says the first-night firing of about 200 HARMs changed Iraqi air-defense behavior and contributed to a sharp reduction in radar activity by the third day. It also records that the 35th Tactical Fighter Wing, described as the main Wild Weasel HARM-firing formation, fired 905 missiles and recorded 254 radars destroyed.
The AGM-88B Block III was the principal variant associated with the campaign in specialist designation references. Designation-Systems describes the AGM-88B Block III update as available from 1990 and says it was widely used in the 1991 Gulf War, with more than 2,000 HARMs fired at Iraqi radars. That supports the compact catalog claim about mass HARM employment while the campaign histories provide the operational context for who fired them and why.
