U.S. defense officials publicly confirmed in August 2022 that the United States had supplied AGM-88 HARM missiles to Ukraine and that Ukrainian forces had successfully employed them from Ukrainian aircraft against Russian radar systems. In an August 19 background briefing, a senior U.S. defense official said Ukraine had integrated HARM missiles onto Ukrainian aircraft and used them to seek and destroy Russian radars. Five days later, Under Secretary of Defense for Policy Colin Kahl said the missiles had been adapted for launch from MiG-29 aircraft and that Ukrainian forces had recently used them to take out Russian radar systems.
Open-source reporting around the same period documented the unusual integration of a Western anti-radiation missile with Soviet-designed Ukrainian fighters. Breaking Defense reported comments by Gen. James Hecker, then commander of U.S. Air Forces in Europe, that contractors had equipped Ukrainian MiG-29 and Su-27 fighters with AGM-88 missiles in a matter of months. AeroTime separately reported Ukrainian Air Force video showing a MiG-29 carrying AGM-88 missiles and a visible launch in late August 2022.

Timeline
The first public U.S. acknowledgment came on August 8, 2022, when Kahl said recent U.S. drawdown packages had included anti-radiation missiles that could be fired from Ukrainian aircraft and affect Russian radars. On August 19, a senior defense official identified those weapons as HARM missiles, said Ukraine had already employed them, and described the August 2022 package as including additional HARMs. On August 24, Kahl linked the capability specifically to MiG-29 launch and recent Ukrainian use against Russian radar systems.
By September 2022, U.S. Air Force leadership was discussing the aircraft-integration effort publicly. Hecker said the adaptation had taken only a couple of months and involved Ukrainian Soviet-era MiG-29 and Su-27 fighters, while noting that the integration did not give those aircraft the full HARM capability available on an F-16.

Narrative
The AGM-88 HARM entered Ukrainian service as a Western air-launched counter-radar weapon added to Ukraine's existing fighter fleet rather than as part of a newly supplied Western aircraft package. U.S. officials described the transfer as a way to make Ukrainian aircraft already in service more effective during the ongoing war, and the August 2022 briefings tied the weapon's role to Russian radar systems rather than to general-purpose strike missions.
In Ukrainian use, the missile's documented function was suppression or destruction of Russian radar emitters associated with air-defense and other radar systems. The available official record separates three claims: the United States supplied HARM missiles to Ukraine, Ukraine integrated them on Ukrainian aircraft, and Ukrainian forces used them against Russian radars. Reporting from the same period added carrier-aircraft context, identifying Ukrainian MiG-29s and Su-27s as adapted launch platforms and documenting Ukrainian Air Force video evidence of MiG-29 HARM carriage and launch.
