Ukraine Says Over 75% of Foreign Parts Found in Russian Kometa Anti-Jamming Tech Are American

Ukraine’s military intelligence agency, GUR, published a list of foreign parts it said were found in Russia’s 16-element Kometa modules. According to GUR, US-headquartered firms produced 28 of the 37 foreign components identified, or just over three-quarters of the listed parts. The systems are used to help Russian drones and ballistic missiles suppress electronic warfare and navigate.

The catalog identified components from 10 American brands, including digital processors from Intel subsidiary Altera, radio-frequency and precision components from Analog Devices, a memory chip from Micron, and supporting electronics from Texas Instruments. GUR also indicated that three components were built by Chinese companies, while six came from Japanese, Taiwanese, and Swiss manufacturers. Texas Instruments told Business Insider it “strongly opposes” the use of its chips in Russian military equipment and said any shipments of TI chips into Russia are illicit and unauthorized.

Kometa antenna panels are among the most common anti-jamming tools on Russian long-range weapons, including Shahed drones, Iskander-M ballistic missiles, and glide bombs. Each antenna receives satellite signals and helps counter jamming or spoofing. The 16-element Kometa, an array of 16 antennas, is one of Russia’s newer versions in mass production.

The findings come as electronic warfare grows more important to Ukraine’s air defense effort. Kyiv uses jamming tools and interceptors to counter Russian drone and missile attacks, while Moscow has begun mass-launching faster, jet-powered drones. The reported presence of foreign electronics in Russian military systems underscores the challenge of preventing commercial components from reaching sanctioned or military end users.
