US Chipmakers' Parts Discovered in Russia's Advanced Anti-Jamming Systems

Ukraine’s military intelligence disclosed that the majority of foreign components found in Russia’s 16-element Kometa anti-jamming antenna modules originate from United States companies. Out of 37 identified parts, 28 were supplied by US firms, featuring Intel-Altera digital processors, Analog Devices radio-frequency and precision parts, a Micron memory chip, and supporting circuitry from Texas Instruments. Three components were traced to Chinese manufacturers, while six others came from Japanese, Taiwanese and Swiss sources.

The Kometa system, used on Shahed drones, Iskander-M missiles and glide bombs, helps Russian weapons resist jamming and spoofing. Texas Instruments said it opposes any illicit use of its chips in Russian military equipment. The disclosure comes as electronic warfare becomes increasingly critical to Ukraine’s air-defence strategy.
