U.S. probing how American electronics wound up in Russian military gear

A team from a separate British group — the Royal United Services Institute, or RUSI, a defense-focused think tank — also traveled to Ukraine recently to inspect Russian equipment and to review teardowns conducted by Ukraine’s military. A single piece of radio-jamming equipment revealed computer chips from a dozen U.S. companies, including Intel, Analog Devices, Texas Instruments and Onsemi, according to a report RUSI published in April. The gear also contained components from half a dozen chipmakers in Europe, Japan and Taiwan. The radio-interference equipment, named Borisoglebsk-2, was designed to interrupt the enemy’s communications and was probably manufactured around 2015 or later, Nick Reynolds, one of the report’s authors, said in an interview.
