What is known about foreign components in missiles

Earlier, the Main Intelligence Directorate published a list of foreign companies that supply Russia with chips for missiles it launches against Ukraine. To guide missiles, Russia uses its own 1982 development called GLONASS. It is a kind of analog of GPS. GLONASS depends on microchips produced by foreign companies: Linx Technologies (USA); Broadcom (USA); Qualcomm (USA); Telit (USA); Maxim Integrated (USA); TRIMBLE (USA); Cavli Wireless (USA); u-blox AG (Switzerland); STMicroelectronics (Switzerland); Sierra Wireless (Canada); NovAtel (Canada); Septentrio (Belgium); Antenova (UK).

Russia purchases these microchips through numerous front companies.

On June 14, the head of the President's Office, Andriy Yermak, said that each missile fired by Russia at Ukrainian cities has 40 foreign components.

NSDC Secretary Oleksiy Danilov also reported that Russia could have purchased foreign parts for missiles before the full-scale invasion of Ukraine.

On July 24, Politico reported that China may be secretly supplying Russia with non-lethal equipment and dual-use goods for its army, according to customs documents.

In its investigation, the Russian publication Verstka found that in the last six months alone, Russia has imported more than half a billion dollars worth of banned chips from Western companies, which are used, in particular, for weapons production. Millions of dollars worth of machine tools for the defense industry and USD 171 million worth of Western spare parts for civil aviation.
