Russia reverts to US chips in Kinzhal missiles after domestic alternatives fail

Russia tried to build its way out of a chip shortage. It didn’t work.

Vladyslav Vlasiuk, Ukraine’s Presidential Commissioner for Sanctions Policy, revealed that Russia swapped out US-made Texas Instruments processors in its Kinzhal hypersonic missiles for domestically produced chips back in 2023. The substitution was supposed to be a sanctions-proofing move, a signal that Russia’s defense industry could wean itself off Western technology. But newer Kinzhal missiles recovered in 2026 tell a different story: the American processors are back.

The board that said it all

The evidence comes from a “Zarya-61” circuit board pulled from a Kinzhal missile that was shot down over Ukraine in May 2026. That board contained US-made processors, confirming that Russia’s homegrown replacements couldn’t match the performance standards required for one of its premier weapons systems.

Vlasiuk’s disclosure paints a picture of a defense industry caught between ambition and capability. Russia clearly recognized the risk of depending on foreign semiconductors and made a deliberate effort to develop alternatives. That effort failed. And rather than accept degraded missile performance, Russian weapons manufacturers went back to sourcing the components they actually needed, sanctions or not.

Foreign parts keep showing up

The Kinzhal board is far from the only evidence of continued foreign component dependency. Vlasiuk also pointed to a Geran-4 drone that was brought down on August 12, 2026. When Ukrainian analysts tore it apart, they found 96 foreign components inside. At least 21 of those parts were manufactured in 2025, with additional components bearing 2026 production dates.

That timeline matters enormously. These aren’t old stockpiles being burned through. Parts made in 2025 and 2026 are reaching Russian weapons factories despite an extensive international sanctions regime that has been in place for years.

One particularly striking detail from the examination: a single board contained a Texas Instruments processor dating back to 1986 alongside AMD microcircuits from 1996, sitting next to components manufactured between 2021 and 2024.

What sanctions can and can’t do

The broader takeaway from Vlasiuk’s briefing is that Western sanctions on dual-use semiconductors have created real friction for Russia’s defense industry. The failed domestic chip substitution in the Kinzhal program is proof that sanctions forced Russia into an uncomfortable position. But sanctions have not achieved a full cutoff. The continued appearance of freshly manufactured foreign components in Russian weapons systems suggests that procurement networks, likely running through intermediary countries and shell companies, remain active.

Vlasiuk framed the findings as evidence that foreign electronics remain critical to Russia’s weapons production. When your hypersonic missile program tries and fails to replace American chips, and your latest drones are still packed with nearly a hundred foreign components, “critical” might even be an understatement.
