Chips in Russian weapons: Ukrainians sue US semiconductor companies

The ongoing Russian war of aggression against Ukraine not only has military and humanitarian consequences, but also raises legal questions about the responsibility of Western technology companies. Ukrainian civilians have filed lawsuits in the USA against several major semiconductor manufacturers because they believe that modern Western chips were used in Russian weapons systems that were used in attacks on the civilian population despite existing sanctions. The proceedings are directed against Intel, Advanced Micro Devices and Texas Instruments, among others, and were brought before federal courts in the US state of Texas.

According to the plaintiffs, the lawyers represent dozens of victims who were injured or lost family members in Russian missile and drone attacks between 2023 and 2025. The pleadings name several specific attacks in which KH-101 cruise missiles, Iskander missiles and unmanned aerial vehicles are alleged to have been used. Electronic components associated with products of the defendant companies were identified in individual debris finds. The plaintiffs argue that these components were used for control, navigation or target acquisition and therefore played a key role in the weapons’ operational capability.

At the heart of the allegation is what the plaintiffs see as insufficient compliance with and enforcement of existing export controls. The companies are accused of not having sufficiently tightened their control mechanisms despite the known risks of circumventing transactions via intermediaries, front companies and third countries. The complaints speak of deliberate ignorance and corporate negligence, as internal inspection processes and supply chain monitoring did not prevent sensitive technology from ultimately ending up in Russia or allied states such as Iran. Responsibility is not only attributed to direct deliveries, but also to indirect onward transfers via complex trading structures.

Intel has publicly denied the allegations and declared that it had terminated all business relationships in Russia and Belarus after the start of the war. The company emphasizes that it strictly complies with US export laws and all applicable sanctions. AMD and Texas Instruments have also stated in previous statements that they do not support the military use of their products in Russia and maintain internal compliance programs. At the time of reporting, however, not all of the defendant companies had issued any current statements on the specific lawsuits.

In addition to the chip manufacturers, some of the lawsuits are directed against the electronics distributor Mouser Electronics from Texas, which belongs to the Berkshire Hathaway Group. The company is accused of having played a central role in the resale of the components in question, including through deliveries to customers allegedly controlled by Russian front men. Mouser has announced that it will only comment on the allegations as part of the legal proceedings.

Independent research and investigations by government agencies had previously shown that Western sanctions were unable to completely prevent the flow of modern semiconductors into the Russian arms industry. Political decision-makers in the USA have also repeatedly called on manufacturers and distributors to monitor their supply chains more closely and to close possible circumvention channels more consistently. One of the reasons for the choice of Texas as the place of jurisdiction is that several of the companies involved have their headquarters or significant operational branches there.

Conclusion

The lawsuits filed by Ukrainian civilians against US semiconductor manufacturers mark a new legal dimension of the war in Ukraine, in which economic responsibility and civil liability are coming into focus. Regardless of the outcome of the proceedings, they highlight the ongoing difficulties in enforcing international sanctions and the central role of modern technology in current military conflicts. Whether and to what extent companies can be held liable for indirect supply chains will now be the subject of judicial review.
