Event Summary

Since May 2026, Russia has been using small fiber-optic FPV drones to bypass Ukrainian defenses and damage high-voltage electricity substations in Ukraine — Sumy Oblast. The Centre for Information Resilience verified four strikes on 330 kV substations and at least four on 110 kV substations, located 16-26 km from the frontline. The drones, costing as little as $2,000, are immune to electronic warfare and target autotransformers worth $3.5 million each. Ukrainian Defence Minister Mykhailo Fedorov stated the security situation deteriorated in June. The International — International Criminal Court has issued arrest warrants for senior Russian commanders for past grid strikes. Russia denies targeting civilians.
