What happened

Ukraine's Unmanned Systems Forces struck the Kuban-Crimea Energy Bridge — the main entry point for electricity supply from mainland Russia to occupied Crimea via four underwater cable lines converting to overhead lines at the PP-2 Crimea transition point near Hlazivka — disrupting that conversion system and cutting the peninsula's primary Russian power-supply corridor. The same overnight operation, involving USF's 412th Nemesis Brigade and 9th Kairos Battalion among other units, also struck five power substations (Nizhnyohirsk, Nasosna-3, Novotroitske, Kalynove and Troitske), three radar stations and a training/repair base. No casualty figures were published, and no independent damage assessment or Russian-side confirmation was cited.
