Fiber-optic FPV destroys 330 kV transformer at Sumy; 1.5 bn-ruble damage claimed

Published 27 June 2026 · updated 28 June 2026

A Russian fiber-optic FPV unit designating itself ‘KVN’ claims to have penetrated a hardened shelter and destroyed a 330 kV autotransformer at the PS-330 Sumy substation, which they estimate at roughly 400 million rubles. Combined with three earlier transformer strikes at Sumy-region substations, cumulative economic damage is claimed to exceed 1.5 billion rubles. The fiber-optic link defeats the radio-jamming corridors that neutralise conventional RF-linked FPV drones.
