Russia evades Ukraine electrical substation defences with small, unjammable drones

In a surprising tactical shift, Russia has deployed small drones that operate via fiber-optic cables, allowing them to evade Ukrainian defenses and strike high-voltage electrical substations in Sumy. These drones are proving difficult to jam, highlighting a new dimension in the conflict's technological warfare. This development underscores the escalating sophistication of both sides' military strategies, with potential implications for civilian infrastructure and energy security across the region. The use of such drones signals a more insidious approach to warfare, raising concerns about future attacks on critical infrastructure.
