Ukrainian units have begun deploying higher-speed drones in the Donetsk People’s Republic (DNR), significantly reducing their acoustic visibility, a representative of the regional FSB office told RIA Novosti.

According to the official, these systems include fast-moving UAVs, among them semi-copter-type devices powered by electric motors. Their increased speed makes them far harder to detect by sound, with the characteristic buzzing becoming noticeable only at the moment of impact.

The source added that such performance is not the result of entirely new designs, but rather upgrades to existing drone models.

At the same time, Ukrainian forces continue daily attempts to strike both border areas and central regions of Russia using fixed-wing kamikaze drones. Most of these aerial vehicles, the report notes, are intercepted and destroyed by Russian air defense systems.

In response, Russian forces carry out precision strikes targeting facilities involved in assembling Ukrainian drones, as well as defense industry sites, deployment points of Ukrainian units, and warehouses storing weapons and military equipment.
