Russian Shadow Fleet Deploys Spy Drones Over Critical UK and European Infrastructure

Intelligence analysts have linked uncrewed aerial systems that have flown over infrastructure—including energy sites and undersea cables—in the UK, Germany, France, Denmark, Belgium, Ireland, Spain and Norway to the movements of Russian-owned oil tankers transiting the English Channel and the North Sea.

The shadow fleet of 1,300 tankers—generating roughly £156 million for the Kremlin—has been described as a ‘hybrid warfare platform.’ Security personnel, including Wagner operatives, are placed aboard to guard crews and enable drone, missile and surveillance launches while communications are encrypted and beacons disabled.

ACLED logged 56 drone incidents in the last 18 months—an 80 % rise from 31 in the prior three years—and four Baltic-Sea cable damages since early 2023. Windward reported a 153 % jump in Baltic drifting activity in 2024, and Europe has seized nine shadow-fleet tankers, including Boracay.

British commandos seized an illegally flagged tanker in the English Channel in May; the Russian vessel Yantar illuminated an RAF aircraft with lasers, prompting a UK engagement review. France seized Boracay off Brittany for suspected drone launches over Denmark, and Germany raided Scanlark, recovering GPS antennas and 360-degree cameras after a drone over-flight.
