Royal Marine Commandos and National Crime Agency officers boarded a sanctioned Russian oil tanker in the English Channel on June 14, making it the first time British forces have intercepted a shadow fleet vessel in domestic waters. The operation lasted six hours and was supported by the Royal Air Force.
The tanker, named the Smyrtos, is now being held off the southern coast of England as investigations continue. Prime Minister Keir Starmer confirmed the operation, framing it as a direct move to disrupt the network of aging tankers Russia uses to keep its oil revenue flowing despite Western sanctions.
What the shadow fleet actually is, and why it matters
After Western nations imposed sweeping restrictions on Russian oil exports following the invasion of Ukraine in 2022, Russia assembled a fleet of older, often poorly insured tankers that operate outside normal shipping channels. These vessels transfer oil between ships, obscure cargo origins, and deliver Russian crude to willing buyers at prices above the Western-imposed cap.
