Royal Marine Commandos boarded a Russian shadow fleet oil tanker in the English Channel on June 14 in a six-hour operation, the first of its kind by UK armed forces. The vessel, Smyrtos, carries sanctioned Russian oil as part of a fleet of over 700 ships that transport 75% of Russia’s oil exports. The UK has sanctioned more than 500 vessels and now has legal power to intercept them in British waters.
How the Boarding Happened
Royal Marine Commandos fast-roped from a helicopter onto the Smyrtos in the early morning hours. National Crime Agency officers and RAF support joined the operation in international waters more than 12 nautical miles from the UK coast. The boarding lasted six hours and involved searching cabins and inspecting paperwork aboard the vessel.
What the Shadow Fleet Does
Russia operates over 700 shadow fleet vessels to evade international sanctions on its oil exports. These ships carry 75% of Russia’s sanctioned oil and provide a critical lifeline for funding the Kremlin’s war in Ukraine. The UK has sanctioned more than 500 of these vessels and banned them from UK ports. British firms and individuals face legal restrictions from providing financial, insurance, or brokerage services to these ships.
Arrest and Investigation
National Crime Agency officers arrested an Indian national, 38, on suspicion of sanctions offences under the Russia Regulations. The crew of 24 Georgian and Indian sailors remained aboard and assisted with the investigation. The vessel was anchored off the Dorset coast pending further investigation. The Smyrtos had sailed from Russia’s Ust-Luga port on June 5 before crossing into the Channel on June 14.
UK Authority and International Response
Prime Minister Keir Starmer announced in March that British armed forces gained the power to board sanctioned vessels in UK waters. Starmer called the operation “yet another blow to Russia” and a reminder that those funding Putin’s war “will not let them hide.” Russia has previously described similar interceptions as illegal and “bordering on international piracy.” Moscow had not issued an official response as of June 15.
Final Thoughts
The UK’s first armed boarding of a Russian shadow fleet tanker demonstrates expanded enforcement against sanctions evasion. With over 500 vessels sanctioned and legal authority to intercept them, the UK is tightening pressure on Russia’s oil trade.
