British Forces Intercept Suspected Russian “Shadow Fleet” Oil Tanker in English Channel

British armed forces have intercepted a suspected Russian “shadow fleet” oil tanker in the English Channel during a major six-hour operation in the early hours of Sunday morning.

The vessel, identified as Smyrtos, was boarded by Royal Marine Commandos alongside specially trained officers from the National Crime Agency (NCA), with support from Royal Air Force assets and Royal Navy vessels.

According to a statement from the Ministry of Defence (MoD), the tanker has since been detained and will remain under close monitoring off the coast of Weymouth while investigations continue.

The operation involved aircraft from the Maritime Air Group, an RAF P-8 Poseidon maritime patrol aircraft, as well as Royal Navy warships HMS Sutherland and HMS Ledbury, highlighting the scale and coordination of the mission.

Prime Minister Sir Keir Starmer welcomed the successful interception, describing it as a significant step in efforts to disrupt Russia’s ability to fund its war in Ukraine.

He said: “This successful operation delivers yet another blow to Russia and reminds those fuelling Putin’s war in Ukraine that we will not let them hide.”

Defence Secretary Dan Jarvis echoed those remarks, stating: “Russia relies on its shadow fleet to fund their conflict in Ukraine and our interdiction delivers a blow to Putin’s illegal war.”

Russia has increasingly relied on what has become known as a “shadow fleet” – a network of ageing tankers operating under foreign flags and often using complex ownership structures – to transport oil and petroleum products while attempting to circumvent international sanctions imposed following the invasion of Ukraine.

According to maritime tracking website MarineTraffic, Smyrtos is currently listed as sailing under the flag of Cameroon and is anchored within the English Channel.

Authorities have not yet disclosed the full findings of their investigation or whether any arrests have been made. The tanker is expected to remain under observation off the Dorset coast while officials examine its activities, cargo, and compliance with international sanctions.

The operation marks one of the most high-profile maritime interdictions conducted by UK authorities in recent months and demonstrates the government’s continued commitment to enforcing sanctions against Russia and disrupting financial networks linked to the ongoing conflict in Ukraine.

Further updates are expected as the investigation progresses.
