UK Seizes Sanctioned Russian Oil Tanker Smyrtos in English Channel
On Sunday, June 14, 2026, a squad of Royal Marine Commandos, supported by the National Crime Agency, the Royal Navy, and an RAF P‑8 patrol aircraft, boarded the oil tanker Smyrtos in the English Channel, marking the United Kingdom’s first military raid of its kind.
The Smyrtos—flagged to Cameroon—had been anchored off Weymouth when the operation commenced. Ministry of Defence tracking data shows the vessel left Russia’s Ust‑Luga oil terminal on June 5, entered the Channel on Saturday, and subsequently changed both its name and flag after sanctions were imposed in July 2025. The tanker is part of Russia’s so‑called “shadow fleet,” a network that uses complex ownership structures and flags of convenience to transport oil while attempting to evade the sanctions triggered by the war in Ukraine.
The six‑hour raid began with commandos fast‑ropping from a helicopter that hovered low over the sea. Once aboard, the team conducted thorough searches throughout the ship. Royal Navy frigates HMS Sutherland and HMS Ledbury, the RAF P‑8 surveillance aircraft, and Maritime Air Group assets provided additional support. Former Armed Forces Minister Al Carns noted that the raid required personnel to fly at low altitude and to board the vessel swiftly from a helicopter.
Prime Minister Keir Starmer praised the operation in a post on X, calling it “a successful operation that delivers yet another blow to Russia” and emphasizing that the UK would not allow those who fuel Putin’s war in Ukraine to hide. Ukrainian President Volodymyr Zelensky also welcomed the seizure, describing it as an “important step” against Russia’s oil‑export network.
The UK has sanctioned almost 600 vessels linked to the shadow fleet. The Ministry of Defence said the Smyrtos is now being held off the south coast of England while authorities continue their investigation. No casualties were reported, and the cargo on board has not yet been disclosed.
The seizure follows a similar operation by French authorities, who intercepted another sanctioned tanker believed to be linked to the shadow fleet. The UK and France coordinated the raid, underscoring the broader effort by Western governments to enforce sanctions and disrupt the flow of Russian oil.
Under the 2022 Russian crude oil price‑cap sanctions, the UK and other G7 members have limited the value of Russian oil exports. These sanctions have reduced Russia’s oil revenues by 27 % compared with October 2024, the lowest level since the invasion began. The Smyrtos raid is part of the UK’s strategy to prevent sanctioned vessels from transporting oil that could fund the conflict.
The vessel’s status remains uncertain. The Ministry of Defence has not announced whether the ship will be returned to its owners, whether its cargo will be seized, or whether legal proceedings will be initiated. The investigation will determine whether the tanker violated UK or international law and whether additional sanctions or enforcement actions are warranted.
The operation demonstrates the UK’s willingness to deploy military and law‑enforcement resources to enforce sanctions and protect maritime security. It also signals to other sanctioned vessels that attempts to evade detection will be met with swift action.
As the investigation continues, authorities will decide on further steps, including potential legal proceedings, seizure of cargo, and coordination with international partners. The outcome will influence future enforcement of sanctions against the shadow fleet and the broader effort to limit Russia’s ability to finance its war in Ukraine.
