British armed forces have played a crucial supporting role in a French-led operation to intercept and board a vessel identified as part of Russia's so-called "shadow fleet," Defence Secretary John Healey confirmed. The operation targeted the oil tanker Deyna in the Mediterranean, a ship sanctioned by both the UK and the European Union for its involvement in transporting Russian oil.
Disrupting Russia's Sanctions Evasion Network
The shadow fleet comprises vessels used by Russia to circumvent international sanctions imposed following Vladimir Putin's invasion of Ukraine. These ships transport Russian oil and goods globally, generating revenue that funds Moscow's war effort. Defence Secretary Healey emphasized that disrupting this network remains a top priority for the British government.
"Disrupting, deterring and degrading Russia's shadow fleet – and starving Putin's war machine of funds – is a priority for this Government and we will continue to take action alongside our allies," Healey stated. "As threats increase and demands on defence rise, I am proud of the support our UK armed forces provided to this French operation, keeping Britain safe at home as we support Ukraine, deter Russia and deliver defensive operations in the Middle East."
French Leadership in the Mediterranean Operation
The French navy executed the interception of the Deyna, with British patrol boat HMS Cutlass providing vital monitoring, tracking, and imagery capture support near the strategic Strait of Gibraltar. French President Emmanuel Macron reinforced the commitment to targeting these vessels, despite other global conflicts.
"The war involving Iran will not deflect France from its support for Ukraine, where Russia's war of aggression continues unabated," Macron declared. "These vessels, which evade international sanctions and violate the law of the sea, are profiteers of war. They line their pockets while helping finance Russia's war effort. We will not allow it."
Growing International Cooperation Against Shadow Fleets
This operation represents the latest example of enhanced UK collaboration with allies to target sanctioned vessels. In January, British forces assisted the United States in seizing the oil tanker Marinera, previously known as the Bella-1, in the Atlantic. RAF aircraft and the British supply ship RFA Tideforce supported that mission.
Later the same month, Royal Navy patrol boat HMS Dagger aided French authorities in seizing another sanctioned ship, the Grinch, in the western Mediterranean, shadowing it through the Strait of Gibraltar.
Strategic Discussions and Future Actions
The UK has been actively advocating for increased seizures of shadow fleet vessels among allied nations. Earlier this month, Defence Secretary Healey and the Attorney General convened meetings with senior officials from other countries to explore both military and legal avenues for intensifying these efforts.
Despite this growing involvement, British forces have not yet conducted a boarding operation on a sanctioned vessel themselves. The support role in the Deyna operation underscores the UK's commitment to multilateral approaches in countering Russian sanctions evasion.
The continued targeting of shadow fleet ships reflects a broader strategic effort to economically pressure Russia by cutting off vital revenue streams derived from illicit oil shipments. As international cooperation strengthens, further operations are anticipated in key maritime corridors like the Mediterranean and Atlantic.
