A fleet of roughly 20 illicit tankers tied to Iran, Venezuela, and Russia has been operating in the Caribbean, and a recent U.S. seizure of the sanctioned tanker “Skipper” has brought the issue into the spotlight, exposing how illicit oil trade can fund hostile regimes and terrorist networks.
What looked like another tropical news item has turned into a national security story. These so-called “Ghost Armadas” are not cruise liners or cargo ships you’d expect in a travel brochure; they’re tankers moving sanctioned oil in ways that threaten American interests. The pattern is clear and the connections run to Tehran, Moscow, and Caracas.
Monitoring groups report about 20 vessels involved, with 11 directly tied to Iran’s oil operations and the rest linked to Russian and Venezuelan activity. Names like ‘Skipper’ and ‘Star Twinkle 6’ appear on tracking lists, and satellite imagery shows vessels like ‘BERTHA’ loading Venezuelan crude at key terminals. That sort of proximity to U.S. shores raises obvious alarm bells for anyone watching the region.
United Against Nuclear Iran has been tracking these movements for over a decade, cataloging a web of transfers that evade sanctions and generate hard cash for hostile actors. The fleet’s coordination points to a deliberate effort to keep sanctioned oil flowing into global markets through opaque ship-to-ship transfers and darkened transponders. For policymakers this is not a regional curiosity — it’s a national security headache that requires a steady response.
The U.S. recently made a decisive move by seizing the tanker ‘Skipper’ off Venezuela’s coast in an operation that involved multiple agencies. Video footage released by U.S. Attorney General Pam Bondi on X shows armed agents in camouflage rappelling from helicopters onto the ship’s deck, a scene that underlines how seriously federal authorities view these operations. The takedown was carried out by the FBI, Homeland Security Investigations, and the Coast Guard with military backup.
This marks the first seizure of a Venezuelan oil cargo since sanctions took full effect in 2019, and it signals a stepped-up campaign against Nicolás Maduro’s regime. For Republicans and national security hawks, the action is the kind of firm enforcement that was overdue after years of lax attention. The message is simple: illicit oil networks will not operate with impunity near the Western Hemisphere.
The stakes go beyond crude prices or shipping routes; this trade bankrolls violent and destabilizing actors. UANI warns that revenue from ships like the ‘Skipper’ helps fund groups such as Iran’s Islamic Revolutionary Guard Corps and Hezbollah while shoring up hostile governments and feeding markets in ways that undercut free nations. “Iran is the largest state sponsor of terrorism and its illicit oil sales are the main source of funding for its global terrorist activities,” said Jemima Shelley, Senior Research Analyst at UANI, to the Daily Mail.
When oil money flows unchecked, it rarely buys innocuous things. It funds proxy forces, bankrolls repression, and deepens the reach of regimes hostile to the United States and our allies. Seeing these operations so close to home should sharpen the focus of any administration serious about cutting off financing for terrorism and coercive foreign powers.
At UANI, we have acquired data showing that there are at least 10 additional dark fleet vessels in the Caribbean with a similar history of transporting illicit Iranian oil. In total, these 10 vessels have in the past carried over 29 million barrels of Iranian crude, generating approximately $1.8 billion for the Iranian regime.
That figure — nearly $2 billion in potential revenue linked to illicit shipments — makes the problem impossible to ignore. It’s not just a statistic for analysts; it represents influence, arms, and operations that fuel instability across regions where the U.S. has strategic interests. Responsible enforcement and persistent tracking are the practical responses to that scale of illicit funding.
UANI officials indicate more vessels are on their radar, and U.S. authorities appear prepared for additional enforcement actions. The seizure of ‘Skipper’ shows that decisive measures can be executed when political will and interagency coordination align. The Trump administration’s tougher posture on disrupting these networks reflects a preference for direct action over idle diplomacy, and that approach is resonating with those who view illegal oil flows as an active national threat.
