India just seized three tankers of the "shadow fleet" carrying Russian oil. The US has seized, how many? Has any other nation seized any? And how many ships are estimated to be in the "shadow fleet"?
Here's the most recent, verified picture of seizures of "shadow fleet" tankers (vessels used to carry sanctioned oil, especially Russian, Iranian, and Venezuelan crude) and estimates of the overall fleet size:
🇮🇳 India's Seizure
India's coastal authorities seized three tankers this month that were U.S.-sanctioned (linked to Iranian oil smuggling) and considered part of the broader "shadow fleet."
🇺🇸 U.S. Seizures and Interdictions
The United States has seized at least one major Russian-flagged tanker (the Marinera, formerly Bella-1) following pursuit across the Atlantic.
U.S. forces have also intercepted or boarded additional vessels in 2026 (such as the Aquila II and Veronica III) connected to sanctioned oil shipments, though not all ended in formal legal "seizures" yet.
Altantic Council reporting suggests the U.S. has seized at least ~7 vessels linked to shadow fleet activity, including older enforcement efforts tied to Venezuelan oil sanctions.
So, the concrete number of U.S. seizures is at least 1 – 7, depending on how broadly you count enforcement actions versus formal seizures processed in U.S. courts.
📌 Other Nations
France and other European navies have detained or intercepted "shadow fleet" tankers in the Mediterranean.
Germany and Estonia have seized or detained vessels suspected of shadow-fleet activity in prior years.
These are fewer and generally smaller scale compared to recent U.S. and Indian actions.
🛳 Estimated Size of the Shadow Fleet
Estimates vary, but multiple sources put the global shadow fleet at a very large scale:
About 900 – 1,500 tankers worldwide are considered part of the "shadow fleet" or dark fleet moving sanctioned oil.
Wikipedia estimates around 1,100 – 1,400 vessels (across oil tankers and other ships) associated with Russia's shadow transport network.
Earlier figures (e.g., 2022 baseline) described ~600 vessels, but this has grown significantly since sanctions were imposed.
In summary:
🇮🇳 India seized 3 shadow fleet tankers.
🇺🇸 The U.S. has seized at least one major tanker and possibly up to ~7 vessels connected with shadow oil shipping, with additional interdictions under way.
🇪🇺 Other nations (EU states) have also detained or seized some vessels in previous crackdowns.
🌍 The shadow fleet is estimated to include roughly 900–1,500 ships globally.
