International Operation “El Dorado”
In a major maritime security operation named “El Dorado”, Portuguese authorities intercepted a narco-submarine in the Atlantic Ocean transporting over 1.7 tons of cocaine bound for the Iberian Peninsula. The Portuguese Judicial Police (PJ) and the Portuguese Navy, supported by the United Kingdom and the United States, conducted the operation as part of an international effort to combat transatlantic drug trafficking. The semi-submersible vessel, carrying four crew members, was stopped before reaching European waters. According to the PJ, the final destination of the cocaine was “several European countries,” though the origin of the vessel and the nationality of the suspects have not been disclosed.
A coordinated transatlantic effort
Operation El Dorado involved multiple agencies, including the Portuguese Air Force, the U.K.’s National Crime Agency (NCA), the U.S. Drug Enforcement Administration (DEA), and the Joint Interagency Task Force South (JIATF South). This collaboration reflects the growing emphasis on international maritime coordination to counter drug-smuggling networks operating across the Atlantic. The seizure is among the largest in recent years and underlines Portugal’s strategic position as a key maritime corridor between Latin America and Europe.
The interception of this narco-submarine strengthens Portugal’s reputation as a frontline actor in European maritime interdiction operations. As criminal organisations increasingly turn to semi-submersible vessels to evade detection, international partnerships like El Dorado remain crucial to safeguarding Atlantic sea-lanes and curbing cocaine flows into the European market.
