Portuguese authorities, in a multi national maritime operation, recently intercepted a semi submersible vessel, commonly known as a "narco sub," in the mid Atlantic Ocean carrying more than 1.7 tonnes of cocaine destined for Europe. The successful seizure highlights the sophisticated methods employed by international criminal organizations and the ongoing efforts of global anti drug trafficking agencies.
The operation was conducted by the Portuguese Navy and the Judicial Police, acting on intelligence received from the Lisbon based Maritime Analysis and Operations Centre (MAOC N). The narco sub was located approximately 1,000 nautical miles (about 1,852 kilometers) off the coast of Lisbon, an area in the mid Atlantic that drug traffickers use to bypass closer coastal patrols. This route demonstrates the increasing ambition of cartels to deliver massive cocaine shipments directly to the Iberian Peninsula, which serves as a significant entry point for drugs into the broader European market.
Upon interception, authorities seized the 1,740 kilograms of cocaine and detained four crew members on board the vessel. The suspects included citizens from South American nations, specifically two Ecuadorians, one Venezuelan, and one Colombian. Officials noted that the crew members' different nationalities point to the wide ranging, multinational scope of the criminal organization behind the operation. Following their arrest, the suspects were remanded into pre trial custody in the Azores.
The operation received critical support and intelligence from international partners working within the scope of MAOC N, including the United States Drug Enforcement Administration (DEA) and the United Kingdom's National Crime Agency (NCA). This inter agency cooperation was crucial in tracking and locating the elusive vessel in the vast expanse of the Atlantic. The seized vessel, a semi submersible (SPSS) designed to travel just below the water's surface to evade detection by radar and visual means, was deemed too fragile to be towed back to port due to adverse weather and its delicate construction, and subsequently sank in the open sea. This incident marks the second such vessel intercepted by Portuguese authorities in 2025, following a March seizure of a narco sub carrying an even larger 6.5 tonnes of cocaine.
