In the 1990s, rumors began to spread that the Colombian cartels were moving cocaine to the United States by submarine. In 2006 the navy intercepted a “narco-sub” off Costa Rica with 3.5 tonnes of cocaine on board. In 2019, thirty-three submarines were intercepted by Colombian authorities, an average of almost three a month, most of them along the Pacific coast.
The Guardian quotes Admiral Hernando Enrique Mattos Dager, in charge of Colombia’s Poseidon taskforce against drug trafficking, saying, “Large quantities of cocaine are transported by sea,” he said. “It is much easier to move a tonne of cocaine by sea than by plane because there are more checks on freight at airports.” He estimates that 80% percent of the country’s illicit drugs leave via the Pacific coast and 14% go via the Caribbean.
