Authorities around the world are cracking down on drug traffickers using stealthy “narco subs”—homemade semi-submersible boats designed to move cocaine undetected across oceans.
In just the past few months, over 600 tons of cocaine have been seized globally, much of it linked to Colombia, the world’s top cocaine producer.
Recent highlights include:
Portugal (March): 6.5 tons found in a narco sub near the Azores Islands. Spain (January): A suspected sub broke in two while being towed to port. Mexico (November): Navy seized 8,000 pounds of cocaine off Acapulco. Colombia (this week): Over 6 tons found in a semi-sub and two underground stashes. U.S. Coast Guard: Offloaded over $54 million worth of seized drugs from the Pacific. Colombia (again): 3 tons intercepted after a sea chase near the Ecuador border.
Narco subs ride just above the water, avoiding radar and patrols. Though they can’t fully submerge, they’re highly effective — and increasingly common far beyond South America.
With global seizures climbing and smuggling tactics growing more advanced, the war on drugs is entering a new phase—one just barely breaking the surface.
