  • Colombian authorities discovered this fully functional narco-submarine last year. The vessel could carry 8 tons of cocaine and has a range of 8,000 miles. The submarine is similar to the Navy's own tactical sub, except this one has an interior bathroom and larger beds, sailors said. Photo by / Juan Manuel Barrero Bueno

  • A semi-submersible, used for drug running, sits in a naval impound lot on Colombia's Pacific coast. When in operation, only the vessel's top cabin would have emerged from the water, making it difficult to detect. Colombia's Pacific is a hotbed for such narco-innovation.
