Authorities in Awe of Drug Runners' Jungle-Built, Kevlar-Coated Supersubs

The group summed up its findings in a 70-page white paper—marked FOUO, for official use only—that conveys a grudging respect for the engineers and craftsmen who were able to build something so seaworthy in the middle of a swamp. “The streamlined hull, diesel-electric propulsion system, and fuel ballast system design all show a significant level of technical expertise and knowledge of submersible operations,” it states. The hull, they discovered, was made from a costly and exotic mixture of Kevlar and carbon fiber, tough enough to withstand modest ocean pressures but difficult to trace at sea. Like a classic German U-boat, the drug-running submarine uses diesel engines on the surface and battery-powered electric motors when submerged. With a crew of four to six, it has a maximum operational range of 6,800 nautical miles on the surface and can go 10 days without refueling. Packed with 249 lead-acid batteries, the behemoth can also travel silently underwater for up to 18 hours before recharging.
