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.

The most valuable feature, though, is the cargo bay, capable of holding up to 9 tons of cocaine — a street value of about $250 million.
