A closer look

South American drug cartels privately fund and construct fully functional fiberglass submarines deep within the jungle canopy to transport tons of illicit narcotics across the ocean completely undetected by naval radar. These self-taught engineers build surprisingly sophisticated semi-submersible vessels equipped with diesel engines, navigation electronics, and enough life support to keep desperate crews breathing while traveling thousands of miles underwater. While legitimate defense contractors spend billions of taxpayer dollars and decades of research to develop military stealth technology, a bunch of heavily armed outlaws in a swamp managed to hack together viable covert submarine fleets using duct tape, outboard motors, and sheer financial motivation. It really makes you question the bloated budgets of modern navies when a cartel logistics department can achieve trans-oceanic stealth capabilities with the engineering equivalent of a high school science fair project
