See how narco subs use simple materials to bypass complex naval surveillance systems.

This breakdown explores the engineering behind these vessels, designed to ride just below the surface and minimise their radar signature. We analyse the cat-and-mouse game between smugglers and the authorities using basic stealth technology to evade radar detection.

00:00This isn't a military submarine. It's a homemade boat carrying 7 tons of cocaine, and it's designed to be completely
00:06invisible to Navy radar.
00:07It's not made of high-tech steel or titanium. It's built from fiberglass and wood, materials that don't reflect radar
00:13waves like a warship does.
00:15But the real trick isn't the material, it's the freeboard.
00:18The hull is engineered to ride almost completely submerged, with only a tiny, non-metallic profile poking above the waves.
00:24Radar works by bouncing energy off objects. By keeping the boat awash, it blends into sea clutter, the natural noise
00:31of waves and spray.
00:32To a Navy radar operator, this massive vessel looks like nothing more than a rogue wave or a piece of
00:37floating debris.
00:38They even route the exhaust through cooling pipes to kill the heat signature, making it invisible to infrared sensors, too.
00:44It's the ultimate game of hide-and-seek. Authorities aren't fighting a machine, they're fighting a shadow that's engineered to
00:50disappear into the ocean itself.
