Remember this story we posted last week? The one about one of the seminal moments in the history of the United States Coast Guard, where the proud branch successfully intercepted an unmanned submarine in the Pacific Ocean containing about 16,000 pounds of cocaine worth an estimated $181 million?

Yeah, well the USCG just released video footage of the bust, taken from boats on the water and helicopters circling over the narcotic-stuffed, semi-submersible and it’s quite a thing to watch. According to them, the guardsmen pulled about 12,000 pounds from the vessel before it sunk to the ocean floor, about 200 miles south of Mexico.

According to The New York Times, the Sinaloa Cartel — headed by fan favorite and human groundhog “El Chapo” — has been using these ocean-going, torpedo-shaped sea crafts for years:

The Sinaloa has always distinguished itself by the eclectic means it uses to transport drugs. Working with Colombian suppliers, cartel operatives moved cocaine into Mexico in small private aircraft and in baggage smuggled on commercial flights and eventually on their own 747s, which they could load with as much as 13 tons of cocaine. They used container ships and fishing vessels and go-fast boats and submarines — crude semi-submersibles at first, then fully submersible subs, conceived by engineers and constructed under the canopy of the Amazon, then floated downriver in pieces and assembled at the coastline. These vessels can cost more than a million dollars, but to the smugglers, they are effectively disposable. In the event of an interception by the Coast Guard, someone onboard pulls a lever that floods the interior so that the evidence sinks; only the crew is left bobbing in the water, waiting to be picked up by the authorities.
