Five individuals were on board the vessel, and the Coast Guard seized around 17,000 pounds of cocaine worth an estimated $232 million, the spokesperson said.
U.S. Vice President Mike Pence met members of the elite Coast Guard team who participated in the seizure as the drugs were unloaded in San Diego on Thursday.
The chase and seizure took place in global waters in the Eastern Pacific Ocean on 18 June. The video shows one boat pulling up alongside the sub while a coast guard officer shouts at the suspected smugglers in Spanish.
Dramatic footage has been released of a USA coast guard member pouncing onto a homemade submarine as it threatens to descend below the ocean's surface.
According to the press release on Thursday, during these months a total of 39,000 pounds of cocaine and 933 pounds of marijuana were caught, the equivalent of $569 million. He tweeted extensively about the "courageous service" of the Coast Guard helping to save lives. "I think there's no question, that as we continue to secure our border, we're going to see the drug cartels use the open ocean to move narcotics more than they do today". Coast Guard patrols may encounter a narco sub about once a year.
It was ultimately bound for the United States, as the vessel had been tracked by a Coast Guard surveillance aircraft. "And that's why we are committed to fully funding our Coast Guard, including replacing old ships with new ones, just like the Cutter Munro". The Coast Guard, along with other American agencies and their counterparts in allied nations, most often precede these interdictions with extensive reconnaissance coordinated through the Joint Interagency Task Force-South, based in Key West, Florida.
