Check out this amazing video showing crew members from the U.S. Coast Guard Cutter Munro (WMSL 755) board a self-propelled semi-submersible suspected of smuggling drugs.

According to the Coast Guard, the incident took place June 18, 2019 while operating in international waters of the Eastern Pacific Ocean. The Coast Guard notes that purpose-built vessels such as this are designed to hold large quantities of contraband while evading detection by law enforcement authorities.

As our good friend Michael Carr points out, it just goes to show the enormous challenge the Coast Guard now faces in tracking down drug smuggling submarines in the open ocean. “And then jumping onto these submarines while they are underway…..Semper Paratus!”
