Via Reuters: Colombia finds homemade cocaine-smuggling sub | International

Colombian marines seized a makeshift submarine capable of smuggling up to 12 metric tons of cocaine through the Pacific to Central America, making it one of the largest such craft found, authorities said on Friday.

The nearly completed fiberglass submarine, found in a rural area in south Narino province, had space for four crew members, the Navy said in a statement.

This is the hardly the first:

Rudimentary submarines and submersible containers dragged behind container ships are among the more inventive transport methods used by traffickers. Since 2024, Colombia’s navy has captured 11 homemade submarines.

Indeed, I noted one of them back in August.
