Underwater drones capable of passing from Morocco to Spain through the Strait of Gibraltar with 200 kilos of drugs on board.
This is the discovery recently made by the Spanish police.
Authorities announced on Monday July 4 that they had got their hands on three of these devices for the first time, similar to mini sheet metal submarines or a small surfboard.
Two were in the making and the last one was almost finished.

These drones "were to be delivered to French drug traffickers for the transport of large quantities of cocaine", explained the police in a press release.
Submersible and remotely steerable, these drones have a range of approximately 50 kilometers.
"The navigation of these devices was done via GPS, so that a person or a member of the organization could check the mooring location at any time from their home with a tablet and a suitable program", details Juan Antonio Siloleo Head of the Narcotics Squad.
