Borderland Beat: Mexican Cartel Unmanned Aerial Vehicles (Narco Drones)
Mexico’s drug cartels are reportedly commissioning custom-made drones to transport narcotics across the US border, illustrating the continual development of innovative new technologies and methods used to traffic drugs.
While cartels used to use foreign-made drones, the new reliance on home-grown technology and construction is more cost-effective -- the method is cheaper than the construction of cross-border tunnels or the use of semi-submersible vessels, according to El Universal's report.
Mexican criminal organizations have been using UAVs since at least 2010, but the relatively small amount of drugs transported per trip on the drones registered by the DEA helps explain why the cartels want to develop larger, specially tailored UAVs. As drone technology worldwide becomes increasingly accessible and cost effective, commissioning custom-made drones in Mexico is the next logical step for cartels.
