Article does mention however that "it was being used for packages of narcotics, particularly cocaine". https://www.statista.com/chart/18527/cocaine-retail-steet-prices-in-selected-countries/ https://www.statista.com/chart/18527/cocaine-retail-steet-pr... shows 67 USD per gram, which means that if you've got 150kg of cocaine on board, the street value is just over ten million USD. I don't know how much of that would be profit, but seems quite likely there's an excellent cost vs reward ratio - potentially even so high that these drones could be used almost disposably if they are intercepted less frequently than boats.
