The Pentagon is expanding its counterdrug operations in the Western Hemisphere as part of a growing regional campaign against cartel networks, Secretary of War Pete Hegseth announced Thursday.
The effort, known as Operation Southern Spear, is shifting into a broader phase that will rely heavily on unmanned and autonomous systems to track and stop narcotics trafficking that U.S. officials say threatens national security.
Hegseth shared the updated mission in a post on X, calling the operation a direct response to drug networks fueling overdoses in the United States.
“Today, I’m announcing Operation SOUTHERN SPEAR,” he wrote. “Led by Joint Task Force Southern Spear and @SOUTHCOM, this mission defends our Homeland, removes narco-terrorists from our Hemisphere, and secures our Homeland from the drugs that are killing our people. The Western Hemisphere is America’s neighborhood – and we will protect it.”
The Trump administration has taken a more aggressive role in recent months, arguing that transnational criminal groups across Latin America are driving violence and drug flows that require a response. Regional governments, including Colombia, have agreed on the need for more maritime security cooperation.
Operation Southern Spear began earlier this year but is now evolving into a long-term mission focused on deploying unmanned surface vessels, robotic interceptor craft and vertical takeoff unmanned aircraft across the U.S. Southern Command region.
Cmdr. Foster Edwards, the 4th Fleet’s Hybrid Fleet director, said earlier that the initiative aims to move beyond short-term testing and instead operationalize how unmanned platforms can support the detection and monitoring of illicit trafficking.
U.S. 4th Fleet will integrate these systems with Coast Guard cutters and operations centers at both 4th Fleet and Joint Interagency Task Force South. Officials say the effort will help determine how manned and unmanned assets can be combined to maintain maritime awareness and carry out sustained counternarcotics missions.
The Navy says Southern Spear aligns with Project 33, a broader initiative to integrate robotic systems throughout the fleet. U.S. officials argue that greater unmanned coverage in major shipping corridors can bolster decision-making and strengthen cooperation with partner navies. Countries such as Panama and Ecuador have publicly supported increased maritime monitoring as a way to restrict cartel movements.
