Counter-drug sea drones utilized by Navy as Trump ramps up military resources at the border

The operation will test the Navy's use of maritime drones, in its early stages, and apply lessons learned to missions all across the globe. 

Dubbed Operation Southern Spear, the Navy's 4th Fleet will use "a heterogeneous mix of Robotic and Autonomous Systems (RAS) to support the detection and monitoring of illicit trafficking while learning lessons for other theaters," a news release said on Monday. 

As President Donald Trump shuts down the U.S. southern and northern borders, smugglers are expected to look for alternative routes to carry out their illegal trafficking business. Human and drug trafficking cartels have increasingly turned to the nation's maritime borders to smuggle weapons, narcotics and people into the country.  

Included in the operation are 20 high-endurance Saildrone Voyager unmanned surface vehicles, equipped with a newly upgraded sensor suite, according to the press release. The vehicles are 10 meters long and can surveil thousands of square miles of water per day to look for smugglers. 

The drones have already sailed the Persian Gulf under the Navy's Hybrid Fleet Campaign and Project 33 and as part of Operation Windward Stack, operated by the 4th Fleet throughout 2024. They offer a 95% detection rate and are contractor owned and operated. This means that SailDrone operates the surveillance platform while the Defense Department purchases the data. 

"As land borders become more secure, traffickers will exploit maritime pathways more than ever. We're honored to serve, providing autonomous around-the-clock maritime surveillance to help stop smugglers before they reach our shores," said Tom Alexander, Saildrone VP of government relations. 

Utilizing U.S. military might to disrupt the flow of human and drug trafficking at the southern border has been a top priority for Trump.
