Saildrone USV enables US Navy interdiction of $81 million worth of cocaine

Saildrone has announced that one of its Voyager unmanned surface vehicles (USVs) directly enabled a U.S. Navy interdiction that seized more than $81 million worth of cocaine. The disclosure came alongside news that the Navy has awarded a $16.3 million task order to extend the fleet's time on station.

The company published both updates in a blog post on 4 August. The interdiction itself occurred in October 2025 and is being publicised now in conjunction with the new award, rather than at the time of the operation.

Task Order Details

The task order extends operations of the Voyager fleet in the Caribbean and Eastern Pacific in support of the U.S. Navy's counter-narcotics and counter-illicit trafficking efforts. The vehicles operate under:

• Joint Interagency Task Force South
• US Naval Forces Southern Command (also known as US Navy Fourth Fleet)

The Voyager fleet has been patrolling the region since 2023, covering waters near Panama, the Galapagos Islands, and the southern maritime approaches to the United States.

Operational Impact

Saildrone describes the Voyager involved as the only unmanned surface vehicle to have operated continuously in support of Fourth Fleet since 2023. The company presents the seizure as evidence that the capability is "not theoretical."

The company's value proposition centres on endurance: USVs capable of remaining on station for months at a time serve as both a deterrent and an early warning system. This frees crewed ships for interdiction operations, where Saildrone argues manned assets are most valuable.

Executive Statement

Saildrone President John Mustin, a retired US Navy vice admiral, said:

"The continuity of Saildrone's presence along the southern border for nearly three years demonstrates the strategic value we bring as the world's most experienced operators of unmanned surface vehicles. Our unmatched ability to remain on station and on mission in critical regions for months at a time is why our fleet serves as a powerful deterrent to bad actors. We look forward to continuing to partner with the Navy in its mission to secure the country's maritime approaches and southern border."

Integration and Capabilities

The company also highlighted its integration with Fourth Fleet operators and watchstanders over the same period, describing an operational environment in which crewed and uncrewed forces work together to maintain persistent maritime domain awareness.

Voyager Specifications

The Voyager is a 10-metre (33-foot) long-dwell unmanned surface vehicle built for persistent surface and subsurface surveillance. Beyond intelligence, surveillance, and reconnaissance (ISR), Saildrone says the platform can also conduct near-shore mapping and seafloor characterisation.
