A Saildrone Voyager unmanned surface vehicle (USV), the only USV that has been continuously operating in support of Fourth Fleet since 2023, directly enabled an October 2025 drug bust during a Navy ship interdiction that seized more than $81 million worth of cocaine. This successful detection and interdiction is proof of Saildrone’s enduring and unmatched maritime domain awareness capability and reflects the ongoing work of Navy operators to integrate unmanned systems into daily operations.

“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,” said Saildrone President VADM (ret.) John Mustin. “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.”
