Should the U.S. spend more on its military?
Saildrone, a maker of wind-powered autonomous ships with military surveillance systems, is expanding its European manufacturing into Norway, where Umoe Mandal will build its 65-foot Surveyor vessels. The company currently has approximately 75 unmanned surface vessels on mission across multiple ocean regions; this is an announced production expansion, not a new product launch.
Why it matters
The move places autonomous maritime surveillance production closer to European navies monitoring contested waters such as the Baltic Sea. Saildrone's partner sites in the Netherlands and Poland point to a broader European build-out of uncrewed surface capacity.
Saildrone's Explorer model can remain at sea for more than 12 months, while the Voyager and Surveyor models run about 100 days between servicing stops. The company reports these endurance figures, and the stub does not provide independent verification of them.
The players
Saildrone
Maker of wind-propelled autonomous surface vessels with radar, infrared, and AI surveillance systems, operating about 75 vessels on mission.
Umoe Mandal
Norwegian manufacturer that will build Saildrone's 65-foot Surveyor vessels.
Lockheed Martin
Defense contractor whose Joint Air-to-Ground Missiles were launched from a Saildrone Surveyor during RIMPAC 2026.
The details
Saildrone vessels use rigid, aircraft-like wings instead of fabric sails to harness wind for propulsion, which lets them move without fuel for long stretches. Each vessel carries radar, infrared cameras, satellite communication equipment, and artificial intelligence systems for surveillance. Umoe Mandal will manufacture the 65-foot Surveyor class in Norway, and the company's fleet spans four vessel classes from 23 feet to 170 feet.
Timeline
September 2023: The U.S. Navy deployed 10 Saildrone Voyagers in the Caribbean.
October: Sweden contracted four Voyagers for a yearlong maritime surveillance mission.
August 2026: Saildrone launched two Lockheed Martin Joint Air-to-Ground Missiles from a Surveyor during the U.S. Navy's Rim of the Pacific exercise.
The Tech Race
Saildrone's Surveyor and Voyager vessels now carry missile-launch testing during RIMPAC, moving the company's autonomous ships from pure surveillance into weapons-adjacent operations. Its European build-out in Norway, the Netherlands and Poland positions it against other uncrewed maritime suppliers serving NATO navies.
The Norwegian production line has no announced start date or capacity, so availability of additional Surveyor vessels to European buyers remains unscheduled. Current Voyager and Surveyor vessels are already in use by navies, while civilian access is not addressed in the source.
The takeaway
Watch whether Umoe Mandal's Norwegian line begins Surveyor output on a published schedule. Saildrone's next verifiable milestone is the delivery of those vessels to European navies under the Sweden and Denmark contracts.
