They Own the Fleet. You Buy the Hours.

Week 46 | October 2026

On 22 September, four ten-metre sailing drones became the first Saildrone vessels registered under a national flag. The flag is Danish. The hulls still belong to Saildrone, and the remote operators who run them from shore are on its payroll.

That arrangement is this week’s story.

In Week 40 (Own the Factory or Own the Sonar) I set out Saronic’s bet (build the whole vessel in its own yard) and Kraken Robotics’ (sell the sensors and batteries that go inside everyone else’s). A third route has been quietly winning contracts all year: own the fleet, operate it yourself, and sell what it sees.

Saildrone is the clearest case. For its Caribbean counter-drug mission, the US Navy buys time on station. A US$16.3 million task order, awarded on 30 June and announced in August, keeps around 20 Voyagers working for 4th Fleet and Joint Interagency Task Force South into 2027. Saildrone has run that mission since 2023. The US Coast Guard signed a US$15.5 million contract with Saildrone in March to deploy and run 16 Voyagers: six on the Great Lakes and ten off the Northeast on illegal-fishing patrols.

Denmark came first in Europe. Saildrone’s Voyagers went into the Baltic in June 2025 under contract to the Danish Armed Forces, and four of them ran for six months. The company reports 92% fleet uptime and more than 170,000 logged contacts (its own figures, so read them as such). Its Copenhagen headquarters opened in August and is hiring remote operators and vehicle technicians, alongside mission management. That hiring list tells you what Saildrone thinks it sells.

The commercial version looks much the same. XOCEAN, out of Ireland, raised €115 million in January 2025, when its chief executive put the fleet at 30 USVs, and it sells survey data to wind developers. Eneco signed a five-year deal with it covering six Dutch wind farms. Lloyd’s Register certified its X-30 to the UK Workboat Code Edition 3 in March, and the next-generation hull is moving into series production. Ocean Infinity does it at a bigger scale again, with a fourteen-ship Armada of lean-crewed vessels run from control rooms ashore.

Here’s why buyers like it. A service contract buys an output: contacts logged, or square kilometres mapped. Everything that usually stalls an autonomy program becomes the vendor’s problem. Shipyard slots. Crew training. Certification. Maintenance. Liability when something goes wrong.

The UK is running the biggest test. Atlantic Net, the first phase of the Royal Navy’s North Atlantic anti-submarine effort, was tendered in October 2025 as underwater ISR delivered as a service. The contractor owns and operates the kit under naval oversight, and the data goes straight to the operational commander ashore. Twenty-six compliant proposals came in, and five consortia made the shortlist. Janes, citing industry sources, reports that an Ocean Infinity-led team is in final negotiations. In August the UK First Sea Lord promised the first sensors in the water by the end of the year. Set that timeline against any crewed anti-submarine program of record and the appeal is obvious.

The fast lane slips too. Janes had the MoD choosing its partner by the end of May. It’s late October and no contract has been announced.

There’s a money angle as well (my reading, not the MoD’s). Services usually come out of operating budgets, renewed year to year. That keeps them clear of procurement scrutiny and exposed to every budget round that follows.

Speed has a price, and most of it sits in the fine print.

First, availability when it counts. A contractor’s fleet answers to the contractor. On a peacetime grey-zone patrol, that rarely matters. In a shooting war it matters a great deal. That makes Denmark’s flag registration more interesting than it looks. Denmark is now Saildrone’s flag state as well as its customer, and the state fund EIFO led the company’s US$60 million round in 2025. 

Danish defence law already lets the defence minister, in war or other extraordinary circumstances, control the sailing of Danish ships and require property to be made available for national defence (with full compensation), so the flag gives Copenhagen a lever over the hulls.

Second, the people. Atlantic Net is designed to split the work: contractors run the hardware and naval personnel at a remote operations centre do the analysis. The general law here exists, and it isn’t comforting. An ICRC expert paper treats operating an unarmed sensor that is integral to ongoing hostilities, such as a drone locating fleeting targets, as potential direct participation in hostilities. What I couldn’t find is anyone applying that to a contractor-run anti-submarine network like Atlantic Net. If no one has, someone needs to write it before the first real contact.

Data is the third, and buyers have already drawn a line. Saildrone says the Coast Guard’s data belongs to the customer. That matters for anyone hoping to build a fourth model on top of this one, selling the same seabed or contact data to many buyers. Bedrock was the company most associated with that idea, and its 2026 has gone on defence partnerships and a partner-operated hub in Aberdeen. For now, the data library is an option on commercial seabed data and little more.

Then lock-in. When the Royal Navy direct-awarded Teledyne a glider and float contract this year, the justification was that only Teledyne could guarantee interoperability with the Navy’s existing glider fleet. The Navy owns those gliders. Incumbency hardens fast, whoever owns the hulls.

Read the buyers’ own plans and the service model looks like an on-ramp. Atlantic Net is the first strand of the Royal Navy’s wider Atlantic Bastion program. The original Project CABOT plan moved the capability into government ownership in a second phase, built around new Type 92 and Type 93 uncrewed platforms (Type 92 has since been recast as an underwater sensing platform). The Royal Navy bought 20 Kraken Technology Group K3 Scouts (no relation to Kraken Robotics) outright under Project Beehive in March. Australia ordered 40 more Bluebottles for A$176 million the same month, taking the RAN’s fleet to 55, though the Navy owns the boats and Ocius operates them. Saildrone is developing the 52-metre Spectre with Lockheed Martin and Fincantieri. Its head of European business development says that one will carry kinetic effectors. Strike platforms get sold.

So here’s where I land. Services are the fastest way to put allied sensors in the water right now, and for peacetime surveillance and commercial survey they’ll stay that way. The hard part comes when a navy decides a mission is core and wants the assets and operators in-house. At that point it inherits the vendor’s data formats and the vendor’s trained people. The institutional gap reappears right there, at the handover. It’s cheapest to close on day one, with data ownership and a handover plan written into the contract before the first drone sails.

Since you have been, thanks for reading.

Cheers,

Mick
