Off the coast of the Netherlands, crewless vessels circle a target ship in silence — no lives at risk, no human hand on the helm. The Royal Netherlands Navy is not merely testing new equipment; it is rehearsing a new philosophy of war, one in which machines extend human reach while humans retain the weight of moral decision. This shift, mirrored by militaries across the globe, raises questions that technology can accelerate but never resolve: who is responsible when an autonomous system errs, and where does accountability live when the hand that acts belongs to no one?
Dutch Navy Leads Global Shift to Unmanned Sea Defences
A person is always part of the decision-making chain
Mark
Why does a small country like the Netherlands lead on this? Why not the Americans or the British?
Mimi
Size is actually an advantage here. The Dutch have a labour shortage and they operate in a strategically dense region. They can't afford to station large crews for months at a time. Unmanned systems let them do more with fewer people.
Mark
But doesn't automation usually mean fewer jobs overall?
Mimi
Not in this case. You need more engineers, more software specialists, more people managing the systems remotely. The work changes, but it doesn't disappear. And the people who do it get to go home at night.
Mark
What about the ethical problem—who is responsible if an autonomous system makes a mistake?
Mimi
That's the question nobody has fully answered yet. The Dutch have been wrestling with it for 40 years with their Goalkeeper system. They're saying a human always stays in the decision loop, but as systems get smarter, that line gets blurrier.
Mark
Can the AI actually fail in dangerous ways?
Mimi
Yes. It can misidentify targets. It can generate false readings. One of their engineers said it plainly: you have to let the system work for you, but not think for you. That's the balance they're trying to find.
Mark
Is this happening everywhere now?
Mimi
It's accelerating. Ukraine showed what drones can do. The US Navy is already using unmanned vessels. The UK is spending billions. The Dutch are just ahead of the curve, showing what's technically possible. Everyone else is watching.
The Pulse
- Two crewless vessels already patrol Dutch waters autonomously, marking a live transition — not a future ambition — toward machine-led naval operations.
- The Netherlands has committed to unmanned systems handling more than half of all naval operations within five years, a timeline that compresses decades of military doctrine into a single strategic leap.
- AI systems capable of 'hallucinating' threats introduce a new category of danger: not enemy fire, but algorithmic error with potentially lethal consequences.
- Engineers are replacing sailors in the workforce calculus, reshaping what a naval career looks like — less time at sea, more time debugging the machines that go instead.
- The question of culpability in automated warfare remains unanswered, even as the Dutch, the British, and the Americans accelerate deployment without a settled ethical framework.
Off the coast of the Netherlands, crewless vessels circle a target ship in silence — no lives at risk, no human hand on the helm. The Royal Netherlands Navy is not merely testing new equipment; it is rehearsing a new philosophy of war, one in which machines extend human reach while humans retain the weight of moral decision. This shift, mirrored by militaries across the globe, raises questions that technology can accelerate but never resolve: who is responsible when an autonomous system errs, and where does accountability live when the hand that acts belongs to no one?
Off the northern Dutch coast, two black vessels move in silent formation around a target ship. Defender 1 and Defender 2 carry no crew. They watch, record, and report — and no one is in harm's way. This is not a demonstration. It is a rehearsal for the navy's next decade.
Captain Sjoerd Feenstra oversees the trial near Den Helder, pushing autonomous platforms toward their limits over five weeks. His vision is a crewed ship at the centre, encircled by a protective ring of uncrewed vessels and drones operating as independently as possible. The Netherlands has committed to unmanned systems handling more than half of naval operations within five years. The UK is investing over £5 billion in parallel. Lessons from Ukraine, the Middle East, and the Persian Gulf — where the US Navy deployed unmanned vessels against Iranian forces — are driving the momentum.
The testing platform is the GeoSea, a former seabed survey vessel now serving as a floating laboratory. Noa drones launch from its deck. Defender boats cut through the water. A Lobster Robotics vehicle maps the depths for mines. The system is modular by design: new technology can be swapped in as it matures, without dismantling what already works.
Software integration lead Ferdinand Peters is candid about the risks. AI can malfunction, produce false readings, or hallucinate threats that do not exist. 'You need to let the system work for you, but not think for you,' he says. The line is firm: no machine will decide to fire a weapon. Humans remain in the chain. Always.
The ethical questions are not new — the Netherlands has operated the fully autonomous Goalkeeper air defence system for over 40 years — but they deepen as automation expands. Feenstra acknowledges the unresolved core: even human-made plans go wrong. When a machine executes the plan, where does culpability rest? There is no clean answer.
Naval analyst Lee Willett notes that the Dutch, a small navy in one of the world's most strategically critical waters, punch well above their weight. By pioneering this shift, they are charting a course others will follow. The change does not eliminate the need for people — it transforms what people do. More engineers, fewer long deployments, less repetitive danger. The direction, as researcher Sidharth Kaushal puts it, is no longer in question. Only the pace, and the rules that will govern the journey.
Off the northern coast of the Netherlands, two black vessels move in silent coordination around a target ship. Defender 1 and Defender 2 have no crew. A computer system steers them. They are watching, recording, reporting—and nobody is in danger of being hurt.
This is the working prototype of what the Royal Netherlands Navy will look like in a decade. Captain Sjoerd Feenstra, who runs the navy's centre for unmanned systems, is overseeing a five-week trial near Den Helder to push these autonomous platforms to their limits. The vision is straightforward: crewed ships at the centre, surrounded by a protective ring of uncrewed vessels and drones operating as independently as possible. "For the last year and a half we've been working to change our organisation," Feenstra says. "In about 10 years there will be crewed platforms surrounded by a ring of uncrewed systems operating as autonomously as possible."
The Dutch are not alone in this shift. Underwater drones, surface vessels, and aerial platforms without human operators are becoming standard equipment for militaries worldwide. The Netherlands has committed to using unmanned systems for more than half of its naval operations within five years. The UK is investing over £5 billion in similar technology over the same timeframe. The momentum is real, driven by lessons learned in Ukraine, the Middle East, and recent operations in the Persian Gulf, where the US Navy deployed unmanned vessels against Iranian forces.
The testing ground is the GeoSea, a vessel originally built to survey seabeds around offshore wind farms. Now it serves as a floating laboratory. Noa drones—mechanical insects the size of small aircraft—launch from its deck. The Defender boats cut through the water. A Lobster Robotics undersea mine mapper works the depths. The system is designed to be modular: as technology improves, new equipment can be swapped in without rebuilding the entire operation.
But autonomy comes with hard questions. Ferdinand Peters, the software integration lead, is blunt about the risks. Artificial intelligence can malfunction. It can generate false results. It can "hallucinate," seeing threats that aren't there. "You need to let the system work for you, but not think for you," Peters says. "We need to think carefully about where we use it and where we do not." No machine will make the decision to fire a weapon. Humans remain in the decision-making chain. Always.
The ethical terrain is not new. The Netherlands has operated the Goalkeeper air defence system—capable of functioning entirely on its own—for more than 40 years. Feenstra acknowledges the deeper problem: "What we know from the past is that even when people make the plan or collect the information, something can go wrong. The question is where the culpability will lie if you automate everything." It is a question without a clean answer.
Why does this matter beyond the Netherlands? Lee Willett, a naval analyst, notes that the Dutch punch above their weight in global security. They are a small navy operating in one of the world's most strategically critical regions—the North and Baltic seas. By pioneering unmanned systems, they are showing other nations what is possible. Sidharth Kaushal, a sea power researcher at the Royal United Services Institute in London, sees the shift as inevitable. Unmanned systems do not eliminate the need for personnel; they change what personnel do. More engineers are required. But sailors spend less time away from home. The work becomes less repetitive, less dangerous. "This is the direction of travel," Kaushal says. The question is no longer whether navies will adopt these systems, but how quickly, and what rules will govern them.
