In the Middle East, uncrewed maritime systems are supporting continuous national surveillance operations in extreme heat, high salinity, congested waters and a complex security environment. Since August last year, these operations have been running around the clock in live conditions, generating more than 13,000 hours of operational experience.

For Joe Robinson, President of Solutions at Ocean Infinity, that experience has underscored a central point about maritime autonomy: the challenge is not proving that a system can work, but proving that it can keep working to do the job it was designed to do. In this case, that means persistence, 24/7/365.

The presence of autonomous and robotic systems is no longer novel. Governments and businesses around the world are already exploring how to use them. The key question now is what sustained operations reveal that one-off demonstrations cannot: whether these systems can produce effective operational outcomes consistently over long periods of time.

Why persistence is difficult

Operational failure is often not simply a technology problem. Persistent operations fail because operating robotic systems at sea, continuously and at scale, is extraordinarily difficult, Robinson said.

He described the maritime domain as one of the harshest operating environments on the planet. Ocean Infinity is currently operating in the Middle East, where temperatures regularly exceed 50 degrees. Combined with saltwater, humidity, corrosion, vibration and biofouling, those conditions place constant stress on platforms and sensors.

Robinson said the company’s vessels have sucked up fishing gear and cameras have melted in the heat. These are not edge cases, he said, but part of normal operations. Live use has exposed equipment limits that manufacturers have not previously had to solve, meaning new problems have had to be addressed in real time while service continuity is maintained.

Keeping systems operating in those conditions depends on an integrated delivery model that combines technology, people and process. Maintenance cycles do not always behave as expected. Fuel consumption changes with weather and mission profile. Sensors degrade incrementally. The company has also faced intermittent or deliberately disrupted communications, requiring systems that do not depend on constant connectivity. Decisions have to be made under pressure.

According to Robinson, predictability was not guaranteed at the start. It has been earned through experience, adaptation and a better understanding of how systems behave in the real world.

What sustained operations teach

Robinson said success in robotics is determined by what is learned in operation: how systems degrade, where redundancy is needed, how maintenance patterns evolve, where recovery takes longer than expected and how performance shifts under stress.

That is where sustained operations create a real advantage, he wrote, because they build understanding that cannot be replicated through showcases or trials. That learning becomes increasingly important as autonomy moves into mainstream maritime use, where reliability and continuity matter as much as capability.

He said much of Ocean Infinity’s learning came from years of deepwater multi-AUV deployments in extreme conditions, where repeatable performance is crucial. The company has worked in remote parts of the ocean from the Pacific to the Indian Ocean and Antarctica, carrying out complex offshore data collection in water depths of up to 6,000 metres.

From trials to dependable infrastructure

As navies, coast guards and maritime authorities consider hybrid fleets, persistent surveillance and the protection of critical infrastructure, Robinson said success will depend on whether uncrewed platforms can be relied on as part of continuous operations.

For these systems to contribute meaningfully, he said, they must behave less like experimental technology and more like dependable infrastructure: available when required, predictable in performance and resilient under disruption.

This is especially clear in live maritime security operations. When systems are expected to operate for extended periods without intervention, the question is not only whether they can perform a task, but whether they can keep doing it reliably as conditions change.

Robinson said that even during periods of regional instability, surveillance must be maintained, something Ocean Infinity has experienced firsthand. Operators remain onshore and out of harm’s way, but presence still has to be sustained. That requires more than capable platforms; it requires an operating model resilient enough to absorb disruption without losing continuity.

He also said this continuity depends on outstanding people. Sustained operational experience, he said, is what builds the understanding of how systems behave over time and how operations must adapt. There are no shortcuts to that knowledge, and it is one of the clearest distinctions between theory and real-world capability.

Evidence that supports regulation

Robinson also pointed to a regulatory dimension. The more hours these systems accumulate in live operations, the more the discussion can shift from what autonomy might do in theory to what it has demonstrably done in practice.

He said real operational evidence provides a stronger foundation for informed regulatory decision-making than hypothetical scenarios alone. The same experience also shapes how operating models are designed, from maintenance and recovery to data, decision-making and people in the loop.

That matters for an industry still moving from pilot projects toward wider operational acceptance, because regulators and operators alike need evidence that survives beyond controlled demonstrations.

That is how sustained operations become repeatable rather than heroic, and how autonomous systems begin to function as dependable infrastructure rather than experimental technology.

Proof is what keeps working

Robinson’s conclusion was direct: the sector does not need more claims about what autonomy might one day achieve in ideal conditions. It needs a clearer understanding of what sustained operations are already teaching now — that operational maturity is built through discipline, adaptation and continuity.

In maritime robotics, he wrote, proof is not a single successful mission. It is what can be kept running on day 10, day 100 and beyond.
