US Navy picks Boston startup's crewless ship to map the deep ocean
Blue Water Autonomy wins a share of a $40 million Navy contract to survey the Indian and Pacific ocean floors using a 190-foot autonomous vessel that can sail for months without a human aboard.
Key points
- Blue Water Autonomy, founded in 2024, won a share of a $40 million US Navy contract to map deep ocean floors using crewless ships.
- The Liberty Class vessel is 190 feet long, carries over 150 metric tons of payload, and can travel more than 10,000 nautical miles on a single mission.
- Blue Water Autonomy raised $50 million in Series A funding in 2024, bringing its total to $64 million.
- Crewed survey ships can cost tens of thousands of dollars per day; autonomous vessels aim to cut that sharply.
- The company expects to deliver its first Liberty Class to the US Navy later this year.
A Boston startup less than two years old just landed a slice of serious Navy business. Blue Water Autonomy has been selected for a multi-year contract with the Naval Oceanographic Office, the branch of the US military that maps and measures the world's oceans. It's structured as an indefinite-quantity award: the Navy commits to a pool of money and orders work from the selected companies as it needs it, with a combined ceiling of $40 million across all winners.
The job is to send crewless ships hundreds to thousands of nautical miles offshore, mapping the ocean floor in high resolution and measuring the acoustic environment, meaning how sound travels underwater, which matters enormously for submarine navigation and detection.
What exactly is this ship?
The Liberty Class is a 190-foot steel ship with no crew. It can travel more than 10,000 nautical miles on a single mission and carry over 150 metric tons of sensors and equipment. New York to Tokyo is roughly that distance.
Blue Water Autonomy built the vessel on Damen's Stan Patrol 6009 hull design, then redesigned the interior entirely for autonomous operation. Use a hull that already works, focus engineering on the software and AI systems that let the ship make decisions at sea without anyone on the bridge. The first completed Liberty Class is due to the Navy this year.
Why does the Navy want crewless survey ships?
Cost and scale. A traditional crewed survey ship costs tens of thousands of dollars a day to run, mostly because of the sailors aboard. A vessel that needs no crew, no food, no rest can stay at sea for months and cover far more ocean for the same money, while keeping people out of harm's way on long, remote missions.
NAVOCEANO has been steadily shifting this kind of work to uncrewed systems, as first reported by The Robot Report. Deep ocean surveys are exactly the type of long, repetitive, high-endurance task where removing the crew makes financial sense.
We first covered Blue Water Autonomy on 4 August 2026, when the company featured in our roundup of July's biggest robotics stories.
| Spec | Liberty Class |

| Crew | Zero |
| First delivery | 2025 (planned) |
What does this mean for ordinary people?
Better ocean maps benefit everyone. Accurate seafloor data improves the safety of undersea cables that carry most of the world's internet traffic and informs climate research. CEO Rylan Hamilton, speaking to The Robot Report, put it plainly: "This selection puts our autonomy to work across the Indian and Pacific oceans, well beyond the range of a crewed survey ship." That reach is the point. One autonomous vessel can cover territory that would take several crewed ships, and the data it gathers shapes how safe and efficient global shipping and communications infrastructure can be.
Common questions
Is this ship fully self-driving or does a human control it remotely?
Blue Water Autonomy describes its vessels as fully autonomous, meaning onboard AI handles navigation and mission decisions. The company hasn't publicly confirmed whether a remote operator can intervene, which is a common safety backstop on autonomous ships.
How does $40 million split between multiple companies?
The $40 million is the total ceiling across all companies selected for this contract pool. Each company competes for individual task orders as the Navy issues them, so no single company is guaranteed the full amount.
