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 company's Liberty Class vessel is 190 feet long, carries over 150 metric tons of cargo, and has a range of more than 10,000 nautical miles.
- Blue Water Autonomy raised $50 million in Series A funding in 2024, bringing its total funding to $64 million.
- Crewed survey ships can cost tens of thousands of dollars per day to operate; autonomous vessels aim to cut that cost sharply.
- The company expects to deliver its first Liberty Class ship 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. The contract is structured as an indefinite-quantity award, meaning the Navy commits to a pool of money and then orders work from the selected companies as it needs it, with a combined ceiling of $40 million across all winners.
Blue Water Autonomy's job is to send its crewless ships hundreds to thousands of nautical miles offshore to map the ocean floor in high resolution and measure the acoustic environment, basically 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. For scale, 10,000 nautical miles is roughly the distance from New York to Tokyo.
Blue Water Autonomy built the vessel on a proven patrol-ship hull design from Dutch shipbuilder Damen, then redesigned the interior entirely for autonomous operation. The idea: use a hull that already works, and focus all the engineering effort on the software, sensors, and AI systems that let the ship make decisions at sea without a human on the bridge.
The company says it expects to hand over the first completed Liberty Class to the Navy this year.
Why does the Navy want crewless survey ships?
The short answer is cost and scale. A traditional crewed survey ship costs tens of thousands of dollars a day to run, partly because of fuel, but 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. It also keeps people out of harm's way on long, remote missions far from any port.
The Naval Oceanographic Office 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 human crew makes financial and practical sense.

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, informs climate research, and supports fishing and shipping industries. The Navy's investment in autonomous survey ships is funding technology that will eventually have civilian uses too.
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 has not 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.
