Sea Machines Robotics
Sea Machines Robotics is a Maritime Autonomy company founded in 2015 and based in Boston, United States.
Sea Machines Robotics was founded in 2015 in Boston by marine engineer Michael G. Johnson, who conceived the idea while working on an Arctic oil-spill response team. The company builds autonomous-control and remote-command systems that retrofit onto existing commercial and government vessels, letting onboard computers hold position, steer, manage speed and reroute around obstacles using streaming sensor data. Its product line spans the SM-series autonomy kits, the AI-ris 4K computer-vision system, and unmanned surface vessels aimed increasingly at defense and contested-waters missions. Sea Machines has raised multiple rounds, including a $15M financing in 2020 with participation from Huntington Ingalls Industries, and reports 200+ deliveries worldwide. In 2026 the company reported sales roughly 10x the prior year with bookings up 80%, its STEAMRACER vessel entered the final phase of the US Navy's MASC program, and in June 2026 Sea Machines was selected among seven companies for the Navy's MUSV family-of-systems effort.
Sea Machines is an early, widely-deployed maritime-autonomy retrofit player bridging commercial workboats and defense USVs.
