Robot model
SM300 / SM200
Sea Machines Robotics (Boston; founded by Michael Johnson) is an autonomy-system vendor for surface vessels rather than a vessel maker: its SM300 and SM200 autonomous-command systems are vessel-agnostic retrofit kits, about ten components installed in two days or less on existing or new-build workboats from 10 to 300 feet, so the customer owns and operates the boat while Sea Machines supplies the autonomy brain. The September 2025 SM300-NG adds class-society-approved hardware, a 200-percent compute increase, full voyage control with collision avoidance and sensor fusion, and worldwide remote command, alongside an attritable SM300-SP defense variant. A late-2024 leadership transition saw David Wasson, formerly of Huntington Ingalls, become CEO with founder Johnson moving to president and chief technology officer, a defense-pull hire rather than a distress signal given record 2024 sales and a defense expansion, on a $10 million Series C in March 2025 and about $52 million total raised. The registry records it at commercial maturity on the strength of a real shipping product, class-society approval, and more than 200 systems delivered worldwide, and it credits the company with units delivered rather than sea-days, since its autonomy runs on other companies' hulls and operational scale at sea is not directly attributable to it. Its autonomy is genuine, with edge perception, collision avoidance, path-following, and remote command, and it holds the strongest regulatory signal of the commercial set in its class-society-approved hardware, while the specific class society, named commercial customers, the SM300-SP hundred-units-per-month throughput, and specific defense contract values are not verified.

- SM300 / SM200 autonomous-command systems: vessel-agnostic autonomy retrofit kits installed on existing/new-build workboats (10-300 ft), ~10 components, install in <=2 days. SM300-NG (Sept 2025): class-society-approved hardware, +200% compute, full voyage control, COLREGS-style collision avoidance, ENC/radar/AIS/video fusion, worldwide remote command. SM300-SP: attritable/volume-production defense variant (claimed >100 units/month). Founded by Michael Johnson; Boston.

Supply chain
No verified supply relationships on file. Supply-chain coverage is being added across the registry; check back as the seed populates this model’s suppliers.
Suppliers appear here when verified with at least two strong sources (maker-official / IR / regulatory / standards-body / verified tier-2). Sources are append-only; corrections add new sources rather than rewrite history.

- Who makes SM300 / SM200?
- SM300 / SM200 is made by Sea Machines Robotics, based in Boston, Massachusetts, USA, founded in 2018.
- Where is SM300 / SM200 deployed?
- No verified deployments of SM300 / SM200 are currently on the DEPLOY registry. DEPLOY records deployments only when verified at a named site with a primary source; absence may reflect pre-deployment, research, or manufacturer-internal use.
- What is SM300 / SM200's maturity stage?
- SM300 / SM200 is at the commercial stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Commercial stage means production-grade deployments are operating at named customer sites.
