The verified answer

As of Sep 2026, DEPLOY verifies SM300 / SM200, a maritime surface by Sea Machines Robotics (commercial): 1 verified deployment on record. 3 sources back the record.

Overview

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.

Notes

Verified: Sea Machines Robotics (Boston; founder Michael Johnson) is an autonomy-SYSTEM vendor: it sells the autonomy brain (SM300/SM200), the customer owns/operates the boat. Late-2024 leadership: David 'Chip' Wasson (ex-Huntington Ingalls) became CEO, Johnson -> President/CTO - a defense-pull hire, NOT a distress signal (record 2024 sales + defense expansion). '200+ systems delivered worldwide'. $10M Series C (Mar 2025); ~$52M total raised., Model + maturity (distinct): Autonomy-system SALE (B2B technology vendor), distinct from Saildrone (operator) and the vessel makers. The registry should credit it with UNITS DELIVERED (200+), NOT sea-days (its autonomy runs on others' hulls). maturity=commercial (real shipping product, class approval, 200+ deliveries); pilot-to-commercial in defense. Strongest regulatory signal of the commercial set: explicitly class-society-approved hardware., AI-substance: genuine (system): Edge perception, COLREGS-style collision avoidance, path-following, remote command - substantive autonomy stack, not veneer. Honest caveat: it is autonomy software/hardware on someone else's hull, so 'operational scale at sea' is not directly Sea-Machines-attributable., Claimed but NOT verified: Specific class society (unnamed); named commercial customers; SM300-SP '100 units/month' actual throughput (stated capability); exact funding total; specific Navy program/contract value.

Specs

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.
