Editorial summaries
Ghost Shark (XL-AUV)
Anduril's Ghost Shark is an extra-large autonomous undersea vehicle (XL-AUV) and the production-maturity anchor of the defense-subsea cohort, extending the new-defense AI-first model (Anduril, Shield AI, Helsing, and Saronic on the surface) into the subsea regime. It is co-developed with the Royal Australian Navy and the Defence Science and Technology Group, leverages Dive-LD technology and Anduril's Lattice AI, and is backed by an A$1.7 billion RAN production contract (September 2025). Two cap-flags: the A$1.7B figure is the production contract, distinct from the A$140M 2022 co-development funding that aggregator reporting sometimes conflates with it; and detailed specs (around 12 meters length, plus displacement, endurance, and depth) are estimates, because the Australian Department of Defence withholds the design. It is defense procurement; there is no consumer price.
SM300 / SM200
Sea Machines Robotics (Boston; founded by Michael Johnson) is the autonomy-system-vendor archetype of the maritime category: it makes the autonomy brain, not the boat. 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 hull while Sea Machines licenses the autonomy onto it. 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 change brought David Wasson (formerly of Huntington Ingalls) in as CEO with founder Johnson moving to president and CTO, a defense-pull hire on a $10M Series C (March 2025) and about $52M total raised. DEPLOY records it at commercial maturity on 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. The SM300-SP claim of more than 100 units a month is a stated production rate. As a B2B autonomy licensing business, no consumer price is published.
