The US Navy could soon get a boost at sea as Sea Machines unveiled its next-gen unmanned surface vessel (USV) aimed for the service’s Modular Attack Surface Combatant (MASC) program.
Known as STEAMRACER, the AI-enabled vessel features a modular open-deck payload, an advanced command system, and an onboard network suite designed to support distributed operations at scale.
Engineered for unmanned missions, the USV can switch to manned mode if needed, without compromising its autonomous-first design.
Sierra Nevada Corporation supplies advanced transmission tech that strengthens onboard communications, cybersecurity, and networked operations across the fleet.
The vessel is being built in collaboration with US industrial partners, including St. Johns Ship Building, TOTE Services, Ring Power, Incat Crowther, and EMI-W&O.
Approaching the Fleet
STEAMRACER has officially entered the US Navy’s final assessment phase for the MASC initiative.
It is expected to support efforts to expand medium USV production, scale autonomous capabilities, and deploy maritime systems rapidly.
Sea Machines highlighted that the current strategic environment demands operational mass, speed, and scale, not extended development or another prototype.
“We deliver proven autonomy at the pace required for deterrence in the Indo-Pacific, or wherever in the world it will be needed,” the company stated.
