ROMULUS™
Family of Unmanned Surface Vessels
Modular. AI-Enabled. Mission-Ready.
Built by HII, America’s largest shipbuilder, and powered by Odyssey Advanced Autonomy Solutions®, ROMULUS™ is a high-endurance, 25+knot family of unmanned surface vessels (USVs) engineered for sustained open-ocean operations, rapid reconfiguration and cost-efficient production. Designed with the U.S. Navy, U.S. Marine Corps, joint forces, and allies in mind, ROMULUS™ brings proven autonomy to the surface fight.
ROMULUS™ brings proven autonomy to the surface fight. ROMULUS™ integrates with REMUS unmanned undersea vehicles (UUVs), HII’s Mission Management System and the Odyssey™ suite of autonomy solutions to provide a unified control framework that connects airborne, undersea, surface and crewed assets to coordinate data collection and effect delivery across domains.

Delivering the Collaborative Advantage with REMUS + Odyssey
HII's Mission Management System, Odyssey Advanced Autonomy Solutions®, REMUS UUVs, and ROMULUS USVs deliver coordinated surface-and subsurface operations with extended detection ranges and safer standoff positioning for manned assets.
With ROMULUS, HII reinforces its position as the global leader in durable, mission-ready autonomous unmanned systems. Developed with support from HII’s Dark Sea Labs Advanced Technology Group, ROMULUS takes its place alongside the proven REMUS UUV line with more than 700 delivered to over 30 nations—and over 90% still operational after more than two decades. Together, ROMULUS and REMUS, powered by HII’s Odyssey autonomy, form a dual-domain family of unmanned platforms that expands operational reach, maximizes mission flexibility, and ensures dependable performance across the full maritime spectrum.
Pair HII’s unmanned surface vessels with its unmanned underwater vehicles to extend reach and reduce risk:
- Anti-Submarine Warfare (ASW): Integrate REMUS UUV-launched ASW capability for improved undersea area coverage to reduce risk to mission and force.
- Mine Countermeasures (MCM): Decades of REMUS mine-hunting expertise to accelerate clearance and reduce risk to fleet operations.
Partnerships Driving Innovation
Built with leading industry partners Breaux Brothers, Halimar Shipyard, Beier Integrated Systems, Bayou Metal Supply & Manufacturing, and Incat Crowther, ROMULUS™ features a commercial-standard hull optimized for rapid, repeatable production, and mission-ready deployment. Through collaboration with Applied Intuition, ROMULUS™ expands its autonomy, object classification, and lifecycle sustainment capabilities. Odyssey’s open-standard, government-aligned architecture allows rapid integration of new sensors, payloads, and third-party autonomy technology.
This open-access approach enables industry, government, and academia to test and refine capabilities, ensuring ROMULUS™ evolves in step with emerging naval concepts of operations. All of which align ROMULUS™ with the goals of major emerging programs, including the U.S. Navy’s Medium Unmanned Surface Vessel (MUSV), the U.S. Marine Corps’ Long Range Unmanned Surface Vessel (LRUSV), and next-generation naval unmanned programs.
