HII's ROMULUS unmanned surface vessel (USV) program has reached another major milestone thanks to the strong partnership with Breaux Brothers Enterprises in New Iberia, Louisiana. Together, the teams have completed the structural build of the first ROMULUS 151 USV hull and successfully flipped the vessel, an essential step that now opens the way for deck and pilothouse construction.

With a total of five ROMULUS 151 vessels currently under construction—four at Breaux Brothers and one at Halimar Shipyard of Morgan City, Louisiana—HII and partners are strengthening maritime readiness by delivering scalable, dependable autonomy built with shipyard discipline and real-world mission insight.

This milestone reflects the power of industry collaboration in accelerating the delivery of advanced autonomous maritime systems. Breaux Brothers’ craftsmanship and shipbuilding expertise, combined with HII’s autonomous technology leadership, are driving ROMULUS production forward at scale.

ROMULUS is a modular family of AI-enabled USVs built on HII’s open-architecture Odyssey Advanced Autonomy Solutions and designed to meet current and emerging requirements for the US Navy, US Marine Corps, joint forces, and allied partners. The platform supports a wide range of missions, including intelligence, surveillance and reconnaissance (ISR), mine countermeasures, strike operations, counter-unmanned systems, and the launch and recovery of unmanned underwater and aerial vehicles.
