HII to Build Four ROMULUS 151 USVs at Breaux Brothers Facility
HII plans to build four production-ready ROMULUS 151 autonomous surface vessels at Breaux Brothers Enterprises in Louisiana, adding to the one unit already under construction. This expansion accelerates HII’s shift from prototype to serial production, leveraging its HYPR robotics initiative to deliver unmanned maritime capability more efficiently.
1. Production Expansion
HII has greenlit the construction of four additional ROMULUS 151 autonomous surface vessels at its Breaux Brothers Enterprises facility in Louisiana, supplementing the prototype already underway. This move marks the transition from single-unit demonstration to initial production, positioning HII to ramp output for U.S. Navy and allied needs.
2. Modular Design and Capability
The ROMULUS family features a modular, AI-enabled architecture that supports intelligence, surveillance, reconnaissance, mine countermeasures, strike operations, and unmanned vehicle launch and recovery. Standardized autonomy baseline and common manufacturing approach ensure each vessel meets diverse mission profiles while maintaining interoperability across fleet operations.
3. Scalable Manufacturing Ecosystem
Production leverages HII’s High-Yield Production Robotics (HYPR) initiative and existing unmanned vessel assembly lines to introduce industrial robotics, advanced tooling, and digital quality systems. These enhancements aim to reduce unit costs, improve schedule predictability, and enable high-rate, repeatable manufacturing of unmanned platforms.
4. Strategic Implications
Accelerating ROMULUS production reinforces HII’s leadership in autonomous maritime systems and strengthens its order pipeline for unmanned vessels. By moving quickly from prototype to serial builds, HII is poised to capture growing defense demand for scalable, next-generation naval capabilities.
