Press Release, National Harbor MD, 21 April 2026: HII, America’s largest military shipbuilder and global leader in autonomous maritime systems, announced today plans for the production of four ROMULUS 151 vessels to be built by Breaux Brothers Enterprises in Louisiana in addition to the ROMULUS 151 currently under construction. The announcement signals a rapid shift toward initial production, as HII pushes to accelerate delivery of autonomous surface capability to the US Navy and allied partners.
“ROMULUS represents a shift in how we deliver unmanned capability to the fleet,” said Andy Green, executive vice president of HII and president of HII’s Mission Technologies division. “We are combining shipbuilding experience, scalable manufacturing, proven autonomy, and strong industry partnerships to move quickly from prototype to operational deployment. The progress we are seeing today – including these initial production vessels – reinforces that we are on a disciplined path to deliver meaningful capability at speed and at scale.”
Built for Scale and Mission Flexibility: ROMULUS is a modular family of AI-enabled USVs 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.
Engineered for serial, repeatable production, ROMULUS vessels combine endurance, global reach, and modular adaptability. The family is designed to scale across multiple vessel sizes while maintaining a common manufacturing approach and autonomy baseline.
