Executive Summary
HII announced the successful delivery and sea testing of two ROMULUS-25 unmanned surface vessels (USVs) under a Defense Innovation Unit (DIU) contract for the U.S. Marine Corps. This prototype contract validates HII's autonomous technology maturity and positions the company for potential larger-scale production awards, though no contract value or follow-on orders were disclosed.
Key Facts
- Two ROMULUS-25 USVs delivered in December 2025 and successfully tested for autonomous mission behaviors
- Contract awarded by Defense Innovation Unit (DIU) for smaller form factor autonomous boat prototypes for U.S. Marine Corps
- ROMULUS-25 is a 27-foot vessel with 1,000 lb payload capacity and 1,000 nautical mile range
- Powered by HII's Odyssey AI-based autonomy system, validated through 2,200+ hours of government-led tests and 12,000+ hours of at-sea operations across 30+ platforms
- Part of HII's broader USV family ranging from 7-foot micro-USVs to 190-foot ROMULUS-190
- Contract value not disclosed
Financial Impact
Undisclosed contract value; represents prototype phase with potential for larger production follow-ons
Risk Factors
- Contract value undisclosed and likely modest at prototype stage
- No guaranteed follow-on production orders
- Competition from other USV developers (e.g., L3Harris, Textron, Leidos)
- Budget uncertainty for USMC unmanned programs
