ROMULUS^™

ROMULUS combines 25+ knot performance, long-endurance operations, and a commercial-standard hull engineered for rapid, repeatable production. Its reconfigurable design makes it a force multiplier for the U.S. Navy, Marine Corps, and allied fleets.

Mission-Ready Capabilities

• ISR & Targeting: Persistent intelligence, surveillance and reconnaissance with real-time data fusion and analytics for improved track identification.
• Counter-UAS & Force Protection: Detect, track and engage airborne threats with scalable effectors.
• Strike & Fires: Integrate current and future weapons and mission systems.
• Multi-Domain Operations: Launch and recover UUVs (such as HII's REMUS^™), UAVs and smaller ROMULUS^™ USVs

HII’s Mission Management System, Odyssey Advanced Autonomy Solutions®, and REMUS UUVs and ROMULUS USVs deliver coordinated surface‑and‑subsurface operations with extended detection ranges and safer standoff positioning for manned assets. Odyssey’s EMCON‑driven behaviors reduce exposure to counter‑detection, while its fully autonomous, COLREGs‑compliant navigation uses fused RADAR, EO/IR and AIS sensing to operate safely without operator input.

With millions of hours of operation, the architecture is operationally proven and production‑ready.

Features

• Commercial-Standard Construction: Built for rapid, repeatable production at scale with a durable, maintainable hull form.
• AI-Driven Autonomy: Powered by Odyssey’s open, government-aligned architecture for autonomous and collaborative operations.
• Modular and Reconfigurable Design: Enables rapid payload integration, fast mission changes and future technology upgrades.
• Open Access Innovation: Odyssey’s Modular Open Systems Approach (MOSA) architecture allows rapid integration of new sensors, payloads and third-party autonomy technologies.
• Odyssey Common Control Interface: Provides a unified framework for autonomy management and mission coordination.
• Multi-Domain Compatibility: Integrates seamlessly with larger system-of-systems networks across air, surface and undersea domains.
• Aligned with Key Naval Initiatives: Supports programs such as the U.S. Navy’s Modular Attack Surface Craft (MASC), the U.S. Marine Corps Long Range Unmanned Surface Vessel (LRUSV) and other next-generation naval unmanned efforts.

Built with leading industry partners Breaux Brothers, Beier Integrated Systems, and Incat Crowther, ROMULUS features a commercial-standard hull optimized for rapid, repeatable production, and mission-ready deployment.

Through collaborations with Shield AI, Applied Intuition, and C3 AI, 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 Modular Attack Surface Craft (MASC), the U.S. Marine Corps’ Long Range Unmanned Surface Vessel (LRUSV), and next-generation naval unmanned programs.

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.
