Newport News also works on aircraft carrier John F. Kennedy (CVN 79), which HII describes as being on track to become a highly capable carrier upon delivery to the Navy.

Mission Technologies and all-domain solutions

HII’s Mission Technologies division extends the company’s reach beyond traditional shipbuilding into advanced defense technologies. The division supports U.S. and allied customers with capabilities in unmanned systems, cyber operations, ISR, AI/ML, synthetic training, and C5ISR-related activities. Mission Technologies has been awarded work under the Missile Defense Agency’s Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract vehicle, opening opportunities in directed energy, command and control system integration, data and cyber operations, microelectronics, spectrum management, live/virtual/constructive training environments, logistics and sustainment.

Mission Technologies also develops and fields autonomous platforms and autonomy software. The company describes itself as the world’s leading manufacturer of autonomous underwater unmanned vehicles through its REMUS family of unmanned underwater vehicles (UUVs), and a leading manufacturer of autonomous surface and underwater unmanned vehicles more broadly. These systems support missions for U.S. and allied navies, defense customers, commercial operators and research organizations.

REMUS unmanned underwater vehicles

HII’s REMUS UUV family is one of the most widely deployed autonomous underwater vehicle lines in the world, with systems used by more than 30 navies, including 14 NATO members. REMUS vehicles are used for missions such as mine countermeasures, undersea survey, intelligence collection, environmental sensing, seabed mapping, reconnaissance and underwater survey. The REMUS line includes multiple variants designed for different operating depths and mission sets, with numbering that reflects operational depth and generation.

REMUS vehicles feature a modular, open-architecture design that supports rapid integration of new payloads, mission-specific configurations and future upgrades. This design approach is intended to help operators keep pace with evolving challenges and requirements while managing lifecycle costs. HII reports that more than 90% of REMUS units delivered over more than two decades remain in service, underscoring durability and long-term value. REMUS systems have been employed in defense, search and recovery, and scientific and environmental missions, including high-profile search, post-disaster response and oceanographic research applications.

ROMULUS unmanned surface vessels and autonomy

Complementing REMUS, HII is developing the ROMULUS family of unmanned surface vessels (USVs). ROMULUS platforms are described as modular, AI-enabled USVs powered by HII’s Odyssey Autonomous Control System (ACS). They are designed for high-endurance, open-ocean autonomy, with an emphasis on lethality, cost efficiency and scalability. ROMULUS USVs support missions including ISR, counter-unmanned air systems, mine countermeasures, strike operations, and launch and recovery of UUVs and unmanned aerial vehicles (UAVs).

ROMULUS is built around the Odyssey ACS, an autonomy suite used across dozens of USV platforms and hundreds of REMUS UUVs in numerous countries. Odyssey enables sustained open-ocean autonomy, multi-agent swarming, modular payload integration and manned-unmanned teaming. The ROMULUS program incorporates capabilities from partners such as Shield AI, Applied Intuition and C3 AI to enhance autonomous performance and lifecycle sustainment. HII is advancing ROMULUS through prototype construction and testing, with sea trials scheduled according to program milestones.

Global footprint and partnerships

HII’s operations extend beyond its U.S. shipyards. The company has expanded its unmanned operations in Europe with an enlarged facility in Portchester, United Kingdom, which serves as a regional hub for Mission Technologies. This facility supports the U.K. Royal Navy and European partners that operate REMUS UUVs, and provides operational, technical and logistics support for electronic warfare and C5ISR systems, fleet modernization, artificial intelligence capabilities and live, virtual and constructive training. It also prepares the region for deployment and sustainment of the ROMULUS USV family.

HII participates in international defense partnerships such as the AUKUS framework among Australia, the United Kingdom and the United States. Through its Newport News Shipbuilding division and Mission Technologies Global Security team, HII supports efforts to develop Australia’s conventionally armed, nuclear-powered submarine capability and related advanced technologies. The company is a founding member of the AUKUS Workforce Alliance and was awarded work under the Australian Submarine Supplier Qualification pilot program, aimed at integrating Australian suppliers into the U.S. submarine industrial base.
