6 terms

unmanned underwater vehicles (uuvs) technical

"including the REMUS family of unmanned underwater vehicles (UUVs) and the ROMULUS"

Unmanned underwater vehicles (UUVs) are robotic submarines that operate without an onboard crew, performing tasks like mapping the seafloor, inspecting pipes, collecting scientific data, or carrying sensors and equipment. Think of them as underwater drones — they matter to investors because they create revenue and cost-saving opportunities across defense, offshore energy, research and infrastructure inspection, while also carrying technology, regulatory and procurement risks that can affect company earnings and contracts.

unmanned surface vessels (usvs) technical

"ROMULUS family of AI-enabled unmanned surface vessels (USVs) as well as HII’s"

Autonomous or remotely controlled boats that operate on the water without onboard crew, like self-driving cars for seas and rivers. Investors pay attention because USVs can cut labor and operating costs, open new markets in shipping, coastal surveillance, and data collection, and carry technology and regulatory risks that can sharply affect manufacturers, service providers, and users' future revenues and valuations.

live, virtual, constructive (lvc) technical

"largest live, virtual, constructive (LVC) enterprise preparing warfighters for"

Live, virtual, constructive (LVC) describes a combined training and testing environment that links real-world equipment and people (live), simulated systems operated by humans (virtual), and computer-generated entities or scenarios (constructive) so they interact as if in one exercise. For investors, LVC capability signals a company can run realistic, scalable and lower-cost trials or demonstrations—think of a driving test that mixes an actual car, a human-driven simulator, and automated traffic—to reduce risk, prove performance and open recurring-service revenue.

odyssey autonomous control system (acs) technical

"HII’s Odyssey Autonomous Control System (ACS) software suite."

An odyssey autonomous control system (ACS) is an integrated set of sensors, software and hardware that lets a vehicle or machine navigate, make driving decisions and respond to its surroundings without a human at the wheel. Think of it as the vehicle’s pilot, co‑pilot and traffic controller bundled together; for investors it matters because performance, safety and regulatory approval of such a system can drive adoption, revenue potential, liability exposure and competitive positioning in transportation and robotics markets.

intelligence, surveillance, and reconnaissance (isr) technical

"teaming for intelligence, surveillance, and reconnaissance (ISR) missions."

Intelligence, surveillance, and reconnaissance (ISR) is the suite of tools and activities used to collect, analyze, and share information about people, places, or objects—using sensors such as satellites, aircraft, drones, cameras, or electronic signals—to give decision-makers a clear picture of what is happening. Investors care because ISR drives defense and security spending, supports recurring contracts for hardware, software, and data services, and can signal shifts in technology demand and geopolitical risk much like a bank account reveals financial health.

torpedo tube launch and recovery (ttlr) technical

"deliver a submarine Torpedo Tube Launch and Recovery (TTLR) system designed"

Torpedo tube launch and recovery (TTLR) is a hardware and procedure set that uses a submarine’s torpedo tubes to send out and bring back small devices such as underwater drones, sensors or munitions without the vessel surfacing. For investors, TTLR signals a capability that can lower operational risk, shorten deployment time and expand the market for naval systems and services—similar to a built-in garage that lets equipment go out and return discreetly and efficiently.

“HII is proud to be a partner to the U.S. Navy, Royal Navy, NATO allies, and international partners in supporting the growing need for autonomous capabilities and mission enabling technologies in naval operations across both the undersea and surface domains,” said Duane Fotheringham, president of the Unmanned Systems group in HII’s Mission Technologies division. “Our autonomous maritime systems are operating today in some of the world’s most demanding environments, and we continue to advance capabilities that extend mission reach, improve fleet survivability, and strengthen allied interoperability across the maritime domain.”

HII’s exhibit and presentations feature the company’s expanding portfolio of autonomous maritime technologies, including the REMUS family of unmanned underwater vehicles (UUVs) and the ROMULUS family of AI-enabled unmanned surface vessels (USVs) as well as HII’s Odyssey Autonomous Control System (ACS) software suite.

This year marks the 25th anniversary of the REMUS UUV family, widely recognized as the world’s leading autonomous underwater vehicle platform supporting defense, commercial, and scientific missions worldwide. HII has delivered more than 750 REMUS vehicles to over 30 countries, including 14 NATO members, with more than 90% of systems remaining operational after more than two decades of service.

HII’s Odyssey ACS software suite has demonstrated successful performance in U.S. Navy, U.S. Marine Corps, U.S. Coast Guard, and international allied programs. Odyssey’s intuitive interface and enhanced, customizable features generate the required mission behaviors for greater lethality and survivability with simplified control of unmanned swarms across domains, making it a force multiplier for the modern fleet.

HII is also highlighting several recent milestones demonstrating the rapid advancement of autonomous naval capabilities, including:

• A recent U.S. Defense Innovation Unit (DIU) contract award to deliver a submarine Torpedo Tube Launch and Recovery (TTLR) system designed to autonomously deploy and recover HII’s REMUS UUVs from U.S. Navy submarines.
• Successful forward-deployed torpedo tube launch and recovery operations of an HII-built REMUS 600 UUV from USS Delaware (SSN 791), marking a significant advancement in autonomous manned-unmanned teaming for intelligence, surveillance, and reconnaissance (ISR) missions.
• Expansion of HII’s unmanned systems presence in Europe through the recently enlarged Portchester, U.K., facility, which serves as a regional hub supporting allied naval customers, sustainment operations, training, and future deployment of autonomous systems.
• Continued progress toward scaled production of HII’s ROMULUS USV family, including construction of multiple ROMULUS 151 vessels and development of advanced manufacturing initiatives designed to accelerate delivery of autonomous maritime capability to allied fleets.

HII is a leader in integrating manned-unmanned maritime teaming and mission-enabling technologies to address rapidly evolving operational requirements for U.S. and allied naval forces.

This includes the ongoing collaboration with Babcock International Group to integrate autonomous launch and recovery capabilities for UUVs through submarine torpedo tubes, and Babcock’s ARMOR (Autonomous and Remote, Maritime Operational Response) Force initiative, developed to support the U.K. Royal Navy’s next-generation autonomous and crewed maritime programs. The ARMOR Force features integration of HII’s AI-enabled ROMULUS family of USVs as part of future autonomous fleet capabilities.

HII’s autonomous maritime systems support a broad range of missions, including mine countermeasures, ISR, seabed warfare, hydrographic survey, counter-unmanned systems operations, strike missions, and launch and recovery of unmanned aerial and underwater vehicles.
