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: <ul type="disc"><li style="margin-top:6pt; margin-bottom:6pt;">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.</li><li style="margin-top:6pt; margin-bottom:6pt;">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.</li><li style="margin-top:6pt; margin-bottom:6pt;">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.</li><li style="margin-top:6pt; margin-bottom:6pt;">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.</li></ul> 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.
