HII USV Reaches 30% Completion, On Track for 2026 Sea Trials
.S. Navy, U.S. Marine Corps, joint forces and allies. They deliver high-endurance, sustained open-ocean autonomy with a focus on lethality, cost efficiency and scalability.The family of USVs will support missions including intelligence, surveillance and reconnaissance, counter-unmanned air systems, mine countermeasures, strike, and the launch and recovery of unmanned underwater vehicles (UUV) and unmanned aerial vehicles (UAV).Paired with HII’s REMUS UUVs, ROMULUS extends undersea reach and supports a scalable dual-domain force package built for distributed maritime operations.This ROMULUS prototype
StrateSea Technology Selected for NATO DIANA 2026 Challenge Program
, contested, and bandwidth-limited environments while maintaining transparency and mission relevance.As part of the DIANA program, StrateSea will further develop and validate its technology within the Maritime Operations challenge area, focusing on multi-sensor fusion, subsea domain awareness, mine countermeasures, and autonomous maritime workflows.Beginning in January 2026, DIANA participants receive contractual funding and access to a network of accelerator sites and more than 200 test centers across the 32 NATO nations.Through DIANA, companies work directly with military end-users, technical experts
Hybrid Theory: Multi-Domain Unmanned Systems are Blurring Maritime Boundaries
200 meters for up to five days. In addition to surface surveillance, the Triton’s body payload capacity of 23 kilograms (with additional space in the wing and keel) enables underwater survey and intelligence operations, making it well suited for missions such as anti-submarine warfare (ASW), mine countermeasures (MCM), and critical infrastructure protection. The vehicle is designed for one or two-person launch/recovery from ship or shore, and a small logistics footprint allows it to be easily transported and deployed in remote or contested regions.An Ocean Aero Triton unmanned surface vessel (USV)
Kongsberg Discovery, MacArtney Partner for ROTV Surveying and Inspection Capability
with MacArtney’s platforms, we can now offer a unique blend of technology and flexibility," said Helge Uhlen, Vice President, OT Sales, Kongsberg Discovery. Uhlen notes applications include, but are not limited to, seafloor mapping, pipeline and cable inspection, wide-area search tasks, mine-countermeasures, and more. The flexibility of the solution allows for operations in either shallow coastal areas, or at depths down to 1,000 meters, depending on the specific platform
Deeply Innovative: Drivers in Subsea Defense
long been known for its Gemini imaging sonars, but its MicronNav USBL system is a standout in miniaturized navigation. Designed for small vehicles and diver applications, MicronNav provides real-time tracking, positioning, and data transfer in tight, cluttered spaces - critical for operations like mine countermeasures (MCM) and covert coastal operations.MicronNav USBL system.

national security and maritime operations.The REMUS line of UUVs is fielded in more than 30 countries, including 14 NATO members. Known for modularity, endurance, and proven performance, REMUS vehicles are deployed across defense, commercial, and research sectors for critical missions including mine countermeasures, hydrographic survey, intelligence gathering, and environmental monitoring.Over 90% of REMUS units delivered in the past 23 years remain in service.The REMUS open-architecture design allows rapid payload integration, enabling mission-specific configurations and future tech insertions, key
Thales, HII Partner to Develop Autonomous Undersea Mine Countermeasure Capabilities
; multi-aspect synthetic aperture SAMDIS 600 sonar with HII’s modular, long-endurance REMUS 620 UUV. Together, the systems deliver advanced autonomous mine detection, classification, and imaging, offering naval forces and partners around the world enhanced capability for undersea security, mine countermeasures, and subsea infrastructure monitoring.The exercise, completed at the end of August at the HII Pocasset facility (Massachusetts, USA), marks a milestone in advancing autonomous undersea mine countermeasure capabilities
