HII is a leading developer of advanced unmanned and autonomous marine systems for commercial, defense and research applications.
Our untethered UUVs (unmanned underwater vehicles) and AUVs (autonomous underwater vehicles) have been used around the world in more than 30 countries, collecting valuable data for a wide variety of applications including marine research, hydrographic survey, MCM (mine countermeasures) and military ISR (intelligence, surveillance and reconnaissance).
We also provide a wide variety of engineering services and end-to-end support for maritime unmanned systems, including design, manufacturing, testing, operations, repair and maintenance.
We have extensive experience in providing full-spectrum services for UUVs and USVs (unmanned surface vehicles).
Our advanced next-generation UUVs are based around the REMUS Technology Platform, which features an open architecture, common operating system, and modular reconfigurable design. Providing reliable autonomy at depths down to 6000 metres, the flexible and scalable platform provides consistent high performance and a streamlined user experience.
The REMUS Technology Platform incorporates sophisticated search and navigation algorithms for robust autonomy, with advanced AI/ML enhancements. Missions are preprogrammed by the operator and the vehicle autonomously bottom tracks, avoids obstacles and communicates health status and location information.
REMUS UUVs can be customised to your exact requirements, with a modular architecture that allows sensors to be exchanged for different missions. The system also features swappable batteries with flexible energy options.
The REMUS design follows modular open system architecture (MOSA) principles, with data distribution service (DDS) middleware that enables adaptability, scalability and modularity of software. New sensors can be easily integrated without modifying the core vehicle control software, and an optional SDK is available for customer or third-party software integration.
Utilising the same operating system across the entire REMUS family reduces training costs, streamlines operations, and facilitates effective cybersecurity and data encryption.

Mine CountermeasuresREMUS autonomous marine systems can be equipped with side scan sonar to autonomously survey ports, harbours and large underwater areas, allowing operators to easily identify and classify mine-like objects for clearance.
Easily deployed from vessels of opportunity, REMUS unmanned undersea vehicles can cover large areas in a single sortie, making them ideal for locating targets such as downed aircraft and shipwrecks.
Rapid Environmental AssessmentUntethered REMUS UUVs are ideal for Rapid Environmental Assessment (REA), using side scan sonar to characterize the physical environment and ocean bottom to reduce risk during emergencies and disasters.
All our REMUS platforms can be equipped with a wide range of payloads and sensors enabling a variety of survey, monitoring and research missions. These include hydrography, marine geology and archaeology, mineral exploration and more.

Our long-endurance Seaglider AUVs are rated for depths down to 1000 metres and use changes in buoyancy to move through the water column. With no propellers or external moving parts, these ocean gliders can be easily deployed for long-term missions with minimal noise and disturbance.
Ideal for collecting high-resolution temporal and spatial data, Seagliders are equipped with satellite telemetry and can be fitted with a range of payloads such as echosounders, passive acoustic measurement (PAM) instruments, and chemical and temperature sensors.
