About HII Unmanned Systems
The REMUS family ranges from portable REMUS 130 and REMUS 300 vehicles to REMUS 620 and deep-water REMUS 6000 systems. Modular payload sections support mine countermeasures, seabed mapping, ISR, environmental monitoring and offshore inspection across depths from 100 to 6,000 metres.
Odyssey provides the common autonomy and command layer across REMUS underwater vehicles and ROMULUS surface vessels. Operators can plan, monitor and replan missions while the platforms coordinate sensors and behaviours locally. HII has delivered more than 750 REMUS vehicles and supports payload integration, simulation, training and lifecycle sustainment.
