REMUS 100

REMUS 100 is a compact autonomous underwater vehicle for coastal survey, environmental monitoring and defence work. The 2016 Hydroid generation introduced an ARM-and-FPGA electronics board, a conformal Doppler velocity log, selectable inertial navigation and configurable battery and nose sections. Its modular layout lets operators fit sensing payloads for untethered routes in water up to the model’s 100-metre depth class.

HII acquired Hydroid from Kongsberg in 2020 and continues the REMUS line. A legacy REMUS 100 operated by the Australian Maritime College completed 935 deployments over seven years, with two days of downtime attributed to material issues, while supporting training for more than 400 Royal Australian Navy operators. HII’s later REMUS 100M sheet lists a ten-hour estimated endurance and 67-kilometre range at three knots; those 100M figures should not be read as specifications for every earlier REMUS 100 configuration.
