HII to Deliver Two Remus 620 Submersibles to NOAA

HII has secured an order from the National Oceanic and Atmospheric Administration to build two Remus 620 medium unmanned underwater vehicles.

HII Mission Technologies will work with W.S. Darley & Co. to build the Remus 620s, which will be delivered to NOAA by 2024. The UUVs will be fitted with a synthetic aperture sonar module, additional energy modules and auxiliary equipment.

NOAA will use the unmanned vehicles to generate high-resolution maps of the Gulf of Mexico and support efforts to restore the seafloor habitats damaged by the Deepwater Horizon oil spill, HII said Thursday.

The contractor unveiled the Remus 620 in November 2022. It is designed to support mine countermeasures, hydrographic surveys, ISR missions and electronic warfare. Other features include a 110-hour battery life, a range of 275 nautical miles, a modular and open-architecture design and HII’s Odyssey autonomy solutions suite.

Other UUVs part of the company’s Remus family are the Remus 100, Remus 300 and Remus 6000. All vehicles are built using open architecture and are designed to support missions such as marine geology, ISR and mine countermeasures.
