HII press release
Global defense and technologies partner HII announced today the delivery of three REMUS 100 unmanned underwater vehicles (UUVs) to the United Kingdom’s Royal Navy. The new systems bring enhanced endurance and the latest generation of sensors and payloads, allowing for increased data quality and mission efficiency.
“We’re proud to continue our longstanding partnership with the U.K. Royal Navy. Our newest REMUS 100s will bolster their existing fleet with increased capability for the U.K.’s subsea autonomous operations.”
Duane Fotheringham, President of the Unmanned Systems business group at HII’s Mission Technologies division
With these new systems, the U.K.’s Ministry of Defence has acquired a mix of REMUS 100s and 600s used for mine countermeasure operations over the last 20 years. The Ministry of Defence’s first two REMUS 100s, acquired in 2002, are still in operation today.

“On behalf of the frontline users, I’m delighted to accept into service this refresh of REMUS 100,” said Cmdr. Rory Armstrong, mine warfare lead at the U.K. Navy Command Headquarters. “Our use of the REMUS family of vehicles over the last two decades has paved the way for a future mine countermeasures capability with autonomy at its core. These vehicles represent an exciting evolution of our existing small AUV fleet and will make a valued contribution to the Royal Navy as a force for good both in home waters and on an expeditionary basis.”
HII has sold more than 600 UUVs to 30 countries worldwide, including 14 NATO member countries like the U.K.
About REMUS 100M UUV

The REMUS 100M mine countermeasures variant is a small class, two-man portable unmanned underwater vehicle (UUV) that can be rapidly deployed to hazardous areas to collect data in support of defense missions. The open architecture and modularity of the REMUS Technology Platform facilitates increased capabilities, interoperability and applications while decreasing risk and cost.
The REMUS 100 is used by expeditionary warfare forces worldwide to conduct shallow-water MCM and port and harbor clearance. Using side scan sonar, the REMUS 100 surveys large areas autonomously which allows operators to review the data away from the mine field to identify and classify mine-like objects.
These UUVs are rapidly deployable from any vessel of opportunity and provide large area coverage on a single mission, making them ideal for SAR operations. Side scan sonar and precision navigation provide highly accurate data to locate targets, including downed aircraft and sunken ships.
Key Features :
- Two-man portable, small-class UUV
- 100-meter depth rated
- Up to 10-hour mission duration
- Speeds up to 4.5 knots
- Open architecture
- Low logistics
- Rapidly deployable from any vessel of opportunity
