US military shipbuilding company HII announced that its Mission Technologies division has developed a new REMUS 620 medium-range unmanned underwater vehicle (UAV).

Based on the design philosophy of the successful REMUS 300, selected by the US Navy as the Lionfish Small UUV application, the REMUS 620 has a battery life of up to 110 hours and a range of 275 nautical miles, providing unmatched mission capability. mine countermeasures, hydrographic surveys, collection and electronic warfare.

“Maintaining advanced strategic advantage requires the ability to conduct multiple operations from the sea,” said Duane Fotheringham, head of the unmanned systems business group at Mission Technologies. “REMUS 620 is the first mid-size UUV designed to accurately reproduce a range of advanced effects above and below water at long range.”

Designed to support naval and special operations forces operations, the REMUS 620 features a modular, open architecture design that enables seamless integration of payloads and a range of advanced HII Odyssey™ autonomous solutions for intelligent robotic platforms.

The REMUS 620 is the same size and weight as the first production mid-size UUVs: the MK 18 Mod 2, the Littoral Battleship Sensing-Autonomous Submarine Vehicle (LBS-AUV) and the LBS-Razorback systems operated by the US Navy Mine Countermeasure Service.

Multiple REMUS 620s working together can be deployed from submarines, small manned or unmanned boats, amphibious assault ships, surface warships and helicopters. The REMUS 620 can also be used as a platform to launch and control other unmanned vehicles or payloads from the sea.

The REMUS 620 is equipped with multiple batteries rated for 110 hours of operation and a range of 275 nautical miles per mission, providing unmatched multi-day endurance, range and stealth.

Extended REMUS battery life allows the UUV to traverse a much longer route to mission space and return than previously allowed by mid-range vehicles. The energy modules are replaceable, allowing you to quickly replace and connect alternative energy sources as they become available.

The REMUS 620 is built using advanced core electronics, navigation and communication systems, and the vehicle’s open architecture can now be enhanced with HII Odyssey™, a suite of advanced autonomous solutions for intelligent robotic platforms. The sub includes the new Odyssey Mission Management software. The standard REMUS 620 synthetic aperture sonar payload can be modified or expanded to perform multiple missions, including intelligence, surveillance and reconnaissance, and cyber and electronic warfare operations.
