HII recently introduced the REMUS 620 medium-range unmanned underwater vehicle, an autonomous robotic submarine that combines artificial intelligence with 275 nautical miles (509 km).

Based on HII’s REMUS 300 UUV, the mid-range REMUS 620 is designed to support current and anticipated US Navy and Special Forces operations with an improved battery system with a 110-hour service life. This not only increases the REMUS 620’s uptime, but also provides ample range for transport to and from operational areas. Potential missions include mine countermeasures, hydrographic surveys, reconnaissance operations, surveillance and electronic warfare.

The REMUS 620 features a modular open architecture and includes HII’s Odyssey Autonomy Package, which gives the drone the ability to collaborate with artificial intelligence, autonomous condition monitoring and other robotic tools.

According to HII, the REMUS 620 can be launched from submarines, small manned or unmanned vehicles, amphibious vehicles, surface warships and helicopters. It can also deploy robotic vehicles and payloads underwater.
