REMUS 620 Unmanned Underwater Vehicle (UUV)

HII’s REMUS 620 is designed for greater efficiency and modularity, coupled with field-proven reliability, the REMUS 620 is the longest reaching UUV in its class. With a battery life of up to 110 hours and a range of 275 nautical miles, it delivers unmatched multi-day endurance, range, and stealth. Its modular, open architecture design and seamless payload integration, allow you to easily shift between any mission, above or below the surface, including mine countermeasures, hydrographic surveys, intelligence collection, surveillance, and electronic warfare.


Multiple REMUS 620s operating collaboratively, can be deployed from submarines, small manned or unmanned boats, amphibious ships, surface combatants, and helicopters. REMUS 620 can also be used as a platform to launch and operate other unmanned vehicles or payloads from beneath the sea—whatever your mission requires. Plan, monitor and analyze any of these missions with the new Odyssey™ Mission Management Software, part of the HII Odyssey™ suite of advanced autonomy solutions.
