REMUS 620 UUVs

The REMUS 620 is HII’s second‑generation medium‑class UUV, engineered to deliver exceptional endurance, mission capacity and collaborative autonomy through the cross-domain Odyssey^™ asset management suite. With a modular, open‑architecture design and field‑proven reliability, it offers unmatched flexibility for operations above or below the surface.

The first recovery of a second‑generation REMUS 620 into a Virginia‑class submarine torpedo tube marks a major milestone in enabling the U.S. Navy Submarine Force autonomous undersea vehicle launch and recovery effort.

The REMUS 620’s extended battery life—up to 110 hours—and 275‑nautical‑mile range make it the longest‑reaching UUV in its class. Its versatility extends further when multiple vehicles operate collaboratively. The REMU 620 can be deployed from submarines, small manned or unmanned boats, amphibious ships, surface combatants, and helicopters. It can also serve as a host platform to launch and operate other unmanned vehicles or payloads from beneath the sea.

Mission planning, monitoring and analysis are powered by Odyssey^™ Mission, part of the HII Odyssey^™ advanced autonomy suite.
