REMUS UUVs
Proven Unmanned Undersea Systems for Critical Missions
Modern missions demand reliable, autonomous undersea systems that can operate across depths, integrate with multi‑domain assets, and deliver one-way kinetic and non-kinetic effects when needed. Existing solutions lack the interoperability, endurance and flexibility required for today’s complex undersea environment.
HII’s REMUS unmanned underwater vehicles (UUVs) provide a proven, mission‑ready advantage across defense, research and commercial operations, pairing decades of reliability with a modular, open‑architecture design that scales. Supporting ISR and mine countermeasures, anti‑submarine warfare and electronic warfare, REMUS operates independently or alongside manned platforms like Virginia-class nuclear submarines to expand operational reach.
