Built on the REMUS Technology Platform, the REMUS 300 has compact and efficient core electronics, advanced autonomy and a common operating system that allows for interoperability with the entire REMUS family of systems. Its open architecture design and modularity enable integration of the latest hardware and software, with an optional hardware development kit and software development kit to enable third-party integration.

The REMUS 300 design incorporates feedback from hundreds of REMUS 100 users and provides the ability to exchange payloads, allowing application flexibility. Common applications include mine countermeasures, hydrographic survey, rapid environmental assessment, search and recovery, and marine research. Modular energy sections allow for field replacement of 1.5, 3.0 or 4.5 kilowatt-hour lithium-ion batteries enabling up to 10, 20 or 30 hours of endurance.

More than 500 REMUS UUVs have been sold to 25 countries worldwide. Standard configurations of the REMUS 300 can now be acquired internationally and commercially, with orders being accepted now for delivery in 2022.

The REMUS Autonomous Undersea Vehicle (AUV) was first developed in the late 1990s for the Woods Hole Oceanographic Institute by Hydroid, a subsidiary of Kongsberg Maritime. The man-portable class 36 kg REMUS 100 AUV is used by the U.S. Navy for shallow water mine countermeasures (MCM) and hydrographic reconnaissance. The Japanese Defense Ministry operates four of the REMUS 600 meter variants and one REMUS 100 for seafloor mapping and MCM.
