The NEREUS project aims to enhance and expand the US Navy’s existing communications systems, enabling crewed/uncrewed seabed and subsurface missions.

The US Navy (USN) plans to develop and demonstrate an underwater networking capability to support combined seabed and subsurface warfare missions with crewed submarine platforms and uncrewed underwater vehicles (UUVs).

Titled Networked Expeditionary Routing and Exchange for Undersea Systems (NEREUS), the project will leverage and enhance the branch’s existing, fielded acoustic communications hardware to allow it to conduct distributed maritime operations.
