The Government is seeking a prototype effort to develop and demonstrate a high Technology Readiness Level (high-TRL) undersea networking capability to support distributed maritime operations, with a focus on Seabed and Subsurface Warfare (SSW) mission needs. The project will leverage existing, fielded acoustic communications hardware and extend it with networking and routing functionality to enable reliable information exchange beyond simple point-to-point links. The resulting capability will support cooperative operation among unmanned underwater systems, fixed and mobile sensors, and expeditionary nodes deployed across wide maritime areas. • The scope includes system integration, laboratory and at-sea demonstration, and participation in deployment and recovery activities to validate operational feasibility to support fielding of a scalable, resilient undersea networking capability. • The project requires consortium membership with the Information Warfare Research Project (IWRP), a consortium managed by Advanced Technology International (ATI). • The goal is to develop a high-TRL undersea networking capability to support distributed maritime operations.
