Advancing Undersea Networking Technologies to Support Distributed Maritime Operations

The United States Navy is actively engaged in the development of advanced deepwater networking technologies aimed at enhancing its operational capabilities within the Distributed Maritime Operations (DMO) framework. This ambitious initiative seeks to create robust connections among subsea sensors, underwater drones, submarines, and other maritime platforms, thereby improving situational awareness and warfighting efficiency.

Networked Expeditionary Routing and Exchange for Undersea Systems (NEREUS)

A recent special notice regarding the “Networked Expeditionary Routing and Exchange for Undersea Systems” (NEREUS) outlines the Navy’s objective to integrate mature, proven undersea capabilities that can address specific mission requirements in seabed and subsurface warfare. The initiative focuses on the following key aspects:

• Enhancing Communication Reliability: The project aims to expand existing acoustic communications hardware by incorporating advanced networking and routing capabilities. This will facilitate reliable information transfer across numerous systems rather than relying solely on point-to-point links.
• Facilitating Cooperative Operations: The envisioned network will support seamless collaboration among unmanned underwater vehicles (UUVs), mobile and fixed sensors, as well as expeditionary nodes strategically deployed across expansive maritime regions.

DMO: Overcoming Adversarial Challenges

The DMO concept represents a sophisticated operational strategy designed to counter increasingly sophisticated anti-access/area denial (A2/AD) systems employed by global rivals, notably China and Russia. By integrating sensors and munitions across a broader network of aircraft and maritime vessels, the Navy aims to achieve several critical objectives:

• Diluting Targeting Focus: A dispersed fleet will make it significantly more challenging for adversaries to target U.S. forces, thereby increasing operational survivability.
• Expanding Offensive Capabilities: This networked approach will enhance the Navy’s capacity to project power effectively, particularly in high-stakes environments.
• Leveraging Advanced Technologies: The successful implementation of DMO will rely on innovations in artificial intelligence, automation, and resilient communication systems to ensure that manned and unmanned platforms can operate cohesively.

Integration with the Navy’s Hedge Strategy

This notice follows the unveiling of the Navy’s Hedge Strategy by Chief of Naval Operations Admiral Daryl Caudle. This recent strategic framework seeks to synchronize unmanned systems and autonomous platforms into tailored operational forces equipped to respond to a diverse range of threats that—while consequential—may not necessarily dictate the overall design of the fleet.

Administrative and Technical Considerations for NEREUS

The special notice details essential aspects of the NEREUS initiative, which encompasses:

• System Integration and Demonstration: Participants will be involved in lab and at-sea trials to validate operational feasibility and support the deployment of scalable undersea networking capabilities.
• High Technology Readiness Requirements: The Navy has emphasized the need for prototypes to possess a high Technology Readiness Level (TRL), indicating a priority to expedite the development and fielding of viable options for real-world applications.

Organizations interested in contributing to this project can engage through the Information Warfare Research Project, managed by Advanced Technology International (ATI). Note that consortium membership is a prerequisite for submissions, with responses due by February 19.

The implications of NEREUS and its role in bolstering DMO are significant, especially as the Navy seeks to maintain a competitive edge in a rapidly evolving global security landscape. A spokesperson from the Navy has yet to clarify the nomenclature of NEREUS—whether it was inspired by Greek mythology or relates to one of the earlier USS Nereus vessels, now decommissioned.

Enhancing undersea communications is a critical step as the Navy adapts to counter modern threats while supporting the interconnectedness of its formidable maritime assets.
