Low-Cost Bottoming Seabed Nodes for Unmanned Underwater Vehicle (UUV) Support

The Navy is seeking proposals for the development of modular, low-cost, high-endurance seabed nodes to support diverse subsea payloads, specifically for Unmanned Underwater Vehicle (UUV) support. These nodes must have standardized interfaces, a cylindrical form factor (19 inches diameter, 51 inches length, max 1,000 lbs dry weight), and operate independently or as part of a network for a minimum of 12 months (threshold) at depths up to 300 meters. Key requirements include pressure tolerance, anchoring capabilities in various seafloor conditions, and efficient power management. Initial payloads will focus on acoustic communication nodes with both long-range, low-data-rate horizontal communication (1-5kHz) and short-range, high-data-rate UUV communication, leveraging commercial off-the-shelf acoustic modems. The project involves a three-phase development plan: Phase I for concept design and feasibility, Phase II for prototype development and evaluation, and Phase III for transitioning the technology to Navy use and exploring dual-use applications in commercial sectors like oil, gas, and oceanography. The work will likely be classified in Phase II, requiring U.S.-owned and operated contractors with the ability to acquire and maintain secret-level facility and personnel security clearances, adhering to ITAR and EAR regulations.
