Underwater Signatures (Electromagnetic): Seabasing Logistics and Amphibious Craft

This work supports the Navy’s interest in advanced sea platform performance science and technology (S&T), advanced sea platform survivability S&T, submarine S&T, and seabasing S&T.

  • Underwater electromagnetics discovery and invention (D&I):
    • Emphasis on reliable prediction of ship and submarine underwater electromagnetic (EM) signatures
    • Development of prediction methods combining computational with experimental data incorporating both hysteretic, permanent magnetization models and electrochemical surface models
    • Improved, low-cost, underwater electromagnetic signature measurement techniques based on small UUVs rather than large-fixed ranges
  • Ultra-Heavy Amphibious Connector (UHAC): Combines the amphibious capabilities of a Landing Craft Air Cushion (LCAC) with the load-carrying capacity of a Landing Craft Utility (LCU)
  • Pipefish:
    • An affordable means to distribute fuel across a large theatre environment
    • All-fabric structures achieving double-hull equivalent environmental compliance

Research Concentration Areas

  • Underwater Signatures: Future ship and submarine survivability require accurate EM signature prediction. D&I work will lead to greatly improved tools and methods to understand, measure and model these signatures.
  • Pipefish:
    • Increase operational persistence and flexibility for distributed operations in contested / uncertain environments
    • Reduced visibility fuel delivery and low acquisition cost compared to an oiler / tanker

Research Challenges and Opportunities

  • Underwater Signatures:
    • S&T investments to ensure reliable, real-time knowledge and management of underwater electromagnetic signatures
    • Reduce risk with respect to meeting signature requirements through a combination of physical-scale models (magnetic and electrolytic) and computational, physics-based models
    • Reduce the number of electromagnetic sensors required to monitor and self-assess electromagnetic signatures
  • UHAC Amphibious Craft: Develop and test new technologies to improve performance in ground-based and sea-based amphibious assault operations and sea-to-shore logistical support capabilities
  • Pipefish Fuel Storage: Develop and test inflatable, double-walled fuel storage, transport and transfer system for bulk fuel logistics to include:
    • Robust, outer membrane structure
    • Internal, fuel containment bladder structurally and functionally integrated into outer membrane
    • Potential for future integration with an autonomous / semi-autonomous propulsion unit
