Advanced Power and Energy for Undersea Applications

The Advanced Power and Energy for Undersea Applications program aims to develop component, subsystem and system technologies for advanced high-energy density and power density propulsion systems, and enabling increased endurance and reliability in an air-independent environment.

The program has an annual review of all current performers to cover current Navy science and technology (S&T) efforts in the areas of air-independent energy, propulsion technologies for unmanned undersea vehicles (UUVs) and undersea weapons. The review discusses S&T progress to date in these efforts and fosters discussion and future collaboration among the performers, while helping to formulate future S&T strategies.
