From the notice

This is an Open ARA announcement pursuant to the authority of 10 U.S.C. §4023 Procurement for Experimental Purposes. AFRL is interested in receiving white papers related to the AFRL Energy Office’s mission to lead the discovery, development, delivery, and integration of energy science, technology, and innovation. The AFRL Energy Office’s intent is to decouple mission effectiveness from energy, water, and other resource and supply chain vulnerabilities through the identification, development, and demonstration of critical technologies for the Department of Air Force (DAF). Proposed solutions should be innovative and substantially improve national defense capabilities. While the Government describes discrete topic areas below, it also anticipates that certain comprehensive technology solutions, processes, methodologies, and prototypes may require multidisciplinary approaches that address two or more topic areas. The topic areas covered under this announcement may be used in any combination. The Government reserves the right to add, delete or modify the topic areas as necessary.
