This study undertakes an assessment of the military market for applications of an oxygen extraction technology being developed by DARPA at the aquanautics corporation. The potential applications identified through a literature search and technical discussions with developing agencies are subjected to an operational, technical, and economic feasibility analysis to determine which applications have The most military potential. Each application is examined to determine what technology base is required to support the development of the application. A development plan for the technology base and specific applications is generated.
