Abstract : The initial focus of the work performed in this study was to determine the feasibility and utility of different approaches to the buoyancy control system (elevator) required for an expendable autonomous profiler (XAP) which would be an air-deployable, A-size sonobuoy-like device. Two approaches were analyzed in detail, one using a hydraulic elevator and the other using a compressed gas elevator. Some conclusions were reached regarding the recommended technical approach for building XAP prototypes. The certification process for sonobuoys was investigated as well as the certification requirements for using lithium-based batteries. Finally, a functional description and initial cost estimates for a potential XAP prototype were developed.
