This thesis presents a unique approach to the conceptual design process for UUVs, thereby allowing strategic decision-makers to rapidly explore a given design space. The proposed MATLAB-based conceptual design program features five primary modules: a mission module, a hull module, a resistance module, a battery module, and a pressure vessel module. The final concept design results from an iterative process that considers the displacement, interior volume, and exterior volume of the total UUV system. To validate the proposed design algorithm, the author applied the best practices of modern naval architecture, marine engineering, ocean engineering, systems engineering, and submersible design.
