This thesis builds on previously conducted experiments which measured the wave-induced loads that acted upon rectangular unmanned undersea vehicles of three different aspect ratios. Travis Turner, a graduate of Naval Postgraduate School, showed in his thesis in 2018 that the aspect ratio strongly influences specific loads, particularly the heave force. However, due to the limited number of aspect ratios tested, the functional relationship between the loads and the aspect ratio is unknown. This thesis identifies that relationship by numerically examining a broad range of aspect ratios by employing the Large Amplitude Motion Program (LAMP). The suitability of using LAMP is first confirmed by comparing the simulation results to the previously collected experimental results.
