This study involves the force and moment calculations using the scaled and full-scale geometries of the Autosub submarine. The scale factor of the submarine is used as 1.346 according to the model size used in the experiments. Computational fluid dynamics calculations have been performed using RANS equations and the k-ω turbulence model. The resistance analyses have been conducted for speeds ranging from 0 to 2 m/s. Static drift analyses have been conducted between the range of 0o to 10o degrees drift angles at 2 degrees intervals. A mesh independence study has been carried out to determine the adequate mesh density. The mesh structure has been determined in the analyses for 6 degrees of drift angle and this mesh structure is used for other drift angles, and the results have been compared with experimental results from the open literature. Full-scale resistance analyses have been conducted, and the calculated resistance forces have been compared with the experimental and empirical data. The force and moment values obtained from static drift and resistance analyses are found to be consistent with experimental results presented in the literature.
