Target Strength is one of the main parameters in the sonar equation that is calculated for active sonar. In this paper, the Target Strength of the Russian 941 Akula Class submarine as one of the largest submarines in the world is estimated. We first subdivide the submarine into three cylindrical, rectangular, and hemispherical geometric shapes, and compute the target strength each at different angles and constant frequency, then aggregate all three geometric shapes and calculate the total target strength of the submarine. Finally, modeling and simulation for this submarine is presented. Results show the maximum target strength of this submarine at the normal angle is 109.26 dB and the average target strength of the cylindrical and rectangular section and the nose at different angles is 15.193 dB
