Recently, the submarine missions are often evolving into operating to littoral areas, which require operating in shallow water. Such shallow water operations strongly contrast with the traditional ones due to the effect of a close to free water surface expressed mainly by surface suction force. This influence is particularly important for submarine maneuverability accounting for restricted area available. The prediction of submarine behavior in similar conditions requires adequate mathematical model and understanding of the additional hydrodynamic load generated near the surface region. The paper is aimed for better understanding of these issues and relating to development of a submarine simulation model, the experimental program of towing and PMM captive tests of DARPA Suboff submarine model were conducted at a towing tank. The influence of phenomenon such as effect of a close to free surface and Froude number at hydrodynamic forces and moments including control surfaces effectiveness were investigated and also was estimated directional stability of motion in horizontal plane.
