An underwater explosion is one of the possible threat which can occure during military operations and/or civilian usage. The ballistic protection systems are the method to reduce the impact of the high explosive (HE) charge blast wave. The aim of this paper is to present the influence of the shock wave on the flexible shell. The simulation of the underwater detonation is provided with use of the Finite Element Method (FEM). The influence of the distance between the HE charge and the flexible shell on its deformation was estimated. The results of the conducted analysis including explosion were compared with those obtained for the basic model with no explosion.
