The paper considers specifics in deformation and destruction of the axisymmetric steel plate rigidly fixed in a cylindrical matrix with a sealed air cavity placed in water and exposed to impact of the high-explosive and shaped charges blast. Results of experimental study of the barrier through destruction depending on the center of mass of the explosive charge distance to the barrier and its thickness under separate action of high-explosive, cumulative and combined action of the cumulative high-explosive underwater blast are presented. On the basis of metallographic analysis, the barrier destruction mechanism is presented by formation and development of the rupture main macro-cracks associated with the edge of the hole from the cumulative jet action.
