The paper considers methodology and results of measuring parameters of the explosive and ballistic shock waves arising from the high-explosive and shaped charges explosion in water. In this case, parameters of the pressure and momentum fields during the shock waves motion were determined under conditions of the infinite fluid. Experimental results of the laboratory experiments are compared with the field tests, and are presented depending on the distance from the center of mass of the charge and direction of the sensors installation relative to the charge axis. Approximating dependencies are obtained to determine the maximum pressure and specific impulse values at the explosive and ballistic shock waves front during the high-explosive and shaped charges explosion. Diagrams are presented of the pressure field measurement and typical oscillograms at the point of the sensors installation. The results obtained could be used in assessing possibilities of wreaking destruction to an underwater barrier by high-explosive and high-explosive dual-purpose explosions.
