When assessing the effectiveness of ammunition designed to destroy various aerodynamic and ballistic targets, as the initial data on the vulnerability of the destruction objective, we use indicators obtained during experimental studies of the processes of fragments and fragment flow collision with various fragments of the target design. The results depend not only on the speed and mass of individual fragments, but also on their shape and location in the flow. The paper gives the results of the testing of an explosive thrower which provides the creation of a high-speed, i.e. ~5 km/s, flow of fragments of a given shape. Findings of research show satisfactory agreement between the results of calculations carried out in two- and three-dimensional statements with experimental data on high-speed throwing of a group of compact, parallelepiped, steel preformed fragments weighing 20 g each
