The problem of the initial phase of backward launching of the concentrated masses M[sub 1] and M[sub 2] by the compressed products of detonation, was solved in a closed form. It was found that the application of the Gurney formulae to estimate the initial velocity of the explosively driven elements of the shaped charge liner is burdened with a relatively large error. It results from the linear approximation of the flow velocity of the detonation products versus the Lagrangian coordinate (r). This approximation can be used when M[sub 1] = M[sub 2] > m, where m is the explosive mass. This condition in the shaped charge ammunition (HEAT), especially in warheads with a heavy casing and thin liner, is not satisfied. Besides, it was shown that the flow velocity of the detonation products changes linearly versus the Eulerian coordinate (x). The constructed solution can be used in the description of the process of shaped charge jet formation.
