FIELD: weapon and ammunition.
SUBSTANCE: fragmentation part of fragmental and particle beam shells, generating the striking elements, contains the housing implemented in the form of multilayered annular set along axis of which an extended explosive charge, a device for dispersion of striking elements, and a contact and trajectory detonator are installed. The annular layers of the fragmentation part are implemented in the form of cylindrical spirals. Cross section of, at least, one spiral, mainly of all, is profiled. At least, one spiral of annular layer, preferably all, is made with pre-set pitch. In gaps between turns the ready striking elements are installed. The width of the named striking elements is equal to the width of gaps between spiral turns.
EFFECT: increased efficiency of shell.
