The invention relates to a process for the manufacture of an explosive ammunition component with controlled fragmentation, comprising a charge of solid explosive contained in a metal casing internally clad with a sleeve externally provided with indentations. A rigid sleeve made of plastic or elastomer, externally provided with indentations and which has a form of a vessel provided with a single opening, is produced first of all, and then this sleeve is introduced, with the bottom first, into a metal casing comprising an opening and whose shape and dimensions are such as to allow the sleeve to clad the casing internally. A pasty or liquid explosive composition is next cast into the sleeve and the composition is then solidified.

Pyrotechnic igniter capable of being fitted in, and withdrawn from the throat of the nozzle of a propulsion unit. The igniter comprises parts bearing on the convergent section (1a) and on the divergent section (1b) of the nozzle. In order to permit the fitting and the withdrawal of this igniter at any time, while improving the conditions of ignition of the propellent charge, the igniter comprises, on the one hand, an internal rupture member (2) and, on the other hand, external means of fitting (3) which are capable of expanding radially, this internal rupture member initially maintaining the external means of fitting in a deployed position.
