Abstract: The invention relates to a slug generating charge incorporating an explosive charge arranged in an envelope and a liner intended to be set into motion by the detonation of the explosive. The liner, whose thickness decreases between a central part and its periphery, is in contact with the envelope. A plate is placed between the explosive charge and the liner. The plate is of a diameter equal to the inner diameter of the envelope and is in contact with the liner at least at the latter's thinned peripheral part. The material of the plate is selected such that it reduces the velocity transmitted to the peripheral part of the liner by the explosive charge upon its ignition.
