A shaped charge includes an explosive charge having a cavity lined with a laminate liner, the laminate liner comprising a primary liner located adjacent the cavity which forms a non-jet penetrator on detonation, and one or more supplementary liners each of which is less dense than the adjacent liner nearer the cavity. On detonation the liners form a series of penetrators, those formed by the supplementary liners acting to clear a path through an obstruction in front of a target to produce a more efficient attack on the target by that formed by the primary liner.
