A warhead device comprising explosive charges and effect elements or effect agents for incorporation in a missile. The warhead device consists of a number of modules or modular charges (1a 1f) arranged to be actuatable between two or more pivotal positions in the cross-section of the warhead device. Each module comprises outer walls (9 14) that one by one are directed outwards depending on the position or pivotal position assumed by the module. Each outer wall of each module comprises warhead effect elements and/or effect agents that differ from the other warhead effect elements or agents. The outer walls that are directed outwards simultaneously form or are part of the common outer wall of the warhead device, and project a selectable warhead effect from the warhead device.
