ABSTRACT:
The invention concerns a practice war head device for an artillery rocket, comprising a frusto-conical head element having a hollow nose section and a hollow skirt section, an impact detonator mounted in said nose section, a tubular jacket connected to the skirt section, a tubular dividing element concentric with the tubular jacket together defining an annular volume, a fog producing substance based on a carbon halogen or halogen carbohydrate substance and reactive metal or metal oxide powders in said annular volume, and an ignition core of a quick-reacting ignition substance capable of high gas formation in the tubular dividing element, which is characterized in that the fog producing substance is loosely packed in the annular volume, that closure elements closing off said annular volume are provided at the nose side and base side of the annular packing, that at least the nose side closure element is displaceable towards the fog producing substance packing and that the connection between the skirt section of the head element and the tubular jacket, the connection between the central portion of the head element and the tubular dividing element, and the base of the skirt section, are constructed so that upon impact of the war head device, the base of the skirt section will be displaced into the annular volume to thereby compress the fog producing substance.
