Abstract
An explosive device is disclosed which comprises a cylindrical casing filled with explosive charge. The charge is covered at one or both of its sides by a fragmentable lining which is fragmented by explosion of the explosive charge and movement of the shock wave in an effective direction. A recess is provided in the explosive charge which contains an inner booster charge surrounded by an outer annular booster charge. The inner and outer booster charges may be separated by a thin wall with openings in the wall communicating with spaced in the recess on sides of the outer booster charge. A damming lining covers a part of the outer booster charge and is spaced from the outer booster charge to form the spaces.
