text: In a warhead having a first explosive material with a cylindrical bore therein co-extensive with its length and an elongated cylindrical initiator disposed within said bore extending between opposite ends thereof, means for detonating said initiator substantially at a point along its length, said initiator being of such a character that when detonated at said point it produces a detonation front which propagates in axial and radial directions, a first tube disposed between the initiator and the wall of the bore surrounding and engaging said initiator and having decreasing wall thickness in a direction away from said point and constructed of a material having the property of delaying the propagation of said detonation front, said first tube and the wall of the bore being radially spaced to protect the first explosive material from damage by outward propagation of shock wave and particles of said first tube which emerge from the first tube ahead of the detonation wave, whereby a detonation front is efiFected in which all parts of the radially propagating portions of the front substantially simultaneously reach the wall of the bore to cause simultaneous initiation of the warhead along its length.
