Claim 0:
1. A warhead with asymmetric initiation comprising:
an inner explosive charge; and
a tubular structure;
wherein the warhead is connectable to detonator means and target sensor for activating the detonator means;
wherein the tubular structure comprises a wall and a central cavity for the inner explosive charge, the tubular structure having an outer diameter DO, an inner diameter DI, a wall thickness T=0.5×(DO−DI), a front end, a rear end, a central axis connecting the front end and the rear end and a length L measured parallel to the central axis, an inner surface facing the central cavity and an outer surface;
wherein the warhead further comprises a fragmentable material adjacent to the outer surface of the tubular structure;
wherein the wall comprises a plurality of bores angularly and/or axially spaced from each other and extending from the outer surface in a direction toward the inner surface;
wherein the bores are filled with an explosive substance by means of isostatic pressing;
wherein the outer surface of the wall is provided with a plurality of channels and/or a plurality of channels are provided within the wall;
wherein the plurality of channels connect at least a part of the plurality of the bores and are also filled with the explosive substance by means of isostatic pressing;
wherein the plurality of bores are connected to a detonator by means of the explosive substance provided in the plurality of channels; and
wherein the depth C of the plurality of channels on the outer surface or the diameter of the plurality of channels provided within the wall is in the range of 0.2 T<C<0.8 T;
wherein the depth of the plurality of bores is greater than depth C of the plurality of channels; and
wherein the entirety of all of the plurality of channels has a volume v, which is smaller than 15% of a theoretical volume V=0.25πL (DO2−DI2) of the tubular structure if the tubular structure had no channels.
