ABSTRACT:
An improved explosive warhead casing of novel fragmentation design that can e tailored for use with an increased number of weapons and thus impact a greater variety of targets with enhanced effectiveness. The casing is generally made up of a plurality of stacked ring-like elements. The adjacent outer peripheral portions of adjoining stacked elements are metallurgically bonded together in precise fashion such as by a laser device so as to form a unitized casing. A series of relatively spaced and longitudinally extending grooves are preferably formed on and about both the interior and exterior annular surfaces of the casing. Further, the series of grooves together with the bonds between the elements all cooperate to form a plurality of novel-shaped fragments where the configuration of each explosively formed fragment is subject to less distortion, metal flow, micro cracking, etc.; thereby approaching, with greater degree, the intended design configuration for each fragment. Since the casing is made up of bonded together elements, it can be formed by more than one manufacturing technique and different materials can be incorporated in the casing structure during its manufacture. Moreover, the casing is not limited to the usual cylindrical shaped configuration as its final shape or the formation of only one fragment grid pattern therein.
