Patent ID: 8276520

Claim:
A fragmentation warhead comprising manual selection means for generating larger fragments versus smaller fragments upon detonation, said warhead comprising: a cylindrically shaped fragmenting outer warhead; a cylindrically shaped explosive charge; a cylindrically shaped first inner liner coaxial with, the explosive charge; a cylindrically shaped second inner liner disposed immediately inside the fragmenting outer warhead; between the inner and outer liners are a number of stacked identical circular ring mechanisms all coaxial to the explosive charge, to the liners and to the outer warhead; said ring mechanisms each having a planar thin ring integral with a multiplicity of like material three dimension rectangular shaped blocks which are positioned equidistantly on one face of, and around the circumference of said ring, equidistant with open areas between the blocks around the circumference of said ring; and wherein each ring mechanism is capable of being individually positioned by rotating the ring mechanism coaxially with respect to another ring mechanism or ring mechanisms so that the outer faces on the blocks appear in an outwardly looking checkerboard pattern to form smaller size fragments upon detonation of the warhead; and wherein each ring mechanism is capable of being individually positioned by rotating the ring mechanism coaxially with respect to another ring mechanism or ring mechanisms so that the outer faces on the blocks appear in an outwardly looking straight line pattern to form larger size fragments upon detonation of the warhead; and wherein selected ring mechanisms variously desired to be held stationary to form a desired block pattern to one another can be joined by a rod through holes and slots in each ring mechanism; and a spring mechanism to hold various ring mechanisms in one default position unless moved manually and then locked into a new desired position.
