A warhead assembly, comprising a cylindrical or conical metal body, having an inner wall with a plurality of channels or grooves extending parallel to a central longitudinal axis. Preformed fragments are inserted in the channels or grooves and a liner with an explosive fill is positioned within the metal body, retaining the preformed fragments in place. The warhead assembly on detonation produces a bimodal distribution of fragments with adequate mass and velocity with optimized mixed fragmentation that defeats or otherwise incapacitates a target or set of targets.

1.

1. A warhead assembly, adapted to be mounted at the head of a missile or projectile designed to deliver the warhead assembly to a target, said warhead assembly comprising, in combination: (a) a round metal body having an inner wall with a plurality of grooves extending parallel to a central longitudinal axis of the metal body;(b) a plurality of preformed fragments inserted in the grooves in said inner wall;(c) a liner, thinner than said metal body, positioned within the metal body and configured to retain the preformed fragments in place in said grooves; and(d) an explosive fill inside the liner; whereby the warhead assembly on detonation produces a bimodal distribution of fragments with adequate mass and velocity to create an optimized mixed fragmentation effect on the target that can defeat the target even when it is fitted with ballistic protection and/or when it comprises mixed targets of both enemy vehicles and personnel. 2. A warhead assembly, as recited in claim 1, wherein the liner physically separates the preformed fragments from the explosive fill. 3. A warhead assembly, adapted to be mounted at the head of a missile or projectile designed to deliver the warhead assembly to a target, said warhead assembly comprising, in combination: (a) a round metal casing having an outer surface with an aeroballistic shape and an inner wall with a plurality of grooves extending parallel to a central longitudinal axis thereof, said grooves being of such a size as to contain and fit preformed fragmentation elements;(b) a plurality of preformed metal fragmentation elements disposed in said grooves in the casing and balanced to provide for a stable gyroscopic spin of the warhead assembly and its delivery missile or projectile when in ballistic flight; and(c) an explosive charge within the metal casing; wherein distances between the grooves along the casing surface and depths of the grooves produce a fragmentation of the metal casing such that, on detonation of the explosive charge, the fragmentation is substantially shaped and defined by the grooves;whereby the combined effect of the metal casing fragmentation and the preformed fragmentation elements creates a terminal effect upon said detonation, exhibiting a multimodal distribution of fragments with an optimized effect on the target that defeats the target when it is either a single target or a mixed target of enemy vehicles and personnel. 4. A warhead assembly, as recited in claim 3, wherein the grooves extend forward along the inner wall of the casing from a vicinity of a base thereof which is attachable to the missile or projectile toward a nose thereof. 5. A warhead assembly, as recited in claim 3, wherein the grooves extend rearward along the inner wall of the casing from the vicinity of a nose thereof toward a base thereof which is attachable to the missile or projectile. 6. A warhead assembly, as recited in claim 3, wherein the grooves extend along the inner wall of the casing from a vicinity of a base thereof which is attachable to the missile or projectile to a vicinity of a nose thereof. 7. A warhead assembly, as recited in claim 3, wherein shaping of the casing fragments, upon detonation, is influenced by effects the preformed metal fragmentation elements interacting with an overall geometry of the metal casing, as determined by at least one parameter selected from the group consisting of: (a) casing wall thickness,(b) distance between the casing grooves,(c) depth of the casing grooves,(d) type of metal forming the casing, and(e) a forming process used in producing the casing. 8. A warhead assembly, as recited in claim 3, wherein the preformed metal fragmentation elements fit tightly into the grooves' inner channels and thereby substantially retain their form after detonation. 9. A warhead assembly, as recited in claim 3, wherein the shape of the preformed metal fragmentation elements is selected from the group consisting of spheres, notched rods, wire and cylindrically shaped rods. 10. A warhead assembly, as recited in claim 3, further comprising a nose cap fitted to the metal casing, on an end thereof opposite to the end which is fitted to the missile or projectile, said nose cap incorporating a fuze that initiates a detonation in a designated post firing or launch environment. 11. A warhead assembly, as recited in claim 3, further comprising a fuze fitted to the metal casing, at a base thereof which is fitted to the missile or projectile, that initiates a detonation in a designated post firing or launch environment. 12. A warhead assembly, as recited in claim 3, further comprising a liner, housing an explosive fill, positioned within the casing and retaining the preformed metal fragmentation elements in place, said liner physically separating the preformed metal fragmentation elements from the explosive fill. 13. A warhead assembly, as recited in claim 12, wherein the metal casing and the preformed metal fragmentation elements fitted into the grooves, coupled with the liner, form a configuration that mitigates the impact threat from an assailant projectile or fragment deep penetration into the cavity housing the warhead assembly's explosive fill. 14. A warhead assembly, as recited in claim 13, wherein a diversion of an assailant projectile or fragment attack reduces the peak pressure imparted directly on the explosive fill housed in the warhead assembly and thereby reduces the peak pressure point precluding the detonation of the warhead's explosive, reducing the overall sensitivity to outside stimuli of an assailant projectiles or fragments.
