A mortar ammunition round which contains at least three fragment producing regions covered by a threadably removable aluminum cowling. Detachment of the cowling provides access to several of the fragment producing regions which are located on a removable cup device. A different cup device may then be selectively inserted and the cowling replaced, forming a new mortar round of different select performance capabilities.

A multi-purpose munition operates in either a blast mode or a fragmentation mode according to a user input. When operating in the fragmentation mode, a fuze initiates a main explosive fill of the munition which in turn disperses fragments formed from a fragmentation layer of the munition. When operating in a blast mode, prior to initiating the main explosive fill, the fuze initiates a secondary energetic layer which discards the fragmentation layer. The fuze then initiates the main explosive fill thereby producing a blast effect.

Multi-purpose state changing munition

A warhead includes a body, a patterned liner made of plastic, and an explosive charge disposed within the liner. The liner pattern is formed of gaps and liner elements. The explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements. Upon detonation of the explosive charge and because of the temporal delay in transmitting the detonation energy between these two sets of sections, the warhead body is caused to shear and break into fragments with controlled size. The use of plastic as the liner material also provides a welcome safety feature for this warhead. In the event of unwanted heat ignition, the plastic (which is also low melt temperature material), would melt to seal the explosive and would also flow. Because of the plastic, neither sudden pressure nor heat/ignition inside the round, would therefore be as catastrophic.
