Abstract : An air dropped penetrator or projectile for a gun, (herein referred to as the munition), adapted for use in fracturing and penetrating a hard concrete target or a similar highly resistant target. In the most basic and generic form, the munition includes: a forward kinetic energy penetrator section, an aft follow-through ungula-shaped penetrator section, and a frangible intermediate section in the form of a tube which releasably interconnects the forward section and the aft section, thereby forming an integrated munition. Upon impact of the munition on the target, the frangible intermediate section breaks, thereby separating from the forward and aft sections, and also separating the forward and aft sections. The forward section fractures the concrete target and penetrates it; and, the aft section follows-through the fractured and penetrated target. Unlike the prior art, separation of this munition into its constituent sections is accomplished without the use of any explosive/propellant to initiate and to cause separation. (Author)
