A penetrator having a plurality of stacked penetrator segments is disclosed. One or more of the segments contains an explosive element Each segment has a nose portion and a rear portion. The rear portion of each segment has a rearwardly opening cavity therein and a plurality of fins pivotally mounted thereon. The segments are stacked such that the cavity of the forwardmost segment contains the nose portion of the following segment, and the following segments are similarly positioned such that the nose portion of each following segment is positioned in the cavity of the immediately preceding segment. The fins of each segment are restrained in a stowed position when the cavity of the respective segment contains the nose portion of a following segment. Upon initiation of deployment of the penetrator, aerodynamic drag against the tail portion of the rearmost segment causes the rearmost segment to separate from the stack of segments by withdrawing from the cavity of the preceding segment, which thereby allows the fins of the preceding segment to deploy, which in turn causes that segment to separate from the remaining stack of segments. Each segment aerodynamically separates from the stack in a like manner, until all of the segments have separated. The penetrator is then in a fully deployed configuration such that each segment can separately impact a target. When a segment containing an explosive element impacts the target, the explosive element contained therein explodes.

[ What is claimed is:] [1.] A penetrator for impacting a target, said penetrator having a leading end, a trailing end, and a longitudinal axis extending between said leading end and said trailing end, said penetrator comprising:a plurality of penetrator segments positioned in axial alignment with each other along the longitudinal axis of said penetrator to form a stack, each of said penetrator segments having a nose portion and a rear portion, said plurality of penetrator segments including a leading penetrator segment, at least one intermediate penetrator segment, and a trailing penetrator segment;said leading penetrator segment being positioned at the leading end of said penetrator, the rear portion of said leading penetrator segment having a rearwardly opening cavity therein, the rearwardly opening cavity being shaped to receive a nose portion of a forwardmost one of said at least one intermediate penetrator segment;the rear portion of each of said at least one intermediate penetrator segment having a rearwardly opening cavity therein, the rearwardly opening cavity of each of said at least one intermediate penetrator segment being shaped to receive a nose portion of an immediately rearwardly positioned penetrator segment, the rear portion of each of said at least one intermediate penetrator segment having a plurality of fins pivotally mounted thereon, each of the fins having a stowed position and a deployed position, the nose portion of each of said at least one intermediate penetrator segment being positioned within the rearwardly opening cavity of an immediately preceding penetrator segment; andsaid trailing penetrator segment being positioned such that said at least one intermediate penetrator segment is located between said leading penetrator segment and said trailing penetrator segment, the nose portion of said trailing penetrator segment being positioned in the rearwardly opening cavity of a rearmost one of said at least one intermediate penetrator segment such that the nose portion of said trailing penetrator segment engages an element associated with each of said fins of the rearmost one of said at least one intermediate penetrator segment to thereby prevent the fins of the rearmost one of said at least one intermediate penetrator segment from pivoting from their stowed positions to their deployed positions, the rear portion of said trailing penetrator segment having a tail portion, said trailing penetrator segment having an explosive element contained therein;whereby upon initiation of deployment of said penetrator, aerodynamic drag against the tail portion of said trailing penetrator segment decreases the velocity of said trailing penetrator segment, thereby causing said trailing penetrator segment to withdraw from the rearwardly opening cavity of the rearmost one of said at least one intermediate penetrator segment, whereupon the fins of the rearmost one of said at least one intermediate penetrator segment pivot from their stowed positions to their deployed positions; whereupon aerodynamic drag against the thus deployed fins of the rearmost one of said at least one intermediate penetrator segment decreases the velocity of the rearmost one of said at least one intermediate penetrator segment; and when the fins of the forwardmost one of said at least one intermediate penetrator segment are in their deployed positions, aerodynamic drag against the fins of the forwardmost one of said at least one intermediate penetrator segment decreases the velocity of the forwardmost one of said at least one intermediate penetrator segment, thereby causing said forwardmost one of said at least one intermediate penetrator segment to withdraw from the rearwardly opening cavity of the leading penetrator segment; whereupon said plurality of penetrator segments have aerodynamically separated from each other and each penetrator segment can separately impact the target in sequence and the explosive element contained within said trailing penetrator segment can explode.
