An improved inertial armor-piercing penetrator projectile wherein the axial length of the projectile is a relatively large multiple of its diameter. The projectile includes a pre-penetrator and a main penetrator with a nose and a tail. The forward portion of the main penetrator is operatively connected to the tail of the pre-penetrator. The pre-penetrator comprises a plurality of partial cores which are axially arranged one behind the other and are operatively connected to each other at mutual coupling regions so as to form a stack. The stack of partial cores includes centering and/or fixing means which may take various forms and can be selectively exchanged. The cover and the centering and/or fixing means are adapted to achieve a predetermined fracturing or separation upon the application of a predetermined load. Thus, the centering and/or fixing means include a weakened portion where the fracturing or separation occurs. The construction and arrangement of the partial cores is such that each partial core differs from the adjacent partial core with respect to dimensions and/or material so that a front partial core will sufficiently disintegrate upon impact prior to the next following partial core reaching the target.

An improved inertial armor-piercing subcaliber penetrator projectile, having a relatively large length to diameter ratio, and including a front pre-penetrator having a nose and a tail, and having a main penetrator operatively connected to said tail of said pre-penetrator, said pre-penetrator compris

An improved inertial armor-piercing subcaliber penetrator projectile, having a relatively large length to diameter ratio, and including a front pre-penetrator having a nose and a tail, and having a main penetrator operatively connected to said tail of said pre-penetrator, said pre-penetrator comprising a stack of predetermined mass of a predetermined number of partial cores, each partial core being of predetermined length and having an essentially circular cross-section of uniform corresponding diameter, a front end surface, and an aft end surface, each partial core being separable from the stack of partial cores and being exchangeable for an other partial core of different mass, each partial core having at least one sharp edge on its front region, the front end surface of each partial core abutting the aft end surface of the immediately adjacent partial core to thereby form a predetermined number of butt zones, the major portion of each of two corresponding abutting surfaces of each butt zone defining a plane which is normal with respect to the central longitudinal axis of said penetrator, each butt zone comprising centering means to fixedly connect adjacent partial cores to each other, said centering means provide a predetermined fracturing or separation upon the application of a predetermined load, each butt zone forming an individual preset fracturing area, the predetermined load to be applied to achieve said fracturing or separation in said area stepwisely increasing from the front-most butt zone to the one next rearwardly disposed up to the front end of said main penetrator.
