SUB-CALIBRE ARMOUR-PIERCING PENETRATOR PROJECTILE

An improved subcaliber fin-stabilized penetrator projectile of an equal diameter along its whole cylindrical length which is made of a high density, ductile, heavy metal. The herein described penetrator has a steel ballistic hood coaxially mounted on the front end thereof and a plurality of frontal cores mounted one behind the other in an axial direction behind said ballistic hood, and a main penetrator core arranged behind the frontal cores. Detachably connected to said ballistic hood and extending from said hood to the frontal region of the main penetrator core is a cylindrical casing of heavy metal having a smooth external surface and an outer diameter which is equal to the outer diameter of the main penetrator core. The plurality of frontal cores are partially mounted in said cylindrical casing, and partially in said ballistic hood. The main penetrator core of the projectile has a cylindrical front end extension of smaller diameter with which the casing is rigidly attached, a transition piece and a frustoconical stem. The frontal cores are equal in diameter and have an axially centered bore and a recess, and have rear faces and front faces. The ballistic hood is detachably mounted and holds a plurality of said frontal cores together against one another inside said casing in a play-free manner, with the frontal cores inner surfaces snugly fitted against the outside surface of the stem, and said cores outer surfaces snugly fitted against the inner surface of the said casing.
