Abstract: A nose unit for a discarding sabot penetrator having a bolt in a bore of the pointed nose which is temporarily displaced on firing due to acceleration and against a restoring spring. This produces a circular edge and a break in the contour of the nose to define a limit surface between a zone of supersonic airflow and a zone of subsonic airflow, at least during the separation of the sabot segments. This facilitates the uniformed detachment of the segments.

Abstract: A composite armor-piercing subcaliber projectile has a front projectile part generally centered on an axis and having a rearwardly extending cylindrical sleeve of predetermined outer diameter and also generally centered on the axis and a rear projectile part centered on the axis and having a cylindrical outer surface substantially of the outer diameter and having a small-diameter forwardly extending projection fitting complementarily within the sleeve. An explosive charge between the front and rear parts can be detonated, as for example by a proximity fuse, to push the front part axially forward away from the rear part. The front part and sleeve can be unitary. In addition the front part can be tubular and centered on the axis.

Abstract: A projectile arrangement for a gun barrel weapon having a plurality of sub-caliber projectiles which are mounted on a common sabot which is composed of a plurality of segments. These projectiles are designed for a sequential flight one behind the other at predetermined distances and along a common flight path and are joined to each other by means of a wire. The leading projectile deactivates a detonating charge upon impacting on a target region of a "actively armored" target, so that the next following projectiles can become target-effective without being disturbed.

Abstract: A subcaliber projectile assembly especially for attack against active armor has an enabling projectile disposed axially ahead of a main projectile and in line and in end-to-end relationship therewith in a common sabot. The fin structures of the two projectiles are designed to increase the resistance of the main projectile so that it is retarded relative to the enabling projectile and strikes the target only after the enabling projectile has depleted at least one level of defense along the line of attack.
