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.

A nose unit for a penetrator projectile having a high ratio of length to diameter and constructed to be at least transitionally variable in shape to improve the separation of discardable sabot segments after emerging from the barrel of a weapon, wherein the nose unit is axially movably mounted in a central axial bore of said penetrator projectile; said bore receiving said nose unit which has a frusto-conical front end, formed in such way, that in the initial position prior to firing of the projectile, the front end of said nose unit is in a retracted position in said bore; said nose unit being moved forward out of said bore during firing acceleration such that said nose unit, on leaving said barrel projects forwardly in said bore of said projectile, the nose unit having a second central axial through-bore, said bore of the projectile forming a guide for said nose; said nose unit being slidably mounted in said first bore so as to form a piston fitting the first bore; the rear end surface of said nose unit abuts in the initial position against an annular confronting surface of said first bore, a blind hole is disposed at the rear of the first central axial bore, after the projectile has left the barrel of the weapon airflow through said second central axial through bore of said nose unit causes pressure to build up in the blind hole to displace the nose unit in the direction of flight of the projectile.
