Abstract

A highly effective and also inert active penetrator, an active projectile, an active airborne body or an active multipurpose projectile with a constructively adjustable or settable relationship between penetrating power and lateral effect. The end ballistic total effect which is obtained from the penetrating depth and covering the surface or stressing of the surface is initiated in an active case by means of a releasable arrangement or installation which is independent of the position of the active body.
