Tail portion for fin-stabilized projectile

A tail portion for a fin-stabilized projectile, comprising at least two deployable fins, which are inclined, wherein the fins are arranged in at least two sections, which are arranged adjacent to one another in the axial direction, the fins being made of an elastic material, wherein each fin, prior to deployment, bears against a convex bearing surface, which extends within a cylindrical, circumscribing surface which is defined by the radius of the projectile, and wherein each bearing surface coincides with a part of the envelope surface of a notional cone, the apex of which is displaced from the centre axis of the projectile.
