Patent ID: 7267298

Claim:
A ballistically fireable spin-stabilized artillery ammunition article, which in plotted hits thereof evinces a longitudinal and transverse scattering; a fuze which is roll-decoupled from a body of the ammunition at a tapered front part of the ammunition body; and two control shafts on said front part of the ammunition body oriented radially of a spin axis mounting two canard surfaces, which are directed oppositely away from said spin axis and which are adjustable about a single axis, said canard surfaces being of full caliber and non-retractable and responsive to rotation of their control shafts and being adjustable in both directions relative to a neutral setting, so as to be in accordance with a momentary roll position of the canard surfaces in space and in accordance with the actual setting of the surfaces through a controlled pitch movement, to influence the longitudinal scattering or through a controlled yaw movement influence the transverse scattering.
