Abstract
The invention relates to means for reducing the spread of shots in a weapon system in which the shots are fired from the weapon in a ballistic trajectory from a launching device towards a target. It comprises means for measuring the position of the target, means for measuring the muzzle velocity of the ammunition unit, and, in one embodiment, also means for measuring the actual trajectory parameters of the ammunition unit (shell, projectile or the like), for instance the reduction of velocity in a specific trajectory distance. In response to these values the impact point is predicted. A braking command is transmitted to the ammunition unit via a radio line in response to the difference between the actual position of the target and the predicted impact point for braking the velocity of the ammunition unit in order to improve the hit probability. The braking means preferably comprises a plurality of braking flaps distributed about the periphery of the ammunition unit. Normally the braking flaps are retracted but they can be activated into a protruding position by an actuating device. Alternatively the desired braking effect can be obtained by separating different parts of the nose se…
