A multiplicity of launching tubes for nonguided projectiles, clustered about a central axis, are divided into several groups of 2n tubes each, the muzzles of each group of tubes being trained in directions diverging from one another in at least one dimension at a small angle designed to spread the projectiles of each group over a predetermined segment of an area centered on the main axis. The tubes of each group are subdivided into pairs whose muzzles are distributed symmetrically about the main axis and which may be fired simultaneously to provide a balanced recoil. A computer determines from the output of a tracking radar the location of a region of uncertainty, centered on the calculated position of a target to be destroyed, and selects the group or groups whose segments cover that region whereupon the tubes of the selected group or groups are fired simultaneously or in rapid succession. The entire array may undergo a sweep motion in one dimension (e.g. azimuth) while the tubes, with axes diverging in the other dimension (elevation), fire repetitively to cover the assigned sector; this sweep motion is superimposed upon the computer-controlled tracking motion designed to keep the main axis of the array in line with the presumed target position as calculated for the moment of impact. |
