An improved method and apparatus for aiming a gun at a target moving along a non-linear path is disclosed which relies upon the discovery that at any given moment in a non-linear path, a target is traversing an arc of a circle. Methods for calculating offsets for aiming a gun at a point further along on the arc of the circle in accordance with the determined time of flight of the projectile are disclosed.
