Guided artillery projectile and method

DETAILED DESCRIPTION According to the present invention, an artillery projectile is provided.
This artillery projectile includes an artillery shell, a plurality of fins mounted on the shell and movable relative thereto, each fin having actuating means for providing two dimensional steering of the projectile during projectile spinning, a control means for controlling the actuating means, and a guidance unit for providing information to the control means.
By using the guidance unit, initial errors introduced into the ballistic trajectory are calculated and corrected for during flight by manipulation of the fins or air deflectors, thus significantly improving overall projectile accuracy.
By using the unique actuators and fins/air deflectors synchronized with the spin of the projectile, spinning of the projectile does not interfere with the guidance.
