A spin-stabilized projectile has its course controlled by counter rotation of an internal mass about a longitudinal axis of the projectile. The internal mass may be a boom within a cavity of an external body of the projectile. The internal mass may be tiltable relative to the hull, and may be configured to counter rotate relative to the hull about the axis of the hull. The counter-rotation may keep the boom in a substantially same orientation relative to the (non-spinning) environment outside of the projectile. The positioning of the boom or other weight within the projectile thus may be used to steer the projectile, by providing an angle of attack to the projectile hull. A magnetic system may be used to counter rotate the boom or other weight. The projectile may have a laser guidance system to aid in steering the projectile toward a desired aim point. |
