A projectile having a fin deployment system disposed about its circumference. The fins are initially contained by a fin cover that is removed by aerodynamic force. The fins are then rotated around a rotational axis parallel to and offset from the central axial axis of the projectile body by the centrifugal forces created by the rotation of the projectile as the projectile passes through a barrel of a gun system or tube launcher. The fin deployment system can also have locking systems that lock the fins in the deployed position and prevent the fins from rotating back into the retracted position after deployment.

Fin deployment system

A GNC device for use with a projectile, includes a rotating GNC portion and a non-rotating GNC portion, the rotating GNC portion being fixedly coupled to a projectile body, at least one bearing being interposed between the rotating GNC portion and a non-rotating GNC portion, the at least one bearing permitting the rotating GNC portion to rotate with respect to the non-rotating GNC portion. In a GNC device for use with a projectile, a method is further included.
