1. A GNC device for use with a projectile, comprising: a rotating GNC portion and a non-rotating GNC portion, the rotating GNC portion being fixedly coupled to a projectile body, the non-rotating GNC portion decoupled from the projectile body, at least one bearing being interposed between the rotati
1. A GNC device for use with a projectile, comprising: a rotating GNC portion and a non-rotating GNC portion, the rotating GNC portion being fixedly coupled to a projectile body, the non-rotating GNC portion decoupled from the projectile body, at least one bearing being interposed between the rotating GNC portion and the non-rotating GNC portion, the at least one bearing permitting the rotating GNC portion to rotate with respect to the non-rotating GNC portion, and a first pair of stops, each of the respective stops of the pair of stops defining a gap between the rotating GNC portion and the non-rotating GNC portion during unloaded conditions. 2. The GNC device of claim 1, wherein a longitudinal force acting in a first direction closes a first of the first pair of stops. 3. The GNC device of claim 2, wherein the longitudinal force acting in a second opposed direction closes the second of the first pair of stops. 4. The GNC device of claim 3, wherein the respective closing of either of the stops of the first pair of stops acts to prevent the imposition of the respective longitudinal forces on the at least one bearing. 5. The GNC device of claim 3, wherein the respective closing of either of the stops of the first pair of stops acts to cause the rotating GNC portion and the non-rotating GNC portion to rotate in engaged unison. 6. The GNC device of claim 5, including a second pair of stops, each of the respective stops of the second pair of stops defining a gap between the rotating GNC portion and the non-rotating GNC portion during unloaded conditions. 7. The GNC device of claim 6, wherein a transverse force acts to close the second pair of stops. 8. The GNC device of claim 7, wherein the respective closing of the second pair of stops acts to prevent the imposition of the transverse force on the at least one bearing. 9. The GNC device of claim 6, wherein the respective closing of the second pair of stops acts to cause the rotating GNC portion and the non-rotating GNC portion to rotate in engaged unison. 10. A GNC device for use with a projectile, comprising: a rotating GNC portion and a non-rotating GNC portion, the rotating GNC portion being fixedly coupled to a projectile body, the non-rotating GNC portion decoupled from the projectile body, at least one bearing means being interposed between the rotating GNC portion and the non-rotating GNC portion, the at least one bearing means for permitting the rotating GNC portion to rotate with respect to the non-rotating GNC portion, and a first pair of stop means, each of the respective stop means of the pair of stop means for defining a gap between the rotating GNC portion and a non-rotating GNC portion during unloaded conditions. 11. The GNC device of claim 10, wherein a longitudinal force acts in a first direction acting to close a first of the first pair of stop means. 12. The GNC device of claim 11, wherein longitudinal force acts in a second opposed direction to close the second of the first pair of stop means. 13. The GNC device of claim 12, wherein the respective closing of either of the stop means of the first pair of stop means is for acting to prevent the imposition of the respective longitudinal forces on the at least one bearing. 14. The GNC device of claim 13, wherein the respective closing of either of the stop means of the first pair of stop means is for acting to cause the rotating GNC portion and the non-rotating GNC portion to rotate in engaged unison. 15. The GNC device of claim 14, including a second pair of stop means, each of the respective stop means of the second pair of stop means for defining a gap between the rotating GNC portion and the non-rotating GNC portion during unloaded conditions. 16. The GNC device of claim 15, wherein a transverse force acts to close the second pair of stop means. 17. The GNC device of claim 16, wherein the respective closing of the second pair of stop means is for acting to prevent the imposition of the transverse force on the at least one bearing. 18. The GNC device of claim 16, wherein the respective closing of the second pair of stop means is for acting to cause the rotating GNC portion and the non-rotating GNC portion to rotate in engaged unison. 19. In a GNC device for use with a projectile, a method comprising: interposing at least one bearing between a rotating GNC portion and a non-rotating GNC portion , and a first pair of stop means, each of the respective stop means of the pair of stop means for defining a gap between the rotating GNC portion and a non-rotating GNC portion during unloaded conditions, and permitting the rotating GNC portion to rotate with respect to the non-rotating GNC portion by means of the at least one bearing.
