ABSTRACT:
A weapon system is provided with a projectile incorporating improvements which reduce launching errors. In the preferred embodiment, the projectile is a rocket. The rocket is spin stabilized by gyroscopic force and a condition of nearly neutral aerodynamic stability is provided by the external rocket contour. In the preferred embodiment, the rocket is spin stabilized in flight by a forward fin ring and a rearward aerodynamic, flared skirt. The skirt includes a bearing ring structure which supports the rocket within a launcher vehicle or tube along the rearward portion of the rocket body. The fin ring constitutes a second projectile support during launch and is positioned along the forward portion of the projectile body. The projectile and its associated launcher vehicle are configured to eliminate tip off error. Both the bearing ring structure and fin ring are journaled to the projectile to permit rotation of the projectile body. The fin and bearing rings each have means integrally formed with them for spring loading the projectile within its launch vehicle prior to launch. Spring loading the projectile reduces mal aim launch errors during projectile firing.
