A guidance system for small spinning projectiles which is mechanically simple, has low power requirements, uses relatively unsophisticated electronics, and is capable of withstanding large gas pressures and accelerations. The system uses a one-piece fin assembly which is de-spun so that its guidance fins maintain a constant attitude with respect to the ground. The guidance fins and their hub can be nutated simultaneously and independently in two orthogonal planes by pivoting and translating a single control rod. The hub cooperates with the projectile body to reduce its base drag and thereby extend its range.

A guided spinning projectile, comprising: (a) a body; (b) a nutatable guidance fin assembly mounted on the aft end of said body; (c) control rod means for nutating said fin assembly; and (d) de-spinning means for rotating said fin assembly and control rod means at a rate equal to the spin of the projectile but in the opposite direction.
