The tail section of a fin-stabilized, guided projectile having centrifugally deployed fins is disclosed. A fin retainer and release mechanism engages the projectile fins and holds the fins within the projectile diameter during normal stowage, handling and travel of the projectile down the gun tube. The fin retainer and release mechanism is designed to operate from the forces of gun launch to enable centrifugal deployment of the fins due to projectile rotation after the projectile leaves the gun tube.

A retainer and release mechanism for the centrifugally deployed fins on a fin-stabilized, gun-launched, guided projectile and operable from the forces of projectile launch comprising: a fin latch of generally cylindrical configuration provided with a plurality of circumferentially spaced notches adapted to engage similarly configured notches formed in the inner edges of the projectile fins thereby defining a plurality of inclined plane mating surfaces sloping inwardly in the forward direction toward the projectile axis, the mass of said fin latch being sufficient when acted upon by the set back or inertial forces of gun launch to hold the notches engaged and retain the fins within the projectile diameter against the urging of centrifugal forces on the fins due to projectile spin during travel down the gun tube, the mass being insufficient to retain the fins when the set back force ceases upon exit of the projectile from the gun tube whereby centrifugal forces still acting on the fins will cause the fin latch to slide forward along the inclined planes until the notches disengage and the fins are able to complete centrifugal deployment while the fin latch falls away; and means for retaining said fin latch in engagement with the fins during stowage and handling, said retaining means being designed to fail when set back forces are first applied during launch thereby releasing said fin latch.
