A fin assembly for a projectile, the fin assembly including: a plurality of fin elements, each comprising a sheet of flexible material, attachment means for attaching an edge region of said fin element to said projectile, a relatively rigid trailing edge member for having one end thereof mounted on said projectile for allowing movement of said edge member with respect to said projectile, each of said fin elements being movable between a stowed position adjacent the projectile in which the fin element is in a generally collapsed state, and an extended position in which the fin element is supported in a generally planar state; and aerodynamically driven deployment means comprising an element of flexible sheet material extending between trailing edge members of adjacent fin elements.
