A missile (10) and concepts for deploying the fins (14) thereof from a stored to a deployed position are disclosed. One device described has three main portions including: A first end portion (32) housing an initiator (22) that powers the device and a locking mechanism (26) that holds the fin at its stored and its locked position; a central portion (34) housing a driven piston (24) that rotates a positively connected fin (14) from the stored to the deployed position; and, a second end portion (36) housing a damping system that controls the rate of deployment of the fins.

An actuator for the deployment of a fin from a stored to a deployed position characterized by: a piston connected to said fin for deploying said fin from said stored to said deployed position, a damping means to which said piston is driven to control a rate of travel of said piston, and means for locking said piston and said fin thereby in said stored and in said deployed position, said means comprising first and second circumferential grooves disposed in space relation in a surface of said piston, a plurality of circumferentially spaced regularly flexible finger cooperating with said grooves to lock said piston in said stored and deployed positions, and means for fixing said fingers within said grooves and said stored and deployed positions, said means being responsive to pressure.
