The apparatus of the invention allows flight vehicle and/or guided munition wings and control surfaces to be secured in a retracted and locked position prior to the launch by a control surface retainer. An electro-mechanical differential control system preferably releases the control surface retainer, extends the control surfaces, and servo controls the control surfaces subsequent to launch. The invention also provides a method for guiding a flight vehicle and/or guided munition by releasing the flight vehicle's and/or guided munition's control surface from a control surface retainer, extending the flight vehicle's and/or guided munition's wing/control surface assembly using a wing/control surface actuation system, and controlling the flight vehicle's and/or guided munition's control surfaces using a wing/control surface actuation system.
