PURPOSE: To improve response of a body, to simultaneously steer steering blades and to improve performance by providing actuators of main wings, front wings and rear wings to be operated upon reception of signals of main wing, front wing and rear wing moving mechanisms and a controller.

CONSTITUTION: A guided missile 1 has two types of steering wings of front wings 2 at the front of the wings 3 and rear wings 4 at the rear of the wings 3, and the actuators of the wings are simultaneously operated to be steered upon reception of a control signal from one controller 5. The point of application of a body is moved forward by the forward movements of the wings 2, 3, 4, a distance of the center of gravity and the point of application can be shortened upon combustion of a socket motor to improve response of the body. Since the two types of steering wings are simultaneously steered by the one controller 5, fast response of the front wing steering system and high trim angle of the rear wing steering system are obtained to improve the performance of a missile.
