PROBLEM TO BE SOLVED: To control the direction of the roll, pitch, and yaw of a missile by three actuators, and to make smooth actuation, simplify structure, or the like by combining a single swivel nozzle with pitch and yoke actuators with a thrust contorl nozzle for rolling. SOLUTION: In a missile 1, a rocket motor 3 is provided in the tail part of a drum 2, at the same time, a nozzle extension pipe 4 is provided on an axis line L from a tail end, and a single swivel nozzle 5 is provided at the tip. Also, pitch and yoke actuators 6 and 7 are provided at the outer periphery of the nozzle extension pipe 4, and the single swivel nozzle 5 is rotated in Y and Z directions. Furthermore, a housing 8 is provided at the base of the nozzle extension pipe 4, and two pairs of thrust control nozzles 9 and 10 for rolling are provided toward a direction orthogonally crossing the axis line L. Then, one of the thrust control nozzles 9 and 10 for rolling is opened, and at the same time the other is closed, thus changing the posture of the missile 1 to a rolling direction or the like.
