Abstract: In a guided missile, a target direction detecting unit finds, from target information obtained at a target acquisition unit, a direction of the target in terms of a roll-, a pitch- and a yaw-axis of a missile fuselage, rotation amount computing units computer amounts of rotation around the roll-, pitch- and yaw-axis to allow the missile fuselage to be directed at a predictive missile/target point, and steering control units impart the amounts of rotation to the missile fuselage. Antennas for a proximity fuse are arranged around a circumferential surface side of the missile fuselage and radiate beams in mutually different directions with at least one of these antennas radiating a different beam at a forward-tilt angle other than the remaining ones. A beam forward-tilt angle selecting unit selects a proper forward-tilt angle beam from flight information of the missile and target.
