Abstract: Disclosed is a method and an apparatus for accelerating and shooting a flying body at superhigh speed, consisting of a capacitor in which a high electric charge can be stored; a primary coil connected to the capacitor via a switching means; a conductive cylindrical liner disposed in the primary coil; an opening defined on a cylindrical wall of the cylindrical liner; and a flying body interposed in the opening and assuming electrical continuity with the liner; wherein a high electric charge stored in the capacitor is momentarily applied to the primary coil so as to compress abruptly the cylindrical liner radially inward and to shoot the flying body interposed in the opening toward the axis of the liner.
