A cross-section of a missile 1 with the missile attachment 2. The missile attachment consists of a cylindrical tube 3 which encircles part of the missile 1, and a protruding section 4 with a concave forward facing surface area 5. Shown also is a friction inducing movable component in the form of a lever 11 pivotly attached to the missile by a bracket 12, such that the lever 11 can be pivotly moved an actuating mechanism which is in the form of an electric motor 13 using a rotor arm 14. When the lever is pivoted by the electric motor 13, using the rotor arm 14, a part of the lever is pressed through a hole 15 in the missile 1 so that the part of the lever that is pressed through the hole can reach the cylindrical tube. As the rotor arm 14 presses harder against the lever, the lever is pressed harder against the cylindrical tube. With the friction that occurs between the lever and the cylindrical tube, the rotation of the cylindrical tube relative to the missile can be controlled, so that the spiralling motion of the missile can be controlled. A computer 16 controls the action of the electric motor 13, and a battery 17 provides electrical power for the computer and the electrical motor.
