Abstract

The invention concerns a missile body having a first flight guide and stabilization means mounted on the missile body and a second guide and stabilization means mounted on the missile body in front of the first guide and stabilization means with respect to the direction of flight. The second guide and stabilization means comprise a plurality of wings which are folded inwardly (collapsed inwardly, pivoted inwardly) into the missile body when in their inoperative position. These wings can be pivoted or slid outwardly when in their operative position by means of a collapsed expandable body which is expanded by means of pressurized gas. The pressurized gas is stored in a pressurized gas cylinder mounted within the missile body. The expandable body expands in a radial direction and thereby exerts a force on the wings which causes them to either pivot about a rotatable axis or to move in a radial direction outwardly of the missile body.
