Abstract: A guided missile (12), in particular a projectile which can be fired through a propellent charge gas pressure, having rudder blades (18) which cross each other and which can be pivoted open to steer the missile (12). Each rudder blade (18) is mounted in a guide slot (22) which is closed at the front end by an end portion (26). Each end portion (26) has a spoiler end face (28). Each end portion (26) projects radially beyond the lateral longitudinal ribs (24). At its distal end portion (32) the associated rudder blade (18) is provided with laterally mutually opposite, narrow guide ribs (36) which project out of the rudder blade profile (34).

Abstract: To maintain control accuracy for the pivotable rudder blades (14), which lie in a combustion chamber, of a guided projectile (12) which can be fired by means of propellent charge, there is provide a mounting arrangement in which the trunnions (20) of the rudder blade holders (16) of the diametrally mutually opposite rudder blades (14) are torsionally stiffly rigidly connected through an associated coupling element (32) which is limitedly resilient in the radial direction of the guided projectile (12).
