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: A guided missile which can be fired as a mortar projectile with armour-piercing hollow-charge warhead behind a seeking head for autonomous or semi-autonomous final phase guidance is to be capable of use for universal use from the same mortar weapon selectively against hard-armoured targets and against concreted protective constructions. For that purpose provided in front of the blast-forming main hollow charge is a boring hollow charge which is also blast-forming but slower and of higher mass and which, in the event of impact against a target, clears in a region-wise manner the reactive additional armouring of an armoured vehicle or penetrates the concrete wall of a protection arrangement. Upon impact against the target, a sub-calibre post-firing fragmentation explosive charge is released due to inertia from its holder in order to detonate after passing through the hole in the concrete wall therebehind or in the event of impact against a hard target to produce secondary effects against sensor elements.

Abstract: An arrangement for the unlatching and extension of the stabilizing fins or control surfaces of a projectile, including a power element which is effective in the longitudinal direction of the projectile for pressing a follower against camming or runoff edges located proximate hinged connections at the fin footings, after a latching for the stabilizing fin in the region of their end surfaces has been released. The power element causes a latching crown or ring to be raised away from the end surfaces of the stabilizing fins opposite the force of a spring through the longitudinal movement of a connecting or pusher rod prior to the pusher rod engaging behind the follower and then pressing against the runoff or camming edges.
