An aiming drive (10), in particular for rapidly lining up the forked pivotal holder (10) of a launch receptacle (12) for fragmentation grenades defending against an attacking missile is to be designed, with precise simultaneous azimuth and elevation adjustment for particularly high level of dynamics of its aiming procedure in spite of a high weight of the launch receptacle (12) which is provided with the fragmentation grenades. For that purpose the setting motors (13,14) are disposed stationarily in a support structure (15) which is fixed with respect to the object, away from the pivotal holder (19) and protected from the effect of fragments, from which support structure they are rotatable connected to a carrier ring (18) for the pivotal holder (19). The carrier ring (18) is supported rotatably in the support structure (15). The elevation setting motor (13) which is also stationarily fitted into the support structure (15) coaxially with respect to the azimuthal axis (17) is provided with a translatorily acting drive output (23) which determines the elevation of the launch receptacle (12) by way of a support rod or bar (22) which extends substantially concentrically with respect to the azimuthal axis (17) and which is preferably rotatable about the latter.
