Abstract: The MLRS1 artillery rockets (11) which are stored in the depots of the consumer can enjoy in a technologically non-critical fashion an increase in performance in the sense of a substantially improved degree of delivery precision, insofar as the ogival head (13) is temporarily cut off so that it is possible to fit into same and thus into the foremost region of the original payload space (15), which is behind the fuse (12), in a position of surrounding the pyrotechnic delivery ejection system, an annular assembly frame (21) for a transverse thrust unit (23) with reaction elements (25), which blow out radially around the rocket, which, in dependence on position, can be individually triggered by a navigation satellite-supported course correction unit (20) which is also fitted there.

Abstract: The novel compounds are chiral esters of .alpha.-substituted phenylalkanoic acids and mesogenic hydroxy compounds, the symbols in the general formula (I) ##STR1## being defined as follows: MO=molecular radical of a mesogenic hydroxy compound MOH after removal of one H, the radical MO being expressed by the general formula (II)R.sup.2 --(A.sup.1).sub.n1 --(B--).sub.n2 (A.sup.2).sub.n3 --O (II)whereR.sup.2 =straight-chain or branched (C.sub.1 -C.sub.12)-alkyl, it being possible for one or two non-adjacent CH.sub.2 groups to be replaced by O and/or S atoms, or, if n1=1, also F, Cl, Br, CN or CF.sub.3,A.sup.1, A.sup.2 =independently of one another 1,4-phenylene, diazine-2,5-diyl, diazine-3,6-diyl, 1,4-cyclohexylene, 1,3-dioxane-2,5-diyl, 1,3-dithiane-2,5-diyl or 1,4-bicyclo(2,2,2)octylene, it being possible for these groups also to be at least monosubstituted by F, Cl, Br, CN, CF.sub.3 and/or (C.sub.1 -C.sub.12)-alkyl (one or two non-adjacent CH.sub.
