The effect of a uniaxially deformed aerogel on the orientation of the order parameter of {sup 3}He has been analyzed with the inclusion of correlations in the positions of the particles forming the aerogel. The minimum strain for the B phase in the uniaxially stretched aerogel that can lead to the orientation of the orbital part of the order parameter different from the bulk case has been estimated. The orientational effect has been estimated for the A-like phase in the uniaxially compressed aerogel has been estimated. It has been shown that the dependence of the orientational effect on correlations in the mutual locations of the aerogel particles is stronger than that of the superconducting transition temperature.
