    An efficient estimation of the aerodynamic characteristics for a missile configuration is required in the preliminary stage of a missile design. In this study, a semi-empirical code based on Missile Datcom97 was utilized for this purpose. In order to check the accuracy and reliability of the code several test cases have been considered: subsonic flow with a high angle of attack, supersonic flow with moderate and high angle of attack. It turned out that the code provides prediction in qualitative agreement with the experimental data and results by other works. Finally, the code was applied to a more complicated missile configuration with canard and freely spinning WAF(Wrap-Around-Fin). An emphasis was placed on the analysis of the characteristics of the canard hinge moment, rolling moment and damping of the tail fin.
