Guided munitions, also known as gliding missiles, are not stand alone systems; rather, they are converted from a dummy body with the help of guidance kits. Guided munitions are used in great number during military operations, unlike air-to-air or cruise missiles. Guided munitions can be classified in two main sub-categories. First group provides guidance and stability with use of strakes. These type of missiles used for relatively short ranges. Second group has wings instead of strakes and effective in larger ranges. Missiles in first subcategory may be converted to second group by changing their strakes with wings. For such a modification, both versions of that missile should be optimized together during the conceptual design phase. The main focus of this study is to obtain a conceptual design tool, by employing Genetic Algorithm with aerodynamic analysis, that optimizes a guided munition geometry which can be used as both versions, with strakes or wings, in terms of aerodynamics related objectives.
