Description: The influence of the anti-aircraft missile systems development prospect on the quality of operational commitment were considered. The main tasks during development (modernization) of the anti-aircraft missile systems and anti-aircraft guided missile were substantiated. The analysis of the methods of substantiating of anti-aircraft missile systems promising indicators nomenclature performed, identified their main merits and demerits. The purpose of the article is to develop a methodology for nomenclature characteristics substantiation that determine necessary requirements for promising anti-aircraft missile system under condition of supporting desired level of air targets casualties and the prospects for the development of aerial threats. The methodology of characteristics of nomenclature selection (specification) for synthesis of operational anti-aircraft missile systems characteristics are proposed and their designation of permissible variation. Such methodology is comprised of several methods: the method of substantiating sets of characteristics of anti-aircraft missile systems,which is based on assessment of aerial threats development process; an indicator of the anti-aircraft missile systems quality and features of building a mathematical model of such a system and recommendations on the designation of permissible variations in selected characteristics. The developed methodology allows to verify optimal selection of anti-aircraft missile parameters sets of systems and designation of their optimal selection under systems production of pre-screening when planning there development stages.
