The problem of adding guidance, navigation and control capabiltities to spinning artillery projectiles is discussed from a fairly general perspective. Topics covered are the (limited) control authority of nose mounted control mechanisms and tradeoff conserning guidance and navigation. A brief review of relevant literature is also included and some topics for further study are suggested. The focus of the present study is to pinpoint underlying mechanisms and properties of the problem of adding guidance and control capabilities to spinning artillery projectiles using replacement fuzes. The purpose of the study is to facilitate decision making regarding further studies of guidance methods for artillery projectiles with replacement fuzes incorporating guidance and control capabilities.
