A family of ammunition is currently under development for the 8-in. major caliber lightweight gun (MCLWG) system. In this report the major alternatives for the propelling charge portion of the ammunition are examined. There are three relatively independent subassemblies in the propelling charge, namely the case, the primer, and the propelling charge itself. Cases can be fabricated of drawn steel, spiral wrapped steel, or other materials, the most promising of which is fiberglass. For primers the major options are to rework an existing inventory, to redesign the primers using the traditional technology, or to redesign the primer using more advanced technology. Propelling charge options address the chemical composition (NACO or M1A1) and physical characteristics (grain size). These alternatives are compared using the ideas of multidimensional utility analysis. In this analysis a first 'rough' cut was sufficient to enable the project manager to decide among the alternatives
