Phalanx CIWS Penetrator Rounds

Abstract : The central purpose of this program was to develop forging know-how on U-2% Mo specifically related to the Phalanx penetrator. The forging process studied was one concerned with producing near net shape penetrator blanks which would reduce raw material requirements and reduce machining costs. The factors which affect the forging process were studied. The results of this work showed that net shape penetrators of 90% of the volume of the penetrator could be forged, thereby reducing material requirements by 17% and eliminating a major portion of the precision machining required. U-2% Mo was found to be an easily forged material, relatively insensitive to forging temperature in the range of 700-1100F.
