These casting powders are intended to be blended with MIL-P-82698 casting powder to produce MIL-P-82701 casting powder for use in the manufacture of solid propellants for MK 12 boosters for Terrier and Standard (ER) surface to air missiles. Type II casting powder is also blended with JCM-1915 casting powder to produce POU-2 casting powder for use in the manufacture of solid propellant for MK 75 gas generators for Tomahawk missiles. Since the items for which these casting powders are to be used were designed for military ordnance, there is no commercial application.
