This semiannual report provides results of tests conducted between 15 March 1985 and 31 August 1985 in support of the Aging and Surveillance program for the Minuteman II and III Stage II motors. The primary objectives of the program are to provide assurance that 1 the reliability of the presently deployed motor will not degrade within a projected replacement time of 17 years, and 2 the service life of the remanufactured motor will be equal to or greater than that of the presently deployed motor population. This volume also summarizes results of work completed in a number of special areas. Topics include initial testing of plug samples from a late production motor, dissection of a weathersealed motor, investigation of a propellant crack in a field-returned motor, investigation of early age-out motors, and evaluation of Stage II igniters for re-use in remanufactured motors. Keywords Propellant liner insulation systems LRSLALong Range Service Life Analysis Ignition delay Surface hardening Grain cracking.
