-Description |
Overview (U):(U) Analysis of the fielded Minuteman III (MM III) weapon system has predicted ageout of the Stage 1, 2, and 3 rocket motors. To support MM III weapon system requirements into the 21st century, a replacement/refurbishment of the MM III rocket motors including ordnance and integrating hardware is required. The PRP will: 1) provide technology insertion of changes to the existing motor/ordnance designs and processes to replace unavailable or environmentally unacceptable materials, components, and processes in addition to correcting known hardware problems; 2)provide updated flight constants for guidance and targeting software that is verified and validated for operational use; and 3) provide a remanufacture phase which will replace the existing MM III motors before they exceed their service lives. |
(U) The PRP extends the life, maintains the performance, and improves the reliability of the MM III operational force by replacing the solid propellant propulsion subsystems prior to ageout. The solid propulsion systems now in the force are projected to begin aging out in 2002 and must be replaced in order to support current force planning. The PRP will be executed in two phases: Technology Insertion (TI) and Remanufacture. During the TI phase, new materials and manufacturing processes will be qualified to replace unavailable or environmentally prohibited materials. Additionally, known failure modes and design weaknesses will be corrected by incrementally inserting and qualifying current rocket motor technologies. The PRP will reuse existing components to the greatest extent possible. Another goal of TI is to maintain the industrial base so that rocket motor production capability is available when needed for motor remanufacture. During remanufacture, the solid rocket motors will be remanufactured at a rate up to eight motors per month during the period FY 2000 through FY 2008.
(U) Software changes will be incorporated to account for material modifications incorporated during the TI phase. The missile control dynamics, mass properties, and propulsion characterization programs will be modified and validated to ensure a controlled flight.
(U) Ongoing Minuteman life extension efforts are required to extend the life of the MM III weapon system. The PRP will ensure the MM III rocket motors, ordnance, and integrating hardware are maintained at acceptable weapon system reliability thresholds through 2020.
(U) Programmed.
