This regulation prescribes Department of Army policies, responsibilities, and procedures for managing and executing Army participation in the Defense Logistics Agency Weapon System Support Program administered by DLA. The DLA WSSP was established to enable the Services to identify to DLA those common consumable parts required to ensure adequate supply posture in support of organizational readiness objectives. The overall objective of the DLA WSSP is to enhance the readiness and sustainability of the military Services by providing the maximum practical level of support for DLA-managed items with weapon system application. The DLA WSSP enables DLA to develop a support strategy geared to the criticality of the weapon system end items as registered in the WSSP and the essentiality of its component parts. The DLA uses the WSSP to make personnel assignments, which initiate procurement actions, tailor business arrangements, and focus attention on national stock numbers degrading mission capability of the military Services’ critical systems.
