The 2015 Swedish defence bill 2016-2020 underscores that the primary concern for this period is to increase the operative capability of the military units and to ascertain the aggregate capability of the total national defence. Through experience we know that logistics not seldom sets a limit to the operative capability and that the new guiding principles express demands for security of supply in peace as well as in increased military readiness. The need for security of supply for 'military stock materiel3' and how this shall be created is presently not apparent in peace and most of all not under increased readiness, which could have consequences for the military units' operative capability, now and in times to come. In this report a military supply chain for military stock materiel is generically described and analyzed and the principal challenges that the defence authorities face in their assignment to create a sufficient degree of security of supply in peace and increased readiness are discussed. The principal challenges that need to be addressed in order to reach the strategic objectives in parts concern the strategic planning tasks in the transformation of the supply chain, and in parts concern acquisition, lead times and stock levels of the materiel. Interviews, analysis of official documents and site visits point to a high level of competence in the defence authorities concerning security of supply. The steering must however support the continuous, contributive efforts towards reaching a sufficient security of supply. Recommendations are presented regarding specific actions and recommendations in order to attain cost-efficient security of supply through risk management and category management for military stock materiel.
