In an era of escalating geopolitical tensions and hybrid threats, logistics has emerged as a decisive pillar of national crisis preparedness. This paper examines the role of logistics within Sweden’s total defence framework, situating it within the broader literature on critical infrastructure resilience and drawing comparative lessons from Ukraine’s wartime experience. Using a qualitative case study design that combines critical event analysis with comparative institutional analysis, the study scrutinises key dimensions of Swedish logistics, including vehicle and driver availability, fuel distribution and stockpiling, infrastructure robustness, and civil–military coordination. The findings reveal three interrelated weaknesses in Sweden’s logistical preparedness: fragmented planning structures, personnel and fleet vulnerabilities, and inadequate strategic reserves. These weaknesses risk turning logistics into a single point of failure during prolonged crises or high-intensity conflict. Insights from Ukraine underscore that logistics is not merely a support function but a strategic capability: sustained disruption can paralyse both military manoeuvres and civilian survival. The paper argues that Sweden must adopt a preparedness-oriented logistics strategy, encompassing expanded stockpiling, stronger legal frameworks for civilian resource mobilisation, investments in dual-use and redundant infrastructure, and deeper civil–military integration. By reframing logistics as a strategic enabler of deterrence and resilience, the study contributes to understanding how modern states can secure societal continuity under conditions of systemic stress.
