British Cold War government bunkers were built to preserve state authority after a nuclear attack, but the catastrophe they anticipated never occurred. This article argues that they are infrastructures of suspended crisis: material systems organised around an event that did not arrive and therefore shaped by a temporality of the not yet. Drawing on Derrida’s hauntology, it reads the bunker as a site where an expected disaster remains active as a ghost, continuing to organise present perception and interpretation. These sites do not store memory of an actual catastrophe. Rather, they preserve the afterlife of institutional rehearsal, including plans, routines, and spatial arrangements designed for an imagined aftermath. Bringing futures studies into dialogue with memory studies, the article shows how bunkers can hold latent cultural memory and trauma-like orientations without an originating disaster. The argument is based on fieldwork at Kelvedon Hatch and Barnton Quarry, supported by 3D LiDAR scanning, point cloud processing, and visualisation. The resulting uncertainty images are treated not as neutral records or scientific revelation, but as practice-led critical media. Their continuity, occlusion, instability, partial viewpoints, and micro-temporality of capture register gaps in knowledge and the atmosphere of anticipatory governance. At a moment of renewed nuclear anxiety and resilience planning, Cold War bunkers return again as templates for imagining future crisis in public culture today. The article shows how collective future thinking can be organised around what never happened, and offers a practice-based method for demonstrating how unrealised threats still act in the present.
