Underground Command Centers (class of continuity facilities)

Concrete ribs and steel blast doors descend into a low-thrum underworld of generators and encrypted radios. Fluorescent light washes sterile consoles where continuity plans run like clockwork; narrow corridors funnel movement through checkpoint scanners and keyed access, limiting passage to a filtered few. These subterranean government continuity facilities promise operational survival in a nuclear attack and function as alternate evacuation destinations to Air Force One. The space smells of metal and recycled air, hums with clipped radio cadence, and carries a moral charge—safety for the designated few, abandonment for those left behind—sharp enough to reshape loyalties and decisions.
