The book delves into the engineering challenges and innovations required to construct these underground facilities, often in geologically complex environments. It examines how the design and purpose of subterranean bases have shifted over time, emphasizing their role in command and control, intelligence gathering, and strategic communication.
Drawing from declassified documents and expert interviews, the book offers a multidisciplinary approach, integrating insights from engineering, geology, military science, and political science. Beginning with the historical precedents for underground fortifications, the book progresses through the design and construction phases, using examples like Cheyenne Mountain to illustrate engineering innovations and logistical hurdles. It then analyzes operational aspects and assesses the future relevance of these installations in the face of emerging threats, connecting to broader fields like civil engineering and architectural innovation. This approach provides a comprehensive understanding of these hidden dimensions of modern warfare.
