Rings of Supersonic Steel

Mark L. Morgan's "Rings of Supersonic Steel: Air Defenses of the United States Army 1950-1979, An Introductory History and Site Guide" stands as one of the most thorough references available on a subject that has largely faded from public memory: the extensive network of Nike missile installations that once encircled American cities during the Cold War. This book, co-authored with Mark Berhow in its more widely known edition, brings together decades of research into a single volume that serves both as a historical narrative and a practical guide to physical sites that remain scattered across the country.

The premise of the book is straightforward but significant. Between the early 1950s and the late 1970s, the United States Army constructed hundreds of surface-to-air missile sites, first armed with Nike Ajax missiles and later upgraded to the more powerful Nike Hercules systems, to defend major metropolitan areas and strategic military installations against the perceived threat of Soviet bomber attack. These installations, often built in pairs consisting of a launcher area and a separate radar control site, formed rings around cities from New York to Los Angeles, Chicago to Seattle. Morgan's work documents this infrastructure with remarkable specificity, providing site designations, locations, unit histories, and operational timelines that would otherwise require extensive archival research to compile.

What distinguishes this book from a purely academic treatment is its dual function as both history and field guide. The introductory chapters lay out the strategic context that led to the Nike program's creation, tracing the evolution of American air defense doctrine as bomber threats gave way to intercontinental ballistic missiles, which ultimately rendered the entire system obsolete by the late 1970s. Readers unfamiliar with Cold War defense infrastructure will find this section accessible, as Morgan avoids excessive technical jargon while still conveying the seriousness with which military planners approached the threat of nuclear attack from the air.

The bulk of the book, however, consists of detailed site listings organized by defense area. Each entry typically includes information about the specific location, the units that manned the site, the type of missile deployed, and notes on the site's current status, whether demolished, repurposed, or still visible in some form. This level of detail makes the book invaluable for military historians, preservationists, and hobbyists interested in locating remnants of Cold War infrastructure. Many of these sites have been converted into parks, private property, or simply abandoned, and Morgan's documentation provides a crucial record before further development erases what remains.

The book's strength lies in its comprehensiveness rather than its narrative flair. This is not a dramatic account filled with tension or personal anecdotes from soldiers who staffed these sites. Instead, it reads as a methodical catalog, which is precisely what makes it useful as a reference work. Those seeking a page-turning history of Cold War paranoia or espionage will need to look elsewhere. Those interested in the physical and organizational reality of American continental air defense, however, will find exactly what they need.

Some readers may find the site-guide format dense, particularly if approaching the book without prior interest in military installations or defense history. The prose in the informational sections is functional rather than literary, prioritizing accuracy over readability. This is a reasonable tradeoff given the book's purpose, but it does mean the work rewards patience and genuine curiosity more than casual reading.

Photographs and maps, where included, add considerable value, helping readers visualize sites that have often changed dramatically since their military decommissioning. The inclusion of unit lineage and operational dates also allows researchers to trace connections between specific installations and the broader Army Air Defense Command structure.

Overall, this book fills a specific and important niche. It preserves institutional knowledge about a defense system that shaped the landscape of American cities for nearly three decades, yet remains largely unknown to the general public. For anyone researching Cold War history, local military heritage, or simply curious about the concrete remnants sometimes found in suburban parks and hillsides, Morgan's work offers a dependable and detailed starting point.
