"The release of this book creates high expectations. It is subject matter with a clear gap in the historical record and now a distinguished naval expert attempts to fill the void. . . . Readers will discover that the high expectations are well met."—D. Colt Denfeld, Journal of America's Military Past
"Norman Polmar and Lee Mathers' new book is the first comprehensive history of spy ships, and the authors should be lauded not only for closing a relevant desideratum in naval and maritime history, but also for collecting a trove of sources that allowed them to reconstruct the operational history of spy ships on both sides of the major conflicts of the 20th century—and, most important, during the Cold War."—Ingo Heidbrink, Proceedings
"An interesting and valuable addition to the intelligence officer's bookshelf."—Admiral Tom Brooks, ReadBook
“Spy Ships by Norman Polmar and Lee Mathers is another authoritative, comprehensive, and professional narrative that one expects from these authors. . . . Spy Ships fills a gap in our understanding of the importance of intelligence collection in naval operations. This book is a welcome edition in my reference library. BZ!”—Capt. John A. Rodgaard, U.S. Navy (Ret.), author of Tailships: Hunting Soviets with a Microphone
