This book is the first account of naval intelligence activities during the period that began in the final months of World War II and ended in 1991 with the collapse of the Soviet Union. The book is based on interviews with intelligence officers of the Soviet Navy and Western navies, sources, important publications from Western archives and the latest historical research, as well as stunning revelations from both sides of the Iron Curtain and chilling episodes of numerous secret battles that fought between the two most powerful states on the planet. The colorful and dynamic narrative tells how the German inventor became the “father” of cruise missiles for the American Navy; how a Soviet GRU naval officer worked with a French Air Force general who supplied the Kremlin with necessary information before, during and after the Cuban Missile Crisis; about the Gulf of Tonkin incident in 1964; about the disasters of the American reconnaissance ships "Liberty" and "Pueblo" and the metamorphosis that reconnaissance ships underwent after that, and about much more.
