This book, first published in 1991, provides a major analysis of the prelude to the US’s Cold War maritime strategy, showing how NATO’s maritime forces were organised in the period. It examines how the United States Navy and allied navies, particularly the Royal Navy, were incorporated into the Alliance’s nuclear and conventional deterrent forces. It looks at the structure of the main naval commands, the growth of Soviet maritime forces and the impact of the flexible response strategy on NATO’s naval posture in the 1970s. Drawing upon many declassified documents, this account fills an important gap in postwar literature on American seapower and its relation to European security. It also addresses important aspects of NATO strategy and organisation.
