An essential new account of how anti-submarine warfare is conducted, with a focus on both historic and present-day operations. This new book shows how until 1944 U-boats operated as submersible torpedo craft which relied heavily on the surface for movement and charging their batteries. This pattern was repeated in WWII until Allied anti-submarine countermeasures had forced the Germans to modify their existing U-boats with the schnorkel. Countermeasures along also pushed the development of high-speed U-boats capable of continuously submerged operations. This study shows how these improved submarines became benchmark of the post-war Russian submarine challenge. Royal Navy doctrine was developed by professional anti-submarine officers, and based on the well-tried combination of defensive and offensive anti-submarine measures that had stood the press of time since 1917, notwithstanding considerable technological change. This consistent and holistic view of anti-submarine warfare has not been understood by most of the subsequent historians of these anti-submarine campaigns, and this book provides an essential and new insight into how Cold War, and indeed modern, anti-submarine warfare is conducted.

An overview of offense-defense theory, which argues that the relative ease of offense and defense varies in international politics. Offense-defense theory argues that the relative ease of offense and defense varies in international politics. When the offense has the advantage, military conquest becomes easier and war is more likely; the opposite is true when the defense has the advantage. The balance between offense and defense depends on geography, technology, and other factors. This theory, and the body of related theories, has generated much debate and research over the past twenty-five years.This book presents a comprehensive overview of offense-defense theory. It includes contending views on the theory and some of the most recent attempts to refine and test it.

Environmental information is important for successful planning and execution of naval operations. A thorough understanding of environmental variability greatly increases the likelihood of mission success. To ensure that naval forces have the most up-to-date capabilities, the Office of Naval Research (ONR) has an extensive environmental research program. This research, to be of greatest use to the warfighter, needs to be directed towards assisting and solving battlefield problems. To increase research community understanding of the operational demands placed on naval operators and to facilitate discussion between these two groups, the National Research Council's (NRC) Ocean Studies Board (OSB), working with ONR and the Office of the Oceanographer of the Navy, convened five previous symposia on tactical oceanography. Oceanography and Mine Warfare examines the following issues: (1) how environmental data are used in current mine warfare doctrine, (2) current procedures for in situ collection of data, (3) the present capabilities of the Navy's oceanographic community to provide supporting information for mine warfare operations, and (4) the ability of oceanographic research and technology developments to enhance current mine warfare capabilities. This report primarily concentrates on the importance of oceanographic data for mine countermeasures.
