Book excerpt: In this book, Michael Glynn explores a journey through the history of more than one hundred years of aerial sub hunting. From the Great War, through the Battle of the Atlantic in World War II and on to the secret confrontations of the Cold War, the reader will witness the parallel evolution of both aircraft and submarine as each side tries to gain supremacy over the other. In so doing, Glynn distills complicated oceanography, operations analysis, and technical theory into easily digested concepts, helping the reader understand how complex weapons and sensors function. By reviewing the steps of a submarine hunting flight, the reader can quickly understand how theory and practice fit together and how aviators set out to achieve their goal of detecting their submarine targets. Airborne Anti-Submarine Warfare is a thrilling read for those seeking a glimpse into an arcane and high-stakes world.
