This comprehensive reference book traces the hundred-year history of the German submarine from its modest beginnings in 1904, through the huge fleets of the two World Wars, to the commercially successful designs of the present day. Every class of U-boat is given a detailed data sheet, including individual fates, and the book is illustrated throughout with historic photographs and plans.
