An extensive, detailed and yet compact guide to the history of the German submarine weapon 1935-1945. The submarines U-1 to U-24 are presented here in detail and conscientiously: Type, designation, technical data, length, propulsion system, armament, crew and supplementary remarks. It is also possible to find out when which ship sank where, which crew it had and even whether there were Oak Leaf or Knight's Cross holders among the crew. This is a rich resource for model builders, naval scientists and historians. A very interesting book with many fascinating, mostly previously unpublished photographs from private archives and museums, colour profiles and crests.
