The U-boat : The Evolution and Technical History of German Submarines

German U-boats came close to winning the First World War in 1917 and managed to repeat this performance in the Second World War. Yet, as Eberhard Rossler reveals, Germany was a late-comer to submarine construction and only embarked on the U-boat programme a few years before 1914. German designers were able to benefit from the hard-won experience of other navies. German industry could provide first class diesel engines and reliable electrical components, so it was not long before German yards were completing submarines equal if not superior to any in the world.
Technical history remains the poor relation of history. But the rise and fall of the U-boat arm in two world wars cannot be explained without understanding the 'hardware' of this unique conflict. This is the most comprehensive technical history of the U-boat fleet ever published: essential reading for anyone seeking to follow the most dramatic naval campaigns of the 20th century.
