GERMAN U—BOAT TYPE XXI

For a very long time people have taken it for granted the big, fast underwater boat of our age, nuclear powered and capable of staying under the water surface for weeks, even some months if necessary. And yet, scarcely more than four decades have passed since the time when the first nuclear-powered U-boat, the American Nautilus, was delivered and introduced a new era in naval warfare.

The publication features numerous photographs of the Type XXI being under construction. In general, the content is highly informative and will be liked by all people interested in submarines and naval history, particularly that of the war period. Subject boat was considered a true engineering marvel of that time.

The document is covering the whole history that eventually led to the development of the submarine, actual development of Type XXI submarine and quite short usage of the boat. In addition, there are some good quality engineering drawings of the boat, showing the general arrangement - they will present interest to the naval architects.
