Nassau Class Battleship

First class of German dreadnoughts, the Nassau had a conservative design, despite the unusual arrangement of the diamond towers. The four fought at Jutland, with the Westfalen night standing out in the fighting against lighter British forces.

Description
The SMS Nassau was the first German Dreadnought and only slightly larger than the namesake of this category of vessel in the service of Royal Navy. The ship was wearing the latest developments in fire management account, where you could seek safe with larger guns with a greater range. Inside, the furnishings of wood material was increasingly replaced by sheet metal. Further design improvements in the details related to the systemic wall openings (cable channels, pipe systems) and emergency equipment (fire extinguisher, bilge and flood devices).

Arming
In addition to the now six 28-cm-Twin towers was retained, however, in contrast to the Royal Navy, a medium artillery of 15-inch guns at.

Plating
Due to the now high explosive power of torpedoes, a completely new kind of torpedo protection was developed, which was retained in all subsequent battleship classes. The thickness of the outer skin is only 12 mm. Behind it was a few meters wide empty space, the outer wall motion. In it was a part of the explosive energy is reduced. Behind a more normal wall, the Wall Gang Schott, was a second room, the inner Wall Gang, who served as coal or oil tank. This was further reduced energy, and ensured a uniform loading of the armored torpedo bulkhead. In the Nassau-class whose wall thickness was 20 mm. German battleships were given by this construction, a relatively large fuselage width.
