Project history

The Oldenburg, designed between 1879 and 1881, was considered to be of little fighting value by the time she was completed. She had originally been intended as a ship of the Sachsen class, but funds for this proved insufficient. Her main armament was mounted in a central battery, six guns on the main deck, two firing on the broadside, and the others set in embrasures to give an approach to end-on fire fore and aft. The remaining two 240mm guns were placed above the battery an the upper deck, firing on the broadside.

Ship protection

Compound steel-iron armour was used. Main belt was consisted of upper strip (300mm in the citadel and 200mm outside citadel) and lower strip (250mm in the citadel and 180mm outside), both were backed by 250(citadel)-300mm (ship ends) wood. Casemate was protected by 200 (amidships) - 150mm (to the ends of casemate) armour backed by wood (200mm amidships and 250mm to the ends). Armour deck was 30mm thick. Main CT had 50mm sides and 25mm roof, aft CT had 15mm sides and 12mm roof.
