The 'Ostpreussen' was a concurrent design to the 'Helgoland'-class dreadnoughts. But her lesser firepower with only four turrets gave her the nicname of 'the cruiser who wants to play battleship'. She was a sole ship, no other ships of her design were laid up. The mockers got silenced after the battle at Skagerrak strait, where she took minor damage only but was able to hit HMS Marlborough hard. The positioning of all main turrets on centerline was first repeated with the Koenig-class, all predecessors were equipped with wing turrets.
