SMS Preussen was the fourth of five pre-dreadnought battleships of the Braunschweig class in the Kaiserliche Marine laid down in 1902 and commissioned 1905. Her sister ships were Braunschweig, Elsass, Hessen, and Lothringen. Preussen served in the II Battle Squadron of the German High Seas Fleet for the majority of her career. She participated in a fleet advance in December 1914 in support of the Raid on Scarborough, Hartlepool and Whitby during which the German fleet encountered and briefly clashed with a detachment of the British Grand Fleet. She had been temporarily assigned to guard ship duties in the Baltic in May 1916, and so missed the Battle of Jutland. Due to her age, she did not rejoin the fleet, and instead continued to serve as a guard ship until 1917, when she became a fleet tender.
