 Preussen served with the fleet from her commissioning until 1891 , though she was frequently placed in reserve throughout her career . She cruised the Mediterranean Sea several times during her service , including during a mission in 1877 after unrest in the Ottoman Empire threatened German citizens living there . The ship was withdrawn from service at the end of 1891 and used as a harbor guard ship until 1896 , when she was relegated to being a supply ship in Wilhelmshaven . She ended her career as a coal hulk for torpedo boats . In 1903 , she was renamed Saturn so her name could be reused . The ship was ultimately sold to shipbreakers in 1919 .
