SMS Hagen was the final vessel of the six-member Siegfried class of coastal defense ships built for the German Imperial Navy. She was laid down in September 1891 and launched 2 years later in October 93, and then a year later entered service into the Imperial German navy. Her career was fairly quiet, spending most of her life as her designed role by the German coasttline before being withdrawn in 1915 and sold for scrap in 1918.
