High Quality Content by WIKIPEDIA articles! The Odin class was a pair of coastal defense ships built for the German Kaiserliche Marine in the late 19th century. The class comprised two ships: Odin, named after the Norse god Odin, and Ägir, named after the Norse god of the same name. The ships were very similar to the preceding Siegfried-class coast defense ships, and are sometimes considered to be one class of ships. Like the preceding Siegfried class ships, Odin and Ägir were obsolete by the time World War I had started. Regardless, they were still used in their primary role until 1915, at which point they were withdrawn from active service. The ships performed a variety of secondary duties until the end of the war. On 17 June 1919, both ships were struck from the naval register and sold to the A. Bernstein Company in Hamburg. The shipping company had the ships rebuilt as freighters; Odin served in this capacity until she was scrapped in 1935, however Ägir accidentally grounded near the Karlsö lighthouse on the island of Gotland in 1929 and proved to be a total loss.
