List of Battleships of Germany - Helgoland Class

Helgoland Class

The Helgoland-class was the second type of German dreadnoughts, built during 1908–1912. The class was composed of four ships: Helgoland, Oldenburg, Ostfriesland, and Thüringen. The ships incorporated significant improvements over the previous Nassau type, including more powerful main guns and an improved propulsion system. The Helgolands were easily distinguished from the preceding Nassaus by the three funnels that were closely arranged, compared to the two larger funnels of the previous class. The ships retained the unusual hexagonal main battery layout of the Nassau-class.

The ships served as a unit in the I Division, I Battle Squadron alongside the Nassau-class ships in the II Division of the I Battle Squadron. They saw combat during World War I, including the Battle of Jutland in the North Sea and the Battle of the Gulf of Riga in the Baltic. All four survived the war, but were not taken as part of the German fleet that was interned at Scapa Flow. After the German fleet at Scapa Flow were scuttled, the four Helgolands were ceded as war reparations to the victorious Allied powers in the sunken ships' stead. Ostfriesland was taken by the US Navy and expended as a target during Billy Mitchell's air power demonstration in July 1921. Helgoland and Oldenburg were allotted to Britain and Japan respectively, and broken up in 1921. Thüringen was delivered to France in 1920, and was used as a target ship for the French navy. The ship was eventually broken up between 1923 and 1933.
