The K class light cruisers suffered from many design problems since they were designed and built in the late 1920's and had to adhere to the strict limit's imposed on Germany by the Treaty of Versailles. As the design problems became increasingly apparent, the duties of the ships were limited to compensate and they increasingly failed to serve in the role they were intended to.
The Karlsruhe took part in a few world tours during the 1930's which highlighted some of the design problems inherent in her class. She patrolled the coasts of Spain and Portugal during the Spanish Civil War in 1937 and then spent the remainder of her life in the Baltic before being sunk in the Invasion of Norway. Collected below are photographs of the Karlsruhe in the Baltic from throughout her career.
