High Quality Content by WIKIPEDIA articles! SMS Karlsruhe was a light cruiser of the Karlsruhe class built by the German Kaiserliche Marine (Imperial Navy). She had one sister ship, SMS Rostock; the ships were very similar to the previous Magdeburg-class cruisers. The ship was laid down in 1911, launched in November 1912, and completed by January 1914. Armed with twelve 10.5 cm SK L/45 guns, Karlsruhe had a top speed of 28.5 knots (52.8 km/h; 32.8 mph), which allowed her to escape from British cruisers during her career.
