SMS Roon was the lead ship of her class of armored cruisers of the Imperial German Navy. The ship was authorized under the second Naval Law in 1902, and built at the Imperial Dockyard in Kiel at the cost of 15.3 million marks. The ship was named after Albrecht von Roon, a Prussian general and politician. She displaced up to 9,875 metric tons (9,719 long tons; 10,885 short tons) and was armed with a main battery of four 21 cm (8.3 in) guns. Her top speed was 20.4 knots (37.8 km/h; 23.5 mph).

The ship participated in several actions during the First World War, including the raid on Scarborough, Hartlepool and Whitby, where she acted as a scout for the High Seas Fleet. Roon also saw duty in the Baltic Sea, including a battle in July 1915 against Russian cruisers and shore bombardment missions. After 1916, Roon was used as a training and barracks ship in Kiel until the end of the war. It was intended to convert the ship into a seaplane tender, but the plan was eventually abandoned. The ship was struck from the naval register in 1920 and scrapped thereafter.

Roon was ordered under the provisional name Ersatz Kaiser and built at the Imperial Dockyard in Kiel under construction number 28. Her keel was laid in 1902 and she was launched on 27 June 1903. Fitting-out work was lengthy, but was completed by 5 April 1906, being commissioned into the Imperial German Navy the same day. She had cost the Imperial German Government 15,345,000 Goldmarks.
