SMS Roon was a large cruiser (armored cruiser) of the Imperial Navy . The only sister ship was SMS Yorck . The ship was named after the Prussian Field Marshal Albrecht von Roon (1803–1879).
history
The cruiser was on June 27, 1903 the Imperial Shipyard Kiel from the stack , but was, to put until three years later on April 5, 1906 in service. With a length of 127 m, a width of 20.2 m and a draft of 7.3 m, the ship displaced 9,500 tons. The armament consisted of four 21 cm L / 40 rapid fire cannons in two twin turrets , ten 15 cm L / 40 rapid fire cannons, 14 8.8 cm L / 35 rapid fire cannons and four 45 cm torpedo tubes . Three steam engines gave the ship 19,000 hp and a top speed of 21.4 knots . The range was 5000 nautical miles . The crew numbered 633 men.
The Roon was assigned to the reconnaissance forces and took part in various naval maneuvers and in 1907 in troop transports to Tsingtao and a trip to the USA in the next few years . With the construction of the considerably faster and more heavily armed new battlecruisers , the ship soon became obsolete and was therefore decommissioned in 1911.
When the First World War broke out , the Roon was reactivated to initially serve as the flagship of the III. Reconnaissance group under Rear Admiral von Rebeur-Paschwitz and then to serve as a reconnaissance ship in the Baltic Sea . Because of the poorly developed underwater protection, the cruiser was only of limited use. He took part in the battle near Gotland on July 2, 1915 , during which there was an exchange of fire with the Russian armored cruisers Rurik and Bajan . Two hits were scored; the Roon was damaged by a close hit on the radio antenna. On August 10 of the same year there was a skirmish with Russian destroyers near Zerel. There were also some coastal bombardments on the Courland coast.
In 1916 the ship was decommissioned and moored in Kiel as a residential ship . Considerations to use the large hull of the not overly old and quite fast ship resulted in a conversion plan to the seaplane carrier . Four seaplanes and an armament of 6 × 15-cm-Sk and 6 × 8.8-cm-Flak were planned. Renovation work began in the summer of 1918. However, they were discontinued after a relatively short time, because the design office of the Reichsmarineamt now preferred a real aircraft carrier and wanted to convert the Italian passenger steamer Ausonia, which had been unfinished at Blohm & Voss in Hamburg since 1914, into an aircraft steamer I with the highest priority.
In 1920 the ship was finally decommissioned, removed from the list of warships on November 25, 1920 and scrapped in Kiel in 1921.
