Big cruiser SMS Roon

The large cruiser SMS Roon belonged to the same ship class, which consisted of only two ships and were built shortly after the turn of the century. These ships provided the transition from the class of armored cruiser to the big cruiser.

 

Launching and design:

At the beginning of the 20th century, a draft was required by the German naval office to replace the two ships of the Kaiser class of 1874. End of 1901, the design was firmly established, which was strongly based on the just recently designed Prinz Adalbert class. The most striking differentiator was instead of 3, now 4 chimneys. Due to the installation of 16 water tube boiler another chimney was needed. The Prinz Adalbert class, on the other hand, was designed with 14 Dürr steam boilers, which required less space in the ship.

The launching of SMS Roon took place on June 27, 1903, the commissioning on April 5, 1906.

History of SMS Roon:

After the commissioning and the subsequent test drives, the Roon was assigned to the reconnaissance forces and participated together with other ships in the annual fleet maneuvers.

In 1907, the ship also served as a troop transport for soldiers who were brought from Germany to the German colony to Tsingtao in Asia. A visit to the US led the ship in the same year as well.

As on March 20, 1908, the British battlecruiser HMS Invincible and on February 19, 1911, the German battlecruiser SMS Von der Tann Indienst was made, these new ship types were superior to the older armored cruisers in speed and in firepower. During the year 1911, SMS Roon was therefore decommissioned and assigned to the reserve fleet.

 

 

 

Use in the war:

With the outbreak of the First World War, the SMS Roon was reactivated and the III. Assigned to reconnaissance group as flagship.

From 30 June to 2 July 1915, the Roon was involved in the German advance near the island of Gotland, where it survived several battles with Russian armored cruisers slightly damaged.

Since the Roon, like other older ships, had no or only an insufficient underwater protection against submarines and mines, the ship was decommissioned in 1916 and initially used as a barge in Kiel.

 

 

 

Whereabouts:

As the war progressed, naval planning began rebuilding the Roon as a naval aircraft carrier. In the middle of 1918, the conversion was started, but this set back a short time later completely, because the Marineamt had opted for a real aircraft carrier.

After the capitulation of the German Empire, the Roon did not have to be interned like most other ships or be delivered to the victorious powers.

During the year 1920, the SMS Roon was finally decommissioned and deleted on November 25, 1920 from the list of warships. From 1921 began in Kiel scrapping.

The Kaiser's Battlefleet: German Capital Ships 1871-1918

The Kaiser's Battlefleet: German Capital Ships 1871-1918 Hardcover – March 15, 2016

The battleships of the Third Reich have been written about exhaustively, but there is little in English devoted to their Second Reich predecessors. This new book fills an important gap in the literature of the period by covering these German capital ships in detail and studying the full span of battleship development during this period. The book is arranged as a chronological narrative, with technical details, construction schedules, and ultimate fates tabulated throughout, thus avoiding the sometimes disjointed structure that can result from a class-by-class approach. Heavily illustrated with line drawings and photographs, many from German sources, the book offers readers a fresh visual look at these ships. A key objective of the book is to make available a full synthesis of the published fruits of archival research by German writers found in the pre-World War II books of Koop & Schmolke, Großmer's on the construction program of the dreadnaught era, Forstmeier & Breyer on World War I projects, and Schenk & Nottelmann's papers in Warship International. As well as providing data not available in English-language books, these sources correct significant errors in standard English sources.
