Big cruiser (Battle cruiser) SMS Derfflinger

The large cruiser SMS Derfflinger belonged to the same class of ships and was a new development based on the experience of SMS Seydlitz and the ships of the Moltke class. The Derfflinger class was one of the last built in the Empire battlecruisers, but already showed the construction of groundbreaking progress and belonged to the strongest fighting ships of the German Navy.

 

Launching and design:

The design of the Derfflinger class stems from the ships of the Moltke class and the large cruiser SMS Seydlitz, which came out as an evolution from the Moltke class. Completely new was the construction with a smooth deck and the height-adjusted turrets. Of the newer small cruisers, the novel Längsspantsystem was taken over. In addition, the bow was redesigned and was designed completely vertically above the waterline, which increased the speed of the ship.

The combat strength was increased by the use of 30.5-cm fast charge guns in four twin towers, also unlike the predecessor ships. Although British ships had already used the caliber 35.5-cm, but the slightly smaller German caliber were due to the quality and bullet speed equal to those of the British.

The launching of the Derfflinger was planned on June 14, 1913. Due to a breakdown, the ship slipped only a few inches. It was not until July 12, 1913, that the ship could be launched.

Use in the war:

The commissioning took place on 1 September 1914. After some test drives the Derfflinger had its first mission on 16 December 1914, where small German cruisers fired at the British coastal towns of Scarborough and Whitby.

On January 24, 1915, a large push by the German federation on the Dogger Bank in the North Sea to attack the local British outpost boats. The British navy, informed by the interception of radio messages, in turn sent its fleet to meet the Germans. In the following battle on the Dogger Bank Derfflinger received some hits.

The next and last battle for the Derfflinger took place on 31 May 1916 at the Battle of the Skagerrak. There, the ship could sink the British battlecruisers HMS Queen Mary and HMS Invincible, but had to take even heavy hits. Despite the heavy damage, the 157 dead and the invaded 3,000 liters of water, the ship was able to move to Wilhelmshaven on its own. Then it moved to Kiel where the repairs were carried out until November 1916.

After the recovered readiness Derfflinger participated in any further major operation more.

Whereabouts:

According to the terms of surrender of November 1918 Derfflinger was one of the German ships that had to intern in Scapa Flow. When it became known that the German ships lying there are no longer given back to Germany, Rear Admiral Ludwig von Reuter issued the order for self-subversion on June 21, 1919. The Derfflinger sunk around 14:45 clock.

In November 1939 the salvage of the wreck was started. However, as a result of the outbreak of the Second World War, this work was discontinued, as the capacities needed to be used for the war economy. Only in 1948 was the scrapping continued. As a sign for the reconciliation of peoples, the ship's bell and the official seal of the Derfflinger were handed over to the German Marineattaché on August 30, 1965.

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.
