List of battlecruisers of Germany

Seydlitz leads Moltke, Hindenburg, Derfflinger and Von der Tann into internment in Scapa Flow

The Kaiserliche Marine, the navy of the German Empire, built a series of battlecruisers in the first half of the 20th century. The battlecruiser type was an outgrowth of older armored cruiser designs;^{[lower-alpha 1]} they were intended to scout for the main battle fleet and attack the reconnaissance forces of opposing fleets. Kaiser Wilhelm II insisted that the new battlecruisers be able to fight in the line of battle with battleships to counter Germany's numerical inferiority.^[1]

SMS Von der Tann was the first German battlecruiser, built in 1908–1910.^[2] The Kaiserliche Marine eventually built four more battlecruisers before the start of the First World War to serve with the High Seas Fleet, and another two were completed during the conflict.^[3] A further seven were planned, including four of the Mackensen and three of the Ersatz Yorck-class ships.^[4] Two of the Mackensens—the name ship and Graf Spee—were launched but never completed, and the other two were in earlier stages of work when they were canceled towards the end of the war. Serious work never began on the three Ersatz Yorck-class ships.^[5]

Six of the seven battlecruisers completed before or during World War I saw relatively heavy combat, primarily in the North Sea. All of the ships, with the exception of Goeben, which had been assigned to the German Mediterranean Division, were assigned to the I Scouting Group under the command of Admiral Franz von Hipper. The unit conducted several raids of the English coast between 1914 and 1916, which culminated in the Battle of Jutland during 31 May – 1 June 1916, in which they were expected to draw parts of the British fleet onto the German battleship line. The German flagship Lützow was sunk at the battle, and the other ships were heavily damaged. For their own part, during the battle Von der Tann sank her counterpart HMS Indefatigable,^[6] Seydlitz sank Queen Mary,^[7] and Derfflinger and Lützow together destroyed Invincible.^[8] The five remaining battlecruisers—Von der Tann, Moltke, Seydlitz, Derfflinger, and Hindenburg—were interned with the bulk of the German fleet at the British naval base at Scapa Flow following the end of the war. The ships were subsequently scuttled by their crews in 1919 to prevent them from falling into the hands of the Allied Powers.^[9] Goeben was transferred to the Ottoman Navy at the outbreak of hostilities, and operated against the Russian Black Sea Fleet for the majority of the war. She was heavily damaged by British naval mines near the end of the war, but was repaired and went on to serve the Turkish Navy until the 1950s; she was eventually broken up for scrap in the 1970s.^[10]

The eventual successor to the Kaiserliche Marine, the Kriegsmarine, considered building three O-class battlecruisers before the Second World War as part of the Plan Z buildup of the Navy. However, the outbreak of war in 1939 caused the plans to be shelved, and none of these ships were built.^{[11][lower-alpha 2]}

SMS Von der Tann

Von der Tann

SMS Von der Tann was the first German battlecruiser, ordered in 1907. She was designed in response to the British Invincible-class battlecruisers, construction on which had begun the previous year. As the first of a new type, the design process for Von der Tann was highly controversial. Großadmiral Alfred von Tirpitz, the State Secretary for the Imperial German Navy, wanted the ship to follow the British pattern of large guns, relatively light armor, and high speed. Kaiser Wilhelm II, along with other senior navy officers instead argued that, owing to Germany's numerical inferiority, the new ships should have armor strong enough to permit their use in the battle line.^[12]

Von der Tann was present for most of the German fleet operations during World War I, including several raids of the English coast. At the Battle of Jutland, Von der Tann was the last ship in the German battlecruiser squadron. She engaged HMS Indefatigable and, after 15 minutes of firing, Von der Tann's 28 cm (11 in) shells caused a magazine explosion, destroying Indefatigable. At the end of the war, Von der Tann was interned in Scapa Flow and eventually scuttled. She was raised in 1930 and broken up for scrap between 1931–34.^[6]

Moltke class

Goeben in port

Moltke and Goeben, improvements over the preceding Von der Tann, were ordered in 1908 and 1909, respectively. While their design was not as contentious as with the Von der Tann, there were still disagreements between Tirpitz and the General Navy Department over whether the main battery guns should be increased in number or caliber. Tirpitz favored the increase to ten guns, while the Navy Department preferred eight 30.5 cm (12 in) guns. It was eventually decided that ten 28 cm guns would be mounted. In addition to the increased main battery, the two Moltke-class ships were slightly larger and better armored than Von der Tann.^[16]

Moltke joined Von der Tann in the battlecruiser squadron upon her commissioning, and saw action against the British in the North Sea. The ship also saw significant duty in the Baltic Sea against the Russian navy; in 1915 she was torpedoed during the Battle of the Gulf of Riga,^[10] and in 1917, she returned to the Baltic as the flagship of the invasion force that conducted Operation Albion.^[17] Moltke was also interned in Scapa Flow at the end of the war and scuttled in 1919.^[18] Goeben, on the other hand, was assigned to the Mediterranean, as the flagship of the Mediterranean Division. At the outbreak of war in 1914, Goeben and the light cruiser Breslau evaded the British fleet and escaped to Istanbul, where they were transferred to the Ottoman Navy. The ship primarily operated in the Black Sea against the Russians. She attacked British forces outside the Dardanelles in 1918 and struck three mines.^[10] The ship continued in Turkish service until 1973 when she was sold for scrapping.^[19]

SMS Seydlitz

Seydlitz steaming to Scapa Flow

Seydlitz was an incremental improvement over the Moltke class. The ship was slightly larger than the two previous ships, and had a taller forecastle. Seydlitz mounted the same ten 28 cm guns as in the Moltke class in the same arrangement.^[22] Upon commissioning into the fleet, Seydlitz became the flagship of Rear Admiral Franz von Hipper.^[23] The ship took part in most of the major fleet operations during the war. At the Battle of Dogger Bank, Seydlitz was hit in her after turrets by two or three 34.4 cm (13.5 in) shells from HMS Lion; the shells burnt out the turrets and nearly destroyed the ship. At Jutland, Seydlitz inflicted fatal damage on the British battlecruiser HMS Queen Mary. The ship was heavily damaged through the remainder of the battle, and took in over 5,300 metric tons (5,200 long tons) of water. Despite the immense damage, Seydlitz was able to make the trip back to Wilhelmshaven, where she was repaired. As with Von der Tann and Moltke, Seydlitz was interned and eventually scuttled in Scapa Flow.^[22]

Derfflinger class

The three Derfflinger-class ships were the last battlecruisers completed for the German navy. The ships' primary armament was radically modified, compared to the older ships. The number of guns was reduced to eight, but their diameter was increased to 30.5 cm (12 in). They were also placed in two superfiring pairs, fore and aft of the main superstructure.^[26] The first unit, the name ship, was completed shortly after the outbreak of World War I. Lützow followed in August 1915, and Hindenburg joined the fleet in May 1917.^[27] Derfflinger was involved in most of the fleet actions during the war. At Jutland she fired on Queen Mary and contributed to her destruction, along with Seydlitz. Derfflinger and Lützow later concentrated their fire on Invincible and destroyed her. However, during the battle, Lützow was severely damaged by at least 24 heavy-caliber shells and was unable to make it back to Germany. She was scuttled early the following morning. Hindenburg's career was much less eventful; she was completed so late in the war that she saw no significant action against the British fleet. She and Derfflinger were interned and scuttled in Scapa Flow with the rest of the fleet.^[22]

Mackensen class

Following the realization in February 1915 that the war would not be won quickly, the Navy department decided to replace the six armored cruisers that had been lost thus far.^[30] The ships were improved versions of the Derfflinger class; the primary alterations being the adoption of the 35 cm (13.8 in) gun for the main battery, along with a full-length forecastle deck. Four ships were ordered and laid down, but only two of them, Mackensen and Graf Spee, were launched.^[31] None of the ships were completed, as work had been diverted to U-boat construction.^[32] All four ships were broken up in Germany between 1921 and 1924.^[31]

Ersatz Yorck class

The three ships of the Ersatz Yorck class were originally ordered as Mackensen-class ships, but the design was modified in January 1917 to increase the armament to eight 38 cm (15 in) guns. The Ersatz Yorcks were otherwise similar to the Mackensens, with the exception of the funnels. The Ersatz Yorck-class ships were modified to trunk the two smoke uptakes of the previous design into one large funnel. Only the lead ship was laid down, and work did not proceed far; only about 1,000 metric tons of steel had been assembled by the time work ceased. The other two ships were assigned to shipyards, but work never began.^[34]

O class

The O-class battlecruisers were designed in 1937 to supplement the P-class cruisers then planned for the new German fleet. The three ships were armed with six 38 cm guns in three twin turrets, similar to the arrangement of the main battery of the Scharnhorst-class battleships. They were intended for use as long-range commerce raiders, with the goal of forcing Great Britain to disperse its battleships as convoy escorts. The ships were never laid down due to the outbreak of World War II in September 1939.^[11]
