Of the four ships of the ''Mackensen'' class, ''Mackensen'', ''Graf Spee'', and ''Prinz Eitel Friedrich'' were launched, and ''Fürst Bismarck'' was not—but none were completed, after wartime shipbuilding priorities were redirected towards U-boat—and the ships were broken up in the early 1920s. The lead ship of the class was named for August von Mackensen, a prominent military commander during the war. In response to the ''Mackensen''-class ships, the British Royal Navy laid down the s, all but one of which would eventually be cancelled; the sole survivor, , was completed after the end of the war. The design of the ''Mackensen''s was a much improved version of the previous . The most significant improvement was a new, more powerful gun, compared to the gun of the earlier ships. The ''Mackensen''-class ships also featured more powerful engines that gave the ships a higher top speed and a significantly greater cruising range. The ''Mackensen'' design provided the basis for the subsequent ''Ersatz Yorck'' class, armed with main-battery guns, after the Battle of Jutland in 1916 made the need for the larger guns clear. == Design == The fourth and final Naval Law, passed in 1912, governed the building program of the German navy during World War I. The Imperial Naval Office (''Reichsmarineamt'') decided the Navy should construct one battleship and one battlecruiser every year between 1913 and 1917, with an additional unit of both types in 1913 and 1916. Design work on the new class began in 1912, with construction intended to begin in the 1914 budget year. The question about the main battery for the new battlecruisers was the most pressing; the previous was armed with guns, though some consideration had been given to redesigning the last two ships— and —with guns. The 35 cm guns were of course heavier than the 30.5 cm guns, but there were problems with enlarging the new ships to accommodate the heavier armament. The Imperial dry docks were deep enough only for ships with a draft of , and simply accepting an increased displacement on the same hull as the ''Derfflinger'' class would entail a reduction in speed. This meant that an increase in displacement would necessitate a longer and wider hull to keep any increases in draft minimal and avoid reducing the speed. The constraints on enlarging the hull were compounded by restrictions on width imposed by the locks of the canal in Wilhelmshaven. As a result, ''Großadmiral'' (Grand Admiral) Alfred von Tirpitz, the head of the RMA, prohibited a design displacement greater than . The initial design was approved on 30 September 1912, though the heads of the General Navy Department—''Vizeadmiral'' (Vice Admiral) Günther von Krosigk and ''Konteradmiral'' (Rear Admiral) Reinhard Scheer—and the Weapons Department head, ''Vizeadmiral'' Gerhard Gerdes, had to submit any revisions they deemed were necessary. The design staff suggested using triple or even quadruple gun turrets to keep the displacement under the 30,000-ton limit. Another suggested alternative was to use six 38 cm (15 in) guns in twin turrets, one forward and two aft; Wilhelm II accepted that design on 2 May 1913, though ''Admiral'' Friedrich von Ingenohl, the commander in chief of the High Seas Fleet, preferred the 30.5 cm gun of the ''Derfflinger''-class ships. As a compromise, the new battlecruisers were to be armed with eight 35 cm (13.8 inch) guns. The question of whether the new ships should be powered entirely by oil-fired boilers was less controversial. The design staff was generally in agreement with the standard practice of using coal-fired boilers for two-thirds of the power plant, with the remainder being oil-fired boilers. Coal-fired boilers were preferred because the coal, stored in the sides of the ship, provided additional protection, particularly for the battlecruisers, which carried less armor than their battleship counterparts. The finalized design was approved on 23 May 1914. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「}|}The '''''Mackensen'' class''' was the last class of battlecruisers to be built by Germany in World War I.
