SMS Mackensen was the lead ship of her class of four battlecruisers built for the German Imperial Navy during World War I. Construction of the ships was stopped towards the end of the war, with the ships in various stages of construction. Mackensen was named for German Field Marshall August von Mackensen.
[edit] Design
The first ship of the class, Mackensen, was ordered in peacetime, with six more ordered during the wartime construction program. Although initially intended to carry 38 cm guns, the ships were built with 35 cm guns so as to keep their weight down. However, when it became known that Britain was building battlecruisers with 38 cm guns (HMS Renown and HMS Repulse), the design of the last three ships in the class was modified to accommodate 38 cm guns, and came to be known as the Ersatz Yorck class because the lead ship was a replacement for the armored cruiser Yorck, which had sunk in 1914.
Mackensen was laid down on 30 January 1915 at the Blohm + Voss yards in Hamburg. She had a length of 223 m (732 ft), a beam of 30.4 m, a draught of 9.3 m, and a designed displacement of 35,300 tons. The armament consisted of eight 35 cm guns, fourteen 15 cm guns and eight 8.8 cm guns as well as five torpedo tubes. Four engines were to give her a maximum speed of 28.8 knots (53.3 km/h) and a range of 8,000 nautical miles (15,000 km) at 14 knots (26 km/h). The crew was to number 1,186 men.
[edit] Fate
The war ended before any of these ships were completed. Work on Mackensen was stopped 14 months before completion and the ship was broken up in 1921. Construction of her sistership Graf Spee was stopped shortly after the end of World War I on 17 November 1918, more than a year before completion, and she was scrapped in Kiel from 1921 to 1923. Prinz Eitel Friedrich was about 21 months from completion when construction was stopped; she was launched after the war and scrapped immediately thereafter. Fürst Bismarck was never launched and scrapped in the shipyard in 1920-1922.
