The Cöln class was a class of two small cruisers of the Imperial Navy , which were used at the end of the First World War .
General
The Cöln class was the last series of small cruisers of the Imperial Navy . Designed in 1914, the original plan was to build ten units. By the end of the war , however, only seven ships were launched. The rest ( replacement Cologne , replacement Emden and replacement Karlsruhe ) was no longer ready.
The seven ships of the Cöln class - like the units of the Königsberg class - were given names of small cruisers that had already been lost in the course of the First World War, but compared to their predecessors they had a bowed stem, were larger, faster and more powerful armed.
Due to a lack of personnel and material, only the Cöln II and Dresden II could ultimately be put into service in 1918. However, both ships were hardly ever used. After the war they were interned in Scapa Flow , where they scuttled themselves on June 21, 1919 .

technology
hull
The hull of a Cöln- class cruiser was 155.5 m long, 14.2 m wide and had a draft of 6.43 m with an operational displacement of 7,486 t .
drive
It was driven by 14 steam generators - eight coal-fired and six oil-fired marine boilers - and two turbine sets with which a total output of 31,000 hp was achieved. These gave their power to two shafts with one screw each . The maximum speed was 27.5 knots and the maximum distance traveled was 5,400 nautical miles at 12 knots.
crew
The 559-strong crew consisted of 17 officers and 542 NCOs or crews .
