The Magdeburg- class was a series of small cruisers of the German Imperial Navy . Designed in 1908/09, the class got its name from the first ship SMS Magdeburg . It also included SMS Breslau , SMS Strasbourg and SMS Stralsund . The head of the draft department was the real secret naval chief building officer Hans Bürckner , who was responsible for the official draft of 1908/09.
draft
A decisive factor in this new design was the requirement that future cruiser buildings should have side armor in the waterline. The previous version of a curved armored deck with cork dams was no longer able to cope with the increasing caliber strengths of newer foreign constructions. In order not to excessively increase the weight of the ship, the previous construction of the mixed transverse and longitudinal frame system had to be abandoned. The design department of the RMA then developed a new longitudinal frame system, whereby the outer skin itself became the carrier of the ship's strength. The transverse strength was only ensured by the collision bulkheads.
With this cruiser class, the Imperial Navy introduced the bow stern for the first time. This repelled the swell better from the front than the previously classic battering bow. Aft there was no longer a poop - the so-called hut - but this space was used to carry 120 mines on the upper deck. However, this measure reduced the space that could be used to accommodate the crew, so that the crews had to live much more cramped than on the previous cruiser classes. The need for more speed not only led to a higher number of boilers , but also to the installation of a fourth chimney.
The Magdeburg- class ships were the first small cruisers to receive side armor. Until then, one had been content with a pulled down armored deck slope with additional cork dams. However, this posed the risk that the outer skin could tear open even if the armored deck withstood the hit. This side protection extended over 80% of the ship's length and consisted of soft armor material with a thickness of approx. 60 mm. In order to save weight, the armor plates themselves became the outer skin of these ships, whereas in the past these were screwed or riveted onto the outer skin.
In terms of armament, nothing changed at first, except that the diameter of the torpedo tubes increased from 45 cm to 50 cm. Only in the course of the war were the twelve 10.5 cm guns of the last three ships of this class gradually replaced by seven or eight 15 cm cannons. There were also two 8.8 cm guns and two more torpedo tubes on the upper deck.
