Dusseldorf, German Training Cruiser laid down 1939

Dedicated training cruisers with secondary minelaying capacity. In wartime, if they were to be primarily tasked with combat service instead of training duties, the training spaces in the aft superstructure would be cleared and the weight saved could be used for additional mine stowage.
