KM Munich (CL-1942+)
Back to Germanic States Navy page:
The German light cruisers suffered from short rangedness, and this couldn't be cured with steam turbine propulsion so the Germans diagnosed that a diesel propulsion system would have to provide the cure. The "M" type cruisers were to be fitted with diesels of 80,000bhp to give them a maximum speed of 32-33 knots while at a cruising speed of 24 knots the ship could travel 15,000 km's. Scharnhorst was 13,000 k's at 24 knots. Otherwise the design was just a basic 8 gun layout equivalent to the 9 gun ships the British were building at the same time with completion dates 1943+.
The name of the class is taken from the letter designating the first projected unit. As long as the ships were not named, they were referred to by letters assigned in the chronological order of their planned construction. The first planned unit would have been the thirteenth German cruiser and was therefore listed as 'Cruiser M' in the navy's documents. Had any of the ships been built, the class would have been named after the first completed unit.
I found this image on an Image Shack link from a Google search on "M class cruisers' - it was uncredited but looks like it is a still shot from one of the Naval Simulation Games. If someone wishes to tell me its lineage I will be happy to credit them. Thanks to Karle94 and Silent Hunter 4 for the pic.
These ships make a stark contrast with the Magdeburg class, where the demands of different roles mean you end up with entirely different ship types. The Magdeburgs were first and foremost escorts to the fleet carriers, for AA and anti-ship duties. The Munichs were built as general light cruisers that could undertake all the roles of the cruiser, escort, raider, scout etc.

The 6.7" guns for my M type come from the demilitarised old pre-dreadnoughts being used as accomodation ships at Kiel harbour.
Or more precisely the guns are off a 1/650 Tirpitz and are too big to be 5.9 - next German size up is 6.7".
