"SMS Berlin 1925" In the "Neverwere" section, the date usually refers to the design study, doesn't it?
In the Never-built-section, yes, but I haven't actually decided what counts for "Berlin" yet. It's still a work in progress after all.
"The turrets are once again based on the Königsberg-class" do you mean the triple turrets of the Köln class laid down in 1926, commissioned 1929-30?
Yes, the Königsberg-III-class/K-class interwar design. The turrets are similar in design, but downsized a bit because they are only twin turrets.
"150mm seemed to be a widely accepted gun size for light cruisers everywhere" Agreed, almost certainly because its shell was the heaviest which could be hand loaded, though the RN had 7.5in on the Hawkins class, and looked at 7.5in on variants of the E class - but hand loading those took two men and a special grab.
I agree the old German 170mm is not ideal, but the 7.5in (190.5mm) on Hawkins was not the same gun as on the earlier armoured cruisers.
Yes, the Germans had the same issues on the pre-dreadnoughts. Originally designed for 150mm secondaries, they were later enlarged to 170mm, but also manually loaded. This put additional strain on the crew and reduced the firing rate.
If Germany is to consider what other nations are doing, they will need to go to a bigger ship with 8in (with Germany an active negotiator at "Washington Mk2" they would probably get the capital ship/cruiser gun size limit set at 210mm instead of 203mm (8in) just as at London 1930 the light cruiser limit was 155mm 6.1in, not 6in, to accommodate the French.
Hm, maybe. Germany did not built any armoured cruisers during the war and at the end, only three (two with 240mm main guns, one with 210mm mains guns) were left. All had been disarmed and removed from active service pretty much since 1916, while the Hawkins-class was brand new. Germany could compromise here, maybe for concessions in other areas.
But what I was really doing was just suggesting you might draw Emden 1921 for the 'Neverwere' section where my interests lie...
I did that a while back. It's not the most up-to-date anymore, but I think it still looks adequate:http://www.shipbucket.com/drawings/4411
