The scout cruiser design Ger/CS/1915
I don't believe that I have written about this previously. I have a pencil drawing for a scout cruiser design to be part of the emergency war program for 1915. They were to be called S-8 to S-19, so I would have built 12. The armament was 4-6in QF guns and 4-23.6in TT. The look is very German with two funnels with slanting caps and a raised forecastle that is relatively short. This is the Springsharp report:
