Projected German naval construction for 1947 sees few new designs at the moment.

1. The Torgau class Fleet Destroyer - the eventual replacements for the refurbished Z214 class destroyers that will soon pay off to the reserve

2. The Amazone class Corvette - a follow-on to the current Bussard class

Thanks, just curious. Nice design BTW!

Just when I thought the 6in cruiser was dead the Germans bring back to life the General Belgrano design and pump it up some more!
Well armed, very well armoured for a CL, fast and excellent range. This is a tough cruiser to beat, for commerce raiding I'd say very deadly and in terms of fleet escort she has the kind of surface and AA firepower to offer valuable defence.

The Kriegsmarine's "Gun-Club" is happy to have surprised you. :D

I worry whether such a ship is an anachronism at this late date, assuming they complete in 1949, given the inevitable rise of automatic main guns and more sophisticated methods of aerial and underwater attack?
My trend is towards smaller cruisers, another reason my 6in designs were not inspiring me.

I suppose they are somewhat of an anachronism in that they don't have automatic 15cm guns; I'll not go into my reasons for eschewing them - I think I've made that clear before. Germany is building enough air defense ships (between the Asperns and the Wiesbadens) but is very short on gun cruisers. So for once the "Black Shoe Gun Club" triumphed over the "Brown Shoe Aero Club".

Somewhat similar with me. The last ~6" cruiser for Japan was the Naka class from 1934. All light cruiser classes after that one carry the 5" gun as main armament. Looking at the UK, I see the same with the last 6" armed cruiser to be built being the 1935 Colony Class and Scylla Class. All later cruisers laid down are armed with the 4.5" DP or 5.5" automatic.

The Russians may surprise you as well, since I'm still planning more 6" armed cruisers.

I would think that the Russian ones you are planning would be somewhat like the Avrora-class which is armed with automatic ~6" guns.
