keep out the political Offtopic and focus on the ships.
Second advice: please stop the political discussion. This is AU (complete fictional) and this is a shipdrawing forum.
Now for your advices about the Stettin class:
The middle 10,5cm: it is placed good, the firing angle is good, too. It is not placed above the torpedoes but more to the centerline. Might not be clearly visible. The ammo is stored between the aa-directors above the beginning of the funnel.
Change place of the mid 10,5cm with the boats: Just no. The the boats would get out of the range of the main crane. The crane can serve the boats, the aircraft and the loads. I won't install an additional crane.
The recon aircraft: very most of big ships of all navies were fitted with radar and recon aircraft until the end of ww2. Aircraft were for other purposes, too.
The position of the forecastle is good. The Stettin is a cheaper cruiser than the Hippers but with far more range and durance but reduced firepower. The foreship is designed to keep much more dry than all its predecessors.
Additional 10,5cm turret: I would add more 3,7cm aa. There are none by now, what is very unusual.
Thank you for your thoughts, they were very constructive.
