...only... :D The 1582 tons don't include the enlarged barbettes, heavier ammunition and the stronger structure around all around the turrets.
Where are those 500 tons of more weight per turret hidden? The H39s turret isn't so much bigger than Bismarcks. It's the armor plating. So I decided to simply lenghten Bismarcks turret and keep the old armor strenght. A 16" gun isn't that much bigger than a 15". But it's power when fired is impressingly higher. And so is the stress that it causes to the ships structure. So the Waldersee wears a Bismarck-turret but a H39s barbette.

The 16'' barrels are more thicker then the 14.96'' so it can fire off those way bigger shells (Those shells are very very very much larger and heavier. And more explosive).
They are also bigger so it can still fire a certain amount of shells per hour, instead of becoming glowing hot and have to cool down for a long time.

The turrets itself has a new reload system wich is also heavier, and the armor is thicker.
The turret is also way larger:

The big new destroyerclass of 1946 shows a significantly larger ship than any german destroyer before. 4000 tons and an impressive armament make the ship the ideal escort for the large vessels in overseas missions.

The hull shape is mostly from the 60s 101 class, recut to the scout-cruiser-design. I like this ship!

But, like the real life 101s, will have poor seakeeping qualities due to low freeboard (in fact it will be worse here since it's significantly more top-heavy). This doesn't mean that you need to go back and change this, but it does mean that every subsequent design will at least make incremental improvements, just as what occurred in the real-life large frigates that replaced these ships.

I have always been suprised that seakeeping is such an issue with German WW-2 era designs.
Given the enviroment in which they would operate, it would seem the seakeeping would be high on the design priorities.

Nice desing, As ridicilously topweigth-lookish as the Type101's in real life, and thus quite awsome.

The finishing is bit sloppy thougth, here is what happens when you paste the drawing in yellow sheet:

You really think, a ship like the destroyer Hamburg with nearly 200 missions overseas had poor seakeeping qualities? What do you think about those engineers who designed the ship, they took their plans from our beginners forum or what? I'm very sure the ships only looks that unstable.
Btw, my 1946 destroyer is reduced by one deck...
@Gollevainen: thanks for advice, I'll make it correct.

Just because a ship has done several missions in foreign waters doesn't mean that getting there was comfortable or that the ship would have been able to fight in transit. The SF300 is a good example. Despite their modest range and murderous whipping in heavy seas*, they've been successfully deployed all over the North Sea and the Med.

*That's what you get when your center of gravity is less than half a meter above the waterline.
