Quite a nice design and similar my own above. More speed, less armour. Just depends on what your priorities are.
Korpen, I think the main problems with your design lie in the detail. Need separate boiler/turbine rooms for better torpedo protection > two funnels. Deckspace seems to be a bit of an issue when light guns are added. I went for a similar method in making the Atpbh taller to act as a splinter plate.
Very nice ship, more dangerous to capital ships, less dangerous to a cruisers then mine.
The reason i like ships in this size is just this fact that the different design priorities is so distinct.
I think i am willing to take the penalty of using only one funnel, i prefer the look of single funnelled ships.
But i don't think deckspace is much of a problem of the ship, i felt there are plenty of open spaces on her,
but i have made some modifications on the layout and placement of the 40mm guns (image below).
Also made her 1m thinner, (with the resulting loss of survivability) as that allowed me to increase the deck to 75mm and add 10 shells per gun.
Added platforms on the hangar and funnel as well, mainly for putting 20mm guns on (20mm guns not drawn).
The only dead angle for the AA is from low astern, so maybe i should move a pair of 40mm from the funnel position to the transom to cover it?
