to that effect I strongly support an uparmoring of the county´s( and the york´s) design to start with, as well as a possible earlier appearance of the Surrey´s.

Awesome, you'll have to avoid stuff like torpedo tubes and probably even turreted secondaries, perhaps just put 4.7 AA guns on the side as an early DP mount? I know that having 3 turrets is heavier, but the RN probably wouldn't want to risk a ship having 50% of its armament knocked out if it looses a turret.

Edit: ninjaed, that was impressively fast.
I am looking forward to it as well. I wonder what would be more important to the RN, having three twin turrets, having 30-31 knots, or having an 8" belt? Looking at the OTL Lions, it looks like what is being asked for is a three turret Lion (or Tiger), with about 3-4 more knots of speed. Given the improvements in machinery, such a ship might be possible. I think it would be easier if it used two triple turrets forward in a Dunkerque layout.
True perhaps the Counties evolve into the Surrey class, OTL the Counties were produced in batches you could do the same kind of thing here. With 12,000 tons you can get a more balanced ship. The RN needs to replace a large majority of its cruisers, and the 8 x 8-inch gunned counties were good long range patrol/raider hunting ships (handsome ships too), give them thicker armour and you'd have an even better ship. Perhaps start off with them being around the 10k ton mark? Not having to worry so much about the 10k limit you could produce them at first with a bit more armour, aircraft facilities already included (perhaps a hangar so the plane's not quite so exposed to Winter North Atlantic?) or go for the full fat 12k ton ship, these would probably be longer, have a true hangar for their scout plane and better protection, but retain the 8 x 8-inch guns but try steer away from any HA ideas for them as it just makes the turrets heavy and more complex, thus expensive.
Other than that, spam the bejasus out of a Leander esque ship and if you need a reduced fat one, you could also have a Penelope type with 6 x 6-inch instead of 8 x 6-inch guns.
In the 30's you could switch it up to a more modern type with 12 or 9 x 6-inch as well as a new heavy cruiser with 9 x 8-inch rifles.
Curiosity, why does it list the guns as 135"?
Also, how much would it save using two triple turrets instead of three twins?

It seems the Dunkirque esque layout is superior in this regard, but it is very radical, its trying to squeeze a fair bit of ship into a rather small amount of tonnage but it could work. Sure with the bigger one you'd have to fudge the numbers a bit to hide that 804 extra ton, or do some more weight saving like taking out the torpedo tubes and reduce the AA guns to 3.7-inchers or drop the speed to 30 knots instead of 31 or other stuff. But still its a fearsome cruiser killer and a light battlecruiser! Damn nice work!
You can fit a lot into 23,000 tons ... particularly with a little wiggle room once they feel confident enough to 'make full use' of the wording.
Interesting, are they keeping the 3x3 16" turrets in the same A-B-Y arrangement, or are they moving them forward? I am trying to figure out a totally different ship that meets the very similar requirements.
