Springsharp might not handle reinforced bulkhead style TDS properly, as opposed to the 1920s and later style systems with multiple layers.
I redid the two 1914 designs in SS2 adding a superfiring turret. That's doable but adding a TDS isn't going to happen, the designs are just too tight...
Any thoughts on dreadnought heavy cruisers and fast battleships, as posted earlier?
I would suspect that armoured cruisers would make their appearance again once the size of battlecruisers hit high enough. Historically, the large cruisers developed, in the Royal Navy, the US Navy and others, as means to create escort ships that would be able to maintain speed and station with the battlefleet in heavy seas.
There would be a gap in the battlecruisers and the 6in gun armed scout cruisers that could easily be filled by large cruisers mounting 7.5in-12in guns.
One can see the Panzerschiffe as the cruiser killer later with the Alaska class BC as the ultimate ship. But these ships were too big and too costly if one compared it with the battleships but less armed.
When do you think the larger heavy cruiser/armored cruiser type ships would have begun to emerge? It seems the battleship and battlecruiser merge into the fast battleship around 30,000 tons, providing a sizable tonnage gap for cruisers around 10,000 to 20,000 tons.
This means an evolution of these ships as well.
Nature (and navies) abhore a vacuum. Absent the WNT, the size of capital ships (BBs, BCs and the merged "fast battleships") would have increased into the 50,000-60,000 ton range by the late 1920's, with gun calibres up to 18' or even 20' being introduced. These ships would be incredibly expensive so fewer of them would built. Given the fact that existing cruisers were essentially lightly-protected scouts displacing 5-7000 tons, the major naval powers might believe they have need for reasonably powerful intermediate "cruisers" between the size of super-dreadnoughts and scout cruisers for commerce raiding, hunting down commerce raiders, and patrolling colonial seas. Just as with the WNT "treaty cruisers", navies would want these intermediate ships to be sufficiently large and powerful that they could conceivably substitute for battleships or act as part of the fast wing of a battlefleet. In such a world, I could see all major navies (and perhaps especially the smaller ones like France, Italy, and Germany) build intermediate-sized ships equivalent in concept, if not specifics, to the American Alaskas, or a vastly improved German "panzerschiffe" as the new "armored cruiser" or "heavy cruiser" - ships in the 25-35,000 ton range, extremely fast, reasonably well protected, and armed with six to nine 11 to 14 inch guns... with the only other cruiser's being small and essentially unarmored scout cruisers in the 5,000-7,000 range
Very interesting. I think I'll try and work up some SS stats for a few of these...

A version for my Central powers- USA swap TL.
On my version it lists Turret (full) which reads out a Coles/Ericsson Turret when generating a report, and Turret & Barbette as two of several optionsDoes Springtime list 'Coles/Ericsson' turrets as a choice? Since both are obsolete and technological deadends by the 1880s and it would be incorrect to equate modern turrets with those of Coles and of Ericsson.

My guess is that he pressed Turret (full) by accident. Changing it to Turret & Barbette will probably save weight
