Very interesting.
I think as a practical matter, it takes the 'Riskable Battleship' a bit further than I myself would go: I'd probably cut the speed down to 29 knots and beef up the armour, including a TDS. One of my concerns in this case is putting a quad 34cm turret on this relatively narrow beam.
I'd be interested to see the rest.

Usually the result is: Not worth it. They get the worst of two worlds, not enough planes and handling space, not enough guns and armor. Why would it be different with your design?

Now the airwing is much reduced compared to that of a 17,000t pure carrier (15 vs 40-50). But it is not an insignificant number.

What is such a short flight deck good for? Helicopters?
Well by my sketches, the flight deck is angled 12°. Given a length of 90m, that means the flight deck itself is 92m.

It is not long enough to land a jet on, but a propeller plane took 60-75m to land unassisted on a jeep carrier, so it's quite enough for those.

Given the much higher speed of the ship, I would suppose required runway length would be much reduced.

But a deck for helicopters is always useful.

I did not examine closely the length of catapults and arrested landings for modern jet planes but they seem to be 50-60m and 100m long respectively.

I had originally set for a 100-120m flight deck, but it was lost during the designing. I can always increase the length of the ship to compensate, it would be a 500t-1000t modification (which I will do).

Have you considered turbulences caused by the superstructure?
Well of course I have, but I see no reason that it should be an issue. The superstructure is not located aft, it is located midship. The difference between the normal location is that it's put off on the side a little. But why should this be a more significant problem than that faced by carriers and their arrangement to begin with?

Usually the result is: Not worth it. They get the worst of two worlds, not enough planes and handling space, not enough guns and armor. Why would it be different with your design?
Given that ships of Wesworld in the 17,000t-23,000t are all heavy cruisers with armaments of 200m-230m guns. Would you characterize a 17,000t ship with 8x280mm guns as inadequate in firepower? I wouldn't.

Now the airwing is much reduced compared to that of a 17,000t pure carrier (15 vs 40-50). But it is not an insignificant number.
Quoted
Originally posted by Logi
The difference with the design offers utility through it's small displacement and heavy firepower. It's armor is not inferior to that of the heavy cruisers and it's firepower far superior. Then the air wing is an added bonus. It pays the price of light cruiser fuel range in exchange.

Why is this a better idea than a pure pocket battleship?
The recoil of 8x280mm is very high, so high that you are forced into a hull of 16,000t and above if you attempt to keep the fleet speed of 32 kn.

In other words, the hull cannot go smaller, but it also has a large amount of deck space unused.

Taking this deck space and using it for flight operations is a minimal additional cost to the ship. Also, as you know, the cost of aircraft in weight is exponential so a small airwing complement has a virtue on all it's own.
Since the ship was already intended to be a fleet attachment that bolsters a task force's firepower, the added ability to conduct Recon/ASW/CAP for minimal cost is a good thing IMO.
