I started to theoritise: IF Dohlar or other major anti-charisian power survive the current war intact, and their industrialisation wouldn't take long enought (let's gave them a credit, shall we?) what type of ships they may be able to create as a counterpart of KH's?
Firstly, let's presume that the main point for the Dohlar navy would be the defense of the Gulf. So, the Dohlaran's ship may not be oceanworthy and have a limited range. They would still be suffucient to defense the area from the Dohlar bank and easter.
We must counclude, that some sort of low-freedoard warship would be sufficient.
Firstly, we need adequate protection from the Charisian 10" long guns. Let's assume that the Charisian guns were at least as good as the USN 10"/40 Mark 3 (from the "Tennessee" armored cruisers) and may be able to penetrate 11" Harvey plate on the distance of 5000m.
If we assume that the Dohlar would be able to produce compound-type iron-steel composite plates, so we need something like 16"-18" compound belt for the citadel. That would protect the magazines and machinery from the charisian guns more or less adequately.
For the ends of the ship, the protection against 8" would be adequate. If we may use sloped deck, we may even go without ends belt at all. But let's assume that the armoured desk is flat. It may be weight-saving to let the ends be without vertical armour... but not with the perspective of Charisian HE shells.
So, our ship must have about 16"-18" in citadel and at least 10" at ends. It would be sufficient to deal woth charisian 10" in realistic conditions (the armour ALWAYS work better in real battle
)
Next: weapons. For my point of view, the optimal configuration would be to bet on the middle-caliber artillery with a few heavy pieces. Let's remember, that a large part of KH's freeboard is unarmoured at all. So, the middle-sized shells would be a perfectly good weapon to pound the KH, so she would be unable to retreat in open sea. For my opinion, the 6" would do the job. Of course, Dohlar probably wouldn't be ablt to build the really quick-firing 6", so we just put a lot of them to do the job.
And we definitely need a few heavy guns, that would be able to penetrate the armour. Of course, they wouldn't be too effective against KH's in sea battle (they would be inferior in therms of range, and reload time, and probably the penetration power), but they should be: our light 6" wouldn't be able to penetrate armour at all, so they wouldn't be able to reach the vital parts of KH's. And besides KH's, there are plenty of Charisian river, and coastal ironclads and other ships with armour to deal with.
It looks like that for the Dolhar would be possible to build something like large Canet guns of 1880th. Let's not forget, that this guns were build (under license) by Spain in the middle 1880th, and the Spain in XIX was totally not a industrial giant.
So, let's stuck with two 280-330 mm Canet-type guns in bow and rear mounts. They would be mighty enough, to penetrate KH's armour on rational distances, and discourage the Charisian about the idea of long-range battle. We may probably go with only one gun at all, but two would work better.
How du we arrange our artillery? Whell, the big guns (let them be 300 mm) should be placed in barbette mounts on centerline. The barbettes MUST have a heavy armoured cylindrical turret-like tops, that would be able to protect them against Charisian 8". I think that the 400mm armour on barbettes and 250mm armour on shields would be sufficient.
The secondary - or in our case primary - 6" armament i would like to place in diffetent levels. I'm thinking about six 6" guns on the gun deck (three per broadside) in casemate mounts, four in the superstructure corners (two per boardside, two as chase. two as retreat) and another four 6" on the superstructure, in offset-diamond pattern (the bow 6" shifted to the port, the rear shifted to the starboard, to avoid problems with a superfiring guns over the main battery). So, we would be able to have eight 6" per broadside, five as chaser and five as retreat, and all six-inch are distributed well enought.
What about speed? Well, it depends of what possible engines would be avaliable fo Dohlar. If we would have triple-expansions, i presume we would be able to have about 18 knots on three to four screws. That would not only lessened the intension per shaft and machine, but also make our ships more maneuvrable.
So... low freeboard, moderate speed, two heavy guns for armour penetration and fourteen 6" for the main work. With 18" compound belt in citadel and 10" in the ends, i think, we could place it in 8000 tonnes, sacrificing the range. Look like some handy, this... "Malikai"-class coastal ships?
