The 1909 Battlecruiser of the Mark.

The plan it for this vessel to have an improved turret over the Snowmane and Arcadia, and thus have individual sleaves for each gun rather than one sleave for all three guns.  Also this one use of the imported Confederate 6 inch guns and full oil fire on a slightly improved turbine (to keep her at 24 knots).  This vessel makes the improvements to several naval yards to Type 3 with Type 3 slips and dock a priority.  Also a fourth turret.

(Felaróf was the horse of Eorl the Young and father to all the mearas.)

These new Battleships of the Mark introduce the triple 14" gun to the Navy.  Not entirely sure if it will be funtional, the vessel is equipt with two triple mounts and two twin mounts.  This vessel also used the imported reverse engineered Confederate 6" gun and has a torpedo bulkhead in response to the effectiveness of Swiss and others torpedo fire during the resent war.  One diffuculty in this design process is that the Helm Hammerhand-class is not even completed before the next class begins to be built.  Only limited operational experiance with the Snowmane, Freawine, and Walda can help designers at this stage.

gah noooooooo its my Italia class >.<... WTB more damn BP.  lol it realy is almost identical to the Italia class i want to lay down

Aragorn or Felaróf?  (I assume Aragorn).  I've actually had this sitting for some time now, and mostly have been debating when to build it.  One version was for 10 guns in all twins (like New York) and then this one (like Nevada) to be the one after than in 1911 or 1912 with the hopefully improved engines.  Then I realized that I didn't need to wait for better engines, I don't want the battleship's fleet speed to be over 21 knots, so it doesn't matter all that much if they are 1909 or 1912 engines for these battleships and with the 14" triples ready, I can build these now rather than later.

The Felaróf-class is a basic improvement on the Snowmane (add a fourth turret and upgrade the secondary guns from 4.5" to 6").  I don't know exactly what the 1912 model Battlecruiser will be yet.  I suspect a nine guns triple 14" gun speed demon version of the Helm Hammerhand followed in 1915 with a 12 gun version of the same thing.  Due to engine restictions they might turn into twin turret versions that are really fast.  Don't know for sure yet (was thinking 16" gun twin versions, but I should wait on those until I'm sure I can have the technology for such a thing).  On the other hand, there may not be a 1912 Battlecruiser and instead the Mark will just build more Battleships and finally fill out the lower end of the fleet again.

Aragorn, lol my hold up is work on the tripple 14" mount >.<, well that and i cant afford to lay one down yet.  I hate being a broke ass lol, but meh nothing i can do about that (should have asked for Maoria its listed as a super power after all) just have to make due building 12" ships for now.

Extremely short ranges for a ship so big and having oil firing. As no strokers would get tired, the ship will travel mostly faster than 10kts. The minimum should be the 8000@10 range of Nevada or the 3000t oil bunkerage of the QE.

Stability for both ships is barely acceptable, I'd say reduce the trim, and forget the "stable platform" rating.
I'd note that SS2 does not like having twin and triple turrets together..
100t misc weight is very little for a 25000t ship.
The 1" torpedo bulkhead will rupture by any explosion, the minimum thickness should be 1.5".
The BC has lower freeboard than the BB.

Modifed, but does not comform to standard specification of being very seaworthy and stable in battle.  Range increased to 6,000 nm at 12 knots.   Armor is probably too heavy as it takes up over 37% of the tonnage.

The Rock Doctor

The Mark's sitting pretty, having little to do but build capital ships...

The designs look good, no obvious criticisms...

Ithekro

Perhaps, but the Mark is also scrapping old destroyers and torpedo boats like crazy (Denethor as well).  With that reclaimed good they should be able to rebuild Goldwine and Theoden as they has planned to do in 1908. 

Current thinking is that Rohan will scrap all the old Torpedo Boats and Destroyers in the Caribbean and Northern Pacific Fleets while the Central Pacific Fleet's Yards are busy building Confederate destroyers for the next year or so.  After that the other old torpedo boats and destroyers can be scrapped (along with the old ex-ACM belted cruisers and probably Boromir) followed by those larger ships that are not sold in 1909 (unless it seems worthwhile to refit and hand on to some of those old ships for coastal/harbor defense).

Aragorn is laid down in early 1909.  Narm and Felaróf will be laid down later in the year.  With the material recession of 1906 - 08, all of Rohan's ships will be late finishing construction for a time.  Constellation and the three belted cruisers will be completed in 1909 however.  (Now who gets to keep Constellation....that is an interesting question.  She won't be delivered until the very end of 1909 so she won't effectively be useful until 1910.  The question is who will own her?  The Swiss?  The Japanese?  Brandenburg?  Rohan?  It will depend on what is happening in New Switzerland I imagine.

The Rock Doctor

You assume New Switzerland won't get into another war before she's completed...a risky proposition, methinks.

What was the rebuilding of Goldwine/Theoden - jacking up B turret to superfiring?

Ithekro

#10
Essentially a raised "B" turret and more modern engines and updating the guns. Light displacement goes up by 200 tons and she trades fuel space for engines (though with added oil fired boilers at 10% to assist with that space problem) She increases her range and cruising speed so she can keep up with the slightly newer Elfwine-class battleships.  This also gets the older model 12" guns out of service at last (when the older battleships are removed from servive in 1910-1912) as this was the last class fitted with them.  This will leave only Elfwine herself that will need a rebuild to raiser her "B" turret as Eomer was rebuilt as the prototype and Brytta was finished with a raised turret.  Ironic since it was the damage to Elfwine's "B" turret that started the process to raise the turrets in the first place.
