Ships of the Mark: 1907

[Ithekro]

The Kingdom of Rohan, now having several years of experiance as a World Power, has decided to set forth a proposed building plan.  While that plan may take time to fully form there are some basics that need to be addressed.

1.  The Mark needs to build more destroyers or torpedo boats so the older vessels can be retired and because the Mark is short in that area to begin with.

2.  The Mark might see fit to replace the aging protected cruisers with something lighter than belted cruisers as those prove to be expessive.  A return to something of a scouting cruiser or light cruiser may be warrented for the fleet, or perhaps built instead of more destroyers.

3.  Rohan will probably move to building belted cruiser instead of combat cruisers as the combat cruisers are very expensive and it seems there role in the fleet might be taken by the new battlescruisers.

4. In theory Rohan should have one battlecruiser or combat cruiser for every battleship in the fleet.  Presently that is not  the case even with the Snowmane and Valindal under construction.  If one counts the three more powerful belted cruisers and the armored cruisers then the Mark is about at normal levels.  Since the expense to maintian this ideal would be prohibative, it has been suggested that the new fleet ration by 2 battleships to one battlecruiser or combat cruiser/armored cruiser.

5.  Rohan will investigate the idea of fleet matching for both the Pacific and Caribbean Fleets.  While Rohan does not see a clear opponent for the near future, planners have suggested attempting to match the total capital ship production of both the United Norman Kingdoms and the Empire of Nippon.  However, planner have also realized that attempting to match these two powers, while expessive, would also in turn be matching the total prodection of the Russian Empire, which is the number two fleet after France.  Planners have realized that matching France, even with their long stalled naval construction plan, would be next to impossible.  Matching Russia would be nearly impossible, as would matching both of the other two powers as the capital ships of the Mark would have to nearly double to match the currect numbers of ships in the Imperial Japanese Navy and the Royal Navy combined.   Planners will go over the budgets and materials avalible to see if this part of the plan is even possible.

6. Fleet speed standardization.  The Mark does not have a set fleet speed at this time as the technology of the last two decades as jumped the speed of ships from 13 knots to 20 knots for capital ships, and now 24 knots for battlecruisers and combat cruisers.  The Mark is looking to set the battleship speed at 20-21 knots, with maybe having some ships that can make 23-24 knots if needed.  These faster battleships should be able to run down foreign battleships.  This was not standard practise even two years ago as most of out ships were slower than anyone else's.  Now the Mark has finally caught up in speed and maintains somewhat of a hold on the edge of heavy firepower like it has tried to maintain for the last two decades.  Hopefully we can maintian what edges we have.

A new destroyer design, improving on the Shearfoot-class by making the vessel lighter with newer turbines and oil fired boilers.  Everything else is about the same.

Note on Constellation, the turbines are reliable up to 26 1/4 kts (48,000hp, 4 shafts) problems appear over that.

And just to see what people think, the 1909 Battlecruiser of the Mark.

Plan it for this vessel to have an improved turret over the Snowmane and Arcadia, and this have individual sleaves for each gun rather than one sleave for all three guns.  Also the 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.

Hmmm, big and powerful

Scurries off to design 24knot Dreadnought.

[Ithekro]

I found it rather difficult to build a 24 knot battlecruiser using existing turbine technology.  Of course Rohan tends to over guns thing, and is using all centerline/superimposed turret technology, so you might be able to make lighter armed and faster that is armored like a battleship within the 48,000 shp and 4 shaft limit of 1909 engines.

Of course.  ;D

[The Rock Doctor]

Why would Rohan feel compelled to match UNK?  The only coast you share is not especially navigable.  It'd make more sense to me to build a tripwire force for the Caribbean and concentrate on your Pacific forces - which will soon be able to use the New Beleriand Canal to get around, after all.

The Russian Navy is currently impressive, size-wise:  but can that size be sustained as time goes on? 

[Earl822]

I think it is more the other way round, not sure why though

[Ithekro]

Basically I was picking the closest larger powers to balance on (since France is too large to match, and most of the other local powers are rather small in numbers).

As with most plans of this nature, it will likely stay a plan (the United States had a plan around this time to match both Japan and German, plus reserves, so something like 48 battleships...first class battleships I believe).  Rohan will probably at best be able to match Russia's present 22 battleships, but that would be with both first rate and second rate reserve battleships, so more likely 12 battleships and 6 battlecruisers with 5 more older battleships in reserve at best.  The proposed build up to 18 battleships and 6 battlecruiser with 5 reserve battleships is most likely a pipe dream.

[The Rock Doctor]

Fair enough.  I'll be curious to see if you can actually generate those numbers.  Personally, I'm going to be happy if I can sustain eight capital ships.
