Due to the increasing size and speed of foreign cruisers the Marshals of the Mark have issued for two new vessels to be laid down in 1906 to join the Walda in the slips.

First is the projected 1905 Combat Cruiser Valandil.  With as many 9 inch guns at the previous Narmacil-class cruiser but with more turrets allowing for more guns to be brought to bare  either broadside, and with a speed estimated to be at least 24 knots, this cruiser should be able to keep up and defeat all but the fastest foreign cruisers of the world.  (The hope is that the oil boiler tech will be ready, otherwise she'll be coal only and have reduced range).

The Second vessel laid down is to compliment the Arcadia-class Battleships.  A faster, lighter armored battleship with 12 inch guns in triple turrets like the Arcadia, but with the superimposed design of the Freawines.  The Snowmane-class will be called a Battle Cruiser and will have over 24 knot speeds with turbine powered engines.  Snowmane is not designed for oil boilers but will stay with coal power to be reliable in the years to come.  (If the tech works the next class will have oil fired boilers).  The Snowmane is expected to be able to outfight anything in the sea short of an extremely modern battleship, and be able to outrun any of them.

Boy, I hope none of these ships ever cross my bows in a bad mood... that's some serious firepower and speed. Nothing short of a battleship could stand up to either of these.

Rohan's certainly on the leading edge of naval tech these days.

Ithekro:  why the new triple 12" for Snowmane, as opposed to the twin 14" featured in the most recent battleships?

Ithekro

Well I have these relatively new 12 inch guns and a turret design already.  Also I figure that the rate of fire from nine guns will earn more hits than six 14 inch guns.  At the ranges these things are likely to engage at, the difference in damage and armor penetration isn't going to be all that great, plus the 14 inch guns would probably over penetrate armored cruiser armor.  (This was a problem I found in a close in battle between British battlecruisers and German armored cruisers...it would be worse with larger guns as the ships would have to stay farther away to keep the shells to explode inside the cruiser.)

At least it in not quite bleeding edge...not quite as fast as the Invincibles, slightly better firepower...but at this time...no real fire control...big problem.  Got spotting tops (cage masts), but not quite director control...at least not yet...maybe before she's finished.

Thankfully Rohan and the CSA have a good working relationship (ex. the turbine units in the Floridas).  :)

Well, the Florida's were scrapped on the ways... I lacked superfiring tech, and was given the option to rebuild as a result. I took it. They'll be redone with domestic units.

However, looking at these ships, I would hope that such a relationship is preserved...

These ladies are crazy-scary.

And a plan for a possible H2/1906 design:  It this too much, or should there be another step between the Freawines and this vessel?

Ahoj!
Nice.
Coments - upper belt too thin - 9-10 inches preferrable.
The secondaries are too small.
Main Gun ammunition stocks very small. Although I've seen some ships with such a small allowance, the norm seems to had been around 110-120. It might depend on how big your battleline is.

As to its appropriatness - similar designs had been revealed by the Russian fleet 3 years ago.

I was trying for 7-9 but the balancing act kept getting in my way.  I didn't want to go really huge, but I might have to to make it work.

QuoteThe secondaries are too small.
Well that is the thing.  All I got to work with over 4.5" are old 1880s 6" guns until one gets to the 7.5" and 9" guns.  A new 6" gun is probably needed for the future.  Now if you want the secondaries to drop from the Freawine's 9" to the 7.5", would that be casemate, single or twin turrets?  Or would the 9" go to twin turrets?

The only source of data I have on that at present is the American predreadnough battleships which seemed to carry 60-70 shells per gun on average.

Dreadnought had 3" secondaries, so I dont see a probloem.

Predreadnoughts with a ROF of 0.5 a minute did not need large magazines. Dreadnoughts with higher ROF had at last 75-80 rounds per gun, usually more. Navweaps.com has some relevant data.

Yes, Dreadnaught did have 3' secondaries. And it was the only ship with such armament, secondaries increasing to 4 inch on next class.
And then to 6 inch - 5 years later.

Possible follow on to the Freawine-class.  This time using imported 6" guns from the Confederate State of America.  Also using three sets of turbines (though only the 9,500 shp model) to keep a rough 20 knots force with Freawine and Arcadia classes.  (will be delayed until 1907 due to the needs to get Walda and the two other large projects finished in a timely manner).
