Vilnius Union Ships, 1930+: The Good, The Bad, and the Unseaworthy

[The Rock Doctor]

Another option for a CLAA.  While I'm not inclined to think the Union would value a CLAA in 1935, the fact of the matter is that it does operate a heap of older cruiser with 130mm main batteries and maybe it could be convinced that the Caribbean is a useful place to have some.  We'll see, or maybe we won't. 

General layout is best pictured as an early Atlanta-type, minus C-turret.  Bear in mind that the mid-break would place B and X at the same level, A and Y at the same level, and Z a level below that.

The two beam guns are just in front of the hull break to allow for decent firing arcs.

Overall I agree that while we're all looking at CLAA, there's really only an iffy need for them yet.  Probably late 30s the need will be more apparent.

If I wanted a 30 knot battleship, it's gonna cost me several thousand more tonnes than the 27 knot ship.

Yes, they balloon quickly. Makes it hard to field the numbers one may want, not to mention a supporting fleet.

[The Rock Doctor]

Indeed. It's something I'm thinking about more in the context of my older battlecruisers being almost twenty years old, rather than a question of wanting fast battleships to hang out with carriers.

The actual Kepler class will probably grow by a few hundred tonnes so I can notch the main battery barbettes from 380 to 400mm.  Sims are still being tinkered with.

[Kaiser Kirk]

I wound up looking at what I wanted my newer battlewagons to do....and while it was tempting to go for the 55 tonners, I just couldn't see it working with my fleet design.  The Arwand class is slightly faster than Iberian ships (Malta signatory), and can face off with Byzantine or Roman at any range. Plus they can mix in with my 'fast wing' 26kt DNs.  Because of Jeftge's BCs, and likely IJN ones, There is still a role for a capital ship that can keep pace with the cruiser screen, so I need a Dahae follow on. But my AC's 255 gun can penetrate most BCs out pretty far.  I've somewhat decided to leave the role of "chase down cruiser" or "solo raider" to the Armored cruiser and Cruiser classes. The Xiyon class has sufficient speed nothing can overtake them, and can beat any cruiser and is even odds vs ACs. 

[The Rock Doctor]

Revised Kepler for heavier barbette armor.  I've also allocated more space for command facilities than I usually do.  This shouldn't change my sketch and doesn't greatly impact my production plans.

Is that a monolithic 17in belt....or a decapping system?

[The Rock Doctor]

90mm decapping plate over a 350mm main belt.

[The Rock Doctor]

Looking at that battleship and wondering how many single 25mm autocannons I can jam into that sucker in 1941.

[The Rock Doctor]

The E-class sloops are an upgrade to the 1931 Bremen class ships and will serve the same basic function - ocean-going trade defence.

The slightly fuller, slightly longer hull allows for greater bunkerage.  Revised weight distribution allows for the installation of a Huelsmeyer device topside.  A few more light AA guns are added.

Consideration was given towards installing minesweeping gear rather than a towing rig, but the latter seems more useful for the ocean-going role.

[Kaiser Kirk]

What do you mean by 'towing rig'?   Sounds like something to assist vessels in distress. Seems an odd addition.

[The Rock Doctor]

An updated flight deck cruiser for scouting and counter-scouting in the North Sea and North Atlantic. 

The airgroup would likely be 8 each of scout-bombers and fighters.

[The Rock Doctor]

Note to self to sim refits for warta, ks-11 and quackenbruck for 234 report...

[The Rock Doctor]

The refit of the two Warta-class light cruisers primarily involves completely replacing the armament.  The old LA 130mm guns are replaced by modern 2-gun DP installations, the lighter batteries are much heavier.

The ship adds new fire control and a Huelsmeyer device.

A sacrifice comes with the removal of the single floatplane once carried between the first and second funnels.  With no space for either a hanger or a catapult, its utility has been somewhat limited and wear and tear has been noticeable.  The space will be used for some of the new AA battery.

Cost:

-New armament:  $0.398/0.199 BP
-New armament armor:  $0.052/0.052 BP
-New FC/Huelsmeyer/NF stuff:  $0.07/0.070 BP
