Vilnius Union Ships, 1920+: Electric Drive Boogaloo

[The Rock Doctor]

I'm not 100% certain I can build this until I have the 1918 tech done, which is a couple years off.

But notionally, it's an experimental aircraft landing trials ship.  No launch facilities, though it could probably deal with floatplanes.

But there's a landing deck aft, and a big crash barrier to protect the superstructure.  Below the deck is a hanger for two small and four wheeled aircraft with their wings folder/removed.  A single hydraulic lift services the two.

Notionally, the ship could dispatch and operate floatplanes, and might work as a floatplane tender after the landing trials stuff is finished.  Or I suppose it could be a small aircraft transport, using hanger and deck alike to haul...I dunno...twelve or fifteen planes around.  Or maybe it could serve as a small, mobile aircraft maintenance unit for a forward operating fleet. 

Of note, it uses one half of a recycled turbine set from an old light cruiser, so the cost would be around $2 rather than $2.47ish

An armed tug for salvage, rescue, and other duties like moving floating drydocks around.

Comes equipped with a couple of water cannons ("fire monitor" appears to be the technical term) and towing gear.  The bow is lightly armored for pushing ships around.

I'd build some to commercial standards, notionally.

I'm leaving a little extra so it can handle getting bashed around and so forth.

[Desertfox]

Handy little ship. I should build some myself.

[The Rock Doctor]

A gunship/monitor/coastal defence ship that would recycle both the main battery of the Wspanialy class battleships and the turbine machinery of a Lippe class protected cruiser.  The end result would cost about $7.00 rather than $9.12. 

The main battery is all-forward, allowing for placement of balloon or floatplane facilities aft.

FINALLY

There is a specific refurbishment plan for the Wspanialy class pre-dreadnoughts.

Their anticipated life span is...limited.  They'll likely be replaced in the next 6-7 years.  But a lot can happen in six or seven years, so an effort has to be made to keep them mildly useful.

Re-arming them is not impossible, but studies have shown that the Union would need to down-gun to 25cm for a uniform main battery and that's not considered to be worth the effort on a 15,000 t ship that is twenty years old.  Re-enginging is also possibly, and would provide for a speed of up to around 22 knots but again, is it worth the effort on a ship that is already twenty years old and under-gunned for her size?

So the plan is to keep things on the cheap, more or less.

-A glaring weakness of the class is that their 200mm secondary turrets have a mere 15mm of protection on the sides and tops.  The ship's plans called for 50mm so the discrepancy is a mystery (fraud has been suspected, but never proven).  At any rate, this will be replaced with the actual 50mm thick material it always should have been.

-The tertiary armament of casemate-mounted 130mm guns will be replaced with quick-firing versions.  The quaternary battery of 8x50mm QF guns will be replaced by a quarter of 100mm anti-aircraft guns.

-The bunkerage will be converted to all-oil firing, which ups the range by around 50%.  This'll reduce the number of crew required to operate the ship, make her cleaner, make her more difficult to spot at a distance, and of course let her steam further/faster without people dropping like flies from heat exhaustion. 

-The miscellaneous weight can be increased due to the bunkerage change, so top-of-the-line Model 1918 fire control will be installed.  With the 280mm/45 caliber guns updated just in the last year or so, it'll be a fairly effective main battery by pre-dreadnought standards.  Also additional damage control facilities and much-expanded flag facilities, allowing for command and control of a squadron or amphibious operation.  Torpedo nets have been installed. 

Although miscellaneous weight remains allocated to underwater torpedo facilities, these are considered obsolete and have been sealed off to minimize the risk of internal flooding.

Torpedo bulges were considered but rejected due to cost.

Cost:

-Basic refurb:  $3.033
-New 130mm, 100mm guns and machine guns:  $0.326 and 0.163 BP
-New armor for these guns:  $0.072 and 0.072 BP
-New side/top armor for 200mm guns:  $0.069 and 0.069 BP
-Change to bunkerage:  $0.772
-New miscellaneous weight (all but torpedo rooms):  $0.597 and 0.597 BP

Total Cost:  $4.87 and 0.901 BP

The Schweinfurt class torpedo-boats borrow heavily from other recent Union designs - the Quackenbush class sloops in terms of superstructure layout and the Puck class torpedo-boats for the hull.

The Union wasn't satisfied that it could fit four 130mm guns into this unit, however, so has indeed fitted it with a trio of new 2-gun 100mm/45 QF mountings.  There's some concern that this means the class is under-armed compared to foreign contemporaries, but not  horribly so. 

On the other hand, they have a high top speed, long legs, and are well-suited to anti-submarine operations, so they'll likely be used to screen capital ships.

[The Rock Doctor]

Almost a decade after the Battle of Dakar, there is still intense political debate in the Vilnius Union about whether armored cruisers/battlecruisers/cruisers of the line have supplanted the battleship as the ship of force in the 20th century.

Complicating the discussion is a growing recognition that the Vilnius Union's access to the larger world - including all its external territorial possessions - must flow through one of two choke points created by whatever we're calling the British Isles.  One outlet is around the isles to the north, through the North Sea, between core Northern Kingdom lands.  The other is around the isles to the south, via whatever we're calling the English Channel, tightly constricted by core Roman territories.

If the Union is at war with either of these polities, access to the Atlantic becomes...problematic. 

The perceived wisdom is that a partial solution to this is for Union capital ships to have a sprint capability that minimizes time in these constricted waters and for a hostile neighbour to react to a sortie once initiated.  Bunkerage must also be high to support such a sprint although (SPOILER) the notion of underway oiling is of great interest to Union thinkers right now.  This explains why the Czarownik class cruisers of the line can carry so much more oil than the preceding Szermierz class, and why other, smaller Union combatants have seen their bunkerage increase in recent design work.

All that to say, the next Union capital ship was going to be fast and long-legged regardless of whether it was a cruiser of the line or a battleship.  As it happens, the Johann Encke is considered a battleship, though her armament very closely follows the Czarowniks and her appearance is not that dissimilar.

Encke does carry marginally heavier belts, with greater inclination, and the deck protection is substantially heavier as well.

Of note, the class embarks a single floatplane amidships - unprotected from the elements at this time.

Johann Encke will be laid down in 1/21; a sister is expected in 1922.  It is not yet clear whether the class will extend to four, like the preceding Angstrom class, or if hypothetical battleships G and H will be a later, different class.

On a design note, I'm ret-conning introduction of sloped funnel caps, which I've shown in the Czarowniks and other recent designs.  It just doesn't look right for 1921.  The sketch below illustrates the return to "flat" funnel tops.

Yeah, everything's getting so "Big" so fast now. 

I keep debating what I want to do in 1922 when the Monarchs are complete.  The Implacables are obsolete already, owing to their guns just not having the punch to do anything noteworthy against basically any modern battleship's belt.  The Monarchs are as powerful as you can squeeze out of a BB under 27,000t.  But I'm basically in the same position where my fleet is either fighting in constricted waters like the Gulf, or has to race through Roman-controlled or mayan-controlled waters to get to the Outer Gates. 

I keep seeing these big beautiful fast battleships.....and realizing that I'm going to just have to bite the bullet.

[The Rock Doctor]

They are growing fast, but I don't see incentive to build smaller (in my case).  It's more affordable to build in the speed, armament, and protection I want now than to skimp and do a refurbishment in ten years. 

On the other hand, unless I decide I "need" an Iowa or a Yamato, there's not a lot of reason to escalate beyond where I'm at now.  And they don't make future arms control treaties impossible.  Just maybe difficult.

If the Union is at war with either of these polities, access to the Atlantic becomes...problematic... 

Did you have enough North Sea Destroyers to escort your Battle Line through the 2 Atlantic passages?

I mean its pretty close to an Iowa.

Minimum of four destroyers per capital ship, with the contemporary S class having pretty good legs for the type.

They are growing fast, but I don't see incentive to build smaller (in my case).  It's more affordable to build in the speed, armament, and protection I want now than to skimp and do a refurbishment in ten years. 

On the other hand, unless I decide I "need" an Iowa or a Yamato, there's not a lot of reason to escalate beyond where I'm at now.  And they don't make future arms control treaties impossible.  Just maybe difficult.

I mean its pretty close to an Iowa.

But it is a good ship

I think of it more as a beefier SoDak, but yeah, it's not far off.
