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

[The Rock Doctor]

Glad to see you back. 

I appreciate the insight.

From my perspective, I am not proposing a ship which incorporates non-researched technology.

I will contemplate how to proceed; I was and still am eyeballing a potential 2/1931 laydown but there's just no cash for one in 1/31.

3.Engineers can plan for it- Basically Jefgte's argument
My response is...they apparently couldn't because they did not.
Therefore that is an invalid argument

It is a request from Admiralty to provide a larger air group and a more robust landing deck.
=> The engineers worked in this direction.

[TacCovert4]

Sorry folks, I felt I should step away. My use of the term infuriating was accurate- hence my stepping back for a bit.
I fully acknowledge that this might be incomprehensible to others.

My online debate style can become severely sarcastic, with risk of being insulting, and quite stubborn, turning into that can be perceived as brow beating. While I have never veered into the personal vitriol of online trolls, that does not mean I do not regret some past exchanges. So I felt I should step back and allow the matter to settle.

As for various points

1.Forecastle- on refection, the freeboard setting is the minimum, and so you can exceed it. My comment was in error.

2.Misc Weight Allocation -
Yes, not looking ahead towards techs and the requirements that do not yet exist, nor are you researching was certainly my expectation.

Is anybody not using it to plan ahead?

If you look at my carriers, you'll see I do not have the miscellaneous weight margin for it.
I had not realized others were peering into the future in such a way.
You are carrying biplanes, you are researching more biplanes, you are forecasting monoplane wieghts.
I find this extremely unreasonable.

3.Engineers can plan for it- Basically Jefgte's argument
My response is...they apparently couldn't because they did not.
Therefore that is an invalid argument

So, during the development of the aircraft carrier rules, I looked both at websites and my various books, particular American & British Aircraft Carrier development, but also places like Armoredcarrier.com and even wiki. Wiki is a bit unreliable. There are a number of carriers that had their airgroup size decline, had engineers been able to forecast it , that would not be the case.

For a very simple example of why I find this unreasonable, I will point to the Wikipedia entry for Ark Royal
under design is this passage : https://en.wikipedia.org/wiki/HMS_Ark_Royal_(91)
Along with the inclusion of two hangar decks, this allowed Ark Royal to carry up to 72 aircraft, although the development of larger and heavier aircraft during the carrier's construction meant that the actual number carried was between 50 and 60.[5]

Now, in 1934 the Brits had the most experience in aircraft carriers. While they were a bit behind at by 1941 and are famed for retaining the biplane Swordfish, I suspect that was a matter of wingloading and the low speed needed for torpedo launch, as they introduced the Blackburn Skua monoplane in 1937- the same year the carrier was launched.

They very definitely, despite being a leading aircraft carrier power, and fielding monoplanes ...did not see into the future requirements.

So I was very surprised to find myself in the clear minority on this.
It's not the first time I've had my expectations dashed.
I don't suppose it will be the last.

So that's my piece. Hopefully it illuminates the basis on which I object.


Edit :
One last observation - per the Naval Construction Rules, you can't lay down a ship with technology you have not completed previously.

That may effect my expectations as to "planning ahead" by budgeting weight for a technology that is not even available to research yet.

Don't worry about it. You're not capable of hurting my feelings, I regularly engage in spirited and profanity laced arguments with my best friends. 

Also, as I noted, I was using the heavier weight as a handicap for the RAN rather than future proofing.  But I can reconfigure misc weight on existing designs without problem.  No sweat.

[The Rock Doctor]

So I'm going to build a few of these after all.  They can do some of the things my light cruisers would otherwise be tasked with - close-in naval gunfire support, or gunnery training, or contribute to trade protection in confined areas like the western Caribbean.

An update to the Magdala class light cruisers would basically replace all the old shooty bits with new shooty bits.  I'd also adjust the location of a lot of the otherwise unchanged miscellaneous weight and update the fire control.

I'm assuming it's a refurbishment on account of replacing a mount and hoist main battery.  Cost appears to be...$1.70 and 0.441 BP.

I'd probably do three of the class in 2/31 and the other two in 1/32.  CL Bug II is very similar in design and will probably get a near-identical update in 1/32.

Byzantium plans a large 1931-1932-1933 budget for the replacement of QF guns by DP => slowdown in new constructions.

[The Rock Doctor]

I'm being somewhat selective about what I retro-fit DP to, but these kinds of cruisers seem like reasonable choices. 

[The Rock Doctor]

Refurbishment for the monitor Attakulla, arguably a little earlier than is actually necessary.  Since the only thing that would change in a year or two is the model of fire control, I might hold off until 1932 or 1933 to actually do this, I dunno.

Issue-wise, she has a big secondary battery (12x130) but a light AA battery that might not be adequate at this point.  I noticed I was under-costing the fire control and would need to add 20t out of the limited miscellaneous weight reserve just for that. 

So I'm going to yank out 2x2 130mm and replace them with a bunch of 50mm and 15mm light guns.  The remaining 130mm guns will be replaced with 4x2 130mm DP.  That allows a net weight savings, which I'll put to fixing the FC value, adding nightfighting doodads, and installing a Huelsmeyer device.

I considered replacing 2x2 130mm with 4x2 100mm AA or DP, while leaving the rest of the 130mm as QF guns.  This is actually more weight-intensive and made the NF/Huelsmeyer/weight reserve balancing act very tricky, so I rejected it.

Changing up the 130mm guns should make this a refurbishment.  I haven't costed this out yet, but I'm guessing around $3.50 and 0.5 BP.

[The Rock Doctor]

Barebones refit of the L-class torpedo boats. As previously mentioned, they don't have much weight reserve to work with.

This one basically leaves the main battery in place and adds a bit of light AA and night-fighting stuff.  Torps are updated and I move the enhanced hydrophone package to below-water.  Total cost would be all of $0.06 and 0.053 BP.

I considered yanking out the 100mm in "X" position to replace it with a second twin 50mm and a sonar dome, but it turns out I can do one or the other and not both.

Possible refit of the AM-19 assault minesweepers.

Now, I've bumped main gun shell count from 150 to 250 shells.  The guns are basic QF deck mounts, so maybe that's still possible as part of a basic refit.  If it isn't then I either have to fork over reconstruction costs or stick with 150 shells.  I'd almost certainly do the latter.

Otherwise we're looking at new light AA, new FC, and a bit of night-fighting doodads for a cost of $0.02 and 0.017 BP for each unit.

For discussion:  A light carrier that is under 8,000 t and built to 0.90 HS. 

I understand the last word on this issue was we were going to wait for snip to come back and weigh in but that was quite a while ago.  This provides a sense of what can be done if speed is considered paramount and protection is not.

The airgroup is 20 current planes or 16 post-1933 planes.  Armament is decent for AA, but lame for anti-surface work.  That said, the ship is more of a high-seas patrol/scouting/air defence platform than a North Seas capital ship screener. 

Notionally I'd build one and let the Union evaluate its utility as a small ship, as a training platform, and so forth.

An update to the 500mm monitor, since I've started researching the gun and figure by that logic that I should at least put one on a boat.

The monitor borrows design elements from the preceding Zugspitze class in having cruiser-like protection and a single large-caliber gun in a superfiring mount.  This allows for a fairly shallow draft while retaining six decks under the turret.

Borrowing from the 1929 emergency battleship design is the incorporation of a catapult and floatplane hanger aft, for dedicated spotting.  Placement of the forward AA guns is questionable and it may be that they'll be wrecked by blast effects, we'll see.

The main turret is slightly larger than a conventional triple 350/45 turret, as seen on the Angstrom class battleships.  As the Angstroms will be swapping out their "B" turrets for a new 2-gun turret from 1932 onward, the Union would retain one such turret to retro-fit to this monitor if/when it's decided the 500mm is just too much gun.

Historically, nobody put a gun like this on a ship.  To determine minimum beam, I compared with the aforementioned triple 350mm and gave myself a bit of flex because the hull is full-ish and the turret close to amidships.  Turret dimensions, as shown, are guesstimated from my smaller 450mm/45 sketch, which was grounded on historical designs.

You'd need an enclosed hangar if you're going to fire that turret anywhere but straight forward.  The blast is going to shred anything on deck if you fire it over the beam.  I mean you're lobbing a 2000kg shell, that's heavier than a 21in Torpedo.

[The Rock Doctor]

There's a hanger just ahead of the crane.
