Vilnius Union Ships, 1911 - 1919

[The Rock Doctor]

So we start with a colonial cruiser/gunboat designed for operations in the South Atlantic.  It has reasonably long legs for Union ships, good seakeeping, and uses reciprocating engines for ease of maintenance.  This comes at a cost of mediocre top speed, but is sufficient to deal with non-major power ships likely to be encountered in the area. 

Miscellaneous weight is provided for long-range radio, a platoon of troops and some other goodies.  I'll break that down when my brain isn't dosed with cold medication.

The Patowmeck class cruisers are incremental improvements on the Bug class, and introduce 13cm guns as the main battery for the first time.  A large 10cm secondary is retained for now, though there's a strong push on for the next class to just stick with the 13cm piece.

The gunboat is a decent 3rd class cruiser. For a small vessel, really high freeboard at 6m.  Some of my old ships wound up at 2.0 seakeeping too, as I wrestled with deckspace to do what was needed, a high bow for ocean keeping, and keeping my deck heights consistent.
Anyhow, my 4 gunboats are sloop sized, this is closer to one of my scout cruisers. Which makes me start thinking that if I'm not refitting them (Jefgte's post spurred me to look, and I don't like the cost/benefit) maybe they have a role as colonial gunboat.
When there's assigned misc weight, I'd advocate for some misc weight devoted to a motor launch or something to deliver the troops.

The cruiser oddly has the same bow 6m, but breaks to 3.6 later.
one thing I've been playing with is considering where the main belt sits.  You have 2.44m upper belt, presumably to that rear freeboard.
So that upper belt covers from 3.6m down to 1.16m, and then the main belt covers from 1.16 down to.... -2.44m below waterline?  Seems like you might be able to save a little weight by shaving that belt height.

Otherwise, it falls in the gap between my 3,000 ton scout cruisers and my 6,000 ton protected cruisers (which have much the same role as the French AC Dupuy de Lome).  I don't have a good feel for the 4500 ton class of cruiser and if this one is the killer app of that class or not. Looks like a good vessel.

I am curious why you're sticking with 90% coal. There was a ruling made in set up that each country has at least the minimum strategic resources, so you have an oil supply - probably the marginal German fields are slightly more productive.  Oil is not a concern for Parthia, but we do see value in coal for trade route refueling- but our plans are to have only about 1/3rd of the boilers be oil-sprayed coal to preserve that option.

I would question why 80mm armor, when ~90-100 is the minimum for face hardened armor to work well. For the low low cost of 10mm, you can smash and reject common shells !

I will point out that you've got 1.0 comp hull on both, but per the 1900 cruiser tech, you don't need it : 1900: ammunition hoists, deck torpedo armament, superfiring mounts. Cruisers under 6000 tons may have cross-sectional hull strength > 0.9

Whoa, wait a second, that doesn't say overall it says cross sectional ?  I've definitely been misreading that. Wonder if any designs are out of compliance.
Anyhow, that does mean the the gunboat doesn't fly.

[The Rock Doctor]

With respect to fuel, I'm roleplaying the Union as a bit of a late adaptor to oil-only.  The next generation of capital ships will go that route, but the small fry leading up to that will be mostly coal. Maybe I'll slip something in the news about Big Coal lobbying for this.

The cruiser belts may warrant some tweaking, but that depends on the whole hull strength thing.  I did not realize cross-sectional was the measure.

Third-class cruiser is all I'm looking for out of the gunboats.  I don't think my old protected cruisers would be well suited for the role and am not too keen to dump resources into refitting them unless I need to.

[Kaiser Kirk]

The cross sectional I've posted a query in meeting room.
I think that's a typo, or will get changed.

The goal was overall, and looking at Snips cruisers, that's what he did.

The fuel transition thing makes sense, you came in a little late, so I wasn't sure if you were aware that you have <hand waves> oil in sufficient quantities. 
For Parthia, coal is less available but oil is actually a resource we have in quantity with the Baku fields. As the 1900s develop the gulf oil will be added to that. Also one of my targets in HY1 1911 started producing bunker fuel in 1895, so makes a great base.

As for refitting older ships, Jefgte's post spurred me to try working out springsharps and costs doing refurbishments for all my 1800s vessels -mainly just new guns and new engines, and to my surprise I found the bigger ships seem more "worth it".  The key seems to be engine %.  The smaller ships need the speed improvement more to remain competitive, and the engine sizes on my scout cruisers mean replacing them is a huge cost, but then I get a refurbished old vessel that's barely up to snuff.

After I posted I went and looked at my new Destroyer Leaders, which fit that role and size. I may build more of those in the late 1910s as their tender ability gives some nice flexibility.

[The Rock Doctor]

I was aware of the oil thing, but thanks for the reminder.  I've got that field in Poland and...that's just about it, really.

What if the place that owned all of the Baltic decided it needed fast monitors for the Baltic?

25 and 27 knot variants come at 16.2 and 17.8 thousand tonnes respectively.

Nice  :)

A kind of pocket BC...  ;)

That's no monitor, that's a bloody battlecruiser! If it's for the Baltic do you really need that speed?

[Kaiser Kirk]

Reasonable opponent for the Selkirkshire, but with an 8m freeboard and 8,000nm range....not a monitor.
With the BCs the Norse and Byzantines are working on I'm curious as to the evolution of mid-ranged ships like this.
I've got a wide range of designs I've explored, but Parthia is still buying Jefgte's claim their building an "Armored Cruiser" and figure it's another 8x10" 16,000t style.

That said, while the old Norse ACs have 8.07", which is similar to the German 8.2", the Selkirkshire has 9.84" and both Byzantine and Parthia have 10" guns.
The 150mm armor of the Invincible works ok for 8.2" but falls a bit short for the more recent ACs out there.

6x 300mm vs 8x 255mm when both are vulnerable may not work out to your advantage, as it's more which of the 12 shells/min or 24shells/min make a critical hit first ?

So if this isn't a Baltic Monitor, it may want more belt armor.

[The Rock Doctor]

Thematically, it's a monitor in the sense that Courageous, Glorious, and Furious are - not in the sense of the Lord Clive or such.

Ah. I thought those were 'light battlecruisers' or somesuch.
To me, if they are Baltic ships, the old German concept that normal vision is about 12,000m would factor into armor considerations.
However, you could have a 'Speed is Armor' advocate.

[Desertfox]

Since no one else has a realistic chance of getting into the Baltic, why not drop the speed, reduce draft as much as possible, beef up the TDS (bulges?), and use a more "howitzerish" main and secondary armament (for shore bombardment)?  The armor is probably more than enough to deal with field artillery.

A small segment of the voting electorate was MILDLY PUT OUT by word that the Union Navy had been force to rely - and, indeed, was still forced to rely on chartered civilian ships to re-coal and re-provision the lads out spreading the Loob Doctrine across the Americas, the Pacific, and even Africa.  Why had the Navy not been funded to acquire dedicated vessels of its own for this purpose?  Dozens of lines of text in some of the daily newspapers demanded answers!

The Navy, for its part, had been politely asking for such funds for some time and gotten nowhere.  Fortunately, the time was now ripe.  But what to do?  Considerably capacity was needed, immediately, but one could not have both.

The Navy struck upon a two-pronged approach:  A smaller vessel capable of supporting protected cruisers and such at remote stations, and a large vessel capable of supporting a dreadnought division and its escorts.  But then some within the Navy objected:  Surely the large vessel was a matter of too many eggs in a single basket?  If some dastardly Parthian came along and sank the bloody thing, the whole fleet would have to go back to Amsterdam for coaling!

So the revised plan was instead small, rapidly built ships, plus reasonably sized ships capable of supporting a dreadnought and its charges.

The small one looks like this:
