Parthian Empire

[Kaiser Kirk]

Ok I tinkered around with the Hapsburg design.  You're right, I can save a great deal if I go with a straight deck, works out to about 3.5m.  However then I not only have to delete the warning, but all the casements drop to only 'limited use in any sea'. If I raise the freeboard to 4m then they are 'Limited use in all but light seas',  but it takes a freeboard of 4.9+m to get them to 'Limited use in heavy seas', which was likely the point in the Austrian design.   
So, I could change the belt warning, and edit the use warning, and then have a disclaimer as to why I made those changes... or I could mimic the freeboard of the original ship.
However, playing with it , I did notice the protective deck was set to single, and yet the notes showed a 25mm capping the casement and a 40mm behind the main belt. So I upped the design 500t and made the 40mm into 55mm - more appropriate for the splinter ranges I expect.

You're right, I can save a great deal if I go with a straight deck, works out to about 3.5m.  However then I not only have to delete the warning, but all the casements drop to only 'limited use in any sea'. If I raise the freeboard to 4m then they are 'Limited use in all but light seas',  but it takes a freeboard of 4.9+m to get them to 'Limited use in heavy seas', which was likely the point in the Austrian design.

Quickly messing around with the Habsburg's linedrawing in paint, the feeboard appears to be a minimum of 5.37 meters. So when applying Springsharp to the actual design, I guess they knew what they were doing. :)

I know from messing around with various sims that if I want to use hull casemates at the below deck position, I need a minimum of ~16 feet for the "Limited use in heavy seas" remark and this is the target I always use for hull casemate guns below deck. This also applies to the part of the hull aft of the midbreak so if the height of the freeboard forward of the break is 18 feet and 10 feet aft of the break, any hull casemate mounted guns aft of the break with the 'evenly spread' option will be "limited use in any sea" even though SS will say "Limited use in heavy seas".

Messing around a bit with SS in imperial, ~12 feet is needed for the "Limited use in all but light seas" remark For the lower deck option, a minimum of ~19 feet is needed for the "Limited use in all but light seas" remark and ~23 feet for the "Limited use in heavy seas" remark.

[Kaiser Kirk]

Figured that instead of doing ships by era, I could present them by role, which might be more coherent. Or not.

So initially, I designed some 1890s scout and protected cruisers to go along with the Armored cruiser, and they were slowish.
Vessels designed to scout for the fleet, to beat smaller things and run from larger... really suffer when engine tech passes them by.
So I'll skip putting out the <1895 one with the simple compounds, but I'm not even sure if the 1900 version will be fielded still. Probably, I need hulls.

So I looked forward and felt that the new cruiser 0.9 comp hull paired with complex compound engines would be a good point
to start a new protected cruiser class, but by then they'd be working on turbines and know things were about to change.
So 1904, with the new turbines, 0.9 hull, new protected cruiser class to build. That way the 1800s PCs could be replaced and scrapped.

However, when I got to working on my 1908 ships it was evident that the old ACs, fast for their time, were now passed up and a new class was needed.

The AC may change, I may downgun to 240mm & 90mm weapons. The main battery depends a bit on the opposition builds by ~1906, while the secondary depends
on the type of destroyers out there, a bunch of 750tonners and 120mm looks more desirable.

The question became - 100% oil fired or not. Parthia has plenty of oil, but buying the 1908 tech costs 6 modification points.  I decided that was not worth it.
So the new ACs and PCs are still 90% oil sprayed coal.

[Kaiser Kirk]

So this is a ship that may or not still be fielded. At 22.5 knots it's getting a little slow,

Compared to it's predecessor, this ship is faster and better armed. While the other could bring 4 x 165mm to bear on the beams, this can bring 7x 165mm.
It also has a minedeck aft, allowing it to be used for offensive mine laying.
Which means I'm posting out of order, the Scout Cruiser-Minelayer should have been prior to this.

This is the aforementioned Scout Cruiser-Minelayer.
With Mines becoming available in 1899, the idea of offensive mine operations would come up.
These vessels are just as fast as the 1900 protected cruisers with half the displacement.
They have a minimal but well sited battery of 120mm, when the opposition is likely to field 75-100mm.
I was figuring only one or two would be built prior to the realization that the new PCs can do this role.

These vessels are supposed to do the roles of both a scout cruiser and an offensive minelayer, and were laid down in 1902, and accepted into the fleet in 1903, and watched turbines turn their high speed into not-so-fast speed.

They can make a 4 day dash at 14knots with 10% reserve, or operate 2 weeks at 10knots.

This is the next generation of armored cruiser, though I may well tinker with the design. I'd like a little smaller, and I'm tempted to aim for better seakeeping. Alternately, I may just put in the notes at what speed she is a Good and at what an Excellent.
For now, it hits the sweetspot I want, it's fast enough to catch the old cruisers, and well enough armed to dispatch them with little risk. 
These will use the new 'Continuous aim & spotting' fire control, and the guns are expected to penetrate over 250mm of armor at the new combat ranges, and over 330mm at the old ranges, allowing it to also be used to finish off crippled battlewagons (as they were expected to in this era).

She does sport the precursor to torpedo bulkheads in the form of shallow bulges. In the meantime, like all my larger vessels, she has torpedo nets as well.  It will fall to the next AC to include torpedo bulkheads.

[Kaiser Kirk]

This is the last cruiser style vessel I'm thinking of, it's mean as a Destroyer Leader.
I don't know about the rest of you, but tonnage is limited on my destroyers and radios are heavy. 25 tons for long range is 5% of displacement on a 500t destroyer.
So this little ship isn't quite as fast as she could be, but offers support to Destroyer flotillas. 
I can somewhat foresee these being ships that get rebuilt later to use for other roles, as destroyers become more robust, that support tonnage could be useful for other roles.

Battleship development.

Trying to decide what to build for battleship pre-builds was/is difficult.  Unlike the European powers, a short range naval war with another major navy is unlikely. Should the Byzantines put a large fleet into the Indian Ocean, the logical base is Aden, there's little in coastal Oman, and it's still 1500nm to the Straits of Hormuz. Control of that chokepoint would be the Coast Defense goal.

With the coast defense + commerce raiding model set in place during the 1870s-1880s, I expect torpedo boats for close defense and long range cruisers for commerce raiding, augmented by a squadron of small slow battleships as blockers would have been in place.

The 7000-8000 ton battleship would an example development of those coast defense vessels.  At 14knts not horribly slow for the period, but short ranged, with a limited secondary battery and compound armor.  The lack of QF guns is not a large problem as there should be no enemy torpedo attack craft in home waters.  The lack of turrets for the main battery would be an issue of increasing concern, as simple gun shields on barbette mounts would not be effective in protecting against batteries of QF with SAP or HE rounds. There should have been a squadron of 4 of these.  With the Suez Canal opening, the strategic situation would change, as the Byzantines could now put larger forces into the Persian Ocean.

There should be a class emulating the US Indiana class, such as USS Oregon, featuring Harvey armor, these would be fairly robust coastal battleships which could serve at sea. I expect at one time there were about 8 of these.  That would give a powerful squadron of 12 CDBBs centered on the straits.

Now, we've dispensed with armor types, which means I can go by history (aka wiki), which has Krupp cemented entering service in 1893. According to Wiki, 10.2" Krupp = 12" Harvey, or roughly 18% better. Other sources indicate that KC requires . Which means the vessels from 1894 on have a substantially better armor type than the preceding vessels.

The 11,500 tons battleship is the next step up, roughly a mix of the Royal Sovereign and Majestic classes in concept. This is the first ocean-going Parthian battleship class,  and would be mainly used to augment the Armored cruisers along the perimeter of the Swahili coast.   Laid down in 1894, they would be completed in 1895, and accepted into the fleet in 1896.

I've got the two Predread classes I keep trying to do , based off Hapsburg and Regina Elena, here as prebuilds they will at least get finished ! Though I won't be pushing the Regina Elena to it's historic speed of 22knots, as they really were more battlecruisers, and I want battleships that look like them. I do however set a fleet speed of 20kt at this point, which gives a premium over foreign navies. allows the Bucephalus ACs to work in tandem with them if needed.


Period wise, one class fits 1895-1900 and the other 1901-1907.

The 1895 gun tech would be finishing in 1896, with new guns being researched 1897-8 and becoming available in 1899 and incorporated in designs/budgets.  So I'll lay down the Hapsburg inspired casement monster ship at the end of the period in 1900, finishing trials in 1903. That would also give 3 years for the fleet to digest the capabilities of the preceding class and decide what it is they want.

Since I get a new gun tech in 1902, which means new guns in 1904, and turbines in 1904 and all-big gun battleships in 1906 (paying 2 for that) and firecontrol in 1907 (paying 4 for that),

This would be followed by a 1904 laydown for the Regina Elena to take advantage of turbines and the new guns, building in 1904-5 and finishing trials in 1906.  1904 would be when research on the 1906 all big-gun would start, and 1905 for fire control, so no additional members of that class as the philosophy changes. At the same time, it is now completely clear that the old coast defense battleships are to slow and weak to be useful anymore, and the improvements in guns, engines and fire control render these now obsolete.

1905 then becomes when design work for the next class starts. At that point, improvements in fire control are known to be coming, but what that means for expected ranges is not yet know. As a result, the armor is scaled for the current point blank ranges.

1906 is when a change really occurs, and concepts regarding all big gun ships with superfiring main batteries leads to the laydown of a new class, the Gilgamesh.

However, at this time, 1906, the Researchers would be half-way through improving fire control- probably having worked out regearing the smaller guns mounts while still working on spotting and plotting protocols.  This means all 12 of the old coast defense battleships are disposable, but even the six newer battleships will be of lesser worth and need to be replaced as well. Designers would go to work modifying the Gilgamesh design, reducing the armor somewhat and improving the lines to produce a slightly more refined and actually smaller vessel, the Enki.

1907 sees the official adoption of the new fire control measures, and a widespread retrofit to the fleet. The laydown of the Enki class would coincide with the widespread scrapping of the old coast defense battleships and old protected cruisers. These older ships would not be suitable for refits as the old style main batteries are slow to reload, they lack quick fire intermediate batteries, the armor is outdated, and they are terribly slow by modern standards.  The previously posted "Tortoise" is sufficiently robust I think those would be kept while the new ships are built, while the Bucephalus class would be the sole cruiser from that time frame to survive, as their very high speed then would make them still useful a decade later. A program of new battleships, armored cruisers and protected cruisers would initiate to take advantage of the technological changes. 

[Kaiser Kirk]

Examples of the earliest, coast defense battleships, would be vessels like Gatekeeper and Keymaster.
To me, these have no fighting value by 1906, and would have been scrapped.

The next series of Coast Defense Battleships would have been more robust.
They aren't *that* expensive, and so I could keep some.
But they are based on the USS Indiana class, including the Oregon....and those ships started getting scrapped in the early 1900s which tells you their perceived fighting value.
So think I will emulate history and strike these from the Naval List of my prebuilds.

I've already posted Tortoise - the first ocean going battleships, and the casement monster. The next battleship is a version of the Regina Elena with significant modifications. Twin 180mm guns in "C" and "W" positions, paired the Regina Elena's trio of amidships turrets, gives the same 10x 180mm firepower as the casement monster. However with 1904 guns available, a reversion to 345mm is done.

Name is but a placeholder until I figure out a better naming scheme.

The question became - 100% oil fired or not. Parthia has plenty of oil, but buying the 1908 tech costs 6 modification points.  I decided that was not worth it.

As far as I can see when looking at the techs, oil-firing is a 1906 tech so would be 2 modification points.

So this is a ship that may or not still be fielded. At 22.5 knots it's getting a little slow

Well, it could be that they are still in use or maybe only a few though more likely used for secondary stuff and not for main battle line stuff like the newer cruisers.

all-big gun battleships in 1906 (paying 2 for that)

All-big gun is 1903 tech and availiabe in 1905 then, not a 1906 tech.

firecontrol in 1907 (paying 4 for that),

There is the 1905 tech which would be a startup tech and available in 1907 and then there is the 1908 tech which would cost you 6 modification points.


... makes me wonder... are you looking at the tech years or that list you made with the years when those techs become available?

[Kaiser Kirk]

Then, in 1906, the All Big Gun tech kicks in.
This is a big ship, a third bigger than the Chariot just above, but with 2.5x the main battery firepower, and still a substantial secondary with the QF 165mm.  I may tinker with this a little, but probably not too much.

The Gilgamesh class was designed to take advantage of the new 1904 guns, 1904 turbines, but more importantly represents a philosophical change from the preceeding battleships. With rapid advances in fire control being evident, and ranges of 6km already being reliably achieved in practice, with promise of greater ranges as techniques improve, the arguments of the "all big gun" club bore more weight. The Gilgamesh was designed in response to that change, but, as the true future ranges is yet unknown, bears armor suited to the old point blank ranges.  Combining the desire to have armor suited for the point blank ranges of her design stages, with the advance in penetration represented by the 345L40, meant a very thick main belt. The Chariot, which had the same design parameters, included her protective deck in the consideration, but with Gilgamesh, the choice was made to go with the belt.

This version has a little extra comp hull, and I'm also torn if I should model AB  Q  XY turrets as 5 twins 'distributed', or as I have here, with Q a separate amidships turret.

The Gilgamesh class was designed to take advantage of the new 1904 guns, 1904 turbines, but more importantly represents a philosophical change from the preceeding battleships. With rapid advances in fire control being evident, and ranges of 6km already being reliably achieved in practice, with promise of greater ranges as techniques improve, the arguments of the "all big gun" club bore more weight. The Gilgamesh was designed in response to that change, but, as the true future ranges is yet unknown, bears armor suited to the old point blank ranges. 

Miscellaneous weight :
162t - Torpedo nets
110t - extra ventilation
25t - long range radio
242t - 1907 Fire Control

... makes me wonder... are you looking at the tech years or that list you made with the years when those techs become available?

I probably am, but I also suspended my prebuild determinations until after we finalize things.
So I may have to shove things around in time a little bit. A year here and there isn't critical.
