Completed in 1901, she was fast for her time.
Now she is slow, underarmed and underarmored.

The notes of the original indicated it was supposed to be a mulit-level protected deck, 20/40, rather than
a single 60mm. The decks should work up to about 10" shells.

The Byzantines have for years fielded a number of 6x 240mm, ~27tkt  heavy fleet scouts, what the Parthians would call 'light armored cruisers'. The Parthians counter these with the Mithradantes and Andar Classes with 10". The Byzantines also have some odd hybrid cruisers with 343m which continue to bother the Parthians.

Under Refurbishment, Waterline can be 'raised or lowered' by 10%.
That is apparently a displacement thing.

I guess it means I can make the draft higher/lower, but I move freeboard
to reflect that. That would actually echo how a lot of interwar ships had additional weight added - they
just sat lower in the water, frequently submerging the top of their belts - or you could blister the hull,
reclaiming freeboard.

To provide floatation, a bulge from the bottom of the belt at -1.65 to the keel at -6.3 is added.
To give that 'weight', 13mm of hull material is added. =93t This is accounted for under HULL & Fittings.

It does mean I could raise the vessel by 0.7m, changing freeboard to average 5.26
and draft to 6.3
That would also change the bottom of the belt from -1.6m to -.9m. Not good.
To compensate for the then-shallow belt, I would have to add a strake of armor below the main belt.
Which is doable.
And it gets the seakeeping to barely doable at 27 knots.

New Engines : 2003
New Bunkers : 1816

The main battery is replaced by the 1913 230L44 178kg
This was developed specifically to replace these ancient 240L40s.

The secondary battery is replaced by 1913 165L43QF 65kg
8x 1911 AA guns are fitted in place of the 12 Anti-boat guns.
Sited in 4 spots - 2 above the main guns, and 2 amid ships,
the new two-gun mount is used.
15mm are fitted for dockside/boarding security and anti-strafing.

New Guns & Mounts : 777t

New Turret Armor :    + 75t on 165mm  = 176

At this point,
a strake of +.75m high x 135mm armor can be added below the main belt.
Belt goes from 667t to 845t = 178t


End belts are removed and replaced with 35mm : 52t

Keeping Byzantine 191mm shells out of the casement area is desirable,
but keeping the Damas class 254mm out of the engines is critical.
So while the superstructure is being remodeled, 10mm of deckarmor plates are laminated on top
of the existing protective deck. Lamination counts as 80%, so boosts to effectively 48mm.
The seperate 20mm deck above the casement would add another 50%, giving 58mm vs plunging fire.

10mm is also added to the forecastel and quarterdeck, to effectively 33mm.  =150t

This is meant to be a modified version of SMS Prinz Aldabert, and a follow on to the Bucephalus class of Armored Cruisers.
Like the Regina Elena class, the forecastle is a tumblehome design to allow the waist turrets to bear forward.
To model this, the forecastle is raised, but a long aft deck is fitted. The secondary and tertiary are assigned the aft deck at the appropriate heights.

Main guns are 240L45, firing a 180kg shell. With a 1895 tech of 1700 ME, adjusted for the bore cross section of a 240 vs. 255mm gun, that is 1503 ME, which yeields a Muzzle Velocity of 839m/s.  That allows penetration of  308mm of armor at 2000m, and 274mm at 3000m, making the vessel a possible threat to period battleships.  By 6000m, penetration falls to 207mm. It is thought that the combo of a 135mm belt and 40mm sloped deck should make the ship resistant to such long range shots.

The intermediate guns are the largest allowed QF weapons, a 165mm L45 firing a 63kg shell at 825m/s. This gun can penetrate 129mm at 3000m, and 87mm at 6000m.  As a result, the main belt is 135mm at it's thickest, but is also backed by the slope of the 40mm protective deck.

The 90mm are anti-torpedo boat weapons.

The protective deck is 40mm over the citadel and 25mm over the ends. An additional 20mm deck is fitted over the casement level.

+6.02 : Forecastle deck
+3.52 : Weather deck, 20mm over casements

Probably more related to the OTL San Giorgio class than the OTL Tennessee class, these feature armor capable of defeating armor cruiser level weapons, and 255mm guns , albeit with dreadnaught style unified main battery. Had I a little more space in my build scheme I might have put forward an 1904 Pisa Class.

1924 refurbishment replaced the main battery with the new 255L47 guns


Range is 28 days with 10% reserve.
A reliance on all oil fuel allows the range to encompass the entire swahili coast and back.

A 25mm upper deck and 60mm protective deck is fitted.
The main belt covers from +0.5m above the crown of the deck to -1.6m below waterline, protecting against diving shells

The extra 500tons 'buys' :
15mm belt & Con armor 165->180
5mm deck armor 60->65
20mm turret face armor 230->250
10mm barbette armor 200->210

That seems worth 500tons.

Weaponry
The 255mm L 47 gun with the heavy shell was developed to take advantage of new artillery research.

While there had been hopes of fielding a 230mm gun, evaluation of it's penetration at
18km was not entirely satisfactory.  Using 18km as a standard by which cruiser sized hulls
are expected to be visible, and so full FC be effective at some point, the desire is
to start to punch holes in cruisers at that range, though decisive battle range is expected
at 14km.

The L47 has slightly less belt armor penetration compared to an L50, but somewhat better
deck penetration. The belt penetration rapidly improves as ranges close.

Secondary
The 120mm guns allow 6 guns forward/aft and 8 guns on either beam.


Armor :
The main battery has heavier armor than the belt,
reflecting that the belt has the protective deck behind it.

The first true foray into "All or Nothing"

The Protective Deck is from 0.65m down to -1.8m

The belt rises 1.25m over the belt and descends
to 2m for 3m total.

The Belt is from 1.9m to -2.0m
A distance of 3.9, but is inclined 10deg so needs 3.96
(3.9 / cos(10) = 3.960 = 3.96.)

Giving an unarmored freeboard of 4.4m.

The 60mm deck will defeat splinters up to 360mm.

TDS
The vessel is designed for Depth of TDS, which drives the Beam.
With 17.4m across the amidships, and 3.5deep on each side, there is a large volume which
should not be flooded, minimizing list from Torpedo strikes

The 3.5m deep side protection has a 19mm STS bulkhead seperating the compartment
in two, and a 38mm (laminated 2x19mm) bulkhead backing the system.

The compartments are an outer 2m wide, and an inner 1.3m (4.3ft) wide.
The outer filled with oil fuel, the inner with air. This is expected to
minimize list if the outer is breached, as fuel and seawater will be exchanged. The
fuel is expected to disperse and broaden the concussion on the 19mm  bulkhead.
That bulkhead is chosen for maximizing deformation ability and toughness.
While also being splinterproof.

The 38mm (2x19mm) provides a backup which will stop any splinters, but is also
able to deform.

The 1.3m (4.3ft) void space between it and the 19mm will allow Damage control
access for leaks, or counterflooding compartment on the far side of the vessel.

Named for the 'White Huns' or Hepthalites that battered the Parthian East, conquering parts and thrusting into the Indus and Ganges valleys.

The Xiyon class is intended to be a "Light Armored Cruiser" to return the vessel to the role of defeating opposing scout cruisers and protected cruisers. Additionally, it is to launch raiding sweeps into enemy rear areas.

The main gun requires turrets, but the shells are far greater than a hand loaded gun can manage,
forming a powerful threat to anything in range...
and the shells are large enough to see splashed out to the limits of visual range.

While 330+mm guns fire slowly and need 8 to alternate 4 gun salvos to maintain spotting,
a 215mm gun fires over twice as fast, allowing just 4 barrels to generate the splashes.
This allows mounting the battery both fore and aft.
 
The 215mm gun fires a heavier shell than the old 230mm, and should have splashes discernable to the Horizon, allowing reliable engagement even when spotter aircraft are not viable.

Secondary on sides has the inner guns raised to fire foreward over the end guns.
Guns are also raised over the main battery fore/aft.

The high cruise speed is to allow it to make high speed cruises through enemy territory, moving 264nm overnight. The expectation also is that when it first encounters a foe it will have a 8-10 knot speed advantage, and while both vessels will increase to maximum revolutions, this vessel will be able to reach maximum speed more rapidly, allowing it to close or depart. 


Main Gun : 215L47 Designed 1932-1933
Fires 20% overweight shells from max 215L60
150.66 * 1.2 = 186.792 = 185


Secondary Gun : 130L47  designed 1930
Using overweight shells, has good punch and range.


Armor 
A debate between extensive light armor to defeat QF weapons of their intended prey, or thicker AON armor to also allow long range engagements with peers led to broad protection with cruiser-grade armor, leaving a single deck level exposed.


Belt : 165mm , +1.9above WL to -1.8 Below WL
Inclined outwards 15 degrees
3.7 / cos(15) = 3.83

TDS rises behind belt to +1.9m
effectively adding 19mm and serving as a splinter barrier for an effective thickness of 184mm

The Belt is capped by Armor deck

End armor is slopes of protective decks,
75mm slopes forward, 105mm slopes aft.
