Happened to hit the "show new posts" and what popped before my eyes was your AC5.
The AC 5 is rather impressive, in no small part because it is very similar- better in some ways- to a ship I was planning for slightly later when my build schedule clears.
I do note that she doesn't seem to have any raised turrets, rather they are all flush, which given you're planning to shoot on the beam and she has the length for it, works.
Also:
"Beam between torpedo bulkheads 90,00 ft / 27,43 m"
This means the TDS system is a total of 4m deep, or 2m each side.
The SS doesn't change the estimated number of torpedoes, but it should matter considering warhead sizes later. You have more than enough beam for a 3 or maybe 4m system each side.
You also may want to add 0.1 to the bow, to get rid of the 'wet forward' note.
Also, Fire Control is 1/10th of the weight of Armament: 2 032 tons, 6,5 %
so 203 tons, not the 140t
Overall very nice :)
I need to find time to look at peoples designs on a regular basis, but I can't seem to catch up to stuff before more things get added to my 'to do' list !
I have noted in my 1910 report 28500t (+90t) for AC5.
So fine adjustments ll'be possible without battle performances reduction.
- Turrets are flush deck, similar disposition than Kostenko BC project :D
- I increase TDS by 1'' each side...early 122000SHP take much space :(
- FC is now 203t (125t was an old rule) :(
- 3" guns take the place of the 0.7'' MG

SC1911, Byzantine Empire SC5-152 laid down 1911
Ack you posted another couple ship.
Oh well, this reply goes to this ship, I haven't looked at the the next couple. I see they mimic the Parthian Protected Cruisers in size and weaponry.
On this one :
BC : I don't know what's "right" for ships of this size. To me it seems like the BC is too low.
Worse, the greater the beam exceeds the minimum, the lower the BC can be.
In this case, your beam is about 1.5m greater than comparable 6" gunned sloops.
The beam is only slightly larger than it has to be, so I would want to see the BC 0.5 < .
Admittedly that isn't based on hard data, but
But the block coefficient, at 0.45 , seems in the destroyer range. After all, our minimum is 0.38, you're 0.07 larger – very little.
2 ) I was concerned about length and the amidships 6" , but after looking at USS Erie, which you are longer than. I think that's ok. Your midships guns can go where the seaplane is.
3 ) One thing that is a problem is that you didn't adjust your forecastle/stern lengths when you extended your belt.
The overall length is 124.66m The belt is 110.0m, or 88%
Your forecastle and stern are 25% & 18% for 43% of the length.
Why this matters is that area is what the armor deck is factored from
So currently only 57% of your ship has a 30mm armor deck, instead of 88%.
It's not going to be a great deal of weight, I estimate 30tons, but should be fixed.
SC5-152 is not choose for 1911
Admiralty prefer SC5-191 with
3x191 fore & 3x191 aft vs Cruiser
2x120 fore & 2x120 aft vs TB

At first I found it intriguing combination in a small package.
Then I thought about it and realized it has 1 fewer barrel than a
Enki, less armor, and newer engine, so it should be lighter.... but it's a nifty compact BB.
Unfortunately, part of that is the beam is too narrow; saving deck armor, engine and fuel weight.

(174,96 m / 174,96 m) x 25,60 m x (7,40 / 7,66 m)
I really don't like that beam.
Too lazy to go down the hall to get a book, so I'll use Wikipedia :)
HMS Lion - 27m
HMS Iron Duke - 27.4m
HMS Tiger - 27.6m
HMS Erin - 27.9m
What do they have in common ?
13.5" / 45 caliber guns
...in Twin, not triples.
... discontinuous TDS only over magazines & machinery, not at barbettes, which allows a narrower beam.
What were the beams of contemporary 13.5" triples ....oh weren't any.
But there are some 14"
here's a couple from 2 nations
Pennsylvania : 29.72m
Erzatz Monarch : 28.5m
So I'd really like to see +2.5 - 3m on that beam.
You are right beam is too short with T3x13"5
26000t Ramses II is 30,5m

That's a lot of firepower in a small package. I'm wondering if perhaps a pair of smaller 100-105 mm howitzers might not be better? Since you might not have clear lines of sight in a river.

The Parthian gunboats are even larger, but if you compare them to the Austrian-Hungarian Kormarom class, they are only 3m longer, the difference being in beam. If you start looking at things like the USS City-class ironclads, they are over 500 tons...not much longer but far beamier. Likewise the Austrian river monitor Inn was 536t normal, with a twin 120mm, 3 x 120mm HOW and she was 57.9m x 10.3m x 1.3m
Tonnage isn't as much a restriction as length and draft. A 0.7BC 4:1 L:B vessel is far greater in displacement than a .5 7:1,
As for armament, the only concern would be beam. This is getting into the field of "I know they didn't do these things, but I don't know why".
The Parthians mount a 120mm forward, and an 118mm HOW amidships. So similar variety.
But...
I doubt that searching will find historical examples of vessels- regardless of displacement - with a 6m beam and 120m guns. I think you'll find 75mm is about the largest you find for that beam. The question is if that was because of a physical restriction- like the ability of the hull girder to take firing shock without undue stress, or was it because they did not see a need for a larger gun?

Physical restrictions are the size of the river,
height of water during the dry season and the tight turns.
;D ;D ;D no problemo for the Nil ;D ;D ;D
you are certainly correct that the size of the river matters. The Austrian Hungarian boats were on the Danube, the US on the Mississippi. The Parthian on the lower reaches of the Tigris/Euphrates :)

Like I wrote at the beginning, Byzantine Empire use United kingdom artillery.
So, for the fun, I test BB with HMS Glorious guns => T1 x 457.
Certainly interesting.
While the T1x457 are too slow to do fire control from shell splashes,
I do not see why you could not use the 343mm to create the splash ladders.
However, single-sleeve barrels would be needed to allow each barrel to shoot a slightly different range.
For shorter ranges, you could use the 191mm.
As the "opponent" I would be forced into deciding to armor vs. the more likely 343mm, or increasing all my armor to address the few 457 that may hit.
Though with a low MV /40 cal, the difference may not be huge.
Not going to worry about construction details, as this is a 'fun' thing :)
457 had 1rpm. 343 had 1.5 to 2 rpm.
For fire, the 343 serve as guides to the 457.

Gotta love these crazy designs!
These remind me of the Ontos tank destroyer with a 50cal gun to spot the 106mm recoilless rifles. I wonder if it would be better to have the 13.5in and the 18in guns on the same turret (triple with 18 in middle) and to make sure that the ballistic characteristics of the guns and shells where as similar as possible. Also reminds me of the N-verse 2.0 destroyer designs I was considering with 18in dynamite guns instead of torpedo tubes.
I would only armor against 13.5in, but then again I'm a battlecruiser speed is armor fanboy.

Gotta love these crazy designs!
These remind me of the Ontos tank destroyer with a 50cal gun to spot the 106mm recoilless rifles.

it is fun, and this is a good place for them.
In my ...Italian? set up, I had 3000 ton ships with a 10" spinal mount gun and a ram, inspired by the dynamite ships- the idea is you charge and fire as you go.
With these, fire control becomes the key to effectiveness.
There doesn't seem to be one book saying "This is what is needed" so I extrapolate from other readings.
Basically, 3 shells at a time were the minimum for a range ladder, but was not as good as 4 at a time - the extra shell splash made a difference.
But with 1 sleeve for all the barrels either you need separate turrets with different elevations, or a pause to change elevation between shots.
...or individually sleeved guns
Smaller guns made smaller shell splashes, which apparently were not readily visible at great distances. I don't have a good number for shell splash heights by shell size, but I'm inclined to think using the bore in CM as the spotting range in KM is appropriate.
Toss in two factors
- edge of seeing the whole opposing ship is about 18KM. (going off memory?) After which spotting by splash is harder, as you can't see the hull/base.
- edge of seeing the mast tops is like 22km (?), after which spotting by shell doesn't work at all.
- then you go to aerial spotting.
But for 1915, the 18km range is what's on the 'idea' of possible good battle range.
So the use of the 19cm guns works for quite some time, and the 25cm would work for all expected ranges.
The 345mm would not only be good for the splashes but also hurt if they hit.
I have problems with the speed is armor concept.
My early ships were 'fast' based on the juen Ecole idea, and yet a couple years later are 'slow' because of advances.
Right now, my large ships are slow but heavily armed/armored, while the lighter forces are fairly fast.
I may yet build some BCs. My trial designs are named after Steppe nomads - Scythians, Mongols, Timur (Tamberlane), Cimmerians, Huns.
I could install 2 x457/40 in a turret.

That is a rather formidable vessel.
Give the Parthians bad dreams.
I can see you're experimenting off a base design, so there are little clean up details.
But overall, that is sufficient number of 18" guns to merit consideration of how to defeat them.
With 1915, it would lay down the same year as the
Baphumet class, so it would be my 1919 ships that would be the "reply"...and I don't have those.
A lot of what I build will be contingent on what others do, so I have explored lots of options, but rarely that far forward in time.
But it is interesting to consider what
Justinianus would be like against a
Baphumet or a
Sealord or a
Scythian and all their variants. NONE of mine have 18" guns. :)
The
Justinianus would be quite a conundrum.
Question - you have 1 armor deck, which is too thick for the period, and would mean the upper belt uncapped by armor, or is that to be 2 armored decks, one 70-75mm and one 30-25mm ?
One advantage of 'slow' is internal volume is good, so it is very good at damage absorption.

I realize you are just having fun , I am having fun looking at them :)
Right now the Parthians are likely to stick to their 365m bore, right now it's the largest and no reason to upscale. When you produce 380mm, that is only a little larger.
Your
Imperator class will laydown as my
Taimat class finishes construction. I want to build at least two
Baphumet class, so how your
Imperator class looks will probably most effect if I build two
Sealord-style faster battleships or
Scythian-style battlecruisers.

Now that's a proper pocket battleship. That armament will put some serious holes into anything short of a capital ship.
It's a neat little vessel, I have some designs like.
AND it will defeat my protected cruisers, which have 180mm guns.

Now that's a proper pocket battleship. That armament will put some serious holes into anything short of a capital ship.
But this isn't the post Treaty era of 8" cruisers.
There are a number of Capital Ships...which are armored cruisers.
Both Byzantium and Parthia (and others) have for years fielded Armored Cruisers with 10" and 9" guns.
Outside of about 10km, the last several Parthian and Byzantine AC Classes are armored to stop 10".
Meanwhile the 120mm belt is too thin to stop their 9 and 10" shells from any range.
So good ship - yes
pocket BB - no
:)
QuoteByzantine Empire built an harbor in Diego Suarez with a 125m upkeep shipyard.
I have been very slowly building drydocks, but for the modest goal of supporting MTB squadrons.

I know that armor is thin.
I rework my 1913-1915 Building Plan about cruisers.
I have noted 2 x 7950t AC7. So, from 6000t to 7950t, I have some BP reserve...
21kts Battleships line need scout cruisers, the last 6000t (6x191+6x102-26kts) were built from 1905 to 1907.

I still think it is interesting the ways in which - while not planned that way -each of our pre-build fleets could be viewed as competing powers.
We both have 6000 ton cruisers, with often 6 x 180 or 191 guns.
My battleline is 20knots, yours is 21.
My armored cruisers look like reasonable "responses" to your armored cruisers - with Byzantium leading the way.
The result is the last 8 we produced, mine are 4x9.2 vs your 4x10", then my 4x10" and your 8x10", then my 8x 10"...
of course now you are building "armored cruisers" larger than my existing dreadnaughts.
Quote...of course now you are building "armored cruisers" larger than my existing dreadnaughts.
...
Eupatoria (28500t) were built in response to
Wicklow (26676t) from the Northern Kingdom. Building a powerful battle cruiser was very tempting.
In fact, it was a mistake. The probability of a
Wicklow vs
Eupatoria battle is very low. It would have been desirable to build 2 other
Ramses II BBs (26000t) instead and much more useful at the battle line.
Eupatoria will remain secret and will be based in the Black Sea.
The officially declared characteristics will be 27000t - 27 kts and 3T3x343
I've got a story item written up of the Parthians trying to figure out what it is by the general dimensions it takes up on the ways. But they won't know what the Byzantines built for quite some time. The Northern BCs are quite interesting. Walter has really built a powerful Navy. From a War-fighting point of view, he should be able to close off the Atlantic to Vilnus, and do well against Rome.

Quote...The 234mm turrets recovered from the Barbarossa class will not be used on the next 6000t scout cruisers, they will be scrapped...
Not sure ... the "economic" cruiser built soon with these turrets could receive, during the 10yo major refit, T2x8 "cal 50 of the County class.

The "birth" of the Japanese fleet changed the game
Byzantium needs more cheap colonial cruisers
The Parthians had a need for more cruisers, but the type I planned in 1911 got delayed until 1913.
But yes, this is one reason to provide a little bit more info on the NPCs. We may not know numbers, but if we know classes we'll have an idea.

A nasty surprise for any older cruiser one might find in a colonial setting. Not sure I would be happy with 26knts with the number of faster Large Armored Cruisers being completed, but its enough to chase down old VTE cruisers. Presume this is going to be plodding around the Indian Ocean and Indonesia rather than the Med?

That is one big scout cruiser...
I'll make the observation - you have guns over 210mm, that means capital ship architecture, that means the hull strength needs to be 1.00

If I understand correctly, these cruisers weighing less than 7000 t, with 234 must be built like battleships !!!
So the 2 AC6 of 6675t that I just finished
Foros & Fatsa are also out of rules !!!
Yeah, I had to scrap the plans for my 3,000t coastal defense ships for the same reason. You could regun them with 210mm or less guns and save quite a bit of tonnage.
AC6-AC7-AC8 are out :'(
Finally, they will be even better !!!

How much does it take to get both designs and additional 2knts of speed? I think they are both a little slow.
QuoteHow much does it take to get both designs and additional 2knts of speed? I think they are both a little slow.
27 kts Scout cruiser (SC 5) is designed to scout the battleship battle line (21 kts - 343 guns), engage its fellows (234 & 152 guns) and support the Destroyers (152 & 102 guns) in their torpedo attacks.
- The different ACs presented (AC6 - AC7 - AC8) are designed to operate in the colonies with the support of the rebuild battleships of the
Barbarossa class. The "sudden birth" of China and Japan in our game, imposes on the Byzantine Empire a larger presence of a combat fleet cruisers in the Indian Ocean and Australia.
The Byzantine Empire must have 2 fleets:
The Marmara Fleet with the 1st rank battleships battle line & the Colonial Fleet, based mainly in Diego Suarez, to keep the Asian Fleets in check, with powerful combat cruisers (24kts - 254 & 234 guns).
Note that these 24kts ACs can be rebuilt around 1925-27 with turrets of the (OTL) County class and their speeds increased to 27kts.
If the Chinese and Japanese Fleets existed when the Game was created, I would have built fewer Destroyers & Torpedo Boats and more (21-24kts) Combat Cruisers.
On the plus side you might not have to worry much longer about the Japanese and Chinese fleets...

Jef, is there a list of all the Naval guns that you have researched somewhere?
No list
I use historical English guns/turrets.
for AC7 :
http://www.navweaps.com/Weapons/WNBR_10-45_mk6-7.php
Note, this 254 guns/turret was used on AC3 Ceyhan class & AC4 Damas class
My understanding is there needs to be a list so what was payed for can be verified.

I had started an Excel board ... but I didn't finish it :-\

For the pregame, we could use either our "own" guns, or historical guns.
So I have the 1879 Gardner hand cranked machine gun. Fun, reliable, decent ROF, heavy....
So posting that you are using the English guns.. that should be acceptable for pregame.
Now that we are 'in game' the Gun Research system needs to be used to design new guns.
So a new 15"/42 is possible, but time and $ has to be spent researching it.
This also goes for Turrets/ Mounts, etc.
Shell weight is limited to the default of the longest caliber your tech allows for that gun.
I will also make the point again - older turrets/mountings, especially prior to the 1905 technology, are not as effective.

I know that ;)
QE 15/42 & 76,2 AA Vickers are in my 1912H1 report research...
Have a look now in Byzantine Artillery ;)

Nice table.
I need to learn to do that.
There is an old formatting tool somewhere on the forum. Put excel table in, get HTML table out. Likely buried in the N3 archives.

Well, it's pretty good firepower for its size, although the layout isn't great.

Gotcha.
Are you going to work your way up to that 1936 design with the carrier-style superstructure and wide turret arcs?

Cant say Im a huge fan of the design, but I've been focusing speed rather than range for my DDs. This design looses about two knots on the 1910 F-class (https://www.navalism.org/index.php/topic,7301.0.html), and trades it for range longer than most every Roman capital ship. I would wonder what the design looks like with closer to 30.5knts so its within striking distance of ships it could be expected to run into in the Med.
You need 2.5 t for Fire control, not 25t,
while short range wireless is automatic New construction laid down 1/1/10 or later does not require weight to be set aside for one (1) short-ranged set.
So you could probably have LR wireless (25t) and Fire Control (3t) and 7t to spare.
From the Parthian view point it's a bit alarming.
1/3 bigger than our Pirate class, about the same speed and armament, more torpedoes and longer ranged.
The idea of even more speed..at this time seems unneeded.
This, or our DDs, can sprint away from anything larger.
Parthia needs to work on it's torpedoes and destroyers. We are lagging.
I will note the E-Type lacks fire control.
Plus while 3000nm works in the North Sea/Med/Carrib the Romans are in,
for Parthia that is entirely too short a range for what we want to achieve. Our bases are every 2000nm, so we want to be able to go twice that in case one falls. Then we have a reserve.
Roman ships in general are going to be getting much longer legs now that the requirement of needing to shift across the Atlantic and fight is more serious considering there will be more modern Aztec capital ships than anticipated. Thats already kinda starting with the various 1913 designs, and will definitely be present in the planed H (replacement for old designs, 750-1000t) and I class (1500t bigboi) destroyers in 1914.

Yeah, working on the Aztec comes shortly after all the other stuff. Given the local opposition pre-1910 and their interest sphere, I'm inclined more towards a coastal BB, with cruiser & TB force, but I may give the task of picking old classes to a player.

By my math, any 15L42 would only be able to be put into a design in 1914H1, if the 1910 gun tech which allows such a design was started in 1910, rushed in four halfs, and then the gun research itself wold take two years starting in 1912H1. So the laydown date of that design would need to be at least 1914, if not 1915. When did Byzantium complete the 1910 gun tech?
Looking at the HY1, 1912 turn sheet,
Jefgte started the 1910 Artillery in 1910, in HY1 1912 he was at 5/6
Research started on the 15"/42, it looks like HY2, 1911.
The 14.01-16"/40.1-45 is the 1910 tech.
Until you finish the 1910 tech, you may not start gun research for it.
The 15/42 is under the 1910 tech, which is not done, so that gun can not be researched until 1913.
Research takes 4 HY, and so the gun can be used HY 1, 1915.
Gun Research :
Jefgte is paying a great deal extra for his gun research, charging himself $6, instead of letting the spreadsheet calculate it.
Honest mistake, that would be the cost of Tech research, but this is gun research and cheaper.
Jefgte, you have your 76mm and the 381mm in the wrong places.
The 381 should be where you have the 76mm spot.
if you type 381 below "Gun Bore >210.00" in cell C34, you will see the total cost is only $2, not $6.
You will have to copy the formula from C34 to C33, and E43 to E42 and E41
But
The International Expert Office "Kaiser & Snip" has expressed reservations about the realization in 1913 of the double turret of 381/42 and the laid down of the 29300t battleships of the Imperator class. Technology is not mature. Consequently, the Byzantine Admiralty decided to postpone the placing of these ships to 1915.
2 battleships were nevertheless planned in 1913.
Instead, 2 other 26000t battleships of the Ramses II class could be built with more modern lighter machinery and greater autonomy.

2 battleships were nevertheless planned in 1913.
Instead, 2 other 26000t battleships of the Ramses II class could be built with more modern lighter machinery and greater autonomy.
Justinien - Sélim I, Byzantine Empire - 1913 BB5- Ramses II class laid down 1913
Displacement:
25 850 t light; 27 458 t standard; 29 782 t normal; 31 641 t full load
Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
(623,36 ft / 623,36 ft) x 100,00 ft x (26,71 / 28,11 ft)
(190,00 m / 190,00 m) x 30,48 m x (8,14 / 8,57 m)
- Torpedo Bulkhead - Additional damage containing bulkheads:
1,07" / 27 mm 406,00 ft / 123,75 m 24,71 ft / 7,53 m
Beam between torpedo bulkheads 92,00 ft / 28,04 m
Misc weight:
24t for 4 sub TT x 21'' with 4 reloads.
Practical considerations.
27mm armored bulkhead - compared to the historical range, on the lower end of the range.
1.24m wide TDS - As a engineering matter, your Naval Design staff will say this should be doubled, or more.
Information:
Underwater tubes : after about 20knots, not practical to use. The ship can slow from 21knts to 20knts easily enough, so workable here.
Quote...27mm armored bulkhead - compared to the historical range, on the lower end of the range...
That's a bullet
40mm is the curent TDS for Byzantine BBs
1,07" => 1,57"
----------------------
This 25850t class is too heavy. a lighter class 20 000t must be certainly built.
Byzantine need more Expansion/air points...

QuoteByzantine need more (scout) cruisers
2x10000t with 3T2x254 -27kts is too heavy
2x3800t with 6x152+6x120-27kts is too light
cost 27.600 BP & $
I rework the old project of the "Heavy" Scout Cruiser with the reformed 234mm turrets of the Barbarossa class
=> 6840t with 2T2x234+8x152+6x102-27kts
Real cost 6.288 BP & $
x4 cruisers = 25.152 BP & $
This heavy scout cruiser is not a good choice, old T2x234 could be used on colonial cruisers.
Finaly, the last 6000t SC4 class is update with the classic Byzantine 6x191 + 6x120 vs destroyers, better armor, 27kts to screen battleships & long range.
More economical:
21.260$ & BP for 4 cruisers.

Destroyers have over 50% of engine displacement, often 52, 53, or 54%...
TGBs have only 50% of the displacement reserved for the engines.
Weight saving is reserved for the installation of a powerful artillery, often 120mm guns and 4 torpedo tubes.
The first TGBs were built in 1892 with a speed of 21kts, sufficient at the time. The most recent show 28 or 29 kts.
In 1915, The Byzantine Empire confirmed this concept and the missions for the next TGBs.
1 - Colonial works, patrols, escorts...
2 - Close protection of large combat ships vs Destroyers and MTBs.
3 - Scouting & reinforcement of the combat fleet.

They will replace the 48 TGBs of 500t - 21kts all currently working in colonies. 4x120mm - 27kts will be useful to serve in a squadron as a reinforcement of the fleet.
I considered the 16 / 18kts monitor, cutters and sloop as BP spent unnecessarily because very little usable in wartime.

Heh. It can be tough to craft an effective unit at that size.
I'm sticking to a limit of 5.5 meters deep draft, but I could go longer than I have.
While I'd like to be able to use a 120m dock, I have 150s/160s as well.

The cost to update the 12 x75m shipyards to 80m is 6$ & 0.6BP
Only AA guns?
I've got to bump up the size of my largest docks to accommodate the next generation of Union capital ships but beyond that I'm not in too bad a shape for dock length.
QuoteOnly AA guns?
It is a dual use gun.
http://www.navweaps.com/Weapons/WNBR_3-45_mk1.php
Would need to be in a traditional mounting, there are no DP guns until much later based on the rules. The current design would, IMO, only be capable of firing on flying targets with the 3" battery under fire control, the guns would be in local control if anything for surface targets. Also, the generation of fire control needs to be noted.
QuoteThe cost to update the 12 x75m shipyards to 80m is 6$ & 0.6BP
Note that 80m shipyards are better to built 1000t oceanic submarines.
QuoteWould need to be in a traditional mounting, there are no DP guns until much later based on the rules. The current design would, IMO, only be capable of firing on flying targets with the 3" battery under fire control, the guns would be in local control if anything for surface targets. Also, the generation of fire control needs to be noted.
In 1915, rangefinder was carried out only for shots against ships. AA shooting is done ... by eye.
Regarding the Byzantine ships with 3 "AA in 1915, it is to shoot against the Zeppelins. Turkey shooting is too far away ;D

While I get the the idea of a 6in armed dd leader, I think that like the germans when they tried it, it's just a bit much on the shell size to be useful. To ask, could you get a 5th mount on if you went for 5in guns? I just think that while the weight of each shot will be telling, the relative loss in rate of fire will hurt you more in a destroyer battle. Unless you're going for something on a dd hull that's meant to tangle with cruisers.....in which case I have my doubts that it'll be super effective, but ultimately I might wind up in the same position due to budget constraints.

It's also a very small cruiser scout ...
The performance will also be very small.
=> I have the choice for 1916/1917, I can easily go up to 3900t or even far beyond ... a
HMS Hood class is even possible. It will be a cruiser series with 152 or 191, 234, 305, 343, 381 ...
Currently, I am also thinking of standard economical 30/32kts Cruiser (ala Panzerschiff) to be mass produced. They will constitute an excellent escort for future CVs.

That SC is a nasty customer at 32knts. I wonder if the 120s are a little to heavy compared to the 152s to be useful. Can you recast the design with 8x152 in 3(2)----3?
The SC is interesting.
I am guessing it's exploring the cost/benefits of speed.
The triple 152mm (which should be QF, not breechloading) are weight saving, but means the armament is 3 guns/fore aft.
The 0.45 BC ... that seems low for a 9000ton cruiser, but she's quite beamy so not really an issue, just tapers rapidly at the ends
Overall, from the Parthian Point of View, it would be a tough match for my 'Raiding Cruisers',
but as they have much heavier armament they should prevail.
From the scouting point of view, the Shamshir class I put up looks to be the closest adversary.
It's 2/3rds the size, 1 knot slower, same 6 gun broadside,
less armor, but with 165mm not 152mm, so the two vessels are probably vulnerable at roughly
the same ranges.

In the continuity of the last Byzantine class cruisers:

AC8 class -
Harad - 1914 - 6950t - 2T2x234+10x152 - 27kts
Here is => SC6 class - 1916 - 6950t - 3T2x191+6x120 - 30kts (32kts is too expensive)
=> Same speed as Parthian Raiders. ;)

For Byzantium, the battleship line speed is 21-22 kts. (Jellicoe)
I prefer to have a few big cruisers with 305 and 343 for lighting and raids (Beatty). It is a short-lived situation. No G3, Hood or Lexington.
I prefer very strong battleships like super QE with 5T2x380 or super Rodney with 4T3x406. 21-24kts
However, if my neighbors already spend 30kts for battleships ...
I may stay at 22-24kts. Battleships having to act like a steamroller and destroy everything in front of them.
Which one was the strongest? HMS Hood or USS Tennessee?
I think the most suitable strategic and tactical configuration is Jellicoe & Beatty.

No superfiring turret? So is layout AB/Y with "A" and "B" back to back or is it A/Q/Y?

Battleship Treaty
The danger with 343 guns on a small BC hull is to see it reclassified as a battleship.
Having new 16800t battleships doesn't really satisfy me :-[
Byzance didn't built this kind of BC with 343 guns
QuoteFor Byzantium, the battleship line speed is 21-22 kts. (Jellicoe)
I prefer to have a few big cruisers with 305 and 343 for lighting and raids (Beatty). It is a short-lived situation. No G3, Hood or Lexington.
I prefer very strong battleships like super QE with 5T2x380 or super Rodney with 4T3x406. 21-24kts
However, if my neighbors already spend 30kts for battleships ...
I may stay at 22-24kts. Battleships having to act like a steamroller and destroy everything in front of them.
Which one was the strongest? HMS Hood or USS Tennessee?

You need to make sure that your Torpedo Bulkhead type is always Additional Bulkheads. There is an error in the way Springsharp handles the Strengthened Structural option that makes it unsuitable for our use.
Super Rodney has an error with the secondary layout.

I just hold doubts as to the effectiveness of the upper belt. 5in of armor is barely going to resist cruiser or secondary fire at battle ranges. It's going to do little more than initiate heavy caliber shells and set them off inside the ship. Rather than having 4m of 5in plating overtop of 3.5m of main belt, I'd think the tonnage would be better served making a taller main belt in the first place.

Quote from: TacCovert4 on January 26, 2021, 04:30:54 PM
I just hold doubts as to the effectiveness of the upper belt. 5in of armor is barely going to resist cruiser or secondary fire at battle ranges. It's going to do little more than initiate heavy caliber shells and set them off inside the ship. Rather than having 4m of 5in plating overtop of 3.5m of main belt, I'd think the tonnage would be better served making a taller main belt in the first place.
That depends on the "Battle Range".
If the current 14km of tech is used... you would need a turreted weapon in the 200mm+ range.
However, battles are likely to be "in" ranges you can hit things, so say 10km.....there it stops the Parthian 180L43, not by much, but it does.
Still, every Quickfire gun will fail to penetrate 120mm down to ~8000m.
The question then becomes if that's worth the investment.
I will make the general observation that when you have fewer than 4 guns in a salvo, it is somewhat harder to make and keep the fire control solution.
"Overs" are hard to see due to the ship's superstructure and funnel smoke. "Hits" can be basically invisible, so what I've read is optimal is to get 2 shorts - very visible, and countable, then the 3rd shell hits, and the 4th is an over.
To do that, with allowances for handling errors, is one reason the Brits liked 5 -gun salvos - one not be available to fire, and you would still get your 4 shell ladder.
That said, we had accurate 6 gun ships, and hits from forward 4 gun salvos.
So it's a consideration, but not an overwhelming one.

Tone style layout? That is a very heavy AA armament and no anti-MTB guns. I do like how it keeps a heavy secondary.
Ya, that AA battery is way to heavy given what planes have actualy done to ships so far, nothing.
Quote...That is a very heavy AA armament and no anti-MTB guns...
381 vs BB & Cruiser & DD & MTB
191 vs BB & Cruiser & DD & MTB
120 vs DD & MTB
76,2 vs DD & MTB
The selection of the guns targets depends on the circumstances and the most threatening ships, obviously.
Given the 120s and 76s are AA guns, I wouldnt count on them being effective anit-surface weapons.
Well they're going to be operating over open sights without effective FC. So, decent against MTBs as those, especially the small ones, make FC a pain. But I wouldn't want to rely on no-FC guns to fight DDs, and the 191s are such overkill for even 1500t DDs that it seems like the 'huge AA battery' really isn't worth it.
I'd go with the 120s as a Tertiary battery if you want to keep the intermediate firepower 191s. And then the 76s as AA guns.
The heavy secondary is an interesting twist on things.
Agree with Tac on the lighter batteries.
Quote...Given the 120s and 76s are AA guns..
120 are not AA guns but QF...This is a bullet ???
=> Corrected
Byzantium uses since 1900 on battleships, 191s as secondary artillery to support the main artillery and to engage enemy cruisers.
However, in some situations these guns can fire at smaller targets, DDs or MTBs.
120s are commonly mounted on Destroyers and TGBs. Their job is therefore to fight against DDs and MTBs.
Following the instructions of Grand Admiral Izmar, Commander of the Byzantine Fleet.
"A battery of guns must engage an enemy as soon as it is within firing range. No reproach will be made to the Gunnery Officer if he fires at an enemy ship. However, he may be criticized for not having firing on the enemy ship designated by the Firing Director."

2 Things:
1) If you're doing 18in TT (450mm), then you only need 2 tons per torpedo/tube. So you could add an additional 2 torpedoes. Or you can upgrade the torps to 21in (533mm) units.
2) I see you have a 76mm breech-loading gun. Is this supposed to be some sort of old gun, or is this a typo on an AA mount?

From Kaiser
QuoteAs a storyline matter I want more "coast guard" gunboat type ships to patrol my extremely extensive coastlines.
The new Aux patrol sloops will fit nicely in that part of the concept, but are rather light on the gun batteries.
I also want something with "gunboat" in the look, which could credibly be providing needed force if
the new members of the Parthian Empire need further persuading, something needs to back up the Marines.
Alternately, credibly be stopping piracy, slavery etc where they may shoot back.
Byzantine answer
QuoteHowever, ocean-going vessels with respectable performance are needed.
DE or TGB concept is relevant. Byzantium must also replace 500t TGBs built in 1892.
