At the end of 1917, new rebuilt Colonial BB Drasty & Niebez are going to join the 5th & 6th battle squadron (Diego Suarez & Port Darwin)
replacing AC Foros & Fatsa.
Then, as early noted, speed of Foros & Fatsa could be update to 27kts with new engines.
1911 engines from these cruisers could be used in 2 new Seaplane Transports.
But, I have doubts about the feasibility of dismantling the machines and reassembling them without problems(?)

1911 engines from these cruisers could be used in 2 new Seaplane Transports.
But, I have doubts about the feasibility of dismantling the machines and reassembling them without problems(?)
Short Answer: I think we can allow it to work without 'bonus' problems.
Long Answer :
Two issues :
1) Specific Question : Is it reasonable to dismantle and reuse such large machinery as engines?
I do not know of it occurring.
That period of steam engine was used extensively in my area for logging and so I've seen a number of boilers and they are riveted, not bolted.
So I would assume the machinery is in large pieces and hard to move.
This type of work allows you to alter the armor deck, therefore you are removing chunks of ships down to the armor deck
The cutting torch was invented in 1903, and would be the presumed how you remove ship parts.
So, it probably would be an additional cost to
not cut it into small chunks.
Do we want to make a rule for these subcases? and then try to track that the player has properly applied the extra cost?
I would say no.
So we will "Hand wave" that once you get down to armor deck level, and open that up, you cut the machineries attachment points to the ship, and use cranes to take them out in large pieces which can be reusable.
2) The overall question of if equipment removed from one vessel can be used on another is not specifically addressed in the Rules.
The question then is : IF there is no provision FOR it, IS it is not allowed ?
I have noticed some players do it.
I do not see a rule that clearly disallows it.
I do not see a reason to disallow it.
It's a nice storyline issue, but does not give great advantage.
All the "equipment" is paid for and so free.
So long as they are willing to track the removed equipment on their turn sheets until they are reused,
That way it is clear what is occurring, and trackable, but not required for participation.
As such it does not raise the minimum effort for other players or moderators.
In 1914, I have built 2 MTB Transports and I have in project, for 1918, 2 Sub tenders, all with the mercantile rules.
For the Sea Plane Transports, I will also build them in 1918, with the mercantile rules.
It's more logical and simpler.
The engines of the AC Foros & Fatsa will be changed to increase the speed to 27kts, as planned when they were built in 1911. They could thus become Heavy Scout Cruisers.
Old engines will be scrapped.

That is a stout cruiser.
QuoteThat is a stout cruiser.
Byzantium thinks the Parthians are the most likely opponent.
Parthians use 165 and 180 guns on these scout cruisers.
Byzantium uses the 191 and 120 guns on these scout cruisers.
Guns technology "United Kingdom".
For the first time, 191 and 120 twin turrets are available.
To be within the 6000t limit, 3T2x191 are placed "centreline evenly spread".
2T2x120, superfiring to T2x191 fore & aft.
Byzantine scout cruisers make 27kts or 29kts for scouting 21kts divisions of battleships.
Oh I wasn't insulting it in the least. In fact it'll be quite a match for the Weapon class, despite not being designed as a direct counter. It's a solid 'Frigate' cruiser, by Aztec parlance.
Rework Antalya seaplane transport class
These seaplane transports are also intended for working with battleships squadrons.
The role of seaplanes on land and on board is to locate and provide informations on enemy forces and their movements.
Assistance in adjusting shots.
Hunt enemy aerial reconnaissance.

with the Battleships Squadrons, I must paid in full...
But you're calculating off the normal displacement instead of the light displacement?
QuoteBut you're calculating off the normal displacement instead of the light displacement?
From rules:
Mercantile Standards/Auxiliaries
"A ship in government service may be built to mercantile standards if armament and armor take up no more than
2% of the ship's weight at normal displacement. Such ships could include colliers, transports, survey ships, and others..."
OK , I misread rules. :-[
Distribution of weights according to SS2 is done with normal displacement, so thats what I've been using since it comes with a handy percentage already included.
Maybe that adjusts my work on ASW ships a bit.
So does the title of this thread mean there will be no Byzantine Empire after 1924?

Oh I wasn't insulting it in the least. In fact it'll be quite a match for the Weapon class, despite not being designed as a direct counter. It's a solid 'Frigate' cruiser, by Aztec parlance.
Jefgte has an annoying tendency to make tough ships.
The last..10? Parthian cruisers are 8x165mm, while the preceding had 10x165mm. These Byzantine ships have comparable speed and armor and bigger guns. I'd have to go back to the Saka & Margaetae 180mm raider cruisers to really counter. So fielding these might lead to a Parthian reaction...like the
Capharact light armored cruisers I've designed so many variations on.
but..this one has a flaw.
Sorry Jefgte,
this ship has turrets, and so needs 1.0 hull.
"Cruiser Architecture: For all years, Cruisers with turrets shall have a composite hull strength > 1.0."
On the other hand, you don't need to stick to 6000 tons as a result.
Due to weights, turrets are indeed likely necessary for the twin 191mm to be useful.

Yep thats what it says.
Don't know why that one rule specifies normal and most others light....but that's what it is.

So fielding these might lead to a Parthian reaction...like theCapharact light armored cruisers I've designed so many variations on.
The 165mm and 180mm are greater than the 6 ". If the Parthians had used the classic 6" for these SCs, the Byzantines would also have installed the 6 ".
Byzantines use the British guns 4", 4"7, 6", 7"5 ...
6x7"5 is the max for 6000t SC.
Byzantium thinks that 6x7"5 are equivalent to 8x165 & slightly less than 8x180.
Well, even if the ship is 7000 tons after correcting the 0.9 comp hull issue,
the 6x 7.5" may well be worthwhile
Armor Penetration :
The 191mm has better penetration, but the 165mm somewhat faster ROF. Neither can penetrate the vitals of the others outside ~10,000m, where the Parthian ROF will matter, but the Byzantine will be able to penetrate sooner.
I will point out the "other gunhouse" of 20mm on the Byzantine turrets will only stop splinters up to 120mm guns, while the barbettes are vulnerable to the 165mm out to 14,000m - current FC range.
Under Parthia's Naval Artillery, I list the penetration expected from different Parthian guns at various ranges using Logi's Ballistics tool.
Originally that was for my own use, and I expected whomever the moderator was would use their own chart / tool.
Since that task fell to me, that's the system I use for generating custom gun penetrations.

I like it.
I like it, it's well balanced.
However, I do have some concerns. The speed is going to be low enough that this DD would have a hard time escaping from some cruisers already in service in 1917, much less contemporary destroyers. And then the weapons mix is sort of 'neither fish nor fowl'. 6 TTs is solid for a 'gun destroyer', but the gun firepower is going to be a bit on the weak side even when compared to contemporary 1000t DDs.
It's just fine for colonial sloop work or general patrol work. But I do feel that this class will be very quickly rendered obsolete and vulnerable to all of its contemporaries.

I agree, next TGB700 is made for colonial works, patrols, escort & Capital Ships protection.
This 700t TGB is more economical that the first 1000t DD.

Yeah, This 700t DD would probably be able to go toe to toe with the 1000t DD in a gunfight by virtue of the bigger guns.
I might suggest working 4x120 into your 1000t DD to give it the firepower to match with contemporary DDs.

For a 79.8m Patrol Boat/DE build in an 80m shipyard, I am more interested with a long range wireless than an extra gun. Add 25t is huge when all the guns are already 44t ...
OTL => DE have lower firepower than DD.

I think it comes down to what you want to do with it. 3 x 120 is sufficient, but will suffer against the larger fleet destroyers that'll be laid down concurrently or even some already in service. 4 x 120 will make a better fleet destroyer, but the lack of LR wireless may hamper colonial duties as the ship will rely on relays from ashore radio stations.

Looking Byzantine Fleet Management =>
500t TGBs - 1897-98-99 assigned to the colonies will be replaced by 500t DDs of class D3 - 1901-02 (24ships).
500t TGBs - 1897-98-99 => scrapp
Class TGB900t from 1918 is suspended.
More D9 - 1140t DDs built.
So after all that planning, you're scrapping the idea?
QuoteSo after all that planning, you're scrapping the idea?
Yes, I am giving up on the idea.
In 1917, Navies build destroyers from 1000t to 1500t (30kts).
Byzantium can no longer take 500t destroyers as sufficiently fast and powerful ships.
They are therefore downgraded to colonial patrol boats or coastal torpedo boats.
The 500t (21kts) TGBs from 1897-98-99 will soon be scrapped.
They will be replaced, for the colonial works, by 500t Torpedo Boats (25kts)1901-02-04.
=>
In the 1918 classification, the DDs must do at least 750t.
That give for Byzance:
- 51 DDs from 750t to 1140t
- 81 TBs from 400 to 600t.

QuoteJefgte has an annoying tendency to make tough ships.
The last..10? Parthian cruisers are 8x165mm, while the preceding had 10x165mm. These Byzantine ships have comparable speed and armor and bigger guns. I'd have to go back to the Saka & Margaetae 180mm raider cruisers to really counter. So fielding these might lead to a Parthian reaction...like theCapharact light armored cruisers I've designed so many variations on.
but..this one has a flaw.
Sorry Jefgte,
this ship has turrets, and so needs 1.0 hull.
"Cruiser Architecture: For all years, Cruisers with turrets shall have a composite hull strength > 1.0."
On the other hand, you don't need to stick to 6000 tons as a result.
Due to weights, turrets are indeed likely necessary for the twin 191mm to be useful.
I think destroyers equipped with 2T2x102 or 2T2x120

Actually that's a twin mount. Just like the 5in/38 twin. Mount and hoist. Even the US 8in mounts on Pensacola weren't turrets. It was a weakness at that size, but it was a weight saving option. Hence my 180 twin is a mount and hoist with additional power assist instead of a turret so I can get by without needing turrets on my weapon class cruisers.
"Cruisers, always more cruisers"
Byzantium has 16 scout cruisers with a speed from 26 to 29kts. 2 others, C6 class were laid down in 1918.
They are very similar to the C5 class (5315t - 6x191+6x120 and 27kts).
Differences relate to the arrangement of the (classic) 6 x 191 arranged at the ends (ABC) (XYZ) B & X superfiring.
Speed also increased to 29kts, the range goes from 6500nm-12kts to 8000nm-12kts.

The aeronautical officers have requested a lengthening of the ships in order to be able to maneuver the SHORT 184 seaplanes more easily. The hull has received an additional 10m module.
This made it possible to increase store volumes.
The class increase from 5200t to 5550t.
=> Rework Antalya class Seaplanes Transport from 5200t to 5550t - LD1919
These seaplane transports are also intended for working with battleships squadrons.
The role of seaplanes on land and on board is to locate and provide informations on enemy forces and their movements.
Assistance in adjusting shots.
Hunt enemy aerial reconnaissance.

Do you not have the Heavyweight torpedoes? Or opting not to install them?
QuoteDo you not have the Heavyweight torpedoes? Or opting not to install them?
Difficult to install enough 4t TT on 1300-1500t with a salvoe provided.
Or it is necessary to reduce the armament or misc weight in reserve ...
Makes sense. The 4t torps are where the choices start to come in. Really a no-brainer to go to 21in torpedoes from 18in, except if you have a specific reason. But the regular 21in vs the Heavyweight (longer ranged) 21in torps is where it comes into question based on doctrine and expected use.

Looks like a very effective cruiser. Frigate in Aztec parlance. The gun armor is a shade on the flimsy side, but I guess you're banking more on that not getting regularly hit by shells at battle ranges unlike the belt.

I don't necessarily think you need to take speed up. 30kts is going to put it in that 'high' range band as it currently sits between 30 and 32 for cruisers. I'd probably look at increasing armor, probably by making the belt a little taller as it's pretty narrow. You've got a nasty punch with those guns, but they're also 'big' guns, so protecting them from hits is also probably a good idea, lest you wind up with a fire in the handling spaces. But it's definitely a 'cruiser to look out for'. The gun size makes it capable of squaring off with the Weapon class, though they have 3000t on them, and the armor and extra guns that comes with it. And they'll be a serious contender against my own next cruiser series. But overall, a dangerous ship......I'd probably use the tonnage to deepen that belt and give you more wiggle room for waterline hits.
Currently the standard armament of my scout cruisers is 6x191 & 6x120

These ships are going to be laid down.
I think they are in agreement with the new rules on seaplane transport.
Misc weight can be distributed differently...
Posted August 14,2021
The aeronautical officers have requested a lengthening of the ships in order to be able to maneuver the SHORT 184 seaplanes more easily. The hull has received an additional 10m module.
This made it possible to increase store volumes.
The class increase from 5200t to 5550t.
=> Rework Antalya class Seaplanes Transport from 5200t to 5550t - LD1919
These seaplane transports are also intended for working with battleships squadrons.
The role of seaplanes on land and on board is to locate and provide informations on enemy forces and their movements.
Assistance in adjusting shots.
Hunt enemy aerial reconnaissance.

The C7 class is intended to replace the old Byzantine 21kts cruisers.
12 x C7 class cruisers were planned from 1920 to 1923.
8 x 3950t cruisers deemed too weak (6x152) will be scrapped first. They will be followed by the 4 x AGB 5850 (2T2x191).
Atokos 8700t class, more powerful (10x191), will be replaced by a C8 class to be defined.
----------------------------------------------------------------------
5800t => 5900t I increase Main turrets armor to 140mm & barbettes to 100mm.
5900t => 6000t I increase Misc Weight for 60 minen.

I'm just a bit ambivalent about a pre-dread gun layout on a cruiser being built in the 20s. It's hurting its entire fire control setup at that point, though I see that it's for a very limited mission.
It's kind of "neither fish nor fowl" for me. Faster than I expect a gunboat/patrol unit to be, but under-armed for a cruiser.

I know it's heavier, but I like it more. As always, comparing it with my own ships, it would be a serious threat to my Jaguar class cruisers, and would give my weapon class a hard fight. Overall I think this is your winner there.

I'm just a bit ambivalent about a pre-dread gun layout on a cruiser being built in the 20s. It's hurting its entire fire control setup at that point, though I see that it's for a very limited mission.
I think one needs to consider the ROF available to lighter weapons.
You see mixed large/small guns on both British and French cruisers well after all-big-gun was adopted.
From my readings, the desire was to maintain a 4 shell splash ladder.
Optimally 2 short, 1 on, 1 over.
The overs were hard to see, the unders easy. and having the 'hit' be the #2 or #3 shell meant easy adjustment of the bracket. Then minimum was 3, desired as 2 unders, 1 on - sacrificing that harder to see over ... or under/on/over. But not as effective or flexible as 4 guns, and subject to feed issues delaying volleys.
This supposedly influenced the 10 gun large caliber ships, with the ability to fire 2 x 5 gun salvos. That 5th shell was ostensibly for 'slack' if there was a loading sequence issues and one gun could not fire on sequence.
With the Queen Elizabeths the RN decided those did not occur enough for that 5th turret to be critical.
However I think that may be why you see the 3+2 designs on Nevada and Teggethoff.
Later, improved optics, fire control computer and aerial spotting made smaller volleys less impaired.
But that's for big ships firing only 2 shells/barrel/min.
For a small ship, with ROF of 4-6+, you should be able to get the same splash spotting effect from just 4 barrels.
You still need the number of shells/volley to be minimum of 3 (2 unders and on) so a single 3-gun might work,
but 2 twins or 3 singles bearing should be dandy.
As for mixtures of guns, Seekrieg has a 'multiple ships at same target' which is a mild deduction, and I apply that to one ship with mixed battery
as well. It's not a huge deduction, but if you have a poor FC solution, it's not worth the mixed battery. Closer in, it becomes worth it again.
Which matches what the Germans at least intended with their 150mm secondaries. Of course most WW1 fights were beyond effective FC range anyhow.
As for the Byzantine ship. 27 knots puts her in the same speed bracket as my 1906 protected cruisers, with similar armanent & protection, on 3/4 the displacement.
That is pretty good.
One of the 'Dark horses' out there is the Ethiopian Navy. It's really not obvious, but there is a couple hundred thousand tons of NPC navy on Red Sea.
Byzantine has a large army, and so can directly threaten the Ethiopian homeland, making them reluctant to engage.
But maintaining cheaper but effective patrol units will 'storyline' allow continued deterrence to the Ethiopians becoming 'active'.
A possible rebuilt for C3 class...
Increase Forecastle height
Increase freeboard => reduce draught
Change VTE 18450shp to turbines 36000shp speed update to 27,15kts
Change 6x102 to 6x120
Increase belt from 70mm/2.74m to 100mm/3,9m
Add 2x76.2AA
Change 18" TT to 21" TT
Increase reserve weught +100t
=> Displacement decrease from 6000t to 5110t

Just to ask, you're building full up battleships and pocket ones? I presume this is more of a coastal bb? Only thing I don't like is half the main armament is in each turret, and the split means that you don't get the benefits of shallow angle broadside.
Otherwise it looks good. I had considered this for my own crash bb program after ironclad bay. But opted Otherwise. Overall I think this could be a concern for the monarch class if it has a numerical advantage. One on one I think it's still pretty vulnerable even with its heavy armor.
I feel like I'd trade that end belt for more protection on the quarterdeck, since the steering gear is under there somewhere.
Apart from sacrifices to the protection scheme, it's a pretty sturdy design, and certainly a challenge for anything else in its size range.
I will say the decks are kind of thin given how long the range is getting.
These are just SS tests to see what is possible to build with T3x381 and T3x343 in 1922.
Pockets can be a second line of battle (tactical) and hit heavy (870kg shells)
Pockets have the advantage of dividing the opponent's fire.
2x18,000t vs 1x36,000t.
The speed allows you to choose the combat distance (immunity).
The striking force is the same: 12x381 = 10440kg
Survivability is the same: 26360kg
I continue my SS.
Remember that all the TDS need to be Additional Damage Containing bulkheads. Strengthend structural is bugged

I like that balance of speed, armament and armor better; it would be annoying to deal with.

Project A, Byzantine Empire BB8 laid down 1922
I would suggest the main battery be 3-Gun, not Triple. There is a ROF increase.
The end belt does not quite reach.
I see some value to retaining the upper belt.
But the armor deck is only 80mm, with no provisions for an upper deck.
So the area protected is not fully protected.
As for Pocket Battleships,
you've already done some, but I wasn't expecting others.
Though your logic makes some sense.
Plus, more units give more flexibility.
The triple guns are again a minor flaw.
Laid down in 1922, they will be launched and start fitting out in 1924,
so that's when I could reasonably "learn" about them.

Project C, Byzantine Empire BB8 - Pocket Battleship laid down 1922
Displacement:
18 000 t light; 19 143 t standard; 20 482 t normal; 21 553 t full load
I was curious and checked my files last night.
I've had similar ships slated for builds starting 1913...but keep loosing out.
My version of these types was last updated Oct 7, 21 to a 1920 laydown.
19,000t - so we're close there.
I have 6 x 365L45, and 26 knots to match my
Stormbringer class.
Anyhow, if you do lay these down, I will have to dust off and update my designs :)

I guess my only question is, what do you want these to do long-term? For fending off cruisers or even 'razees', it's a bit much. For fighting any of the BBs aside from some first-gen dreadnoughts.....it's a bit weak. Are you looking to have a swarm of coastal defense ships and then a separate battle fleet and use these to economize on actual battleships?

To gun down the cruisers and to help the battleships in their jobs.

Absolutely valid.
These vessel types are one the Parthians are scratching their heads over. Back around 1913 we were looking at similar for coast defense battleships / pocket battleships.
I still have a design series I keep updating and tinkering with.
Edit : BTW, I note the Fire Control weight is off.

Handy in the anti-surface role, but no ASW capability?
QuoteHandy in the anti-surface role, but no ASW capability?
It's not an oversight, it's a voluntary choice
All I know is it is an interesting comparison to the 1920 500t Pesh-Kabz Torpedo boat leader I put up a while ago.
I managed 2x 90mm+1x57AA, you 3x 102mm.
I suppose the biggest difference is I have 1/2 knot more speed,
and that I have 2.5x the fuel, so I can make long runs at top speed.
I like that you got the % machinery down to 50.0,
I think if I tinker with mine I may manage a 3rd gun as well.
This Torpedo Boat class is intended for work in archipelagos, narrow seas and near harbors.
Egée Sea, Red Sea, around Madagascar, Timor Sea...
To maintain the tonnage at 500t and have a powerful surface armament, the ASW function has been sacrificed.
Submarines in 1920 did not represent a very serious threat.
ASW work is for biger TBs & DDs.

Pretty much what I was looking for in my Pesh-Kabr.
I wanted something that could be built in numbers for the 'green' waters,
but also a dedicated leader for MTBs on high speed runs.
I will have to find time to examine the reposted long range version,
figure out how to make my Pesh-Kabr better.
I studied (but not posted) in October 2021, the reconstruction of AC3 - 14860t - 25kts -

So you're adding bulges and replacing armor in a refurbishment, then?
QuoteSo you're adding bulges and replacing armor in a refurbishment, then?
Then, reconstruction is more expensive than refurbishment ...too expensive I think for an old hull & a second class BB.

I think it is not worth the expense, but that's me.

QuoteI think it is not worth the expense, but that's me.
It is difficult to increase the speed to 27kts without having poor seakeeping.
These reconstructions can be numerous in a colonial squadron near the BBs and face other 4000-5000t cruisers. They can serve another 10 to 12 years.
With these colonies in the Atlantic and in the Indian Ocean, Byzantium needs cruisers and GB in quantity... like most of us.
In 1921, Byzantium will have 44 cruisers:
- 20 squadron cruisers 24/29kts
- 16 of 21kts.
- 8 in reconstruction 24/27kts
Think I've got ~32 cruisers at the moment, not counting ACs/BCs, but my sealanes are a bit more compact than Byzantium's.
I have a grand total of 2 cruisers that are a) Can go at least 27kts, and b) Have at least 6" guns... I have an additional 10 than meet a) and 4 that meet b)
Looks at cruiser fleet.
Cries softly.
"At least all but five of mine are modern!"

The numbers look good but I'm skeptical about a triple 190mm on that hull.
It's the old 'how to evaluate BC' problem again.
The ship has the same beam, but is 1/3 longer than Vanamoinian
which had 2 T2 254...much heavier mounts
Jefgtes actually has a larger displacement.
Plus with 2 T3, they can be in "B" and "Y" where the beam is larger
so the hull girder better.
- I am looking for an economical 27kts -125m colonial cruiser.
- I could test 2T2x234.
- I don't like the 4920t, I prefer the 4600t.
- Or built more C7 - 5500t cruiser (?)
This one is well balanced, not too expensive for a colonial cruiser.

at 16m for the TDS, there are only 2m interior bulges on each side.
Depth from side effects how much energy hits the armored holding bulkhead.
A single 30mm holding bulkhead is likely to prove weak at that distance.
There is still value, and it should work against at least light torpedoes.
I have tried several versions of a similar vessel and get similar results.
I need the draft to be 5.5m or less so they can base out of Khasab, and interdict
the straits of Hormuz. I also want them to base in rivers and shallows
at Palembang, Medan, Orinoco, etc.
They will replace the now-scrapped 'Gatekeeper' and 'Keymaster'.
How much speed they need for that role,
and if a torpedo bulkhead is worthwhile, are two questions.
I forsee such ships as being targets for enemy torpedo craft,
which will have the draft needed to attack them.

I added the TDS on principle but without much certainty about their effectiveness.
These are small coastal vessels intended mainly for the Red Sea to replace the AGB5850 to weight in front of the Ethiopian Navy.
They will have to support the DDs, TBs & MTBs in the attacks.
Their artillery and armor are sufficient to engage heavy cruisers and support battleships.
I will SS 150m, 27kts version.
With 27kts & 5000nm range, she is nearly a cruiser, not a Coastal AGB.

Update AC9 to 11485t
2T3x254, Byzantine Empire AC9 laid down 1921
Isparta, Ispir, Ivgilu, Ivrudi
Displacement:
11 485 t light; 12 126 t standard; 13 157 t normal; 13 981 t full load
Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
(572,83 ft / 572,83 ft) x 71,59 ft x (20,60 / 21,62 ft)
(174,60 m / 174,60 m) x 21,82 m x (6,28 / 6,59 m)
- Torpedo Bulkhead - Strengthened structural bulkheads:
1,57" / 40 mm 374,02 ft / 114,00 m 18,37 ft / 5,60 m
Beam between torpedo bulkheads 71,59 ft / 21,82 m
As mentioned in the Parthian thread, your TDS has no depth.
With the 40mm plated just inside the hull plating, it will not be very effective.
If you want a minimal 2m of expansion space on each side,
then the beam inside bulkheads would be 21.82- (2x2) = 17.82.
That would make the needed belt length 129.88m
Which you should then change your Freeboard Tab's forecastle and stern lengths to get to.
At 15% and 10% it works.
But then your vessel is down to 0.88 comp hull.
As another issue,
I tried to model the vessel, and when I put in your Bow (17.5%) and stern (18.5%) the
Armor "Default" tab gave a length of 111.74 - not the 114 you have.
That Bow-Stern length is what it calculates the armor deck weight from.
So it was calculating the 45mm armor on less of the hull than
the belt would indicate.
Test 1: Forecastle 15%, stern 10%, deck armor 0 / 45mm / 0 = 834t Deck armor, default belt length :130.95.
Test 2 : Forecastle 5%, stern 5%, deck armor 0 / 45mm / 0 = 911t Deck armor, default belt length :157.14
Also, Snip's Ship Design Guidelines state "Torpedo defense systems (TDS). Use the "Additional Bulkhead" setting."
I do not completely remember the reason, it may be SS has a flaw with that setting.
I also noticed the bow is 2m higher than the forward part of the ship.
I've made the opinion before that the guns seem to sit ~1.5 m off the deck, so a flat shot would not be possible.
However, for almost all combat ranges, you would elevate slightly and so fire over your bow.
So this is not the concern it was when Fire Control ranges were 6000m.
Sorry to bring up these issues this late. :(
Yeah, strength bulkheads are reinforcement of the ships structure. So it inflates composite strength....but if the ship were to take a torpedo hit, it would cause full on structural issues. Strengthened bulkheads just aren't viable past about 1908 or so, they're more for small mines and underwater shell hits.

The nine-gunner can work against second-rate powers but it's going to have trouble with battlecruisers, perhaps.

I do not completely remember the reason, it may be SS has a flaw with that setting.
It is a flaw with SpringSharp in that adding to the Strengthened Structural Bulkheads option only shifts weight around from the Hull, fittings & equipment section to Armor -> TDS with no effect on composite strength. In some testing back when that became a part of the rules, someone was able to make a ship with something like -15% Hull, fittings & equipment which clocked in a 1.00 composite.
This person is my new hero.

Parthia does not really have battlecruisers. All we have is dreadnaughts.
The closest we have is the two 26knot 10x 365L45 ships.
Which I guess means Parthia is a 2nd rate power.
It is similar to Byzantine/Parthia's older Armored cruisers.
Naw, I'll count those two 26 knot ships as battlecruisers to keep you in Tier One.

It is not a surprise that a 12000t -27kts cruiser is less strong than a 18000t - 29kts cruiser.

Considering what it's guns are, I think that the decks are a bit 'thin'. I'd want at least 2in of deck in this era, given that there are plenty of ships running around already with guns that will be at or close to 2in of deck penetration at long combat ranges.

Posted in "Parthian Vessels 1916 onwards"
QuoteByzantium has a similar approach with the Colonial Cruisers (AGB4600). 3000t to 6000t and able of escorting BBs. From 2T2x152 , 2T2x191 to 2T2x254 all 27kts.
However, older 27kts cruisers are going to be affected to colonies.
27kts is a correct speed for Colonial Cruisers.
Jef forget TGB concept...
"Destroyers have over 50% of engine displacement, often 52, 53, or 54%.
TGBs only have 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 work, patrols, escorts.
2 - Close protection of large combat ships vs Destroyers and MTBs.
3 - Scouting & reinforcement of the combat fleet."
Last Byzantine TGB were 1000t & LD 1910.
1918 DD2000t techno could be interresting...LD in 1922.
1922 Engines techno give engines too light & speed too high to have 3x191 => the TGB must be over 2200t.
Out of rules...
Just 3x152 to have poor ship...

The thing I hate about 3 guns, especially when you start getting ranges that can really stretch out due to improved fire control, is that 3 guns gives you very few data points for adjusting fire, and cannot be fired in half-salvoes. With 4 guns, you can 'barely' fire half-salvoes for adjustment, though you'd need either luck or full salvoes to register hits. With 3 guns, even full salvoes have pretty low probability when you consider the '1 short, 1 long' straddles with the remainder being most likely to actually hit.
I'd opine that if you're running 3 guns like 191s, which will have a RoF roughly 1/3 slower than guns in the 120-140mm range, and you're not running a ship with substantial armor to withstand the hail of fire from those guns out at 12+KM, then you're in a situation where you may not have a ship that's combat effective by the time you get a solution with the big guns....despite the fact that the big guns can mission kill a DD or small cruiser with 1-2 hits.
Later on, when Radar and highly precise FC comes into play, smaller numbers of guns start to gain effectiveness because the FC systems allow for much better solutions and more hits with fewer adjustment rounds.
I agree with you.
This 1700t SS is made to see what is possible with TGB concept. It's not in my Building Plan.

I did stuff 2x8" guns in a 1500t destroyer... although I figure their main role will be raiding/harassment shore bombardment.

Yeah, I built a few E-class DDs with only 3 guns. They're built as commerce raiders for long open ocean voyages though, so within that they work.
Not to derail Jefgte's thread :)
Tac is right, 4 guns is more desirable, 3 is 'workable' but less desirable - just how that shell ladder looks.
There is a note in 'Ship Design' under fire control about this, but to expound further :
From what I've read, you want 2 short, 1 'straddle' and 1 over.
The straddle though can be hard to see, so those 2 shorts are really your guide.
The overs are harder to see, so you can 'live' with 2 short and 1 straddle , and shift that to 1 short 1 straddle 1 over.
Just having 2 guns means only 2 splashes, which the literature indicates is not sufficient.
This is ostensibly the reason for 10 guns - 2 x 5gun salvos, the 5th gun being the 'safety' for any loading issues,
to ensure you would have 4.
With the 8 guns ships, they basically decided that the loading issues were infrequent enough it wasn't mandatory.
ROF should have bearing on this too. You need to be able to put that many (3-4) shells out every 30s
in order to make a track. HMS Furious's 2x18" would just be too slow to even try to use the process.
While I think a Sverige with 4x 12"...but 3rpm, is a little slow, but could have a reasonable chance at making a plot.
Drop down a size class and ROF increases and a 4 gun battery becomes more acceptable.
Late in the period the optics got better, there was aerial spotting, and then there was radar, so this became less important.
