[Jefgte]

I have not finalized my PLAN for 1924
There will however be:
2 x BB x 34000t
4 x SC x 6000t (?)
8 (?) DD x 1500t
4 (?) TGB x 860t
6 (?) TB x 500t (Mayun Class)
4 SS x 750t

[Jefgte]

I prefer this SC.
Update SC7 with 140/50 guns (was 120/45).
Certainly better vs DDs or TBs.
Increase the speed by 0.9kts is not enough interesting.

[The Rock Doctor]

Will the mix of 191 and 140mm guns confuse fire control, or is the notion that the 140s are plunking at a different target?

[Jefgte]

7135nm(13214km) - 14kts

[Jefgte]

Like the Parthians, with colonies scattered over all the oceans, Byzantium needed many Cruisers and Destroyers.
PLAN in the years 24 - 25:
8 x Scout Cruisers of 6000t.
16 x 1500t Destroyers
12 x 860t TGB Colonial Patrollers (sort of colonial destroyers).
18 x 500t torpedo boats.
All in all, many ships powerful enough for a reasonable tonnage.
No super cruisers or super destroyers.

Total for 1926
36 SC (30 with 191mm guns)
82 DD (750t mini)
48 TGB (500t to 860t)
92 TB (400t to 600t)

[Kaiser Kirk]

I prefer this SC.
Update SC7 with 140/50 guns (was 120/45).
Certainly better vs DDs or TBs.
Increase the speed by 0.9kts is not enough interesting.

Similar in several ways to the Mouleck IIC I'm considering.

I lack the QF weapons, as I think the single 180 (or 191) should pivot fast enough to engage torpedo craft.
Your guns are heavier do not seem to have any additional power assist tonnage, so perhaps the secondary
is more useful.

I am once again eyeing "Torpedo Boats" I have a 650t design that looks appealing for some locations.

One thing though :

7 x Single mounts on centreline ends, majority forward
      2 raised mounts - superfiring

How does that layout work ?

There are several potential ones, but what come to mind
is the en echelon arrangement of some German cruisers for their forward guns.

I lack the QF weapons, as I think the single 180 (or 191) should pivot fast enough to engage torpedo craft.
Your guns are heavier do not seem to have any additional power assist tonnage, so perhaps the secondary
is more useful.

I still hesitate, 120 (22kg) or 140 (37kg), I haven't made a final choice.
On the same target, 191 +140 practices alternate shooting.
140s are more effective vs DDs & TBs. They can also have some effectiveness on cruisers.

How does that layout work ?

I think 7x191 doesn't change much compared to 6x191.
Doubling the firepower for secondary artillery (120 or 140) is more useful.

This is helpful when there are non- standard  weapons layouts.


While I get the concept of 'alternate shooting', I think it may have problems in practice.
Even if there is the main battery volley followed 5 seconds later by the secondary,
the two shells would have different times of flight, meaning the splashes will not be neatly separated.
At shorter ranges, where the 14cm would be more effective, trying to limit volleys to between the main gun salvos
would also restrict ROF to the main gun's.

Parthia has the concept that for some ranges, the secondary with HE can be used
to create the spotting ladder, while firing for effect with the main battery.

In practice, for Mixed battery ships or  calibers not widely separated from ,
I treat them as 'multiple ships at one target' which matters little at short range,
but really hurts at long ...but the 14cm splashes will not be distinct at long range.

Like the Parthians, with colonies scattered over all the oceans, Byzantium needed many Cruisers and Destroyers.
PLAN in the years 24 - 25:
8 x Scout Cruisers of 6000t.
16 x 1500t Destroyers
12 x 860t TGB Colonial Patrollers (sort of colonial destroyers).
18 x 500t torpedo boats.
All in all, many ships powerful enough for a reasonable tonnage.
No super cruisers or super destroyers.

Total for 1926
36 SC (30 with 191mm guns)
82 DD (750t mini)
48 TGB (500t to 860t)
92 TB (400t to 600t)

8 x Scout Cruisers of 6000t.
=>
4 x C8 - 4780t (27kts Colonial Cruiser)
2 x C9 - 5520t (29kts Fleet Cruiser)

Torpedoes on a monitor is unconventional, although the ship seems more like an escort cruiser than a conventional monitor as I think of them.
