so what do you all think  mbe some biger guns at a and y positions?

The low stability might be an issue - most of us have taken to keeping that score to a minimum of 1.10 - and I am, myself, not a fan of the heavy torpedo armament carried out in the open... even besides the fact that my personal case of 20/20 involves ships vs. aircraft for scouting.

That said, among those presented, I'd probably go for Plan B.

The high level of protection - incl long (141% vs 'normal')and deep* main and upper belts + lots of armament - 10/12 main batt. + 12 TTs - is probably making them rather top heavy and reflected in poor handling - Stability, Steadiness (very important for gunnery perfmce in smaller ships) as well as Sbt Qlty

* in particular - total height of both belts together is 24.6'  vs 16' freeboard - 8' of main belt is underwater!! - you can safely reduce depth of main belt - to 11/12'?

Also - deck space - looks like will be very cramped - 5/6 centreline twin turrets and 4x3 TTs - have you checked deck layout to see if it all fits on the rather short 400' hull?

I think practical operation of such a ship would lead to some redn in armt/main belt


Valles

Deep belts are a good idea, despite their weight costs, for several reasons. First, particularly on faster ships like this one, is the fact that bow waves don't merely rise above the nominal waterline - they drop just as far below it afterwards, which would leave unarmored hull exposed to shellfire on a shallow belt. Second, damaged ships list, raising the waterline on one side and lowering it on the other; again, a deeper belt decreases the chance that that list will go far enough to expose a vulnerable point. Third, one of Springsharp 2's sins, in my eyes, is the fact that it provides no indication whatsoever as to the degree that a ship's draft varies depending on its loading; I've seen designs that would have their belts almost submerged when fully loaded and actually out of the water when running with tanks dry.

Armament outfit looks practical

Armour deck definitely useful - perhaps 40mm is a minimum vs 5-6" gunfire - but doesn't save much

Stability now gives more reserve in case of damage

But the design still focuses very much on protection (Armour at 28% is pretty high for Cruiser) - probably at the expense of steadiness and seakeeping

  Really depends in what situation/conditions they will likely operate - at the moment I think they would suffer in moderate-heavy seas

I think may help on same tonnage:

   - raise focsle

   - reduce draft and increase beam - then tweak trim to increase steadiness


Also - could reduce average main belt thickness to sim some reduction of lower edge of belt - lowest 4' is least exposed

  ?? - still some scope to reduce length of main + upper belts - replace main with thinner end belt to help protect flotation

Twin gun mounts have to be researched separately, taking two half-years to complete. As Firanji completed digesting the light cruiser tech in 2/1915, it is not possible to have the gun mount ready to be used on a design until 1/1917 at the earliest.

   - Armour deck: 1.97" / 50 mm, Conning tower: 2.95" / 75 mm
I do think she is somewhat over-armoured. Given the belt armour there is less need for a very think deck, so I think it could be cut to around 30mm without any real loss.
I also think that the amount of belt armour is excessive as well. Would recommend cutting it about 1m in height, and reduce thickness somewhat (to about 9cm), perhaps increasing the height of the upper belt 50cm to compensate.

At only 27 knots she would be the slowest "modern" Firanji cruiser, think you should go for 28kts minimum to allow her to function with the existing ships. Her range is a bit low for 1916 engines and 100% oil, in fact she carries much less fuel then the preceding classes counted in tons.

The weight savings should go towards first increasing speed to 28kts, and then to make the ship smaller, as the offer very little increase in combat capability for a huge increas in cost compared to the other Firanji cruisers.

A problem with the cruiser is that you have chosen to restrict her to a type 1 dock, and I think a 5000 ton cruiser is really to large to be squeezed into such a format. If wanting a ship for type 1 docks, go for something at most 3500 ton.

  Yes - seem good little ships, handy for most CL work - why not build a few while you work on the later tech :) - small cruisers are always kept busy

Some small points:

-  would benefit from more shells per gun main battery - maybe 180 ish

- given single mounts, might be possible to fit in 5 centreline and just 2 wing turrets - but the saving is probably minimal

well any thing to say bsed on the Saladin class ish kind of maybe

I think Gar Marr is going to have deck space issues.  There's a lot of weapon mounts there.

On the other hand, the torpedo bulkhead is of little value for a ship of that size, so lose it and you can probably bump the speed up.

I don't know: knowing how big the Confederate twin 5.5" gunhouse is (12.5 feet from the axis of rotation to the back of the mount, 18.5 feet to the end of the barrels, so you can use those two figures to give you approximate training arcs, etc.) The CSA single deck mount needs slightly less space, of course.

So given a hull 557 feet long and 55.7 feet in beam, I think all those gunhouses would fit. It wold be tight though, and finding space for necessary command and control, ships boats, etc. would be difficult. The forecastle might have to be shortened down to 15% of total length (or even less though). Also, a better arrangement, given the step in the hull might be a pair of twin mounts with one superfiring aft, a single twin mount forward before the bridge on the forecastle, and 3 twins along either side, giving the same number of guns, but eliminating the singles. This would save some length for other stuff, like the 75mms.

The thing that might not fit is all the torpedoes though. I'm not sure how I'd arrange them, but I think at least some of them would end up on the quarterdeck.

I agree with Maddox on the TDS. There's not enough beam for it to fit adequately really (despite the fact that SS let's you do it). 28 knots is probably not fast enough for a (heavy) light cruiser with 1916 engines in my opinion.

Necessary disclaimer: In speculating about deck space, I'm just drawing this ship in my head, so actual results would vary.

8000t with 20x140...

This cruiser is made to repulse DDs divisions...

And I tought the Demarce IIIb Volcano was a badass cruiser with 12 140mm guns in twins.
