Triunfante revisited...

[The Rock Doctor]

Since nobody's posted anything today, I may as well let the cats out of the bag.

The revised Triunfante class battleships will be laid down in 1909.  A few changes have been made to the design:

-The hull sits a bit lower in the water, so will cost me a bit more.

-The forward turret arrangement has been changed to A-Bs; though the design does not make it clear, it will be a new gun design, too.  Sighting hoods have been removed from the turrets, allowing fire over other turrets.

-Consequently, additional 14 cm guns have been added to the secondary battery, at the expense of tertiary and QF battery guns

-More compact, higher superstructure forward

-Improved armor protection (the belt length reflects what the picture tells me I need, not what the SS report says)

-Slightly faster, with oil-sprayed coal-firing boilers; though the range has gone down, it's acceptable for GC standards.

U.S.S. Wyoming eh... great now i have to come up with somthing new.

[Carthaginian]

Very scary... she lacks that certain 'strangeness' that made the original so cool, but is a pretty capable and pretty looking ship. Very handy and very powerful. The pair will make GC very respected in the world of turret farms.

[Tanthalas]

GC just needs to bribe me and get my trip turrets, then they could have 12 guns with 4 turrets. 

[Borys]

Ahoj!
Are you sure you can't find space for turret no. 7?

Borys

[Ithekro]

Baby steps.  ;D

[Borys]

Ahoj!
Are all the turbines between the boiler rooms and P and Q turrets, or is half of the turbines between Q and X?

The ship looks as if it lacked space for turbines.

Maybe eliminate stack 3,  to show space for the turbines. And/or maybe also space out Q and X a bit.

I have no idea where the turbines would be; having based the design on USS Wyoming/Arkansas, with similar-ish dimensions, machinery and armament, I'd assume something similar to them.  I don't know what that does for funnel arrangements.

GC just needs to bribe me and get my trip turrets, then they could have 12 guns with 4 turrets.

Appreciate the opportunity to slip Italy bribes, but GC can develop them itself.  It was a conscious decision not to do so in this case.  I don't like the look, and will take the redundancy/rate of fire advantage of six twins over the weight-savings of four triples.

U.S.S. Wyoming eh... great now i have to come up with somthing new.

Unless you think GC and Italy have reasons to butt heads, I don't think that's really true.  Well, okay, maybe the Italian leadership will want to engage in the proverbial pissing contest.

Regretably true.  Oh well.  The look's still relatively unique for this world.

Nah Italy just likes wierd ships, and since someone is already building Wyoming ill have to come up with somthing else wierd to build. =P

Gypsy crone looking into crystal ball
... I see an eight turret ship in your future ...

Ah yes...:

;D

This ship is not a turret farm, a N-Verse T Farm must have at least 8 twin turrets to qualify, a semi-T Farm must have either 6 twins or  8 with half being twins. So far no ship yet qualifies for true T-Farm status, but Satsuma and GN both qualify as semi-Turret Farms.

@ Rocky, the first ship definately had that intimidation factor going for it. Imagine the look on the Admiral who manages to cross the GC Fleet's T! Now if the original ship had had two superstructures, now that would have been scary!

@ Thanthalas. Want weird? How about an Andrea Doria with quads and triples instead of triples and twins? That would be...say 18 guns in 5 turrets!

18 guns drools

[Ithekro]

Hmmm.  So will the first true "turret farm" ship be the designation for all of the type that come after her?



This is a little advanced (not much though) and also only armed with 8" guns, but would this qualify?

[Carthaginian]

LOL

Look everybody, a fireworks stand!

[P3D]

Looks like the Navalism dutch AFs. Wing turret magazines to protect machinery spaces.
