Now that's interesting...

[Tanthalas]

lol i have bene playing with it for 2 weeks, finaly came up with somthing half way decent.  Serious opinions, would it be worth building?

[The Rock Doctor]

If you're willing to accept the vulnerability of the main battery (being in just two turrets) then yes, it may be worth building.

im still thinking about that part... im not against twin turret ships, although i am playing with a 3 twin varient, just not sure i like it as much ya know.  i kind of like the long and lean look i would have like this.

[Carthaginian]

She's definately well armed and fast as a theif.
I'd say 'go for it.'

[Desertfox]

Nice! Me want! ;D

Seriously, NS will buy modified export versions of her if Italy is willing to sell.

[P3D]

A bit more range would help.

[Tanthalas]

A bit more range would help.

6000@10 kts is my entire fleet (and yes i set it at that then modified the cruise range till it matched @14)

Export version may become available

that was the plan I took the max trubine HP as my starting point lol

I have some real doubts about fitting triple 20cm guns on a hull only 15m wide.
It is a bout the same with as the German K-class from the late twenties, and the triple 15cm was a tight fit on that class.

its tight, but i think it would fit, I actualy have alt navals ship drawing thing, let me do a quick look of her

[Tanthalas]

ya i think they would fit ok opinions?

[P3D]

You have 20-22' barbette ID and 0.52 B.C. And a huge machinery pushing the turrets to the ends. SS2 allows it, but it might not be possible in real life. 48000SHP is a bit too much for 1909 machinery. OTOH, two triples fit better than four twins.

Increase ammo from 100, too.

[The Rock Doctor]

That's a good point about barbette diameter versus hull size; I think the BC is quite reasonable for a cruiser - even high, perhaps - but the beam is on the low side...

[Tanthalas]

Ok I was going to mail you P3 but when I tried I couldn't get back on the site for a half hour lol...

Horse Power, its 12000 per shaft right?

Ammo I know its short that is the ships planed flaw.

Would the guns fit? Not sure I, I think the only real reason no one built something like this otl was that there was no reason to otl.  That said my purpose for it is obviously scouting, and acting as a forward fleet screen.  Basically what the USN currently uses their Cruisers for.

Not trying to be argumentative or rules lawyer im seriously asking here, and defending my design as best I know how.  I openly admit I like to push the limits and that was the point of this ship it pushes my tech to the limit.
