NUS Light Cruiser for 1913

[Sachmle]

I should have 1912 engine year by then, from the Tech trade w/ Italy. So at only 830t heavier than the Unions I get allot more firepower, to the tune of 438lbs of shell weight, almost 2x as much w/ the same speed. Whatcha think?

Greatgoshamighty!
That's a heckuva fleet cruiser, Sam.
Nice one!

[Sachmle]

Well I can't build turret farm BBs so I'll build turret farm CLs.  ;D

[Jefgte]

hmmm...

The design is certainly not realist for boilers & turbines disposition...

Better disposition is, for the boilers:
1 funnel behind the bridge (before n°3 turret)
An other funnel between n°4 & n°5 turret (between lifes boats)
Engines are between n°6 & n°7 turret.


Jef  ;)

[The Rock Doctor]

Agreed with Jef on the funnel/boiler bit, although I think those are torpedoes amidships rather than boats.

I'd probably ditch the 4" guns - not really necessary if you have this many 6".

[Sachmle]

Fair enough, I'm not that knowledgeable on engine and boiler layout, so how about this?

Not enough guns! (ahhh!!! I'm sounding like Korpen now!) the equivalent NS Cruisers where to pack 12! 6 inchers by now. They probably weren't built, but the rumors should be making the rounds by now...

That said, not a bad ship. Definately something I would build. Gotta love the torpedo armament.

[Jefgte]

Good cruiser design, well balanced &... powerfull TT armament

Hm,"future growth" = Mines :)
"85t Additonal damage control equipment" better spent on mine IMO...

Pretty nice ship overall, but need more mines. :)

[The Rock Doctor]

I'm thinking the torpedo armament is excessive, myself.

On the other hand, I like the pic better:  both from an internal arrangement perspective and from the aesthetic perspective.

[Sachmle]

I was thinking the same thing about the TTs, maybe go w/ 6 twins for 12 total, or 4 triples. And, Korpen, since you seems so dead set on mines on her, how many would that 85t's give me?

Less TTs, reintroduced some of the 4". Used 100t of the misc weight for minelaying equipment and mines. Not sure off the top of my head how many mines that'll be, but strictly offensive mines.

TT armament exessive...Yes, they are in the places of the life boats :D

Seriously, in these places , TT could rotate to 30 or 45° max. That is short...



Jef  ;)

[Sachmle]

Where would you recommend putting the TTs? The lifeboats are stored next to the fore funnel below the searchlight platform.

[Jefgte]

With a slim superstructure under the 2nd funnel, TT could take the place on the sides.

hmmm....
17.07m beam...total rotate is perhaps possible.

------------------------------------

You can also drawing a cavity in the superstrusture under the fore & aft bridge for a total rotate
