Title: NUS Light Cruiser for 1913
Post by: Sachmle on May 04, 2008, 06:20:10 PM
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?

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.

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".

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.

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

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

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.

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...

Title: Re: NUS Light Cruiser for 1913
Post by: Sachmle on May 06, 2008, 05:25:41 PM
Where would you recommend putting the TTs? The lifeboats are stored next to the fore funnel below the searchlight platform.
Title: Re: NUS Light Cruiser for 1913
Post by: Jefgte on May 06, 2008, 05:46:34 PM
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

Figure a mine per tonne of miscellaneous weight set aside for the purpose.


I'd suggest just going with one triple bank on each side, at the second funnel - this is primarily a gun cruiser, it seems, and too many torpedo banks are going to interfere with firing arcs.

Alternately, I suppose, you could raise #4 mount and place it on an extended platform forward of the second funnel - then put a bank of fish under that platform.

Here's another pic w/ and overhead view. I moved the lifeboats to deck level and IF the TTs rotate on the aft axis they'll clear.

Not to be picky, but is there a crane to get those boats over the side?
Title: Re: NUS Light Cruiser for 1913
Post by: Sachmle on May 06, 2008, 08:40:55 PM
Rope, sweat, and the fact that if they don't get them over they're probably dead will cause the crew to propel the lifeboats into the water.  ;D


Fine. Picture a small crane on each side of the 2nd funnel, angled towards the boats.
Better yet, here's an updated pic and an SS w/ weight for the cranes.

There was this layout, SS report may come later. It worked, but I didn't like the looks so I deleted it. But anyway, I think it looks to modern.

You don't need misc weight for boat cranes.

That last one looks cool! If you don't mind I might have to borrow the drawing for when I get around to building New Zion's first cruiser.

The last drawing is good.

You could add some lifeboats on the deck under gun 5 & 6.
The cranes are too short to put the lifeboats in the sea.

I do not really think she look too modern. But if you made the funnels higher and thinner she would look older. But she put me in mind of some of the german light cruisers from the end of ww1.

I very much agree with Desertfox, cranes for boats do not require misc weight!
Nor for that matter do I think any normal fitting such as climatization, quarters for crews and command, signal flags, boats, derricks, davits, cranes, machine shops, toilets, provisions and extra paint need to have misc weight dedicated to it as I see some people are doing.

I'll provide for such fittings if I feel it's in excess of the normal amount for a ship of that size.  For standard loads, I assume it's just part of the "hull, fittings, and equipment".

I agree with you for the material inckued in
"Hull fittings, and equipements"

Meanwhile, some ingeniors in modern naval concept think that Springsharp is a very good approach for calculate warships at.... 95%.

IMHO, add 5% of light displacement in miscellaneous weights is good for the real feasibility of a warship.

As of right now this is the version that will get built. I realized that at 425' she would tie up my only type 2 dock, so I cut some 6", made the TTs centerline mounted, and chopped off some of the misc weight. Same hull dimensions as the Union class before her, but 3 more 6" guns, each w/ 100 rounds more per gun, and 2 more TT w/ the same speed and 250nm more range.

For comparison sake, one can see that the Toreador is more of a evolution of the Union as opposed to a whole new design.
