again, I'm not super experineced by I'll try...

Maybe its just me, but IMO a ship of 25k tons should have around 20k broadside weight. I doubt you need so much deck armour, as
Quoteplunging fire doesn't have alot in this time period
I would probably give it 12 12" guns (4 turrets) as other battleships have 14"-13.5" guns. When will you need 12000nm at 15 kts, it would help if I knew what the range ast max speed was. But all in all its a ok design (to me)

Why lug the belt then?  Why not a fully armored armored hull?
With that deck you're protected against any plunging fire.
And with that speed you can dictate range to any ship with guns large enough to hurt.

Post by: P3D on August 29, 2008, 10:24:06 PM
AoN requires the relevant technology available to research from 1912.
The belt is shallow and most probably will not protect either the waterline or just expose the vitals.
Any hits on the totally unprotected ends would take over any speed advantage. I'd hit this ship with large-caliber nose-fused HE to destroy buoyancy reserve.
You will not need thicker than 4" armor until mid-1930s. The lack of TDS might not be a good idea long-term - 27kts might be enough not to be threatened by destroyers, but if you use the hindsight for WWII-level deck armor you should not discount torpedo bombers either.

I was waiting for you to chime in P3D, Everyone missed the "problem" (or atleast by my interpitation of the rules its a problem)  its USS Alaska I went through all the stock ships in SS (woot for a new install where i havnt boogerd em all up).  The WW2 Vintage BBs & BCs all use mount and hoist on their secondaries.  I didnt even trim Alaska up much (like fixing the horible armor layout / the over heavy deck for our period).  the point was I was wondering if mount and hoist secondaries were ok (I even simed Iowa and it wouldnt work with turreted secondaries but was perfect with mount and hoist).

edit
I should have pointed this out before what I am realy wondering is this.  Is this just a bug in SS or were what I always thought were turreted secondaries realy just mount and hoist?

I am just going to say: She got a transome.

LOL i didnt even notice that.  as I stated above my question was about the secondary guns, (aka were the alaskas and the iowas realy equiped with mount and hoist for their twin 5" mounts or is this a bug in SS)

It looks as if the twin 5" L38 turrets were what we call mount and hoist.

A ring welded/rivetted to the deck(with re-enforcements), a box of good steel over the gun mounts, a hole in the deck and a hoist dipping down trough a steel tube to get the munition up from the magazines.

Thanks M now off to come up with a real BC ^.^ (what my DD is finished and if I might have to fight people that build BCs I better have my own)

Just remember that twin mouts have to developed before one can start mounting twins.

As for the ships itself, either increase belt height or lower the amount of fuel, she carries so much fuel that it will be about 1m difference between full and normal load. This leave only around 1m of protection above water when fully loaded, with wave motion it could mean that damage above the belt can cause flooding, further submerging the belt...

Post by: Tanthalas on August 30, 2008, 12:49:47 AM
I think DF may already have developed a twin 4" or 6" got to look again, that was just a half assed example of what I was thinking about (I would also likley mount more and larger guns on it to say 13.5s or something like that)
Title: Re: A very Serious Question.
Post by: P3D on August 30, 2008, 01:07:17 AM
NS should have finished the relevant cruiser tech by 1909 or so, I guess they have twin 6" hoists too.
The US 5" was mount and hoist, the UK 5.25" was full turret.
For the same caliver the Nverse difference should be regarding that what armor you put on it.
But if you want full 6" turret then by the newest rules don't need to have new techs just develop the turret. They are kosher.
Title: Re: A very Serious Question.
Post by: Tanthalas on August 30, 2008, 01:11:11 AM
im still operating under the old rules i think, mount and hoist can only have 1" armor right? also is it just me or is 6" a tad heavy for a QF gun.

Actually, if one goes strictly by what the rules in the rules section say, the BB tech do neither allow or disallow turreted secondaries. At the same time the cruiser tech says:
QuoteBattleship Architecture is not valid for guns 6.5" and smaller. To have armored turrets with small guns, this technology is required.
So going by what is written, I have a hard time seeing turreted secondaries as being in accordance with the rules.

I'd like to know from the original mod group:

-Why did the 1910 CL tech allow twin-mounted batteries?

-Why did the 1912 BB tech allow it?

-How was the difference in dates accounted for?

Continuity.
#1 was the next cruiser tech in N2verse, and Desertfox was already researching it.

The 1911 BB tech was merged from three technologies - Main turret arrangement, secondary arrangement, number of guns per turret. And the cruiser tech already allowed hoisted secondaries - no reason not to allow them on BBs. As it contained significantly more stuff (add AoN), it was to be twice-long tech.

As Rocky specifically mentioned that he sees  no need to develop technology for turreted secondaries, there's no one. I argued that when the tech was separated into two the quad turret tech offered obviously less advantages than the BB protection tech or any of the previous BB techs (or any other techs, TBH), but no.

According to your reasoning rules neither allows putting twin hoists on battleships or destroyers either.

No, according to my interpetation BB and DD tech do not say a word about that in either direction, but there is a "cruiser" tech that DO regulate the use of guns smaller then 6,5´. So if one want to use guns smaller then 6,5´ one will use the LC tech, no matter if one is using them on a cruiser, DD or BB.
Title: Re: A very Serious Question.
Post by: Tanthalas on August 30, 2008, 01:19:42 PM
this tech?

Light Cruiser Architecture
1910 Cutting Edge (+5): twin gun mounts

Already have it ^.^ (well the NS already have it and im operating on the assumption im going to get them) not to mention they already have a twin 6" mount (its actualy on some active comands already)

So the omission of mentioning smaller than 6.5" guns for BBs means that you cannot build full 'turret on barbette' secondaries (even if a mod expressed intention not to make a separate rule for it), but the similar omission of mentioning hoisted mounts in the DD/BB tech would let you use the cruiser tech too build such?

Missunderstand Me correctly.
I simple meant that as I read things as they stand, on what kind of ships the guns are mounted is irrelevant. If one wants to develop guns smaller then 17cm in a turret with barbarette, one will need the 1920 LC tech, if one wants to develop twin gun mounts one will need the 1910 LC tech. This irrelevant of if you if you then choose to build a BB, LC or DD carrying the gunmount.

At least that is how I read things as they are writen in the rules.

well I didnt know and thats why I asked lol, but I think I understand that its ok for me to build twin gun mount and hoist secondaries (like the alaska used) and realy that was my Primary concern ^.^

As far as i can tell, it is perfetly fine (if you got the mounts developed for the guns in questrion) :)

The intention of those rules as I wrote it was to limit their validity to ships built under  'light cruiser' rule. Now it is up to the new mods to interpret it.

NS does have a twin 6" gun mount in service. It is a mount & hoist similar to the OTL Omahas, and is limited to 1" armor. If it is allowed, I would use it for any new battleships/cruisers, while sticking to single 4" guns. Don't bother developing twin 5" mounts. The need for those is still 30 years into the future.
