USN ships

[KWorld]

Which I knew *starts lobying campain for a USS Cheyene* on a slightly diferent note, and I thought I was getting out there with 13.5K light ACs... Also you might want to consider somthing diferent for the layout, I went ABY because I was convinced (ok ok so snip yelled at me enough that I reluctantly agreed) that AQY proly wouldnt fit with the necessary Huge as Engines.

KWorld, I find your choice of name erm, "intriguing".

It's named for the capital of the state of North Dakota.  :)

If you look closely, none of the USN 3-turret designs are AQY (though the BBs could probably manage it), they're all AXY with the aft turrets back to back (a la USS Delaware.

[Tanthalas]

AHHH that would work (I hadnt realy looked) my own AQY is more like Derflinger (or atleast thats how I envision the layout)

??  Derfflinger was an ABsXsY........

[Tanthalas]

aBQy true story (actualy it wasnt a true Q or X as one engine room was aft and one foreward of the turret in question)...  The Iron Dog is one of my favorite ships of all time (I even have a fully acurate Spring Sharp of her)

Fairly sure the maximum allowed TB is 1.5" man... other than that looks good.

Yeesh, shouldn't be there at all.....  And just a reminder, Strengthened Bulkheads don't work correctly in SS3b3, we need to always use Additional Bulkheads instead.

I use Strengthend till I have actual TBs anyway, mostly just cause I get sick of changing the distance while im working on a ship.  on another note, I havnt messed with BCs much at all (or dreadnaughts for that matter) I know where I will be in like 1907 but not exactly how I will bridge from Predreads to Dreads.

[Jefgte]

I note the oL: 184m & the high speed: 25kts...

1907... wait & see

;)

The problem with Strengthened Bulkheads is that they just move tonnage around, rather than adding any additional weight: the weight added by the bulkheads is just subtracted from the hull weight, you're not actually adding any weight.  They're, effectively, free.

[Tanthalas]

Oh I know I was one of the first (here anyway) to realise that.  once im puting actual bulkheads in (aka adding a Torpedo bulkhead which im a huge beliver in btw) I switch (like on the ship im about to post which when I make her rules compliant I dont like nearly as much)

hold on im making sure my "new" RMS Nike is fully rules compliant before I post her (annoying things rules always interfearing with what I realy want to build and messing up my perfectly good storyline ideas)
