Cruiser Ideas

[Sachmle]

If NAaB is in the right ballpark the armor should be proof against a 260lbs 8" shell from 7,200yds (belt) out to 18,000yrds (deck) and against it's own guns from 11,000yds (belt) out to 18,000yds (deck). Also, Swampy was kind enough to do a story about how the tripple 24cm/L50 was the same barbette as the twin 28cm/L45, so I could swap them out rather easy if I so desired.

More of the super cruisers, if you can fit 4x2 11" I would got for that myself.  Otherwise a nice cruiser killer.

[ctwaterman]

Hmmmm it appears to be right in the the 17K ton range where the Nassau treaty group looked over a 12 x 9.2" gunned cruiser killer.  A nice ship I like them but Italy probably cant afford more then 1 or 2 of them.

Does it worth building a cruiser killer with specifications to face the old Swiss cruisers with 8" guns?

[Sachmle]

Does it worth building a cruiser killer with specifications to face the old Swiss cruisers with 8" guns?

Really wasn't thinking about them, but still a good point. I looked over the "Cruisers of Navalism" and for ships in this size bracket (16-18,000t) 11" is the average main battery size. Belt is proof against 11" from ~12,000yds out and deck is proof from ~19,000yds in.

I'd have more than four secondaries on a side, and increase draught a bit. Also, ~2.4m deep decks suggest 1.2m armor belt above water, and 2.15m below - the latter is excessive.
And on a 18000t ship, I'd put a TDS.

Building 18k ton ships to kill 6k ton ones is not very cost effective.

[P3D]

Building 18k ton ships to kill 6k ton ones is not very cost effective.

As the ship seems to be able to take on three without risking itself much, I'd say it is cost-effective.

[Walter]

And on a 18000t ship, I'd put a TDS.

Despite its size, the beam's so-so for an effective TDS.

[Kaiser Kirk]

It's interesting as it's similar- but overall better - to my Donar.  My engine tech isn't there, and I use coal, plus I made some purposely different decisions for a slightly different role.

For my part, I found a TDS unworkable unless I expanded the ship to over 20k light, and you'd probably want another meter or two of beam to fit minimal internal bulges and still have room for twin 11". Figure 17-18m minimal beam for twin 11", and 4m for each internal bulge, 25-26m would about minimum.

[Kaiser Kirk]

Block coefficient: 0.491

Based on the BC's that Guinness has posted, I don't think that BC is enough. The only large warship with less was the CV Ranger, but even 6" cruisers are over .5

http://www.navalism.org/index.php?topic=727.msg44539#msg44539

Also, why trim the ship up to 57? It doesn't seem to have any benefit.

[Sachmle]

Block coefficient is a byproduct of 1) Not wanting to go over 18,000t 2) Following P3Ds advice to deepen the draft.

Trim to 57 increases the steadiness. While not 70, 62 is better than 58.
