Looks like Gravina's version is better armed, armoured, longer ranged, and comes in at a slightly lower displacement than Hrolf's....unless I'm missing something. o.O Gotta say I'm preferring that design, though it means I'll be having to redraw it.

btw, Gravina I hope you don't mind me using your ship graphics as source material, I've been trying to keep a consistent look for the fleet.

Thanks for the welcome Earl, and about my drawings no problem ShinRa, use them if you´ve to.

Oh, and I´m not sure If you´re aiming to a single gun type for all your CLs, but you can change the 16 5.5 to 12 6 inchers without any change to the springsharp report, just noticed it while changing some parameters. Just in case you want a heavier shell.

Opinion seems to have it that the 5.5" has higher rate of fire, and is easier on the gun crews, with the only real drawback compared to the 6" is hitting power, which isn't substantial, and again countered by the greater number of barrels. Developing a more modern gun with a longer barrel based on the older 5.5" gun should help matters more, wouldn't it? (springsharp doesn't seem to differentiate on that note, though, and I'm unsure of any rules I need to follow for developing new guns)

I'm planning on using the 5.5" as secondaries for larger ships, and I'm not planning to regun the Dianas, so maintaining the 5.5" for the new CLs allows for better logistics (as they'd be the only ships with 6" guns), while the CLs get to scare people with quad turrets.

btw, is there anyway to shave off 3 ft from that design, Gravina? Unless someone knows a way to fit a 560 ft ship onto a 557 ft class 2 slip....

If not, no big, I'll just need the bigger slips I was planning on anyway

also, what scale were your hector and diana class graphics at? If my calculations are right, I got 1.82 something pixels per foot

before I work any more on this one, I want to make sure I haven't messed up somewhere, because it's looking kinda freaky;


that's with a 15% quarterdeck, and a 33% fo'c'sle, as I read gravina's springsharp, compared to the top view of the last version I did of hrolf's 8k design.

if this is right, i'm thinking of making it a v-hull so it'll lean back and go on plane at high speeds like a cigarette boat. o.O

One word : "Funnels"

I know, that's not what's looking freaky. The extremely long fo'c'sle is what's bothering me. Before I start cramming funnels and the rest of the details, I want to make sure I didn't misread something.

You probably want to move A and B turret forward by 50-100ft. I never draw exactly from the SS report. You need some artistic licence.

Those are two words, sir! And I said it wasn't finished, I didn't want to put on the secondaries, funnels, or other detail work while it still lookes like an offshore race boat. o.O

ShinRa - as RA notes, the drawings needen't slavishly follow the "fo'c'stle" and "quarterdeck" % in 'Sharp - do it so it "looks right". ;-)



...goes off to design 16 x 115mm light cruiser...

I know, I've been working on the drawing since then. It should be up in a little bit

And here it is;

Looks Canadian to me.

Good god this cruiser sure morphed! I like her allthough I'd lengthen her quarter deck, shorten her bow and make sure that belt covers all the 5.5" barbettes, then (too me at least) she'd look stunning.

Belt fixed on above pic. I kept the long fo'c'sle and short quarterdeck to reflect the SS report Gravina put out, but here's a version with more or less everything shunted forward for a more balanced look;



It probably wouldn't have gone through so many changes if I was capable of working SS. That being said, many thanks to Hrolf, Gravina, and RA for their SS reports, and suggestions.

I'd say shes done like dinner. Looks awesome.

That many guns @ 10-12 rounds/minute will be a sight to see, and utter hell to receive.

I'll be curious to see what quad-using country Canada approaches for design assistance on this one.

Definitely not a ship a destroyer wants to see in gun range, certainly, and any ship with a lot of exposed unarmored hull is in serious danger of being holed repeatedly.

Everybody hase 16gun ships I want one.
Is basicly an BB escort.
A progected escort for a rogected ship.

Or go for a quadruple turret, as drawn by Crystaleye;

OTL, the RN was the pioneers for the quad turret. Are there any real technical issues unique to a quad turret design that make it significantly more difficult than a twin or triple turret?


I like the longer f'c'sle myself, but the more balanced look is more realistic, and it gives more expansion room on the quarterdeck if needed at a later date
