hmmm. looks like something the Armada would nickname "cacafuego"

I think at the least you'd want deck mounts with hoists to ensure a steady ammunition supply.

All these powerful little cruiser designs may simply indicate that we were too generous in allowing hull strength to dip down to 0.75 for ships under 6,000 t standard. I'd be curious to see how an accurately simmed out Dido, Arethusa, or Atlanta came out.

Foxy - whether or not the design itself is good, does Australia have the resources to invest in this fairly specialized design, and is 1933 the time to do it? I'm in similar shoes and can't help but think that a solid multi-purpose cruiser is a better fit for my overall needs.

:-) no wonder it fited in 5,000 tons. Next version will be bigger.

Actually my thinking would be the reverse of yours. I feel that one specialized ship is better than 2 multi purpose ships. So it does fit in my plans.

The trick with specialization is for the specialized unit to be where you need it, and not where you don't.

Personally I think you need more shells for the main guns if you plan to have this thing try and shoot down waves and waves of aircraft (or just one Manzo).

I was thinking more like 250 - 300 shells per gun.

Latest version, considerably bigger.

I have decided not to build the larger versions. No country would spend so much on a weapon against a non existant threat. Instead I will probably build this one. It is essentialy an overgrown destroyer. And as such it can also serve in the DL role.

I wouldn't even bother with the 0.50" deck armor, better to stick it on the CT. Also a little nitpick on the aftermost 40mm mount on the stern. It will be incredibly wet, better to place it along side the foremost mount between the torpedo tubes.

No country would spend so much on a weapon against a non existant threat.

The threat is real and it lives somewhere North of Australia.
I prefer the Italian Ruggiero... but that is just me.

Quite a nice ship, and with cruiser hull strength as well.

Great picture, I hope we'll see some more in a similar style.

What sort of 4.7" guns are you using? 4.7"/40 QF Mk VIII like with Nelson/Invincible here?

Will fix. The after 40mm mount will be split an placed either side of bridge like in my destroyers.

Well the accident happened in bad weather so Australia doesnt think it is too much of a problem.

Yes

Nice side view. Her funnels are probably a little bit short.

Will you also provide a top view?

Here you go. Together with a slightly improved version.
