A class of 4 laid down in 1925. After experimenting with the Pisa-Class ships, Italian designers have returned to something more typical. A new 6"/50 twin turret is used with 4 mounts, giving considerable firepower for a 6,000t ship. The Armourscheme is the same as for Pisa, but with a 10mm thick splinter plate added to the deck armour. The semi automatic 65mm gun is used again; the RoF of 20rpm is found to be more than adequate against surface targets. The main advantage of the class is their 34knt speed which will allow them to run away if need be.

Because they are smaller than 6000t light, i've built them to 0.75 hull-strength. These are only mediterrnean ships anyway, so it won't greatly matter.

Caution: Hull subject to strain in open-sea
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent

Very potent small cruiser. Using 0,75 instead of 1,00 for hull-strength helps a lot, as it seems. :o)

I think the bc used is a little bit low for a ship her size, isnt´it?

Some nit picking:

Your ships 3ts too heavy for said rules as they are referring to standard, not light displacement.

Should be easy to fix. Just increase her range a little bit, you´ve enough hull-strength left.

As I said before, these are Meditternean cruisers, not blue-water.

She got slightly larger with the advent of SSv.2 as opposed to SS ß2.

I'll just slightly increase the range.

They are definately "lookers". They also remind me of my own need to get cracking with a similar design for Atlantis. Thankfully I have a lot of older cruisers to replace.

Her turrets I like most even though the original 15cm twins used on early italian cruisers also looked cool. They just caused a lot of dispersion due to their barrels being so close to each other. Nevertheless, they looked cool....

You forgot to mention that they looked cool ;-p

Comme ça?

152/53 1926 Ansaldo
Used onboard the Di Giussano class. The only model with loading only at the fixed elvation of 20°.

152/53 1929 OTO
Used onboard the Diaz, Attendolo and Aosta classes.

These two models were to be used with the same ammos, with similar dispersion problems. The initial speed, at the beginning near to 1000 m/s, was again reduced by 100 m/s, but the dispersion remained significant.

However at the moment I am using a 6"/50 gun, which doesn't have quite the same performance but isn't likely to blow up in my face. In the future, I'll probably move to the 6"/53 M1929 or something else.

Good armor for the size, and nice looking, when they aren't a 34-kt blur.

So far I've been patterning my 1930s CLs after the RL Leipzig and Nurnberg; might have to make a few revisions now.
