Is here.

Quite a nice looking design, and as advertised very potent armament wise!

Theres a problem with nicking stuff off other people's drawings; its not always the same scale.

Those triple 150mm guns are huge compared to the rest of the ship. Try these turrets instead;



And shes only heavily armed for the moment...

AdmK,

your latest drawing offers some nice details but there are some things to consider.

1.) Main turrets and barbets are out of scale and way too large.

2.) Barbets shouldn´t be larger in diameter than one third of the ships beam due to structural integrity of the hull.

3.) (Aft) Main armament too close to the bows. This is coupled with point 1.). So close to the stern there won´t be enough hull space for barbets of that size, shafts, magazins etc.

I propose to cut away her crane, move everything behind (superstructure, turrets) forward close to the hangar and place new cranes (one at each side) abreast her second funnel.

Regards,

HoOmAn

Are you hinting that the Italian special forces are going to dis-arm her?

I like the design until such time as several of the class deploy to my region. I'd echo the comments made about the drawing.

The Decima MAS (see avatar) are currently in training and cannot undertake any missions in the near future.

I was actually meaning the arrival of CLs with 15x6" guns in triples. But who knows? there might not be any.

I've toyed with the idea of a 15 gun CL in my eastern operating areas, but am not yet sold on it.

Problem is, anything over 8,000 t is a Type 1 cruiser, so you'd only be able to operate a few.

Wonder if anybody's ever designed an 18 gun CL...

You mean somehing like this? Main gun caliber might not be that big, but still, 18 guns are 18 guns.

I'm very interested in 15x6" and 12x8" designs, and I've even toyed with some drawings. For now Atlantis will consintrate on heavy cruisers and updating its existing ships. Once this is out of the way you can take it to the bank Atlantis will build some light cruisers.
