is this the tonnage Italy officially declares? I'd suggest declaring the fake tonnage here and the correct design over at the design board.

I think Springstyles should be accurate, just to keep things simple. It's data for press releases that get fiddled with.

This is her actual stats. The released statistics are that her displacement is 8,050t. The problem is those 10" gun turret that are being reused. Much more work has had to into them than was originally thought when the design was approved. Some late corrections had to be made that push her slightly over the limit.

Any secrets with that 1mm AA shield? Seems to be rather thin to be used for protection.

Walter

Well springsharp won't let me enter in a thickness greater than 1mm and as my picture shows gun shields i thought that i'd better put some weight for them in.

Odd...
It should be able to accept a greater thickness...

"AA gun armor restricted to 1 inch maximum" ?
Shouldn't be a problem (read: "ignore the warning"). For some reason SS thinks that when you enter a mm thickness for the shields, that they are equal to an inch and thus gives that warning if you get over 1mm. But it shouldn't give any problems with the design in the end.
Let's hope this minor error will be removed in the future version of SS.

Walter

Thats the one. The entered number also turns red. Its probably because i'm working in metric.

Well, looking at the design, you work both with metric and imperial.
Still, it should be no problem if you were to enter 20mm or so for the shields. The warning does not pop up in the datafile. Didn't LordArpad had guns with 20 inch shields due to a metric/imperial error he made with entering the data into SS?

Walter

I had indeed - not to mention the 17 mm Torpedoes ;-)

...those Iberian cooks are pleased with the snafu though, now they can cook all the fish they want!
