Any ship designs for Northampton or Helena?

Helena is in my encyclopedia, she's a Columbia class CL which is an upgraded Omaha based on a design Alt Naval did on his Naval Counterfactual site. I'll get the other CA's up this weekend.

I'm assuming here (which is always a dangerous thing to do) that the Northamptons are as historical or very close to it?

Pretty much, though they have better armor.

No machine guns?

Kato, you fool!! You shouldn't have said that! Now he will redo the design to remove the weakness!!!
:-)

The weapons are based on the original design and don't take into account the greater air threat in our universe. Thanks for reminding me to change it though!

Well it looks like Mitchell's tests didn't have any influence on the high ranking officers thinking then...

Mistake number one: officers and thinking in the same sentence.

I think the Navy's hatred of Mitchell overrode any test results. He apparently was quite abrasive to say the least.
