An artifact of RA.
From what I can see, the only cruisers he had simmed with sonar are the San Calepodio class, the Ischia class, and the Rimini/Bari class.
Bari and Rimini, and in a way the Ischia too, are more like oversized destroyers. So that would leave the San Calepodio as being the odd one, but looking at the picture, it makes me wonder if RA had the idea of using that autogyro/helicopter contraption thingie in the ASW role with the sonar being used to locate the submarines...

I think the real savings in tonnage is going to come from cutting hull numbers and rejigging lay down dates than resims. I still haven't seen enough, if any, tonnage savings to justify the wholesale resimming of ships. They all look good sims but its not fundamentally altering the problem at hand - the shortage of factories.
... I'm unsure of the best way to continue here, it seems like just going through and eliminating ships might be the best way to go. *starts thinking about how to trim 200,000t of ships*

Exactly so. As we discussed via PM with the other mods before this all came public, I'm fine with resimming certain classes to make them fit into the budget, but we'd prefer not to introduce too many wholesale changes to existing designs. In other words, we'd prefer to resim ships only when the sims are wrong, or when the ship class (even properly simmed) can't fit into the budget unless it's reduced in size and scope.

Quite correct Walter - drawing out the construction time to fit the available tonnage is one way of addressing the problem. I've done it when constructing the Sachsens - essentially suspending them for the best part of a year and then slowing their build tempo.
I think Walter has some good points here, but I think Bruce's quarter by quarter approach might bear fruit too.
