Well most of the paper designs and non-historical upgrades are falling into the same category in the game, with a hefty dose of artistic license taken.
I think we're basically barking up the same tree here.
They actually have a real shipbuilding engineer on their staff so probably they are not so far off.
Yes, this seems to be trotted out whenever questions are raised about their designs. I'm sure from an engineering perspective the design is sound and the hullform is correct and has a proper cB or whatever other springsharp-y nonsense applies -- I am personally not interested in this stuff as I am not a naval architect. All I can comment on are irregularities in detail stemming from my own years of research into USN surface combatant fit & design practice of the time.
In case of 4C it was a preliminary sketch design only, not a detailed, down-selected one so I think what they have done to it is within the acceptable limits (maybe not the main battery change). Same for Seattle (T9 ship, based on Worcester class prelim).
Again, this is a fair assessment -- I'm not disputing that Dallas was "based on" 4C. I think it should be fairly obvious that 4C was modified way beyond the original sketch to create Dallas (is really all I'm saying here).
On the directors from the drawing it appears they got at least the order of placement right, the rest (type is hard to tell at best), but since this design is concurrent/immediately subsequent to the Brooklyn class design effort I'd take those ships as a base reference.
Yes, I'd stand by my original comment about 4C being designed with Mark 31 directors for the 6" guns though. The darkened spotting glasses turned fore & aft on the sketch seem to indicate this. The New Orleans class cruisers had these directors above their pilothouses, with the foundations surrounded by battle lookouts -- this would line up nicely with what WG has portrayed on Dallas, with the director foundations fore and aft surrounded by surface lookout positions with viewing slits.
Anyway, think we've beaten this one to death by now.
