I agree, and I argued much the same just last night on IRC. The "Essex 1.5" would settle all of my concerns about size. As Jason said to me, it's the Goldilocks design: not too big, not too small, just right.

Remember that the F7F was designed to fit a Midway class, not a Midway to fit an F7F!

Yes and as I said, I shall build the Goldilocks carrier, and not the Midway 0.5. So whats the deal?

I'm intrigued by the "Goldilocks" carrier as it's dimensionally the same as an Essex but much heavier. The block coefficient used seems very full for a ship like this. I'd have a look at lowering it to ~0.50 which'll reduce the power requirements significantly.

Also square root of 11750t gives 108 aircraft rather than 91, so there might be some fat there to trim as well.

Oh I could probably tweak Goldilocks somewhat and get the tonnage down to around where Essex was historically, but this does allow some growth potential for future rebuilds/refits. The carrier is to last until the 1970's after all, so yes it may be a bit heavy at the present but 10 or 20 years down the road the USN will no doubt appreciate the extra weight. Perhaps it is a bit foreshawdowing, but the USN did build ships historically to last several decades in active service, so its not that much of a stretch that they would do so in this case.

And it also means the USN is relegated once again to building a ship which I will note would be 10,000 tons lighter than your own carriers laid down 2 years earlier, and 5,000 tons less than the Iberian carriers already in service. And we all know how Americans think, bigger equals better, my source on this is Mister Jeremy Clarkson :D.

For what it's worth, Canada's been fairly satisfied with it's rebuilt Courageous and Glorious (and soon, Furious). But the RCNAS is only just starting to aquire modern aircraft, too.
