I assume the crane for the seaplanes can be folded out of the way - in that case X turret's firing arc is OK.

As for Q turret, using the ol' Eyeball Mk.1 it has better than 120° arc on each beam, which isn't too bad. And (assuming super-heavy 14" shells) A and X turret between them have roughly the same punch as 'Ood, so I actually kinda like the configuration.

iunno, I've seen Canis' LDs of an American "Hood Type" on his site....

But there's that pesky 60° aft arc that might be useful when the carriers you're escorting are fleeing at high speed from mischievous Kongos or whatnot. :x

"Designs for fast battleships from the early 1930's. The second design is described as a "Hood Type" battleship."
Looks better than that other one (if this is the one you are referring to). :-)

Now that's ugly! O_O

Simple - the BCs turn broadside to head 'em off at the pass. ;-)

Better than Chesapeake, yeah, but not exactly in the Hood department looks-wise, in my humble opinion.

A zig-zag retreat course? Kinda negates any speed advantages... Like I've said, my main problem with the design (discounting looks :x ), is that it's not well thought out in light of it's stated mission. While yes, it could adapt and turn broadside, but since the ship is being designed from the outset with this specific mission in mind, it shouldn't be designed with a built-in handicap to that mission.

This is my current drawing of the Lexington after her planned mid 1930's reconstruction. I'm still debating the funnel design and may go back to the origninal twin funnels. I'm also thinking of slightly reducing her speed to 31 or 30 kts in favor of increased deck armor. Another option for BC-1933 would be to upgrade the Lexington design, possibly replacing the four triple 14" turrets with three quads. That would come out in the 38-39K ton range.

If you're planning to be modernizing the carriers at the same time, it might be cost efficient and expedient to use the the same / similar components. If not, I'd say that while it's nice to toy with the idea of the carriers and battleships that started as the same design sharing components like that, I'd have to say there's a reason why no battleship (or any ship other than a carrier, come to think of it) ever had a single huge funnel like that. The North Carolina was originally designed with one, but reverted to two relatively small stacks by the time she was built. It might be a target profile issue, or a battle damage issue. That funnel is a large target, and what're the results of a 8 inch or larger shell going through a stack? Especially something like a 14 inch shell exploding somewhere in the stack, and collapsing it? o.O

I was thinking something along the lines of the following. Ignore the lower figure, I haven't changed it. Nor, for that matter, have I made much effort to attend to details in the side view that I did play with. Just want to show the general notion I had.

Looks interesting. Another option would be to move a couple of the 5" guns to the centerline and move the catapults to the midship area, clearing the fantail arcs.

Looks a bit better than the Chesapeake, but still on the ugly side. If you're building a bigger ship, might as well be a Lexington follow-on.

Hey, Rocky! The side and top view don't match! ;-)
(Just had to say it, eventhough you have mentioned it)
Actually, for some reason stuffing the upper works of the Intrepid onto the Lexington hull makes it look much more acceptable...
... so is the hull to blame for the ugliness of the original design?

When I was trying to pattern a CA after the Chesapeake design, I finally concluded that my CA/BB type superstructures were more suited to a...vertically stacked (?) layout than a stretched out, non-superfiring layout. Trying to incorporate features of both just leads to problems.

I think that's also true of a lot of American capital ship designs; but the Lexingtons are long, sleek ships with low-ish profiles, so I think their lines work with a Chesapeake layout.

Whether it's practical is another matter, but I do still kinda like Canis' original drawing as a very business-like capital ship.
