I think you may be looking at the lower image. The upper image is the current one.

Quite possible. I'm not that familiar with the Egyptian pantheon as I am with the Greek, Roman and Norse.

Nope. I'm referring to the aft DCT. As far as I've been able to gather it featured a 15ft range finder. Even with it's slimmer profile, the HACS will still get in the way. You'll need at least 7px clearance around the DCT and 5px around the HACS which has a 12ft range finder.
I'd move the aft mast and HACS forward a bit and move the armoured conning tower back a few pixels.

ah. yeah. I just checked. I uploaded the wrong image. I did my WIP instead of the one with all the changes. Thats also the one with the corrected bilge keel. I thought I had changed the directors on both, but I guess I was wrong, huh? Thats what I get for not paying attention.



So, I believe this one is now finished.

Main Battery in an "Atlanta"-type layout but with 4 beam turrets instead of 2 (16-gun broadside). The 40mm cannons are in 6 quad and 2 twin mounts. Made the following changes:

- Did some adjustment to freeboard (original numbers were a bit off)
- Heightened end belt to match main belt
- Gave some height to upper belt (original was 0'!)
- Lengthened main belt (shortening end belt in the process) to fix that problem
- Added CT and deck armor (original had _none_!)
- Dropped speed from 34 knots to 33
- Separated the Main Battery into 2 sets, now 10 turrets instead of 6. Raised 6 turrets (to reflect 2 raised and 2 double raised centerline turrets, beam turrets are not raised).
- Increased rounds for the Main Battery from 250 rpg to 450 rpg (necessary for an AA ship that's going to burn ammo fast)
- Added miscellaneous weight
- Changed the 40mm cannons from 7 quad mounts to 6 quad and 2 twin mounts, raised 4 quad and both twin mounts
- Raised 5 of the 7 quad 20mm mounts
- Put 1-inch shields on 40mm and 20mm mounts
- Added 1.5' of draft to fix seakeeping problem

Displacement increased by 61 tons, lost the "steady gun platform" rating but lost the "poor seaboat" raiting as well.

Yeah, I forgot to include the deck armor. Increasing the rounds from 250 to 450, not a bad idea. I'll not be changing the secondaries though, that stays as is, (I really don't want to have to redraw the whole thing again). I appreciate what you did though. Thanks.

No problem. It's a good design, just needed some tweaks and armor. I have a personal problem with short belts not protecting everything, larger ships being poor seaboats and main batteries incapable of end-on fire; I'll do a lot of work to fix those problems.
