In 1942 a 2-meter bulge was added to the starboard size to increase stability and fuel capacity. So here it is in the model.
I've also built the propeller shafts, but I won't build the propellers until later.

Outstanding work on the starboard bulge.

I always wondered how these ships had to set their rudder to account for the odd bulge making the hulls asymmetric. Such a massive superstructure on these ships. Weird how gpm adds the bulge as a add on almost after the fact like the real ships.

Never known this detail about the asimetric Hull. Very huge model indeed, but your mastery will permit you complete.
Best, Nando

Paper Fan, the huge funnels on the Lexington class aircraft carriers (and to a slightly lesser extent on the Yorktown class) are somewhat visually misleading. Since their sole purpose was to direct hot boiler exhaust away from the flight decks, the funnels were formed from much thinner steel sheets than the hull plating. Upper superstructure elements tend to be very lightweight to keep the center of gravity as low as possible for stability. Since these carriers would usually be steaming into the wind during air wing operations, the effect of cross winds acting on such large funnels was minimized. On other occasions when under way with the wind blowing across the deck, that funnel would definitely be an issue.

When the Saratoga was hit by the blast from "Able" (the first Bikini Atoll A-bomb test), the funnel was completely knocked over, as she was anchored with one side fully exposed. That was the most significant damage she suffered. "Baker" was the underwater test, which sent a deadly shock wave while dumping tons of seawater unto the flight deck, causing a partial collapse and swamping the carrier. The caved-in flight deck can easily be seen by divers today.

Here is a rather impressive picture of her caught in the nuclear explosion.

It would seem very likely that the hull bulge had some effect on her overall sailing characteristics.

I had trouble believing that the photo (of the Baker test) was taken 10 seconds after detonation, but checking video footage does confirm this. Saratoga was relatively far away from the Able air detonation, but the Baker underwater explosion sure did the damage.
Still, a sturdy vessel if it takes 2 nuclear explosions to convince her to sink, hesitantly.

Correction: I understood that the Saratoga's funnel was toppled by Able, but a recheck confirms that Baker sent it down. It took about seven hours before the Saratoga sank. In comparison, the battleship USS Arkansas was literally flipped over by Baker and sank almost immediately. She's still upside-down on the bottom of Bikini Atoll.

Not all of the ships were positioned the same distance from the epicenter, so comparing damage from one to the next is really not fair. You can see what appears to be a hole in the water column on the right of the Baker test that is where Arkansas was located. Baker had way more effect since it was a subsurface blast, the pressure wave through the water was way more destructive than that of Able.

The tests proved for the most part, other than near direct hits, surface warships were structurally able to withstand the bombs of that era. Of course any crew would have died and the ships were useless radioactive hulks afterwards anyway.
