[Kaiser Kirk]

I looked at battlewagons in that size range, almost went with the 45,000t 8x435mm.
Adds 2 HY to the build time, but average cost is slightly less to go to 54,000.

How is the 180mm multiple decks arranged?
I see an 100mm upper belt, is there a 40mm splinter deck over 140mm main deck arrangement?

You have large amounts of misc weight, as we all do these days.

Curious such a big ship has 1 AC, and 30t instead of 25?
Likewise, Enhanced Hydrophones are 15tons.

As typical you allocated a tremendous amount to pumps in addition to the standard ones.

Ironically, I try to keep draft below the Real-life WWII limit for Suez, despite Snip eliminating that, and Parthian warships not expecting to rely on Suez. So there is no reason for me to stick at 9.6 so often.

[Kaiser Kirk]

If the Byzantines need some funds to upgrade plans from "confine a possible explosion to the hangar" to "remote detonated explosion to the hangar", Parthia may be able to help !

Interesting in light of my recent Afson class.

I've got a Light Carrier class I'm considering at 15,000 tons, or 24months time.
Not sure if that will be a 1938.5 or a 1939 laydown, but leaning towards 1939,
so I'll have to rework it.
But then..2 of those, or 1 bigger carrier?

The Baskuc armored carriers are meant to ensure I'll have operating flight decks,
but armored carriers have to sink so much tonnage into armor, they are expensive
for the number of planes. So a mixed force seems the better choice than an all-Armored carrier force.
