Oiler or Tender?
The 50+200+410 = 650t "Resupply" or "Fleet Supply"
As that just supports a cruiser (6500t)

But is the 1900+2500 = 4400t "of oil" also meant as "resupply" ?
Or a means of refueling the fleet when the standard supply train may not be sufficient ?

4 x 4650t Armored Gun Boats were scrapped in 1933H2.
In parallel with the 8000t cruisers, Byzantium built 4100t AGBs to protect the "big ones" from DDs and aircraft.
They are also capable of working in addition to the 8000t.
3T2 x 152/50 (HMS Ajax guns) were preferred to 4T1x191/45 for the volume of fire.

The ABG4100 is only 1/4 larger than the ABG3000, but has 50% more firepower, and armor.
I would think it would be worth having fewer hulls with that better capacity.

4 guns, 3 on broadside, are not going to have the ROF for splash FC. So the ship would be very dependent on aerial spotting. There is no margin of speed there either.

Parthia thinks the Byzantines should build lots and lots of these !

Quote...So the ship would be very dependent on aerial spotting...

This is monitor for Red Sea & Aden Gulf, not an armored cruiser.

I have also SS a la Tone/Chikuma.
This is very interesting to have independent aerial spotting for Red Sea & Aden Gulf.

Interesting 2T2 forward, but 'cheek' mounts, so 6 guns dead ahead or on either beam, but 2 aft ?
I believe that is roughly how my Maelstrom cruisers are arranged.

The carrier rules have a limit of 6 to be considered not a carrier

As I've mentioned before, protective decks can be problematic.
Presuming your belt goes to -2m, then it rises 1.23m above WL.
I presume you deck heights are the standard 2.44,
which means 5.45, 3.01, 0.57m
If the crown of the protective deck is only 0.57 above WL,
then the belt is only 0.66 over the crown.

Which at longer ranges will let some shells arch over the belt and strike the slope of the PD directly.
The gun firing dictates at what slope the shell descends,
but as I recall it seems likely to occur like 18-24km and only effects a small % of the deck area, but I thought I'd mention it again.

I did math on this long long ago, and wound up with...as I recall... 1.5-2m+ over the crown as a good height. Which is part of why Parthian ships went to armored decks as Fire Control improved.

Famously one of the flaws of the USS South Dakota Class was it is apparently possible to trace a shell path that would pass over the thickened exterior shell, pass in front of the armor belt, and strike in the TDS directly, which could be bad.

one of the weird bits of design guidance is that a rise of >1.5m in the bow may not allow dead-ahead short range fire.
That's guidance, not rule, and so would depend on who is overseeing the battle.
The idea is if the muzzle heights appear to be in pictures about 1.5m-2m high, a short range
