[Kaiser Kirk]

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 ?

"squadron supply ship" with fuel, food, ammunition and various materials.

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.
